Scientific American

Host Rachel Feltman, alongside leading science and tech journalists, dives into the rich world of scientific discovery in this bite-size science variety show.

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. Finally, we’ll explore the new era of mega constellations as active SpaceX satellites orbiting Earth cross the 10,000 mark.

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.

Andy Weir spills the space tea on Ryan Gosling and Project Hail Mary

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.

GLP-1 drugs are entering a new chapter

In this episode of Science Quickly, we cover the record release of global emergency oil reserves amid escalating conflict, a breakdown of why nuclear experts say Iran was not close to building a nuclear weapon, new research that shows how climate change is increasing both the likelihood and size of severe hail and a study that reveals how aging gut microbiomes may impair cognitive function through the gut-brain connection.

Nuclear doubts, bigger hail, and new clues about aging brains

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.

How RFK, Jr.’s beliefs echo a troubling ideology

In this episode of Science Quickly, we dive into the psychology of deception through the deliciously twisty lens of The Traitors, exploring why humans are surprisingly bad at detecting lies and what science says about it. SciAm reporter Jackie Flynn Mogensen joins host Kendra Pierre-Louis to break down research on lie detection, reveal why physical tells are often misleading and explain how contestants use (or fail to use) strategies backed by behavioral science.

The Traitors and the science of sneaky lies

In this episode of Science Quickly, we cover a few important updates on the measles outbreaks in the U.S. We also look at how governments are increasingly turning to artificial intelligence for military action, including the recent U.S. airstrikes against Iran. Plus, we dive into a worrying new finding about the quickening pace of global warming. And finally, we explore the complex physics behind the delightful squeaks of basketball shoes.

Michael Pollan explores consciousness, AI and the brain

In February the BBC’s Thomas Germain became the world’s “best tech journalist at eating hot dogs”—at least, that’s what ChatGPT and Google Search’s “AI Overview” were telling Internet users for a while. Germain achieved this false glory with what he has called “the dumbest stunt” of his career. In this episode of Science Quickly, he joins host Kendra Pierre-Louis to talk about just how easy this was and how his simple—and hilarious—trick has exposed a serious flaw in common AI tools.
