In this Journal Club episode, Rhonda Patrick, PhD and endurance athlete Brady Holmer dissect a new Nature Communications study of more than 70,000 adults showing that vigorous intensity is roughly 4–10x more potent than moderate activity for reducing all-cause mortality, cardiovascular events, type 2 diabetes, and cancer outcomes—far beyond the long-standing 1:2 rule embedded in global exercise guidelines.

Une découverte majeure publiée dans Nature Communications bouleverse notre manière de raconter l'histoire de l'humanité. Sur le site kényan de Nomorotukunan, les archéologues ont mis au jour un phénomène fascinant — et déroutant. Pendant près de 300 000 ans, des générations d'hominidés y ont façonné exactement les mêmes outils en pierre, sans la moindre innovation. Pas de progrès, pas de variation notable, pas d'amélioration technique. Une immobilité totale dans un monde pourtant en pleine mutation.Cette persistance dans la répétition interroge. On a longtemps imaginé la préhistoire comme une aventure continue d'inventions brillantes menant progressivement à l'Homo sapiens moderne. Mais Nomorotukunan raconte une autre histoire : celle d'une humanité qui, pendant une immense portion de son existence, a fait du conservatisme technologique la norme plutôt que l'exception.Les outils retrouvés ne sont pas n'importe quels objets : ce sont des artefacts appartenant à la tradition Oldowayenne, l'une des plus anciennes technologies humaines, apparue il y a environ 2,6 millions d'années. Ce sont des éclats simples, produits en frappant deux pierres l'une contre l'autre, utilisés pour couper, racler ou broyer. Leur fabrication, quasi immuable, suggère une maîtrise transmise, mais jamais réinventée. Cela implique des pratiques pédagogiques, une culture matérielle stable et, surtout, une absence totale de pression à innover.Comment expliquer cette stagnation ? D'abord, ces outils étaient probablement suffisants pour répondre aux besoins du quotidien. Quand une technologie fonctionne parfaitement pour chasser, découper ou dépecer, pourquoi en changer ? Ensuite, les hominidés de cette époque vivaient dans des environnements où la stabilité culturelle importait davantage que l'expérimentation individuelle. L'innovation, loin d'être une valeur universelle, est un concept moderne.Cette découverte nous oblige aussi à revoir notre définition du « progrès ». Ce que nous percevons aujourd'hui comme une évolution naturelle — l'amélioration continue des technologies — est en réalité une anomalie récente à l'échelle de notre histoire. Pendant des centaines de milliers d'années, le véritable pilier de la survie humaine n'était pas la créativité, mais la continuité.L'immobilité de Nomorotukunan n'est donc pas un signe d'infériorité intellectuelle. Au contraire, elle révèle que ces populations maîtrisaient déjà un savoir-faire optimisé, durable et parfaitement adapté à leur mode de vie. Le progrès n'était pas une priorité : la transmission fidèle d'un geste ancestral était la clé de la survie.En fin de compte, cette découverte bouleverse notre récit : l'humanité n'a pas toujours avancé grâce à l'innovation. Pendant la majorité de son histoire, elle a avancé grâce à la tradition. Hébergé par Acast. Visitez acast.com/privacy pour plus d'informations.

Un equipo internacional de científicos con participación del Instituto de Nanociencia y Materiales de Aragón INMA (CSIC/Unizar) ha logrado un avance sin precedentes (Nature Communications) en el campo de los materiales: crear un polímero capaz de organizarse por sí solo formando una estructura interna con cinco tipos distintos de cristales. Hasta ahora solo se había llegado al límite de cuatro. Alejandro J. Müller, profesor Ikerbasque en el Instituto Polymat de la UPV/EHU, y Víctor Sebastián, catedrático de Ingeniería Química e investigador del INMA, explican con detalle este avance y sus aplicaciones. Por otro lado, Ágora conversa con la vicerrectora Pilar Pina y los investigadores Rebecca Pagliari y Henrique Ferraz de Arruda sobre la renovación del sello de excelencia en Recursos Humanos en Investigación (HRS4R) obtenida por la Universidad de Zaragoza.

Send us a textA month of movement—across states, across continents, and across ideas—shapes this episode of Heart to Heart with Anna, where personal connection meets the frontiers of heart medicine. We begin with gratitude, travel, and family updates, then explore two breakthroughs shaping the future of congenital heart care: a major open-access study using whole-genome sequencing to forecast outcomes after CHD surgery, and nanotechnology that turns everyday implants into infection-resistant, tissue-regenerating tools.CHD News Article Referenced: “Genome sequencing is critical for forecasting outcomes following congenital cardiac surgery,” published in Nature Communications (open-access).

We often think of brain development as something that happens in childhood, stabilises in adulthood, and then gradually declines. However new research published in the journal Nature Communications suggests our brains actually move through five distinct eras, each with its own strengths, vulnerabilities, and turning points. Researchers analysed MRI brain scans from nearly 4,000 people aged between newborn and 90 years old. Their goal was to understand how the brain's internal wiring, changes over a lifetime. Dr. Michelle Dickinson joins Francesca Rudkin to break-down and analyse the study. LISTEN ABOVESee omnystudio.com/listener for privacy information.

Šogad Starptautiskais klimata samits (COP) radījis fundamentālus jautājumus par cilvēku spēju sadarboties - vai COP vēl ir kāda jēga? Vai šodien starpatutiskā klimata diplomātija vēl ir aktuāla, ja galveno emisiju ražotājvalstu vadītāji nav ieradušies uz ikgadējo klimata samitu? Vai diskusijas par atjaunīgajiem resursiem vairs ir aktuālas, ja lielvaru galvenais uzdevums ir ražot ekonomisku izaugsmi, neņemot vērā klimata pārmaiņas? Raidījumā Zināmais nezināmajā diskutē Pasaules dabas fonda Latvijā valdes priekšsēdētājs Jānis Rozīti, politologs un dezinformācijas pētnieks Mārtiņš Hiršs un Latvijas Universitātes pētnieks Jānis Brizga. "Līdztekus klimata pārmaiņu mazināšanai aizvien vairāk tiek runāts par pielāgošanos klimata pārmaiņām," norāda Jānis Rozītis. Viņš norāda, ka tas arī ir saistīts dezinformāciju, turklāt dažādiem dezinformācijas līmeņiem. "Šobrīd aizvien vairāk, bet tas varbūt arī ir virzīts no jaunattīstības valstīm, kuras šobrīd saskaras ar klimata ar pārmaiņām, visgraujošākā izpratnē. Sarunas sāk virzīties [par pielāgošanos], un tas ir bīstami. Pielāgoties bez pārmaiņu mazināšanas būs ārkārtīgi sarežģīti un noteikti vēl dārgāk. Līdz ar to jāstrādā abās frontēs. Bet šobrīd sarunas virzās uz to, ka arī trīsreiz jākāpina finanšu resursi, lai veicinātu pielāgošanos un noturību.  Ja Latvijā visu laiku uzskatījām, ka esam tādā paradīzes vietā, tad ir arī dažādi apskatnieki, kuri norāda, ka Eiropā Latvija arī kļūst par teritoriju, kuru diezgan būtiski klimata pārmaiņas jau ietekmē."   Zinātnieki atklājuši, ka derīgo izrakteņu ieguve okeāna gultnē izjauktu barbības ķēdes līdzsvaru okeāna krēslas zonā un potenciāli iznīcinātu okeāna gultnes organismus.  Jau vairākas desmitgades ir zināms par dziļjūras derīgajām ieguvēm, proti, dažādu minerālu un derīgo izrakteņu ieguvi no okeāna dzīlēm. Bet šobrīd saskaņā ar Havaju Universitātes Manoā jaunu pētījumu ir rasti pirmie tiešie pierādījumi tam, ka dziļjūras ieguves rezultātā radušies atkritumi varētu iznīcināt dzīvību okeāna krēslas zonā, konkrēti Klusā okeāna Klarjonas-Klipertona teritorijā. Tas ir viens no bagātākajiem dziļjūras reģioniem, jo tajā ir daudz mangāna konkrēciju, tas satur arī kobaltu, niķeli un varu, kas ir galvenās sastāvdaļas elektrotransportlīdzekļiem un atjaunojamās enerģijas tehnoloģijām. Zinātnieku komanda noteikusi, ka ieguves atkritumu izvadīšana ietekmētu 53% zooplanktona, 60% mikronektona, kas barojas ar zooplanktonu, un šādi traucējumi varētu skart barības ķēdi, galu galā ietekmējot arī lielākus plēsējus, piemēram, zivis, jūras putnus un jūras zīdītājus. Pētījuma rezultātus, kas novembra sākumā publicēti žurnālā “Nature Communications”, komentē Latvijas Hidroekoloģijas institūta vadošā pētniece, Latvijas Universitātes Medicīnas un dzīvības zinātņu fakultātes docente Ingrīda Andersone. Sākumā skaidrojam, kādas kopumā okeānā ir zonas un kas izceļ tieši krēslas zonu.

Ime tedna je postal Aleš Čadež, letošnji Inovativni mladi kmet, ki je na 11. Evropskem kongresu mladih kmetov v Bruslju prejel še naziv najboljšega mladega kmeta leta. Kot prvi Slovenec do zdaj je med 31 kandidati iz 27 držav izstopal s svojim delom in prepričal strokovno žirijo, poleg glavnega priznanja pa je prejel tudi nagrado za najboljši projekt energetske učinkovitosti. Kandidatki sta bili tudi: Tjaša Bertoncelj, strokovna vodja Nacionalne mreže TOM telefon, kjer usposobljeni svetovalci otrokom in mladostnikom v stiski na anonimni brezplačni številki že 35 let zagotavljajo varen in zaupen prostor. Prostovoljcem pod okriljem Zveze prijateljev mladine Slovenije lahko otroci vsak dan brez strahu pred stigmatizacijo zaupajo svoja čustva in težave. Maruša Bradač, astrofizičarka in vodja raziskovalne skupine na ljubljanski fakulteti za matematiko in fiziko, ekipe, ki je s teleskopom James Webb odkrila aktivno supermasivno črno luknjo v zgodnjem vesolju. Odkritje, ki so ga objavili v reviji Nature Communications, predstavlja ključen del sestavljanke o nastanku zgodnjih galaksij in črnih lukenj.

Oui, la musique peut réellement modifier nos souvenirs — pas seulement les raviver, mais aussi les transformer. C'est ce que montre une étude menée par des chercheurs de l'Institut de Technologie de Géorgie (Georgia Institute of Technology), publiée en 2023 dans la revue Nature Communications.Les neuroscientifiques y ont observé comment la musique influence la consolidation et la précision des souvenirs. L'expérience reposait sur un protocole simple : des volontaires devaient mémoriser des images pendant qu'ils écoutaient différentes séquences sonores — certaines musicales, d'autres neutres ou discordantes. Les chercheurs ont ensuite évalué, plusieurs heures plus tard, la fidélité des souvenirs associés à ces images.Résultat : la musique émotionnellement marquante modifiait la trace mnésique. Lorsqu'un morceau suscitait une émotion positive ou nostalgique, le souvenir devenait plus vivace, plus riche en détails. En revanche, une musique triste ou dissonante pouvait brouiller la mémoire d'origine, en y introduisant une coloration émotionnelle différente. Autrement dit, le souvenir se “réécrivait” partiellement, sous l'influence du ressenti musical.L'équipe dirigée par le Dr Caitlin Mullins a utilisé l'imagerie cérébrale (IRM fonctionnelle) pour comprendre le mécanisme. Elle a observé une coopération accrue entre l'amygdale, qui traite les émotions, et l'hippocampe, le centre de la mémoire épisodique. Cette synchronisation neuronale, induite par la musique, favorise à la fois la réactivation et la “mise à jour” du souvenir. Le cerveau, en quelque sorte, reconsolide la mémoire en y intégrant l'émotion du moment présent.Les chercheurs comparent ce phénomène à un processus d'édition : chaque fois que l'on se remémore un événement accompagné de musique, on le réimprime avec une nouvelle encre émotionnelle. Cela explique pourquoi une chanson peut nous replonger dans un souvenir heureux, mais aussi pourquoi, avec le temps, ce souvenir peut se teinter d'une nuance différente selon notre état émotionnel.En conclusion, selon l'étude du Georgia Institute of Technology, la musique ne se contente pas d'être une bande sonore de nos souvenirs : elle en est aussi un outil de réécriture. À chaque écoute, le cerveau réactive, colore et modifie subtilement le passé, prouvant qu'en matière de mémoire, rien n'est jamais complètement figé. Hébergé par Acast.

Ķīmija, lai arī bieži nemanāma un neuzkrītoša, ir klātesoša neskaitāmās mūsu dzīves jomās. Sākot ar produktiem mūsu vannasistabās un zāļu plauktos, beidzot ar enerģētiku un pārtikas drošību. Ķīmiķi Latvijā kopā ar fiziķiem šobrīd strādā pie nanopārklājumiem vēja turbīnu lāpstiņām un īpaša sensora, kas ziņotu par zivju produktu svaigumu. Par jaunākajiem pētījumiem raidījumā Zināmais nezināmajā stāsta Latvijas Universitātes (LU) asociētais profesors, Organiskās sintēzes institūta pētnieks, ķīmiķis Artis Kinēns un fiziķis no Ukrainas, LU Atomfizikas un spektroskopijas institūta vadošais pētnieks Romāns Viters. Stāstot par topošo zivju svaiguma kontroles sensoru, Artis Kinēns skaidro, ka pašreizējās tehnoloģijas, lai noteiktu pārtikas kvalitāti, bieži vien laboratorijas izmeklējumi. "Tas nozīmē, ka ir jāņem zivs paraudziņus, sūta uz laboratoriju, taisa mikrobioloģiskos testus. Tas aizņem labākajā gadījumā dažas stundas, realitātē - vairākas dienas. Tas nozīmē, ka tas svaigums, ko noteicāt, jau ir divas dienas vecs," norāda Artis Kinēns.  Otrs variants ir fizikālas metodes, kam nepieciešams fizisks kontakts ar zivi.  "Bet ko darīt, ja zivs ir iepakojumā? Ja atvērt iepakojumu vaļā, jau ir atkritums radies. Arī tad, ja zivs paraugu sūta uz laboratoriju, arī ir radīts atkritums. Līdz ar to nav labas tiešsaistes metodes, kurā būtu iespējams kontrolēt pārtikas produktu, kas jau ir iepakojumā, lai tas nebūtu jāatver." "Galvenā priekšrocība, ko redzam pret klasisko derīguma termiņu, jo arguments būtu, derīguma termiņš ir uzdrukāts, viss kārtībā. Bet derīguma termiņš nekādā veidā nepastāsta, kā tā zivs ir bijusi glabāta. Ja viņi ir pa ceļam vesta ar ķerrā, bez saldēšanas, tad viņa būs sabojāsies krietni ātrāk, nekā ir derīguma termiņš uzrakstīts. No otras puses, ja viņa ir glabāta korekti, tas derīguma termiņš arī varbūt nav korekts. Viņš vienkārši pasaka, ka šeit būs droši, ja mēs viņu metīsim ārā. Bet tikpat labi viņa ir lietojama vēl varbūt nedēļu," analizē Artis Kinēns. "Pateicoties tam, ka nav tāda ātra kontroles mehānisma, es teikšu diezgan šausmīgu statistiku, ka aptuveni 30% no saražotās zivju produkcijas tiek izmesta ārā tikai tāpēc, ka nenonāk līdz galapatērētājam laikā." Daļa šīs produkcijas noteikti vēl būtu lietojama, bet termiņš saka, ka ir jāmet ārā. "Inovācija būtu tāda, ka, ja mēs varam šo ieviest kā standarta praksi, ka mums ir iepakojums, kurā iekšpusē ir uzlīme, kurā ir iestrādāts luminofors, tad to no ārpuses var noskenēt vai nu ar kādu lasītājierīci, ideālā gadījumā mobilo telefonu, un tas pasaka: zivs vēl ir derīga tik un tik ilgu laiku," skaidro Artis Kinēns. Pētnieks norāda, ka šobrīd mērķis ir topošo sensoru un iespējas ar to veikt svaiguma mērījumus piedāvāt pārtikas izplatītājiem un pārtikas veikaliem, lai viņiem būtu iespēja labāk kontrolēt savu produktu plūsmu, lai tā samazinātu atkritumu rašanos.  "Viņu gadījumā tā ir mobilā telefona aplikācija, visticamāk, kura nofotografē uzlīmīti, kas ir  iekšpusē pie zivs pielikta, un no tās fotogrāfijas viņš nolasa zivs svaigumu," atzīst Artis Kinēns. "Ja runājam par patērētājiem, tad pielietojums varētu būt ļoti līdzīgs - ar mobilo  telefonu nofotografē zivi veikalā un lietotne pasaka, ka zivs ir derīga vai nav." Zinātnes ziņas Ziemā vērts vakariņas ēst agrāk Laikā, kad ārā agri paliek tumšs, izrādās, ka ir vērts pārskatīt mūsu vakariņu paradumus un ieturēt maltīti agrāk! Pētnieki no Džona Hopkinsa universitātes analizējuši sasitību starp mūsu iekšējo pulksteni un vielmaiņu un secinājuši, ka ēdot vakariņas ziemā agrāk, mēs palīdzam savam organismam labāk pārstrādāt uzņemto pārtiku. Arī dzīvnieki var sirgt ar hiperaktivitātes sindromu Cilvēku pasaulē ir tik ierasti runāt par tādām diagnozēm kā autisms, arī uzmanības deficīta un  un izskatās,  ka arī daži mūsu mājdzīvnieki varētu sirgt ar līdzīgām kaitēm. Tas tāpēc, ka pie vainas abos gadījumos ir strukturālas un ķīmiskas izmaiņas smadzenēs. Pētnieki noskaidorjuši, ka, piemēram, suņiem, žurkām, pelēm un atsevišķiem primātiem var būt izmaiņas gēnos, kas saistītas ar hiperaktīvu un impulsīvu uzvedību. Regulāra mikroplastmasas lietošana paātrina aterosklerozes veidošanos Kalifornijas universitātes pētnieki papildinājuši mūsu zināšanas par mikroplastmasas ietekmi uz cilvēka organismu. Eksperimentos ar pelēm, atklāts, ka regulāra mikroplastmasas lietošana paātrina aterosklerozes veidošanos. Ateroskleroze ir stāvoklis, kad sašaurinās artērijas, radot lielāku insulta vai infarkta risku. Te gan jāpiebilst, ka pētījumā šādus rezultatus uzrādīja tieši peļu tēviņi nevis mātītes. Abu dzimumu peles baroja ar zemam holesterīnam labvēlīgu diētu, taču regulāri deviņu mēnešu laikā pelēm tika iebarota arī mikroplastmasa atbilstoši dzīvnieku svaram.  E.coli baktērijas izplatība ir tikpat ātra kā cūku mērim Tīmekļa vietnē “ScienceDaily” ar pirmpublikāciju zinātnes žurnālā “Nature Communications” nonācis raksts par kādu zarnu baktērijas jeb Escherichia coli īpašību. Zinātnieki no Somijas un Norvēģijas pirmo reizi ir novērtējuši, cik ātri E.coli baktērijas var izplatīties starp cilvēkiem, un, kā izrādās, viens šīs baktērijas celms izplatās tikpat ātri kā cūku gripa. Pētnieku darbs piedāvā jaunu veidu, kā uzraudzīt un kontrolēt pret antibiotikām izturīgas jeb rezistentas baktērijas. Antimikrobiālā jeb antibiotiku rezistence ir aktuāla problēma veselības aprūpē, un tieši šonedēļ līdz 24. novembrim aizrit Pasaules antimikrobiālās rezistences izpratnes nedēļa. Tāpēc par baktērijas izplatību, bīstamību un, protams, ārvalstu pētnieku paveikto saruna ar Eiropas Pārtikas nekaitīguma iestādes valdes priekšsēdētāju, kā arī Pārtikas drošības, dzīvnieku veselības un vides zinātniskā institūta “BIOR” zinātniskās padomes priekšsēdētāju Aivaru Bērziņu.

In this podcast episode, MRS Bulletin's Laura Leay interviews Mischa Bonn, director of the Max Planck Institute for Polymer Research in Germany and Dr. Yongkang Wang, group leader affiliated with the Max Planck Institute for Polymer Research as well as Southeast University in Nanjing, China about their research on nanoconfined water. The researchers determined that interfacial rather than nanoconfinement effects govern water structure at the eight Ångstrom level. At five Ångstroms, nanoconfinement effects start to appear with the water molecules starting to lie flat, parallel to the interfaces, and the hydrogen bonding network beginning to weaken. The results may lead to a better understanding of nanofluidic devices, and have implications for desalination, water purification, and hydrogen generation.This work was published in a recent issue of Nature Communications. 

Le scénario est souvent celui-ci : Il pleure. Sa voix tremble. On devine les sanglots étouffés d'un jeune homme en détresse. Il dit s'appeler Lucas, il dit avoir eu un accident. Il a besoin d'aide. Et vous, à l'autre bout du fil, vous n'avez aucun doute : c'est bien la voix de votre neveu. Vous la reconnaissez. Sauf que… Lucas n'a jamais décroché son téléphone. Ce n'est pas lui. C'est une IA.Autre scénario, et qui a vraiment eu lieu celui-ci, en 2023, Jennifer DeStefano, une mère de famille américaine, reçoit un appel paniqué : sa fille de 15 ans, Briana, pleure, supplie qu'on vienne la sauver. En arrière-plan, des voix masculines hurlent qu'ils vont lui faire du mal si elle ne paie pas une rançon. Jennifer est tétanisée : la voix est celle de sa fille, les intonations, les sanglots, tout y est. Mais la police découvrira plus tard qu'il s'agissait d'une copie vocale générée par IA à partir de quelques secondes de vidéos postées sur TikTok. L'arnaque n'a duré que quelques minutes, mais elle a suffi à plonger une famille entière dans la terreur. Depuis, les experts en cybersécurité tirent la sonnette d'alarme : les IA vocales émotionnelles savent désormais imiter non seulement la voix, mais aussi la peur, la douleur, la tendresse. Bref les émotions ! En moins d'une minute d'enregistrement, un logiciel peut ainsi créer une fausse conversation chargée émotionnellement et d'une authenticité glaçante.C'est ce qu'on appelle des “arnaques émotionnelles IA” et elles se multiplient : faux appels d'urgence, fausses vidéos de proches, voire faux amoureux numériques sur des sites de rencontre, capables de vous parler des heures avant de réclamer une aide financière.Le danger, vous l'avez compris, et c'est là toute la nouveauté, c'est l'émotion. Ces IA savent exactement où frapper : dans le réflexe humain de compassion. Pourquoi ? Parce que ace à une voix qui pleure, notre cerveau perd en rationalité. Il baisse la garde. Une étude neuro-cognitives publiée en 2024 dans Nature Communications montre ainsi que lorsqu'une voix émotive (pleurs, détresse) parvient à un auditeur, la réponse cérébrale de celui-ci priorise le signal affectif plutot que la rationnalité— ce qui réduit la vigilance et favorise une décision impulsive.La solution ?

Pourquoi les femmes sont-elles plus souvent touchées par la dépression ? Depuis des décennies, les chercheurs observent une réalité constante : les femmes présentent deux fois plus de risques que les hommes de souffrir d'un épisode dépressif au cours de leur vie. Longtemps, on a attribué cette disparité à des facteurs sociaux, hormonaux ou psychologiques. Mais une vaste étude internationale vient bouleverser notre compréhension du phénomène : la différence serait aussi génétique.Publiée en octobre dans la revue Nature Communications, cette recherche a été menée par le QIMR Berghofer Medical Research Institute en Australie. Elle a mobilisé les données génétiques de plus de 1,3 million de personnes, issues de plusieurs cohortes internationales, ce qui en fait l'une des plus grandes études jamais réalisées sur la dépression. Les scientifiques ont analysé les variations du génome pour identifier les régions associées au risque de développer la maladie.Résultat : les femmes porteraient un fardeau génétique plus lourd que les hommes face à la dépression. Concrètement, cela signifie que les gènes impliqués dans les troubles de l'humeur exercent chez elles une influence plus forte. Les chercheurs ont notamment découvert plus de 90 zones génétiques liées à la dépression, dont plusieurs présentent des effets marqués dans le génome féminin.Cette différence pourrait s'expliquer par des interactions complexes entre gènes et hormones. Les œstrogènes, par exemple, modulent la production de neurotransmetteurs tels que la sérotonine et la dopamine, qui jouent un rôle central dans la régulation de l'humeur. Lorsque l'équilibre hormonal est perturbé — comme après un accouchement, à la ménopause ou pendant le cycle menstruel —, les femmes génétiquement prédisposées deviennent plus vulnérables à un épisode dépressif.Les chercheurs du QIMR insistent cependant sur un point : cette vulnérabilité n'est pas une fatalité. Si la génétique explique une part du risque, l'environnement, le stress, les traumatismes et les facteurs sociaux restent déterminants. Mais cette découverte ouvre la voie à une médecine plus personnalisée : en identifiant les signatures génétiques spécifiques aux femmes, il sera peut-être possible de développer à terme des traitements mieux ciblés, adaptés à leur profil biologique.En somme, cette étude confirme que la dépression n'est pas une faiblesse mais une maladie à composante biologique complexe — et qu'en matière de génétique, les femmes portent effectivement un poids un peu plus lourd à combattre.

Le 27 octobre 2025, une étude publiée dans la revue Nature Communications a remis en question l'utilité réelle des télévisions ultra haute définition. Des chercheurs de l'Université de Cambridge et du laboratoire Meta Reality Labs ont voulu répondre à une question simple : notre œil humain perçoit-il vraiment la différence entre une image en 4K, 8K ou une résolution plus basse ? Leur conclusion est sans appel : au-delà d'un certain point, notre vision ne peut tout simplement plus distinguer les détails supplémentaires.Les écrans ultra HD se vantent d'afficher des millions de pixels supplémentaires – 8 millions pour la 4K, plus de 33 millions pour la 8K. En théorie, plus il y a de pixels, plus l'image semble nette. Mais en pratique, notre œil a une limite de résolution, mesurée en « pixels par degré de vision » (PPD). Cela représente combien de détails l'œil peut discerner dans un angle d'un degré. Dans leurs expériences, les chercheurs ont exposé des volontaires à des images aux contrastes et couleurs variables, et ont mesuré le point où la netteté cessait d'être perçue comme améliorée. Résultat : le seuil moyen était d'environ 90 PPD. Au-delà, les différences deviennent imperceptibles, même si l'écran affiche beaucoup plus d'informations.Prenons un exemple concret. Dans un salon typique, si vous êtes assis à 2,5 mètres d'un téléviseur de 110 centimètres de diagonale (environ 44 pouces), vous ne ferez pas la différence entre une image en 4K et en 8K. L'œil humain ne peut pas discerner autant de détails à cette distance. Pour vraiment profiter de la 8K, il faudrait soit un écran gigantesque, soit s'asseoir à moins d'un mètre – ce qui est peu réaliste pour regarder un film confortablement.Ces résultats soulignent une réalité simple : les gains de résolution vendus par les fabricants dépassent désormais les capacités biologiques de notre vision. Autrement dit, nous avons atteint un plafond perceptif. Acheter une TV 8K pour remplacer une 4K revient un peu à utiliser une loupe pour lire un panneau routier à un mètre de distance : la différence existe techniquement, mais votre œil ne la voit pas.Les chercheurs estiment qu'il serait plus utile d'améliorer d'autres aspects de l'image, comme la luminosité, le contraste, la fidélité des couleurs ou la fluidité des mouvements. Ces paramètres influencent beaucoup plus notre perception de la qualité qu'une hausse du nombre de pixels. En clair, la course à la résolution touche à sa fin : la vraie révolution de l'image ne viendra plus du nombre de points, mais de la manière dont ils sont rendus. Hébergé par Acast.

Más píxeles de los que ves: Pantallas 8K y 4K prometen imágenes más nítidas, pero un estudio demuestra que tus ojos no las distinguen.  Por Félix Riaño @LocutorCo  Investigadores de Cambridge y Meta descubrieron que el ojo humano tiene un límite real para detectar detalles en pantallas. Más allá de cierto punto, los televisores Ultra HD no se ven mejor, aunque cuesten miles de dólares.  Sigue el pódcast Flash Diario para descubrir más curiosidades de ciencia y tecnología.  Científicos de la Universidad de Cambridge y del laboratorio de realidad de Meta analizaron cuántos píxeles puede distinguir el ojo humano en distintas condiciones. Su conclusión es clara: en un salón promedio, una pantalla 4K o 8K no ofrece una diferencia visible frente a una 2K. El estudio, publicado en Nature Communications, demuestra que los límites de nuestra visión convierten muchos televisores de alta gama en un gasto innecesario. A partir de ahora, la ciencia tiene una medida precisa para responder una pregunta que millones de personas se han hecho frente a una vitrina: ¿realmente se ve mejor un televisor más caro?  Más píxeles no siempre significan mejor imagen, solo más gasto.  Durante años, las marcas de televisión han competido por ofrecer resoluciones más altas: primero Full HD, luego 4K, después 8K. Cada salto prometía una experiencia visual “más real”. Pero un equipo de Cambridge y Meta quiso poner esa promesa a prueba. Construyeron un experimento con un monitor 4K de 27 pulgadas montado en un riel móvil. Dieciocho personas con visión normal observaron líneas finas en distintos colores y distancias. Cuando las líneas eran demasiado pequeñas, los voluntarios ya no podían distinguirlas: veían solo una mancha gris. Con esa información, los científicos calcularon la capacidad real del ojo humano para detectar píxeles individuales.  El resultado fue sorprendente. La mayoría de las personas puede distinguir hasta 94 píxeles por grado en escala de grises, y unos 89 cuando se trata de colores rojo y verde. En cambio, los tonos amarillo y violeta caen hasta 53 píxeles por grado, porque nuestro cerebro procesa peor los detalles de color que los de luz y sombra. Esa limitación biológica significa que, si tienes una televisión de 44 pulgadas y la ves a unos 2,5 metros de distancia —como en la mayoría de salas—, ya estás recibiendo más detalle del que tu vista puede procesar. En otras palabras: comprar una tele 8K no hace que veas mejor, solo hace que pagues más.  Los científicos publicaron una tabla y una calculadora en línea que permiten saber si un televisor realmente ofrece mejoras visibles según el tamaño y la distancia de visualización.Aquí tienes el enlace a la calculadora en línea de la University of Cambridge:Display resolution calculatorPor ejemplo, una pantalla de 40 pulgadas vista a 3 metros se aprovecha totalmente en resolución Full HD. Para notar la diferencia con 4K, habría que acercarse mucho o tener un televisor gigante. Incluso para que una pantalla 8K valga la pena, necesitarías una de 100 pulgadas y verla desde menos de 2 metros. Además, cada píxel adicional consume más energía, requiere más potencia de procesamiento y eleva el precio sin ofrecer beneficios visuales.  El estudio también tiene implicaciones fuera del salón de casa. En la realidad virtual, los videojuegos y los móviles, muchas empresas invierten en pantallas con densidades imposibles de distinguir. Cambridge y Meta advierten que ese esfuerzo podría redirigirse a mejoras más perceptibles, como el contraste, el color o la velocidad de respuesta. El hallazgo pone en duda prácticas comunes como la “submuestra de color”, usada para ahorrar ancho de banda al reducir la resolución de los tonos. El estudio demuestra que el ojo distingue más matices rojo-verde de lo que se creía, lo que podría transformar la forma de comprimir video en el futuro. En resumen, no es que las pantallas 8K sean malas, es que nuestros ojos ya llegaron a su límite.  La ciencia confirma que el ojo humano tiene un límite de detalle. Si ves tu tele desde el sofá, 4K ya es más de lo que puedes distinguir. Antes de gastar en 8K, consulta la calculadora de Cambridge y revisa si realmente lo necesitas.Científicos de Cambridge descubren que el ojo humano no nota diferencia entre 2K, 4K y 8K en tu sala de casa.

What if your body is learning things your mind doesn't know? What if memory wasn't just something that our brain has?Episode Summary On this episode, I'm exploring a bold idea with neuroscientist Dr Nikolay Kukushkin: memory doesn't just live in the brain. It might be a basic property of life itself. We unpack how scientists define memory (behavioural change over time) versus how the rest of us use the word, and why that distinction matters—from sea slugs to kidney cells. I ask the “muscle memory” question we all carry, and we separate the metaphor from the biology: your basal ganglia automate behaviours, but your muscle cells do literally adapt to patterned use.We go deep on “patterns.” Nikolay's work shows that even non-neural cells can detect minute-scale timing differences—preferring spaced pulses over a single crammed dose. That has huge implications for learning, exercise, nutrition, and even medicine; it suggests timing might be as important as quantity. We also talk about sleep as essential “synaptic housekeeping,” why false memories are an adaptive feature (not a failure), and what it really means to “run out of memory” in our overstimulated world.Finally, we tilt at the big questions: how consciousness might have evolved, why Plato's model of perception eerily echoes today's top-down/bottom-up neuroscience, and what AI still lacks—learning patterns in time within an embodied world. If you've ever crammed for an exam, worried about forgetting your own name, or wondered what your cells are quietly learning from your daily routines, this one will rewire how you think about memory.Guest Biography — Dr Nikolay KukushkinDr Nikolay Kukushkin is a Clinical Associate Professor at NYU. His book One Hand Clapping: Unraveling the Mystery of the Human Mind  traces how consciousness emerged from the natural world; the original Russian edition won the Enlightener (Prosvetitel) Award and the Alexander Belyaev Medal.His recent research (Nature Communications, Nov 2024) showed that non-neural human cells display the classic “spacing effect,” suggesting memory-like temporal patterning beyond the brain.AI-Generated Timestamped Summary [00:00:00] Cold open: reframing memory as cellular, not just neural.

In this episode of SpaceTime, we uncover the latest findings in Martian meteorology, delve into Earth's ancient tectonic activity, and prepare for humanity's return to the Moon.Raging Winds on Mars: Unveiling Martian Weather PatternsA groundbreaking study published in the journal Science Advances reveals that wind speeds on Mars can reach up to 160 km/h, significantly higher than earlier estimates. Lead author Valentin U.H. Meckel from the University of Bern discusses how these powerful winds, along with dust devils, play a crucial role in shaping Mars' climate and dust distribution. This episode explores how the observations from the European Space Agency's Mars Express and ExoMars Trace Gas Orbiter have provided unprecedented insights into Martian atmospheric dynamics, which are essential for planning future manned missions to the Red Planet.Unlocking Earth's Deep Past: New Insights into SubductionIn a surprising twist to our understanding of early Earth, a new study published in Nature Communications suggests that subduction and continental crust formation occurred much earlier than previously believed. Researchers utilized advanced geochemical analysis of ancient olivine crystals to challenge the notion of a stagnant lid tectonic regime during the Hadean eon. This episode discusses the implications of these findings on our understanding of Earth's geological history and the processes that shaped our planet's surface.NASA's Artemis II: Preparing for Lunar ExplorationNASA is set to send astronauts back to the Moon with the Artemis II mission, slated for launch in early 2026. This episode provides an overview of the mission's objectives, including a ten-day crewed flyby of the Moon, which will test the Orion spacecraft and gather crucial scientific data. As the crew prepares to explore the lunar far side, we discuss the significance of this mission for future lunar habitation and potential manned missions to Mars.www.spacetimewithstuartgary.com✍️ Episode ReferencesScience Advanceshttps://www.science.org/journal/sciadvNature Communicationshttps://www.nature.com/ncomms/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.Raging Winds on Mars: Unveiling Martian Weather PatternsUnlocking Earth's Deep Past: New Insights into SubductionNASA's Artemis II: Preparing for Lunar Exploration(00:00) Wind speeds on Mars and their implications(12:45) New findings on early Earth's tectonic activity(21:15) NASA's Artemis II mission overview(30:00) Science report: Octopus handedness and air pollution effects on sleep apnea

Nella puntata 582 esploriamo tre modi diversi di indagare la mente e la realtà: dalla creatività che mantiene giovane il cervello, al sonno che regola emozioni e memoria, fino alle misurazioni quantistiche che sfidano i limiti stessi della conoscenza.Ilaria ci racconta come un recente studio pubblicato su Nature Communications ha dimostrato che diverse attività creative come suonare, ballare o dipingere possano mantenere il cervello giovane. I ricercatori hanno utilizzato particolari “orologi cerebrali” per stimare l'età biologica del cervello e hanno osservato che, in alcune persone creative, esso risulta fino a sette anni più giovane rispetto all'età anagrafica.Le analisi hanno evidenziato come chi si dedica regolarmente a esperienze artistiche o cognitive — dal tango ai videogiochi strategici — presenti una rete di connessioni neuronali più efficiente. Vi state tutti già iscrivendo ad un corso di tango? Per approfondire: https://neurosynth.org/Nell'esterna di questa settimana Anna intervista il Dr. Mattia Aime, Professore e neuroscienziato all' Università di Berna in Svizzera. Mattia studia uno dei fenomeni cognitivi più affascinanti: il sonno. E la sua ricerca sta portando alla luce quanto il sonno sia importante non solo per le nostre capacità cognitive ma anche per le capacità di regolare le nostre emozioni. Ne vogliamo parlare perché' nella nostra società il sonno spesso viene visto come qualcosa di superfluo che ci fa perdere tempo riducendo la nostra performance. Tanto che abbiamo addirittura dei proverbi a riguardo e nell'intervista cominciamo proprio da uno di questi: sarà vero che ci dorme non piglia pesci?Andrea infine ci ricorda che ogni progresso scientifico si basa su misure sempre più precise, e che la meccanica quantistica, pur offrendo strumenti straordinari per migliorare la precisione, impone anche dei limiti, per esempio il principio di indeterminazione di Heisenberg, secondo cui non si possono conoscere contemporaneamente con accuratezza assoluta grandezze come posizione e quantità di moto.Un recente studio ha però mostrato come sia possibile aggirare questo vincolo misurando invece osservabili modulari, grandezze “compatibili” che rappresentano una sorta di versione quantistica complementare di quelle normalmente incompatibili.I ricercatori hanno realizzato questo tipo di misura utilizzando gli stati a griglia del moto meccanico di uno ione intrappolato, ottenendo incertezze inferiori al limite quantico standard. Hanno inoltre esteso l'approccio a un'altra coppia di osservabili, numero e fase, dimostrando un vantaggio metrologico rispetto ai limiti classici.Diventa un supporter di questo podcast: https://www.spreaker.com/podcast/scientificast-la-scienza-come-non-l-hai-mai-sentita--1762253/support.

In this podcast episode, MRS Bulletin's Sophia Chen interviews Bharat Gwalani from North Carolina State University and Mert Efe from Pacific Northwest National Laboratory about their single-step, energy-efficient method for making a samarium cobalt magnet. Using a process they call “friction stir consolidation,” the researchers apply heat and pressure simultaneously to fuse the two powders together. Their method results in low porosity to make a magnetically stronger, higher quality material than that made by using the conventional method. This work was published in a recent issue of Nature Communications.

Today's Headlines: The government is officially shut down, and OMB apparently spent its last working hours ordering at least 16 federal agencies to send out a pre-written email blaming Democrats for it—an illegal little parting gift to federal workers. With the shutdown, you can forget about getting jobs or inflation data for now (except from payroll firm ADP, which says companies shed 32,000 jobs in September—so, yeah, not great). Meanwhile, the Supreme Court told Trump he can't just boot Fed Governor Lisa Cook on the spot, kicking that fight to January. At the Pentagon, Pete Hegseth is rolling out strict NDAs and even random polygraphs for thousands of staffers, including top brass, in his ongoing war against leakers. And in actual science news, researchers in Nature Communications announced they've managed to create functional human eggs from skin cells in a lab—early proof-of-concept that could eventually transform fertility treatments, though no babies are being made from them anytime soon.

Before the written word — and possibly even before speech — humans have communicated through drawing. From crude scratches in the dirt or on cave walls to the arcane symbology of the laboratory whiteboard, our instinct for conveying our thoughts visually is pretty extraordinary. We see or understand something in the world, we build an idea in our mind of what we think we see, and then using our hand and the utensil we re-create it to communicate the share our perception with others. Along the way, we add in our own understanding and experience to craft that communication in ways that might not correspond with a specific object in the world at all.How we do this — and how we can learn to be better visual communicators — is at the heart of our conversation with Judy Fan, who runs the Cognitive Tools Lab in Stanford University's Department of Psychology.We've been nominated for a 2025 Signal Award for Best Science & Education Podcast!

Dust from car tires can be bad for fish — what might it do to us?As car tires wear, they shed billions of ultrafine particles of rubber that contain a complex mix of chemicals, including one called 6PPD-Quinone that's been linked to mass die-offs of migrating salmon. Now researchers are sounding the alarm that this chemical is accumulating in humans, and we have no clear understanding of its toxicity. An international team of scientists, including Rachel Scholes from the University of British Columbia, are calling for more scrutiny of the chemicals that go into car tires, since so much ends up in our environment. Their paper was published in the journal Environmental Science & Technology Letters.Fecal Transplants seem to have lasting metabolic effectsTransplanting the gut microbiome has been held out as a hope for a range of disorders, from obesity to mental health issues. A study that followed obese adolescents four years after receiving a fecal microbiota transplant from healthy individuals has shown positive impacts on the recipients' weight and metabolic health. Dr. Wayne Cutfield, a pediatrician and professor of pediatric endocrinology at the University of Auckland in New Zealand, said they also found after all this time that the donor bacteria have remained established in the recipients' gut microbiome. The study is in the journal Nature Communications. An ant queen clones sexual slaves of another species for her daughtersIn a truly bizarre tale from the animal world, researchers have discovered a species of ant where the queen gives birth to males of two totally different species. Somewhere along their evolutionary path, these Messor ibericus queen ants in southern Europe developed an ability to clone male Messor structor ants for her daughters to mate with and to produce a hybrid working class. Jonathan Romiguier, an evolutionary biologist from the University of Montpellier in France, said these M. ibericus ants essentially domesticated ants of another species. The study was published in the journal Nature. Why other apes can't walk a mile in our shoesA feature that distinguishes humans from other primates is the ability to walk upright. The major evolutionary change in the structure of our pelvis that allows for our bipedalism has now been traced genetically and developmentally. Human pelvic blades initially form in the embryo like other primates, but then flip their growth from vertical to horizontal, to give the human pelvis its unique basin shape. This new research led by Terence Capellini, Chair of the human evolutionary biology department at Harvard University and postdoctoral student Gayani Senevirathne, was published in the journal Nature.Women glow. So do men. Understanding our 'inner light'You might have been told by an admirer that you have a unique glow. In two groundbreaking studies, researchers have demonstrated the reality of that poetic compliment. Using ultra-sensitive instruments capable of detecting individual photons, Canadian researchers have imaged a biological source of incredibly faint light, known as Ultraweak Photon Emissions (UPE), that has potential as a future non-invasive diagnostic imaging tool. Daniel Oblak, an associate professor of physics and astronomy at the University of Calgary, oversaw a study where they unequivocally demonstrated that living things, like mice, give off an extremely faint glow that dims when they die. His study was published in The Journal of Physical Chemistry Letters. In a separate study, Nirosha Murugan, — an assistant professor of tissue biophysics at Wilfred Laurier University — discovered that these UPEs can also detect different mental states in the brain. That study was published in the journal iScience.

Dr. Eli Levenson-Falk joins Sebastian Hassinger, host of The New Quantum Era to discuss his group's recent advances in quantum measurement and control, focusing on a new protocol that enables measurements more sensitive than the Ramsey limit. Published in Nature Communications in April 2025, this work demonstrates a coherence stabilized technique that not only enhances sensitivity for quantum sensing but also promises improvements in calibration speed and robustness for superconducting quantum devices and other platforms. The conversation travels from Eli's origins in physics, through the conceptual challenges of decoherence, to experimental storytelling, and highlights the collaborative foundation underpinning this breakthrough.Guest BioEli Levenson-Falk is an Associate Professor at USC. He earned his PhD at UC Berkeley with Professor Irfan Siddiqui, and now leads an experimental physics research group working with superconducting devices for quantum information science. Key TopicsThe new protocol described in the paper: “Beating the Ramsey Limit on Sensing with Deterministic Qubit Control." Beyond the Ramsey measurement: How the team's technique stabilizes part of the quantum state for enhanced sensitivity—especially for energy level splittings—using continuous, slowly varying microwave control, applicable beyond just superconducting platforms. From playground swings to qubits: Eli explains how the physics of a playground swing inspired his passion for the field and lead to his understanding of the transmon qubit, and why analogies matter for intuition. Quantum decoherence and stabilization: How the method controls the “vector” of a quantum state on the Bloch sphere, dumping decoherence into directions that can be tracked or stabilized, markedly increasing measurement fidelity. Calibration and practical speedup: The protocol achieves greater measurement accuracy in less time or greater accuracy for a given time investment. This has implications for both calibration routines in quantum computers and for direct quantum measurements of fields (e.g., magnetic) or material properties. Applicability: While demonstrated on superconducting transmons, the protocol's generality means it may bring improved sensitivity to a variety of platforms—though the greatest benefits will be seen where relaxation processes dominate decoherence over dephasing. Collaboration and credit: The protocol was the product of a collaborative effort with theorist Daniel Lidar and his group, also at USC. In Eli's group, Malida Hecht conducted the experiment.Why It MattersBy breaking through the Ramsey sensitivity limit, this work provides a new tool for both quantum device calibration and quantum sensing. It allows for more accurate and faster frequency calibration within quantum processors, as well as finer detection of small environmental changes—a dual-use development crucial for both scalable quantum computing and sensitive quantum detection technologies.Episode Highlights Explanation of the “Ramsey limit” in quantum measurement and why surpassing it is significant. Visualization of quantum states using the Bloch sphere, and the importance of stabilizing the equatorial (phase) components for sensitivity. Experimental journey from “plumber” lab work to analytic insights, showing the back-and-forth of theory confronting experiment. Immediate and future impacts, from more efficient calibration in quantum computers to potentially new standards for quantum sensing. Discussion of related and ongoing work, such as improvements to deterministic benchmarking for gate calibration, and the broader applicability to various quantum platforms.If you enjoy The New Quantum Era, subscribe and tell your quantum-curious friends!

In this episode of the Epigenetics Podcast, we talked with Emily Wong from the University of New South Wales in Sydney about her work on how evolution shapes mammalian genes. As the head of the Regulatory Systems Lab at the Victor Chang Cardiac Research Institute and an associate professor at UNSW, Emily's research centers on gene control and enhancers. We delve into her pivotal 2017 publication in Nature Communications, where she investigated transcription factor binding in liver-specific contexts, shedding light on the regulatory mechanisms at play in mammals. Emily elaborates on her postdoctoral work at the European Bioinformatics Institute and the innovative hybrid systems she used to dissect genetic variation effects, which allowed her to differentiate between cis-regulatory and trans-regulatory influences. By employing techniques like ChIP-seq, she was able to illustrate the combinatorial effects of transcription factors on gene expression, paving the way for her collaborative efforts across disciplines and organisms. We also examine Emily's findings regarding enhancer function through comparative studies between zebrafish and marine sponges. Using historical data on conserved genetic sequences, she and her team identified enhancer regions that displayed activity in specific vertebrate cell types, despite their evolutionary divergence from sponges. This unexpected result suggests deeper insights into how enhancers can be co-opted for new functions as species evolve. Furthermore, we dive into Emily's latest ventures involving advanced methodologies such as chromatin accessibility profiling with ATAC-seq and how these insights can elucidate the genomic landscape of metazoan embryogenesis. She highlights significant correlations between enhancer turnover and DNA replication timing, suggesting evolutionary implications that should be taken into account in future genomic studies.   References Wong, E.

Sarcopenia, the age-related loss of muscle mass and strength, begins subtly in midlife and accelerates with age, increasing your risk of frailty, falls, and fractures As your body ages, muscles become less responsive to training, and physical gains come more slowly, even when effort and consistency remain the same A 2025 study published in Nature Communications found that older muscles fail to activate key growth pathways and repair signals after exercise, explaining the reduced adaptation Despite slower gains, exercise remains essential not just for physical strength but also for brain function, heart health, immune regulation, and metabolic resilience across the aging process Longevity benefits peak at around 40 to 60 minutes of strength training per week; exceeding this reverses the gains and increases the risk of overtraining

What if medicine worked to get you healthier overall—not just people like you or for one or another symptom? In the latest episode of TGen Talks, host Karie Dozer sits down with Nicholas Schork, Ph.D., and Laura Goetz, M.D., co-authors of a recent commentary published in Nature Communications, From Precision Interventions to Precision Health, to explore the promise—and complexity—of truly personalized healthcare. Traditional medicine treats symptoms. Precision healthcare, however, rethinks that model entirely. By tapping into genomics, environment, lifestyle, and even real-time data from wearable devices, Drs. Schork and Goetz discuss developing highly individualized approaches that don't just treat illness—they aim to prevent it. Together, they unpack how this shift could redefine everything from how drugs are tested, to how diseases are managed, and even how we define “health.” They discuss cutting-edge innovations like anti-sense oligonucleotides—drugs custom-made for an individual's genetic code—and the rise of geroprotectors, compounds designed to support whole-body wellness as we age. They discuss the difficulties of such specific treatments and the differences in the way different patients might metabolize and respond to the same medicine. The future of medicine isn't one-size-fits-all. It's N-of-1—and it might just be closer than you think.

In this episode of SpaceTime, we uncover groundbreaking discoveries and innovative advancements in the realm of space and planetary science.Record-Breaking Cosmic Structure DiscoveredAstronomers have imaged an unprecedented cosmic structure, a massive cloud of energetic particles surrounding a galaxy cluster that spans nearly 200 million light years. This remarkable finding, presented at the 246th meeting of the American Astronomical Society, challenges existing theories about particle energization, suggesting that giant shock waves and turbulence are at play rather than nearby galaxies. We delve into the implications of this discovery for our understanding of cosmic magnetic fields and the dynamics of galaxy clusters.A New Approach to Building MarsA recent study has revealed a novel method for planetary core formation, suggesting that molten sulfide rather than metal could create a core in rocky planets like Mars. This research, published in Nature Communications, offers fresh insights into the early evolution of terrestrial worlds, particularly in sulfur-rich environments. We discuss how this finding could reshape our understanding of Mars's geochemical timeline and its core formation process.High-Performance Infrared Nano AntennasScientists have developed innovative gold nano antennas that significantly enhance the capabilities of thermal infrared cameras, improving image quality and sensitivity. This advancement, led by researchers at Sandia National Laboratories, allows for clearer observations of thermal infrared radiation, with applications ranging from astronomy to national security. We explore the technology behind these nano antennas and their potential impact on various fields.www.spacetimewithstuartgary.com✍️ Episode ReferencesNature Communicationshttps://www.nature.com/ncomms/American Astronomical Societyhttps://aas.org/Sandia National Laboratorieshttps://www.sandia.gov/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is Space Time Series 28, Episode 74 for broadcast on 20 June 202501:00 Record-breaking cosmic structure discovered12:15 A new approach to building Mars22:30 High-performance infrared nano antennas30:00 Science report: New dinosaur species discovered

From collagen powders to $100 creams, the skincare industry thrives on promises. However, many of the products we rely on for younger, healthier skin are built on shaky evidence. In this episode, world-renowned dermatologist Professor John McGrath breaks down what's real and what's not. We explore how skin truly ages, what happens beneath the surface, and why some popular treatments don't do what they claim. John dismantles three of the biggest myths in skincare, including the truth about SPF, collagen, and “bio-active” ingredients that never make it past the top layer of your skin. Professor McGrath is a Professor of Molecular Dermatology at King's College London and editor of the British Journal of Dermatology. His research has transformed how we understand genetic skin disorders and vitamin D's role in skin health. This conversation is packed with surprising insights - and one daily step that really does support healthier skin as you age.

Minecraft is a movie and a very popular video game with iconic block graphics that characters can "mine" for building material and gems. It's also what cognitive scientist Charley Wu and his team utilized to study how people learned as they played. Their unique study focused on both individual and social learning — and they found a clear answer to which players were most successful. (Hint: Get you a player who can do both.) Their results were published recently in the journal Nature Communications. Want to hear more about new science research?
