A Biography of Earth Across the Age of Animals Oct 28, 2025

Show notes

Thanks to a delicate interplay between plate tectonics and life, Earth’s thermostat has kept animal life thriving on our planet for half a billion years. On this week’s episode, host Samir Patel speaks with contributing writer Peter Brannen about our planetary highs and lows, and the precarious goldilocks zone our animal-filled finds itself in now. This topic was covered in a recent story for Quanta Magazine.

Each week on The Quanta Podcast, Quanta Magazine editor in chief Samir Patel speaks with the people behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math.

Audio Edition: ‘Paraparticles’ Would Be a Third Kingdom of Quantum Particle Oct 23, 2025

Show notes

A new proposal makes the case that paraparticles — a new category of quantum particle — could be created in exotic materials.

What We Learn From Running ‘Life’ in Reverse Oct 21, 2025

Show notes

Imagine a set of simple building blocks that can self-assemble into any shape you want. The possibilities for such a technology could be boundless. Inspired by nature, “complexity engineering” seeks to design such blocks, building on a classic computer simulation. On this week’s episode, host Samir Patel speaks with contributing writer George Musser about recent developments in so-called cellular automata. This topic was covered in a recent story for Quanta Magazine.

The Math of Catastrophe Oct 14, 2025

Show notes

Around 6,000 years ago, the Sahara was a lush grassland. Then, as if a switch flipped, it began to dry out, becoming the desert that we know today. Tipping points are moments in Earth’s history where gradual change suddenly becomes rapid and forms a new equilibrium.

They’re one of the most alarming threats of our planet’s near future — and one of the most uncertain.

When will a tipping point occur? Mathematicians are attempting to turn vague, apocalyptic visions into something that we can actually prepare for and deal with. On this week’s episode, host Samir Patel speaks with contributing writer Gregory Barber about what tipping points can — and cannot — tell us about the future of our planet. This topic was covered in a recent story for Quanta Magazine.

Audio Edition: Quantum Speedup Found for Huge Class of Hard Problems Oct 09, 2025

Show notes

It’s been difficult to find important questions that quantum computers can answer faster than classical machines, but a new algorithm appears to do it for some critical optimization tasks.

What Can a Cell Remember? Oct 07, 2025

Show notes

“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.

Climate Modeling Is at a Crossroads Sep 30, 2025

Show notes

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 Edition: A New, Chemical View of Ecosystems Sep 25, 2025

Show notes

Rare and powerful compounds, known as keystone molecules, can build a web of invisible interactions among species.

AI's Dark Side Is Only a Nudge Away Sep 23, 2025

Show notes

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.

How We Came To Know Earth Sep 16, 2025

Show notes

For most of us, the word “climate” immediately generates thoughts of melting ice, rising seas, wildfires and gathering storms. However, in the course of working to understand this pressing challenge, scientists have revealed so much more: A fundamental understanding of how Earth’s climate works.

Quanta recently published a nine-story series that investigates this basic science. On this episode of The Quanta Podcast, senior editor Hannah Waters joins editor in chief Samir Patel to discuss how humans have come to understand our planet.
