Spiders may help us root out malaria
Researchers at the University of Maryland have used funnel-web spider genes to create a genetically modified fungus with venom that can kill malaria-carrying mosquitos rapidly. In experiments, entire mosquito populations were nearly eradicated in just 45 days. Malaria — a disease that affects roughly 200 million people a year and kills 400,000 — has been more difficult to contain in recent years as mosquitoes have developed resistance to insecticides. But critics warn that such a fungus risks killing other organisms, damaging the ecosystem.
