As the winter is approaching, it is difficult to see the mosquitoes nowadays. But in the summer, it is absolutely annoying for mosquitoes to fly around. Even if mosquito repellent mosquito repellent is not used, then what are the coup? Szabolcs Márka, an assistant professor at Columbia University, discovered through experiments that lasers can disturb the direction of mosquitoes. When Marka was doing the optical part of astrophysics research, he discovered the laser's mosquito repellent effect by coincidence, but at the time he did not know the specific reason for the laser to drive off the mosquitoes. Because of this discovery, he has received two generous grants from the Bill and Melinda Gates Foundation over the past few years, and he is now working on a commercial "laser barrier" to expel mosquitoes. In this way, as long as people cover this protective barrier outside the house, mosquitoes cannot enter home. Now Marka and his wife and colleagues are working hard to break through the various problems in this invention. It may not be possible to form within a few years. But as long as their plans are feasible, Bill Gates will provide financial support. Research, after all, laser repellent is one of the potential weapons to eliminate malaria. However, if the laser repellent is to be widely used, its price must be very low. Most mosquito-infested areas are poor areas.
