    A window into live brains, and what saliva tells babies about human relationships
    On this week’s show: Ethical concerns rise with an increase in open brain research, and how sharing saliva can be a proxy for the closeness of a relationship Human brains are protected by our hard skulls, but these bony shields also keep researchers out. With brain surgeries and brain implants on the rise, scientists are getting more chances to explore living brains. Staff Writer Kelly Servick joins host Sarah Crespi to talk about the ethics of doing research on patients undergoing intense medical procedures, and the kinds of research being done. Also this week, Ashley Thomas, a postdoctoral researcher in the brain and cognitive science department at the Massachusetts Institute of Technology, talks about the meaning behind sharing saliva. Spend any time with a baby lately? Were you in awe—eager to cuddle, kiss, even change a diaper? Or were you slightly horrified by the drool and other fluids seeping out of this new human? Your feelings on the matter might depend on your closeness with the baby and—as Thomas and colleagues write this week in Science—the baby may notice which way you feel. According to their results, babies, like adults, seem to recognize sharing saliva—like sharing food and utensils or kissing—as a signal of close relationships.

    Cloning for conservation, and divining dynamos on super-Earths
    On this week’s show: How cloning can introduce diversity into an endangered species, and ramping up the pressure on iron to see how it might behave in the cores of rocky exoplanets First up this week, News Intern Rachel Fritts talks with host Sarah Crespi about cloning a frozen ferret to save an endangered species. Also this week, Rick Kraus, a research scientist at Lawrence Livermore National Laboratory, talks about how his group used a powerful laser to compress iron to pressures similar to those found in the cores of some rocky exoplanets. If these super-Earths’ cores are like our Earth’s, they may have a protective magnetosphere that increases their chances of hosting life. This week’s episode was produced with help from Podigy.

    Setting up a permafrost observatory, and regulating transmissible vaccines
    On this week’s show: Russia announces plans to monitor permafrost, and a conversation about the dangers of self-spreading engineered viruses and vaccines Science journalist Olga Dobrovidova joins host Sarah Crespi to talk about plans to set up a national permafrost observatory in Russia. Then Filippa Lentzos, senior lecturer in science and international security in the department of war studies and in the department of global health and social medicine, and co-director for the center for science and security at King’s College London, joins Sarah to discuss her Science commentary on the dangers of transmissible vaccines for controlling invasive species and viruses found in wildlife.   This week’s episode was produced with help from Podigy.

    Top online stories, the state of marijuana research, and Afrofuturism
    On this week’s show: The best of our online stories, what we know about the effects of cannabinoids, and the last in our series of books on race and science First, Online News Editor David Grimm brings the top online stories of the year—from headless slugs to Dyson spheres. You can find out the other top stories and the most popular online story of the year here. Then, Tibor Harkany, a professor of molecular neuroscience at the Medical University of Vienna’s Center for Brain Research, talks with host Sarah Crespi about the state of marijuana research. Pot has been legalized in many places, and many people take cannabinoids—but what do we know about the effects of these molecules on people? Tibor calls for more research into their helpful and harmful potential.  Finally, we have the very last installment of our series of books on race and science. Books host Angela Saini talks with physician and science fiction author Tade Thompson about his book Rosewater. Listen to the whole series. This week’s episode was produced with help from Podigy.
