(PhysOrg.com) -- Hong Kong physicists say they have proved that a single photon obeys Einstein's theory that nothing can travel faster than the speed of light -- demonstrating that outside science fiction, time travel is impossible. A group of physicists at the Hong Kong University of Scien...
UMass Lowell last polled millennials in the days leading up to the 2016 presidential election and found that nearly a quarter of those surveyed would rather have seen a giant meteor strike the Earth than see either of then-candidates Hilary Clinton or Trump elected president. While that response ...
"Few products are 100% green," the authors conclude. "In most cases, firms must make choices about where to invest to capture the greatest green benefit and the greatest competitive advantage. This study shows that making these investments in central versus non-central features can have a signi...
How many devices have been implanted and how many removed? The lack of data about medical devices is a problem. The government has so far not embraced recommendations for a comprehensive device register, one allowing timely identification of what was implanted and by whom. ...
camera has had no impact at the site at all. So conventional approaches to assessing the impact of cameras on collisions may be overoptimistic. This has clear and obvious implications when considering the cameras' value-for-money and whether the investment could have achieved a better return ...
In the science categories, winners often have to wait decades before the Nobel judges feel confident their discovery has withstood the test of time. It's different for the peace prize, which is often intended as a shot in the arm to someone in the midst of a struggle for peace or democr...
a computer's information without the user knowing. In addition to invading the user's privacy, however, it may slow the system down. "All malware," Johansen says, "take up both system and network resources," so even the least imposing kind will have some effect on a computer's activity...
Experiments with Arabidopsis The two Tübingen researchers have now combined the density andstressfactors in a novelmathematical model. "This showed that under intense stress, it can be advantageous to have many neighbors and that competition only occurs at very high densities," Tielbörger sums up...
Nobel season is upon us. On Monday, the Nobel Prize judges will begin a series of daily announcements revealing this year's winners. To help avoid any embarrassing water-cooler faux pas, here's a true-or-false guide to the prizes created in 1895 by Swedi
" Landry says. "The best way to do that is to conduct experiments that focus on all of the corner cases and can demonstrate that algorithms like these will actually work 99.999 percent of the time."
