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.

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.
