Bug-zapping laser will only kill bad insects
There are good insects, and then there are bad bugs. And the folks at Seattle-based Intellectual Ventures Lab (IVL) have been working on a device that will only kill pests and leave the others unharmed. It's called the Photonic Fence, and has been in development as early as 2009, but according to a Wired report, it's recently been "installed on a US Department of Agriculture site in the state for its first real-world test." If all goes well, IVL plans to market the Fence to farmers who need to protect their crops from pests.
