The Life Scientific Folgen

As the Curiosity rover ventures into previously unexplored territory on the surface of Mars and attempts to pick up and analyse rock samples for the first time, many hope that the NASA robot might find signs of life on the red planet. But, after so many false dawns and with such ambiguous evidence, how can we know for certain whether or not there was ever life on Mars? Jim al-Khalili and Monica Grady, Professor in Planetary Sciences at the Open University, discuss what life on Mars might look like; Monica's passion for meteorites and the asteroid named "monicagrady" in her honour.

Professor Hugh Montgomery is an intensive care physician and researcher at University College Hospital in London. His work has taken him to the Himalayas, where he and colleagues were studying the effect of oxygen uptake at high altitude. The findings were surprising and have implications for patients in intensive care. Jim al-Khalili talks to Hugh Montgomery about the gene for fitness and how mountaineers have influenced intensive care medicine.

Jim al-Khalili talks to the next chief scientific advisor to the government, Sir Mark Walport about how he thinks science can save the UK economy; how he plans to ensure that scientific evidence is taken seriously by an arts-dominated civil service and why he believes scientific research should be made available to everyone, free of charge. Sir Mark, who started his Life Scientific studying immune responses, has spent the last ten years in charge of one of the largest funders of medical research in the world, the Wellcome Trust. Many love his robust, straight-talking style: others find him uncompromising. He hopes to tackle environmental change and many of the problems associated with our ageing population, as well as changing Whitehall's attitude to science. It's hard to predict what other issues he may have to deal with, but even without an unexpected crisis, many anticipate that his forthcoming time in government will be nothing if not eventful.
