Henrietta Lacks’ family settle lawsuit

Henrietta Lacks was only 31 years old when she died from cervical cancer in 1951. While she was in hospital in the USA, her cells were harvested without her knowledge which, since being replicated infinitely, have gone on to enable research into cancer, dementia and Parkinson’s. As well as contributing to the development of vaccines for polio and COVID-19. Her family have fought for decades to get justice for the “stolen” cells, and this week reached a settlement with Massachusetts-based Thermo Fisher Scientific Inc. The United Nations says we now live in the era of "global boiling". As temperatures continue to soar across the southern USA, the BBC’s Health and Science Correspondent James Gallagher heads to a high-tech heated chamber in the UK, on a mission to find out how hot is too hot for our bodies to cope with. In Sweden, dentist Dr Nivetha Natarajan Gavriilidou tells Claudia Hammond about her work using the bone structure of the jaw to predict how we might get shorter as we age. Could it lead to dentists working closer with GPs? It’s a question we also put to our studio guest family doctor Ann Robinson. Who brings us new research from the USA that could lead to better treatment for children’s runny noses. And potentially some good news if you’re struggling to shave seconds off your 5KM PB. Could beating your time be down to your genes? Presenter: Claudia Hammond
