How radiotherapy kills cancer cells
Dr Jason Greenwood from Queen’s Centre for Plasma Physics collaborated with academics from Italy and Spain on the work on electrons, which has been published in the international journal Science. Using some of the shortest laser pulses in the world, the researchers used strobe lighting to track the ultra-fast movement of the electrons within a nanometer-sized molecule of amino acid. The resulting oscillations — lasting for 4,300 attoseconds (billion-billionths of a second) — amount to the fastest process ever observed in a biological structure. …
