Diatoms are tiny, unicellular creatures, inhabiting oceans, lakes, rivers, and soils. Through their respiration, they produce close to a quarter of the oxygen on Earth, nearly as much as the world's tropical forests. In addition to their ecological success across the planet, they have a number of remarkable properties.
