Magnetism Used to Reverse Heat Flow
Edwin Cartlidge, Nature News
The strange world of quantum mechanics just got a little stranger with the discovery that a magnetic field can control the flow of heat from from one body to another. First predicted nearly 50 years ago, the effect might some day form the basis of a new generation of electronic devices that use heat rather than charge as the information carrier.
