From the BBC:
UK scientists have developed genetically modified chickens capable of laying eggs containing proteins needed to make cancer-fighting drugs.
The breakthrough has been announced by the same research centre that created the cloned sheep, Dolly.
The Roslin Institute, near Edinburgh, says it has produced five generations of birds that can produce useful levels of life-saving proteins in egg whites.
The work could lead to a range of drugs that are cheaper and easier to make.
Oh yeah, genetic experimentation is Eeeeevil.
