Two of the world’s most famous research chimpanzees have finally retired. Hercules and Leo arrived at a chimp sanctuary in Georgia last week. Sarah Crespi checks in with Online News Editor David Grimm on the increasing momentum for research chimp retirement since the primates were labeled endangered species in 2015.
Sarah also interviews freelancer Sophia Chen about her piece on x-ray ghost imaging—a technique that may lead to safer medical imaging done with cheap, single-pixel cameras.
David Malakoff joins Sarah to talk about the big boost in U.S. science funding signed into law over the weekend.
Finally, Jen Golbeck interviews author Stephanie Elizabeth Mohr on her book First in Fly: Drosophila Research and Biological Discovery for our monthly books segment.

Folge vom 22.03.2018A possible cause for severe morning sickness, and linking mouse moms’ caretaking to brain changes in baby miceResearchers are converging on which genes are linked to morning sickness—the nausea and vomiting associated with pregnancy—and the more severe form: hyperemesis gravidarum (HG). And once we know what those genes are—can we help pregnant women feel better? News intern Roni Dengler joins Sarah Crespi to talk about a new study that suggests a protein already flagged for its role in cancer-related nausea may also be behind HG. In a second segment, Tracy Bedrosian of the Neurotechnology Innovations Translator talks about how the amount of time spent being licked by mom might be linked to changes in the genetic code of hippocampal neurons in mice pups. Could these types of genomic changes be a new type of plasticity in the brain? This week’s episode was edited by Podigy. Listen to previous podcasts.

Folge vom 15.03.2018How humans survived an ancient volcanic winter and how disgust shapes ecosystemsWhen Indonesia’s Mount Toba blew its top some 74,000 years ago, an apocalyptic scenario ensued: Tons of ash and debris entered the atmosphere, coating the planet in ash for 2 weeks straight and sending global temperatures plummeting. Despite the worldwide destruction, humans survived. Sarah Crespi talks with Online News Editor Catherine Matacic about how life after Toba was even possible—were humans decimated, or did they rally in the face of a suddenly extra hostile planet? Next, Julia Buck of the University of California, Santa Barbara, joins Sarah to discuss her Science commentary piece on landscapes of disgust. You may have heard of a landscape of fear—how a predator can influence an ecosystem not just by eating its prey, but also by introducing fear into the system, changing the behavior of many organisms. Buck and colleagues write about how disgust can operate in a similar way: Animals protect themselves from parasites and infection by avoiding disgusting things such as dead animals of the same species or those with disease.

Folge vom 08.03.2018Animals that don’t need people to be domesticated; the astonishing spread of false news; and links between gender, sexual orientation, and speechDid people domesticate animals? Or did they domesticate themselves? Online News Editor David Grimm talks with Sarah Crespi about a recent study that looked at self-domesticating mice. If they could go it alone, could cats or dogs have done the same in the distant past? Next, Sinan Aral of the Massachusetts Institute of Technology in Cambridge joins Sarah to discuss his work on true and false rumor cascades across all of Twitter, since its inception. He finds that false news travels further, deeper, and faster than true news, regardless of the source of the tweet, the kind of news it was, or whether bots were involved. In a bonus segment recording during a live podcasting event at the AAAS Annual Meeting in Austin, Sarah first speaks with Ben Munson of the University of Minnesota in Minneapolis about markers of gender and sexual orientation in spoken language and then Adrienne Hancock of The George Washington University in Washington, D.C., talks about using what we know about gender and communication to help transgender women change their speech and communication style. Live recordings sessions at the AAAS meeting were supported by funds from the European Commission. This week’s episode was edited by Podigy. Listen to previous podcasts.
