00:47 Chemical analysis of ancient embalming materials

Mummification was a significant part of ancient Egyptian culture but, despite decades of research, much is unknown about the substances and methods used during the process. Now a team have analysed the contents of ceramic vessels uncovered in an embalming workshop that dates back to around 600 BC. The results reveal that some substances assumed to be a single thing were actually mixtures, while some came from far outside Egypt, providing a clearer picture of ancient mummification practices.

11:28 The race to refine CAR-T therapies

CAR-T therapies are a type of cancer immunotherapy in which part of a person’s immune system – their T cells – are engineered to recognise and attack tumours. While these therapies have been shown to be effective at treating certain blood cancers, they are expensive and can have serious side effects. We hear about efforts to tackle these issues and even expand the range of diseases that CAR-T could be used to treat.
