The thermal noise of the electric current has been well known for almost a century. In an article published this week in Physical Review Letters, a group of researchers from the Low Temperature Laboratory of Aalto University (Finland) and Technical University of Delft (The Netherlands) show that also fluctuations of temperature may contribute to the current noise.
