The world's deepest dive 11km down

Don Walsh was the first to go to the very bottom of the deepest part of the ocean in 1960 in a specially designed submarine, the Bathyscaphe Trieste. The water pressure was 800 tonnes per square inch, and the successful mission to "Challenger Deep" in the Mariana Trench under the western Pacific, was a technological breakthrough in marine engineering. Don Walsh describes the dive to Rebecca Kesby, and explains why understanding the deep ocean is crucial in the fight to reduce climate change. (Photo: The Bathyscaphe Trieste in 1960. Getty Images)

Ireland's bank bailout

In the wake of the 2008 global financial crisis Ireland had to borrow billions to stop its banks from going under and to keep its economy afloat. The IMF, the EU and the European Central Bank provided the money. Matt Murphy has been speaking to Patrick Honahan, who was Ireland's central banker at the time of the bailout.

Acid rain

In the 1960s, Swedish scientists documented how acid rain was poisoning lakes, killing fish, damaging soils and forests. Crucially they said it was an international problem, because the acid rain was caused by industrial pollution being carried on the prevailing winds from countries thousands of miles away. Acid rain is primarily created by the burning of fossil fuels, particularly coal, which releases large amounts of sulphur dioxide and nitrogen oxides into the air. These particles then mix with moisture in the atmosphere to create sulphuric and nitric acid, which then falls back to earth as acid rain. The phenomenon of acid rain was noticed in the 19th century but the threat was largely ignored. Alex Last spoke to Prof Henning Rodhe of Stockholm University about the research that alerted the world to the dangers of acid rain.Photo: Forest decline caused by acid rain in the Giant Mountains in Poland - 1998 (Getty Images)

The Immortal Cells of Henrietta Lacks

The story of an African American woman who played a largely unsung role in countless medical breakthroughs over more than half a century. Henrietta Lacks had cells taken from her body in 1951 when she was suffering from cancer. Those cells were found to be unique in a most particular way. They continued to reproduce endlessly in the laboratory. Culture from those cells have since been used in thousands of scientific experiments. But as Farhana Haider reports, Henrietta herself was never asked if her cells could be used in medical research.(Photo: Henrietta Lacks. Copyright: Lacks Family)

Britain's forgotten slave owners: Part two

How one man used research by historians at University College London into Britain's forgotten slave-owners to track down the descendants of the family who'd owned his ancestors two centuries earlier. Dr James Dawkins tells Louise Hidalgo how his quest led him to the famous evolutionary biologist, Professor Richard Dawkins, author of the Selfish Gene, with whom he shares a name and a past.Picture: slaves unloaded from slave ship at their destination; from Amelia Opie The Black Man's Lament: or How to Make Sugar, London, 1826 (Credit: Universal History Archive/Getty Images)

Britain's forgotten slave owners: Part one

It wasn't until recently that researchers working in the national archive in London discovered the extent to which ordinary people in Britain had been involved in the slave trade in the 18th and early 19th century. Louise Hidalgo has been talking to Dr Nick Draper, who uncovered volumes of records detailing the thousands of people who claimed compensation when slavery was abolished in Britain in 1834. He and colleagues at University College London set up the Legacies of British Slave-ownership database, documenting this forgotten part of Britain's history.(Photo: Taken from Josiah Wedgwood's medallion, 'Am I Not a Man and a Brother?''.
