MAKING LIGHT OF MOSQUITOES
In the era of sci-fi, it wouldn’t be tough to imagine a tent made of laser that would protect you from harm. Now Szabolcs Marka, an associate professor of physics at Columbia University in the US, has almost made it a reality. He has developed a light shield that repels mosquitoes. The laser interferes with the insect’s power to sense humans via light and heat. He has already got $1 million from the Bill and Melinda Gates Foundation, one of whose aims is malaria eradication. Marka and his team are working to develop a device that that can be placed where mosquitoes hide.
