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.

A new AI tool to decode DNA, a medical marvel and a rebel lipstick vine

In this episode of Science Quickly, we dive into Google DeepMind’s new artificial intelligence model AlphaGenome, which could help researchers better understand how noncoding DNA shapes gene expression. We also look at how doctors pulled off a medical marvel when they kept a man alive without lungs for two days. Plus, we learn how researchers cracked an evolutionary puzzle involving a peculiar flower.

The hidden genius behind nonreflective glass

In this episode of Science Quickly, host Kendra Pierre-Louis talks with Katie Hafner of the podcast Lost Women of Science about the remarkable but often overlooked physicist and chemist Katharine Burr Blodgett, whose pioneering work in early nanotechnology led to nonreflective glass. Hafner shares why the Lost Women of Science team devoted nearly a year to uncovering Blodgett’s full story and reflects on the broader mission to restore women to the scientific record.

Want to smell more attractive? Try these foods

Many people turn to expensive perfumes to elevate their natural scent and smell more pleasant to others. But what if you could achieve that just by switching up your diet? In this episode of Science Quickly, host Kendra Pierre-Louis talks with freelance journalist Sofia Quaglia about the science behind how what we eat can subtly change how we smell—and how attractive others perceive us to be. The conversation explores surprising findings about garlic and armpit odor, counterintuitive effects of meat intake on body scent and the strange, smelly experiments behind this research.

A historic moon mission, AI that helps restore stroke patients’ voice and the oldest cave art ever found

In this episode of Science Quickly, we look at the stakes behind Artemis II, NASA’s historic lunar flyby mission that’s preparing to launch soon. We’ll also dive into the science behind Revoice, an artificial-intelligence-powered wearable device that could help stroke patients with speech impairment communicate. Plus, we discuss how previously overlooked art on the ceiling of an Indonesian cave could rewrite the story of early human migration.

The quest for Leonardo da Vinci’s DNA

In this episode of Science Quickly, host Kendra Pierre-Louis speaks with forensic scientist Rhonda Roby about an ambitious effort to uncover traces of Leonardo da Vinci’s DNA using modern forensic techniques. Roby and her colleagues are carefully sampling centuries‑old artworks, working with extremely small amounts of biological material, to learn more about Leonardo himself and the history of his art while also advancing methods that could one day help authenticate artworks. The episode explores how forensic approaches typically used in criminal investigations are being applied to a 500‑year‑old historical puzzle.

What is consciousness, really?

In this episode, we explore what consciousness is, how the brain creates it and what current science says about dreams, anesthesia, animals and even artificial intelligence. Scientific American’s associate editor Allison Parshall breaks down what the leading theories are and why understanding our own awareness remains one of science’s toughest challenges.

EPA weakens air pollution rules, cancer survival soars, and NASA evacuates astronauts

In this episode of Science Quickly, we unpack the Environmental Protection Agency’s controversial decision to change how it calculates health benefits from regulating certain air pollutants, a move that experts warn could lead to dirtier air and worse health outcomes. And we’ve achieved a major milestone in cancer care, with five-year survival rates hitting a record high, but looming policy threats could stall progress. Plus, NASA’s first-ever medical evacuation from the International Space Station could offer lessons for future missions.
