Here attention is drawn to a recent article in the journal Nature which claimed that researchers had cooled a system to a temperature below absolute zero. It is pointed out that this was not the claim in the original paper and is incorrect as far as the accepted definition of temperature is concerned. It is pointed out also that, if the claim were true, then it would imply that both the Third and Second Laws of Thermodynamics had been violated.
