Summary:Decades of hotly-contested research are coming to a close as the identity of the agent which causes Creutzfeldt Jakob Disease (CJD) in humans,BSE in cattle,and scrapie in sheep,is at last defined. The programme shows how new techniques - particularly the ability of scientists to add or subtract genes at the fertilised egg stage of an animal's reproduction (while a single cell) - are resolving one of 20th century biology's greatest mysteries. Scientists hope this will lead to a better understanding of a process which may well underlie more common neurological diseases such as Alzheimer's.
