LED lightbulbs have slashed the amount of energy we use to light our homes. New data illustrate just how much. Still have doubts about whether LED lightbulbs are actually worth it? Consider this. In ...

Physicists from Trinity College Dublin believe new insights into the behavior of light may offer a new means of solving one of science's oldest challenges—how to turn heat into useful energy. Their ...

When light interacts with metallic nanostructures, it instantaneously generates plasmonic hot carriers, which serve as key intermediates for converting optical energy into high-value energy sources ...

Deep in the sun’s core, two protons of hydrogen atoms collide violently. Under immense pressure they fuse together and release vast amounts of energy in a process known as nuclear fusion. Travelling ...
