First up on the podcast, Online News Editor David Grimm joins host Sarah Crespi for a rundown of online news stories. They talk about lichen that dine on dino bones, the physics of the lip-out problem in golf, and a brain-computer interface that can decode a tonal language (Chinese) from brain waves. Next on the show, Jeremy Munday, a professor of electrical and computer engineering at University of California, Davis, talks about generating mechanical power using a heat engine aimed at the night sky. Heat engines typically generate power by harnessing a temperature difference between two things—but by using space as the cold part and the ground as the warm part, Munday’s device can generate energy at night.
