(Newser) – A team of physicists say they’ve managed to “tie light in knots” using holograms and abstract mathematics. The breakthrough could have a host of practical applications, including more precise lasers and traffic speed guns. It’s also the first physical application of “... Read full story »

Scientists Teleport Data on Tiny Scale

Send information between atoms a meter apart

(NEWSER) - It’s not quite worthy of the Starship Enterprise, but Maryland scientists have managed to teleport data on an atomic scale, LiveScience reports. The researchers transmitted information between atoms a meter apart without the data actually crossing that space—a development that could help create speedy quantum computers and highly secure communication, Science News notes.

Einstein Safe: Neutrinos Do Not Break Light Speed

New experiment shows particles at identical speed with light

(NEWSER) - Einstein's theory apparently remains untouchable, and flabbergasted theoretical physicists can cease hyperventilating: Neutrinos do not exceed the speed of light, but they do appear to travel at the same speed as light, according to the results of a recent experiment. The new data confirm Einstein's foundational ideas and refute an experiment from last September which showed neutrinos exceeding the speed of light, threatening to turn the world of physics upside down, reports BBC News .

Einstein Wrong? Maybe Just Faulty Wiring

A simple loose cord may explain last year's controversy

(NEWSER) - More evidence that last year's furor over the accuracy of Albert Einstein's work got blown way out of proportion: Physicists believed they'd seen particles traveling faster than light , a phenomenon that would disprove the theory of relativity. But the controversial observations may have been the result of nothing more than a loose wire, experts say. A GPS error may have caused the mistake, says a scientist at CERN, where the initial results were reported. More»

Video Gamers Unlock AIDS Molecule Puzzle

'They did it in less than 10 days': scientist

(NEWSER) - Video gamers have figured out a molecular puzzle that has long baffled scientists and may lead to crowd-sourced cures for AIDS and other illnesses, MSNBC reports. In a surprising step for so-called citizen science, players of the online game Foldit discovered the molecular structure of an enzyme in an AIDS-like virus found in monkeys. All it took was 12-15 dedicated gamers. "They actually did it in less than 10 days," says biochemist Firas Khatib. More»

Scientists Slay Superbugs... With Light

Wavelengths cause chemical reaction, researchers find

(NEWSER) - Scientists have shed light on a new way to kill hospital superbugs like MRSA: literally shed light on them. A set of wavelengths called HINS-light acts by stimulating molecules in the bacteria, causing them to create chemicals that kill the germs. In trials, the process appears far more effective than “cleaning and disinfection,” the Daily Mail reports. More»
