Gene technology against tumors, artificial steak, valve transplantation

In this episode: How does the new gene therapy work, used to defeat tumors by genetically modifying immune system cells? And then: during construction work for a gas pipeline near Gambolò, in the province of Pavia, the first of a series of ancient Lombard burials was uncovered. Subsequently, 27 more were discovered and excavated. And again: a few years ago, news caused a sensation: a Dutch company had developed an artificial steak in a laboratory without the need to slaughter animals. Today, startups in the US and Europe are working on the artificial steak. Our correspondents went to take stock of the situation. Valve transplants: when a heart valve fails, it often needs to be replaced. But is it possible to have valves that last forever? We'll be following the initial results of a European project. Is there life in space?
