Malaria kills – especially children, taking at least one child every thirty seconds. However, scientists are hard at work developing laser technology to fight the terrible disease. The laser gun or Weapon of Mosquito Destruction (WMD) has the potential to stop malaria by destroying mosquitoes with one shot.
In 2007, scientist Lowell Wood met with other scientists and suggested using old laser technology to destroy mosquitoes. The laser is modeled after a weapon developed to protect the U.S. from Soviet missiles in the 1980s. But the technology was never used. Then in 2008, scientists used a laser to kill a different airborne threat-the mosquito.
How does the weapon work? With the help of a computer, a laser burst burns off the insect's wings, sending the bug to the ground. The machine is even able to distinguish between male and female mosquitoes based on the sound frequency of the wings. Currently, scientists are experimenting with the strength of the laser so that it will not harm other insects and creatures. If the scientists are successful, houses and villages could be surrounded by laser barriers. These barriers would kill mosquitoes stopping the spread of malaria.

Mosquito Facts
Only female mosquitoes bite people: male mosquitoes feed on plant nectar. Mosquitoes are attracted to human breath.
A female mosquito can lay 200 eggs at one time. These eggs can survive for more than five years. Mosquitoes are drawn to dark clothing.
When mosquitoes bite, they release chemicals into your skin that make your skin itch.
