How the Earth adapted to life has much to do with the generation of a stable oxygen atmosphere. But how life adapted to Earth often hinges on whether oxygen is a poison. New research on insect oxygen use highlights the novel ways that life has shaped the Earth, and vice versa.


Word of the Day
postliminy
  • In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
  • In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
The word 'postliminy' comes from a Latin word meaning 'threshold'.
