Will Russia change the clock to winter time this autumn? [br]

The world’ s first genetically modified chickens that do not spread bird flu have been created by British scientists. Writing in the journal Science, the researchers say they’ve developed the birds with an artificial gene.

Professor Helen Sang of Edinburgh University says genetic modification is potentially a much better way of protecting against diseases than vaccination because it works even if the virus mutates.
