Bio-engineered mosquitoes could be the key to wiping out the malaria virus, which kills around 830,000 people every year.

UK group Oxitec has developed the “Friendly Mosquito”, a male insect that will mate with a female, only for the resulting offspring to die before they reach adulthood. Only female offspring will die, since only female mosquitoes bite. The male offspring will survive and continue to spread the “self-limiting gene.”
