We’ve grown used to hearing about potential new treatments for Covid-19 – well here’s another. Researchers in Britain have, by chance, discovered that a tablet used to treat liver disease for decades could be repurposed to stop Covid-19 in its tracks.

The drug appears to shut a crucial ‘doorway’ the virus uses to get into our cells – and scientists are excited about its potential to tackle different variants and provide a low-cost weapon in the pandemic. We hear how researchers used a combination of ‘mini organs’, animals and humans to show how it could work – and what needs to happen next to confirm the findings.

And Claudia Hammond’s guest this week is Dr Graham Easton, a family doctor and professor of clinical communication skills at Queen Mary University of London. He delves into new research that suggests short bursts of vigorous activity could reduce risk of death and finds out which Olympic sports are most likely to cause injuries. Spoiler: It’s not the more traditional ones…
