cylonlover writes: Many of the current experimental "invisibility cloaks" are based around the same idea — light coming from behind an object is curved around it and then continues on forward to a viewer. That person is in turn only able to see what's behind the object, and not the object itself. Scientists from Germany's Karlsruhe Institute of Technology have applied that same principle to sound waves, and created what could perhaps be described as a "silence cloak."

Quantum theorem shakes foundations The wavefunction is a real physical object after all, say researchers.
"... the new paper, by a trio of physicists led by Matthew Pusey at Imperial College London, presents a theorem showing that if a quantum wavefunction were purely a statistical tool, then even quantum states that are unconnected across space and time would be able to communicate with each other. As that seems very unlikely to be true, the researchers conclude that the wavefunction must be physically real after all.
David Wallace, a philosopher of physics at the University of Oxford, UK, says that the theorem is the most important result in the foundations of quantum mechanics that he has seen in his 15-year professional career. “This strips away obscurity and shows you can’t have an interpretation of a quantum state as probabilistic,” he says.

'The complaint focuses on ICM's recently concluded "sunrise" period, during which porn companies, for about $200, could apply to own a.xxx address matching their trademark or.com domain.' Schools also felt the same way, and had to reserve domains under their name so that no porn content could be put up on them. The.xxx TLD has also previously been subject to criticism by both religious groups and adult industry, but for different reasons. Religious groups believe the.xxx TLD legitimases pornography, while adult industry believes it could lead to censorship.

The experiment, located at Gran Sasso in Italy, saw neutrinos arrive 90 nanoseconds early from their starting point at CERN in Switzerland. Others have doubted OPERA's claim, but in a new paper, the group reaffirms its commitment to the measurement. “It’s slightly better than the previous result,” OPERA’s physics coordinator Dario Autiero told Nature News. Most members of the collaboration didn't sign up to the original paper out of skepticism have now come on board. But scientists outside the group still aren't sure. "Independent checks are the way to go", says Rob Plunkett, co-spokesman a rival experiment called MINOS."
Frans Faase writes: "Beter measurements by the OPERA experiments confirm earlier findings of faster than light neutrino's and have been published in an update version of Measurement of the neutrino velocity with the OPERA detector in the CNGS beam. One uncertainty about the earlier OPERA measurements, which relied on the shape of the pulse of the neutrino's being shot, has been eliminated. But this does not exclude the possibility of other systematic errors in the method of measurement."

Music Canada, EMI Music Canada, and Universal Music Canada — settled
the largest copyright
class action lawsuit
in Canadian history by agreeing to pay over $50 million to compensate
for hundreds of thousands of infringing uses of sound recordings. While
the record labels did not admit liability, the massive settlement spoke
for itself. While the Canadian case has now settled, Universal Music
own lawsuit, this time against its insurer, who it expects to pay
costs of the settlement.
