"An Italian experiment has unveiled evidence that fundamental particles known as neutrinos can travel faster than light. Other researchers are cautious about the result, but if it stands further scrutiny, the finding would overturn the most fundamental rule of modern physics—that nothing travels faster than 299,792,458 meters per second.
The 1,800-tonne OPERA detector is a complex array of electronics and photographic emulsion plates, but the new result is simple— the neutrinos are arriving 60 nanoseconds faster than the speed of light allows. "We are shocked," says Antonio Ereditato, a physicist at the University of Bern in Switzerland and OPERA's spokesman."

How fast do quantum interactions happen? Faster than light, 10,000 times faster.
That's what a team of physicists led by Juan Yin at the University of Science and Technology of China in Shanghai found in an experiment involving entangled photons, or photons that remain intimately connected, even when separated by vast distances.They wanted to see what would happen if you tried assigning a speed to what Einstein called "spooky action at a distance."
the researchers entangled two photons and sent them to two different stations about 10 miles (16 kilometers) apart. In their ArXiv paper, the scientists said that previous experiments had "locality loopholes," which is another way of saying that it's possible to explain the link between photons with something other than the "action at a distance."
The group measured the state of one photon and timed how long the entangled state took to show up in the other. They found that the slowest possible speed for quantum interactions is 10,000 times the speed of light — assuming your experiment is moving relatively slowly, at least relative to light beams."

Electric signals can be transmitted at least four times faster than the speed of light using only basic equipment that would be found in virtually any college science department.
Scientists have sent light signals at faster-than-light speeds over the distances of a few metres for the last two decades – but only with the aid of complicated, expensive equipment. Now physicists at Middle Tennessee State University have broken that speed limit over distances of nearly 120 metres, using off-the-shelf equipment costing just $500.
