The Life Scientific Folgen

Long before most of us gave air pollution a second thought, Frank Kelly was studying the impact of toxic particles on our lungs. In a pioneering set of experiments on human volunteers in northern Sweden, he proved that pollutants, such as nitrogen oxides and particulates, are harmful to our health. And he is the driving force behind an air quality monitoring system in London that is the envy of the world. When in the late 1990s, the UK government was encouraging us all to buy diesel cars to help reduce our carbon emissions, he warned that while diesel engines might be less bad for the planet than petrol engines, they were more damaging to our health. Later Frank and his team provided evidence that the car manufacturers were not telling the truth about emissions from diesel vehicles. As the chair of the Government Medical Committee on the Medical Effects of Air Pollution, he has worked tirelessly to try and move air pollution up the political agenda and worked closely with successive Mayors of London to improve air quality in the capital. Changing all the buses from diesel to hybrid or electric vehicles would make a huge difference, he says. But we will also need to get used to relying less on driving our cars to get us from A to B.

Professor Debbie Pain has spent the last 30 years solving some of the most devastating threats to birdlife, saving many species from the brink of extinction. Her childhood passion for bird spotting drove her into conservation research with the RSPB and the Wildfowl and Wetlands Trust. She’s led scientific groundwork all over the planet: from reversing a dramatic mysterious decline in Asian vultures in the Indian sub-continent through to daring helicopters journeys into remote foggy North-East Russia in a bid to locate and conserve eggs of a hugely charismatic and threatened bird - the Spoon-billed Sandpiper. And as she tells Jim, her career defining research into one of the great hidden threats to birdlife - the toxic effect of billions of spent lead shot used to catch game birds - is finally turning the tide on attitudes to the unnecessary deaths of hundreds of thousands of wildfowl.Producer Adrian Washbourne

Jim McDonald grew up in Glasgow. He was the son of a rope-maker and the first in his family to go to university. Now he’s the Principal of Strathclyde University, a non-executive director of Scottish Power and President of the Royal Academy of Engineering. He worked in the electrical power industry for many years before becoming an academic. Much of his life has been spent making sure that we all have access to the electricity we need, when we need it. That includes when the sun doesn’t shine and the wind doesn’t blow! As we rely more and more on renewable energy and more of us start driving electric cars, making sure the National Grid is fit for purpose is going to be a real challenge. But Jim is on the case.
