Tiny fridge aims big

Abstract:
Physicists in the US have made a chip-sized refrigerator that can cool objects much bigger than itself to millikelvin temperatures. The device relies on the quantum mechanical tunnelling of electrons between a metal and superconductor and could find applications in a variety of cryogenic sensors in the semiconductor industry and astronomy.
