How can we, humans, look at our relationship to nature differently? In season three of Going Wild, on top of stories about animals, we invite you to journey through the entire ecological web — from the tiniest of life forms to apex predators — alongside the scientists, activists and adventurers who study it. Wildlife biologist and host Dr. Rae Wynn-Grant has been studying wild animals in their natural habitats all over the world for years. Our award-winning podcast takes you inside the hidde ...

Flash Forward is a show about possible (and not so possible) future scenarios. What would the warranty on a sex robot look like? How would diplomacy work if we couldn’t lie? Could there ever be a fecal transplant black market? (Complicated, it wouldn’t, and yes, respectively, in case you’re curious.) Hosted and produced by award winning science journalist Rose Eveleth, each episode combines audio drama and journalism to go deep on potential tomorrows, and uncovers what those futures might re ...

DNA science. Artificial intelligence. Smartphones and 3D printers. Science and technology have transformed the world we live in. But how did we get here? It wasn’t by accident. Well, sometimes it was. It was also the result of hard work, teamwork, and competition. And incredibly surprising moments. Hosted by bestselling author Steven Johnson (“How We Got To Now”), American Innovations uses immersive scenes to tell the stories of the scientists, engineers, and ordinary people behind the great ...

We humans could have a bright future ahead of us that lasts billions of years. But we have to survive the next 200 years first. Join Josh Clark of Stuff You Should Know for a 10-episode deep dive that explores the future of humanity and finds dangers we have never encountered before lurking just ahead. And if we humans are alone in the universe, if we don't survive intelligent life dies out with us too.

Whether we wear a lab coat or haven't seen a test tube since grade school, science is shaping all of our lives. And that means we all have science stories to tell. Every year, we host dozens of live shows all over the country, featuring all kinds of storytellers - researchers, doctors, and engineers of course, but also patients, poets, comedians, cops, and more. Some of our stories are heartbreaking, others are hilarious, but they're all true and all very personal. Welcome to The Story Collider!

Basking Shark Physiology with Dr. Haley Dolton

This week we talk with Dr. Haley Dolton about how she studied the physiology of basking sharks in Ireland! This is no small feat.
We read Dr. Dolton's article, "Regional endothermic traits in planktivorous basking sharks Cetohinus maximus"
Article Summary: The majority of sharks are classified as cold-blooded or ectotherms. Sharks are constantly battling heat loss to the surrounding water. To combat this, some fast-swimming apex species are classified as regional endotherms, having uncommon physiological traits such as elevated internal body temperatures, centralized red muscle, and thick-walled hearts. Within the order Lamniformes, housing the only regionally endothermic sharks, you can find the basking shark which is a large, filter-feeding planktivorous species. Previous research has led to the conclusion that basking sharks are ectothermic. To investigate this, Dolton et al. collected muscle samples and measured the internal temperature of basking sharks finding that they displayed the traits previously stated. Their research leads to the finding that basking sharks may not be correctly classified as an ectotherm, which is a surprising find!
