    Lightning makes new isotopes

    A streak of lightning in the skies over Japan has generated positrons – the antimatter equivalents of electrons – and radioactive carbon-14, confirming a theoretical prediction, according to a paper published in Nature on 22 November.


    The main source of the carbon-14 in the atmosphere has generally been considered to be cosmic rays.

    In principle, lightning could also contribute to the supply.
