Science Quickly

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.

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.

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.
