Nuclear bomb tests reveal brain regeneration in humans

Nuclear bomb tests reveal brain regeneration in humans - health - 07 June 2013 - New Scientist: "Nuclear bomb tests carried out during the cold war have had an unexpected benefit. A radioactive carbon isotope expelled by the blasts has been used to date the age of adult human brain cells, providing the first definitive evidence that we generate new brain cells throughout our lives. The study also provides the first model of the dynamics of the process, showing that the regeneration of neurons does not drop off with age as sharply as expected."
