What Can a Cell Remember?
“Memory” means many things to many people, and in many fields. We tend to understand memory to be a phenomenon that happens primarily in the brain, but in recent years, researchers have understood memory as a physical phenomenon that can occur in plenty of systems. On this episode, contributing writer Claire L. Evans tells host Samir Patel about how neuroscientists are probing the memory of individual cells.Audio coda courtesy of YACHT.

Climate Modeling Is at a Crossroads
The climate is changing. So is the way we understand the climate. On this week's episode, contributing writer Zack Savitsky joins host Samir Patel to discuss his recent reporting on the rich history and uncertain future of climate modeling, the field of science that blends math, physics, and earth science to predict the behavior of our planet's complex climate system.Audio coda courtesy of Princeton University

AI's Dark Side Is Only a Nudge Away
In order to trust machines with important jobs, we need a high level of confidence that they share our values and goals. Recent work shows that this “alignment” can be brittle, superficial, even unstable. In one study, a few training adjustments led a popular chatbot to recommend murder. On this episode, contributing writer Stephen Ornes tells host Samir Patel about what this research reveals.Audio coda from The National Archives and Records Administration.
Exploring the distant universe, the insides of cells, the abstractions of math, the complexity of information itself, and much more, The Quanta Podcast is a tour of the frontier between the known and the unknown. In each episode, Quanta Magazine Editor-in-Chief Samir Patel speaks with the minds behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math. Quanta specifically covers fundamental research — driven by curiosity, discovery and the overwhelming desire to know why and how. Join us every Tuesday for a stimulating conversation about the biggest ideas and the tiniest details.(If you've been a fan of the Quanta Science Podcast, it will continue here. You'll see those episodes marked as audio edition episodes every two weeks.)
