Scientists are always searching for new materials that maximize strength and thermal protection while also minimizing mass for space flight. So, when developing new heat shields, why are they looking to cuttlefish for inspiration? Hosted by: Caitlin Hofmeister SciShow has a spinoff podcast! It's called SciShow Tangents.
