Join us on a time traveling adventure, as we go back 15,000 years to visit what’s now southern California. During the last Ice Age, saber-toothed cats, wooly mammoths, and dire wolves prowled the landscape, until … they didn’t. The end of the Ice Age coincided with the end of these species. And for decades, scientists have been trying to figure out a big question: Why did these animals go extinct?
A new study in the journal Science offers new clues and suggests that wildfires caused by humans might’ve been the nail in these critters’ coffins.
Guest host Flora Lichtman talks with paleoecologist Dr. Emily Lindsey and paleobotanist Dr. Regan Dunn, both curators at the La Brea Tar Pits and Museum in Los Angeles, California, about what we can learn from animals preserved in tar pits, how fire transformed the ecosystem, and why we have to look to the past for modern day conservation and land management.
How Scientifically Accurate Are The Sharks In ‘Meg 2: The Trench’?
“Meg 2: The Trench” is the sequel to the 2018 movie “The Meg,” in which a team of ocean scientists discover a megalodon, the largest shark that ever lived, thriving at the bottom of the Mariana Trench. Megalodon went extinct over 2.6 million years ago … or so the movie’s characters thought.
When the team’s research sub gets damaged, a skilled rescue diver, played by Jason Statham, is brought in, who happened to have encountered the same megalodon years earlier. Over the course of the movie, the team discovers how this long-thought extinct apex predator survived, and what they can do to stop it before it wreaks havoc on the surface world.
“Meg 2: The Trench” largely follows in that movie’s footsteps, but this time, it features not just one, but multiple megalodons. Oh, and they’re even bigger this time.
Universe of Art host D. Peterschmidt chats with Dr. Sora Kim, an associate professor of paleoecology at University of California, Merced, about what science the movie got wrong (and right) and how these over-the-top blockbusters can inspire the scientists of the future.
Scientists Discover Dinosaur ‘Coliseum’ In Alaska’s Denali National Park
Researchers recently discovered a rocky outcrop at Denali National Park in Alaska covered in dinosaur tracks, which they dubbed the “Coliseum.” It’s the largest dinosaur track site ever found in Alaska.
The area has thousands of prints from generations of dinosaurs living about 70 million years ago, including: duck-billed dinosaurs, horned dinosaurs, raptors, tyrannosaurs.
Flora Lichtman talks with Dustin Stewart, former graduate student at the University of Alaska Fairbanks and paleontologist for the environmental consulting firm Stantec, based in Denver, Colorado, about this dino hotspot.
Your Guide To Conquering History’s Greatest Catastrophes
Guest host Flora Lichtman takes us back to some of the scariest, deadliest moments in history. Think along the lines of the eruption of Mount Vesuvius, the Ice Age, and the asteroid that wiped out the dinos. But we’re going to revisit them using what we know now—and science, of course—to figure out if and how we could survive those events.
The idea of using science and hindsight to survive history is the premise of a new book, How to Survive History: How to Outrun a Tyrannosaurus, Escape Pompeii, Get Off the Titanic, and Survive the Rest of History’s Deadliest Catastrophes by Cody Cassidy.
We have a new podcast! It’s called Universe Of Art, and it’s all about artists who use science to bring their creations to the next level. Listen on Apple Podcasts, Spotify, or wherever you get your podcasts.
