When in Antarctica, meeting penguins is an absolute must. But it’s not always easy. Originally published in 2020 on @pbsterra 🇦🇶 Finding — and filming — penguins was hosts Caitlin Saks and Arlo Pérez’s top priority during their month-long stay at McMurdo Station. With four species of penguin living in […]
What if Homo sapiens weren’t the only humans? Paleoanthropologist Ella Al-Shamahi joins Hakeem to explore a lost world where Homo sapiens once shared the planet with at least seven other human species. They dig into Neanderthal culture, the mysterious Denisovans, and the ancient DNA discoveries rewriting the story of who […]
If you’re a penguin or other seabird in Antarctica, there’s plenty of fish to go around. But what do the people eat? Generally, an adult human consumes around 1,600 to 3,000 calories daily. But in colder climates, people need to eat more: Keeping our warm-blooded bodies warm requires a lot […]
Here’s why centrifugal force is considered a “fictitious” force. Centrifugal force feels completely real — but physicists call it a pseudo-force. So why does it feel so powerful?

Antarctica is an otherworldly land of extremes. But perhaps nothing there is as extreme as Mount Erebus, one of Antarctica’s two active volcanoes and the southernmost active volcano on Earth. Conveniently, Erebus’ summit is a mere 25 miles from McMurdo Station, Antarctica’s largest research base. Originally published in 2020 on […]
Under the ice in Antarctica is a world few people ever get to see. Bizarre creatures—ancient sponges, gigantic jellyfish, sea spiders, ribbon worms, and notothenioid fishes that manage not to freeze—make their home here. Arlo and Caitlin learn that the Antarctic marine realm is not only spectacular to see, but […]
Daniela Rus brings robots and AI together, and as a computer scientist and roboticist at MIT, she’s here to set the record straight. She’s not just studying AI from the outside. She’s building it, and finding ways to make everyday life better. Daniela joins Hakeem to pull back the curtain […]
A simple fold can completely change how a material behaves. By changing structure instead of material, origami can transform flimsy sheets into rigid, shape-shifting systems. And scientists are still discovering entirely new ways to fold. Hosted by Athena Brensberger @astroathens 💫 📰 Stay up to date on the latest science […]
Beneath Antarctica’s glaciers, a 12-foot-long robot named Icefin explores places neither boats nor divers can reach.

The search for dark matter may be taking a surprising turn. Theoretical physicist Elba Alonso-Monsalve explains why the decades-long hunt for dark matter has led many physicists to a surprising candidate: primordial black holes. What are these mini black holes and how might they have formed? And could upcoming experiments […]
