Science: Cloning Saves An Endangered Species And Exoplanet ‘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.

Astronomy: What’s Inside An Exoplanet? (Video)

Out in the vast universe, unknown billions of strange worlds drift around other stars. Many of them are quite unlike anything in our solar system. While astronomers hope to use immense upcoming observatories to get a better look at their outsides, Federica Coppari has been using the world’s largest laser to investigate their insides. Coppari compresses familiar substances, including rocks and water, into new forms. Her work has yielded insights into the inner workings of frozen giants such as Uranus and Neptune, as well as the potential habitability of super-Earths — rocky planets that dwarf our own.
