Could GM cows solve the problem of milk allergies?
Scientists in New Zealand have produced a genetically modified cow whose milk is less likely to make people allergic to it, according to the BBC.
The milk that the cow produces doesn't contain beta-lactoglobulin, a protein which causes allergic reactions. Up to 3% of children can be allergic to cows milk, as the protein isn't in mothers' milk.
Some scientists have heralded the discovery, but people have said it could raise ethical issues, especially as the cow was born without a tail.
A scientist who worked on the famous cloning of Dolly the sheep has spoken out in support of the genetic modification. Prof Keith Campbell, from the University of Nottingham, said: "It's very interesting and its another way of showing the technology can be pushed forward with potentially useful outcomes.
"There are zero risks in my opinion. If it was poisonous, the animal would be dead."
However Pete Riley, from campaign group GM Freeze, said: "Before this goes any further, they need to establish what the cause of the defect in the calf was, as there is a possible link to the GM approach."
