UCLA engineers have unveiled a novel solid-state thermal transistor capable of rapidly switching heat flows on and off using an electric field—a long-sought innovation that could usher in a new era of advanced heat management technologies. The research team's room-temperature thermal transistor demonstrated record-high speeds, switching cycles, and...
A substance called antimatter is at the heart of one of the greatest mysteries of the universe. We know that every particle has an antimatter companion that is virtually identical to itself, but with the opposite charge. When a particle and its antiparticle meet, they annihilate each other...
Researchers in the US have finally fulfilled an objective that was set decades ago: the achievement of “ignition” – getting more energy out than you put in – using nuclear fusion. The scientists at the Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), where the experiment took place,...
