Episodes
What does it feel like to make one of the biggest discoveries in physics? Adam Riess knows — because his work revealed that the universe isn’t just expanding, it’s accelerating. In this episode, the Nobel Prize–winning astrophysicist takes us behind the scenes of the moment that changed cosmology forever. How did his team use exploding stars as “standard candles” to measure the cosmos? Why did the data point to a mysteriou...
The universe isn’t adding up—and it’s creating a crisis in cosmology. Nobel Prize winner Adam Riess explains why measurements of the universe’s expansion rate from its earliest light and from nearby galaxies don’t match, and how this growing gap threatens the foundations of our standard model of the cosmos.

...Discovering dark energy wasn’t just thrilling—it was terrifying. Nobel Prize Winner Adam Riess explains the nerve-wracking process behind confirming that the universe’s expansion is accelerating and why Einstein’s so-called “biggest blunder” turned out to be anything but.

Fame can hijack the brain like a drug—activating the same reward circuits that fuel a relentless chase for dopamine highs. Neuroscientist Heather Berlin reveals the antidote—and why even social media fame can trigger this cycle.

Fossilization isn’t luck - it’s geology. Paleobotanist Kirk Johnson explains how fossils only form in certain conditions, the tricks to finding them, and why one fossil leaf can lead to thousands more.

How does evolution invent entirely new things, like limbs, wings, and venom? Evolutionary biologist Sean B. Carroll joins us to reveal the hidden rules behind nature’s creativity and the genetic toolkit that makes it possible. Carroll explains how the same set of genes can build wildly different creatures — from fruit flies to lobsters — simply by rewiring their genetic circuits. Discover why developmental biology holds th...
From legs on heads to missing eyes, fruit fly mutations exposed the genetic toolkit that builds all animals. Evolutionary Biologist Sean B. Carroll shows how these discoveries rewrote our understanding of evolution.

The edge of a black hole isn’t what you think. Astrophysicist Janna Levin dives into the event horizon, the one-way transition where space and time warp so much that escape becomes as impossible as reversing the clock.

There’s no single ‘smoking gun’ for life beyond Earth. Microbiologist Peter Girguis explains the subtle fingerprints scientists hunt for—and why finding them on Mars could change everything.

Can we bring extinct species back to life? Evolutionary biologist Beth Shapiro claims we just did. As Chief Science Officer at Colossal, her team made headlines in spring 2025 with the announcement of the de-extinction of the dire wolf. She takes us behind the headlines to explain how this is no “Jurassic Park” fantasy. She breaks down exactly how her team used ancient DNA, CRISPR genome editing, and the genomes of modern ...
Jurassic Park got it all wrong. Beth Shapiro would know… she’s Chief Science Officer at Colossal, the genetic engineering company that recently made headlines for bringing back the extinct dire wolf. She breaks down how de-extinction is really done, and why Jurassic Park can never happen.

The deepfake game is getting real. Deepfake detective Hany Farid gets under the hood of AI and explains exactly how it can now make such convincing fake content – so convincing that he himself has trouble identifying his own real voice from an AI-generated fraud. Can you spot the deepfake?

Space itself rings with gravitational waves when black holes collide—the most powerful events detected since the Big Bang. Astrophysicist Janna Levin reveals why, when the cosmic symphony fades, the merged black hole is stripped to flawless simplicity.

Could a Martian rock hold the most promising sign of life beyond Earth? Microbiologist Peter Girguis unpacks NASA’s stunning discovery of ‘leopard spots’ on a rock from Mars’s Jezero Crater—and why they look eerily like the handiwork of microbes on our own planet.

A sinkhole can become a time capsule full of skeletons - layers upon layers of beasts that once walked the Earth - and Florida’s landscape is full of them. Discover the surprising science of how Florida’s sinkholes form, what they really are, and what can be found inside them. Come along with Dr. Kirk Johnson, Sant Director of the Smithsonian Institution National Museum of Natural History, as he describes what he calls "th...
In a world flooded with fake videos and voice recordings that seem real, how can you detect deepfakes? Turns out, there are some aspects of the physical world that are not yet known to artificial intelligence - and those gaps are the key. Expert Hany Farid reveals techniques that can be used to detect AI-generated media.
