    GM mosquitoes cut rate of viral disease in Brazil

    Adults males carrying the altered gene cannot father young that survive to adulthood. That’s when they suck blood — and can transmit disease.

    Genes: How few needed for life?

    Scientists rebuilt a microbe using its old genes. But not all of them. They used as few building-blocks as they could get away with and still have the life-form survive.
