An anonymous reader quotes a report from The Verge: Microsoft and Google are jointly disclosing a new CPU security vulnerability that's similar to the Meltdown and Spectre flaws that were revealed earlier this year. Labelled Speculative Store Bypass (variant 4), the latest vulnerability is a similar exploit to Spectre and exploits speculative execution that modern CPUs use. Browsers like Safari, Edge, and Chrome were all patched for Meltdown earlier this year, and Intel says "these mitigations are also applicable to variant 4 and available for consumers to use today." However, unlike Meltdown (and more similar to Spectre) this new vulnerability will also include firmware updates for CPUs that could affect performance. Intel has already delivered microcode updates for Speculative Store Bypass in beta form to OEMs, and the company expects them to be more broadly available in the coming weeks. The firmware updates will set the Speculative Store Bypass protection to off-by-default, ensuring that most people won't see negative performance impacts.
"If enabled, we've observed a performance impact of approximately 2-8 percent based on overall scores for benchmarks like SYSmark 2014 SE and SPEC integer rate on client 1 and server 2 test systems," explains Leslie Culbertson, Intel's security chief. As a result, end users (and particularly system administrators) will have to pick between security or optimal performance. The choice, like previous variants of Spectre, will come down to individual systems and servers, and the fact that this new variant appears to be less of a risk than the CPU flaws that were discovered earlier this year.Read Replies (0)

Former Commissioner Mignon Clyburn, who left the agency this month, has taken aim at it in an interview, saying the agency has abandoned its mission to safeguard consumers and protect their privacy and speech. From her interview with ArsTechnica: "I'm an old Trekkie," Clyburn told Ars in a phone interview, while comparing the FCC's responsibility to the Star Trek fictional universe's Prime Directive. "I go back to my core, my prime directive of putting consumers first." If the FCC doesn't do all it can to bring affordable communications services to everyone in the US, "our mission will not be realized," she said. The FCC's top priority, as set out by the Communications Act, is to make sure all Americans have "affordable, efficient, and effective" access to communications services, Clyburn said. But too often, the FCC's Republican majority led by Chairman Ajit Pai is prioritizing the desires of corporations over consumers, Clyburn said. "I don't believe it's accidental that we are called regulators," she said. "Some people at the federal level try to shy away from that title. I embrace it." Clyburn said that deregulation isn't bad in markets with robust competition, because competition itself can protect consumers. But "that is just not the case" in broadband, she said. "Let's just face it, [Internet service providers] are last-mile monopolies," she told Ars. "In an ideal world, we wouldn't need regulation. We don't live in an ideal world, all markets are not competitive, and when that is the case, that is why agencies like the FCC were constructed. We are here as a substitute for competition." Broadband regulators should strike a balance that protects consumers and promotes investment from large and small companies, she said. "If you don't regulate appropriately, things go too far one way or the other, and we either have prices that are too high or an insufficient amount of resources or applications or services to meet the needs of Americans," Clyburn said.Read Replies (0)

Consumer Reports published their review of the Tesla Model 3 today. The product review site liked the vehicle's range of the battery and agile handling, but had issues with braking, controls, and ride quality. Overall, it failed to get a recommendation. CNBC highlights the key shortfalls: "Our testers also found flawsâ"big flawsâ"such as long stopping distances in our emergency braking test and difficult-to-use controls," said a review in the publication. In particular, the car's stopping distance of 152 feet from a speed of 60 miles per hour was slower than any of its contemporaries, including the Ford F-150, a full-size pickup. The location of almost all of Tesla's controls on a touchscreen and the vehicle's ride quality were also factors in the group's decision. Tesla issued a statement in response to Consumer Reports' stopping distance claim: "Tesla's own testing has found braking distances with an average of 133 feet when conducting the 60-0 mph stops using the 18-inch Michelin all season tire and as low as 126 feet with all tires currently available. Stopping distance results are affected by variables such as road surface, weather conditions, tire temperature, brake conditioning, outside temperature, and past driving behavior that may have affected the brake system. Unlike other vehicles, Tesla is uniquely positioned to address more corner cases over time through over-the-air software updates, and it continually does so to improve factors such as stopping distance."Read Replies (0)

In early 2016, two planetary scientists declared that a ghost planet is hiding in the depths of the solar system, well beyond the orbit of Pluto. Their claim, which they made based on the curious orbits of distant icy worlds, quickly sparked a race to find this so-called Planet Nine -- a planet that is estimated to be about 10 times the mass of Earth. From a report: Now, astronomers are reporting that they have spotted another distant world -- perhaps as large as a dwarf planet -- whose orbit is so odd that it is likely to have been shepherded by Planet Nine. The object confirms a specific prediction made by Konstantin Batygin and Michael Brown, the astronomers at the California Institute of Technology who first argued for Planet Nine's existence. "It's not proof that Planet Nine exists," said David Gerdes, an astronomer at the University of Michigan and a co-author on the new paper. "But I would say the presence of an object like this in our solar system bolsters the case for Planet Nine." Gerdes and his colleagues spotted the new object in data from the Dark Energy Survey, a project that probes the acceleration in the expansion of the universe by surveying a region well above the plane of the solar system. This makes it an unlikely tool for finding objects inside the solar system, since they mostly orbit within the plane. But that is exactly what makes the new object unique: Its orbit is tilted 54 degrees with respect to the plane of the solar system. It's something Gerdes did not expect to see. Batygin and Brown, however, predicted it. The rocky body is being described as 2015 BP519. Quanta magazine has more details.Read Replies (0)

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.Read Replies (0)

Amazon is creating another app store, but it's not for consumers. From a report: Instead, the online retail giant will for the first time put its seal of approval on a bunch of third-party apps intended for professional sellers with its new Marketplace Appstore. It launches to sellers starting Monday, the company said. CNET reported on plans for the app store earlier this month. The new app store, which will be available in North America through Amazon's main hub for sellers called Seller Central, will include tools to handle pricing, inventory, advertising and other needs for pro sellers. The app store will be introduced to sellers slowly to ensure a smooth rollout. "Many developers have innovated and created applications that complement our tools and integrate with our service," Amazon said in a statement Monday. "We created the Marketplace Appstore to help businesses more easily discover these applications, streamline their business operations, and ultimately create a better experience for our customers."Read Replies (0)

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.Read Replies (0)

An anonymous reader shares a report: Several advocacy groups have banded together for a campaign that calls upon the US Federal Trade Commission to intervene and break up Facebook into smaller companies -- and more specifically to split off the Messenger, Instagram, and WhatsApp services from the mother company. The campaign, named Freedom from Facebook, was set into motion today by eight groups -- Demand Progress, Citizens Against Monopoly, Content Creators Coalition, Jewish Voice for Peace, MoveOn, Mpower Change, Open Markets Institute, and SumOfUs, respectively. Through a dedicated website, the eight advocacy groups are urging users to file a petition with the FTC on the grounds that Facebook has become a monopoly. The campaign's motto is "It's time to make Facebook safe for democracy." "Facebook and Mark Zuckerberg have amassed a scary amount of power," the campaign's website reads. "Facebook unilaterally decides the news that billions of people around the world see every day."Read Replies (0)

A coalition of human rights and technology groups released a new declaration on machine learning standards, calling on both governments and tech companies to ensure that algorithms respect basic principles of equality and non-discrimination. The Verge reports: Called The Toronto Declaration, the document focuses on the obligation to prevent machine learning systems from discriminating, and in some cases violating, existing human rights law. The declaration was announced as part of the RightsCon conference, an annual gathering of digital and human rights groups. "We must keep our focus on how these technologies will affect individual human beings and human rights," the preamble reads. "In a world of machine learning systems, who will bear accountability for harming human rights?" The declaration has already been signed by Amnesty International, Access Now, Human Rights Watch, and the Wikimedia Foundation. More signatories are expected in the weeks to come.
Beyond general non-discrimination practices, the declaration focuses on the individual right to remedy when algorithmic discrimination does occur. "This may include, for example, creating clear, independent, and visible processes for redress following adverse individual or societal effects," the declaration suggests, "[and making decisions] subject to accessible and effective appeal and judicial review."Read Replies (0)

An anonymous reader quotes a report from Scientific American: UCLA neuroscientists reported Monday that they have transferred a memory from one animal to another via injections of RNA, a startling result that challenges the widely held view of where and how memories are stored in the brain. The finding from the lab of David Glanzman hints at the potential for new RNA-based treatments to one day restore lost memories and, if correct, could shake up the field of memory and learning. The researchers extracted RNA from the nervous systems of snails that had been shocked and injected the material into unshocked snails. RNA's primary role is to serve as a messenger inside cells, carrying protein-making instructions from its cousin DNA. But when this RNA was injected, these naive snails withdrew their siphons for extended periods of time after a soft touch. Control snails that received injections of RNA from snails that had not received shocks did not withdraw their siphons for as long.
Glanzman's group went further, showing that Aplysia sensory neurons in Petri dishes were more excitable, as they tend to be after being shocked, if they were exposed to RNA from shocked snails. Exposure to RNA from snails that had never been shocked did not cause the cells to become more excitable. The results, said Glanzman, suggest that memories may be stored within the nucleus of neurons, where RNA is synthesized and can act on DNA to turn genes on and off. He said he thought memory storage involved these epigenetic changes -- changes in the activity of genes and not in the DNA sequences that make up those genes -- that are mediated by RNA. This view challenges the widely held notion that memories are stored by enhancing synaptic connections between neurons. Rather, Glanzman sees synaptic changes that occur during memory formation as flowing from the information that the RNA is carrying. The study has been published in the journal eNeuro.Read Replies (0)
