Why muon magnetism matters, and a count of all the Tyrannosaurus rex that ever lived

Host Sarah Crespi talks with Staff Writer Adrian Cho about a new measurement of the magnetism of the muon—an unstable cousin of the electron. This latest measurement and an earlier one both differ from predictions based on the standard model of particle physics. The increased certainty that there is a muon magnetism mismatch could be a field day for theoretical physicists looking to add new particles or forces to the standard model.   Also on this week’s show, Charles Marshall, director of the University of California Museum of Paleontology and professor of integrative biology, joins Sarah to talk about his team’s calculation for the total number of Tyrannosaurus rex that ever lived. In a sponsored segment from the Science/AAAS Custom Publishing Office, Sean Sanders interviews Imre Berger, professor of biochemistry at the University of Bristol, about his Science paper on finding a druggable pocket on the spike protein of SARS-CoV-2 and how the work was accelerated by intensive cloud computing.
