Dr Chris Smith and the Naked Scientist team present the latest science news, analysis and breakthroughs.

Including the news that the US has recorded their first human death from bird flu, and should we be concerned? Plus a new drug to treat drug resistant prostate cancer, and new research on how the Roman Empire was responsible for widespread lead pollution in Europe.

In Part 2, Titans of Science returns with Marc Abrahams, the originator of the Ig Nobel Prize and the master of making science funny.

This is the final episode of 5 Live Science in this feed, but you can still hear Dr Chris Smith regularly on BBC Radio 5 Live with Naga Munchetty on a Tuesday afternoon at 1pm. You can also search for “The Naked Scientists Podcast” online for more from Dr Chris and the team.
