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 coda courtesy of Martin Rietze's YouTube channel.

A new proposal makes the case that paraparticles — a new category of quantum particle — could be created in exotic materials.The story ‘Paraparticles’ Would Be a Third Kingdom of Quantum Particle first appeared on Quanta Magazine.

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.

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.

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.The story Quantum Speedup Found for Huge Class of Hard Problems first appeared on Quanta Magazine.

“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.

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

Rare and powerful compounds, known as keystone molecules, can build a web of invisible interactions among species.The story A New, Chemical View of Ecosystems first appeared on Quanta Magazine.

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.

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.Crying Glacier Audio Coda by Ludwig Berger, Lutz Stautner and Philipp Becker

The deceptively simple Kakeya conjecture has bedeviled mathematicians for 50 years. A new proof of the conjecture in three dimensions illuminates a whole crop of related problems.The story ‘Once in a Century’ Proof Settles Math’s Kakeya Conjecture first appeared on Quanta Magazine.

In the field of harmonic analysis, there’s a constellation of questions about how the energy of a wave concentrates.Earlier this year, a 17-year-old high school student named Hannah Cairo solved a 40-year-old mystery about how some of these waves behave, surprising and exciting mathematicians. Cairo has not yet obtained a high school or undergraduate degree, but she recently began a doctoral program at the University of Maryland to continue her already impressive career studying mathematics. In this week's episode, math editor Jordana Cepelewicz joins host Samir Patel to discuss the significance of Cairo's proof.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.

In science textbooks, Earth looks like a round layer cake. There's a hard line between the liquid metal core and the putty-like rock mantle. But maybe that boundary is a little fuzzier than we previously thought. Strange, continent sized blobs rest on the dividing line. These blobs are leaching material from the Earth’s core, extending arms out into the mantle, and sending core material up and out through magmatic plumes. No one's completely sure how it’s happening. On this week’s episode, host Samir Patel and writer Robin George Andrews dig into the ancient isotopic signatures that are helping us better understand the material bubbling up from the depths of our planet.

Astronomers are ready to search for the fingerprints of life in faraway planetary atmospheres. But first, they need to know where to look — and that means figuring out which planets are likely to have atmospheres in the first place.The story How Undergraduate The Road Map to Alien Life Passes Through the ‘Cosmic Shoreline’ first appeared on Quanta Magazine.

We’re living in the golden age of cryptography. Since the 1970s, we've had more confidence in encryption than ever before. But there's a difference between confidence and absolute certainty. And computer scientists care a lot about that difference.The search is always on for better, more secure secrets. But is it possible for digital security to be truly, provably unbreakable? Maybe, with a little help from math and physics. On this week’s episode, host Samir Patel talks with 𝘘𝘶𝘢𝘯𝘵𝘢 computer science staff writer Ben Brubaker about a developing frontier of digital security: quantum cryptography.
