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.
