Harness the power of genetics to keep your family safe, with Orchid. Check them out at orchidhealth.com. On this episode of Unsupervised Learning Razib talks to Penn State astrophysicist, Steinn Sigurdsson. Sigurdsson was a one-time colleague at the ScienceBlogs website in the twenty-aughts with Razib, where he ran the astrophysics-themed Dynamic of the Cats blog. At its peak, ScienceBlogs had nearly 100 writers who commented on topics as diverse as agriculture, Creationism and cosmology. Originally from Iceland, Sigurdsson's professional accomplishments have been wide-ranging, from serving as scientific director of arXiv to directing an institute focused on exobiology. Razib first asks him about the history of arXiv, which goes back over 30 years. It was the preprint server that blazed the bath for bioRxiv in biology, medRxiv in medicine and PsyArXiv in psychology. Razib asked Sigurdsson if preprint servers lead to open science, and if they will do away with peer preview. Do they affect the winner-take-all dynamics that apply to scientific publications? Razib and Sigurdsson also discuss the threat and promise of papers generated with AI methods like “large language models” pioneered by Google and popularized by OpenAI, and that have finally caught up to human-level fluency within the last 9 months with ChatGPT. Then Razib queries Sigurdsson on numerous astrophysical topics. Is the universe going to expand forever? (Probably, and that expansion is speeding up.) Do we understand most of the matter and energy in the universe? (No.) Sigurdsson also discusses in detail the fact that now in 2023 we have confirmed black holes empirically in a manner that couldn't have been imagined a generation ago. Additionally, Razib has to confront the possibility that physics might abandon causality, and even open the door to magic, within the twisted maze of their equations in order to make sense of the universe. Finally, they discuss the probability of other life in the universe if our solar system is representative, the probability of intelligent life, how many planets there are in the universe and the possibility of Dyson (or Musk?) spheres in our solar system in the future.

Ethan Siegel is a theoretical astrophysicist and science communicator. He received his PhD from the University of Florida and held academic positions at the University of Arizona, University of Oregon, and Lewis & Clark College before moving on to become a full-time science writer. Ethan is the author of the book Beyond The Galaxy, which is the story of “How Humanity Looked Beyond Our Milky Way And Discovered The Entire Universe” and he has contributed numerous articles to ScienceBlogs, Forbes, and BigThink. Today, Ethan is the face and personality behind Starts With A Bang, both a website and podcast by the same name that is dedicated to explaining and exploring the deepest mysteries of the cosmos.

“Real experts are wrong and will admit that they're wrong. Actually one of the ways that you can identify an expert is, you can search them admitting to being wrong at some point in time. Because, you know, people who are never wrong aren't experts, they're jerks.” - Dr. Mark Hoofnagle  In episode 168, Master Certified Coach Jill Farmer welcomes Dr. Mark Hoofnagle to the podcast. Dr. Hoofnagle is assistant professor of surgery in the section of Acute Critical Care Surgery at the Washington University in St Louis. He has been writing about critical thinking and science denialism since 2007. In this episode, he explains the many ways that the public is duped by misinformation, why people are so susceptible to misinformation and what, as doctors, we can do when our patients believe something other than the correct science. He also gives us tips for meaningful communication with patients or anyone in our lives who may be misinformed. Mark Hoofnagle MD/PhD trained at University of Virginia School of Medicine for medical school, University of Maryland Medical Center for General Surgery and University of Pennsylvania for Trauma and critical care and is now assistant professor of surgery in the section of Acute Critical Care Surgery at the Washington University in St Louis. He researches Deep Venous Thrombosis in trauma and gun violence at Washington University, and has written about critical thinking and denialism since 2007. His essay on “What is Denialism” on Scienceblogs from 2007 created framework for understanding the public dissemination of anti-science narratives, has been cited in the International Journal of Public Health and Nature, and provides context for understanding current disinformation and misinformation campaigns.   You can read his essay here and you can follow him on Twitter here Find full transcripts of DocWorking: The Whole Physician Podcast episodes on the DocWorking Blog  DocWorking empowers physicians and entire health care teams to get on the path to achieving their dreams, both in and outside of work, with programs designed to help you maximize life with minimal time.   Are you a physician who would like to tell your story?

Especial de fim de ano do Espaço Recíproco com um dos principais nomes de 2020! Estamos vivendo um momento complicado por diversos motivos. Passamos o ano de 2020 todo tendo nossas vidas modificadas devido à pandemia do Covid-19. Ainda, estamos passando por uma onda de descrença e de desvalorização da ciência. Por que isso está acontecendo? Quais os motivos que levam várias pessoas a ignorarem os fatos e acreditarem em ideias que divergem das pesquisas? A divulgação científica nunca foi tão essencial. É necessário fazer com que a ciência ultrapasse os muros da vida acadêmica e alcance todos os âmbitos da sociedade. Atila Iamarino é um divulgador científico desde a faculdade. Tem graduação em Ciências Biológicas Integral pela Universidade de São Paulo (USP). Doutorado em Ciências Biológicas (Microbiologia) também pela USP. Pós-doutorados feitos na USP e na Universidade de Yale, em New Haven, Connecticut. Criou o blog Rainha Vermelha e é fundador da maior rede de blogs de ciência do Brasil, o Science Blogs. Faz parte do Nerdcast e do Nerdologia, além de produzir vídeos para seu próprio canal no YouTube, o qual ganhou muita visibilidade ao longo da pandemia, devido às lives relacionadas a análises de acordo com a evolução do coronavírus e à criação das vacinas. A conversa da semana do Espaço Recíproco com Atila Iamarino abordou, dentre outros assuntos, a importância de uma comunicação de ciência efetiva e repetitiva, não só pelos divulgadores de ciência, mas também pelos cientistas e políticos. Só assim é possível combater a "imunidade ideológica" daqueles que não querem acreditar na realidade que se impôs. --- This episode is sponsored by · Anchor: The easiest way to make a podcast. https://anchor.fm/app

Gudrun unterhält sich in dieser Folge mit Lennart Hilbert, dem Leiter des Hilbert Labs am KIT. Das Labor ist Teil des Instituts für Toxikologie und Genetik (ITG), einem multidisziplinären Zentrum für biologische und chemische Forschung am KIT. Lennart Hilbert ist außerdem Juniorprofessor für Systembiologie/Bioinformatik am Zoologischen Institut des KIT. Das Thema von Lennarts Gruppe ist Computational Architectures in the Cell Nucleus. Das kann man auf zwei unterschiedliche Arten interpretieren. Einerseits untersucht Lennarts Gruppe den räumlichen Aufbau des Zellkerns mit Hilfe von Computern. Es heißt aber auch dass man aufgrund der dabei gewonnenen Erkenntnisse als Fernziel Datenverarbeitung mit Hilfe des Zellkernes als Informationsspeicher ermöglichen will. Gudrun und Lennart haben sich im Rahmen eines Treffens des KIT-Zentrums MathSEE kennengelernt, das im letzten Gespräch vorgestellt wurde. Mit der Hilfe von Super Auflösungs Mikroskopie schauen Lennart und seine Gruppe in das Innere von Zellkernen und sehen dabei dreidimensionale Bilder. Diese Bilder gleichen sie mit den Ergebnissen von den bisher standardmäßig durchgeführten Sequenzierexperimenten von Molekularbiologen ab. "Sehen" erfolgt mit empfindlichen Digitalkameras, deren Bilder geeignet gefiltert werden. Dabei ist eine einschränkende Randbedingung, dass die betrachteten Samples gegen Licht empfindlich sind, aber Licht für die visuelle Darstellung unabdingbar nötig ist - je kleiner die Details, desto mehr Licht. Man kann sich unschwer vorstellen, dass zur Bearbeitung diese Art von Fragen Informatik, Physik, Biologie und Mathematik nötig sind. Damit sich im Rahmen der Zusammenarbeit alle einbringen können, ist es hilfreich, wenn die Methoden einfach und die Ergebnisse visuell unmittelbar verständlich sind. Eine Grundannahme ist, dass die räumliche Organisation im Zellkern den Informationsflüssen aus der DNA-Sequenz entspricht. Die treibende Frage ist: Wie funktioniert Gensteuerung? Der betrachtete Regelkreis ist, dass die DNA als Bibliothek funktioniert. Aus einem Teil wird eine RNA-Kopie erstellt, sodass bestimmte Proteine hergestellt werden können. Diese Eiweiße aber steuern anschließend, welche Teile der DNA als nächstes gelesen werden (das schließt den Regelkreis). In der Systembiologie untersucht man dies bisher in Form von Differentialgleichungssystemen auf einer Metaebene. Wie das aber passiert ist aber noch relativ unklar. Die Hoffnung ist: Neues Sehen hilft hier, neues zu lernen und hierfür ist neueste Technik hilfreich. Die Molekulare Ebene ist der Teil der Biologie, wo im Moment am meisten Neues passiert. Lennart hat in Bremen Physik studiert und anschließend an der McGill University in Montréal in Physiologie promoviert. Hier hat er zum ersten Mal zwischen Theorie und Experiment in zwei Gruppen gleichzeitig gearbeitet. In Dresden am Zentrum für Systembiologie (Max Planck Institut für Molekulare Zellbiolgie und Genetik und Max Planck Institut für die Physik komplexer Systeme) konnte er als Postdoc weiterhin interdisziplinär arbeiten. Seit 2018 ist er am KIT tätig. Lennart und seine Gruppe arbeiten mit Zebrafischen, Bakterienstämmen, Zeitreihenanalyse und anderen mathematischen Modellen. Sie benötigen hoch parallele Simulationen und Machine Learning (z.B. um Mikroskopie-Daten zu entrauschen und mehr Farben gleichzeitig darzustellen). Lennart drückt es im Gespräch so aus: "Ich hab keine Disziplin mehr, ich habe nur noch Fragen." Die beiden Teile seiner Arbeit unterscheiden sich stark: Im Labor sind Gruppentreffen nötig, weil alle aufeinander angewiesen sind. Es wird viel geredet und präzise Handarbeit ist wichtig. In der theoretischen Arbeit ist man auf sich selbst angewiesen und es gibt weniger Interaktion. Any doubts #activematter is a relevant framework to understand nuclear and chromatin organization? Please look at this time-lapse.

Bill Donohue is not known for being passive and compliant. As President of the Catholic League, he has staunchly defended the Catholic Church with the delicacy of a pit-bull. And many on the left have felt his bite. Whether it's in the newspapers, television, movies, radio or any other platform, Bill Donohue's roar can be heard sniping at the powers that be who malign Catholicism and/or Catholics.  His newest book, "Common Sense Catholicism: How to Resolve Our Cultural Crisis," "analyzes how the three key elements of a democratic society--freedom, equality, and fraternity--have been misconstrued by intellectuals and policy makers who do not respect the limitations of the human condition."  I've known Bill for a decade or more. And what I found is many people underestimate his knowledge and intellect. He's has a doctorate in sociology and has written eight books. He has what seems boundless energy, which is good because there are many who attack him and want to bring him down, including Scienceblogs.com which once called him "an evil little man".  Our conversation on Lighthouse Faith podcast focuses on the latest cultural controversies including the sex abuse crisis in the Catholic Church and Pennsylvania State lawmaker Brian Sims' verbal attack on a pro-life woman praying in front of a Planned Parenthood clinic. It's never a dull moment when talking with Bill Donohue!

Science-Blogs und -Kanäle gibt es viele. Aber meistens sind sie naturwissenschaftlich. Warum du mit deinem Blog einen Beitrag dazu leisten solltest, dass auch die Geisteswissenschaften als gesellschaftlich relevant wahrgenommen werden, dafür nenne ich dir in der heutigen Folge 5 Gründe.

http://ikonokast.com/wp-content/uploads/2017/11/Echo-Skills-Red-Rocks-and-ScienceBlogs.mp3 Mike and Greg converse on the subject of the geology and geography of Arizona and the red rocks of Sedona. The rocks tell the story of the ages of the earth, and this is a pretty chapter. We also talk about the end of ScienceBlogs, which has been a seminal collective that set the tone in many ways for a new means of science communication through social media. And finally, Greg interviewed Shanthan Kesharaju, who has created an Amazon Echo Skill to tutor in mathematics. There are implications for the future of how we use adaptive systems to teach skills and develop our minds, with the possibility of staving off dementia in patients as well.

http://ikonokast.com/wp-content/uploads/2017/09/0015-John-McKay-Discovering-the-Mammoth.mp3 In the podcast, you may hear Mike refer to John as a "Vulcan Historian." What Mike meant to say is that John J. McKay is a historian with a specialty in the history of the Balkans, and that is an important distinction. He is also interested in the many weird theories that abound to explain (often not very well) natural history of the earth. He discovered that the mammoths are used as ersatz evidence in many of those theories, such as the idea that the ice build up at the poles became so heavy that the poles slid southward 40 degrees latitude and that pushed Atlantis to where Antarctica now freezes. There were many other strange ideas to explain the discovery of these giant bones and Mr. McKay relates how the process of discovering the mammoth is important to the development of science itself.

原创 原理 2017-03-05 11:11科技最前沿，主要从丘孔语论比较感兴趣的几个领域来谈论科学科技，可能涉及天文、物理、互联网/IT、人工智能/Ai、数码/手机、编程、大数据、商业大佬、创新创业创客、化学、医学、养生、心理学、灵性等领域；认识天地，开阔思维，重塑自我。不要说我涉猎太广泛，只是人生认识自我的过程太过漫长，我们只能先广纳外，然后求诸内，探索着，迷茫着。微信扫码，可以关注公众号丘孔语论，期望与你做更深的交流。有一天，七岁的小明找我聊天，他经常会问我各式各样的科学问题，通常我也能够应付他提出来的许多看似简单的基础问题。但这天，他若有所思后，开始发起讨人厌的连续式发问：我很好奇，你、我以及所有人类是由什么构成的？人类是由肌肉、骨头和器官构成的。那么器官又是由什么构成的？器官是由细胞构成的。细胞是由什么构成的？细胞是由细胞器构成的。细胞器又是由什么构成的？它们是由蛋白质构成的。蛋白质又是由什么构成的？是由氨基酸构成的哦。那么氨基酸呢？它们是由原子构成的。原子又是由什么构成的？原子是由质子、中子和电子构成的。电子是由什么组成的呢？电子是由电子场构成的。那么电子场是由什么构成的？……这是我所能告诉小明的极限。但是，等等......听到电子场我想有许多人都会好奇，难道电子不是最基本的粒子吗？怎么还有电子场？的确，当科学家跟非科学专业的人讲解粒子物理学的时候，他们通常都会从分子、原子一直到说到无法再分割的基本粒子。这也是大多数人所熟知的。△ 夸克是已知的基本粒子，但是科学家正在寻找它们是否由更小的粒子构成。（图片来源：Fermilab）这是看待事物的一种方式，但不是最真实的。也许你还记得在2012年的时候，科学家找到了被称为上帝粒子的希格斯玻色子，即使你不是科学家，也会被当时的氛围所感染。但如果你要想能够真正的欣赏到希格斯玻色子的发现，那么你就需要知道的更多。要想知道到底发生了什么，你就必须要放弃粒子的概念。而是要把粒子想象成场。△ 磁场。（图片来源：Windell Oskay）场，你应该很熟悉了。当把两个磁铁慢慢靠近在一起的时候，即使它们没有碰到对方，也会感受到彼此的吸引力或排斥力——即两个磁场间的相互作用。同样地，当你向空中跳起来的时候，你会重新回到地面上。那是因为你生活在地球的引力场。事实是，每一个你所知道的粒子，其实都是一个场。宇宙中充满了场，比如夸克场、电子场、中微子场、光子场和希格斯场等等，而我们所认为的粒子只是这些场的“激发态”（或者说是场的局域振动），就像海洋中的波。比如，一个电子只是电子场所激发出来的：△ 粒子是场的激发态，或说场的局域振动。（图片来源：Fermilab）虽然这跟你以前知道的很不一样，但以场的角度去看待这个世界，实际上使粒子物理学的一些混淆概念变得更清晰明朗。举个例子，当一个放射性物质衰变的时候，我们通常把这想象成分离出不同的粒子。比如中子会衰变成质子、电子和反中微子。听起来好像是质子、电子和反中微子隐藏在中子里面，等待破茧而出，但并不是这样。可是，当中子衰变时，它们就出现了。△ 自由中子的半衰期大约是611秒，衰变成质子、电子和反中微子。（图片来源：Scienceblogs.com）如果我们从场的角度去思考，这些突然出现的新粒子就开始变得说得通了。举个更简单的例子，一个电子突然辐射出一个光子：△ 电子辐射出光子。（图片来源：Fermilab）这里，电子场的能量传递给了光子场，激发了光子场的局域振动，看起来就像是电子辐射出了新粒子，然后开始相互远离。场的概念也帮助我们理解科学家是如何在大型强子对撞机（LHC）中制造出大质量粒子，比如希格斯玻色子。科学家在两束LHC将两束高能的质子束撞在一起，并研究它们的对撞结果。△ 通过对撞质子束，会产生出大质量的希格斯玻色子。（图片来源：CERN/AP）通常，这个过程被比喻成将两块手表使劲地撞在一起，通过被撞的四处飞散的所有手表零件来研究手表是怎么工作的。这其实是个很差的比喻，主要的原因是当你把粒子撞在一起的时候，实际跑出来的并不是原来粒子内部的粒子。真正发生的就好比是你将斯沃琪手表撞在一起，结果出来的是伯爵手表。真正发生在LHC对撞的是场的激发态——高能的质子——在一起振动并将它们的能量转移到邻近的场，产生新的激发态，也就是我们所看到的新粒子，比如希格斯玻色子。场也能够更好的解释希格斯机制。希格斯玻色子本身并不赋予其它基本粒子质量，真正赋予质量的是希格斯场与其它场之间的作用。希格斯玻色子或许是媒体的宠儿，但真正的明星却是希格斯场。场的概念解释了宇宙更深层次和基本层面是如何运作的。而这背后的理论则被称为“量子场论”。大部分人可能更加熟悉的是量子力学和狭义相对论，这两个都是100年前左右提出的理论。但即使是在今天，当你第一次接触到的时候也会为它们的许多预言感到困惑。但真正精彩的其实是量子场论，它是量子力学和狭义相对论的结合。

No podcast desta semana Silmar, Ronaldo e Estrela (sim, ela se chama assim mesmo :-) lançam o segundo episódio do #SciCast Entrevista, onde são entrevistados cientistas de verdade, que nos contam um pouco sobre a realidade da pesquisa no Brasil. A convidada especial deste programa é Fernanda Poletto (@balamagica), graduada em Farmácia, com mestrado em Ciências Farmacêuticas e Doutorado em Química, Professora Adjunta na Universidade Federal do Rio Grande do Sul (UFRGS), que também escreve no Bala Mágica do Science Blogs. Atualmente a Fernanda trabalha no Instituto de Química, no Departamento de Química Orgânica da UFRGS, onde desenvolve sua pesquisa sobre a síntese de novos elementos surfactantes e, a partir destes, a construção de materiais estruturalmente complexos, conhecidos como cristais líquidos liotrópicos. Aproveitem e conheçam o amigo hidrofóbico.

No episódio desta semana do podcast sobre ciência mais divertido da internet brasileira (rá), Silmar, Jorge, Ronaldo e Carol (equipe #SciCast) estreiam um novo formato de programa, o #SciCast Entrevista, onde serão entrevistados cientistas de verdade, que nos contarão um pouco sobre a realidade da pesquisa no Brasil. A convidada especial deste programa é a bióloga Natália Dörr (@NataliaDorr), mestranda em Genética e Biologia Molecular pela Universidade Federal do Rio Grande do Sul (UFRGS), que escreve também no Crônica das Moscas do Science Blogs. Atualmente a Natália trabalha no Laboratório de Drosophila, do Departamento de Genética da UFRGS, onde desenvolve sua pesquisa sobre a relação simbiótica estabelecida entre a bactéria Endossibionte Wolbachia e as moscas do subgrupo Willistoni de Drosophila (aquela com olhos vermelhos). Aproveitem e conheçam um pouco sobre as bactérias feminazi.

Será a emoção mais forte do que a razão? Esta semana Silmar Geremia, Jorge Costa, Ronaldo Gogoni e Matheus Gonçalves (equipe #SciCast) unem-se aos pesquisadores Tatiana Nahas (@ciencianamidia e Ciência na Mídia) e Rafael Soares (@Rafael_RNAm e RNAm no ScienceBlogs) na luta contra a desinformação que se espalha quando o assunto são testes científicos em animais. Divirta-se com a mais louca leitura de e-mails, emocione-se com os depoimentos comentados neste episódio e, se por acaso avistar algum maluco de cueca box adentrando o seu laboratório, Fuja para as Montanhas!

Host: Karen Stollznow Our guest this week is Josh Rosenau, the Programs and Policy Director of the National Center for Science Education (NCSE), and writer of the blog "Thoughts from Kansas" at ScienceBlogs. Josh has pursued a doctoral candidate at the University of Kansas, studying the ways ecological competition shapes the ecological niche and geographical ranges of species. In his role at the NCSE, he works with grassroots groups, testifies before school boards, meets with legislators, works with scientists to be more effective communicators and the public to increase science literacy globally. In this interview with Karen Stollznow, Josh presents the "Three Pillars of Creationism", the beliefs and claims of creationists. He describes their rhetoric and propaganda, and the setbacks they cause for science, from legal cases to creationist theme parks. Josh also talks about some recent successes for science. The NCSE works tirelessly to battle creationists and improve the public understanding of evolution. But this is an organization that aims to "go out of business", and where the staff members ultimately aim to be out of their jobs.

To celebrate the 200th birthday of Charles Darwin Ed Brayton, author of ScienceBlogs popular blog Dispatches from the Culture Wars, joins us to talk about his new radio show and podcast Declaring Independence. He shares with us a fascinating interview with Ken Miller, critic of Intelligent Design and author of the new book Only a Theory. Miller explains the findings of a paper that was devastating to the notion of irreducible complexity, a paper written by none other than Intelligent Design advocate Michael Behe. Reasonable Doubts: Your skeptical guide to religion offering news and commentary of interest to skeptics, atheists, humanists, apologists looking for a challenge and freethinkers of all persuasions.

In this episode, we chat with PZ Myers - lead author of the blog Pharyngula (Pharyngula is hosted at Science Blogs - a project from Seed Magazine). Myers is a biologist and associate professor at the University of Minnesota, Morris. Contact Information at UM Morris Curriculum Vitae Personal Page Profile on Nature Network Pharyngula Galleries Articles written by PZ Myers at Seed Magazine 2006 Weblog Award Winner: Best Science Blog Preview from the Show: Myers: What you want to do with a blog - it's such an informal medium - if you get all stuffy and treat it as something where you are going to write a formal treatise everyday, I don't think you'll get as much interest. So by keeping it personal, keeping it human, what I think I've done is open up a little window into a science professor's life, which is sometimes scary, but fun. Basler: Do you think that this type of casual communication [blogging] is something really important that the students are going to need in the future, or was it just an experiment to try out because you were blogging? Myers: Oh it's both. I mean, this is a brave new medium. I'm trying new things; I wanna explore this and see what we can do with our students. But I also think it's important for the future of science and science education - that what we want is active, involved learners at every stage of the game. And if this is a way that we can get people talking about science, then that's a huge step - that's important. Myers: My schedule's turning into a frightening thing; it's getting so packed full of requests to talk, but I try to indulge in as much as possible. Bartel: So you're working on Darwin Day instead of enjoying it, is what you're saying? Myers: Well, getting up in front of an audience and talking about evolution and talking about science, talking about philosophy in these ideas - that's not working is it?
