Researchers from four universities in Germany have conditioned a lab to register the coldest effective temperature in a research-controlled environment ever recorded—38 trillionths of a Kelvin above ...

Absolute zero is often thought to be the coldest temperature possible. But now researchers show they can achieve even lower temperatures for a strange realm of "negative temperatures." Oddly, another ...
