New technology solves mystery of respiration in Tetrahymena

Tetrahymena, a tiny single celled-organism, turns out to be hiding a surprising secret: it's doing respiration—using oxygen to generate cellular energy—differently from other organisms such as plants, animals or yeasts. The discovery, published March 31 in Science, highlights the power of new techniques in structural biology and reveals gaps in our knowledge of a major branch of the tree of life.
