Researchers from Hanns-Christoph Nägerl's group have produced the world's first ultracold KCs molecules in their absolute ground state. Starting by mixing clouds of potassium and cesium atoms cooled ...

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), ...

These days it seems almost trivial to cool atoms down to near absolute zero temperatures in a lab, but what is the lowest possible naturally occurring air temperature on this planet?
