A Laser-Powered Nanosensor Could Spot Extra-Terrestrial Life
This may look look like an incredibly simple little device—because, well, it is—but don’t be fooled. This laser-powered nanosensor can spot the movement of the tiniest of objects, and it could help us identify extra-terrestrial life. In fact, it’s a simple cantilever which contains a laser motion sensor. As bacteria pass through it, they cause…
