A former chief scientific adviser to the government, Lord May of Oxford, has hit on a novel idea for making genetically modified foods acceptable to the public. Speaking in his role as president of the Royal Society, he told members last week:"I think it likely that the general public, very sensibly, will engage more fully in this debate once, as it were, GM offers a golden apple, the eating of which will make you thin and witty." Sounds like old Bob's had a whole bagful of these fantastic fruit.
