In a paper released today in Science Advances, Australian researchers describe the first observation of a native ferroelectric metal: a native metal with bistable and electrically switchable spontaneous polarization states-the hallmark of ferroelectricity.  Electric generators have a plethora of uses-ranging from automotive to aircraft to microgrids. There is currently a strong desire to reduce the size and increase the efficiency of the devices.  The high resolution and wealth of data provided by an experiment at Diamond can lead to unexpected discoveries.  Researchers at The Ohio State University have discovered how to control heat with a magnetic field.  Researchers at the University of Illinois at Urbana-Champaign have developed a new technology for switching heat flows 'on' or 'off'.  Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest tools: a pencil, photocopy paper, and conductive paint.  A team of researchers with the University of California and SRI International has developed a new type of cooling device that is both portable and efficient.  Thermal conductivity is one of the most crucial physical properties of matter when it comes to understanding heat transport, hydrodynamic evolution and energy balance in systems ranging from astrophysical objects to fusion plasmas.  Researchers from the Theory Department of the MPSD have realized the control of thermal and electrical currents in nanoscale devices by means of quantum local observations.  Physicists have proposed a new type of Maxwell's demon-the hypothetical agent that extracts work from a system by decreasing the system's entropy-in which the demon can extract work just by making a measurement, by taking advantage of quantum fluctuations and quantum superposition.  Pioneering research offers a fascinating view into the inner workings of the mind of 'Maxwell's Demon', a famous thought experiment in physics.
