AI is everywhere these days, and though there’s debate about how useful it is, one area where experts think it could be game-changing is scientific research. It promised to be particularly useful for speeding up drug discovery, an expensive and time-consuming process that can take decades. But so far, it hasn’t panned out.The few AI-designed drugs that have made it to clinical trials haven’t been approved, venture capital investment in these efforts has cratered in the last few years, and many startups have shut their doors. So why has it been so hard to make AI-designed drugs? What are the fundamental issues, and what does the future of this research look like?Joining Host Ira Flatow with some answers is Peter Coveney, who studies how chemistry discoveries can be sped up with algorithms and computers.Guest: Dr. Peter Coveney is a professor and director of the Centre for Computational Science at University College London.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

It’s easy to take maps for granted. After all, most of us have a pretty good map in our pockets at all times, ready to show us how to get anywhere on the globe. But to make a map useful, you have to decide what to keep in and what to leave out—and, most importantly, which mathematical equations to use. Beyond navigating from point A to point B, math and maps come together for a wide variety of things, like working out the most efficient route to deliver packages, calculating the depth of the ocean floor, and more. Host Ira Flatow is joined by Paulina Rowińska, mathematician and author of Mapmatics: A Mathematician's Guide to Navigating the World, to go on a journey through the math at the heart of all kinds of maps. Guest: Dr. Paulina Rowińska is a mathematician, writer, science journalist and author of Mapmatics: A Mathematician's Guide to Navigating the World.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

It seems like every week, there’s a new headline about some kind of sci-fi-esque organ transplant. Think eyeballs, 3D-printed kidneys, pig hearts.In her new book, Replaceable You: Adventures in Human Anatomy, science writer Mary Roach chronicles the effort to fabricate human body parts—and where that effort sometimes breaks down. Host Flora Lichtman speaks with Roach about everything from hair transplants to 3D-printed hearts, and why our anatomy is so hard to replicate in the first place.Guest: Mary Roach is a science writer and the author of Replaceable You: Adventures in Human Anatomy.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
