Harvesting Babies' Stem Cells

Available for over a year

Collecting embryonic tissue from newborns is a growing business, but how likely is it to actually protect the child against life-threatening diseases in the future? The BBC's Suranjana Tewari reports from India, where the practice is taking off. Meanwhile back in the UK, presenter Ed Butler hears from a sceptical stem cell researcher - Axel Behrens of the Francis Crick Institute. Plus, the joys and applications of modern day mapping technology, with Nigel Clifford, head of Britain's Ordnance Survey, and Rohan Richards of the National Spatial Data Management Division in Jamaica.
