- In the not-too-distant past, between 50 - 80 million buffalo roamed Turtle Island (the name used by some indigenous peoples to refer to the continent of North America). Their natural migration patterns spread seeds, encouraged biodiversity, and kept plains ecosystems in balance. So what happened when colonizers decimated buffalo populations into the mere thousands? How are buffalo populations returning? And how is their return affecting the land today?

- Where typical ocean tides average about three feet, the Bay of Fundy’s record-setting tides soar over 50. This means 160 billion tons of water rush through the bay twice every day, generating enough potential energy to power a small city. This singular phenomenon could revolutionize our approach to renewable energy, but harnessing the Bay of Fundy’s tidal power is also extremely complicated.

- Beneath the streets of Los Angeles lies one of the most prolific fossil sites in the world. At the La Brea Tar Pits, millions of fossils including giant sloths, dire wolves, saber-toothed cats, and mammoths have surfaced from ancient asphalt, offering a rare glimpse into a vanished world.
In this episode of Human Footprint, Shane Campbell-Staton joins paleontologist Emily Lindsey to investigate the sudden disappearance of North America’s megafauna around 13,000 years ago. Together, they follow the trail of ancient life through radiocarbon dating, fossil excavations, and lake-bottom sediment cores.
For decades, scientists debated whether climate change or human hunters were to blame. But new evidence points to a more complex and unsettling cause: a dangerous combination of warming temperatures, ecological disruption, and the spread of fires… ignited by us.

- The near extinction of buffalo across North America had devastating consequences—especially for Indigenous communities, for whom buffalo were a source of food, shelter, spiritual connection, and governance. Today, Lucille Contreras, founder of the Texas Tribal Buffalo Project, is leading a powerful effort to restore buffalo to their ancestral lands in Texas. Through this work, she is also reviving cultural traditions and creating a space for her Indigenous community to reconnect with the buffalo and the way of life they represent.
The Texas Tribal Buffalo Project is one of dozens of ongoing efforts to return buffalo to their ecological and cultural place on the North American prairie. Across the continent, tribes and tribal members are raising herds that strengthen Native cultures, repair prairie ecosystems, and provide healthy local food.

- There's a strange bee called the alkali bee. And in one small valley in Washington, it's worth its weight in gold.
In Walla Walla Valley, farmers depend on alkali bees, a native species essential to one of the country’s most overlooked crops: alfalfa seed. In fact, the work of these tiny pollinators generates millions of dollars in agricultural revenue. Unlike honey bees, alkali bees take a pollen-packed smack to the face without hesitation, powering through millions of flowers with speed and precision. But alkali bees can’t be boxed, transported, or bought. They nest in the ground, require salt-crusted soil, precise irrigation, and near-perfect conditions to thrive.
In this episode of Human Footprint, Shane Campbell-Staton visits the only place on Earth where solitary, ground-nesting bees are managed for large-scale agriculture. He meets third-generation farmer Mark Wagoner and entomologist Doug Walsh, who’ve each played a role in transforming this agri...

Would you lick a 65-million-year old dinosaur poop? Granted, it’s not a question many people ask themselves - but for George Frandsen it’s a firm, “Yes!”. Not merely a dinosaur fossil hunter, George is specifically on the hunt for coprolites, the more scientific term for ancient dino dung. Already the proud owner of the world’s largest collection of dinosaur poo fossils, we join him on his quest to discover more of these rare fossils. Far from being just an amusing curiosity, coprolites can unveil a surprising amount of clues into the lives and diets of dinosaurs. As for the licking part, well that’s maybe best left for George to explain.

Could mosquitoes be the key to fighting deadly diseases?
In Medellín, Colombia, a mosquito factory breeds millions of mosquitoes every week… on purpose. Why? To stop the spread of dengue, a mosquito-borne disease infecting millions of people each year.
At the World Mosquito Program, scientists infect Aedes aegypti mosquitoes with a naturally occurring bacterium called Wolbachia, which blocks their ability to transmit viruses like dengue, Zika, yellow fever, and chikungunya. Once released, these mosquitoes breed with wild populations and spread Wolbachia, reducing disease transmission between humans.
But not everyone is convinced. Wolbachia doesn’t work the same way in every context. The effects vary by mosquito species, environment, and virus. So –while promising– this approach isn’t without its own risks. Can biocontrol out...

Millions of years ago, dinosaurs ruled the Earth. That much we all know. But underwater it was a totally different world. Marine reptiles like plesiosaurs ruled beneath the waves - to such an extent that no aquatic dinosaur has ever been discovered. But that could all be about to change. Palaeontologist Nizar Ibrahim is building a remarkable case that could upend more than a century of conventional scientific wisdom. Spinosaurus was one truly strange dinosaur, the largest predator around and with a huge sail on its back. Until now, it was thought to have lived exclusively on land. But Nizar thinks he’s found convincing fossil evidence that Spinosaurus spent a huge amount of time in the water, which would make it the first ever aquatic dinosaur.

Very few dinosaurs made it as far North as the Arctic Circle. But two of those - Pachyrhinosaurus and Edmontosaurus - undertook an epic migration every year to reach the fertile grounds of the northern latitudes in summertime. This was far from an easy task. Deadly predators lurked nearby looking to pick off weaker members of this giant herd. But thanks to one incredible fossil in particular, with its soft tissue still intact, evidence is starting to suggest that these two dinosaurs were not just coincidental travel companions. In fact, they may well have used their complementary strengths to fend off predators - and possibly even communicated with each other in order to do so.

Heat is the deadliest weather hazard in the U.S. and many places around the world, and it's only getting worse.
The most deadly heat waves so far have been dry heat waves. But a new threat is rising: humid heat waves, aka wet-bulb events. Scientists have identified wet-bulb temperatures where sweat can’t evaporate fast enough to cool the human body. And once this threshold is crossed, it doesn’t matter how much shade or water you have: you won’t survive without environmental cooling like air conditioning.
In this episode of Weathered, we break down: What wet-bulb temperature actually means, why it’s so dangerous, what areas will be affected, and why air conditioning, while essential, isn’t enough.

If all of Antarctica’s ice melted, our coastlines would be drastically altered. Fortunately, that’s not going to happen anytime soon, but new evidence suggests that West Antarctica - which holds around 5 METERS of sea level rise - is melting a lot faster than scientists once thought. And, a new study warns of a sinister threat buried deep beneath the melting ice - one that may cause a feedback loop that speeds up the melt of the already precarious West Antarctic ice sheet. Stay tuned to find out what new maps reveal about the under-ice world of Antarctica, and how a tiny octopus can help us understand the South Pole’s ice-free past.

What happens when a study goes viral? After the “trillion tree” campaign captured the internet's imagination, YouTube sensation, MrBeast, raised 20 million dollars to plant 20 million trees. But did they survive? We went to check in on them… and were shocked.
In this episode of Weathered, we get into the surprising origins of the viral “trillion tree” campaign, why it nearly ended the careers of the scientists behind it, and what actually works when it comes to storing carbon and fighting climate change. Spoiler: it’s not as simple as planting trees.

It’s one of the last remnants of the interconnected lakes that once surrounded Tenochtitlan, the ancient capital of the Aztecs. And within these canals, in a city of 22 million people, lies the last remaining wild habitat of a strange, smiling salamander called the axolotl.
