An invisible layer of scum on the sea surface can reduce carbon dioxide exchange between the atmosphere and the oceans by up to 50%, scientists have discovered. From a report: Researchers from Heriot-Watt, Newcastle and Exeter universities say the findings, published in the journal Nature Geoscience on Monday, have major implications for predicting our future climate. The world's oceans absorb around a quarter of all man-made carbon dioxide emissions, making them the largest long-term sink of carbon on Earth. Greater sea turbulence increases gas exchange between the atmosphere and oceans and until now it was difficult to calculate the effect of "biological surfactants." Teams from the Natural Environment Research Council, the Leverhulme Trust and the European Space Agency developed a system that compares "the surfactant effect" between different seawaters in real time. They found surfactants can reduce carbon dioxide exchange by up to 50%.

An anonymous reader quotes a report from The Guardian: Birds had to rediscover flight after the meteor strike that killed off the dinosaurs, scientists say. The cataclysm 66 million years ago not only wiped out Tyrannosaurus rex and ground-dwelling dinosaur species, but also flying birds, a detailed survey of the fossil record suggests. As forests burned around the world, the only birds to survive were flightless emu-like species that lived on the ground. The six to nine-mile-wide meteor struck the Earth off the coast of Mexico, releasing a million times more energy than the largest atomic bomb. Hot debris raining from the sky is thought to have triggered global wildfires immediately after the impact. It took hundreds or even thousands of years for the world's forests of palms and pines to recover. Fossil records from New Zealand, Japan, Europe and North America, all show evidence of mass deforestation. They also reveal that birds surviving the end of the Cretaceous period had long sturdy legs made for living on the ground. They resembled emus and kiwis, said the researchers whose findings are reported in the journal Current Biology.

A court case in California alleges that Facebook used its apps to gather information about users and their friends, including some who had not signed up to the social network, reading their text messages, tracking their locations and accessing photos on their phones. The Guardian reports: The claims of what would amount to mass surveillance are part of a lawsuit brought against the company by the former startup Six4Three, listed in legal documents filed at the superior court in San Mateo as part of a court case that has been ongoing for more than two years. The allegations about surveillance appear in a January filing, the fifth amended complaint made by Six4Three. It alleges that Facebook used a range of methods, some adapted to the different phones that users carried, to collect information it could use for commercial purposes.

"Facebook continued to explore and implement ways to track users' location, to track and read their texts, to access and record their microphones on their phones, to track and monitor their usage of competitive apps on their phones, and to track and monitor their calls," one court document says. But all details about the mass surveillance scheme have been redacted on Facebook's request in Six4Three's most recent filings. Facebook claims these are confidential business matters. It has until next Tuesday to submit a claim to the court for the documents to remain sealed from public view.

Astronomers have spotted an asteroid orbiting our sun in the opposite (retrograde) direction to the planets. The 2-mile-wide asteroid, known as 2015 BZ509, is the first "interstellar immigrant" from beyond our solar system to remain, according to the study published in the journal Monthly Notices of the Royal Astronomical Society. The Guardian reports: Further work on the asteroid revealed it takes the same length of time to orbit the sun as the planet Jupiter at a similar average distance, although in the opposite direction and with a different shaped path, suggesting the two have gravitational interactions. But unpicking quite where the asteroid came from was challenging. Asteroids that orbit the sun on paths that take them between the giant planets -- Jupiter, Saturn, Uranus and Neptune -- are known as centaurs, and it is thought that many might come from distant bands of material within the solar system such as the scattered disk or the Oort cloud. Several, like BZ509, are known to have retrograde paths, although how they ended up on such orbits is unclear.

But there was a clue there was something unusual about BZ509: while previous studies suggested retrograde centaurs stay gravitationally "tied" to planets for 10,000 years at most, recent work had suggested this asteroid's orbit had been linked to Jupiter for far longer, probably as a result of the planet's mass and the way both take the same time to orbit the sun. The discovery provides vital clues as to the asteroid's origins. [Dr Fathi Namouni from the Observatory de la Cote d'Azur said] that the model suggests the most likely explanation is that the asteroid was captured by Jupiter as it hurtled through the solar system from interstellar space. "It means it is an alien to the solar system," he said.

An assessment of all life on Earth has revealed humanity's surprisingly tiny part in it as well as our disproportionate impact. From a report: The world's 7.6 billion people represent just 0.01% of all living things, according to the study. Yet since the dawn of civilisation, humanity has caused the loss of 83% of all wild mammals and half of plants, while livestock kept by humans abounds. The new work is the first comprehensive estimate of the weight of every class of living creature and overturns some long-held assumptions. Bacteria are indeed a major life form -- 13% of everything -- but plants overshadow everything, representing 82% of all living matter. All other creatures, from insects to fungi, to fish and animals, make up just 5% of the world's biomass.

Another surprise is that the teeming life revealed in the oceans by the recent BBC television series Blue Planet II turns out to represent just 1% of all biomass. The vast majority of life is land-based and a large chunk -- an eighth -- is bacteria buried deep below the surface. "I was shocked to find there wasn't already a comprehensive, holistic estimate of all the different components of biomass," said Prof Ron Milo, at the Weizmann Institute of Science in Israel, who led the work, published in the Proceedings of the National Academy of Sciences.

The vast majority of emails flooding inboxes across Europe from companies asking for consent to keep recipients on their mailing list are unnecessary and some may be illegal, privacy experts have said, as new rules over data privacy come into force at the end of this week. From a report: Many companies, acting based on poor legal advice, a fear of fines of up to $23.5 million and a lack of good examples to follow, have taken what they see as the safest option for hewing to the General Data Protection Regulation (GDPR): asking customers to renew their consent for marketing communications and data processing. But Toni Vitale, the head of regulation, data and information at the law firm Winckworth Sherwood, said many of those requests would be needless paperwork, and some that were not would be illegal.

Google is being sued in the high court for as much as $4.3 billion for the alleged "clandestine tracking and collation" of personal information from 4.4 million iPhone users in the UK. From a report: The collective action is being led by former Which? director Richard Lloyd over claims Google bypassed the privacy settings of Apple's Safari browser on iPhones between August 2011 and February 2012 in order to divide people into categories for advertisers. At the opening of an expected two-day hearing in London on Monday, lawyers for Lloyd's campaign group Google You Owe Us told the court information collected by Google included race, physical and mental heath, political leanings, sexuality, social class, financial, shopping habits and location data.

Hugh Tomlinson QC, representing Lloyd, said information was then "aggregated" and users were put into groups such as "football lovers" or "current affairs enthusiasts" for the targeting of advertising. Tomlinson said the data was gathered through "clandestine tracking and collation" of browsing on the iPhone, known as the "Safari Workaround" -- an activity he said was exposed by a PhD researcher in 2012. Tomlinson said Google has already paid $39.5m to settle claims in the US relating to the practice. Google was fined $22.5m for the practice by the US Federal Trade Commission in 2012 and forced to pay $17m to 37 US states.

An anonymous reader quotes a report from The Guardian: Amazon has threatened to move jobs out of its hometown of Seattle after the city council introduced a new tax to try to address the homelessness crisis. The world's second-biggest company has warned that the "hostile" tax, which will charge firms $275 per worker a year to fund homelessness outreach services and affordable housing, "forces us to question our growth here."

Amazon, which is Seattle's biggest private sector employer with more than 40,000 staff in the city, had halted construction work on a 17-storey office tower in protest against the tax. Pressure from Amazon and other big employers, including Starbucks and Expedia, had forced councillors to reduce the tax from an initial proposal of $500 per worker. The tax will only effect companies making revenue of more than $20 million-a-year. The tax is expected to raise between $45 million and $49 million a year, of which about $10 million would come from Amazon. The company said it would restart building work on the tower but may sublease another new office block to reduce its tax bill.

Citing reports from The Guardian and Focus Ecuador, The Verge reports that Ecuador's intelligence program spent at least $5 million "on an elaborate security and surveillance network around WikiLeaks founder Julian Assange." The intelligence program was known as "Operator Hotel," which began as "Operation Guest" when Assange took refuge in Ecuador's UK embassy in 2012. From the report: Operation Hotel has allegedly covered expenses like installing CCTV cameras and hiring a security team to "secretly film and monitor all activity in the embassy," including Assange's daily activities, moods, and interactions with staff and visitors. The Guardian estimates Ecuadorian intelligence agency Senain has spent at least $5 million on Assange-related operations, based on documents they reviewed. The report details attempts to improve Assange's public image and potentially smuggle him out of the embassy if he was threatened. But it also writes that relations between Assange and Ecuador have badly deteriorated over the past several years. In 2014, Assange allegedly breached the embassy's network security, reading confidential diplomatic material and setting up his own secret communications network.

A NASA probe that explored Jupiter's moon Europa flew through a giant plume of water vapour that erupted from the icy surface and reached a hundred miles high, according to a fresh analysis of the spacecraft's data. An anonymous reader shares a The Guardian report: The discovery has cemented the view among some scientists that the Jovian moon, one of four first spotted by the Italian astronomer Galileo Galilei in 1610, is the most promising place in the solar system to hunt for alien life. If such geysers are common on Europa, NASA and European Space Agency (ESA) missions that are already in the pipeline could fly through and look for signs of life in the brine, which comes from a vast subsurface ocean containing twice as much water as all the oceans on Earth.

NASA's Galileo spacecraft spent eight years in orbit around Jupiter and made its closest pass over Europa, a moon about the size of our own, on 16 December 1997. As the probe dropped beneath an altitude of 250 miles, its sensors twitched with unexpected signals that scientists were unable to explain at the time. Now, in a new study, the researchers describe how they went back to the Galileo data after grainy images beamed home from the Hubble space telescope in 2016 showed what appeared to be plumes of water blasting from Europa's surface.

Scientists will grow small amounts of tissue, known as brain organoids, from human stem cells that have been edited to contain "Neanderthalized" versions of several genes. "The lentil-sized organoids, which are incapable of thoughts or feelings, replicate some of the basic structures of an adult brain," reports The Guardian. "They could demonstrate for the first time if there were meaningful differences between human and Neanderthal brain biology." From the report: The latest work focuses on differences in three genes known to be crucial for brain development. Using the editing technique Crispr, changes have been introduced into human stem cells to make them closer to Neanderthal versions. The stem cells are coaxed using chemical triggers to become neurons, which spontaneously clump together and self-organize into miniature brain-like structures that grow to a few millimeters in diameter. The lack of any sensory input means the internal wiring is haphazard and varies from one blob to the next. The scientists will compare the Neanderthalized organoids and the fully human ones to assess the speed at which the stem cells divide, develop and organize into three-dimensional brain structures and whether the brain cells wire up differently. The work won't reveal which species is "smarter," but could hint at differences in the ability to plan, socialize and use language.

Long-time Slashdot reader skegg writes: Last night was federal budget night in Australia, and one of the announcements means Australians will face a crackdown on cash-in-hand payments in an attempt by the government to reduce money laundering and tax evasion. The government has turned its attention to the "black economy" in an attempt to raise billions of extra dollars and intends to limit cash payments for purchase goods and services to $10,000.
The financial services minister argues that currently the status quo "gives some businesses an unfair competitive advantage."

Social media platforms are using the same techniques as gambling firms to create psychological dependencies and ingrain their products in the lives of their users, experts warn. From a report: These methods are so effective they can activate similar mechanisms as cocaine in the brain, create psychological cravings and even invoke "phantom calls and notifications" where users sense the buzz of a smartphone, even when it isn't really there. "Facebook, Twitter and other companies use methods similar to the gambling industry to keep users on their sites," said Natasha Schull, the author of Addiction by Design, which reported how slot machines and other systems are designed to lock users into a cycle of addiction. "In the online economy, revenue is a function of continuous consumer attention -- which is measured in clicks and time spent."

An anonymous reader quotes a report from Ars Technica: A British police agency is defending its use of facial recognition technology at the June 2017 Champions League soccer final in Cardiff, Wales -- among several other instances -- saying that despite the system having a 92-percent false positive rate, "no one" has ever been arrested due to such an error. New data about the South Wales Police's use of the technology obtained by Wired UK and The Guardian through a public records request shows that of the 2,470 alerts from the facial recognition system, 2,297 were false positives. In other words, nine out of 10 times, the system erroneously flagged someone as being suspicious or worthy of arrest.

In a public statement, the SWP said that it has arrested "over 450" people as a result of its facial recognition efforts over the last nine months. "Of course, no facial recognition system is 100 percent accurate under all conditions. Technical issues are normal to all face recognition systems, which means false positives will continue to be a common problem for the foreseeable future," the police wrote. "However, since we introduced the facial recognition technology, no individual has been arrested where a false positive alert has led to an intervention and no members of the public have complained." The agency added that it is "very cognizant of concerns about privacy, and we have built in checks and balances into our methodology to make sure our approach is justified and balanced."

An academic paper on global climate zones written by three Australians more than a decade ago has been named the most cited source on Wikipedia, having being referenced more than 2.8m times. From a report: The authors of the paper, who are still good friends, had no idea about the wider impact of their work until recently. The paper, published in 2007 in the journal Hydrology and Earth System Sciences, used contemporary data to update a widely used model for classifying the world's climates. Known as the Koppen Climate Classification System, the model was first published by climatologist Wladimir Koppen in 1884, but it had not been comprehensively updated for decades.

The lead author of the paper is Dr Murray Peel, a senior lecturer in the department of infrastructure engineering at the University of Melbourne, and he co-authored the updated climate map with geography professor Brian Finlayson and engineering professor Thomas McMahon, both now retired. "We are amazed, absolutely amazed at the number of citations," Finlayson told Guardian Australia from his home in Melbourne. "We are not so much amazed at the fact it's been cited as we are about the number of people who have cited it."

umafuckit writes: The Guardian reports on Aventus, an open-source protocol designed to eliminate fraud and touting for large events. The Aventus Protocol "would allow event organizers to give each ticket a unique identity that is tied to its owner. Since each ticket is a linked list of records, where each new one contains an encrypted version of the previous one, they cannot be faked. The software also allows event promoters to keep an easy record of who owns the ticket, which means they can control the prices. The protocol was launched at Imperial College London last week and will be trialed at this year's world cup, where it will handle 10,000 ticket sales.

An anonymous reader shares an excerpt from an article via The Guardian, written by David Graeber: One day, the wall shelves in my office collapsed. This left books scattered all over the floor and a jagged, half-dislocated metal frame that once held the shelves in place dangling over my desk. I'm a professor of anthropology at a university. A carpenter appeared an hour later to inspect the damage, and announced gravely that, as there were books all over the floor, safety rules prevented him from entering the room or taking further action. I would have to stack the books and not touch anything else, whereupon he would return at the earliest available opportunity. The carpenter never reappeared. Each day, someone in the anthropology department would call, often multiple times, to ask about the fate of the carpenter, who always turned out to have something extremely pressing to do. By the time a week was out, it had become apparent that there was one man employed by buildings and grounds whose entire job it was to apologize for the fact that the carpenter hadn't come. He seemed a nice man. Still, it's hard to imagine he was particularly happy with his work life.

Everyone is familiar with the sort of jobs that don't seem, to the outsider, really to do much of anything: HR consultants, communications coordinators, PR researchers, financial strategists, corporate lawyers or the sort of people who spend their time staffing committees that discuss the problem of unnecessary committees. What if these jobs really are useless, and those who hold them are actually aware of it? Could there be anything more demoralizing than having to wake up in the morning five out of seven days of one's adult life to perform a task that one believes does not need to be performed, is simply a waste of time or resources, or even makes the world worse? There are plenty of surveys about whether people are happy at work, but what about whether people feel their jobs have any good reason to exist? I decided to investigate this phenomenon by drawing on more than 250 testimonies from people around the world who felt they once had, or now have, what I call a bullshit job. Graeber defines a "bullshit job" as "one so completely pointless that even the person who has to perform it every day cannot convince themselves there's a good reason for them to be doing it." Do you feel that your work is completely unnecessary?

An amateur mathematician has made the first breakthrough in more than 60 years towards solving a well-known maths problem. From a report: Aubrey de Grey, who is more widely known as a maverick biologist intent on extending the human lifespan, has taken the academic world by surprise after announcing a new solution to the so-called Hadwiger-Nelson problem. The problem sounds deceptively simple, but despite some professionals spending years trying to crack it, progress has stalled since shortly after the puzzle was first posed in 1950. "Literally, this is the first progress in more than 60 years," said Gil Kalai, a mathematician at Hebrew University of Jerusalem.

The problem is as follows. Imagine a collection of dots connected by lines. The dots can be arranged any way at all, the only rule is that all the connecting lines must be of equal length. For instance, in a square the diagonal would not be joined up, but the outer edges would be. Now, colour in all the dots so that no two connected points have the same colour. How many colours are required. For a square, the answer would be two. But the Hadwiger-Nelson problem asks what the minimum would be for any configuration -- even one that extends across a plane of infinite size.

"The gambling industry is increasingly using artificial intelligence to predict consumer habits and personalize promotions to keep gamblers hooked," reports The Guardian, citing industry insiders. "Current and former gambling industry employees have described how people's betting habits are scrutinized and modeled to manipulate their future behavior." From the report: Publicly, gambling executives boast of increasingly sophisticated advertising keeping people betting, while privately conceding that some are more susceptible to gambling addiction when bombarded with these type of bespoke ads and incentives. Gamblers' every click, page view and transaction is scientifically examined so that ads statistically more likely to work can be pushed through Google, Facebook and other platforms. Users unwittingly consent to the use of their data in ways they aren't aware of due to lengthy terms and conditions, enabling their information to legally be used in this way. Last August, the Guardian revealed the gambling industry uses third-party companies to harvest people's data, helping bookmakers and online casinos target people on low incomes and those who have stopped gambling. Despite condemnation from MPs, experts and campaigners, such practices remain an industry norm.

Long-time Slashdot reader Martin S. pointed us to this an excerpt from the new book Live Work Work Work Die: A Journey into the Savage Heart of Silicon Valley by Portland-based investigator reporter Corey Pein.

The author shares what he realized at a job recruitment fair seeking Java Legends, Python Badasses, Hadoop Heroes, "and other gratingly childish classifications describing various programming specialities." I wasn't the only one bluffing my way through the tech scene. Everyone was doing it, even the much-sought-after engineering talent. I was struck by how many developers were, like myself, not really programmers, but rather this, that and the other. A great number of tech ninjas were not exactly black belts when it came to the actual onerous work of computer programming. So many of the complex, discrete tasks involved in the creation of a website or an app had been automated that it was no longer necessary to possess knowledge of software mechanics. The coder's work was rarely a craft. The apps ran on an assembly line, built with "open-source", off-the-shelf components. The most important computer commands for the ninja to master were copy and paste...

[M]any programmers who had "made it" in Silicon Valley were scrambling to promote themselves from coder to "founder". There wasn't necessarily more money to be had running a startup, and the increase in status was marginal unless one's startup attracted major investment and the right kind of press coverage. It's because the programmers knew that their own ladder to prosperity was on fire and disintegrating fast. They knew that well-paid programming jobs would also soon turn to smoke and ash, as the proliferation of learn-to-code courses around the world lowered the market value of their skills, and as advances in artificial intelligence allowed for computers to take over more of the mundane work of producing software. The programmers also knew that the fastest way to win that promotion to founder was to find some new domain that hadn't yet been automated. Every tech industry campaign designed to spur investment in the Next Big Thing -- at that time, it was the "sharing economy" -- concealed a larger programme for the transformation of society, always in a direction that favoured the investor and executive classes.
"I wasn't just changing careers and jumping on the 'learn to code' bandwagon," he writes at one point. "I was being steadily indoctrinated in a specious ideology."

The New York Times reports on rocks in the country of Oman that react naturally with carbon dioxide, turning it into stone. Scientists say that if this natural process, called carbon mineralization, could be harnessed, accelerated and applied inexpensively on a huge scale -- admittedly some very big "ifs" -- it could help fight climate change. Rocks could remove some of the billions of tons of heat-trapping carbon dioxide that humans have pumped into the air since the beginning of the Industrial Age. And by turning that CO2 into stone, the rocks in Oman -- or in a number of other places around the world that have similar geological formations -- would ensure that the gas stayed out of the atmosphere forever...

Capturing and storing carbon dioxide, is drawing increased interest. The Intergovernmental Panel on Climate Change says that deploying such technology is essential to efforts to rein in global warming... At a geothermal power plant in Iceland, after several years of experimentation, an energy company is injecting modest amounts of carbon dioxide into volcanic rock, where it becomes mineralized. Dutch researchers have suggested spreading a kind of crushed rock along coastlines to capture CO2. And scientists in Canada and South Africa are studying ways to use mine wastes, called tailings, to do the same thing.
Meanwhile, the Guardian reports an alternate perspective from 86-year-old social scientist Mayer Hillman: "We're doomed." He's predicting the end of most life on the planet, citing the lack of any way to reverse the process that's already melting the polar ice caps.

"Optimism about the future is wishful thinking, says Hillman. He believes that accepting that our civilization is doomed could make humanity rather like an individual who recognizes he is terminally ill. Such people rarely go on a disastrous binge; instead, they do all they can to prolong their lives."

A 39-year-old motorist pointed his Tesla S60 down a highway at 40 mph -- while sitting in its passenger seat, leaning back with his hands behind his head. Another motorist spotted the empty driver's seat and filmed the car. Now (nearly a year later) the Tesla's owner "has been banned from driving for 18 months," the Guardian reports. The driver, from Nottingham, pleaded guilty to one count of dangerous driving after admitting he switched seats when he turned on the car's autopilot mode, leaving the car's brakes and steering wheel unmanned. The driver admitted that the stunt in May last year had been silly, but insisted that he was simply "the unlucky one who got caught" trying out the "amazing" feature on the car.

As well as the 18-month driving ban he was ordered to carry out 100 hours of unpaid work. He was also put on a 10-day rehabilitation programme and will have to pay £1,800 in costs.
A police officer called the behavior "reckless," adding that autopilot controls like the ones on Teslas "are in no way a substitute for a competent motorist in the driving seat who can react appropriately to the road ahead."

An anonymous reader quotes a report from The Guardian: The European Union will ban the world's most widely used insecticides from all fields due to the serious danger they pose to bees. The ban on neonicotinoids, approved by member nations on Friday, is expected to come into force by the end of 2018 and will mean they can only be used in closed greenhouses.

Bees and other insects are vital for global food production as they pollinate three-quarters of all crops. The plummeting numbers of pollinators in recent years has been blamed, in part, on the widespread use of pesticides. The EU banned the use of neonicotinoids on flowering crops that attract bees, such as oil seed rape, in 2013. fBut in February, a major report from the European Union's scientific risk assessors (Efsa) concluded that the high risk to both honeybees and wild bees resulted from any outdoor use, because the pesticides contaminate soil and water. This leads to the pesticides appearing in wildflowers or succeeding crops. A recent study of honey samples revealed global contamination by neonicotinoids. The ban on the three main neonicotinoids has widespread public support, with almost 5 million people signing a petition from campaign group Avaaz.

Leading scientists have drawn up plans for a vast multinational European institute devoted to world-class artificial intelligence (AI) research in a desperate bid to nurture and retain top talent in Europe. From a report: The new institute would be set up for similar reasons as Cern, the particle physics lab near Geneva, which was created after the second world war to rebuild European physics and reverse the brain drain of the brightest and best scientists to the US. Named the European Lab for Learning and Intelligent Systems, or Ellis, the proposed AI institute would have major centres in a handful of countries, the UK included, with each employing hundreds of computer engineers, mathematicians and other scientists with the express aim of keeping Europe at the forefront of AI research. In an open letter that urges governments to act, the scientists describe how Europe has not kept up with the US and China, where the vast majority of leading AI firms and universities are based. The letter adds that while a few "research hotspots" still exist in Europe, "virtually all of the top people in those places are continuously being pursued for recruitment by US companies."

An anonymous reader quotes a report from The Guardian: The cow could be left as the biggest land mammal on Earth in a few centuries, according to a new study that examines the extinction of large mammals as humans spread around the world. The spread of hominims -- early humans and related species such as Neanderthals -- from Africa thousands of years ago coincided with the extinction of megafauna such as the mammoth, the sabre-toothed tiger and the glyptodon, an armadillo-like creature the size of a car. "There is a very clear pattern of size-biased extinction that follows the migration of hominims out of Africa," the study's lead author, Felisa Smith, of the University of New Mexico, said of the study published in the journal Science on Thursday. Humans apparently targeted big species for meat, while smaller creatures such as rodents escaped, according the report, which examined trends over 125,000 years. In North America, for instance, the mean body mass of land-based mammals has shrunk to 7.6kg (17lb) from 98kg after humans arrived. If the trend continues "the largest mammal on Earth in a few hundred years may well be a domestic cow at about 900kg", the researchers wrote. That would mean the loss of elephants, giraffes and hippos. In March, the world's last male northern white rhino died in Kenya.

shilly writes: British finance expert Martin Lewis is suing Facebook for defamation, after a year of trying to persuade the company to stop accepting scam ads featuring his name and image. Facebook insists that he report to them every time he spots a scam; he wants them to check with him before they take money for an ad featuring his name or picture, so he can tell them if it's legit or not. "Lewis said he would not profit from any damages won, which he would donate to charities combating fraud, but that he hoped the action would prompt the site to stamp out scam adverts," reports The Guardian.

An anonymous reader quotes a report from Gizmodo: A British teenager who gained notoriety for hacking a number of high profile United States government employees including former CIA director John Brennan and former director of intelligence James Clapper was sentenced Friday to two years in prison. Eighteen-year-old Kane Gamble pleaded guilty to 10 separate charges, including eight counts of "performing a function with intent to secure unauthorized access" and two counts of "unauthorized modification of computer material," the Guardian reported.

Gamble, otherwise known by his online alias Cracka, was 15 at the time that he started his hacking campaigns. The alleged leader of a hacking group known as Crackas With Attitude (CWA), Gamble made it a point to target members of the U.S. government. The young hacker's group managed to successfully gain access to ex-CIA director John Brennan's AOL email account. The group hacked a number of accounts belonging to former Director of National Intelligence James Clapper, including his personal email, his wife's email, and his phone and internet provider account. The hackers allegedly made it so every call to Clapper's home phone would get forwarded to the Free Palestine Movement.

An anonymous reader quotes a report from The Daily Beast: Companies across the nation are now using some rudimentary artificial intelligence, or AI, systems to screen out applicants before interviews commence and for the interviews themselves. As a Guardian article from March explained, many of these companies are having people interview in front of a camera that is connected to AI that analyzes their facial expressions, their voice and more. One of the top recruiting companies doing this, Hirevue, has large customers like Hilton and Unilever. Their AI scores people using thousands of data points and compares it to the scores of the best current employees. But that can be unintentionally problematic. As Recode pointed out, because most programmers are white men, these AI are actually often trained using white male faces and male voices. That can lead to misperceptions of black faces or female voices, which can lead to the AI making negative judgments about those people. The results could trend sexist or racist, but the employer who is using this AI would be able to shift the blame to a supposedly neutral technology. Companies are also having people do their first interview with an AI chatbot. "One popular AI that does this is called Mya, which promises a 70 percent decrease in hiring time," reports The Daily Beast. "Any number of questions these chatbots could ask could be proxies for race, gender or other factors."

Experts in the industry say that current advances in artificial intelligence and automation could replace as many as half the nation's financial services workers over the next decade, though it will take a big investment to make that happen. The Mercury News reports: "Unless banks deal with the performance issues that AI will cause for ultra-large databases, they will not be able to take the money gained by eliminating positions and spend it on the new services and products they will need in order to stay competitive," James D'Arezzo, CEO of Glendale-based Condusiv Technologies, said. Intensive hardware upgrades are often cited as an answer to the problem, but D'Arezzo said that's prohibitively expensive.

Speaking to an audience last year in Frankfurt, Germany, Deutsche Bank CEO John Cryan predicted a "bonfire" of industry jobs as automation moves forward. "In our bank we have people doing work like robots," he said. "Tomorrow we will have robots behaving like people. It doesn't matter if we as a bank will participate in these changes or not, it is going to happen." Increased processing power, cloud storage and other developments are making many tasks possible that once were considered too complex for automation, according to Cryan. D'Arezzo, whose company works to improve existing software performance, said the financial industry is being swamped by "a tsunami of data," including new compliance requirements for customer privacy and constantly changing bank regulations. Bhagwan Chowdhry, a professor of finance and economics at the UCLA Anderson School of Management, offers a less bleak view of the future. "Technology will eliminate some jobs that are repetitive and require less human judgment," he said, "But I think they will get replaced by other jobs that humans are better at. Anything that requires judgment is something humans will continue to do. We are not good at multiplying 16-digit numbers, but we're good at judging people and detecting if someone is telling the truth."

Facebook said in a blog post yesterday that they tracked users and non-users across websites and apps for three main reasons: providing services directly, securing the company's own site, and "improving our products and services." The statement comes as the company faces a U.S. lawsuit over a controversial facial recognition feature launched in 2011. The Guardian reports: "When you visit a site or app that uses our services, we receive information even if you're logged out or don't have a Facebook account. This is because other apps and sites don't know who is using Facebook," Facebook's product management director, David Baser, wrote. "Whether it's information from apps and websites, or information you share with other people on Facebook, we want to put you in control -- and be transparent about what information Facebook has and how it is used."

But the company's transparency has still not extended to telling non-users what it knows about them -- an issue Zuckerberg also faced questions over from Congress. Asked by Texas representative Gene Green whether all information Facebook holds about a user is in the file the company offers as part of its "download your data" feature, Zuckerberg had responded he believed that to be the case. Privacy campaigner Paul-Olivier Dehaye disagreed, noting that, even as a Facebook user, he had been unable to access personal data collected through the company's off-site tracking systems. Following an official subject access request under EU law, he told MPs last month, Facebook had responded that it was unable to provide the information.

Diamonds found in a meteorite that exploded over the Nubian desert in Sudan a decade ago were formed deep inside a "lost planet" that once circled the sun in the early solar system, scientists say. From a report: Microscopic analyses of the meteorite's tiny diamonds revealed they contain compounds that are produced under intense pressure, suggesting the diamonds formed far beneath the surface of a planet. In this case, the mysterious world was calculated to be somewhere between Mercury and Mars in size. Astronomers have long hypothesised that dozens of fledgling planets, ranging in size from the moon to Mars, formed in the first 10m years of the solar system and were broken apart and repackaged in violent collisions that ultimately created the terrestrial planets that orbit the sun today.

Scientists have created a mutant enzyme that breaks down plastic drinks bottles -- by accident. The breakthrough could help solve the global plastic pollution crisis by enabling for the first time the full recycling of bottles. From a report: The new research was spurred by the discovery in 2016 of the first bacterium that had naturally evolved to eat plastic, at a waste dump in Japan. Scientists have now revealed the detailed structure of the crucial enzyme produced by the bug. The international team then tweaked the enzyme to see how it had evolved, but tests showed they had inadvertently made the molecule even better at breaking down the PET (polyethylene terephthalate) plastic used for soft drink bottles. "What actually turned out was we improved the enzyme, which was a bit of a shock," said Prof John McGeehan, at the University of Portsmouth, UK, who led the research. "It's great and a real finding." The mutant enzyme takes a few days to start breaking down the plastic -- far faster than the centuries it takes in the oceans. But the researchers are optimistic this can be speeded up even further and become a viable large-scale process.

Carbon dioxide from ships at sea will be regulated for the first time following a historic agreement reached after two weeks of detailed talks in London. From a report: Shipping companies will halve their greenhouse gas emissions by 2050 under the plan, brokered by the International Maritime Organization and binding across its 170 member states. The agreement will require a revolution among ships, which are overwhelmingly fuelled by heavy oils at present. In future, they will have to not only be more energy-efficient, but also make use of cleaner energy, in the form of batteries supplying electricity, solar and wind electricity generation, and perhaps even a return to sail in some cases, or more controversially to nuclear power, as some warships already use.

Environmental campaigners said the plan was not enough given the urgency of tackling climate change, though they welcomed the deal, which has taken decades of work. Greenhouse gas emissions from shipping and aviation were omitted from the 1997 Kyoto protocol and have been excluded from regulations on carbon ever since, even though shipping is used for 80% of global trade. Although shipping accounts for only about 2% of global carbon emissions, it has been a cause of particular concern, both because of the increased need for transport under the globalising economy and because many ships use dirty, carbon-rich fuels such as heavy diesel, which would be banned in many countries from onshore transport.

joshtops writes: Instant messaging platform Telegram, which is used by more than 200 million users, has had an open secret since its inception: The platform has served as a haven for online pirates. The Outline reports that the platform is riddled with thousands of groups and channels, many with more than 100,000 members, whose sole purpose of existence is to share illegally copied movies, music albums, apps, and other content. The files are stored directly to Telegram's servers, allowing users to download movies, songs, and other content with one click. Channel admins told The Outline that they have not come across any resistance from Telegram despite the company, along with Apple and Google, maintaining a 'zero tolerance' stance on copyright infringement. This permissiveness on Telegram's part has led to the proliferation of a cottage industry of piracy marketplaces on the service.

[...] The Outline also discovered several groups and channels on Telegram in which stolen credentials -- i.e., the username and password for a website -- from Netflix, Spotify, Hulu, HBO, CBS, EA Sports, Lynda, Sling, WWE Network, Mega, India's Hotstar, and dozens of other services were being offered to tens of thousands of members each day. The Outline sourced nearly three-dozen free credentials from six Telegram channels, all of which worked as advertised. The report says that content creators have reached out to Apple, requesting the iPhone-maker to intervene, but the company has largely ignored the issue.

In an unrelated development, a Moscow court cleared the way on Friday for the local government to ban Telegram, the messaging app, over its failure to give Russian security services the ability to read users' encrypted messages.

A 1.2-mile stretch of road with electric rails has been installed in Stockholm, Sweden, allowing electric vehicles to charge up their batteries as they drive across it. "The technology behind the electrification of the road linking Stockholm Arlanda airport to a logistics site outside the capital city aims to solve the thorny problems of keeping electric vehicles charged, and the manufacture of their batteries affordable," reports The Guardian. From the report: Energy is transferred from two tracks of rail in the road via a movable arm attached to the bottom of a vehicle. The design is not dissimilar to that of a Scalextric track, although should the vehicle overtake, the arm is automatically disconnected. The electrified road is divided into 50m sections, with an individual section powered only when a vehicle is above it. When a vehicle stops, the current is disconnected. The system is able to calculate the vehicle's energy consumption, which enables electricity costs to be debited per vehicle and user. The "dynamic charging" -- as opposed to the use of roadside charging posts -- means the vehicle's batteries can be smaller, along with their manufacturing costs. A former diesel-fuelled truck owned by the logistics firm, PostNord, is the first to use the road.

According to Twitter's latest transparency report, the social media company removed more than 270,000 accounts around the world for promoting terrorism in the second half of 2017. The number of accounts permanently suspended for sharing what the firm called extremist content between July and December represents a drop for the second period in a row. The Guardian reports: The social network puts this down to "years of hard work making our site an undesirable place for those seeking to promote terrorism." Nick Pickles, Twitter UK's head of public policy, said: "The overwhelming majority of these accounts were detected by our own technology, with just 0.2% of the accounts we suspended in 2017 being flagged by the police." Almost 75% of accounts were suspended before they sent their first tweet, according to the report, and 93% were discovered by tools that Twitter engineers had built. Twitter is understood to also use a combination of US and EU lists of terrorist organizations as well as research from academics and experts to identify terrorists on its network. The number of reports of abusive behavior submitted by government representatives also dropped amid a marked change in the type of abusive behavior reported. Two-thirds of the 10,000 reports concerned violated rules over impersonation, with only 16% of the reports for harassment and 12% for hateful conduct. Harassment and hateful conduct each accounted for a third of reported accounts in the first half of 2017. Only a quarter of reports of abusive behavior submitted by government representatives were acted upon by Twitter, compared with 98% of reports relating to the "promotion of terrorism."

An anonymous reader writes: "Comcast, AT&T and Verizon pose a greater surveillance risk than Facebook -- but their surveillance is much harder to avoid," writes Salome Viljoen in an opinion piece for The Guardian. From the report: "Facebook isn't the only company that amasses troves of data about people and leaves it vulnerable to exploitation and misuse. As of last year, Congress extended the same data-gathering practices of tech companies like Google and Facebook to internet providers like Comcast, AT&T and Verizon. Because service providers serve as gatekeepers to the entire internet, they can collect far more information about us, and leave us with far less power to opt out of that process. This means that the risks of allowing our internet providers to collect and monetize the same type of user data that Facebook collects -- and the potential that such data will therefore be misused -- are much, much worse. Your internet provider doesn't just know what you do on Facebook -- it sees all the sites you visit and how much time you spend there. Your provider can see where you shop, what you watch on TV, where you choose to eat dinner, what medical symptoms you search, where you apply for work, school, a mortgage. Everything that is unencrypted is fair game. But internet providers don't just pose a greater surveillance risk than Facebook -- their surveillance is also far harder to avoid. 'Choosing' not to use an internet provider to avoid surveillance is not really a choice at all. As of 2016, only about half of Americans have more than one option for broadband internet. In rural areas, this number drops to just 13%.

Researchers have created a wearable device that can read people's minds when they use an internal voice, allowing them to control devices and ask queries without speaking. From a report: The device, called AlterEgo, can transcribe words that wearers verbalise internally but do not say out loud, using electrodes attached to the skin. "Our idea was: could we have a computing platform that's more internal, that melds human and machine in some ways and that feels like an internal extension of our own cognition?" said Arnav Kapur, who led the development of the system at MIT's Media Lab.

Kapur describes the headset as an "intelligence-augmentation" or IA device, and was presented at the Association for Computing Machinery's Intelligent User Interface conference in Tokyo. It is worn around the jaw and chin, clipped over the top of the ear to hold it in place. Four electrodes under the white plastic device make contact with the skin and pick up the subtle neuromuscular signals that are triggered when a person verbalises internally. When someone says words inside their head, artificial intelligence within the device can match particular signals to particular words, feeding them into a computer.

The Electronic Frontier Foundation's Peter Eckersley writes: Yesterday, The New York Times reported that there is widespread unrest amongst Google's employees about the company's work on a U.S. military project called "Project Maven." Google has claimed that its work on Maven is for "non-offensive uses only," but it seems that the company is building computer vision systems to flag objects and people seen by military drones for human review. This may in some cases lead to subsequent targeting by missile strikes. EFF has been mulling the ethical implications of such contracts, and we have some advice for Google and other tech companies that are considering building military AI systems.
The EFF lists several "starting points" any company, or any worker, considering whether to work with the military on a project with potentially dangerous or risk AI applications should be asking:

1. Is it possible to create strong and binding international institutions or agreements that define acceptable military uses and limitations in the use of AI? While this is not an easy task, the current lack of such structures is troubling. There are serious and potentially destabilizing impacts from deploying AI in any military setting not clearly governed by settled rules of war. The use of AI in potential target identification processes is one clear category of uses that must be governed by law.
2.Is there a robust process for studying and mitigating the safety and geopolitical stability problems that could result from the deployment of military AI? Does this process apply before work commences, along the development pathway and after deployment? Could it incorporate the sufficient expertise to address subtle and complex technical problems? And would those leading the process have sufficient independence and authority to ensure that it can check companies' and military agencies' decisions?
3.Are the contracting agencies willing to commit to not using AI for autonomous offensive weapons? Or to ensuring that any defensive autonomous systems are carefully engineered to avoid risks of accidental harm or conflict escalation? Are present testing and formal verification methods adequate for that task?
4.Can there be transparent, accountable oversight from an independently constituted ethics board or similar entity with both the power to veto aspects of the program and the power to bring public transparency to issues where necessary or appropriate? For example, while Alphabet's AI-focused subsidiary DeepMind has committed to independent ethics review, we are not aware of similar commitments from Google itself. Given this letter, we are concerned that the internal transparency, review, and discussion of Project Maven inside Google was inadequate. Any project review process must be transparent, informed, and independent. While it remains difficult to ensure that that is the case, without such independent oversight, a project runs real risk of harm.

An anonymous reader shares a report: Humans continue to produce new neurons in a part of their brain involved in learning, memory and emotion throughout adulthood, scientists have revealed, countering previous theories that production stopped after adolescence. The findings could help in developing treatments for neurological conditions such as dementia. Many new neurons are produced in the hippocampus in babies, but it has been a matter of hot debate whether this continues into adulthood -- and if so, whether this rate drops with age as seen in mice and nonhuman primates. Although some research had found new neurons in the hippocampus of older humans, a recent study scotched the idea, claiming that new neurons in the hippocampus were at undetectable levels by our late teens.

An anonymous reader quotes a report from The Guardian: It is hard to argue that you cannot trust the government when the government isn't really all that bad. This is the problem facing the small but growing number of Swedes anxious about their country's rush to embrace a cash-free society. Most consumers already say they manage without cash altogether, while shops and cafes increasingly refuse to accept notes and coins because of the costs and risk involved. Until recently, however, it has been hard for critics to find a hearing. "The Swedish government is a rather nice one, we have been lucky enough to have mostly nice ones for the past 100 years," says Christian Engstrom, a former MEP for the Pirate Party and an early opponent of the cashless economy. "In other countries there is much more awareness that you cannot trust the government all the time. In Sweden it is hard to get people mobilized."

There are signs this might be changing. In February, the head of Sweden's central bank warned that Sweden could soon face a situation where all payments were controlled by private sector banks. The Riksbank governor, Stefan Ingves, called for new legislation to secure public control over the payments system, arguing that being able to make and receive payments is a "collective good" like defense, the courts, or public statistics. "Most citizens would feel uncomfortable to surrender these social functions to private companies," he said. "It should be obvious that Sweden's preparedness would be weakened if, in a serious crisis or war, we had not decided in advance how households and companies would pay for fuel, supplies and other necessities." The report mentions a recently-released opinion poll, which found that seven out of 10 Swedes wanted to keep the option to use cash, while just 25% wanted a completely cashless society.

In a rare op-ed, Richard Stallman, the president of the Free Software Foundation, says that the surveillance imposed on us today is worse than in the Soviet Union. He argues that we need laws to stop this data being collected in the first place. From his op-ed: The surveillance imposed on us today far exceeds that of the Soviet Union. For freedom and democracy's sake, we need to eliminate most of it. There are so many ways to use data to hurt people that the only safe database is the one that was never collected. Thus, instead of the EU's approach of mainly regulating how personal data may be used (in its General Data Protection Regulation or GDPR), I propose a law to stop systems from collecting personal data.

The robust way to do that, the way that can't be set aside at the whim of a government, is to require systems to be built so as not to collect data about a person. The basic principle is that a system must be designed not to collect certain data, if its basic function can be carried out without that data. Data about who travels where is particularly sensitive, because it is an ideal basis for repressing any chosen target.

Today marks the 50th anniversary of the original release of Stanley Kubrick's "2001: A Space Odyssey," a seminal film in motion picture history and one that has awed millions over the years. Kubrick's title has often been credited with paving the way for science-fiction films that took a realistic approach to depicting the future. Even as "2001" has grown to become one of the most iconic movies of all time, the reception it received when it originally premiered wasn't good. An excerpt: The film's previews were an unmitigated disaster. Its story line encompassed an exceptional temporal sweep, starting with the initial contact between pre-human ape-men and an omnipotent alien civilization and then vaulting forward to later encounters between Homo sapiens and the elusive aliens, represented throughout by the film's iconic metallic-black monolith. Although featuring visual effects of unprecedented realism and power, Kubrick's panoramic journey into space and time made few concessions to viewer understanding. The film was essentially a nonverbal experience. Its first words came only a good half-hour in.

Audience walkouts numbered well over 200 at the New York premiere on April 3, 1968, and the next day's reviews were almost uniformly negative. Writing in the Village Voice, Andrew Sarris called the movie "a thoroughly uninteresting failure and the most damning demonstration yet of Stanley Kubrick's inability to tell a story coherently and with a consistent point of view." And yet that afternoon, a long line -- comprised predominantly of younger people -- extended down Broadway, awaiting the first matinee. The Cannes Film Festival will celebrate the 50th anniversary of "2001: A Space Odyssey" with the world premiere of an unrestored 70mm print, introduced by Christopher Nolan. The event is set for May 12 as part of the Cannes Classics program. The screening will also be attended by members of Kubrick's family, including his daughter Katharina Kubrick and his longtime producing partner and brother-in-law Jan Harlan.

Researchers using Hubble space telescope data have spotted Icarus (aka MACS J1149+2223 Lensed Star 1), a blue supergiant whose light was emitted when it was 9 billion light years away from Earth -- over 100 times farther than the previous record-setter. According to Engadget, "They captured the star thanks to a rare, ideal gravitational lensing effect where the star's light was magnified not only by the gravity of an in-between galaxy cluster 5 billion light years from Earth, but by a star inside that cluster." From the report: Observers had been keeping close watch on the cluster since 2014, when they'd detected a supernova that turned out to be present in a galaxy 9 billion light years away. They realized Icarus was present in April 2016, when a point of light near the supernova seemed to change brightness. Don't get too attached to this new discovery. With this kind of distance, Icarus has long-since turned into a neutron star or black hole. The findings are still advancing science in ways you might not expect, however. As the Guardian noted, the Icarus study ruled out a theory that dark matter consists of black holes. If that had been the case, they would have brightened Icarus even more. And if nothing else, this proves that humanity can detect more than just the largest and brightest celestial objects at these kinds of distances.

Security guru Bruce Schneier warns that "thousands of companies" are spying on us and manipulating us for profit. An anonymous reader quotes his article on CNN: Harvard Business School professor Shoshana Zuboff calls it "surveillance capitalism." And as creepy as Facebook is turning out to be, the entire industry is far creepier. It has existed in secret far too long, and it's up to lawmakers to force these companies into the public spotlight, where we can all decide if this is how we want society to operate and -- if not -- what to do about it...

Surveillance capitalism drives much of the internet. It's behind most of the "free" services, and many of the paid ones as well. Its goal is psychological manipulation, in the form of personalized advertising to persuade you to buy something or do something, like vote for a candidate. And while the individualized profile-driven manipulation exposed by Cambridge Analytica feels abhorrent, it's really no different from what every company wants in the end... Surveillance capitalism is deeply embedded in our increasingly computerized society, and if the extent of it came to light there would be broad demands for limits and regulation. But because this industry can largely operate in secret, only occasionally exposed after a data breach or investigative report, we remain mostly ignorant of its reach...

Regulation is the only answer.The first step to any regulation is transparency. Who has our data? Is it accurate? What are they doing with it? Who are they selling it to? How are they securing it? Can we delete it...? The market can put pressure on these companies to reduce their spying on us, but it can only do that if we force the industry out of its secret shadows.
The article also insists that "None of this is new," pointing out that companies like Facebook and Google offer their free services in exchange for your data.

But he also notes that there are now already 2,500 to 4,000 data brokers just in the U.S., including Equifax.

Apple is launching a major privacy push, with software updates across all its devices to introduce new data privacy information immediately, with an updated website offering new privacy management tools to follow in May. From a report: Thursday's updates (macOS 10.13.4, iOS11.3 and tvOS 11.3) are prompted by the enormous new European data protection regulation GDPR, and have been in the works since at least January. But they come at a good time for the company, whose head Tim Cook has been merrily capitalising on the Facebook/Cambridge Analytica scandal, publicly rebuking Mark Zuckerberg over the social network's business model. For users of the company's devices, the biggest change will be the introduction of a unified data privacy iconography, which now shows up alongside detailed information about how Apple uses personal data for its various first-party services. "Apple believes privacy is a fundamental human right," the company will tell every user the first time they turn on their devices after the update, "so every Apple product is designed to minimise the collection and use of your data, use on-device processing whenever possible, and provide transparency and control over your information."

A distant galaxy that appears completely devoid of dark matter has baffled astronomers and deepened the mystery of the universe's most elusive substance. The Guardian reports: The absence of dark matter from a small patch of sky might appear to be a non-problem, given that astronomers have never directly observed dark matter anywhere. However, most current theories of the universe suggest that everywhere that ordinary matter is found, dark matter ought to be lurking too, making the newly observed galaxy an odd exception. Dark matter's existence is inferred from its gravitational influence on visible objects, which suggests it dominates over ordinary matter by a ratio of 5:1. Some of the clearest evidence comes from tracking stars in the outer regions of galaxies, which consistently appear to be orbiting faster than their escape velocity, the threshold speed at which they ought to break free of the gravitational binds holding them in place and slingshot into space. This suggests there is unseen, but substantial, mass holding stars in orbit. In the Milky Way there is about 30 times more dark matter than normal matter. The latest observations focused on an ultra-diffuse galaxy -- ghostly galaxies that are large but have hardly any stars -- called NGC 1052-DF2. The team tracked the motions of 10 bright star clusters and found that they were traveling way below the velocities expected. The velocities gave an upper estimate for the galactic mass of 400 times lower than expected. The researchers described their discovery in the journal Nature.

An anonymous reader writes: The Guardian reports of a recent paper, published in the journal Energy and Environmental Science, that helps explain how wind and solar energy can power most of the United States: "The authors analyzed 36 years of hourly weather data (1980-2015) in the U.S. They calculated the available wind and solar power over this time period and also included the electrical demand in the U.S. and its variation throughout the year. With this information, the researchers considered two scenarios. In scenario 1, they imagined wind and solar installations that would be sufficient to supply 100% of the U.S. electrical needs. In the second scenario, the installations would be over-designed; capable of providing 150% of the total U.S. electrical need. But the authors recognize that just because a solar panel or a wind turbine can provide all our energy, it doesn't mean that will happen in reality. It goes back to the prior discussion that sometimes the wind just doesn't blow, and sometimes the sun isn't shining. With these two scenarios, the authors then considered different mixes of power, from all solar to all wind. They also included the effect of aggregation area, that is, what sized regions are used to generate power. Is your power coming from wind and solar in your neighborhood, your city, your state or your region?

The authors found that with 100% power capacity and no mechanism to store energy, a wind-heavy portfolio is best (about 75% wind, 25% solar) and using large aggregate regions is optimal. It is possible to supply about 75-80% of U.S. electrical needs. If the system were designed with excess capacity (the 150% case), the U.S. could meet about 90% of its needs with wind and solar power. The authors modified their study to allow up to 12 hours of US energy storage. They then found that the 100% capacity system fared even better (about 90% of the country's energy) and the optimal balance was now more solar (approximately 70% solar and 30% wind). For the over-capacity system, the authors found that virtually all the country's power needs could be met with wind, solar, and storage."
