Odd quantum property may let us chill things closer to absolute zero

We can already cool objects with fridges and with lasers. Now there is a third cooling technique involving special quantum states – and it could, in theory, allow us to reach the lowest temperatures yet

Heating and cooling seem to be fundamentally different, not opposites

Conventional thermodynamics says that heating and cooling are essentially mirror images of each other, but an experiment with a tiny silica sphere suggests otherwise
