LIGO is a large-scale physics experiment to detect "ripples in spacetime," as well as gravity waves from outer space. But it turns out that it's also creating gravity waves, according to a team of physicists led by Belinda Pang, a physicist at the California Institute of Technology. sciencehabit quotes Science magazine: Although these waves are far too feeble to detect directly, the researchers say, the radiation in principle could be used to try to detect weird quantum mechanical effects among large objects... Of course, LIGO doesn't generate large gravitational waves -- you could probably make bigger ones yourself by whirling bowling balls around -- but it does so with optimal efficiency [and] the waves could still be used to probe quantum effects among macroscopic objects, Pang says. Quantum mechanics says that a vanishingly small object such as an electron can literally be in two places in once. Many physicists suspect that it might just be possible to coax a macroscopic object, such as one of LIGO's mirrors, into a similar state of quantum motion. That delicate state wouldn't last long, as interactions with the outside world would make it "decohere" and put it in one place or another. However, one could imagine measuring the rate at which such a state decoheres to see whether it matches the rate expected from the radiation of gravitational waves, Pang says. "It's unbelievably difficult," Pang says. "But if you want to do it, what we're saying is that LIGO is the best place to do it."

schwit1 quotes The South China Morning Post: Stanford University students have recreated a Chinese beer using a recipe that dates back 5,000 years. The beer "looked like porridge and tasted sweeter and fruitier than the clear, bitter beers of today," said Li Liu, a professor in Chinese archaeology, was quoted by the university as saying. Last spring, Liu and her team of researchers were carrying out excavation work at the Mijiaya site in Shaanxi province and found two pits containing remnants of pottery used to make beer, including funnels, pots and amphorae. The pits dated to between 3400BC and 2900BC, in the late Yangshao era. They found a yellowish residue on the remains of the items, including traces of yam, lily root and barley...Liu taught her students to recreate the recipe as part of her archaeology course. One student following a second ancient beer recipe created a beverage that "smelled like funky cheese."

More than 650 whales beached themselves in New Zealand, and more than 350 of them died. But now an anonymous reader shares NPR's report about a surprising result for the second group of whales. When volunteer rescuers left the beach for the night Saturday, hundreds of survivors from the second stranding remained ashore. Then something curious happened: When the people returned Sunday morning, almost all the surviving whales were gone. All but 17 had left the beach and returned to the waters of Golden Bay overnight. "We had 240 whales strand yesterday in the afternoon and we were fearful we were going to end up with 240 dead whales this morning," Herb Christophers, a spokesman for New Zealand's Department of Conservation, told Reuters. "But they self-rescued, in other words the tide came in and they were able to float off and swim out to sea."

In 2015 the FBI took over a Tor-accessible child pornography site to infect its users with malware so they could be identified and prosecuted. But now one suspect is challenging that evidence in court, with three different privacy groups filing briefs in his support. An anonymous reader writes. One EFF attorney argues it's a classic case of an unreasonable search, which is prohibited by the U.S. Constitution. "If the FBI tried to get a single warrant to search 8,000 houses, such a request would unquestionably be denied." But there's another problem, since the FBI infected users in 120 different countries. "According to Privacy International, the case also raises important questions: What if a foreign country had carried out a similar hacking operation that affected U.S. citizens?" writes Computerworld. "Would the U.S. welcome this...? The U.S. was overstepping its bounds by conducting an investigation outside its borders without the consent of affected countries, the group said." The FBI's evidence is also being challenged by the ACLU of Massachusetts, and the EFF plans to file two more challenges in March, warning that otherwise "the precedent is likely to impact the digital privacy rights of all Internet users for years to come... Courts need to send a very clear message that vague search warrants that lack the required specifics about who and what is to be searched wonâ(TM)t be upheld."
