Humans are the only species that has chins. How this unique trait evolved has always been somewhat of a mystery. In this episode of Science Quickly, host Kendra Pierre-Louis talks to paleoanthropologist Lauren Schroeder, who co-authored a recent study that sheds light on the evolutionary riddle of the chin and the ways that evolution can sometimes occur unexpectedly.

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.
