The Life Scientific Folgen

Jim Al-Khalili talks to the former technical director of British Nuclear Fuels, Dame Sue Ion, about a lifetime of working in the nuclear industry. When Sue got her first job at a nuclear fuel fabrication plant in Preston, nuclear power was generally seen as force for good but, during the dark decades post Chernobyl, it was a hard sell. Still, Sue continued to push for investment and innovation in the industry and in 2006 persuaded Tony Blair to change his mind about nuclear power, insisting that if Britain is to have any chance at all of keeping the lights on and cutting its carbon emissions, we will need to invest heavily not only in renewables like offshore wind but also in a new generation of nuclear power stations.

Jim Al-Khalili talks to Professor Alan Watson from the University of Leeds who has spent 40 years trying to unravel a mystery at the frontier of physics. Where do cosmic rays, subatomic particles with the highest known energies in the entire Universe, come from? And which violent astronomical events are producing these hugely energetic jets of particles that travel for light years to reach us? As many as a million of them pass through us every night as we sleep, the equivalent of having 2 chest x rays every year. His quest to find the origins of cosmic rays has taken him from the North York Moors to the South Pole and the pampas grasslands of Argentina where he has been instrumental in creating the largest ever Cosmic ray detector, covering an area bigger than Luxembourg.

Jim Al-Khalili talks to breast cancer pioneer, Professor Valerie Beral director of the cancer epidemiology unit in Oxford about her Million Women study and why she thinks a so-called 'vaccine' should be developed to prevent breast cancer. Jim finds out why the brilliant mathematician who became female Australia junior chess champion as a teenager and who got a first class degree in medicine decided she was unhappy with the uncertainties of diagnosis as a doctor, and turned her back on clinical medicine in the quest for answers to the bigger questions about public health. She talks about pioneering research into the causes of cancer, effects of the contraceptive pill, radiation from Chernobyl and Hiroshima. Most recently as lead investigator on the million women study she has looked at the risks and health effects from taking HRT. She has said that it is a 'crime' that more research hasn't been done on what is known about women who don't get breast cancer to prevent breast cancer in other women.
