The surprising enigma of slippery ice
Many of the events in the Winter Olympics involve some sort of sliding or slipping on ice—in a skillful, controlled way. Those moves often seem effortless, but the physics behind what makes them possible is messy. For centuries, scientists have been trying to figure out why ice is slippery. In this episode of Science Quickly, host Kendra Pierre-Louis laces up her skates to explore the slippery truth behind that deceptively simple question. She’s joined by science journalist Paulina Rowińska and physicists Daniel Bonn and Martin Müser, who take us through various competing theories and explain how we may finally have a winner.

The curious case of the nonburpers
Can you imagine not being able to burp at all? In this episode of Science Quickly, we dive into the little-known but surprisingly serious “no burp” syndrome known as retrograde cricopharyngeus dysfunction (RCPD). Otolaryngologist Robert Bastian, who co-authored the paper that first defined RCPD in 2019, explains what causes this unusual condition and how it can make daily life miserable. But relief can come from an unexpected source: a Botox injection that gives patients the chance to “learn” how to burp—an experience many describe as life-changing.
