Last week, astronaut James Lovell died at the age of 97. In April of 1970, he was the commander of the Apollo 13 mission, which launched with three astronauts en route to the moon. While in space, however, the craft encountered a serious problem: an explosion in one of its fuel tanks that severely damaged the craft and disabled its electrical system, prompting the famous phrase, “Houston, we've had a problem.” In 1995, on the occasion of the 25th anniversary of the mission, Host Ira Flatow spoke with Lovell about the historic flight and how good luck and ingenuity among the crew and mission controllers on the ground combined to bring the Apollo 13 astronauts safely back to Earth.Guest:James Lovell was a NASA astronaut and commander of the Apollo 13 mission.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Paleontologists have identified an ancient reptile with a towering crest made not of skin, or scales, or feathers, or antler—but something else entirely. It's some kind of integumentary outerwear we've never seen before. The small creature sporting the curious crest was named Mirasaura grauvogeli, and it lived during the Middle Triassic period, about 247 million years ago, just before dinosaurs evolved. Host Flora Lichtman talks to evolutionary biologist Richard Prum about this dramatic dorsal mystery and what it tells us about the evolution of dinosaurs, birds, and feathers. Plus, how fast did dinosaurs run? It turns out that the equation scientists have been using for five decades to estimate dinosaur speeds is not completely accurate. To understand what this could mean for velociraptor velocities, T. rex tempos, and spinosaurus speeds, Flora talks with paleobiologist Peter Falkingham.Guests: Dr. Richard Prum is a professor of ecology and evolutionary biology and head curator of ornithology at the Peabody Museum of Natural History at Yale University in New Haven, Connecticut.

Australia is known for its unusual animal life, from koalas to kangaroos.

They're all extinct now, and researchers are trying to figure out why.

While there are a lot of dinosaur fossils, and a lot of plant fossils, the precise connection between the two has been something of a mystery. Now, researchers report that they've found what's called a cololite, fossilized gut contents, in the remains of a sauropod—a massive, long-necked plant-eater. The dino's last meal dates back 95 to 100 million years. Paleontologist Stephen Poropat joins Host Flora Lichtman to dig into the mysteries of a dinosaur's tummy.And, for prairie dogs, communication is key. The rodents' yips and barks can warn when danger is near—and not just to other prairie dogs. A new study suggests that birds called long-billed curlews are eavesdropping on this chatter to learn when a predator is lurking nearby. Using speakers and a taxidermied badger on wheels, ornithologists are untangling the social dynamics of black-tailed prairie dogs.
