Well, it's not yet confirmed... That error would be worse than the magnetic moment of the muon about 10 years ago. There, it was "at least" a conflict of conventions used in the computer codes!

In a statement based on an earlier press release from the OPERA collaboration, CERN said two possible "effects" may have influenced the anomalous measurements. One of them, due to a possible faulty connection between the fiber-optic cable bringing the GPS signals to OPERA and the detector's master clock, would have caused the experiment to underestimate the neutrinos' flight time, as described in the original story. The other effect concerns an oscillator, part of OPERA's particle detector that gives its readings time stamps synchronized to GPS signals. Researchers think correcting for an error in this device would actually increase the anomaly in neutrino velocity, making the particles even speedier than the earlier measurements seemed to show. CERN's statement says OPERA scientists are studying the "potential extent of these two effects" but doesn't indicate which source of error (if either) is likely to outweigh the other. However, Lucia Votano, director of the Gran Sasso laboratory, says the "main suspicion" focuses on the optical-fiber connection. She adds that OPERA researchers deserve credit for "having tenaciously followed this particular evidence via checks completed in the last few days." The two effects will get a new round of tests in May, when the two labs are scheduled to make velocity measurements with short-pulsed beams designed to give readings much more precise than scientists have achieved so far.

"One of the leading theories describing how the most energetic cosmic rays are produced may need a rethink in light of a new study by physicists at the IceCube Neutrino Observatory in Antarctica. The team had set out to detect the extremely energetic neutrinos that are expected to be produced alongside high-energy cosmic rays in the violent explosions that mark the deaths of massive stars - but after looking at hundreds of these explosions, no such neutrinos have been found. "

IceCube detects a neutrino in about every 6 minutes but most are from within the solar system. A small number of very high energy neutrinos have been found though which have energies that cannot be produced by the sun or on Earth.

Sante, Luzi have a look at this???!!!

Leo, you mean that they measured 3 years? That's not a point to criticize: since the only interaction of neutrinos with matter is the Weak Interaction (which is indeed very, very weak), it is extremely hard to get a reasonable statistic. By the same reason, it's essentially impossible to shield the experiment from the background. And this background (solar neutrinos, cosmic radiation neutrinos) is huge.

for sure a result to be taken seriously. It makes a buzz in my lab... but always be cautious with this kind of declaration, that hugely violates all physics we know and even most of the reasonable alternative theories... Remember the Pionneer anomaly for which it took almost ten years to set up that finally its a thermal effect.

Not new but still crazy: neutrinos explored as a source of some mass extinctions.

I did not even know about the existance of the station ... fantastic results it seems ...

...obvious use for space...

Indeed, you only need ONE antenna to communicate with your satellite irrespective of its position, since one can freely send the signals right through the Earth. Small disadvantage: you should tell the launcher section to design a new launcher that is capable to bring a 200tons detector to space...

The end is near...

Some quotes: "Our results are in agreement with what Einstein would like to have" - they called him just to double-check... "How many times do you have to say 'zero' to make sure it's zero?" - because statistics is just not trendy any more...

ESA involvement in device central to neutrino speed measurement

Sante: did you see this?

Maybe a stupid question: The authors argue with the results obtained by Cohen and Glashow [2]. In [2] ist was stated that superluminal neutrinos should lose energy by producing photons and e+e- pairs. This should be observable. These conslusions are based on known physics (I guess), i.e. on the laws valid for subluminal conditions. How reasonable is it to apply (i.e. to assume the validity of) the same laws for superluminal particles?

The ice-cube observatory in Antarctica reveals the source of high energy cosmic neutrinos. Spoiler: its Blazars!

Hate spoliers!

An experiment at the Fermi National Accelerator Laboratory near Chicago has detected far more electron neutrinos than predicted - a possible harbinger of a revolutionary new elementary particle called the sterile neutrino, though many physicists remain skeptical.

Awesome video!!!

The effect of gravity on virtual electron-positron pairs as they propagate through space could lead to a violation of Einstein's equivalence principle, according to calculations by James Franson at the University of Maryland. While the effect would be too tiny to be measured directly using current experimental techniques, it could explain a puzzling anomaly observed during the famous SN1987 supernova of 1987.

Seems like those particles have some use...
