Science Quickly

In this episode of Science Quickly, Andrea Thompson, senior desk editor for life sciences at Scientific American, joins host Kendra Pierre-Louis to discuss the recent heat wave in parts of the U.S. We’ll also dive into a recent district court ruling against a decision by the Trump administration to overhaul the Centers for Disease Control and Prevention’s recommended childhood vaccine schedule. Plus, we look at new research about unsafe levels of lead in kids’ clothing.

In this episode of Science Quickly, author Andy Weir joins SciAm’s Bri Kane to talk all things Project Hail Mary—from working with Ryan Gosling on the new film adaptation of the book to building the extraterrestrial character Rocky’s alien world and blending real science with playful fiction. And Weir explains why he himself would never volunteer for a space mission.

In this episode of Science Quickly, Scientific American’s associate health editor Lauren Young joins host Kendra Pierre-Louis to talk about how the story of GLP‑1 drugs such as Ozempic, Wegovy and Mounjaro is evolving. We trace GLP-1s’ origins as type 2 diabetes treatments, their rise as blockbuster weight‑loss medications and the ensuing complications—including the expanding market for compounded drugs. And we look at how the landscape has only grown more complex as researchers explore surprising potential uses for GLP‑1s, from addiction treatment to cardiovascular benefits, even as new concerns emerge about long‑term effects.

The U.S. Department of Health and Human Services is responsible for protecting the health of the American people. But over the past year, it has taken several steps that critics say undermine that very objective. In today’s episode of Science Quickly, we take a close look at the man at the center of those actions—Secretary of Health and Human Services Robert F. Kennedy, Jr.—who’s spent several years sowing confusion over vaccines and propping up fringe health theories. His beliefs, some critics say, echo “soft eugenics.” SciAm senior editor Dan Vergano, Ars Technica senior health reporter Beth Mole and historian Robert Johnston join host Kendra Pierre-Louis to unpack RFK, Jr.’s ideology and its repercussions on Americans’ health.
