Medicine in the News: Genetically modified mosquitos?

In the era of being able to genetically modify everything.....are we completely aware of the long term effects on the fine balance of our ecosystem?? Genetically Modified mosquitos are programmed to die before reaching adulthood. The plan is that they will mate with other mosquitos and spread their early death capabilities. The intention being a safer way of mosquito control than spraying. Also, potentially eradicating diseases spread by adult mosquitos such as Malaria, Dengue Fever etc. I see the positives, now what are the negatives??? See what the NY Times has to say on the subject!
