+ - Saturn's F Ring Is Now Three Times As Wide As During The Voyager Flybys

Submitted by KentuckyFC
KentuckyFC (1144503) writes "In 1980 and 1981, Voyager 1 and 2 flew past Saturn providing unprecedented images of its magnificent ring system. At that time, its most distant discrete ring, the F ring, was about 200 kilometres wide. But puzzlingly, images sent back by Cassini show that the ring is now 580 kilometres wide and twice as bright as it was thirty years ago. Now astronomers think they have finally solved the mystery of the expanding F ring. The ring is shepherded by a number of small moons, the most famous of which is Prometheus. These moons interact gravitationally with the ring creating structures such as braids and spokes. The new thinking is that the moons' orbits resonate with the F ring, pushing clouds of dust and ice further away from Saturn. This makes the ring wider. But beyond a certain radius the orbit of the dust becomes unstable and it begins to spiral back towards Saturn and collides with the rest of the ring. This causes a chain reaction of collisions that dramatically increases the number of particles in the ring and hence its brightness. This theory also leads to a prediction--the resonant process is currently at a maximum but should reduce sharply in the coming years, if the theory is correct. So by 2018, the F ring should be back to the same configuration the Voyagers saw in 80/81."

Following the link, found a number of articles about academies formation policies, but nothing obviously titled about creationism. Furthermore, a quick search at the bbc news site did not reveal any stories about banning creationism yet in British science curriculum. Perhaps, the author should provide more specific links as evidence of his claims.

sciencehabit (1205606) writes "It’s a nagging thorn in the side of climatologists: Even though the world is warming, the average area of the sea ice around Antarctica is increasing. Climate models haven’t explained this seeming contradiction to anyone’s satisfaction—and climate change deniers tout that failure early and often. But a new paper suggests a possible explanation: Variability in the heights of ocean waves pounding into the sea ice may help control its advance and retreat."

Submitted by Anonymous Coward
An anonymous reader writes "The US Air Force’s 10th Flight Test Squadron recently took delivery of the first B-52H Stratofortress to complete a refit through the Combat Network Communications Technology (CONECT) program. It's an effort to bring the Cold War era heavy bomber into the 21st century way of warfare—or at least up to the 1990s, technology-wise. While the aircraft received piecemeal upgrades over the past 50 years of flying, CONECT is the first major information technology overhaul for the Air Force’s B-52H fleet since the airplanes started entering service in 1961."

+ - Amazon: malignant monopoly, or just plain evil?->

Submitted by Anonymous Coward
An anonymous reader writes "Sci-fi author Charles Stross has a post providing insight into Amazon's recent bullying tactics against a major book publishing group. He puts the fight into perspective for the two most important parts of the book market: author and reader. He says: 'Amazon's strategy (as I noted in 2012) is to squat on the distribution channel, artificially subsidize the price of ebooks ("dumping" or predatory pricing) to get consumers hooked, rely on DRM on the walled garden of the Kindle store to lock consumers onto their platform, and then to use their monopsony buying power to grab the publishers' share of the profits. If you're a consumer, in the short term this is good news: it means you get cheap books. But if you're a reader, you probably like to read new books. By driving down the unit revenue, Amazon makes it really hard for publishers—who are a proxy for authors—to turn a profit. Eventually they go out of business, leaving just Amazon as a monopoly distribution channel retailing the output of an atomized cloud of highly vulnerable self-employed piece-workers like myself. At which point the screws can be tightened indefinitely. And after a while, there will be no more Charlie Stross novels because I will be unable to earn a living and will have to go find a paying job. TL:DR; Amazon's strategy against Hachette is that of a bullying combine the size of WalMart leaning on a much smaller supplier. And the smaller supplier in turn relies on really small suppliers like me. It's anti-author, and in the long term it will deprive you of the books you want to read.'"

The previously closed hotel at 1825 Collins Avenue is the latest project for Sixty Hotels, a hotel management company that also has venues in Los Angeles and New York. The new owners of The Nautilus, Insite Group and Quadrum have invested the $61 million purchase price in what seems to be a flourishing accommodation environment for the tourist industry. The new Nautilus is a modern day hotel that gives a nod to the original building which was designed by Morris Lapidus."

An anonymous reader writes "MIT Technology Review reports that French company Sigfox will soon roll out a cellular data network in the San Francisco Bay Area aimed exclusively for low-bandwidth, low power devices such as household appliances and sensors. It's the U.S. debut for a technology already in use in France. The network uses the 900 MHz unlicensed spectrum used by cordless phones. Sigfox says that and their technology's very low bandwidth makes it possible to connect devices significantly more cheaply than with conventional cellular modems and service."

+ - The Folly of the Chinese Hacking Indictments

Submitted by Trailrunner7
Trailrunner7 (1100399) writes "It was high drama. Indicting five Chinese military officers for allegedly hacking into the networks of several old-line American companies and stealing financial data, technical specifications, internal communications and other sensitive information was an unprecedented step in what has been a long-running war of words between American and Chinese politicians and diplomats. The Obama administration has accused the Chinese military of running regular operations to compromise the networks of American businesses and steal as much intellectual property as they can. The Chinese, of course, deny this, and counter that the U.S. is in fact the one targeting Chinese businesses and government agencies. The rhetoric has reached the highest levels in recent months, with President Obama talking about the problem of cyberespionage with Chinese President Xi Jinping in September.

Let’s be honest; the chances of any of these men ever setting foot in the U.S. to face these charges are roughly zero point zero. The Chinese government has virtually no incentive whatsoever to cooperate with the U.S. on this issue. Relations between the two governments are not, shall we say, ideal, and putting five PLA officers on FBI most wanted posters is not likely to help in that regard.

Nor does the U.S. hold the moral high ground here. As the Snowden revelations of the last year have shown, the NSA and the U.S. government have turned the Internet into a turnkey surveillance platform, bending the global network to its will and its purpose. The latest evidence of this also surfaced Monday, with The Intercept revealing that the NSA was recording all of the cell phone traffic in the Bahamas and another, unnamed country. The U.S. also has long accused the Chinese IT company Huawei of being a pawn of the government, and has warned American companies about buying gear from the company, for fear it may be compromised during manufacture. As it turns out, the NSA allegedly has been conducting just such operations on IT gear manufactured by U.S. companies, intercepting shipments and implanting “beacons” that give the agency access to the boxes after installation.

It’s difficult to take a tough stance on things like this, when there’s an army of skeletons banging on the door of your own closet."
