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 ...

David Reilly and his University of Sidney team developed a silicon chip that can control spin qubits at milli-kelvin temperatures. That’s just slightly above absolute zero (-273.15 degrees Celsius), ...

I am typing this from the Atlanta area right now, and it’s cold. In fact, the current temperature at my house is 9 degrees F and the winds are roughly 24 mph. That means it feels like -5 degrees F ...

A set of four mirrors used by the Laser Interferometer Gravitational-Wave Observatory (LIGO) to detect ripples in space-time have been cooled down so much that they are nearly at their minimum-energy ...
