The Life Scientific Folgen

Carol Black was an overweight child who, aged 13, put herself on a diet. Now, as an expert advisor to the government, she's the woman behind recent newspaper headlines suggesting that obese people who refuse treatment could see their benefits cut. In the last decade, Carol has conducted several reviews on work and health, sickness absence and how best to help people with obesity, alcohol and drug problems get back into the workplace. In 2008 she suggested the Sick Note should be replaced with a Fit Note which states what people can do rather than what they can't. Later she recommended that an independent assessor should decide who is, or is not, Fit for Work. Dame Carol Black talks to Jim Al-Khalili about the challenges associated with advising government on these controversial issues; and how, despite relative adversity and several bad decisions, she achieved such a position of power and influence.Producer: Anna Buckley.

Jim al-Khalili talks to botanist Geoff Palmer, the UK's only professor of brewing and distilling, about revolutionising the malting industry and his unusual scientific career after arriving from Jamaica in 1955 as a 14 year old boy. When he went for an interview for an MSc in 1964 the representative from the Ministry of Agriculture suggested he go back home and grow bananas. Why? Because he didn't know the difference between wheat and barley. Undeterred he went on to become a world authority on barley, brewing and distilling and Scotland's first black professor. His research on how malt could be made more quickly saved the brewing industry millions. But he says, it's only through good luck and with the help of good Samaritans that his career took the course it did, helping him get to university and even to finish school. Now at the age of 75, he's still fighting to make education and a scientific career available to everyone, regardless of their background.

EO Wilson has been described as the "world's most evolved biologist" and even as "the heir to Darwin". He's a passionate naturalist and an absolute world authority on ants. Over his long career he's described 450 new species of ants. Known to many as the founding father of socio-biology, EO Wilson is a big hitter in the world of evolutionary theory. But, recently he's criticised what's popularly known as The Selfish Gene theory of evolution that he once worked so hard to promote (and that now underpins the mainstream view on evolution). A twice Pulitzer prize winning author of more than 20 books, he's also an extremely active campaigner for the preservation of the planet's bio-diversity: he says, "destroying rainforest for economic gain is like burning a Renaissance painting to cook a meal".EO Wilson talks to Jim al-Khalili about his life scientific.
