Aufnahmestopp von ausländischen Studierenden – so lautet das Verbot der US-Regierung an die Universität Harvard. Das könnte fatale Folgen für die Wissenschaft haben, warnt Christina Warinner, Professorin an der Elite-Universität. Pyritz, Lennart www.deutschlandfunk.de, Forschung aktuell
Christina Warinner, Professor of the Social Sciences in the Harvard Department of Anthropology and Sally Starling Seaver Associate Professor at the Radcliffe Institute, has uncovered lost stories about the ancient Maya city of Chichén Itza. With techniques like ancient DNA, isotopes and bioarchaeology, she and an international team of genetic scientists have made some startling discoveries that contradict the myth of sacrificed virgins—the offering of little boys, particularly twins.

Guest Lisa Caywood Panelists Richard Littauer | Amanda Casari Show Notes Hello and welcome to Sustain! The podcast where we talk about sustaining open source for the long haul. We're very excited for our guest today! Joining us is Lisa Caywood, who's the Senior Principal Community Architect at Red Hat OSPO, and has a podcast about cheese, which we'll learn a little more about. Today, our discussion revolves around managing open source communities, determining their strategic value, and gracefully ending relationships when necessary. We'll also hear about telco industry's shift towards open source code, and the importance of community health and strategic alignment with Red Hat's objectives in deciding whether to continue investing in a particular community. Also, there's a discussion on the challenges of managing relationships between corporations and open source projects. Download this episode to hear much more! [00:01:32] Lisa shares that Red Hat's OSPO focuses on outbound open source engagement, ensuring healthy and well-governed communities, and advising on engagement strategies. She tells us what a Senior Principal Community Architect does. [00:04:04] Lisa emphasizes the importance of community health and strategic alignment with Red Hat's objectives in deciding whether to continue investing in a particular community. [00:05:59] The discussion revolves around managing open source communities. [00:08:15] We hear the challenges of parting ways with communities, and Lisa offers insights into managing both individual and corporate transitions. [00:15:06] Lisa explains the challenges of managing relationships between corporations and open source projects. [00:17:30] One key issue is how to communicate with project leaders about sponsorship or support, which requires a nuanced approached. [00:19:37] Networking and telco are discussed as examples of industries where open source communities play a crucial role. Lisa touches on the need for projects to address interoperability pain points and ensure the different pieces of the stack are able to talk to each other in a cohesive way. [00:22:31] Lisa discusses the telco industry's shift towards open source code, with AT&T leading the way bringing a big chunk of their proprietary project into the open source world, and she mentions the ONAP project. [00:27:02] The scale of projects and problems being tackled in the telco industry is talked about since it's so exciting to Lisa, who has always been a big-picture person. [00:31:30] Lisa talks about when leaving a community, it's important to document and take the knowledge and mindset shift towards open source with you to the next community. [00:32:37] Find out about Lisa's podcast and where you can follow her on the web, Quotes [00:07:13] “The individual has to decide it's time to leave, but the company also to decide it's time to leave. Those are two different levels of how to say goodbye.” [00:09:39] “If you're an individual who's coming to the project leadership with a proposal or a plan for how you hand things off to other people, is the best thing you can do.” [00:16:06] “It's more how do I address the feeling and continue to make the sale. That's a different personality and different skillset.” [00:20:02] “It took a long time for Kubernetes to understand that there's a little wire on a diagram that connects your apps and that helps different components talk to each other and that's called the network. You need to include networking people in your community to make this all work and it eventually got there.” [00:21:44] “The number one thing that keep telcos awake at night is I can't have anything break. The conversations that we have with these companies span many different communities because we're not talking about one single type of technology.” [00:23:49] “We're all moving towards the same basic model. We're all going to be doing 80% of this stuff, so let's figure it out together.” [00:26:02] “The scale of Chinese telcos dwarfs AT&T in terms of number of users.” [00:30:56] “As a software person in a hardware company, you're always the odd duck out.” [00:32:05] “It's important not just as individuals, but as a company to be conscious of what you've learned in a community, perhaps documented that these are the useful things that we got from working in this community. Let's make sure we take that with us into our next community so we can take the best things forward.” Spotlight [00:34:03] Amanda's spotlight is a research paper, Name-based demographic inference and the unequal distribution of misrecognition (2023). [00:34:56] Richard's spotlight is the Master and Commander series. [00:35:21] Lisa's spotlight is Christina Warinner, who looked at gut microbiomes of nomadic herds in Mongolia, which helps from a cheesemaking perspective.

EPA Proposal To Require 60% Of New Cars To Be EVs by 2030 The EPA released a set of proposals this week that would cap C02 emissions for new cars. In order to meet the new stricter targets automakers would need to ramp up electric vehicle manufacturing substantially. By 2030, 60% of new cars would need to be electric. Ira talks with Casey Crownhart, Climate Reporter for the MIT Technology Review, about the new EPA emissions proposals and other top science news of the week including predictions of a bad mosquito season and turtles basking in the moonlight. Lactose Intolerance May Have A Lot To Do With Your Gut Microbiome In the animal kingdom, it's not normal to drink milk past infancy. It's even more rare to consume milk from another mammal. But throughout history, humans have used dairy farming as a way to get calories and nutrition from creatures like cows, goats, and sheep. And a big perk: dairy products taste good. Evidence of dairying goes back to the early Neolithic era. Traces have been found in the historical record in Europe, Asia, and Africa, in ancient teeth and pottery. Lactase persistence, or the ability to consume dairy into adulthood, developed alongside this burgeoning industry. But here's the catch: a large part of the population is still lactose intolerant, either from childhood or developed in adulthood. It's estimated that about a third of the U.S. population is lactose intolerant, with a higher chance among certain ethnic and racial groups. There's a lot to learn about the origins of lactose persistence and lactose intolerance, and much of that knowledge comes from the gut microbiome. Joining Ira to talk about this is Christina Warinner, assistant professor of anthropology at Harvard University, based in Cambridge, Massachusetts. Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
No dia 10 de maio, um artigo foi publicado na revista Science: Neanderthals carb loaded, helping grow their big brains | Science | AAAS (sciencemag.org) O estudo apenas afirmava que havia amido na dieta dos neandertais, baseado no fato de que bactérias que tipicamente vivem de açúcares foram encontrados nas placas dentárias dos mesmos. A autora principal, Christina Warinner, há anos critica a dieta paleolítica com base na falácia do espantalho, descrita na seguinte postagem: Ciência Low Carb: A falácia do espantalho (lowcarb-paleo.com.br) Sobre a ideia de que a glicose utilizada pelo cérebro precisaria vir da dieta: Ciência Low Carb: O cérebro não precisa de glicose? O jejum mais longo da história (lowcarb-paleo.com.br) E se descobríssemos que os homens do paleolítico comiam pão, o que mudaria nos resultados dos ensaios clínicos que provam a eficácia da estratégia low-carb para resolver os problemas do homem MODERNO?

Galileo’s Battle Against Science Denial Galileo Galilei is known as the father of observational astronomy. His theories about the movement of the Earth around the sun and his experiments testing principles of physics are the basis of modern astronomy. But he’s just as well known for his battles against science skeptics, having to defend his evidence against the political and religious critics and institutions of his time. In his new book Galileo and the Science Deniers, astrophysicist Mario Livio talks about the parallels of Galileo’s story to present-day climate change discussions, and other public scientific debates today. Monitoring Your Pandemic Health, From Your Home In recent weeks, the FDA has given the go-ahead to several tests for COVID-19 that can be performed remotely, from your own home. Such tests could help greatly expand testing capacity, an essential part of plans for recovery—but only if the tests are sensitive and reliable. Researchers are also working to develop other ways of using tech to monitor the outbreak, from heart rate monitors in smartwatches to sampling community sewage plants for evidence of the virus. Eric Topol, the founder and director of the Scripps Research Translational Institute, joins Ira to talk about some of the technology that could be brought to bear to get a better picture of the COVID-19 pandemic. The Origin Of The Feces For some researchers, nothing is more exciting than finding fossilized feces. These ancient poops are called coprolites, and they’re quite rare. Despite their less-than-glamorous-origins, each one is a gold mine of information about who left it behind. That’s because fecal fossils are a snapshot of the microbiome from which they came. Some researchers say studying these ancient records of diet and bacteria could help us learn about modern problems such as lactose intolerance and gut inflammation. Christina Warinner, assistant professor of anthropology at Harvard University in Cambridge, Massachusetts, joins Science Friday producer Kathleen Davis to talk coprolites, and what ancient feces can tell us about our ancestors, and ourselves.

This week we have two interviews from the annual meeting of AAAS in Washington D.C.: one on the history of food and one about our own perceptions of food and food waste. First up, host Sarah Crespi talks with Christina Warinner from the Max Planck Institute for the Science of Human History in Jena, Germany, about the history of dairying. When did people first start to milk animals and where? It turns out, the spread of human genetic adaptations for drinking milk do not closely correspond to the history of consuming milk from animals. Instead, evidence from ancient dental plaque suggests people from all over the world developed different ways of chugging milk—not all of them genetic. Next, Host Meagan Cantwell speaks with Sheril Kirshenbaum, co-director of the Michigan State University Food Literacy and Engagement Poll, about the public's perception of food waste. Do most people try to conserve food and produce less waste? Better insight into the point of view of consumers may help keep billions of kilograms of food from being discarded every year in the United States. This week's episode was edited by Podigy.

Brushing our teeth keeps them clean and free from debris, but back in medieval times, dental hygiene wasn't part of your daily routine. This means that scientists can look at the teeth of skeletons to reconstruct what food they might have munched on back then and find out more about their lifestyle. But recently a team of international scientists, lead from the Max Planck Institute for the Science of Human History in Jena, Germany, found something a little more peculiar fossilised in the teeth of a 1000 year old skeleton.

Massive Open Online Courses (MOOCs) provide free lectures and assignments, and gained global attention for their potential to increase education accessibility. Plagued with high attrition rates and fewer returning students every year, MOOCs have pivoted to a new revenue model—offering accredited master's degrees for professionals. Host Meagan Cantwell speaks with Justin Reich, an assistant professor in the Comparative Media Studies Department at the Massachusetts Institute of Technology in Cambridge, about the evolution of MOOCs and how these MOOC professional programs may be reaching a different audience than traditional online education. Archaeologists were flummoxed when they found a brilliant blue mineral in the dental plaque of a medieval-era woman from Germany. It turned out to be lapis lazuli—an expensive pigment that would have had to travel thousands of kilometers from the mines of Afghanistan to a monastery in Germany. Host Sarah Crespi talks to Christina Warinner, a professor of archaeogenetics at the Max Planck Institute for the Science of Human History in Jena, Germany, about how the discovery of this pigment shed light on the impressive life of the medieval woman, an artist who likely played a role in manuscript production.
