Researchers developed a memristor with metal-dielectric layers that remembers electrical signals. Its metal-dielectric ...

Researchers designed a photonic crystal that changes and records colors, heals itself, and adheres to surfaces, offering exciting possibilities for sensors and anti-counterfeiting.

A supernova observed in 1181, lost for centuries, was recently rediscovered. Its 3D structure and expansion speed show ...

To give you an idea how small this is, if you line up 7 oxygen atoms or 3-4 water molecules, you'll get about one nanometer. But that's hard to imagine either. How about this: a red blood cell is ...
