The Neanderthal Kama Sutra: Frictionless Materials, 3D Printing Space Rockets, and a New Neanderthal DNA Discovery

On today's episode, we dive into NASA's new RAMFIRE project to 3D print novel rocket parts. We also discuss a novel frictionless material built on the nano-level, and a new historical model that explains why Neanderthal DNA is so varied in the modern human population.
