Genetically Modified Mosquito

I'm kind of a middle grounder, I suppose, on the subject of improving life through genetic modification (GM). GM food sources are a bit scary, less for me because of what happens when you ingest them, but because of the unknowns of what might happen in the surrounding ecosystem when you grow them. This article about a GM mosquito falls in that disturbing camp.

Scientists in America have engineered a species of mosquito which is resistant to the malaria infection. Its ability to block the infection suggests that it could come to dominate mosquito populations if released into the wild.

More interesting, and much more appealing, however, is the competitor's approach:

A different approach has been adopted by a British team, led by Andrea Cristiani, of Imperial College, London. His team has developed a GM mosquito in which the males have fluorescent testicles, allowing them to be easily identified and sterilised.

Now there's some technology that might have some crossover potential for sex offender treatment programs.
