A glitch in American Airlines' pilot scheduling system means that thousands of flights during the holiday season currently do not have pilots assigned to fly them. From a report: The shortage was caused by an error in the system pilots use to bid for time off, the Allied Pilots Association told NPR. The union represents the airline's 15,000 pilots. "The airline is a 24/7 op," union spokesman Dennis Tajer told CNBC. "The system went from responsibly scheduling everybody to becoming Santa Claus to everyone." "The computer said, 'Hey ya'll. You want the days off? You got it.'"

Mark Wilson writes: A group going by the name Google You Owe Us is taking Google to court in the UK, complaining that the company harvested personal data from 5.4 million iPhone users. The group is led by Richard Lloyd, director of consumer group Which?, and it alleges that Google bypassed privacy settings on iPhones between June 2011 and February 2012. The lawsuit seeks compensation for those affected by what is described as a "violation of trust." Google is accused of breaching UK data protection laws, and Lloyd says that this is "one of the biggest fights of my life." Even if the case is successful, the people represented by Google You Owe Us are not expected to receive more than a few hundred pounds each, and this is not an amount that would make much of an impact on Google's coffers.

An anonymous reader quotes a report from Engadget: Nasdaq is planning to launch contracts for bitcoin futures in the first half of 2018, according to The Wall Street Journal, which will enable investors to predict and put money on the future price of the currency. The Wall Street Journal also reports that broker Cantor Fitzgerald will be launching bitcoin derivatives on its own exchange in the first half of next year as well, making for yet another brokerage to help make bitcoin a more mainstream financial instrument. The relative youth and volatility of the currency still keeps many investors away, of course, but bitcoin is probably here to stay, even if this is just a bubble. New uses for regular folks to spend with the currency continue to rise, like the UK Visa card based on bitcoin and Square's testing of the currency in its payment app.

Science_afficionado writes: Are you a cat lover? A dog lover? If so, you may be interested in the first scientific study to actually count the number of cortical neurons in the brains of a number of carnivores, including cats and dogs. Bottom line: Dogs have about twice as many of these "little grey cells" as cats. These "little gray cells" are associated with thinking, planning and complex behavior. The study found that dogs have about 530 million cortical neurons while cats have about 250 million. (For comparison, the human brain has 16 billion.) Another interesting discovery was that carnivores have about the same ratio of neurons to brain size as that of herbivores, "suggesting that there is just as much evolutionary pressure on the herbivores to develop the brain power to escape from predators as there is on carnivores to catch them," reports Vanderbilt University. "The study's findings also challenge the prevailing view that domesticated animals have smaller brains than their wild cousins. The ratios of brain size to body weight of the domestic species they analyzed -- ferret, cat and dog -- did not scale in a significantly different manner from those of their wild relatives -- mongoose, raccoon, hyena, lion and brown bear."

The results of the study are described in a paper titled "Dogs have the most neurons, though not the largest brain: Trade-off between body mass and number of neurons in the cerebral cortex of large carnivoran species" accepted for publication in the open access journal Frontiers in Neuroanatomy.

Kekke writes: Lots of buzz around this. Russian cosmonaut Anton Shkaplerov took routine samples from the outside of the International Space Station during a spacewalk. These samples were analyzed and found to contain bacteria that must have come from somewhere other than Earth or the ISS itself. "Bacteria that had not been there during the launch of the ISS module were found on the swabs," Mr. Shkaplerov told TASS Russian News Agency. "So they have flown from somewhere in space and settled on the outside hull." He made it clear that "it seems, there is no danger," and that scientists are doing more work to find out what they are. The Independent writes, "Finding bacteria that came from somewhere other than Earth would be one of the biggest breakthroughs in the history of science -- but much more must be done before such a claim is made."

An anonymous reader quotes a report from CNNMoney: The McKinsey Global Institute cautions that as many as 375 million workers will need to switch occupational categories by 2030 due to automation. The work most at risk of automation includes physical jobs in predictable environments, such as operating machinery or preparing fast food. Data collection and processing is also in the crosshairs, with implications for mortgage origination, paralegals, accounts and back-office processing. To remain viable, workers must embrace retraining in different fields. But governments and companies will need to help smooth what could be a rocky transition.

Despite the looming challenges, the report revealed how workers can move forward. While the introduction of the personal computer in the 1980s eliminated some jobs, it created many more roles. Workers who are willing to develop new skills should be able to find new jobs. The authors don't expect automation will displace jobs involving managing people, social interactions or applying expertise. Gardeners, plumbers, child and elder-care workers are among those facing less risk from automation. The report says that 39 million to 73 million jobs in the U.S. could be destroyed, but about 20 million of those displaced workers can be shifted fairly easily into similar occupations. Globally, up to 800 million workers could be displaced.

schwit1 shares a report from Popular Science: University of Buffalo biologist Charlotte Lindqvist and her international team in Pakistan and Singapore provided the first strong evidence that presumed yetis are actually bears. They published their results in the Proceedings of the Royal Society B on Tuesday. Icon Film secured nine samples that purported to be genuine yeti artifacts, and Lindqvist gathered 15 samples from known bear populations. By sequencing mitochondria from all these sources, she and her fellow researchers were able to determine that all but one of the yeti artifacts actually came from local bears. That last sample was from a dog. They also figured out that Himalayan brown bears split off from the rest of the regional bear population several thousand years ago, which is why they're so genetically distinct from most other brown bears. Living in geographic isolation for so long has separated them from other Asian brown bears, and even from their relatives on the nearby Tibetan plateau. They even look different. But prior to Lindqvist's work, it wasn't clear just how long Himalayan bears had been on their own. Researchers will need higher-quality samples to figure out the whole picture, but even this small step is major for a species that's hardly been studied.

Two teams of researchers have published papers [1, 2] in the journal Nature detailing how they were able to create unprecedented quantum simulators consisting of over 50 qubits. The University of Maryland team and National Institute of Standards and Technology team -- the two teams behind one of the two new papers -- were able to create a quantum simulator with 53 qubits. Motherboard reports: Quantum simulators are a special type of quantum computer that uses qubits to simulate complex interactions between particles. Qubits are the informational medium of quantum computers, analogous to a bit in an ordinary computer. Yet rather than existing as a 1 or 0, as is the case in a conventional bit, a qubit can exist in some superposition of both of these states at the same time. For the Maryland experiment, each of the qubits was a laser cooled ytterbium ion. Each ion had the same electrical charge, so they repelled one another when placed in close proximity. The system created by Monroe and his colleagues used an electric field to force the repelled ions into neat rows. At this point, lasers are used to manipulate all the ytterbium qubits into the same initial state. Then another set of lasers is used to manipulate the qubits so that they act like atomic magnets, where each ion has a north and south pole. The qubits either orient themselves with their neighboring ions to form a ferromagnet, where their magnetic fields are aligned, or at random. By changing the strength of the laser beams that are manipulating the qubits, the researchers are able to program them to a desired state (in terms of magnetic alignment).

According to Zhexuan Gong, a physicist at the University of Maryland, the 53 qubits can be used to simulate over a quadrillion different magnetic configurations of the qubits, a number that doubles with each additional qubit added to the array. As these types of quantum simulators keep adding more qubits into the mix, they will be able to simulate ever more complex atomic interactions that are far beyond the capabilities of conventional supercomputers and usher in a new era of physics research. Another team from Harvard and Maryland also released a paper today in which it demonstrated a quantum simulator using 51 qubits.

Nearly a year after the case was initially filed, Coinbase has been ordered to turn over identifying records for all users who have bought, sold, sent, or received more than $20,000 through their accounts in a single year. The digital asset broker estimates that 14,355 users meet the government's requirements. The Verge reports: For each account, the company has been asked to provide the IRS with the user's name, birth date, address, and taxpayer ID, along with records of all account activity and any associated account statements. The result is both a definitive link to the user's identity and a comprehensive record of everything they've done with their Coinbase account, including other accounts to which they've sent money. The order is significantly narrower than the IRS's initial request, which asked for records on every single Coinbase user over the same period. That request would also have required all communications between Coinbase and the user, a measure the judge ultimately found unnecessarily comprehensive. The government made no claim of suspicion against individual users, but instead argued that the order was justified based on the discrepancy between Coinbase users and U.S. citizens reporting Bitcoin gains to the IRS.

An anonymous reader quotes a report from Quartz: Snap announced today (Nov. 29), that it was rolling out a redesign for Snapchat that's intended to separate users' feeds between their friends from the brands that publish content on the app. Founder and CEO Evan Spiegel published an op-ed in Axios this morning about the direction that social media has taken over the last few years, where content from brands and influencers has been given the same weight and placement as content from friends and loved ones in users' feeds. Spiegel also took to YouTube, for the second time in about two years, to explain how the new Snapchat works.

The new structure seems like a positive move. It's sort of solidifying the app, which turned down $3 billion from Facebook in 2013, as the "anti-Facebook." Facebook has muddled the line between content, news about friends, and pure internet garbage to the point where it's become nearly impossible for the average user to know what's important, or even true -- on purpose. Snapchat is reaffirming the value of staying connected to your friends, and enjoying news and entertainment content, but showing that the two activities should not be the same thing. Whether this restructuring will convince more people to start using Snapchat, however, is unclear.

Tesla's Model 3 has a confirmed range of 310 miles, according to the Environmental Protection Agency. "That figure applies to the long-range version of the Model 3, and echoes the vehicle specs released by Tesla back in July," reports The Verge. "It also makes the Model 3 one of the most efficient passenger electric vehicles on the market." From the report: The EPA's range is used as the advertised figure for electric vehicles that are sold in the US. The 310-mile range is an estimate of the number of miles the vehicle should be able to travel in combined city and highway driving from a full charge. That's 131 miles per gallon gasoline equivalent (MPGe) for city driving, 120 MPGe on the highway, and 126 MPGe combined. You'll have to pay more to get that extended range, though. Tesla said it would be selling a standard version of the Model 3, with just 220 miles of range, for $35,000. The long-range version will start at $44,000, the automaker says. Production on the standard version isn't expected to begin until 2018.

Armand Winter shares a report from ZDNet: Microsoft president Brad Smith said the company will spend $150 million in transport infrastructure, public spaces, sports fields and green space. It expects the project will create 2,500 construction and development jobs. Microsoft's renovation budget is modest compared with the $5 billion Apple spent on its new spaceship headquarters in Cupertino, while Microsoft's Washington neighbor and cloud rival, Amazon, will spend $5 billion on a second North American headquarters, which will offer space for 50,000 people. "We are not only creating a world-class work environment to help retain and attract the best and brightest global talent, but also building a campus that our neighbors can enjoy, and that we can build in a fiscally smart way with low environmental impact," said Smith in a blog post.

An anonymous reader quotes a report from CNET: Whether you love to add a little sparkle to your skin, or you think glitter truly is the herpes of the craft world (once it's on you, it never comes off), some scientists are now claiming that glitter is a hazard to the environment. Glitter, along with microbeads, are considered to fall under the category of microplastics, which are defined as plastics which are less than five millimeters in length. Microbeads are often found in facial scrubs, toothpaste, soaps, cosmetics and more. These microbeads pass through water filtration systems after usage but don't disintegrate, and often end up being consumed by marine life, causing concern among scientists keeping a close eye on how pollution effects fish.

"I think all glitter should be banned, because it's microplastic," Dr. Trisia Farrelly of New Zealand's Massey University told the Independent. Historically, glitter was made from mica rock particles, glass and even crushed beetles. Modern-day crafting glitter is made primarily from metals, while fine-milled cosmetic glitter is made from polyester, foil and plastics.

Windows 10 has found its way onto 600 million active devices, says CEO Satya Nadella. From a report: CEO Satya Nadella referenced the new number for the first time moments ago at the company's annual shareholders meeting. The number is up from the 500 million devices touted by Microsoft earlier this year, but it's still well short of the company's original goal of 1 billion Windows 10 devices within two to three years of its 2015 release.

Fearful of missing out on the frenzy in the Bitcoin world, several people were left disappointed on Wednesday noon after they were unable to buy some cryptocurrency because the websites of Coinbase and Gemini, two of the largest online exchanges for Bitcoin trading in the United States, were either down or taking too long to load, they said. In a statement, Coinbase said it was facing issues handling the overwhelming traffic it has been receiving on its website. Bitcoin surged past $11,000, the highest it has ever been, early Wednesday, though it has since taken a tumble as well, going as low as $9,290.30. Gemini said in a tweet it had resolved the performance issues, though some users continue to report delays on the website. Bitcoin's professional trading platform GDAX and exchanges Kraken and Bitstamp were also facing issues on Wednesday. The issues had been addressed, they said.
