An Italian physicist at the head of a team that made a cautious but hugely controversial claim that neutrinos may travel faster than the speed of light resigned on Friday following calls for his dismissal.

One of the strange features of quantum information is that, unlike almost every other type of information, it cannot be perfectly copied.

An attempt to repeat an experiment that showed a subatomic particle traveling faster than the speed of light suggests that the earlier result may have erred, and that Einstein s famed special theory of relativity remains intact.

(PhysOrg.com) -- A group of scientists led by researchers from the University of Rochester and North Carolina State University have for the first time sent a message using a beam of neutrinos – nearly massless particles that travel at almost the speed of light.

(PhysOrg.com) -- When most of us think of an atom, we think of tiny electrons whizzing around a stationary, dense nucleus composed of protons and neutrons, collectively known as nucleons. A collaboration between the U.S. Department of Energy's Argonne and Thomas Jefferson National Laboratories has demonstrated just how different reality is from our simple picture, showing that a quarter of the nucleons in a dense nucleus exceed 25 percent of the speed of light, turning the picture of a static nucleus on its head.

(PhysOrg.com) -- Physics researchers at the University of Kansas have discovered a new method of detecting electric currents based on a process called “second-harmonic generation,” similar to a radar gun for electrons that can remotely detect their speed.

Multiferroic materials have attracted much interest because of their ability to control magnetism through the application of a voltage. This ability can be utilized to reduce the power required by electronic devices and to increase their speed

(PhysOrg.com) -- A team of researchers have devised a means for observing the speed with which quasiparticles can travel through an optical lattice. The experiment performed at the Max-Planck-Institut f

Study of 1,700 men over 70 sought to clock the speed of the Angel of Death

Einstein’s explanation of special relativity, delivered in his 1905 paper On the Electrodynamics of Moving Bodies focuses on demolishing the idea of ‘absolute rest’, exemplified by the theoretical luminiferous aether. He achieved this very successfully, but many hearing that argument today are left puzzled as to why everything seems to depend upon the speed of light in a vacuum.

Some say that the reason you can't travel faster than light is that your mass will increase as your speed approaches light speed – so, regardless of how much energy your star drive can generate, you reach a point where no amount of energy can further accelerate your spacecraft because its mass is approaching infinite.

Two books and a podcast series explore how we can improve our minds.

By Eugenie Samuel Reich of Nature magazine The claim that neutrinos can travel faster than light has been given a knock by an independent experiment. On 17 October, the Imaging Cosmic and Rare Underground Signals (ICARUS) collaboration submitted a paper to the preprint server arXiv.org, in which it offered a rebuttal of claims to have clocked subatomic particles called neutrinos traveling faster than the speed of light.

Oh, yeah. Moving faster than the speed of light has been the hot topic in the news and OPERA has been the key player

(PhysOrg.com) -- It's been just two weeks since the Oscillation Project with Emulsion-tRacking Apparatus (OPERA) team released its announcement claiming that they have been measuring muon neutrinos moving faster than the speed of light, causing an uproar in the physics community.
