Wanna rub yourself down in hippo sweat? Well, me neither, but there is something fascinating about the aforementioned fluid: it may be synthesized and used as sunblock.

Hippos exude an oily secretion that contains light-scattering crystalline structures, and this is what keeps them from getting burned in the unrelenting African sun. Making use of nature’s knowledge in a science known as biomimicry, researchers are trying to figure out how to replicate this substance into a form appropriate for humans. Pretty amazing if you ask me. Just so long as this doesn’t implicate a future in bizarre sweaty hippo exploitation.
