It may soon be possible to control the spread of malaria by altering the DNA of wild mosquitoes, researchers said.
In a laboratory, researchers made a gene spread from a few mosquitoes to a population of mosquitoes. When the right gene is spread, it may help control the spread of malaria.
Professor Andrea Crisanti, from the department of life sciences at Imperial College London, said: "This is an exciting technological development, one which I hope will pave the way for solutions to many global health problems."
Nearly a million people die of malaria annually.
