By reconstructing a nearly forgotten 1938 experiment, scientists have uncovered new significance in an early observation of deuterium-tritium fusion that still shapes nuclear science today. (Artist’s concept). Credit: SciTechDaily.com Physicists confirm DT fusion insights from a 1938 experiment. The findings connect past theory with current fusion efforts. A team at Los Alamos National Laboratory has successfully recreated a significant yet largely overlooked physics experiment: the first recorded observation of deuterium-tritium (DT) fusion. Their updated version of the 1938 experiment, recently detailed in Physical Review C, reaffirms the pivotal role of University of Michigan physicist Arthur Ruhlig. Ruhlig’s original work likely...

Manchester is hosting a series of events to mark the centenary of a paper by Ernest Rutherford that changed the way we looked at the world and Universe around us.In 1911, Rutherford, described as the father of nuclear physics, presented his research to the Manchester Literary and Philosophical Society, which - for the first time - described a "planetary structure" of atoms, one that we still recognise today. "Before Rutherford, people had thought about atoms as an amorphous lump, the "plum pudding model" we sometimes hear about," explained Catherine Rushmore, science curator at the Museum of Science and Industry (Mosi)....
