Biorobots, The Math Of Life, Science Comics. Jan 17, 2020, Part 2

Living Robots, Designed By Computer Researchers have used artificial intelligence methods to design ‘living robots,’ made from two types of frog cells. The ‘xenobots,’ named for the Xenopus genus of frogs, can move, push objects, and potentially carry materials from one place to another—though the researchers acknowledge that much additional work would need to be done to make the xenobots into a practical tool. The research was published in the Proceedings of the National Academy of Sciences. Josh Bongard, a professor of computer science at the University of Vermont and co-author of the report, joins Ira to talk about designing cell-based structures and next steps for the technology.  The Math Behind Big Decision Making What does it mean for your health if a cancer screening is 90% accurate? Or when a lawyer says there’s a 99% chance a defendant is guilty? We encounter numbers in our everyday lives that can influence how we make big decisions, but what do these numbers really tell us?  Mathematical biologist explores these concepts and patterns in his book The Math of Life and Death: 7 Mathematical Principles That Shape Our Lives. He joins Ira to talk about the hidden math principles that are used in medicine, law, and in the media and how the numbers can be misused and correctly interpreted. The Science Comics Of Rosemary Mosco Have you ever wondered what a Great Blue Heron would write in a love letter to a potential mate? Or what the moons of Mars think of themselves? These are the scenes that nature cartoonist Rosemary Mosco dreams up in her comic Bird and Moon.   “Nature is really funny. It’s never not funny,” Mosco says in SciFri’s latest SciArts video. “You can go into the woods and find 20 or 30 hilarious potential comic prompts anywhere you go.” Viewers may come for the laughs, but they will end up learning facts, she explains. Mosco talks about her inspiration for finding the funny side of snakes, planets, and nature, and how she uses humor to communicate science.  Subscribe to this podcast.
