A multi-million pound research centre dedicated to investigating birth defects opens in the capital today.
The Newlife Birth Defects Research Centre is Europe's first centre to examine the diagnosis and treatment of birth defects.
The centre, based at University College London's Institute of Child Health, was funded through donations given to Great Ormond Street Hospital Children's Charity.
Professor Andrew Copp, head of the centre, said: "We are able to prevent only a very small number of birth defects. We remain ignorant of what actually causes common birth defects such as cleft palate, heart defects and spina bifida."
