Before Helen Sharman replied to a rather unusual radio advertisement her life was, in many ways, quite ordinary. She was working as a chemist in a sweet factory, creating and testing flavours. Much to her surprise, her application to be an astronaut was successful and two years later, following an intense 18 month training course at a military base just outside Moscow, she was selected for Project Juno, the 1991 mission to the Soviet space station, MIR. And so became the first British astronaut. On the 25th anniversary of this historic mission, Helen talks to Jim about her life before MIR; some of the less glamorous aspects of being in space; and the difficult process of coming down to earth.

Folge vom 08.03.2016Venki Ramakrishnan on ribosomesAll the information that's needed for life is written in our DNA. But how do we get from DNA code to biological reality? That's the job of the ribosomes - those clever molecular machines that are found in every living cell. And in 2008 Venki Ramakrishnan was awarded the Nobel Prize for determining their structure. Jim talks to Venki about the frantic race to crack the structure of the ribosome, probably the most important biological molecule after DNA; why he thinks the Nobel Prize is a terrible thing for science; and his new job as President of the Royal Society.Producer: Anna Buckley.

Folge vom 01.03.2016George Davey-Smith on health inequalitiesWhen George Davey-Smith started work as an epidemiologist, he hoped to prove that the cause of coronary disease in South Wales soon after the miner's strike was Thatcherism. The miners said they thought it was a combination of having a poor constitution and bad fortune. Thirty years later, George admits he would have done well to listen to them. Having spent decades studying the influence on our health of a huge number of variables, from lifestyle factors like car ownership to our genetic inheritance and most recently epi-genetic effects; George has concluded that whether or not individuals get sick is, to a significant extent, down to chance. But that's not to say that public health interventions are a waste of time.They can boost the overall health of a population, significantly.George is director of the MRC Integrative Epidemiology Unit at the University of Bristol.

Folge vom 23.02.2016Dr Nick Lane on the origin of life on earthDr Nick Lane is attempting to answer one of the hardest questions in science. How did life on earth begin? You might think that question had been solved by Darwin in the 19th century. He wrote that he thought life might have started on earth "in a warm little pond", where all the necessary ingredients: water, sunlight and nutrients combined in this "primordial soup" to create the very first biomolecule of life. Others - like Fred Hoyle - thought that life came to earth from elsewhere in space. But Nick Lane has different ideas of how, and where, it happened. The place in question was deep under the sea in hydrothermal vents. Amongst other research he carries out at University College London, he's running an experiment to try to recreate this moment. Nick Lane had an unusual route to this point in his scientific career. For some years he left his research career to become a medical journalist and write popular books. A rare opportunity took him back into the laboratory.
