0:46 Borrowing tricks from cancer could help improve immunotherapy

T cell based immunotherapies have revolutionised the treatment of certain types of cancer. However these therapies — which involved taking someone’s own T cells and reprogramming them to kill cancer cells — have struggled to treat solid tumours, which put up multiple defences. To overcome these, a team has taken mutations found in cancer cells that help them thrive and put them into therapeutic T cells. Their results show these powered-up cells are more efficient at targeting solid tumours, but don’t turn cancerous themselves.

14:28 What might the car batteries of the future look like?

As electric cars become ever more popular around the world, manufacturers are looking to improve the batteries that power them. While conventional lithium-ion batteries have dominated the electric vehicle market for decades, researchers are developing alternatives that have better performance and safety — we run though some of these options and discuss their pros and cons.
