Researchers Predict Next-Gen Batteries Will Last 10 Times Longer ( 120

Lithium-metal electrodes could increase the storage capacity of batteries 10-fold, predict researchers at the University of Michigan, allowing electric cars to drive from New York to Denver without recharging. Using a $100 piece of technology, the team is now peeking inside charging batteries to study the formation of "dendrites," which consume liquid electrolytes and reduce capacity. Slashdot reader Eloking quotes New Atlas: Battery cells are normally tested through cycles of charge and discharge, testing the capacity and flow potential of the cells before being dissected. Dasgupta and his team...added a window to a lithium cell so that they could film the dendrites forming and deforming during charge and discharge cycles.
In a video interview they're reporting that dendrites can actually help a battery if they form a small, even "carpet" inside of the battery which "can keep more lithium in play." According to the article, "The future of lithium-ion batteries is limited, says University of Michigan researcher Neil Dasgupta, because the chemistry cannot be pushed much further than it already has. Next-generation lithium cells will likely use lithium air and lithium sulfur chemistries."

"Splat" of Schiaparelli Mars Lander Likely Found ( 67

Long-time Slashdot reader Tablizer quotes Space Flight Now: Views from NASA's Mars Reconnaissance Orbiter released Friday show the crash site where Europe's experimental Schiaparelli lander fell to the red planet's surface from a height of several miles, leaving a distinct dark patch on the Martian landscape...The image from MRO's context camera shows two new features attributed to the Schiaparelli spacecraft, including a large dark scar spanning an estimated 50 feet (15 meters) by 130 feet (40 meters). Schiaparelli's ground team believes it is from the high-speed impact of the lander's main body... A little more than a half-mile (1 kilometer) to the south, a bright spot appears in the image, likely the 39-foot-diameter (12-meter) supersonic parachute and part of Schiaparelli's heat shield, which released from the lander just before ESA lost contact."

A British Supercomputer Can Predict Winter Weather a Year In Advance ( 125

The national weather service of the U.K. claims it can now predict the weather up to a year in advance. An anonymous reader quotes The Stack: The development has been made possible thanks to supercomputer technology granted by the UK Government in 2014. The £97 million high-performance computing facility has allowed researchers to increase the resolution of climate models and to test the retrospective skill of forecasts over a 35-year period starting from 1980... The forecasters claim that new supercomputer-powered techniques have helped them develop a system to accurately predict North Atlantic Oscillation -- the climatic phenomenon which heavily impacts winters in the U.K.
The researchers apparently tested their supercomputer on 36 years worth of data, and reported proudly that they could predict winter weather a year in advance -- with 62% accuracy.

Quantum Researchers Achieve 10-Fold Boost In Superposition Stability ( 75

An anonymous reader quotes The Stack: A team of Australian researchers has developed a qubit offering ten times the stability of existing technologies. The computer scientists claim that the new innovation could significantly increase the reliability of quantum computing calculations... The new technology, developed at the University of New South Wales, has been named a 'dressed' quantum bit as it combines a single atom with an electromagnetic field. This process allows the qubit to remain in a superposition state for ten times longer than has previously been achieved. The researchers argue that this extra time in superposition could boost the performance stability of quantum computing calculations... Previously fragile and short-lived, retaining a state of superposition has been one of the major barriers to the development of quantum computing. The ability to remain in two states simultaneously is the key to scaling and strengthening the technology further.
Do you ever wonder what the world will look like when everyone has their own personal quantum computer?

'Anonymous' Hacker Indicted As His Hunger Strike Continues ( 64

Eight months after being rescued at sea near Cuba and then arrested, Anonymous hacker Martin Gottesfeld now faces prosecution as well as death by hunger. Newsweek reports: A member of Anonymous has been indicted on hacking charges while on the third week of a prison hunger strike protesting perceived institutionalized torture and political prosecutions. Martin Gottesfeld, 32, was charged this week in relation to the hacking of Boston Children's Hospital in 2014 following the alleged mistreatment of one of its patients. Gottesfeld has previously admitted to targeting the hospital, though says he did it in defense of "an innocent, learning-disabled, 15-year-old girl"...

Since beginning his hunger strike on October 3, Gottesfeld tells Newsweek from prison he has lost 16.5 pounds. He says he will continue his hunger strike until two demands are met: a promise from the presidential candidates that children are not mistreated in the way he claims Pelletier was; and an end to the "political" style of prosecution waged by Carmen Ortiz, the U.S. attorney for Massachusetts.

The indictment claims that the hospital spent more than $300,000 to "mitigate" the damage from the 2014 attack.

Russians Seek Answers To Central Moscow GPS Anomaly ( 162

stevegee58 writes: Russians have been noticing that their GPS doesn't work in Moscow near the Kremlin. Everyone from taxi drivers to Pokemon Go players suddenly notice that they're transported 18 miles away at the airport when they near the Kremlin. While this may be an annoyance to the public it seems like a reasonable countermeasure to potential terrorist threats. Is it only a matter of time before other vulnerable sites such as the White House or the Capitol in Washington start doing the same? "A programmer for Russian internet firm Yandex, Grigory Bakunov, said Thursday his research showed a system for blocking GPS was located inside the Kremlin, the heavily guarded official residence of Russian President Vladimir Putin," reports Yahoo. "The first anomaly was recorded in June, according to Russian media reports, which have also suggested that the GPS interference comes and goes in a pattern. Putin's spokesman Dmitry Peskov said Thursday he did not know why the malfunction was occurring and admitted experiencing the problem himself when driving recently. Peskov redirected questions to Russia's Federal Guards Service, which is responsible for protecting the Kremlin and senior Russian officials."

Chemical-Releasing Bike Lock Causes Vomiting To Deter Thieves ( 264

An anonymous reader quotes a report from BBC: The "Skunklock" is a U-shaped steel bicycle lock with a pressurized, stinking gas inside. The gas escapes in a cloud if someone attempts to cut the lock. The company claims its "noxious chemical" is so disgusting it "induces vomit in the majority of cases." Even better, it claims, the gas causes "shortness of breathing" and impaired eyesight. The idea, which tries to make stealing a bike as unpleasant as possible, is raising money for production on crowdfunding site Indiegogo. "Our formula irreversibly ruins the clothes worn by the thief or any of the protection they may be wearing," the company claims on its crowdfunding page. Since stolen bikes sell for a fraction of their true cost, replacing clothing or equipment could make the theft more trouble than it's worth. Skunklock says it has tested its foul gas, and it even penetrates high-end gas masks -- though most thieves are unlikely to go to such lengths. But the company said that the compressed gas is perfectly safe -- and can only be released "by trying to cut through it with an angle grinder." If the chemical countermeasure is released, it is a one-time only use, and the lock, which costs over $100, will have to be replaced. But the hope is that the unpleasant experience will cause them to abandon the attempted theft, leaving the bicycle behind.

Schiaparelli Mars Lander May Have Exploded On Impact, European Agency Says ( 108

Instead of drifting gently onto Mars' surface, the Schiaparelli Mars lander hit the planet hard -- and possibly exploded, the European Space Agency said today. NPR adds: The NASA images, taken on Oct. 20, show two recent changes to the landscape on Mars' surface -- one dark blotch, and one white speck -- which are being interpreted as Schiaparelli's parachute and its crash site. With the warning that analysis is still ongoing, here are the details the ESA is sharing Friday: "Estimates are that Schiaparelli dropped from a height of between 2 and 4 kilometers, therefore impacting at a considerable speed, greater than 300 km/h [186 mph]. The relatively large size of the feature would then arise from disturbed surface material. It is also possible that the lander exploded on impact, as its thruster propellant tanks were likely still full." That sequence of events followed the lander's largely trouble-free approach to the Martian surface, a trip that was being widely watched on Wednesday, when the craft lost contact with the ESA and its Mars mothership, the Trace Gas Orbiter, just before its touchdown.

Stephen Hawking: AI Will Be Either the Best or the Worst Thing To Humanity ( 207

At the opening of the new Leverhulme Centre for the Future of Intelligence (LCFI) at Cambridge University, Stephen Hawking offered his insight into the positive and negative implications of creating a true AI. He said, via BetaNews:We spend a great deal of time studying history, which, let's face it, is mostly the history of stupidity. So it's a welcome change that people are studying instead the future of intelligence. The potential benefits of creating intelligence are huge... With the tools of this new technological revolution, we will be able to undo some of the damage done to the natural world by the last one -- industrialization. And surely we will aim to fully eradicate disease and poverty. Every aspect of our lives will be transformed. In short, success in creating AI, could be the biggest event in the history of our civilization. But it could also be the last, unless we learn how to avoid the risks. Alongside the benefits, AI will also bring dangers, like powerful autonomous weapons, or new ways for the few to oppress the many. It will bring great disruption to our economy. AI will be either the best, or the worst thing ever to happen to humanity. We do not yet know which.

Facebook Bans Animated Breast Cancer Awareness Video Showing Circle-Shaped Breasts ( 97

Last month, Facebook deleted a historic Vietnam war photo of a naked girl fleeing a napalm attack, claiming it violated Facebook's restrictions on nudity. Now it appears that the company has removed a video on breast cancer awareness posted in Sweden after deeming the images offensive, the Swedish Cancer Society said on Thursday. The Guardian reports: The video, displaying animated figures of women with circle-shaped breasts, was aimed at explaining to women how to check for suspicious lumps. Sweden's Cancerfonden said it had tried in vain to contact Facebook, and had decided to appeal against the decision to remove the video. "We find it incomprehensible and strange how one can perceive medical information as offensive," Cancerfoden communications director Lena Biornstad told Agence France-Presse. "This is information that saves lives, which is important for us," she said. "This prevents us from doing so." The Guardian went on to report in a separate article that the the Swedish Cancer Society decided to make the round breasts square to evade Facebook's censorship of female anatomy. The group issued an open letter to Facebook featuring the pair of pair of breasts constructed of pink squares as opposed to pink circles. Facebook did apologize for banning the video, saying in a statement to the Guardian: "We're very sorry, our team processes millions of advertising images each week, and in some instances we incorrectly prohibit ads. This image does not violate our ad policies. We apologize for the error and have let the advertiser know we are approving their ads."

Nurses In Australia Face Punishment For Promoting Anti-Vaccination Messages Via Social Media ( 596 writes: Medical Express reports that nurses and midwives promoting anti-vaccination messages in Australia could face punishment including being slapped with a caution and having their ability to practice medicine restricted. Serious cases could be referred to an industry tribunal, where practitioners could face harsher penalties such as having their registration suspended or cancelled. The Nursing and Midwifery Board of Australia released the vaccination standards in response to what it described as a small number of nurses and midwives promoting anti-vaccination via social media. The statement also urges members of the public to report nurses or midwives promoting anti-vaccination. Promoting false, misleading or deceptive information is an offense under national law and is prosecutable by the Australian Health Practitioner Regulation Agency. "The board will consider whether the nurse or midwife has breached their professional obligations and will treat these matters seriously," the statement said. However Dr. Hannah Dahlen, a professor of midwifery at the University of Western Sydney and the spokeswoman for the Australian College of Midwives, worries the crackdown may push people with anti-vaccination views further underground. "The worry is the confirmation bias that can occur, because people might say: 'There you go, this is proof that you can't even have an alternative opinion.' It might in fact just give people more fuel for their belief systems."

Amazon CEO Jeff Bezos Thinks Space Can Be the New Internet ( 90

Speaking at the Vanity Fair New Establishment Summit in San Francisco today, Amazon CEO Jeff Bezos said space is essentially a new internet, as it is the next frontier that needs new infrastructure to support new entrepreneurs. He said the purpose of Blue Origin is to build out a similar kind of infrastructure for space that Amazon used to operate during the days of the early internet, such as the United States Postal Service and long distance phone network. The Verge reports: "Two kids in their dorm room can reinvent an industry," Bezos said, referring to the strengths of the modern internet. "Two kids in their dorm room cannot do anything interesting in space." Bezos says rocket reusability needs to be improved, and both Blue Origin and Elon Musk's SpaceX are working toward the goal of vastly reducing the cost of sending payloads to space. Bezos said there's also a number of restraints right now that prevent the kind of entrepreneurial spirit that helped create Amazon do the same for a next-generation space venture. "We need to be able to put big things in space at low cost." Bezos talked of his earliest days at Amazon more than 20 years ago, where he was driving packages himself to the post office with a 10-person team. "We were sitting on a bunch of a heavy lifting infrastructure," he said. "For example, there was already a gigantic network called United States Postal Service. The internet itself was sitting on time of the long distance phone network." This is the kind of infrastructure Bezos hopes to build out with Blue Origin. "Every time you figure out some way of providing tools and services that allow other people to deploy their creativity, you're really onto something," Bezos said. But building that infrastructure space is still the grandest dream. "I think space is about to enter a golden age."

First New US Nuclear Reactor In 20 Years Goes Live ( 336

An anonymous reader quotes a report from CNN: The Tennessee Valley Authority is celebrating an event 43 years in the making: the completion of the Watts Bar Nuclear Plant. In 1973, the TVA, one of the nation's largest public power providers, began building two reactors that combined promised to generate enough power to light up 1.3 million homes. The first reactor, delayed by design flaws, eventually went live in 1996. Now, after billions of dollars in budget overruns, the second reactor has finally started sending power to homes and businesses. Standing in front of both reactors Wednesday, TVA President Bill Johnson said Watts Bar 2, the first U.S. reactor to enter commercial operation in 20 years, would offer clean, cheap and reliable energy to residents of several southern states for at least another generation. Before Watts Bar 2, the last time an American reactor had fired up was in 1996. It was Watts Bar 1 -- and according to the Atlanta Journal-Constitution, it cost $6.8 billion, far greater than the original price tag at $370 million. In the 2000s, some American power companies, faced with growing environmental regulations, eyed nuclear power again as a top alternative to fossil fuels such as coal and oil. A handful of companies, taking advantage of federal loan guarantees from the Bush administration, revived nuclear reactor proposals in a period now known as the so-called "nuclear renaissance." Eventually, nuclear regulators started to green light new reactors, including ones in Georgia and South Carolina. In 2007, the TVA resumed construction on Watts Bar 2, according to the International Atomic Energy Agency. The TVA originally said it would take five years to complete. The TVA, which today serves seven different southern states, relies on nuclear power to light up approximately 4.5 million homes. Watts Bar 2, the company's seventh operating reactor, reaffirms its commitment to nukes for at least four more decades, Johnson said Wednesday. In the end, TVA required more than five years to build the project. The final cost, far exceeding its initial budget, stood at $4.7 billion.

Schiaparelli Mars Probe's Parachute 'Jettisoned Too Early', Whereabouts Still Unknown ( 184

An anonymous reader writes: Europe's Schiaparelli lander did not behave as expected as it headed down to the surface of Mars on Wednesday. Telemetry data recovered from the probe during its descent indicates that its parachute was jettisoned too early. The rockets it was supposed to use to bring itself to a standstill just above the ground also appeared to fire for too short a time. The European Space Agency (Esa) has not yet conceded that the lander crashed but the mood is not positive. Experts will continue to analyse the data and they may also try to call out to Schiaparelli in the blind hope that it is actually sitting on the Red Planet intact. In addition, the Americans will use one of their satellites at Mars to image the targeted landing zone to see if they can detect any hardware. Although, the chances are slim because the probe is small. For the moment, all Esa has to work with is the relatively large volume of engineering data Schiaparelli managed to transmit back to the "mothership" that dropped it off at Mars - the Trace Gas Orbiter.

Stanford Researchers Release Virtual-Reality Simulation That Transports Users To Ocean of the Future ( 83

Tekla Perry writes: Stanford's Jeremy Bailenson and his Virtual Human Interaction Lab have for more than a decade been testing whether experiences from virtual reality can change real-world behavior. Now they are using their knowledge -- and expertise at developing VR software -- in what they hope will be a large-scale move towards making people behave better. The lab this week released, for free, a VR experience for the HTC Vive. It's aimed at giving people the sense of diving down to a coral reef -- but the real goal is getting them to consider how carbon dioxide released into the atmosphere is killing the oceans. He hopes, with the dearth of good VR content available, this software will proliferate at least as fast as VR hardware does. Next up for the lab, a deep dive into homelessness. The experience is formally called "The Ocean Acidification Experience" and it's "intended to teach users about the chemistry behind ocean acidification, as well as the problems it causes, and what they can do to help prevent it," according to IEEE Spectrum. Bailenson describes the general story line by saying, "It starts with a globe. We talk about how we can see climate on the coastlines, but nobody can see how carbon dioxide affects the oceans. We then take you into a crowded city. You touch an exhaust pipe, and you then see carbon dioxide go into the atmosphere, and you're told to follow one particular molecule. Then you are in a boat, on the ocean, you see your molecule come towards you. You touch it and push it into the water; when it lands you see the chemical reaction that creates acid; that's the chemistry lesson. Then you are underwater, at this special reef in Ischia, Italy. This reef has naturally occurring carbon dioxide from underwater volcanoes; it shows how all our oceans will look by 2100. We take you to a normal reef, where you see coral, and count sea snails and species of fish. Then you go to an acidified reef; you see that algae have taken over the reef, there is no coral; there are fewer fish species, and no sea snails. The final scene tells you what you can do to help, prevent this future, including managing your own carbon footprint, talking to decision makers, and supporting research organizations."
