World's coolest chip runs at near absolute zero
How do you find out what happens to physics near absolute zero (aka 0 kelvin), the temperature where particle motion virtually stops? Scientists at the University of Basel might have just the device to do it. They've developed a nanoelectronics chip that they can successfully cool to a record-setting, bitterly cold 2.8 millikelvin. The trick involved a clever use of magnetic fields to eliminate virtually all sources of heat.
