Scientists divided over new research method to combat malaria

Work on engineered gene used to modify DNA of mosquitoes 'could be stifled' by perceived risk to environment

Research on a radical new way to combat malaria and other devastating diseases could be knocked off track if a UN biodiversity conference imposes a moratorium on the work, a group of scientists have said.

Some scientists believe the different approach has the potential to transform the battle against malaria. It involves engineered gene drives which are used to modify the DNA of wild organisms on a mass scale. In the case of mosquitoes the method would have the potential to wipe out populations of certain species which carry the malaria parasite, say the scientists.
