(PhysOrg.com) -- Engineers have built the first carbon nanotube (CNT) transistor with a channel length below 10 nm, a size that is considered a requirement for computing technology in the next decade. Not only can the tiny ...
Until recently, it was widely believed among physicists that it was impossible to compress light below the so-called diffraction limit (see below), except when using metal nanoparticles, which unfortunately also absorb light. ...

When two galaxies collide, the supermassive black holes at their cores release a devastating gravitational "kick," similar to the recoil from a shotgun. New research led by CU Boulder suggests that this kick may be so powerful ...

(Phys.org)—It was a an interesting week for physics as a team with the Australian National University conducted an experiment that confirmed quantum theory weirdness—they carried out John Wheeler's famous delayed-choice ...
Graphene—which consists of atom-thick sheets of carbon atoms arranged hexagonally—is the new wonder material: Flexible, lightweight and incredibly conductive electrically, it's also the strongest material known to man.
