Should we be scared of AI viruses?

The extreme possibilities of synthetic biology hit the headlines last week, when researchers at Stanford University in the US announced they had created new kinds of viruses designed by Artificial Intelligence. Roland Pease is joined by microbiologist Dr Simon Clarke from Reading University and Joy Zhang, Professor of Sociology at the University of Kent, to discuss whether we should be concerned about the prospect of AI viruses. Meanwhile, 50 years ago NASA's remarkable Viking space probes touched down on Mars, breaking new frontiers in space science. Claire Cousins, part of the European Space Agency's team working on the ExoMars Rover, joins us to take a look at how today’s ambitious projects built on their success. And science and technology journalist Gareth Mitchell joins us to discuss the week’s science news.
