Killing mosquitos with lasers…
When an invading insect is detected, our software identifies it by training a nonlethal laser beam on the bug and using that illumination to estimate the insect’s size and also to measure how fast its wings are beating. Using this method, the system can not only distinguish among mosquitoes, butterflies, and bumblebees, but it can even determine whether a mosquito is male or female! (Females are significantly larger than males and have slower wingbeats.) This is useful because only female mosquitoes bite humans.
Our software is able to track a mosquito in flight once it establishes that it is a valid target. After running safety checks to ensure no unintended object is in view, the system activates a second, more powerful laser that zaps the mosquito, causing death either by damage to its DNA (an unconfirmed hypothesis) or by overheating. The energy levels and light frequencies used are not capable of damaging human tissue, but even so, we’ve built in safeguards that ensure that the system doesn’t fire when anything much larger than a mosquito is in the photonic fence.
The cool thing is, it’s not developed for rich people in industrial nations, but to fight Malaria everywhere on the planet:
In 2007, the Bill and Melinda Gates Foundation asked Intellectual Ventures to create new technologies that will not only fight malaria but will eventually eliminate this scourge of humanity altogether. Already our team of entomologists, epidemiologists, physicists, and other scientists have come up with innovative approaches that attack the parasite that causes the disease from several angles. Some make it easier to diagnose the disease quickly and accurately. Others destroy the parasites directly. Still others target the mosquitoes that serve as hosts to the parasites and spread malaria from person to person.
We believe that introducing the right combination of these technologies—while keeping older approaches in place—will lead to a real chance of completely eradicating malaria.
