Gamma radiation can convert methane into a
wide variety of products at room temperature,
including hydrocarbons, oxygen-containing
molecules, and amino acids, reports a
research team in the journal Angewandte
Chemie. This type of reaction probably
plays an important role in the formation
of complex organic molecules in the
universe -- and possibly in the origin
of life.
