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

With Valentine’s Day around the corner, kissing may be on your mind. But why do we kiss? In this episode of Science Quickly, evolutionary biologist Matilda Brindle joins host Kendra Pierre-Louis to uncover the evolutionary roots of kissing. We trace kissing back 21.5 million years and learn how it’s common among primates and what that tells us about how kissing may have evolved among humans. Plus, we also unpack recent findings that hint that humans and Neandertals may have once locked lips.

The evolutionary riddle of the kiss

In this episode of Science Quickly, hosts Kendra Pierre-Louis and Allison Parshall dive into the surprising linguistics behind the hit TV series Heated Rivalry. Pierre-Louis and Parshall speak with the show’s Russian dialect coach Kate Yablunovsky about how she helped actor Connor Storrie deliver impressively authentic Russian dialogue on a tight time line. Yablunovsky breaks down what the toughest Russian sounds are for English speakers, why perfect accents aren’t always the goal and how cultural context, mouth posture and psychology all shape believable performances.

How Heated Rivalry nailed its Russian

In this episode of Science Quickly, we dive into NASA’s latest headaches as the Artemis II moon mission hits delays. We also take a look at a massive solar flare that lit up the skies—and disrupted some tech—along with fresh concerns that PFAS “forever chemicals,” used to replace ozone‑depleting substances, are accumulating far more than expected. And new research shows that babies are actually born with a sense of rhythm.

In this episode of Science Quickly, we dig into a brewing shake-up inside psychiatry as the American Psychiatric Association considers sweeping changes to the way mental illness is defined and diagnosed. Scientific American’s associate editor Allison Parshall breaks down what the potential changes are, why long-standing diagnostic categories may no longer reflect scientific reality and what these revisions could ultimately mean for patients.

Psychiatry’s playbook is about to get torn up

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.

The curious case of the nonburpers

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.

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

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.

The hidden genius behind nonreflective glass

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.

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.
