If you read the whole article, you would'nt have to ask the question! However, to make it simpler for you, let me quote a couple of relevant paras.
" In the most recent trial in Brazil - in a town called Mandacaru - the company has reported a 96% reduction in the dengue mosquito (Aedes aegypti) population.
The scientists use almost identical technology in their fruit fly research, with the ultimate aim of rearing a female-killing strain of GM male flies".
If you cannot see the link between the two, and similarly don't understand how eliminating the anopheles mosquito (yes, I know the dengue-carrying mosquito is different to the anopheles mosquito, but the process for anopheles is similar, and engue fever itself is a major killer and spreading rapidly worlwide) will save three million lives a year, then there is no hope for you! You try to make a clear distinction between medicine and science (in this case GM research and application), without understanding that the two are closely intertwined. You wouldn't have modern medicine without modern science. Are analytical machines medicine? When they are analysing your blood for problems, or scanning your body for issues, is that medicine or science? When - following years of scientific research in the lab - drug companies come up with new drugs that - for example - extend the lives of AIDs patients by tens of years, is that medicine or science? When they introduce GM genes into your marrow to change genetic faults - is that medicine or science?
Saving the lives of three million people a year seems to me to be good medicine, however it originates!
