For two centuries, engineers have trusted a simple rule to predict how heat flows through solids, from jet-engine blades to smartphone chips. Now a set of carefully designed experiments has revealed a ...

For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat. Now a series of experiments at atomic and electronic scales is revealing ...

Scientists have discovered an exception to a 200-year-old natural law in science. Researchers at the University of Massachusetts Amherst were looking at Fourier's Law—the law of heat conduction that ...
