GlowingCat (2459788) writes "Physicists at The Australian National University (ANU) have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach. The team, led by Dr Horst Punzmann, discovered they can control water flow patterns with simple wave generators, enabling them to move floating objects at will." Link to Original Source top
GlowingCat (2459788) writes "The issue of security of the Russian segment of the Internet will be a topic for discussion at the meeting of the Russian Security Council, with the participation of President Vladimir Putin and several high-ranking officials. The meeting will take place next week. According to various reports, the officials will make a number of decisions regulating the use of the Internet in Russia, providing for the ability to cut the Russian Internet, known as Runet, from the outside world, in case of emergency."

GlowingCat (2459788) writes "One of the main problems in attempting to calculate gravitational interactions with gravitons has been that the calculations produced unphysical infinities at almost every step. Bern and colleagues, however, managed to enormously simplify the calculations by showing that, at least in some cases, gravitons can be replaced by two copies of gluons — the carriers of the strong nuclear force. If this double-copy-of-gluons relationship holds in general, this clue could potentially lead to a dramatic breakthrough in the search for a quantum theory of gravity." Link to Original Source top

Menuet has realtime transparency for GUI, which is calculated in the main CPU, so no special compatibility with graphics cards is needed. 0.99.26 inludes also support for SMP and mathematical functions, like FFT." top
Neutrino experiment replicates faster-than-light f
GlowingCat (2459788) writes "Physicists have replicated the finding that the subatomic particles called neutrinos seem to travel faster than light. It is a remarkable confirmation of a stunning result, yet most in the field remain sceptical that the ultimate cosmic speed limit has truly been broken.
The collaboration behind the experiment, called OPERA (Oscillation Project with Emulsion-tracking Apparatus), made headlines in September with its claim that a beam of neutrinos made the 730-kilometre journey from CERN, Europe's particle-physics lab near Geneva in Switzerland, to the Gran Sasso National Laboratory near L'Aquila, Italy, faster than the speed of light. The result defies Albert Einstein’s special theory of relativity, which states that this cannot happen." Link to Original Source
