FRAGMENT FROM NATURE focuses on a very thoughtful article on astrobiology by the computational physicist, Dr Dimitri Atri. The article is entitled ‘On the possibility of galactic cosmic ray-induced radiolysis-powered life in subsurface environments in the Universe.’ It is often said that 21st century biology is where physics was in the 19th century; contributing to this is the fact that current biology has two monumental failings: (1) no acceptable explanation for the origin of life, and (2) no consensus definition for what life is. This excellent article tackles a part of the first open question.
