Future chicken cutlets may come from birds that have been genetically modified to resist bird flu, after a breakthrough in Britain announced this week. Researchers have produced chickens that cannot spread avian flu to other chickens, a major step toward protecting birds — and humans — from the deadly virus.
The transgenic cluckers still died from bird flu, however, so there’s still much more to be done before scientists produce a truly flu-free bird.
In a case with major implications for the future of food, the FDA is poised to decide this week whether it is OK to sell and eat supersalmon whose DNA has been deliberately altered. It would be the first time genetically modified animals would be legal to sell for human consumption. So in the near future, the lox on your morning bagel might be something pretty different from what nature intended — and you might never know it.
Japanese biologists have made genetically modified primates that can pass the modification to their offspring -- a first for science. The researchers, reporting in Nature, introduced a jellyfish gene to marmosets that made their skin glow green under UV light, a quick, harmless test of the technique's success. The goal is for future marmosets to bear genes for human disease. Such colonies of research animals may model neurological disorders far better than lab mice.
