Invertebrates. Gutless, spineless– but perhaps underappreciated invertebrates. We probably don’t spend enough time thinking about that other category of organisms on earth, so on this episode we’re going to spend some time with maybe the most overlooked group of Eukaryotes: Fungi. As it turns out, there are (at least) five MIND BLOWING facts about fungi that we all need to know. We’ll then travel to Southeastern Alaska to study the changing forest community. A wave of climate-driven ecological change is sweeping across the region, and we’ll learn about what this means for forests and the people who live there. Finally on today’s show we leave the invertebrates and debut a new segment that we’re calling Convos with Kau (as in coversation with Kaustubh Thirmulai, PhD candidate in paleoclimate at UT-Austin).
This week, we explore communication: how do we talk? how do we hear? and what the hell are we even saying? And what about the rest of the animal kingdoms? African elephants don’t just communicate through trumpeting – they also use seismic waves. Elephant behavior expert Caitlin O’Connell explains this “second language,” and how it’s helping advance hearing aid technology. She also tells us about her new work of fiction, Ivory Ghosts, which draws attention to the intensifying problem of illegal ivory trade. We then talk to evolutionary biologist Nicole Creanza, who explains that we can learn a lot about early human migration across the globe not just through genetics, but also through our languages.

Most of the epic survival stories you’ve read probably involve crazy mountain climbers, adventurous cave divers, or bearded and grizzled desert hikers. Scientists aren’t typically mentioned in this company. But sometimes, geologists find themselves enduring nature’s worst in the pursuit of that must-have dataset… or at least, a dataset that seemed really important at the time. Here are three stories about four geologists who found themselves at the wrong place at the wrong time when nature removed her flowery veil and donned her murder hat. But before I get into those, it needs to be said that people perished during the events of some of these stories. Given that, please consider this a celebration of the perseverance, luck, good fortune, and bad-assery of those who survived. Continue reading
Science is constantly reinventing itself, revising past theories and proposing new ideas that hopefully further our understanding of the world. Copernicus proposed the heliocentric solar system, Newton had gravity, and Einstein gave us relativity. But every once in a while, a theory gets proposed that’s downright nutty. Not only that, some of these theories can persist for decades or even centuries. As these ridiculous theories hang around, sometimes they find themselves intersecting with strange moments in history. Here, I present the crazy history you’ve never heard of behind 3 ridiculous geological theories. Continue reading
