When the human genome was sequenced, scientists promised a plethora of cures and treatments for some of the world's most pernicious diseases. But what's really happening today? Hear UCL's Simon Waddington explain about the latest goings-on in the field of gene therapy (and see the British Society of Gene Therapy website for more).
Where are we right now? What will future developments look like? What do you think will happen?
We also hear from Craig Venter, founder of the Venter Institute and the "bad boy of science", talking about his latest audacious project - to map the ocean's DNA. Is he going to make a significant contribution to scientific knowledge? Or is he just a master showman?
Plus we have a special appearance from none other than Tony Blair, who takes some time out of his busy schedule to sit back, relax, and tell us what he thinks of Science Weekly.
