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.
As cities continue to grow, scientists are trying to define the “Urban Equation” – a mathematical expression that defines not just a group of buildings, but a complex network of physical and social interactions. Why? Because our cities control previously elusive aspects of human evolution. To understand our cities is to understand us. In this episode, Luis Bettencourt and Tyler Nordgren discuss various elements of the urban equation. We see how complex networks give rise to creativity; how to break an urban metropolis down into a series of mathematical symbols; and how our cities are dramatically affecting a cultural connection reaching back nearly 400 years.

As we kick off this new season of Generation Anthropocene, I thought that I’d take some time to answer some of the most queried questions on Google about geologists. Specifically, I tackled the question, “Are geologists…” followed by every letter of the alphabet and the resulting autofill question. Unsurprisingly, some of the letters hadn’t been searched enough for autofill to work. And yet, some letters yielded some of the strangest questions I’ve ever heard about geologists. Without further ado, here are my attempts at answers: Continue reading
After 30 years in high-tech marketing and general management, Anne Sanquini began a second career as a researcher studying how to motivate people to take precautionary action to protect their homes and school against earthquakes. Her work over the past four years led her to Kathmandu Valley in Nepal. She was on the ground during the April 25 earthquake, the very quake she had been preparing for.
