You might know it as a drink for hipsters or as an ancient brew drunk for centuries in Eurasia, but the culture that ferments sugary tea into Kombucha is going around the world. Bolted to the outside of the International Space Station are the same bacteria and yeasts that are used in making Kombucha.

Hydrogen peroxide -- commonly used as hair bleach -- may have provided the energy source for the development of life on Earth, two applied mathematicians have found.
