The daily disposable contact lens

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)

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?''.

Mike Lanchin has been hearing from one Iraqi woman whose four children were inside the air raid shelter the day it was bombed.
