Science Magazine Podcast
Weekly podcasts from Science Magazine, the world's leading journal of original scientific research, global news, and commentary.

Orla Smith, editor of Science Translational Medicine joins host Sarah Crespi to talk about what’s changed in the past 10 years of microbiome research, what’s getting close to being useful in treatment, and how strong, exactly, the research is behind those probiotic yogurts.

When you’re sick, sleeping is restorative—it helps your body recover from nasty infections. Meagan Cantwell speaks with Amita Sehgal, professor of Neuroscience at the University of Pennsylvania and an investigator at the Howard Hughes Medical Institute in Chevy Chase, Maryland, about the process of discovering a gene in fruit flies that links sleep and immune function.

The “dank” smelling terpenes emitted by growing marijuana can combine with chemicals in car emissions to form ozone, a health-damaging compound. This is especially problematic in Denver, where ozone levels are dangerously high and pot farms have sprung up along two highways in the city. Host Sarah Crespi talks with reporter Jason Plautz about [researchers’ efforts to measure terpene emissions]linkTK from pot plants and how federal restrictions have hampered them.

 

Next, host Meagan Cantwell talks with Dana Small, a professor of psychiatry and psychology at Yale University, about how processed foods are perceived by the body. In a doughnut-rich world, what’s a body to think about calories, nutrition, and satiety?

 

And in the first book segment of the year, books editor Valerie Thompson is joined by Erika Malim, a history professor at Princeton University, to talk about her book Creatures of Cain: The Hunt for Human Nature in Cold War America, which follows the rise and fall of the “killer ape hypothesis”—the idea that our capacity for killing each other is what makes us human.

It’s incredibly difficult to get an inkling of what is going on inside gas giants Saturn and Jupiter. But with data deliveries from the Cassini and Juno spacecrafts, researchers are starting to learn more. Science staff writer Paul Voosen talks with host Sarah Crespi about new gravity measurements from Cassini’s last passes around Saturn. Using these data, researchers were able to compare wind patterns on Saturn and Jupiter and measure the mass and age of Saturn’s rings. It turns out the rings are young, relatively speaking—they may have formed as recently as 10 million years ago, after dinosaurs went extinct.   

 

Megan Cantwell then talks to science writer Laura Spinney about how researchers are fighting conspiracy theories and political manipulation in the Democratic Republic of the Congo during the country’s ongoing Ebola outbreak. In a first, the government, nongovernmental organizations, and scientists are working with community leaders to fight misinformation—and they might actually be winning.

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.

Plan S, an initiative that requires participating research funders to immediately publish research in an open-access journal or repository, was announced in September 2018 by Science Europe with 11 participating agencies. Several others have signed on since the launch, but other funders and journal publishers have reservations. Host Meagan Cantwell speaks with contributing correspondent Tania Rabesandratana about those reservations and how Plan S is trying to change publishing practices and research culture at large.

 

Some 1.7 million Jewish people were murdered by the Nazis in the 22 months of Operation Reinhard (1942–43) which aimed to eliminate all Jews in occupied Poland. But until now, the speed and totality of these murders were poorly understood. It turns out that about one-quarter of all Jews killed during the Holocaust were murdered in the autumn of 1942, during this operation. Meagan talks with Lewi Stone, a professor of biomathematics at Tel Aviv University in Israel and mathematical science at RMIT University in Melbourne, Australia, about this shocking kill-rate, and why researchers are taking a quantitative approach to characterizing genocides.
