Today In Politics: Australian Nerds Invent a Tractor Beam


If you read one more thing today before you uninstall your internet, because of boredom, let it be this:

Researchers from the Australian National University have announced that they have built a device that can move small particles a meter and a half using only the power of light.

Physicists have been able to manipulate tiny particles over miniscule distances by using lasers

for years. Optical tweezers that can move particles a few millimeters are common.

Andrei Rhode, a researcher involved with the project, said that existing optical tweezers are able to move particles the size of a bacterium a few millimeters in a liquid. Their new technique can move objects one hundred times that size over a distance of a meter or more.

We are not scientists but an object "one hundred times" the size of a bacterium still sounds really, really small.

At any rate, you are welcome!
