Science Podcast: Muon Magnetism, The Counting Of All Tyranosaurus Rex

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. This segment is sponsored by Oracle for Research. 

Science Podcast: Rural U.S. Sanitation Crisis, Manta Rays & Magnetic Muons

The lack of adequate sanitation in parts of the rural US, and physicists reassess muons’ magnetism.

In this episode:

00:45 How failing sanitation infrastructure is causing a US public health crisis

In the US, huge numbers of people live without access to adequate sanitation. Environmental-health advocate Catherine Coleman Flowers tells us about her new book looking at the roots and consequences of this crisis, focusing on Lowndes County, Alabama, an area inhabited largely by poor Black people, where an estimated 90% of households have failing or inadequate waste-water systems.

10:13 Reassessing muons’ magnetic moment

A decade ago, physicists measured the ‘magnetic moment’ of the subatomic muon, and found their value did not match what theory suggested. This puzzled researchers, and hinted at the existence of new physics. Now, a team has used a different method to recalculate the theoretical result and see if this discrepancy remains.
