Material, Heal Thyself

Episode 145 of 1055 episodes

We get Smart on this week's Naked Scientists with the science of self-healing, self-sensing and self-cleaning materials. We hear how carbon fibre polymers could lead to self-healing spacecraft, why a titanium coating keeps windows clean and kills superbugs, and how helicopters can warn you when they're damaged. Also, how gut bugs tell the story of our ancestors' migration into Australia and beyond, how RNA housekeeping allows humans to function with fewer genes than a banana, and how molecular metal cages safely store hydrogen, or sieve out carbon dioxide. Plus, we mix borax and glue to make bouncy, stretchy goo!
