episode Full Interview: Dark Matter = Black Holes? cover

Description

David Kaiser thinks the dark matter puzzle is getting closer to being solved.  Nearly a century of observations, from galaxy clusters to the cosmic microwave background, have built a compelling case for dark matter's existence, but in recent years, the leading candidates for this mysterious matter have been coming up short..  Enter black holes. Tiny ones. David explains how so-called primordial black holes that formed in the first moments after the Big Bang could possibly be all our dark matter… if they exist at all. Fortunately, this is a testable theory, and David explains the exciting new experiments that could potentially lay this cosmic mystery to rest.  Make sure to subscribe now so you never miss an episode.

Full Interview: Anxiety Hacking

Wendy Suzuki hopes you have anxiety—good anxiety. She thinks that feeling you try to avoid could actually be your edge! Wendy joins Hakeem to explore how anxiety can be harnessed, rather than eliminated, and how it connects to two other powerful forces shaping your brain: exercise and human connection. What’s happening in that surge of stress—or in the “neurochemical bubble bath” after a hard run? Can you really train your brain to use it differently? And what do oxytocin, prairie voles, and decades of research reveal about why social bonds may be the most powerful force shaping our health, happiness, and longevity.  Make sure to subscribe now so you never miss an episode.

Full Interview: T. rex to Birds

Steve Brusatte has the dirt on dinosaurs and joins Hakeem to trace the full 100-million-year history of the tyrannosaur dynasty, the asteroid that ended it, and the remarkable truth that dinosaurs never actually disappeared. One small lineage survived to become every bird alive today, and Steve walks through the long and contested scientific history of how we came to understand that connection. He also shares what it was like to serve as the official paleontology consultant on the Jurassic World films, and how to find the balance between science and cinema.
