" British scientists have developed genetically modified (GM) chickens that cannot transmit bird flu infections -- a step that in future could reduce the risk of avian flu spreading and causing deadly epidemics in humans.
Scientists from Cambridge and Edinburgh universities said that while the transgenic chickens still got sick and died when they were exposed to H5N1 bird flu, they didn't transmit the virus to other chickens they came into contact with."
