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.

The BBC’s Anna Holligan reports from the cycle-friendly Netherlands on an innovative new bike donation scheme that is being used to break down barriers and improve mental health for refugees and in deprived communities.
