Quantum 'backwards heat' experiment hints thermodynamics may need rewriting

A series of quantum physics experiments and theoretical papers now suggest that heat can flow spontaneously from a cold ...

Plasma rotation simulations could help fusion reactors survive decades of use

Scientists have long seen a puzzling pattern in tokamaks, the doughnut-shaped machines that could one day reliably generate electricity from fusing atoms. When plasma particles escape the core of the ...
