This week, Claire finds out what we know, or more accurately don't know, about the new Omicron variant of the SARS-CoV-2 virus, with answers from epidemiologist Raina MacIntyre to some common questions about what it means for the COVID-19 pandemic; and then for a real scare, Stu introduces us to xenobots, manufactured organisms made from cells of the frogĀ Xenopus laevis, which can move about and have acquired the ability to replicate themselves.
Chris Lassig, Stuart Burns and Claire Farrugia and others.
