Radiation is the motion of energy through space as waves or particles.
When endangered Hainan gibbons started making risky leaps across an area mowed down by a landslide, researchers provided them a rope bridge.
Solar power is a way to harness energy from the sun, and lessen our reliance on fossil fuels.
An accidental discovery helps scientists generate electricity out of thin —but humid — air with bacteria-made protein nanowires.
A new device exploits the contrast between bright spots and shade to produce a current that can power small electronics.
Researchers have mimicked the first stages of planet formation in the lab. All they needed were glass beads and a catapult.
Researchers have upped the efficiency of layered solar cells that could be printed or painted onto surfaces. Now they are working to make them more rugged.
These chemistry terms tell us if a molecule is more likely to give up a proton or pick up a new one.
Splitting Erwin Schrödinger’s famous — and fictitious — cat between two boxes brings scientists one step closer to building quantum computers from microwaves.
