Astronomy Daily S05E148 — "Far Side" Thursday 23 July 2026 Starship gets a second shot at Flight 13 — with a schedule caveat worth knowing about. The first far-side lunar samples reveal that Earth has been quietly shielding the side of the Moon that faces us. Astronomers debate whether the lunar far side should be closed to industry. The Milky Way's only helium nova finally steps out from behind twenty-five years of dust. And the case that our entire galaxy once turned over. Plus a skywatch closer with a straightforward piece of advice about the Delta Aquariids: do not wait for the peak.In this episode Starship Flight 13 ●        Window opens 6:45pm EDT / 2245 GMT Thursday 23 July — 8:45am AEST and 10:45am NZST Friday 24 July. ●        Schedule is not locked: Starbase road and beach closure notices point to further Pad 2 testing. ●        The 16 July attempt aborted at T-0 when four of 33 Raptors missed start parameters; the limit is three. ●        Two Raptors were removed and replaced before this attempt. ●        First-ever Starship deployment of V3 Starlink satellites — 20 of them. ●        Super Heavy splashes down in the Gulf at ~7 minutes; Ship targets the Indian Ocean off Western Australia at ~65 minutes. No catch attempts. Chang'e-6 and the solar wind ●        Published in Nature Geoscience by a team at the Chinese Academy of Sciences' Institute of Geology and Geophysics. ●        Based on 1,935 grams of regolith returned from the South Pole–Aitken basin on the lunar far side. ●        First direct laboratory comparison of solar wind implantation between the near and far sides. ●        Far-side soil records faster, deeper-penetrating particles; the neon isotope ratio sits below every near-side sample measured. ●        About a quarter of the solar wind exposure at the Chang'e-5 near-side site involved wind decelerated by Earth's magnetosphere. The far-side site shows none. ●        Opens the possibility of using lunar noble gases as a fossil record of Earth's magnetic field over deep time. The far side debate — NAM 2026 ●        Held Tuesday 21 July at the RAS National Astronomy Meeting, University of Birmingham. Convened by Prof Martin Ward. ●        For the motion: Prof Joe Silk (Johns Hopkins) and Dr Jonathan McDowell (Durham Space Research Centre). ●        Against: Dr Nikita Chiu (Durham) and Dr Manuel Salvoldi (aerospace engineer and educator). ●        For: the far side is the only radio-quiet site near Earth — critical for detecting the cosmic dark ages, and an exceptional platform for gravitational wave detection. ●        Against: commercial investment is what makes lunar exploration sustainable, and governance can let science and industry coexist. ●        Audience support for the motion rose from 68% to 76% across the debate. V445 Puppis ●        Presented at NAM 2026 by John Mills, University of Warwick. ●        The only confirmed helium nova in the Milky Way. Erupted in late 2000, then vanished behind its own dust for over twenty years. ●        Now confirmed as a white dwarf accreting from a rare stripped helium star — only a few thousand such stars are thought to exist in the entire galaxy. ●        Orbital period of 3.7 days, roughly double previous estimates. Mass transfer has resumed. ●        Unexplained high-speed "bullets" of possibly oxygen-rich gas travelling up to 20 million mph (~9,000 km/s) — never seen in any other nova. ●        Data from ESO's Very Large Telescope, Hubble, the Southern African Large Telescope and TESS. ●        Helium novae may be one pathway to Type Ia supernovae, the standard candles used to measure cosmic expansion. The Milky Way disc flip ●        Presented at NAM 2026 by Kirill Batrakov, Durham University. ●        Based on 25 Milky Way-like galaxies in the Auriga simulation suite, followed across roughly 11 billion years. ●        Galaxies with the most slowly rotating stellar haloes shared a major head-on merger and a disc reorientation greater than 90 degrees. ●        Our stellar halo rotates at only 10–20 km/s; the disc moves at around 220 km/s. ●        The Gaia-Sausage-Enceladus collision roughly 10 billion years ago is the candidate trigger. ●        Batrakov describes a disc flip as likely rather than confirmed, and is looking for independent signatures. ●        Separate 2026 work led by Ling Zhu, using 600,000+ giant stars from Gaia and LAMOST, found the outer dark matter halo oriented almost vertically to the stellar disc — consistent with the disc having tilted. Skywatch ●        Southern Delta Aquariids are active now, running into late August, with maximum around 30 July. ●        Full Moon on 29 July means peak night is close to 98% illuminated — the worst conditions of the run. ●        Best window: the pre-dawn mornings from now until roughly 27 July, after moonset. ●        Radiant near Skat in Aquarius. Use Fomalhaut and the Great Square of Pegasus to locate it. ●        Australia and New Zealand: radiant climbs near overhead. Best from around 2am to first light. ●        North America: radiant sits low in the south — fewer meteors, but a better chance of long-trailed earthgrazers. Same 2am-to-dawn window, local time. ●        Sunspot region AR4493 has grown rapidly to beta-gamma-delta complexity — the highest classification — and has already fired three M-class flares in a day. Worth watching aurora alerts.

Zeitgeist #23 s analytikem Matějem Prášilem a biologem Markem Stibalem o polární geopolitice, unikajicím metanu, životě na ledu i pod ledem v Grónsku, vědeckých expedicích i ledních medvědech. Zahřívání planety se s největší rychlostí projevuje v Arktidě. Masy ledu kolem severního pólu mizí v moři s nebývalou rychlostí a odhalují nové příležitosti a výzvy v oblasti, kde se překrývají mnohé obchodní, těžařské, vojenské a další zájmy. Námořní spojení mezi Evropou a Asií přes tající Arktidu může být až dvakrát rychlejší ve srovnání s cestou Suezským průplavem - namísto čtyřiceti dnů možná jen dvacet. Polárními vodami tak v létě brázdí čím dál víc lodí. Stejně tak se nabízí a plánují nová propojení podmořskými kabely – třeba spojení mimo jiné mezi Kanadou, Grónskem, Islandem, Irskem a Japonskem. A mnozí si brousí vrtné soupravy na obří naleziště ropy, zemního plynu, vzácných kovů a zemin tak potřebných pro nové technologie a zelenou tranzici. Není proto divu, že některé tradiční arktické země vznášejí nové nároky. Státy jako Dánsko, Rusko, Kanada nebo USA se dohadují komu patří podmořské hřbety a potenciální bohatství, které skrývají. A za osmi arktickými zeměmi sdruženými v Arktické radě se hlásí o slovo další jako Čína, Indie ale i evropské státy, které leží od Arktidy poměrně daleko. Přinejmenším od začátku ruské invaze na Ukrajině je také jasné, že Arktida nemusí být předmětem jen rétorických a soudních sporů a vojenských manévrů ale i otevřených konfliktů.Grónsko mnohé z těchto a dalších trendů vyjevuje bez příkras a v plné síle jako na ledovcovém projekčním plátně, které se bude postupně zmenšovat pod vlivem postupující změny klimatu. Největší ostrov světa odhaluje mnohé příležitosti. Posiluje strategický význam, který měl vždycky a láká zájem velmocí v čele s Čínou a Spojenými státy. Letos to v jednu chvíli vypadalo tak, že se USA pokusí autonomní území od svého dánského spojenc a Gróňanů vzít silou. To se podařilo zažehnat i díky rozhodné reakci evropských zemí. Ale zájem USA o území nepolevuje a Grónská krize může být prvním dějstvím nové fáze dobývání Arktidy. O proměnlivých zájmech různých velmocí v oblastech kolem severního pólu v důsledku postupující změny klimatu a poučení z Grónské krize mluví v podcastu Zeitgest expert na geopolitiku Matěj Prášil. Výsledky dlouhodobých výzkumů Grónského ledovce a otazníky nad množstvím skleníkových plynů uložených pod ledem i zkušenosti polárních expedic přibližuje biolog Marek Stibal z Přírodovědecké fakulty Univerzity Kalovy, který je spoluautorem nové studie publikované v Nature Geoscience mapující metan unikající ze západní části Grónského ledovce.

Beim Thema Klimawandel erhitzen sich nicht nur die Temperaturen - sondern schnell auch die Gemüter. Ob Hochwasser, Stürme oder Hitze: Schnell heißt es, daran sei der menschengemachte Klimawandel schuld. Doch lässt sich das so sagen? Mit dem Wissenschaftsjournalisten Axel Bojanowski habe ich über die Erderwärmung, die Klimalobby, ausbleibende Kritik im Journalismus, Macht, Alarmismus und das Isntrumentalisieren von Ängsten in Bezug auf das Thema Klimawandel gesprochen. Aber auch über das Klimathema als Ersatzreligion, ständig neue Deadlines, bis zu denen man handeln muss, ehe der "point of no return" erreicht wird sowie die Energiewende in Deutschland und ein mögliches Comeback der Atomenergie. Bojanowski diplomierte an der Universität Kiel über Klimaforschung. Seit 1997 arbeitet er als Wissenschaftsjournalist, u. a. für "Die Zeit", "Nature Geoscience", "Stern" und "Süddeutsche Zeitung". Er war zehn Jahre Redakteur beim "Spiegel". Seit August 2020 ist er Chefreporter für Wissenschaft bei der "WELT" und schreibt eine Klimakolumne für die "BILD". 2024 ging er u.a. dem Lobbyeinfluss bereits in seinem Buch "Was Sie schon immer übers Klima wissen wollten, aber bisher nicht zu fragen wagten: Der Klimawandel zwischen Lobbygruppen und Wissenschaft" nach, zuletzt erschien "33 erstaunliche Lichtblicke, die zeigen, warum die Welt viel besser ist, als wir denken."

The NASA Curiosity Rover has shown us evidence of ancient rivers and bodies of liquid water on the martian surface. Given it's thin cold atmosphere, seeps of liquid water, presently on the surface of Mars which are capable of hosting microbial life appear to be unlikely. Scientists were thus surprised when high resolution imaging of the red planet's surface revealed thousands of intriguing dark streaks called RSL on hundreds of rocky slope areas. These fascinating features slowly extend down hill and grow during the martian warm season, fade during the colder season, and reappear during the next martian warm period. On Earth features like these are produced by seeps of liquid water. However, on Mars a careful study of 151 RSL features at ten different sites using the high resolution camera on NASA's Mars Reconnaissance Orbiter reveal that they occur almost entirely on slopes which are greater than 27 degrees. This new research published in Nature Geoscience suggests that RSL are composed of solid particles in dry granular flows which unlike water seeps appear to end on many of the dunes when it's slope falls below a critical value. What makes RSL tick remains a mystery and likely involves small amounts of water trapped from the atmosphere. Currently surface conditions are hostile to life as we know it, however, the possibility of finding evidence of ancient life or perhaps even still existing microbe colonies in deep sub surface pockets of water are reasons to continue to explore our next door neighbor without contaminating it.

Gold is one of the most chemically inert elements on the periodic table, and the fluids that carry it through the crust contain barely any of it… so how on Earth do we end up with enormous gold nuggets? Dr Chris Voisey, research fellow at Monash University, joins Wonder to talk about the geology of gold deposits, the mystery of how gold nuggets actually form, and the weird property of quartz crystals that might hold the answer: piezoelectricity. This is part 1 of two conversations we have with Chris – say tuned!!Find more from Dr Chris Voisey from his piece in The Conversation, 'How do you make a giant gold nugget?

Researchers propose that a clump of fermionic dark matter might exert similar gravitational influence as the supermassive black hole at the galaxy's center, Sagittarius A. This theory challenges conventional understanding and is supported by data from the European Space Agency's Gaia mission, which mapped the galaxy's outer halo and rotational curve, indicating a potential new model for understanding galactic structures.Lunar Far Side's Cooler InteriorRecent findings published in Nature Geoscience indicate that the lunar far side may be significantly cooler than the near side. Analyzing samples collected by China's Chang'e 6 mission, scientists discovered that the far side's regolith formed from lava at temperatures approximately 100 degrees Celsius lower than those from the near side. This study provides insight into the Moon's geological history and the uneven distribution of heat-producing elements, which may have resulted from ancient impacts or tidal forces from Earth.Jupiter's Slimmer ProfileNew measurements from NASA's Juno mission reveal that Jupiter is actually slimmer than previously thought, being about 8 kilometers narrower at the equator and 24 kilometers flatter at the poles. These findings refine our understanding of the gas giant's shape and have implications for models of planetary formation and evolution. The data also sheds light on Jupiter's atmospheric dynamics, including its powerful winds and cyclones, enhancing our knowledge of gas giants both within our solar system and beyond.www.spacetimewithstuartgary.com✍️ Episode ReferencesMonthly Notices of the Royal Astronomical Society, Nature Geoscience, Nature AstronomyBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/support.(00:00:00) New study claims that mysterious substance called dark matter could be powering our Milky Way(00:08:01) New study suggests lunar far side may be a little bit colder than near side(00:12:52) Space Time is brought to you by Squarespace. com spacetime(00:14:23) New measurements based on NASA's Juno mission reveal Jupiter is much smaller than previously thought(00:18:16) People with depressive personalities far more likely to have sexual fantasies, study finds(00:20:34) New test shows artificial intelligence chatbot admitting it would kill to save itself(00:27:09) Already we have security companies treating AI chatbots like humans

Quand on pense à la disparition de la vie sur Terre, on imagine souvent un scénario brutal : un astéroïde, une guerre nucléaire ou encore le Soleil qui explose. Pourtant, les modèles scientifiques indiquent un destin bien plus lent et inéluctable. D'ici environ un milliard d'années, la planète ne sera plus habitable, car l'oxygène atmosphérique, indispensable à la vie complexe, aura presque totalement disparu.Ce phénomène découle de l'évolution naturelle de notre étoile. Le Soleil, en vieillissant, devient progressivement plus lumineux : son intensité augmente d'environ 10 % tous les milliards d'années. Ce surcroît d'énergie modifie profondément le climat terrestre. À mesure que la température moyenne grimpe, l'évaporation des océans s'accélère. Plus de vapeur d'eau dans l'atmosphère signifie davantage d'effet de serre, ce qui amplifie encore le réchauffement : un cercle vicieux s'installe.Or, cette vapeur d'eau est fatale aux organismes producteurs d'oxygène. Les cyanobactéries et les plantes, qui réalisent la photosynthèse, voient leur activité s'effondrer. L'augmentation des températures perturbe leur métabolisme et entraîne une baisse massive de la production d'oxygène. Une étude publiée en 2021 dans la revue Nature Geoscience par Kazumi Ozaki (Université de Toho, Japon) et Christopher Reinhard (Georgia Tech, États-Unis) a modélisé ce processus : dans environ un milliard d'années, la concentration d'oxygène dans l'air chutera à moins de 1 % de son niveau actuel.Concrètement, cela signifie la fin de la biosphère telle que nous la connaissons. Les animaux, qui dépendent de la respiration aérobie, disparaîtront rapidement. Les plantes, elles-mêmes fragilisées, s'éteindront à leur tour. L'oxygène, qui représente aujourd'hui 21 % de l'atmosphère, n'aura été qu'une « parenthèse » dans l'histoire de la Terre : il n'est présent à de tels niveaux que depuis environ 2,4 milliards d'années, à la suite de la « grande oxydation » provoquée par les micro-organismes photosynthétiques.Après ce déclin, la Terre redeviendra un monde dominé par des formes de vie simples, adaptées à des conditions pauvres en oxygène, un peu comme celles qui existaient avant l'apparition des animaux complexes. Les seules survivantes seront probablement des bactéries anaérobies, capables de tirer de l'énergie sans oxygène, et des micro-organismes extrêmophiles, résistants à la chaleur et aux radiations.En résumé, dans un milliard d'années, ce ne sera pas une catastrophe soudaine mais une lente asphyxie. L'oxygène, ressource vitale pour la faune et la flore, aura disparu, conséquence directe de l'évolution solaire et de l'arrêt progressif de la photosynthèse. La vie complexe sur Terre n'aura donc été qu'un épisode transitoire dans la longue histoire de la planète. Hébergé par Acast. Visitez acast.com/privacy pour plus d'informations.

During this encounter, the probe reached speeds of 687,000 kilometers per hour, gathering invaluable data on solar wind and solar activity as the Sun approaches its solar maximum. The mission aims to deepen our understanding of the Sun's behavior and its impact on space weather, which can affect technology and human activities on Earth.Deep Earth Pulses: A New Ocean in the MakingScientists have detected rhythmic surges of molten rock rising from deep within the Earth beneath Africa, revealing a dynamic mantle plume that is gradually tearing the continent apart. This groundbreaking research, published in Nature Geoscience, indicates that the Afar region is experiencing the birth of a new ocean basin due to the interaction between tectonic plates and the pulsing mantle below. The study highlights the complex relationship between the Earth's interior and surface processes, offering new insights into volcanic activity and continental breakup.Aeris Rocket Launch Window OpensMission managers at Gilmour Space are preparing for the opening of a new launch window for their Ares orbital rocket's first test flight, set to begin tomorrow. Following earlier technical issues, the team is closely monitoring weather conditions as they aim to launch the first all-Australian designed and built launch vehicle since the 1970s. With ambitious plans for future versions capable of carrying heavier payloads, this test flight marks a significant step in Australia's growing space industry.www.spacetimewithstuartgary.com✍️ Episode ReferencesNature Geosciencehttps://www.nature.com/naturegeoscience/NASA Parker Solar Probehttps://www.nasa.gov/content/parker-solar-probeGilmour Spacehttps://gilmourspace.com/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.

Cela fait maintenant plusieurs années que les géologues scrutent avec fascination un phénomène spectaculaire en Afrique de l'Est. On y observe en effet la lente ouverture du Rift est-africain, une immense fracture qui s'étire sur plus de 3000 kilomètres, du nord de l'Éthiopie jusqu'au sud du Malawi. À la surface, cela ressemble à une série de vallées, de failles, de volcans, de lacs allongés. Mais en réalité, ce que nous voyons n'est que la manifestation visible d'un gigantesque processus en profondeur.Comment expliquer ce phénomène ? A cause de la remontée de roches brûlantes venues du manteau terrestre, à plusieurs centaines de kilomètres sous nos pieds. Ce que les géologues appellent un panache mantellique. Cette colonne de roche partiellement fondue, plus chaude et plus légère que son environnement, pousse vers la surface, fragilisant la croûte terrestre.Grâce à l'imagerie sismique — une technique qui permet de "voir" l'intérieur de la Terre en analysant la propagation des ondes sismiques — les chercheurs ont mis en évidence cette anomalie thermique sous la région. Une étude parue en 2023 dans la revue Nature Geoscience a confirmé que le panache mantellique sous l'Afrique de l'Est était à l'origine de l'amincissement progressif de la croûte.Conséquence directe : la croûte terrestre se fissure, s'étire. En Éthiopie, au niveau de l'Afar, des failles béantes de plusieurs mètres de large sont apparues en quelques jours, suite à des épisodes de volcanisme et de séismes. En 2005, une fracture de 8 mètres de large s'était ainsi ouverte en quelques heures près du volcan Dabbahu.Mais ce processus est-il en train de casser le continent en deux ? À très long terme, oui. Le Rift est-africain est considéré comme une zone de rifting actif. Si le processus se poursuit pendant des millions d'années, il pourrait aboutir à la formation d'un nouvel océan. L'Afrique de l'Est se détacherait alors du reste du continent, comme cela s'est produit pour la mer Rouge.Pour l'instant, nous en sommes aux premiers stades de cette rupture tectonique. Le taux d'ouverture du Rift est de l'ordre de quelques millimètres par an. C'est lent à l'échelle humaine, mais rapide à l'échelle géologique.Ce phénomène nous rappelle que les continents sont loin d'être immobiles. Sous nos pieds, la Terre est en perpétuel mouvement, poussée par des forces colossales que nous commençons à peine à comprendre. L'Afrique de l'Est, quant à elle, nous offre un laboratoire naturel exceptionnel pour observer ce processus en direct. Hébergé par Acast. Visitez acast.com/privacy pour plus d'informations.

Das ist ein Gespräch, das mir sehr viel Spaß gemacht. Axel Bojanowski und ich haben gleich zu Beginn der virtuellen Session losgelegt und diskutiert, bis ich dann den Notstopp ziehen musste — schließlich sollte das eine Podcast-Folge werden und nicht nur eine höchst interessante Diskussion unter vier Augen. Der Titel dieser Folge ist vielleicht kurios, aber mir ist das Zitat von Karl Popper aus den 1980er Jahren eingefallen: »Wissenschaft ist, wenn man schwarz gekleidet in einem dunklen Kohlenkeller nach einer schwarzen Katze sucht, von der man gar nicht weiß, ob sie existiert.« Davon leiten sich alle möglichen Folgen ab, unter anderem, dass Wissenschaft immer von Annahmen geprägt ist. Sie ist auch mit zum Teil großer Unsicherheit verbunden. Viel Bescheidenheit und Selbstkritik wären in der Interpretation und Darstellung notwendig. Davon ist in der heutigen Welt nicht viel zu finden. Besonders nicht Bescheidenheit und kritische, kluge Reflexion als Fundament unserer politischen und gesellschaftlichen Entscheidungen, eher aktivistische Grabenkämpfe, die mehr mit dem Circus Maximus als mit Expertenwesen zu tun haben.  Wir behandeln folglich in dieser Episode Qualitätsprobleme in der Wissenschaft, Aktivismus, die Rolle von Journalisten und Medien, Anreizsysteme, welche Themen in der Wissenschaft überhaupt diskutiert werden und von wem. Außerdem, welchen Schaden wir anrichten, wenn wir nicht mehr in der Lage sind, in kritischen Zeiten Ideen klug zu reflektieren und was wir mit unseren Kindern und Jugendlichen machen, wenn wir sie ständig mit apokalyptischen Visionen konfrontieren. Wo sind wir also falsch abgebogen? Was können wir alle tun, damit wir ein positives Bild der Zukunft entwickeln können und wir wieder darüber sprechen, wie wir Fortschritt erzielen können und nicht nur ständig im defätistisch/apokalyptischen Denken stecken bleiben. Ich sollte an dieser Stelle nicht vergessen, meinen Gast vorzustellen, auch wenn ihn die meisten sicher schon kennen: Axel Bojanowski diplomierte an der Universität Kiel über Klimaforschung. Seit 1997 arbeitet er als Wissenschaftsjournalist, u. a. für "Die Zeit", "Nature Geoscience", "Geo", "Stern" und der "Süddeutschen Zeitung". Er war Redakteur beim "Spiegel" , dann Chefredakteur bei "Bild der Wissenschaft" und "Natur". Seit August 2020 ist er Chefreporter für Wissenschaft bei "WELT". Bojanowski hat fünf Sachbücher verfasst. Der Berufsverband Deutscher Geowissenschaftler hat ihn 2024 für seine publizistischen Leistungen ausgezeichnet. Aus meiner persönlichen Sicht ist Axel Bojanowski einer der besten Wissenschaftsjournalisten, die ich kenne. Gerade im deutschsprachigen Raum würden wir viel mehr Journalisten seiner Güte dringend benötigen. Er hat auch zwei wichtige und sehr zugängliche Bücher geschrieben, deren Themen natürlich in diesem Gespräch auch thematisiert werden. Wir beginnen mit der Frage, wie die Qualität wissenschaftlicher Aussagen zu beurteilen ist. Wird es immer schwieriger zu erkennen, was ernsthafte Wissenschaft und was irrelevant, falsch oder Ideologie oder Aktivismus ist? »Science und Nature sind mittlerweile journalistische Produkte. Letztlich gelten sie als die wichtigsten Impact-Magazine für die Wissenschaft, aber eigentlich funktionieren sie nach den Gesetzen von Massenmedien.«  Es wird so getan, als ob es vollkommen klar wäre, wie man den Klimawandel begrenzt. Es wird nicht verstanden oder aufgegriffen, dass es sich um komplexe Zielkonflikte handelt. »The time for debate has ended.« Marcia Nutt Funktionieren journalistische Medien heute immer stärker so, dass es um persönliche Absicherung geht, indem man Nachrichten publiziert, von denen man annimmt, dass sie dem aktuellen Zeitgeist entsprechen und somit sozial erwünscht sind?  »Wenn man Artikel dieser Art bringt, hat man nichts zu befürchten.« Welche Geschichten erzählen wir uns als Gesellschaft und unseren Kindern und Jugendlichen? »Es handelt von weitgehend ignorierten Sensationen der jüngeren Menschheitsgeschichte der letzten 200 Jahre, also von der Industrialisierung und ihren Folgen, die die Welt besser gemacht haben, als die meisten Leute ahnen. Diese Geschichten werden kaum erzählt.« Erleben wir aktuell ein Multiorganversagen der wesentlichen Strukturen und Institutionen, die unsere moderne Zivilisation bisher ermöglicht haben? »Covid war sozusagen Klimadebatte im Schnelldurchlauf.« Sollten in einer Krise nicht verschiedene kluge Ideen unterschiedlicher Art diskutiert und abgewogen werden? »Es wurde ganz schnell verlangt, sich einem Lager zuzuordnen. Wenn man das nicht eindeutig selbst tut, dann wird man in ein Lager eingeordnet.« Was ist der Zusammenhang von Risiko, Unsicherheit und welche Entscheidungen folgen aus wissenschaftlicher Erkenntnis? »Man hat bei Covid wie beim Klima hohe Risiken mit mit großen Unsicherheiten verbunden.[…]  Dann wird aber so getan als ob es eindeutig wäre und man im Grunde ganz klare Fakten aus der Wissenschaft bekäme und Handlungsanweisungen — was nie der Fall ist. Aus wissenschaftlichen Fakten folgen keine Handlungensanweisngen. Nie.« Gibt es tatsächlich immer nur die eine richtige Antwort auf ein Problem, follow the science — alternativlos? »Es gibt wahnsinnig viele Möglichkeiten, auf dieses Problem zu reagieren [Klima, Covid|. Es ist letztlich eine Wertefrage.« Finden wir immer wieder dieselbe Lagerbildung vor, die aber aus anderen »Quellen« gespeist ist, etwa Technologieoptimisten vs. -pessimisten, Liberale vs. Etatisten, und dergleichen? Das ist sehr ungünstig, denn:  »Wissenschaft ist nun mal der beste Erkenntnisprozess, den wir haben. […] Um Wissenschaft richtig zu verstehen, müsste man aber Unsicherheiten immer klar mitkommunizieren.« Ist es besser, eine falsche Karte oder gar keine Karte zu haben, wenn man eine Wanderung unternimmt? »Es geht auf diesen Ebenen [wissenschaftliche Prozesse] immer auch um Macht, das darf man nicht vergessen. Wenn man es versäumt, sich auf die Seite zu schlagen, die den Ton angibt, dann verliert man an Einfluss.« Im Journalismus wurde jede Form der Differenzierung sofort bekämpft. Wie kann man aber als Gesellschaft unter solchen Bedingungen bei komplexen Herausforderungen klug entscheiden? Wissenschaft und Journalismus sollten aber beide Prozesse der Wahrheitsfindung sein. Betonung liegt dabei auf »Prozess« — was bedeutet dies für die praktische Umsetzung? Werden Opportunismus und Feigheit, seine eigene Meinung zum Ausdruck zu bringen, zur größten Bedrohung unserer Gesellschaft? »Journalisten sind vor allem feige.« Wie sollten wir mit Unsicherheiten umgehen? »Die Unsicherheiten aber, und das ist ein wichtiger Punkt, können gerade nicht beruhigen. Es sind die Unsicherheiten, ein Problem an sich.« Gibt es nur umstrittene und irrelevante Wissenschafter?  Falsche Prognosen und Aussagen in der Öffentlichkeit haben für opportunistische Wissenschafter auch fast nur positive Seiten und werden in der Praxis kaum bestraft. Sie können dieselben falschen Ideen über Jahrzehnte breit publik machen und werden auch noch belohnt — weil sie ja vermeintlich auf der »richtigen« Seite stehen. Die grundlegende Frage dahinter scheint zu sein: Welche Geschichten erzählt sich eine Gesellschaft, von welchen wird sie geleitet, welche sind konstitutiv für ihre Kultur und wie können wir diese ändern, um damit wieder einen positiven Blick auf die Zukunft zu bekommen? Nadelöhre der Wissenschaft Die Universitäten haben sich, wie auch die Medien, immer weiter homogenisiert — von Vielfalt leider keine Spur.  »Das Milieu verstärkt sich selbst.« Was bedeutet das, etwa am Beispiel der Attributionsforschung? Was bedeutet dies für große politische Projekte, wie die deutsche Energiewende, die nicht nur im großen Maßstab gescheitert ist, sondern auch Deutschland schwer beschädigt hat. Wer trägt dafür nun die Verantwortung? Und die Medien stimmen alle das gleiche Lied an, ohne kritisch zu hinterfragen — warum eigentlich? »Man guckt gar nicht mehr, was stimmt, sondern: Was schreiben die anderen?« Warum ist es so schwer bei Klimafragen, die Fakten korrekt darzustellen? Aktuell wird von Politik und Aktivisten ständig betont, dass es viele Hitzetote gäbe. Es wird nicht erwähnt, dass es zehnmal so viele Kältetote gibt: »Across the 854 urban areas in Europe, we estimated an annual excess of 203 620 deaths attributed to cold and 20 173 attributed to heat.«, Pierre Masselot et al Diese einseitige Propaganda wird überall in der Gesellschaft verbreitet, auch an den Schulen: »Papa, wenn der Meeresspiegel steigt, sterben wir?!« Was richten wir mit unseren Kindern an? »Der Erfolg der menschlichen Zivilisation beruht darauf, dass man sich von der Natur unabhängig gemacht hat und dass man die Natur auch für sich genutzt hat. […] Diese Geschichten des Fortschritts sind wichtig zu verstehen; gerade für Kinder!« Wir leben nicht, wir sterben in Harmonie mit der Natur: »Have you heard people say that humans used to live in balance with nature? […] There was a balance. It wasn't because humans lived in balance with nature. Humans died in balance with nature. It was utterly brutal and tragic.«, Hans Rosling Erst seit rund 100 Jahren können wir davon sprechen, dass Menschen ansatzweise in modernem Lebensstandard leben. »Wir zogen in die Stadt zu einem alten Ehepaar in eine kleine Kammer, wo in einem Bett das Ehepaar, im andern meine Mutter und ich schliefen. Ich wurde in einer Werkstätte aufgenommen, wo ich Tücher häkeln lernte; bei zwölfstündiger fleißiger Arbeit verdiente ich 20 bis 25 Kreuzer im Tage. Wenn ich noch Arbeit für die Nacht nach Hause mitnahm, so wurden es einige Kreuzer mehr. Wenn ich frühmorgens um 6 Uhr in die Arbeit laufen mußte, dann schliefen andere Kinder meines Alters [ca. 11 Jahre] noch.« »Es war ein kalter strenger Winter und in unsre Kammer konnten Wind und Schnee ungehindert hinein. Wenn wir morgens die Tür öffneten, so mußten wir erst das angefrorene Eis zerhacken, um hinaus zu können, denn der Eintritt in die Kammer war direkt vom Hof und wir hatten nur eine einfache Glastür. Heizen konnten wir daheim nicht, das wäre Verschwendung gewesen, so trieb ich mich auf der Straße, in den Kirchen und auf dem Friedhof herum.«, Adelheid Popp ca. 1890 Ist der Mensch das Krebsgeschwür des Planeten? Was passiert, wenn wir über Jahrzehnte solche Narrative in Schulen, Universitäten und Medien verbreiten? Wird der Fortschritt paradoxerweise von denen bekämpft, die fortgeschritten sind? Welches eigenartige und ethisch fragwürdige Signal senden wir da an den Rest der Welt? »Elend bedarf keiner Erklärung. Das ist der Normalfall. Wohlstand bedarf der Erklärung.« Wir scheinen aber in einer Zeit zu leben, wo Wohlstand, zumindest für einige, so normal geworden ist, dass man jedes Gefühl für die realen Prozesse der Welt verlernt hat und ignoriert. Wo man selbst die vermeintlich wichtigsten eigenen Ziele obskuren Ideologien opfert: »Zu Zeiten, wo der Klimawandel angeblich das größte Problem ist, schaltet man klimafreundliche Kernkraftwerke ab.« Warum findet die Diskussion komplexer Phänomene so gespalten und so feindselig und gleichzeitig so pseudo-elitär statt? Wie das gut gemeinte Definieren von simplistischen Indikatoren das Gegenteil des gewünschten Ziels erreichen kann. Aus einem Indikator wird ein Götz, dem bedingungslos in den Untergang gefolgt wird. Klimaschutz nur mit Wind und Sonne ist eine Irreführung deutscher Aktivisten und gedankenloser Politik. Oder ist es vielmehr eine bait and switch Strategie? Man lockt mit dem einen, tauscht es dann aber durch eine andere Sache aus? Man lockt mit Klimawandel, möchte aber tatsächlich eine radikale politische Wende erzielen? Der Gipfel der Ideologie: ein Giga-Projekt wie die »Energiewende« ganz bewusst ohne Kostenkontrolle? Ein Bürger stellt eine Anfrage: »Zunächst dürfen wir anmerken, dass die Bundesregierung keine Gesamtkostenrechnung zur Energiewende unternimmt.«, Frage den Staat (2023) Damit bleibt noch eine grundlegende Frage: Wer soll, oder genauer, wer kann eigentlich die Verantwortung für die komplexen Entscheidungen der heutigen Zeit tragen? Soll eine Expertokratie die Welt retten, oder sind es letztens nur die Menschen selbst, die diese Verantwortung tragen müssen? Referenzen Andere Episoden Episode 125: Ist Fortschritt möglich?

Le sable est la seconde ressource naturelle la plus exploitée au monde, après l'eau. Essentiel à la fabrication du béton, du verre, de l'asphalte ou des composants électroniques, il est au cœur des projets d'urbanisation massive — et peu de pays en ont autant besoin que la Chine. Avec 1,4 milliard d'habitants et une urbanisation toujours galopante, la Chine consomme à elle seule une part gigantesque du sable mondial. Or, cette ressource devient de plus en plus rare, poussant le pays à développer son propre sable artificiel. Scientifiquement, cette démarche repose sur des constats environnementaux, économiques et technologiques.Le sable naturel, une ressource sous pressionContrairement à une idée reçue, le sable du désert n'est pas adapté à la construction, car ses grains, arrondis par l'érosion éolienne, n'adhèrent pas bien entre eux. Le sable utilisable provient donc des lits de rivières, des carrières ou des fonds marins. Mais son extraction massive provoque des dégâts écologiques majeurs : érosion des côtes, destruction d'écosystèmes aquatiques, pollution, ou encore perturbation des cycles sédimentaires. En 2019, le Programme des Nations Unies pour l'Environnement (PNUE) a sonné l'alarme sur le risque de pénurie mondiale de sable de construction.En Chine, le problème s'est accentué avec des politiques d'urbanisation intense. Résultat : entre 2010 et 2020, l'approvisionnement en sable naturel a chuté de près de 50 %, contraignant le pays à se tourner vers une alternative.Une réponse technologique : le sable manufacturéLa solution chinoise est le sable artificiel, aussi appelé sable manufacturé. Ce sable est obtenu par concassage et tamisage de roches (comme le granite, le basalte ou le calcaire), ou de résidus miniers. Les grains ainsi produits sont calibrés pour offrir les mêmes propriétés mécaniques que le sable naturel. Ce procédé, bien que plus coûteux en énergie, est maîtrisé technologiquement et peut être adapté aux besoins précis de l'industrie du bâtiment.D'après une étude publiée en juillet 2024 dans Nature Geoscience, plus de 80 % du sable utilisé en Chine aujourd'hui est d'origine artificielle. Ce basculement a été rendu possible par des politiques publiques strictes et un encadrement gouvernemental visant à limiter l'extraction destructrice de sable naturel.Une démarche aussi environnementaleLa fabrication de sable artificiel ne vise pas uniquement à répondre à la demande, mais aussi à réduire les dommages environnementaux. Elle permet d'épargner les zones naturelles, de ralentir l'érosion côtière et de valoriser des déchets miniers qui, autrement, seraient stockés.En somme, la Chine fabrique son propre sable par nécessité, mais aussi par anticipation : pour soutenir son développement urbain tout en préservant ses écosystèmes fragiles.

Listen in as Real Science Radio host Fred Williams and co-host Doug McBurney review and update some of Bob Enyart's legendary list of not so old things! From Darwin's Finches to opals forming in months to man's genetic diversity in 200 generations, to carbon 14 everywhere it's not supposed to be (including in diamonds and dinosaur bones!), scientific observations simply defy the claim that the earth is billions of years old. Real science demands the dismissal of the alleged million and billion year ages asserted by the ungodly and the foolish.     * Finches Adapt in 17 Years, Not 2.3 Million: Charles Darwin's finches are claimed to have taken 2,300,000 years to diversify from an initial species blown onto the Galapagos Islands. Yet individuals from a single finch species on a U.S. Bird Reservation in the Pacific were introduced to a group of small islands 300 miles away and in at most 17 years, like Darwin's finches, they had diversified their beaks, related muscles, and behavior to fill various ecological niches. Hear about this also at rsr.org/spetner.  * Finches Speciate in Two Generations vs Two Million Years for Darwin's Birds?  Darwin's finches on the Galapagos Islands are said to have diversified into 14 species over a period of two million years. But in 2017 the journal Science reported a newcomer to the Island which within two generations spawned a reproductively isolated new species. In another instance as documented by Lee Spetner, a hundred birds of the same finch species introduced to an island cluster a 1,000 kilometers from Galapagos diversified into species with the typical variations in beak sizes, etc. "If this diversification occurred in less than seventeen years," Dr. Spetner asks, "why did Darwin's Galapagos finches [as claimed by evolutionists] have to take two million years?" * Opals Can Form in "A Few Months" And Don't Need 100,000 Years: A leading authority on opals, Allan W. Eckert, observed that, "scientific papers and textbooks have told that the process of opal formation requires tens of thousands of years, perhaps hundreds of thousands... Not true." A 2011 peer-reviewed paper in a geology journal from Australia, where almost all the world's opal is found, reported on the: "new timetable for opal formation involving weeks to a few months and not the hundreds of thousands of years envisaged by the conventional weathering model." (And apparently, per a 2019 report from Entomology Today, opals can even form around insects!) More knowledgeable scientists resist the uncritical, group-think insistence on false super-slow formation rates (as also for manganese nodules, gold veins, stone, petroleum, canyons and gullies, and even guts, all below). Regarding opals, Darwinian bias led geologists to long ignore possible quick action, as from microbes, as a possible explanation for these mineraloids. For both in nature and in the lab, opals form rapidly, not even in 10,000 years, but in weeks. See this also from creationists by a geologist, a paleobiochemist, and a nuclear chemist. * Blue Eyes Originated Not So Long Ago: Not a million years ago, nor a hundred thousand years ago, but based on a peer-reviewed paper in Human Genetics, a press release at Science Daily reports that, "research shows that people with blue eyes have a single, common ancestor. A team at the University of Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today." * Adding the Entire Universe to our List of Not So Old Things? Based on March 2019 findings from Hubble, Nobel laureate Adam Riess of the Space Telescope Science Institute and his co-authors in the Astrophysical Journal estimate that the universe is about a billion years younger than previously thought! Then in September 2019 in the journal Science, the age dropped precipitously to as low as 11.4 billion years! Of course, these measurements also further squeeze the canonical story of the big bang chronology with its many already existing problems including the insufficient time to "evolve" distant mature galaxies, galaxy clusters, superclusters, enormous black holes, filaments, bubbles, walls, and other superstructures. So, even though the latest estimates are still absurdly too old (Google: big bang predictions, and click on the #1 ranked article, or just go on over there to rsr.org/bb), regardless, we thought we'd plop the whole universe down on our List of Not So Old Things!   * After the Soft Tissue Discoveries, NOW Dino DNA: When a North Carolina State University paleontologist took the Tyrannosaurus Rex photos to the right of original biological material, that led to the 2016 discovery of dinosaur DNA, So far researchers have also recovered dinosaur blood vessels, collagen, osteocytes, hemoglobin, red blood cells, and various proteins. As of May 2018, twenty-six scientific journals, including Nature, Science, PNAS, PLoS One, Bone, and Journal of Vertebrate Paleontology, have confirmed the discovery of biomaterial fossils from many dinosaurs! Organisms including T. Rex, hadrosaur, titanosaur, triceratops, Lufengosaur, mosasaur, and Archaeopteryx, and many others dated, allegedly, even hundreds of millions of years old, have yielded their endogenous, still-soft biological material. See the web's most complete listing of 100+ journal papers (screenshot, left) announcing these discoveries at bflist.rsr.org and see it in layman's terms at rsr.org/soft. * Rapid Stalactites, Stalagmites, Etc.: A construction worker in 1954 left a lemonade bottle in one of Australia's famous Jenolan Caves. By 2011 it had been naturally transformed into a stalagmite (below, right). Increasing scientific knowledge is arguing for rapid cave formation (see below, Nat'l Park Service shrinks Carlsbad Caverns formation estimates from 260M years, to 10M, to 2M, to it "depends"). Likewise, examples are growing of rapid formations with typical chemical make-up (see bottle, left) of classic stalactites and stalagmites including: - in Nat'l Geo the Carlsbad Caverns stalagmite that rapidly covered a bat - the tunnel stalagmites at Tennessee's Raccoon Mountain - hundreds of stalactites beneath the Lincoln Memorial - those near Gladfelter Hall at Philadelphia's Temple University (send photos to Bob@rsr.org) - hundreds of stalactites at Australia's zinc mine at Mt. Isa.   - and those beneath Melbourne's Shrine of Remembrance. * Most Human Mutations Arose in 200 Generations: From Adam until Real Science Radio, in only 200 generations! The journal Nature reports The Recent Origin of Most Human Protein-coding Variants. As summarized by geneticist co-author Joshua Akey, "Most of the mutations that we found arose in the last 200 generations or so" (the same number previously published by biblical creationists). Another 2012 paper, in the American Journal of Physical Anthropology (Eugenie Scott's own field) on High mitochondrial mutation rates, shows that one mitochondrial DNA mutation occurs every other generation, which, as creationists point out, indicates that mtEve would have lived about 200 generations ago. That's not so old! * National Geographic's Not-So-Old Hard-Rock Canyon at Mount St. Helens: As our List of Not So Old Things (this web page) reveals, by a kneejerk reaction evolutionary scientists assign ages of tens or hundreds of thousands of years (or at least just long enough to contradict Moses' chronology in Genesis.) However, with closer study, routinely, more and more old ages get revised downward to fit the world's growing scientific knowledge. So the trend is not that more information lengthens ages, but rather, as data replaces guesswork, ages tend to shrink until they are consistent with the young-earth biblical timeframe. Consistent with this observation, the May 2000 issue of National Geographic quotes the U.S. Forest Service's scientist at Mount St. Helens, Peter Frenzen, describing the canyon on the north side of the volcano. "You'd expect a hard-rock canyon to be thousands, even hundreds of thousands of years old. But this was cut in less than a decade." And as for the volcano itself, while again, the kneejerk reaction of old-earthers would be to claim that most geologic features are hundreds of thousands or millions of years old, the atheistic National Geographic magazine acknowledges from the evidence that Mount St. Helens, the volcanic mount, is only about 4,000 years old! See below and more at rsr.org/mount-st-helens. * Mount St. Helens Dome Ten Years Old not 1.7 Million: Geochron Laboratories of Cambridge, Mass., using potassium-argon and other radiometric techniques claims the rock sample they dated, from the volcano's dome, solidified somewhere between 340,000 and 2.8 million years ago. However photographic evidence and historical reports document the dome's formation during the 1980s, just ten years prior to the samples being collected. With the age of this rock known, radiometric dating therefore gets the age 99.99999% wrong. * Devils Hole Pupfish Isolated Not for 13,000 Years But for 100: Secular scientists default to knee-jerk, older-than-Bible-age dates. However, a tiny Mojave desert fish is having none of it. Rather than having been genetically isolated from other fish for 13,000 years (which would make this small school of fish older than the Earth itself), according to a paper in the journal Nature, actual measurements of mutation rates indicate that the genetic diversity of these Pupfish could have been generated in about 100 years, give or take a few. * Polystrates like Spines and Rare Schools of Fossilized Jellyfish: Previously, seven sedimentary layers in Wisconsin had been described as taking a million years to form. And because jellyfish have no skeleton, as Charles Darwin pointed out, it is rare to find them among fossils. But now, reported in the journal Geology, a school of jellyfish fossils have been found throughout those same seven layers. So, polystrate fossils that condense the time of strata deposition from eons to hours or months, include: - Jellyfish in central Wisconsin were not deposited and fossilized over a million years but during a single event quick enough to trap a whole school. (This fossil school, therefore, taken as a unit forms a polystrate fossil.) Examples are everywhere that falsify the claims of strata deposition over millions of years. - Countless trilobites buried in astounding three dimensionality around the world are meticulously recovered from limestone, much of which is claimed to have been deposited very slowly.

Listen in as Real Science Radio host Fred Williams and co-host Doug McBurney review and update some of Bob Enyart's legendary list of not so old things! From Darwin's Finches to opals forming in months to man's genetic diversity in 200 generations, to carbon 14 everywhere it's not supposed to be (including in diamonds and dinosaur bones!), scientific observations simply defy the claim that the earth is billions of years old. Real science demands the dismissal of the alleged million and billion year ages asserted by the ungodly and the foolish.   * Finches Adapt in 17 Years, Not 2.3 Million: Charles Darwin's finches are claimed to have taken 2,300,000 years to diversify from an initial species blown onto the Galapagos Islands. Yet individuals from a single finch species on a U.S. Bird Reservation in the Pacific were introduced to a group of small islands 300 miles away and in at most 17 years, like Darwin's finches, they had diversified their beaks, related muscles, and behavior to fill various ecological niches. Hear about this also at rsr.org/spetner.  * Finches Speciate in Two Generations vs Two Million Years for Darwin's Birds?  Darwin's finches on the Galapagos Islands are said to have diversified into 14 species over a period of two million years. But in 2017 the journal Science reported a newcomer to the Island which within two generations spawned a reproductively isolated new species. In another instance as documented by Lee Spetner, a hundred birds of the same finch species introduced to an island cluster a 1,000 kilometers from Galapagos diversified into species with the typical variations in beak sizes, etc. "If this diversification occurred in less than seventeen years," Dr. Spetner asks, "why did Darwin's Galapagos finches [as claimed by evolutionists] have to take two million years?" * Opals Can Form in "A Few Months" And Don't Need 100,000 Years: A leading authority on opals, Allan W. Eckert, observed that, "scientific papers and textbooks have told that the process of opal formation requires tens of thousands of years, perhaps hundreds of thousands... Not true." A 2011 peer-reviewed paper in a geology journal from Australia, where almost all the world's opal is found, reported on the: "new timetable for opal formation involving weeks to a few months and not the hundreds of thousands of years envisaged by the conventional weathering model." (And apparently, per a 2019 report from Entomology Today, opals can even form around insects!) More knowledgeable scientists resist the uncritical, group-think insistence on false super-slow formation rates (as also for manganese nodules, gold veins, stone, petroleum, canyons and gullies, and even guts, all below). Regarding opals, Darwinian bias led geologists to long ignore possible quick action, as from microbes, as a possible explanation for these mineraloids. For both in nature and in the lab, opals form rapidly, not even in 10,000 years, but in weeks. See this also from creationists by a geologist, a paleobiochemist, and a nuclear chemist. * Blue Eyes Originated Not So Long Ago: Not a million years ago, nor a hundred thousand years ago, but based on a peer-reviewed paper in Human Genetics, a press release at Science Daily reports that, "research shows that people with blue eyes have a single, common ancestor. A team at the University of Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today." * Adding the Entire Universe to our List of Not So Old Things? Based on March 2019 findings from Hubble, Nobel laureate Adam Riess of the Space Telescope Science Institute and his co-authors in the Astrophysical Journal estimate that the universe is about a billion years younger than previously thought! Then in September 2019 in the journal Science, the age dropped precipitously to as low as 11.4 billion years! Of course, these measurements also further squeeze the canonical story of the big bang chronology with its many already existing problems including the insufficient time to "evolve" distant mature galaxies, galaxy clusters, superclusters, enormous black holes, filaments, bubbles, walls, and other superstructures. So, even though the latest estimates are still absurdly too old (Google: big bang predictions, and click on the #1 ranked article, or just go on over there to rsr.org/bb), regardless, we thought we'd plop the whole universe down on our List of Not So Old Things!   * After the Soft Tissue Discoveries, NOW Dino DNA: When a North Carolina State University paleontologist took the Tyrannosaurus Rex photos to the right of original biological material, that led to the 2016 discovery of dinosaur DNA, So far researchers have also recovered dinosaur blood vessels, collagen, osteocytes, hemoglobin, red blood cells, and various proteins. As of May 2018, twenty-six scientific journals, including Nature, Science, PNAS, PLoS One, Bone, and Journal of Vertebrate Paleontology, have confirmed the discovery of biomaterial fossils from many dinosaurs! Organisms including T. Rex, hadrosaur, titanosaur, triceratops, Lufengosaur, mosasaur, and Archaeopteryx, and many others dated, allegedly, even hundreds of millions of years old, have yielded their endogenous, still-soft biological material. See the web's most complete listing of 100+ journal papers (screenshot, left) announcing these discoveries at bflist.rsr.org and see it in layman's terms at rsr.org/soft. * Rapid Stalactites, Stalagmites, Etc.: A construction worker in 1954 left a lemonade bottle in one of Australia's famous Jenolan Caves. By 2011 it had been naturally transformed into a stalagmite (below, right). Increasing scientific knowledge is arguing for rapid cave formation (see below, Nat'l Park Service shrinks Carlsbad Caverns formation estimates from 260M years, to 10M, to 2M, to it "depends"). Likewise, examples are growing of rapid formations with typical chemical make-up (see bottle, left) of classic stalactites and stalagmites including: - in Nat'l Geo the Carlsbad Caverns stalagmite that rapidly covered a bat - the tunnel stalagmites at Tennessee's Raccoon Mountain - hundreds of stalactites beneath the Lincoln Memorial - those near Gladfelter Hall at Philadelphia's Temple University (send photos to Bob@rsr.org) - hundreds of stalactites at Australia's zinc mine at Mt. Isa.   - and those beneath Melbourne's Shrine of Remembrance. * Most Human Mutations Arose in 200 Generations: From Adam until Real Science Radio, in only 200 generations! The journal Nature reports The Recent Origin of Most Human Protein-coding Variants. As summarized by geneticist co-author Joshua Akey, "Most of the mutations that we found arose in the last 200 generations or so" (the same number previously published by biblical creationists). Another 2012 paper, in the American Journal of Physical Anthropology (Eugenie Scott's own field) on High mitochondrial mutation rates, shows that one mitochondrial DNA mutation occurs every other generation, which, as creationists point out, indicates that mtEve would have lived about 200 generations ago. That's not so old! * National Geographic's Not-So-Old Hard-Rock Canyon at Mount St. Helens: As our List of Not So Old Things (this web page) reveals, by a kneejerk reaction evolutionary scientists assign ages of tens or hundreds of thousands of years (or at least just long enough to contradict Moses' chronology in Genesis.) However, with closer study, routinely, more and more old ages get revised downward to fit the world's growing scientific knowledge. So the trend is not that more information lengthens ages, but rather, as data replaces guesswork, ages tend to shrink until they are consistent with the young-earth biblical timeframe. Consistent with this observation, the May 2000 issue of National Geographic quotes the U.S. Forest Service's scientist at Mount St. Helens, Peter Frenzen, describing the canyon on the north side of the volcano. "You'd expect a hard-rock canyon to be thousands, even hundreds of thousands of years old. But this was cut in less than a decade." And as for the volcano itself, while again, the kneejerk reaction of old-earthers would be to claim that most geologic features are hundreds of thousands or millions of years old, the atheistic National Geographic magazine acknowledges from the evidence that Mount St. Helens, the volcanic mount, is only about 4,000 years old! See below and more at rsr.org/mount-st-helens. * Mount St. Helens Dome Ten Years Old not 1.7 Million: Geochron Laboratories of Cambridge, Mass., using potassium-argon and other radiometric techniques claims the rock sample they dated, from the volcano's dome, solidified somewhere between 340,000 and 2.8 million years ago. However photographic evidence and historical reports document the dome's formation during the 1980s, just ten years prior to the samples being collected. With the age of this rock known, radiometric dating therefore gets the age 99.99999% wrong. * Devils Hole Pupfish Isolated Not for 13,000 Years But for 100: Secular scientists default to knee-jerk, older-than-Bible-age dates. However, a tiny Mojave desert fish is having none of it. Rather than having been genetically isolated from other fish for 13,000 years (which would make this small school of fish older than the Earth itself), according to a paper in the journal Nature, actual measurements of mutation rates indicate that the genetic diversity of these Pupfish could have been generated in about 100 years, give or take a few. * Polystrates like Spines and Rare Schools of Fossilized Jellyfish: Previously, seven sedimentary layers in Wisconsin had been described as taking a million years to form. And because jellyfish have no skeleton, as Charles Darwin pointed out, it is rare to find them among fossils. But now, reported in the journal Geology, a school of jellyfish fossils have been found throughout those same seven layers. So, polystrate fossils that condense the time of strata deposition from eons to hours or months, include: - Jellyfish in central Wisconsin were not deposited and fossilized over a million years but during a single event quick enough to trap a whole school. (This fossil school, therefore, taken as a unit forms a polystrate fossil.) Examples are everywhere that falsify the claims of strata deposition over millions of years. - Countless trilobites buried in astounding three dimensionality around the world are meticulously recovered from limestone, much of which is claimed to have been deposited very slowly. Contrariwise, because these specimens were buried rapidly in quickly laid down sediments, they show no evidence of greater erosion on their upper parts as compared to their lower parts. - The delicacy of radiating spine polystrates, like tadpole and jellyfish fossils, especially clearly demonstrate the rapidity of such strata deposition. - A second school of jellyfish, even though they rarely fossilized, exists in another locale with jellyfish fossils in multiple layers, in Australia's Brockman Iron Formation, constraining there too the rate of strata deposition. By the way, jellyfish are an example of evolution's big squeeze. Like galaxies e

A tree has evolved to attract lightning strikes — to eliminate the competitionScientists working in Panama noticed that a particular tropical tree species was frequently struck by lightning, but was infrequently killed by the strikes. Forest ecologist Evan Gora found that Dipteryx oleifera trees were often the last ones standing after a lightning strike, which can kill over 100 trees with a single bolt. His team discovered the giant trees were more electrically conductive than other species, which allows them to not only survive strikes, but also channel lightning into parasitic vines and competing trees around them. The research was published in the journal New Phytologist.Anti-anxiety drugs we pee out could be affecting wild salmonOur bodies only process some of the pharmaceuticals we take, which means when we pee, we're releasing traces of drugs into the ecosystem. A study of the impact of trace amounts of anti-anxiety drugs on juvenile salmon suggests they might become too brave for their own survival.  Jack Brand is a researcher at the Swedish University of Agricultural Sciences and led the research published in the journal Science.Fossil discovery gives new insight into the mysterious DenisovansA jawbone pulled up by fishers off the coast of Taiwan in 2008 has proven to be a unique discovery. Analysis of preserved protein in the fossil has proved it is from a male Denisovan — a mysterious species of ancient human known from only fragmentary bones and ancient DNA. This gives new insight into how widespread this mysterious branch of humanity was. The research was led by a team including Takumi Tsutaya and Enrico Cappellini at the University of Copenhagen, and published in the journal Science.Earth's inner core is a lot more dynamic and smushy than we previously thoughtScientists used to think the inner core of our planet was a solid sphere of metal, but a new study in Nature Geoscience suggests its softer outer layers shift and deform over time. The researchers used pairs of earthquakes from the same location as X-rays to peer inside Earth to gauge what the inner core is doing; much like a stop-motion film. John Vidale, from the University of Southern California, said this insight can shed light on how a planet like ours evolves. Human noise has an impact on wildlife — here are two unique examplesTraffic, aircraft, industry, construction. Our world is saturated with artificial noise. We know noise impacts us and other animals, but new research is shedding light on how past experiences factor into the ways wildlife adapt to our noise pollution. Researchers in one study in Animal Behaviour found that yellow warblers in the Galapagos Islands that live closer to traffic become aggressive when defending their territory in noisy conditions compared to birds in quieter areas. Çağlar Akçay, from Anglia Ruskin University, said the birds exposed to more traffic have learned their warning calls aren't as effective when things get too noisy; and they resort to physical violence. Another study in Current Biology shows how spiders that are exposed to loud noises construct their webs differently in ways that could affect their ability to sense vibrations from prey or a potential mate. Brandi Pessman, from the University of Nebraska-Lincoln, found that spiders tune their webs in noisy environments like a volume dial: city spiders turn their web volume down whereas country spiders turn it up.

SpaceTime Series 28 Episode 13Mysteries of Water on Mars and the Origins of Earth's MoonIn this episode of SpaceTime, we explore groundbreaking discoveries about the history of water on Mars. New research reveals thousands of mounds on the Martian northern plains, rich in clay minerals, indicating that this area was once submerged under a vast ocean. These findings, reported in Nature Geoscience, suggest that the mounds preserve a complete geological history of water on Mars, making them prime targets for future exploration missions searching for signs of past life.Could the Moon be a Piece of Earth?We also delve into a fascinating study proposing that the Moon could have formed from material ejected from the Earth's mantle rather than from the impact of a Mars-sized body, as previously thought. This new hypothesis, based on isotopic similarities between Earth and Moon samples, offers fresh insights into the origins of our lunar companion and the potential pathways for water to have reached Earth.Establishing a Permanent Presence on the MoonAdditionally, we discuss the challenges and innovations required to establish a permanent human presence on the Moon as part of NASA's Artemis program.

SpaceTime Series 28 Episode 06Formation of Pluto-Charon Binary SystemA new study reveals that the formation of the Pluto-Charon dwarf planet binary system may mirror that of the Earth-Moon system. The research, published in Nature Geoscience, suggests that both systems feature a secondary body significantly large in comparison to the primary, unlike other moons in our solar system. The findings could explain Pluto's active geology and potential subsurface ocean, highlighting the significance of giant impacts in shaping planetary bodies.BepiColombo's Final Mercury FlybyThe BepiColombo spacecraft has completed its final close flyby of Mercury, passing just 295 kilometres above the planet's surface. This manoeuvre marks the last gravity assist required for the joint ESA and JAXA mission before it enters Mercury's orbit in late 2026. The mission aims to study Mercury's magnetic field, surface composition, and interaction with the solar wind, enhancing our understanding of planets close to their host stars.Astronomy Highlights for 20252025 promises exciting astronomical events, with the Sun's solar cycle nearing its peak.

Des planétologues de l'université de l'Arizona viennent de trouver une explication pour la formation du couple Pluton-Charon : Pluton aurait capturé Charon après que les deux planètes naines sont entrées en collision « douce », ce nouveau processus est appelé par les auteurs « kiss-and-capture », ils publient leur étude dans Nature Geoscience. Source Capture of an ancient Charon around PlutoAdeene Denton et al.Nature Geoscience (6 january 2025)https://doi.org/10.1038/s41561-024-01612-0 Illustrations Simulation de la collision Pluton-Charon (Denton et al. Adeene Denton

Billions of years ago, in the frigid outer reaches of our solar system, two icy worlds collided. Rather than destroying each other in a cosmic catastrophe, they spun together like a celestial snowman, finally separating while remaining forever linked in orbit. This is how Pluto and its largest moon, Charon, originated, according to a new University of Arizona study that challenges decades of scientific assumptions. The formation of Pluto and its largest moon A study led by Adeene Denton, a NASA postdoctoral fellow who conducted the research at the U of A Lunar and Planetary Laboratory, has revealed this unexpected "kiss and capture" mechanism, which could help scientists better understand how planetary bodies form and evolve. By considering something planetary scientists had overlooked over decades - the structural strength of cold, icy worlds - researchers have discovered an entirely new type of cosmic collision. The findings were published in the journal Nature Geoscience. For decades, scientists have theorized that Pluto's unusually large moon Charon formed through a process similar to Earth's moon - a massive collision followed by the stretching and deformation of fluid-like bodies, Denton said. This model worked well for the Earth-moon system, where the intense heat and larger masses involved meant the colliding bodies behaved more like fluids. However, when applied to the smaller, colder Pluto-Charon system, this approach overlooked a crucial factor: the structural integrity of rock and ice. "Pluto and Charon are different - they're smaller, colder and made primarily of rock and ice. When we accounted for the actual strength of these materials, we discovered something completely unexpected," Denton said. Using advanced impact simulations on the U of A's high-performance computing cluster, the research team found that instead of stretching like silly putty during the collision, Pluto and the proto-Charon actually became temporarily stuck together, rotating as a single snowman-shaped object before separating into the binary system we observe today. A binary system occurs when two celestial bodies orbit around a common center of mass, much like two figure skaters spinning while holding hands. "Most planetary collision scenarios are classified as 'hit and run' or 'graze and merge.' What we've discovered is something entirely different - a 'kiss and capture' scenario where the bodies collide, stick together briefly and then separate while remaining gravitationally bound," said Denton. "The compelling thing about this study, is that the model parameters that work to capture Charon, end up putting it in the right orbit. You get two things right for the price of one," said senior study author Erik Asphaug, a professor in the Lunar and Planetary Laboratory. The study also suggests that both Pluto and Charon remained largely intact during their collision, with much of their original composition preserved. This challenges previous models that suggested extensive deformation and mixing during the impact, Denton said. Additionally, the collision process, including tidal friction as the bodies separated, deposited considerable internal heat into both bodies, which may provide a mechanism for Pluto to develop a subsurface ocean without requiring formation in the more radioactive very early solar system - a timing constraint that has troubled planetary scientists. The research team is already planning follow-up studies to explore several key areas. The team wants to investigate how tidal forces influenced Pluto and Charon's early evolution when they were much closer together, analyze how this formation scenario aligns with Pluto's current geological features, and examine whether similar processes could explain the formation of other binary systems. "We're particularly interested in understanding how this initial configuration affects Pluto's geological evolution," Denton said. "The heat from the impact and subsequent tidal forces cou...

SpaceTime Series 27 Episode 153*The Mysterious Origins of Martian MineralsA new study suggests that some Martian minerals may have formed in liquid carbon dioxide rather than water. While traditional views link Mars' dry river channels to past water presence, this research indicates that under ancient Martian conditions, liquid CO2 could have been a significant factor in shaping the planet's geological features. This finding, published in Nature Geoscience, adds a new layer to the ongoing debate about Mars' liquid past and its implications for the planet's habitability.*Australia's Arnhem Space Centre ShutteredEquatorial Launch Australia has announced the closure of the Arnhem Space Centre due to unresolved lease issues with the Northern Land Council.

A notícia de que a cobertura vegetal do continente antártico se acelerou a um ritmo surpreendente nas últimas décadas chama a atenção para os desequilíbrios em curso no polo sul, até então mais poupado das mudanças climáticas. O que acontece na Antártida, entretanto, tem consequências em todo o planeta – em especial para a regulação do clima e a preservação da biodiversidade marinha. Lúcia Müzell, da RFI em ParisImagens de satélite do continente gelado indicam que as superfícies rochosas da península antártica, ao norte, se tornaram 14 vezes mais verdes nos últimos 35 anos, graças à multiplicação de musgos e líquens, tipos de fungos vegetais. A ampliação das áreas verdes é um símbolo do aquecimento da temperatura na região, nos últimos 60 anos.Nas zonas mais expostas, a alta da temperatura pode atingir 0,34°C por década até o fim deste século. As conclusões dos cientistas da Universidade de Exeter foram publicadas na revista científica britânica Nature Geoscience.A proteção da "Amazônia branca", como apelidou o ativista ambiental brasileiro José Truda Palazzo, está há muito tempo no radar dos defensores de animais como baleias e focas, diretamente atingidos pela crise climática. A redução das emissões de gases de efeito estufa é fundamental para conter o aquecimento global e o derretimento do gelo no continente, mas ele lembra que a biodiversidade marinha em si é um elemento importante para o equilíbrio do clima na Terra."As baleias são a grande sentinela das mudanças que vêm ocorrendo nos oceanos em função do impacto humano. As pesquisas estão mostrando que elas são extremamente importantes no ciclo do carbono dos oceanos, não só por absorverem carbono nos corpos enormes delas, como por fazerem com que haja uma ciclagem de nutrientes capazes de ampliar a capacidade dos oceanos de absorver carbono”, salienta Palazzo, que acompanha há muitos anos as negociações internacionais sobre estes assuntos, como observador.Pesca do krill e criação de novas áreas protegidasNa próxima semana, a Convenção para os Recursos Vivos Marinhos Antárticos volta a se reunir e vai discutir duas pautas prioritárias para a preservação dos seus ecossistemas: a criação de novas áreas protegidas na península antártica e a maior regulação da pesca do krill, crustáceo que se encontra na base da cadeia alimentar na região e que é, ele próprio, uma fonte natural de absorção de CO2.A Rússia e a China têm barrado avanços nestes dois temas. "A frota pesqueira global da China também está se beneficiando do crescimento da pesca antártica, principalmente do krill, mas a China tem se mostrado mais aberta ao diálogo do que a Rússia. Nós esperamos que o Brasil possa envolver os nossos atores políticos, inclusive o presidente Lula, e construir um protagonismo climático voltado também para a conservação da Antártida, a partir das parcerias que mantêm com esses dois países”, indica o ambientalista.“A proteção da Antártida é a nova fronteira importante da proteção das nossas baleias e do ambiente marinho no Brasil, já que os mares austrais se conectam com o brasileiro e o alimentam", salienta Truda Palazzo.Diminuição das placas de geloPela sua posição geográfica e a rotação da Terra, a Antártida até então era mais protegida dos impactos da mudança do clima do que o polo norte, onde seus efeitos são sentidos a uma velocidade seis vezes superior ao restante do mundo. Entretanto, nos últimos anos e em especial desde 2023, as medições das placas de gelo apontam um fenômeno preocupante: dois anos consecutivos de redução surpreendente das suas extensões, que chegou a 3 milhões de quilômetros quadrados a menos de gelo, em pleno inverno austral.“Há fenômenos cruzados entre a atmosfera, o gelo e o oceano. Os três evoluem ao mesmo tempo e não sabemos ainda qual está causando o quê. Parece haver mudanças na estrutura vertical dos oceanos, ou seja, nos movimentos ascendentes e descendentes embaixo das camadas de gelo. Essa alteração poderia explicar um excesso de calor vindo do oceano em direção ao gelo, que está sendo bastante impactado desde 2016”, ressalta Martin Vancoppenolle, pesquisador do Laboratório de Oceanografia e do Clima junto ao respeitado Centro National de Pesquisas Científicas (CNRS), onde é especializado nas interações entre o gelo, o oceano e o clima.“Várias pistas estão sendo consideradas para explicar essa redução recente. A da nossa equipe é que as placas estão ficando mais finas, o que leva ao seu derretimento mais intenso e mais precoce", diz o cientista.Importância do geloO continente gelado modifica o balanço energético do planeta, ao refletir os raios solares e, assim, contribuir para limitar o aquecimento da Terra. Os ciclos de formação e derretimento das placas de gelo também são essenciais para a circulação oceânica, outro componente do clima terrestre.A comunidade científica ainda não dispõe de dados suficientes para atribuir a redução recente das placas de gelo às mudanças climáticas – a extensão delas sempre foi variável.“O derretimento do gelo não é irreversível, até que se prove o contrário. Se voltarmos a níveis de CO2 na atmosfera abaixo dos que temos hoje, em princípio não há razão de ele não se reconstruir rapidamente, porque ele tem no máximo alguns anos de idade, ou seja, é relativamente fácil para ele se recompor, à condição que faça suficientemente frio. Ele é muito diferente das calotas continentais, que precisam de dezenas de milhares de anos para se construir", explica Vancoppenolle.Uma das principais funções das placas de gelo é justamente proteger as calotas polares, formadas por água doce e cujo derretimento causam a elevação do nível do mar.

SpaceTime Series 27 Episode 115*How Black Holes Eat StarsAstronomers have developed a groundbreaking computer simulation detailing how supermassive black holes at the centres of galaxies can rip apart and consume entire stars. The study, published in the Astrophysical Journal Letters, provides new insights into the mysterious optical and ultraviolet emissions observed during these catastrophic events. Lead author Daniel Price from Monash University explains that the simulation captures the full evolution of the debris from a star being tidally disrupted by a black hole.*New Revelations About Earth's MantleA new study reveals that the chemical composition of the Earth's mantle is uniform globally and only changes as it passes through different layers of crust closer to the planet's surface. Reported in the journal Nature Geoscience, the findings suggest that lavas from volcanic hotspots around the world likely originate from a worldwide uniform reservoir in the Earth's mantle.*Water More Widespread on the Moon Than Previously ThoughtNew maps from both the near and far sides of the Moon show that the lunar surface contains vast amounts of water, mostly locked in the lunar regolith. The findings, published in the Planetary Science Journal, suggest multiple sources of water and hydroxyl in sunlit rocks and soils, including water-rich rocks excavated by meteor impacts at all lunar latitudes.www.spacetimewithstuartgary.comwww.bitesz.comThis week's guests include: Professor Daniel Price from Monash University

Earthquakes create a spark in quartz that can form massive gold nuggetsScientists have figured out why up to 75 per cent of all the gold ever mined forms inside quartz in areas with a long history of earthquakes. Chris Voisey, a Canadian geologist at Monash University in Australia, said he was trying to solve how gold arose inside quartz. In his study in the journal Nature Geoscience, he found that earthquake stress on quartz crystals generates an electrical voltage that causes dissolved gold to precipitate into a solid that can grow into the largest nuggets ever found.Ice Age Teens went through puberty just like today's kidsA new analysis of the bones of teenagers from 25,000 years ago shows they experienced puberty in much the same way as teens today. An international team of researchers including Paleolithic archaeologist April Nowell analyzed the bones of 13 teens found across Europe, and by looking at particular markers in the bones, they were able to see which stage of puberty the teens were in when they died. The researchers could not only infer things like whether their voices were breaking, but by doing muscle analysis, they found that the teens were healthy and active, and likely involved in hunting and fishing. The research was published in the Journal of Human Evolution.Grey sharks are abandoning warming coral reefs in the Indian OceanThe grey shark in the Indian Ocean uses beautiful coral reefs as a home base, returning each day after a night of fishing. But lately the sharks have been staying away for longer periods of time, up to 16 months. Dr. Michael Willamson, a research scientist at the Zoological Society of London, found that climate change is stressing the reefs. The sharks seek out cooler but potentially more dangerous waters. Venturing away from the protected reef area leaves them more vulnerable to illegal shark fishing. The paper was published in the journal Communications BiologyA cosmic collision 9 billion years ago could be the origin of he supermassive black hole at the centre of our galaxy Using data from The Event Horizon Telescope, Dr. Yihan Wang worked with Dr. Bing Zhang at the Nevada Institute of Astrophysics to study the origins of the supermassive black hole at the centre of our galaxy. From the EHT image of the Sagittarius A* Dr. Wang and his team made an accretion model and saw that it spins very fast and that the spinning is misaligned. They believe it may have been made by merging with another supermassive black hole. about 9 billion years ago. Their paper was published in Nature Astronomy.Astronaut Roberta Bondar gives a bird's eye view of migration 32 years after she flew on the space shuttle, Roberta Bondar is still showing us what the Earth looks like from space — and from closer to the ground. Dr. Bondar trained as a wildlife photographer after her astronaut career. For a new project collected photos from space, from airplanes and helicopters, and from the ground, to bring a new perspective on the migration of two important bird species, the threatened lesser Flamingo and the endangered Whooping Crane. The book is called Space for Birds: Patterns and Parallels of Beauty and Flight.

1. Concarneau: visite de la plus vieille station marine au monde encore en activité Sarah Dirren sʹest rendue dans le Finistère en Bretagne, en France, pour visiter la plus ancienne station de recherche marine encore en activité dans le monde. Outre ses activités de recherche depuis son ouverture en 1859, la station fait partie du Musée national d'histoire naturelle et sert d'espace pédagogique où le public peut explorer la faune marine de la région. Grâce à des installations comme le Marinarium, les visiteurs et visiteuses partent à la découverte de la diversité des espèces marines, des méduses aux homards bleus, en passant par les coraux et les cultures de plancton. Découverte de ce lieu magique avec Stéphanie Massé, responsable dʹexploitation à la Station marine de Concarneau. 2. Quand les volcans de Mars se couvrent dʹun petit givre matinal Une équipe internationale de chercheurs, dirigée par l'Université de Berne (UNIBE), a fait une découverte surprenante sur Mars: une fine couche de givre au sommet des volcans martiens, les plus hautes montagnes de notre système solaire. Cette glace, visible uniquement au lever du jour, a pu être observée grâce à des milliers de photos en couleurs à haute résolution capturées par la caméra CaSSIS (Color and Stereo Surface Imaging System) à bord de la sonde ExoMars Trace Gas Orbiter (TGO) de l'Agence spatiale européenne (ESA). Les images montrent clairement du givre dans les zones moins exposées au soleil, comme le bord nord de l'Olympus Mons, un volcan qui s'élève à 26 kilomètres au-dessus des plaines environnantes. Un phénomène difficile à expliquer pour les Terriens, puisque ces volcans se trouvent à des latitudes basses, près de l'équateur martien, où normalement la température devrait être plus élevée. Cécile Guérin éclaircit le sujet en compagnie dʹAntoine Pommerol, planétologue au Département de recherche spatiale et des sciences planétaires à lʹUNIBE, co-auteur de cette étude parue dans Nature Geoscience (10.06.24). 3. La preuve par le slip: deux mois plus tard, les résultats de lʹexpérience En avril 2024, lʹOffice fédéral de lʹenvironnement (OFEV) lançait une action de science participative à la population dénommée "La preuve par le slip". Les 20 et 21 avril, les personnes intéressées pouvaient découvrir lʹétat de santé et le degré de vitalité du sol de leur terrain via une technique toute particulière. Pour participer à lʹexpérience, il suffisait dʹenterrer des sous-vêtements dans son jardin et dʹattendre deux mois. Deux mois plus tard, nous y sommes, il est lʹheure dʹaller récolter petites culottes et autres caleçons colorés pour voir dans quel état de dégradation ils se trouvent. Pour rappel: moins il reste de sous-vêtement, plus le sol est sain! Explications avec Elena Havlicek, pédologue, docteure en science du sol à lʹOFEV. Un sujet de Sarah Dirren. À réécouter: "La preuve par le slip! Ou quel est lʹétat de santé de notre sol" (CQFD, 17.04.24). 4.

Killer whales are likely ramming boats because they're bored and having funSeveral years ago a small population of killer whales living off the coast of Spain began attacking boats, particularly sailboats, damaging some severely and even sinking a handful. While social media speculation has suggested whale rage as a cause, an international team of killer whale experts recently published a report suggesting the behaviour is not aggression, but is instead an example of these giant social creatures just playing and having fun with a toy. We speak with two contributors to the report: John Ford, research scientist emeritus at the Pacific Biological Station with Fisheries & Oceans Canada, and Renaud de Stephanis, the president of Spanish conservation group CIRCE.4,000-year-old Egyptian skull shows signs of possible surgery for brain cancerResearchers studying the history of cancer in human history recently hit the jackpot. In a collection of human remains at the University of Cambridge they found two skulls from Egypt, both thousands of years old, that show signs of advanced cancer. One of those skulls bore cut marks around the lesions. Lead study author and University of Santiago de Compostela professor Edgard Camarós said that regardless of whether these cuts were made as attempts at treatment or a post-mortem investigation, they show off the sophisticated medical knowledge of ancient Egyptians — and can also help better understand the evolution of cancer.This study was published in Frontiers in Medicine.Gorillas' tiny penises and low sperm count can help us understand infertility in humansGorillas are the biggest of the great apes, but their reproductive anatomy is diminutive. The males have small penises and testes, and low sperm quality. A new genetic analysis, published in the scientific journal eLife, identified the mutations that are responsible for male gorillas' peculiar fertility. Vincent Lynch, an associate professor of biological sciences at the State University of New York at Buffalo, said these findings can help us better understand the genes responsible for lower sperm quality in humans.1Illuminating plumes of hot magma in the Earth's mantle with earthquake seismic dataTo understand the source of the magma fueling volcanic eruptions, scientists are using another significant geological event: earthquakes. The seismic waves that earthquakes send through our planet can shine a light on the chimneys of magma that connect the core of the Earth through the mantle to the surface. Karin Sigloch, a professor of geophysics at CNRS — France's National Centre for Scientific Research, is part of an international effort to deploy seismic sensors throughout the oceans to illuminate the mantle plumes. Their research from recent observations in the Indian Ocean around Réunion Island was in Nature Geoscience. It's intelligence all the way down: How cells, tissues and organs have their own smartsWe tend to think of collective intelligence as something we see among animals that work cooperatively to solve problems, like in an ant colony, a school of fish or flock of birds. But biologist Michael Levin, from Harvard and Tufts' universities, thinks collective intelligence also extends to functions within the cell, all the way up to networks of cells, tissues and even organs. He suggests evolution has granted simpler biological layers in living systems the ability to flexibly solve problems. In a recent paper in Communications Biology, he argues we can harness these lower level problem-solving capabilities to make significant advances in regenerative medicine, and treating aging and disease.  

(Conversation recorded on April 23rd, 2024)   Show Summary:  On this episode, Nate is joined by climate physicist Levke Caesar for a comprehensive overview of the Atlantic Meridional Overturning Circulation (AMOC) and its connections to broader planetary systems. Amid a complex and heavily interconnected climate system, the AMOC is a powerful force for regulating temperature between the Northern and Southern Hemispheres along the Atlantic Ocean - yet it's estimated to have slowed down by about 15% over the last few decades. What are the possible domino effects of this slowing oceanic powerhouse at a regional and global scale? How well do we understand what drives the AMOC, its cyclical patterns, and connections with other currents? More importantly, how does the AMOC interact with other biospheric mechanisms that have shaped our stable, life-supporting planetary home? About Levke Caesar: Levke Caesar is a climate physicist at the Potsdam Institute for Climate Impact Research, mainly known for her studies on the Atlantic Meridional Overturning Circulation (AMOC) and its pivotal role in the climate system. Her research primarily focuses on the past, present, and future evolution of the AMOC and its intricate interactions within the North Atlantic region. Caesar's seminal work on the historical evolution of the AMOC has been featured in prestigious journals such as Nature and Nature Geoscience, garnering hundreds of citations. Since October 2023, she has assumed the role of scientific lead for the newly launched Planetary Boundary Science Initiative (PBScience) at PIK.

-- Finches Diversify in Decades, Opals Form in Months,  Man's Genetic Diversity in 200 Generations, C-14 Everywhere: Real Science Radio hosts Bob Enyart and Fred Williams present their classic program that led to the audience-favorites rsr.org/list-shows! See below and hear on today's radio program our list of Not So Old and Not So Slow Things! From opals forming in months to man's genetic diversity in 200 generations, and with carbon 14 everywhere it's not supposed to be (including in diamonds and dinosaur bones!), scientific observations fill the guys' most traditional list challenging those who claim that the earth is billions of years old. Many of these scientific finds demand a re-evaluation of supposed million and billion-year ages. * Finches Adapt in 17 Years, Not 2.3 Million: Charles Darwin's finches are claimed to have taken 2,300,000 years to diversify from an initial species blown onto the Galapagos Islands. Yet individuals from a single finch species on a U.S. Bird Reservation in the Pacific were introduced to a group of small islands 300 miles away and in at most 17 years, like Darwin's finches, they had diversified their beaks, related muscles, and behavior to fill various ecological niches. Hear about this also at rsr.org/spetner. * Opals Can Form in "A Few Months" And Don't Need 100,000 Years: A leading authority on opals, Allan W. Eckert, observed that, "scientific papers and textbooks have told that the process of opal formation requires tens of thousands of years, perhaps hundreds of thousands... Not true." A 2011 peer-reviewed paper in a geology journal from Australia, where almost all the world's opal is found, reported on the: "new timetable for opal formation involving weeks to a few months and not the hundreds of thousands of years envisaged by the conventional weathering model." (And apparently, per a 2019 report from Entomology Today, opals can even form around insects!) More knowledgeable scientists resist the uncritical, group-think insistence on false super-slow formation rates (as also for manganese nodules, gold veins, stone, petroleum, canyons and gullies, and even guts, all below). Regarding opals, Darwinian bias led geologists to long ignore possible quick action, as from microbes, as a possible explanation for these mineraloids. For both in nature and in the lab, opals form rapidly, not even in 10,000 years, but in weeks. See this also from creationists by a geologist, a paleobiochemist, and a nuclear chemist. * Finches Speciate in Two Generations vs Two Million Years for Darwin's Birds?  Darwin's finches on the Galapagos Islands are said to have diversified into 14 species over a period of two million years. But in 2017 the journal Science reported a newcomer to the Island which within two generations spawned a reproductively isolated new species. In another instance as documented by Lee Spetner, a hundred birds of the same finch species introduced to an island cluster a 1,000 kilometers from Galapagos diversified into species with the typical variations in beak sizes, etc. "If this diversification occurred in less than seventeen years," Dr. Spetner asks, "why did Darwin's Galapagos finches [as claimed by evolutionists] have to take two million years?" * Blue Eyes Originated Not So Long Ago: Not a million years ago, nor a hundred thousand years ago, but based on a peer-reviewed paper in Human Genetics, a press release at Science Daily reports that, "research shows that people with blue eyes have a single, common ancestor. A team at the University of Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of the eye colour of all blue-eyed humans alive on the planet today." * Adding the Entire Universe to our List of Not So Old Things? Based on March 2019 findings from Hubble, Nobel laureate Adam Riess of the Space Telescope Science Institute and his co-authors in the Astrophysical Journal estimate that the universe is about a billion years younger than previously thought! Then in September 2019 in the journal Science, the age dropped precipitiously to as low as 11.4 billion years! Of course, these measurements also further squeeze the canonical story of the big bang chronology with its many already existing problems including the insufficient time to "evolve" distant mature galaxies, galaxy clusters, superclusters, enormous black holes, filaments, bubbles, walls, and other superstructures. So, even though the latest estimates are still absurdly too old (Google: big bang predictions, and click on the #1 ranked article, or just go on over there to rsr.org/bb), regardless, we thought we'd plop the whole universe down on our List of Not So Old Things!   * After the Soft Tissue Discoveries, NOW Dino DNA: When a North Carolina State University paleontologist took the Tyrannosaurus Rex photos to the right of original biological material, that led to the 2016 discovery of dinosaur DNA, So far researchers have also recovered dinosaur blood vessels, collagen, osteocytes, hemoglobin, red blood cells, and various proteins. As of May 2018, twenty-six scientific journals, including Nature, Science, PNAS, PLoS One, Bone, and Journal of Vertebrate Paleontology, have confirmed the discovery of biomaterial fossils from many dinosaurs! Organisms including T. Rex, hadrosaur, titanosaur, triceratops, Lufengosaur, mosasaur, and Archaeopteryx, and many others dated, allegedly, even hundreds of millions of years old, have yielded their endogenous, still-soft biological material. See the web's most complete listing of 100+ journal papers (screenshot, left) announcing these discoveries at bflist.rsr.org and see it in layman's terms at rsr.org/soft. * Rapid Stalactites, Stalagmites, Etc.: A construction worker in 1954 left a lemonade bottle in one of Australia's famous Jenolan Caves. By 2011 it had been naturally transformed into a stalagmite (below, right). Increasing scientific knowledge is arguing for rapid cave formation (see below, Nat'l Park Service shrinks Carlsbad Caverns formation estimates from 260M years, to 10M, to 2M, to it "depends"). Likewise, examples are growing of rapid formations with typical chemical make-up (see bottle, left) of classic stalactites and stalagmites including:- in Nat'l Geo the Carlsbad Caverns stalagmite that rapidly covered a bat - the tunnel stalagmites at Tennessee's Raccoon Mountain - hundreds of stalactites beneath the Lincoln Memorial - those near Gladfelter Hall at Philadelphia's Temple University (send photos to Bob@rsr.org) - hundreds of stalactites at Australia's zinc mine at Mt. Isa.   - and those beneath Melbourne's Shrine of Remembrance. * Most Human Mutations Arose in 200 Generations: From Adam until Real Science Radio, in only 200 generations! The journal Nature reports The Recent Origin of Most Human Protein-coding Variants. As summarized by geneticist co-author Joshua Akey, "Most of the mutations that we found arose in the last 200 generations or so" (the same number previously published by biblical creationists). Another 2012 paper, in the American Journal of Physical Anthropology (Eugenie Scott's own field) on High mitochondrial mutation rates, shows that one mitochondrial DNA mutation occurs every other generation, which, as creationists point out, indicates that mtEve would have lived about 200 generations ago. That's not so old! * National Geographic's Not-So-Old Hard-Rock Canyon at Mount St. Helens: As our List of Not So Old Things (this web page) reveals, by a kneejerk reaction evolutionary scientists assign ages of tens or hundreds of thousands of years (or at least just long enough to contradict Moses' chronology in Genesis.) However, with closer study, routinely, more and more old ages get revised downward to fit the world's growing scientific knowledge. So the trend is not that more information lengthens ages, but rather, as data replaces guesswork, ages tend to shrink until they are consistent with the young-earth biblical timeframe. Consistent with this observation, the May 2000 issue of National Geographic quotes the U.S. Forest Service's scientist at Mount St. Helens, Peter Frenzen, describing the canyon on the north side of the volcano. "You'd expect a hard-rock canyon to be thousands, even hundreds of thousands of years old. But this was cut in less than a decade." And as for the volcano itself, while again, the kneejerk reaction of old-earthers would be to claim that most geologic features are hundreds of thousands or millions of years old, the atheistic National Geographic magazine acknowledges from the evidence that Mount St. Helens, the volcanic mount, is only about 4,000 years old! See below and more at rsr.org/mount-st-helens. * Mount St. Helens Dome Ten Years Old not 1.7 Million: Geochron Laboratories of Cambridge, Mass., using potassium-argon and other radiometric techniques claims the rock sample they dated, from the volcano's dome, solidified somewhere between 340,000 and 2.8 million years ago. However photographic evidence and historical reports document the dome's formation during the 1980s, just ten years prior to the samples being collected. With the age of this rock known, radiometric dating therefore gets the age 99.99999% wrong. * Devils Hole Pupfish Isolated Not for 13,000 Years But for 100: Secular scientists default to knee-jerk, older-than-Bible-age dates. However, a tiny Mojave desert fish is having none of it. Rather than having been genetically isolated from other fish for 13,000 years (which would make this small school of fish older than the Earth itself), according to a paper in the journal Nature, actual measurements of mutation rates indicate that the genetic diversity of these Pupfish could have been generated in about 100 years, give or take a few. * Polystrates like Spines and Rare Schools of Fossilized Jellyfish: Previously, seven sedimentary layers in Wisconsin had been described as taking a million years to form. And because jellyfish have no skeleton, as Charles Darwin pointed out, it is rare to find them among fossils. But now, reported in the journal Geology, a school of jellyfish fossils have been found throughout those same seven layers. So, polystrate fossils that condense the time of strata deposition from eons to hours or months, include: - Jellyfish in central Wisconsin were not deposited and fossilized over a million years but during a single event quick enough to trap a whole school. (This fossil school, therefore, taken as a unit forms a polystrate fossil.) Examples are everywhere that falsify the claims of strata deposition over millions of years. - Countless trilobites buried in astounding three dimensionality around the world are meticulously recovered from limestone, much of which is claimed to have been deposited very slowly. Contrariwise, because these specimens were buried rapidly in quickly laid down sediments, they show no evidence of greater erosion on their upper parts as compared to their lower parts.- The delicacy of radiating spine polystrates, like tadpole and jellyfish fossils, especially clearly demonstrate the rapidity of such strata deposition. - A second school of jellyfish, even though they rarely fossilized, exists in another locale with jellyfish fossils in multiple layers, in Australia's Brockman Iron Formation, constraining there too the rate of strata deposition. By the way, jellyfish are an example of evolution's big squeeze. Like galaxies evolving too quickly, galaxy clusters, and even human feet (which, like Mummy DNA, challenge the Out of Africa paradigm), jellyfish have gotten into the act squeezing evolution's timeline, here by 200 million years when they were found in strata allegedly a half-a-billion years old. Other examples, ironically referred to as Medusoid Problematica, are even found in pre-Cambrian strata. - 171 tadpoles of the same species buried in diatoms. - Leaves buried vertically through single-celled diatoms powerfully refute the claimed super-slow deposition of diatomaceous rock. - Many fossils, including a Mesosaur, have been buried in multiple "varve" layers, which are claimed to be annual depositions, yet they show no erosional patterns that would indicate gradual burial (as they claim, absurdly, over even thousands of years). - A single whale skeleton preserved in California in dozens of layers of diatom deposits thus forming a polystrate fossil. - 40 whales buried in the desert in Chile. "What's really interesting is that this didn't just happen once," said Smithsonian evolutionist Dr. Nick Pyenson. It happened four times." Why's that? Because "the fossil site has at least four layers", to which Real Science Radio's Bob Enyart replies: "Ha ha ha ha ha ha ha ha ha ha ha", with RSR co-host Fred Williams thoughtfully adding, "Ha ha!" * Polystrate Trees: Examples abound around the world of polystrate trees:  - Yellowstone's petrified polystrate forest (with the NPS exhibit sign removed; see below) with successive layers of rootless trees demonstrating the rapid deposition of fifty layers of strata. - A similarly formed polystrate fossil forest in France demonstrating the rapid deposition of a dozen strata. - In a thousand locations including famously the Fossil Cliffs of Joggins, Nova Scotia, polystrate fossils such as trees span many strata. - These trees lack erosion: Not only should such fossils, generally speaking, not even exist, but polystrates including trees typically show no evidence of erosion increasing with height. All of this powerfully disproves the claim that the layers were deposited slowly over thousands or millions of years. In the experience of your RSR radio hosts, evolutionists commonly respond to this hard evidence with mocking. See CRSQ June 2006, ICR Impact #316, and RSR 8-11-06 at KGOV.com. * Yellowstone Petrified Trees Sign Removed: The National Park Service removed their incorrect sign (see left and more). The NPS had claimed that in dozens of different strata over a 40-square mile area, many petrified trees were still standing where they had grown. The NPS eventually removed the sign partly because those petrified trees had no root systems, which they would have had if they had grown there. Instead, the trees of this "fossil forest" have roots that are abruptly broken off two or three feet from their trunks. If these mature trees actually had been remnants of sequential forests that had grown up in strata layer on top of strata layer, 27 times on Specimen Ridge (and 50 times at Specimen Creek), such a natural history implies passage of more time than permitted by biblical chronology. So, don't trust the National Park Service on historical science because they're wrong on the age of the Earth. * Wood Petrifies Quickly: Not surprisingly, by the common evolutionary knee-jerk claim of deep time, "several researchers believe that several millions of years are necessary for the complete formation of silicified wood". Our List of Not So Old and Not So Slow Things includes the work of five Japanese scientists who proved creationist research and published their results in the peer-reviewed journal Sedimentary Geology showing that wood can and does petrify rapidly. Modern wood significantly petrified in 36 years these researchers concluded that wood buried in strata could have been petrified in "a fairly short period of time, in the order of several tens to hundreds of years." * The Scablands: The primary surface features of the Scablands, which cover thousands of square miles of eastern Washington, were long believed to have formed gradually. Yet, against the determined claims of uniformitarian geologists, there is now overwhelming evidence as presented even in a NOVA TV program that the primary features of the Scablands formed rapidly from a catastrophic breach of Lake Missoula causing a massive regional flood. Of course evolutionary geologists still argue that the landscape was formed over tens of thousands of years, now by claiming there must have been a hundred Missoula floods. However, the evidence that there was Only One Lake Missoula Flood has been powerfully reinforced by a University of Colorado Ph.D. thesis. So the Scablands itself is no longer available to old-earthers as de facto evidence for the passage of millions of years. * The Heart Mountain Detachment: in Wyoming just east of Yellowstone, this mountain did not break apart slowly by uniformitarian processes but in only about half-an-hour as widely reported including in the evolutionist LiveScience.com, "Land Speed Record: Mountain Moves 62 Miles in 30 Minutes." The evidence indicates that this mountain of rock covering 425 square miles rapidly broke into 50 pieces and slid apart over an area of more than 1,300 square miles in a biblical, not a "geological," timeframe.  * "150 Million" year-old Squid Ink Not Decomposed: This still-writable ink had dehydrated but had not decomposed! The British Geological Survey's Dr. Phil Wilby, who excavated the fossil, said, "It is difficult to imagine how you can have something as soft and sloppy as an ink sac fossilised in three dimensions, still black, and inside a rock that is 150 million years old." And the Daily Mail states that, "the black ink was of exactly the same structure as that of today's version", just desiccated. And Wilby added, "Normally you would find only the hard parts like the shell and bones fossilised but... these creatures... can be dissected as if they are living animals, you can see the muscle fibres and cells. It is difficult to imagine... The structure is similar to ink from a modern squid so we can write with it..." Why is this difficult for evolutionists to imagine? Because as Dr. Carl Wieland writes, "Chemical structures 'fall apart' all by themselves over time due to the randomizing effects of molecular motion."Decades ago Bob Enyart broadcast a geology program about Mount St. Helens' catastrophic destruction of forests and the hydraulic transportation and upright deposition of trees. Later, Bob met the chief ranger from Haleakala National Park on Hawaii's island of Maui, Mark Tanaka-Sanders. The ranger agreed to correspond with his colleague at Yellowstone to urge him to have the sign removed. Thankfully, it was then removed. (See also AIG, CMI, and all the original Yellowstone exhibit photos.) Groundbreaking research conducted by creation geologist Dr. Steve Austin in Spirit Lake after Mount St. Helens eruption provided a modern-day analog to the formation of Yellowstone fossil forest. A steam blast from that volcano blew over tens of thousands of trees leaving them without attached roots. Many thousands of those trees were floating upright in Spirit Lake, and began sinking at varying rates into rapidly and sporadically deposited sediments. Once Yellowstone's successive forest interpretation was falsified (though like with junk DNA, it's too big to fail, so many atheists and others still cling to it), the erroneous sign was removed. * Asiatic vs. European Honeybees: These two populations of bees have been separated supposedly for seven million years. A researcher decided to put the two together to see what would happen. What we should have here is a failure to communicate that would have resulted after their "language" evolved over millions of years. However, European and Asiatic honeybees are still able to communicate, putting into doubt the evolutionary claim that they were separated over "geologic periods." For more, see the Public Library of Science, Asiatic Honeybees Can Understand Dance Language of European Honeybees. (Oh yeah, and why don't fossils of poorly-formed honeycombs exist, from the millions of years before the bees and natural selection finally got the design right? Ha! Because they don't exist! :) Nautiloid proves rapid limestone formation. * Remember the Nautiloids: In the Grand Canyon there is a limestone layer averaging seven feet thick that runs the 277 miles of the canyon (and beyond) that covers hundreds of square miles and contains an average of one nautiloid fossil per square meter. Along with many other dead creatures in this one particular layer, 15% of these nautiloids were killed and then fossilized standing on their heads. Yes, vertically. They were caught in such an intense and rapid catastrophic flow that gravity was not able to cause all of their dead carcasses to fall over on their sides. Famed Mount St. Helens geologist Steve Austin is also the world's leading expert on nautiloid fossils and has worked in the canyon and presented his findings to the park's rangers at the invitation of National Park Service officials. Austin points out, as is true of many of the world's mass fossil graveyards, that this enormous nautiloid deposition provides indisputable proof of the extremely rapid formation of a significant layer of limestone near the bottom of the canyon, a layer like the others we've been told about, that allegedly formed at the bottom of a calm and placid sea with slow and gradual sedimentation. But a million nautiloids, standing on their heads, literally, would beg to differ. At our sister stie, RSR provides the relevant Geologic Society of America abstract, links, and video. *  Now It's Allegedly Two Million Year-Old Leaves: "When we started pulling leaves out of the soil, that was surreal, to know that it's millions of years old..." sur-re-al: adjective: a bizarre mix of fact and fantasy. In this case, the leaves are the facts. Earth scientists from Ohio State and the University of Minnesota say that wood and leaves they found in the Canadian Arctic are at least two million years old, and perhaps more than ten million years old, even though the leaves are just dry and crumbly and the wood still burns! * Gold Precipitates in Veins in Less than a Second: After geologists submitted for decades to the assumption that each layer of gold would deposit at the alleged super slow rates of geologic process, the journal Nature Geoscience reports that each layer of deposition can occur within a few tenths of a second. Meanwhile, at the Lihir gold deposit in Papua New Guinea, evolutionists assumed the more than 20 million ounces of gold in the Lihir reserve took millions of years to deposit, but as reported in the journal Science, geologists can now demonstrate that the deposit could have formed in thousands of years, or far more quickly! Iceland's not-so-old Surtsey Island looks ancient. * Surtsey Island, Iceland: Of the volcanic island that formed in 1963, New Scientist reported in 2007 about Surtsey that "geographers... marvel that canyons, gullies and other land features that typically take tens of thousands or millions of years to form were created in less than a decade." Yes. And Sigurdur Thorarinsson, Iceland's chief  geologist, wrote in the months after Surtsey formed, "that the time scale," he had been trained "to attach to geological developments is misleading." [For what is said to] take thousands of years... the same development may take a few weeks or even days here [including to form] a landscape... so varied and mature that it was almost beyond belief... wide sandy beaches and precipitous crags... gravel banks and lagoons, impressive cliffs… hollows, glens and soft undulating land... fractures and faultscarps, channels and screes… confounded by what met your eye... boulders worn by the surf, some of which were almost round... -Iceland's chief geologist * The Palouse River Gorge: In the southeast of Washington State, the Palouse River Gorge is one of many features formed rapidly by 500 cubic miles of water catastrophically released with the breaching of a natural dam in the Lake Missoula Flood (which gouged out the Scablands as described above). So, hard rock can be breached and eroded rapidly. * Leaf Shapes Identical for 190 Million Years?  From Berkley.edu, "Ginkgo biloba... dates back to... about 190 million years ago... fossilized leaf material from the Tertiary species Ginkgo adiantoides is considered similar or even identical to that produced by modern Ginkgo biloba trees... virtually indistinguishable..." The literature describes leaf shapes as "spectacularly diverse" sometimes within a species but especially across the plant kingdom. Because all kinds of plants survive with all kinds of different leaf shapes, the conservation of a species retaining a single shape over alleged deep time is a telling issue. Darwin's theory is undermined by the unchanging shape over millions of years of a species' leaf shape. This lack of change, stasis in what should be an easily morphable plant trait, supports the broader conclusion that chimp-like creatures did not become human beings and all the other ambitious evolutionary creation of new kinds are simply imagined. (Ginkgo adiantoides and biloba are actually the same species. Wikipedia states, "It is doubtful whether the Northern Hemisphere fossil species of Ginkgo can be reliably distinguished." For oftentimes, as documented by Dr. Carl Werner in his Evolution: The Grand Experiment series, paleontogists falsely speciate identical specimens, giving different species names, even different genus names, to the fossil and living animals that appear identical.) * Box Canyon, Idaho: Geologists now think Box Canyon in Idaho, USA, was carved by a catastrophic flood and not slowly over millions of years with 1) huge plunge pools formed by waterfalls; 2) the almost complete removal of large basalt boulders from the canyon; 3) an eroded notch on the plateau at the top of the canyon; and 4) water scour marks on the basalt plateau leading to the canyon. Scientists calculate that the flood was so large that it could have eroded the whole canyon in as little as 35 days. See the journal Science, Formation of Box Canyon, Idaho, by Megaflood, and the Journal of Creation, and Creation Magazine. * Manganese Nodules Rapid Formation: Allegedly, as claimed at the Wikipedia entry from 2005 through 2021: "Nodule growth is one of the slowest of all geological phenomena – in the order of a centimeter over several million years." Wow, that would be slow! And a Texas A&M Marine Sciences technical slide presentation says, “They grow very slowly (mm/million years) and can be tens of millions of years old", with RWU's oceanography textbook also putting it at "0.001 mm per thousand years." But according to a World Almanac documentary they have formed "around beer cans," said marine geologist Dr. John Yates in the 1997 video Universe Beneath the Sea: The Next Frontier. There are also reports of manganese nodules forming around ships sunk in the First World War. See more at at youngearth.com, at TOL, in the print edition of the Journal of Creation, and in this typical forum discussion with atheists (at the Chicago Cubs forum no less :). * "6,000 year-old" Mitochondrial Eve: As the Bible calls "Eve... the mother of all living" (Gen. 3:20), genetic researchers have named the one woman from whom all humans have descended "Mitochondrial Eve." But in a scientific attempt to date her existence, they openly admit that they included chimpanzee DNA in their analysis in order to get what they viewed as a reasonably old date of 200,000 years ago (which is still surprisingly recent from their perspective, but old enough not to strain Darwinian theory too much). But then as widely reported including by Science magazine, when they dropped the chimp data and used only actual human mutation rates, that process determined that Eve lived only six thousand years ago! In Ann Gibbon's Science article, "Calibrating the Mitochondrial Clock," rather than again using circular reasoning by assuming their conclusion (that humans evolved from ape-like creatures), they performed their calculations using actual measured mutation rates. This peer-reviewed journal then reported that if these rates have been constant, "mitochondrial Eve… would be a mere 6000 years old." See also the journal Nature and creation.com's "A shrinking date for Eve," and Walt Brown's assessment. Expectedly though, evolutionists have found a way to reject their own unbiased finding (the conclusion contrary to their self-interest) by returning to their original method of using circular reasoning, as reported in the American Journal of Human Genetics, "calibrating against recent evidence for the divergence time of humans and chimpanzees,"  to reset their mitochondrial clock back to 200,000 years. * Even Younger Y-Chromosomal Adam: (Although he should be called, "Y-Chromosomal Noah.") While we inherit our mtDNA only from our mothers, only men have a Y chromosome (which incidentally genetically disproves the claim that the fetus is "part of the woman's body," since the little boy's y chromosome could never be part of mom's body). Based on documented mutation rates on and the extraordinary lack of mutational differences in this specifically male DNA, the Y-chromosomal Adam would have lived only a few thousand years ago! (He's significantly younger than mtEve because of the genetic bottleneck of the global flood.) Yet while the Darwinian camp wrongly claimed for decades that humans were 98% genetically similar to chimps, secular scientists today, using the same type of calculation only more accurately, have unintentionally documented that chimps are about as far genetically from what makes a human being a male, as mankind itself is from sponges! Geneticists have found now that sponges are 70% the same as humans genetically, and separately, that human and chimp Y chromosomes are  "horrendously" 30%

All plants, including algae and cyanobacteria, carry out photosynthesis. During the process of photosynthesis, plants remove carbon dioxide from the air and release oxygen to the air.  As a result, plants play a crucial role in the fight against climate change.  According to a new study recently published in the journal Nature Geoscience, mosses – […]

Predecir el clima futuro es un reto impresionante que los científicos afrontan utilizando modelos teóricos elaborados y ajustados con datos reales presentes y pasados. Durante las décadas recientes, gracias a los grandes avances de la instrumentación terrestre y espacial, se tiene datos en abundancia, pero no así del clima de tiempos más remotos. Una forma de conocer cómo se comportó el clima en el pasado consiste en analizar los restos acumulados en los sedimentos de los lagos. En un reciente trabajo, publicado en Nature Geoscience, la investigadora y profesora de la Universidad Royal Holloway de Londres, Celia Martín Puertas y sus colegas muestran los resultados del estudio de los registros del clima almacenados durante 10.500 años en el fondo de un pequeño lago en el centro este de Inglaterra, de nombre Diss Mere.

Esta semana ha saltado a la palestra un resultado científico según el cual el núcleo terrestre "se había parado". Esta afirmación, quizá porque tenemos muy presentes algunas películas de ciencia-ficción, ha generado cierto revuelo; al fin y al cabo, si el núcleo se parara ¿no sería malo para nosotros? ¿No se generarían todo tipo de anomalías en nuestro planeta? Vamos a dedicar unos minutos a explicar qué es realmente lo que se ha descubierto en un artículo que acaba de aparecer en la revista Nature Geoscience, y alerta de espoilers: no es que se haya parado el núcleo. Os explicamos cómo es la estructura interna de nuestro planeta y por qué eso da cierta libertad a la rotación del núcleo, y os contamos cuáles son los efectos reales del nuevo descubrimiento. Si a alguno os interesa leer el artículo científico, es "Multidecadal variation of the Earth’s inner-core rotation", de Yi Yang y Xiaodong Song. Lo tenéis en este enlace: https://www.nature.com/articles/s41561-022-01112-z Si os interesa el interior de nuestro planeta y cómo eso afecta al campo magnético o a la duración del día os recomiendo que repaséis los episodios s08e31 y s01e14.

What's Behind The Strange Slowing Of The Earth's Core? Even though some days feel more chaotic than others, the rotation of the surface of the planet proceeds at a pretty constant rate—about one full rotation every 24 hours. But the rotational speed of the inner core is less stable, and has been known to shift over time. Now, researchers are reporting in the journal Nature Geoscience that according to seismic data, the Earth's inner core may have recently paused its rotation, and could even go on to reverse direction relative to the rest of the planet. Tim Revell, deputy United States editor of New Scientist, joins SciFri producer Kathleen Davis to talk about the shift in rotation and other stories from the week in science, including shared language characteristics between humans and wild apes, and a wolf population that has started to enjoy snacking on sea otters. They'll also talk about an ancient Egyptian mummy with a heart of gold, research into why some mushrooms glow in the dark, and a tiny robot with morphing liquid metal capabilities straight out of Hollywood.   Here's What We Know About Long COVID, Three Years Later Just a few months into the pandemic, it became clear that in some people, the SARS-CoV-2 virus caused a cascade of symptoms for months after their initial infections. These lingering effects are now commonly referred to as Long COVID. And as long as the pandemic barrels on, the population of Long COVID patients will continue to grow. Over the past three years, researchers have closely studied these symptoms, seeking to better understand its underlying causes and improve treatment. Guest host Maddie Sofia talks with Hannah Davis, co-founder of the Patient-Led Research Collaborative and co-author of a recently published comprehensive review on the state of Long COVID research, and Dr. Bhupesh Prusty, principal investigator at the Institute for Virology and Immmunobiology at the University of Würzburg in Germany.   Meet The Art Sleuths Using Science To Find Frauds At the end of last year, a big case was decided in the world of art crime. Qatari Sheikh Hamad al Thani won a case against his former art dealer, after nearly $5 million dollars worth of purchased ancient artifacts were all determined to be fake. Among the artifacts was a Hari Hara sandstone statue purported to be from 7th century Vietnam. In reality, the piece was made in 2013. Art experts say forged antiquities are extremely common in museums and private art collections: Former director of the Metropolitan Museum of Art Thomas Hoving estimated 40% of artworks for sale at any given time were fake. The task of determining what art is real and what art is fake falls to scientists, who use tools like X-rays and carbon dating to get accurate readings of time and place of origin for artifacts. Joining guest host Kathleen Davis to talk about this are Erin Thompson, art crime professor at the City University of New York, and Patrick Degryse, professor of archeometry at the Katholieke Universiteit Leuven in Belgium. Transcripts for each segment will be available the week after the show airs on sciencefriday.com.  

Uh, Earth's Inner Core Just Stopped SpinningEarth's inner core's spin has slowed and “paused.”Scientists believe this happens roughly every seven decades as the core will then start spinning a different direction.A new study says there's a direct connection between the inner core's spin and life on Earth's surface.Earth's inner core stopped spinning. But don't fret, it appears this happens from time to time, say every seven decades or so.A new study published in Nature Geoscience by geophysicists Yi Yang and Xiadong Song of Peking University in Beijing explored the nature of movement of Earth's inner core, largely made up of iron and molten liquids. They found the inner core's movement recently reduced enough they consider it “paused,” all part of what “seems to be associated with a gradual turning back of the inner core as a part of an approximately seven-decade oscillation.”The last turning point was in the early 1970s.Our understanding of Earth's inner core doesn't have a strong history. Ancient days, of course, had folks believing in a hollow core. Then came the understanding of iron and a molten mixture making up Earth's middle, coupled with the theory of spinning happening separate from the rest of Earth. Song confirmed the spinning theory in 1996.We don't quite know the speed of spinning, but it appears that may be because the inner core remains in a constant state of flux and switches directions roughly every seven decades thanks to electromagnetic imbalances and gravitational forces.The new study further tracked seismic waves through the core to see how they played out on the other side of Earth. “This globally consistent pattern suggests that inner-core rotation has recently paused,” the study says.With the spin changing throughout the decades, the authors believe there's an interplay between the spinning of the core and Earth's mantle, and not just a spinning core for spinning's sake.“This multidecadal periodicity coincides with changes in several other geophysical observations especially the length of day and magnetic field,” the authors write. “These observations provide evidence for dynamic interactions between the Earth's layers, from the deepest interior to the surface, potentially due to gravitational coupling, and the exchange of angular momentum from the core and mantle to the surface.”
