Up to 95% of all reported trading in bitcoin is artificially created by unregulated exchanges, according to a new study [PDF], raising fresh doubts about the nascent market following a steep decline in prices over the past year. From a report: Fraudulent trading volume has dogged cryptocurrency trading for years, but the extent of the market manipulation has been difficult to determine. Bitwise Asset Management said its analysis of trading activity at 81 exchanges over four days in March indicates that the actual market for bitcoin is far smaller than previously thought. The San Francisco-based company submitted its research to the U.S. Securities and Exchange Commission with an application to launch a bitcoin-based exchange-traded fund. The study, made public Thursday, is an attempt to alleviate the agency's longstanding concerns that a bitcoin ETF would leave investors exposed to fraud and market manipulation. Bitwise's fund, if approved, would be based upon the 5% of trading it considers legitimate, said Matthew Hougan, Bitwise's head of global research. That volume comes from 10 regulated exchanges that can verify that their trading data and customers are real. This slice of the market, he said, is well regulated, transparent and efficient. "I hope everyone sees there is a real market for bitcoin," he said.

An anonymous reader quotes a report from The Guardian: Facebook employees were aware of concerns about "improper data-gathering practices" by Cambridge Analytica months before the Guardian first reported, in December 2015, that the political consultancy had obtained data on millions from an academic. The concerns appeared in a court filing by the attorney general for Washington DC and were subsequently confirmed by Facebook. The new information "could suggest that Facebook has consistently mislead [sic]" British lawmakers "about what it knew and when about Cambridge Analytica," tweeted Damian Collins, the chair of the House of Commons digital culture media and sport select committee (DCMS) in response to the court filing. In a statement, a company spokesperson said: "Facebook absolutely did not mislead anyone about this timeline." After publication of this article, the spokesperson acknowledged that Facebook employees heard rumors of data scraping by Cambridge Analytica in September 2015. The spokesperson said that this was a "different incident" from Cambridge Analytica's acquisition of a trove of data about as many as 87 million users that has been widely reported on for the past year. "In September 2015 employees heard speculation that Cambridge Analytica was scraping data, something that is unfortunately common for any internet service," the spokesperson said. "In December 2015, we first learned through media reports that Kogan sold data to Cambridge Analytica, and we took action. Those were two different things." The filing raised questions about when Facebook first learned about the misuse of personal data by Cambridge Analytica, the now defunct political consultancy.

Google's Stadio cloud-gaming service may be intercepted by a similar service from Walmart. According to a report from US Gamer, the American retail giant is looking into launching its own cloud gaming service. From the report: Multiple sources familiar with Walmart's plans, who wish to remain anonymous, confirmed to USG that the retail giant is exploring its own platform to enter in the now-competitive video game streaming race. No other details were revealed other than it will be a streaming service for video games, and that Walmart has been speaking with developers and publishers since earlier this year and throughout this year's Game Developers Conference. Walmart's discussions with developers for its streaming service have been secretive, and it's unclear how far along the service is in-development. But our sources are confident that this is a space Walmart is trying to move into. Though Walmart might sound like a strange company to be jumping into the streaming tech space, the move isn't wholly unexpected. In recent years due to competition from Amazon, Walmart has been increasingly looking into more tech-focused markets beyond its traditional physical retail chain. Over time, Walmart has integrated its physical stores with its large online presence, offering deliveries, app integrations, and in-store pick up services. Walmart also has a technology arm in Silicon Valley called Walmart Labs, which has 6,000 employees and develops tech for Walmart's digital presence. In addition it boasts tools like Cruxlux, which is a search engine designed to reveal the connection between any two people, places, or things. Finally, Walmart has a data center unofficially called Area 71 in Caverna, Missouri which holds over 460 trillion bytes of data. Data centers are a centerpiece of Google's Stadia streaming service and companies like Microsoft, Amazon, and Apple also own powerful data facilities, all of whom are also coincidentally working in streaming technology.

The recent Boeing 737 MAX crashes involving an Ethiopian Airlines flight and a Lion Air flight may have been a result of two missing safety features that Boeing charged airlines extra for (Warning: source may be paywalled; alternative source). The New York Times reports that many low-cost carriers like Indonesia's Lion Air opted not to buy them so they could save money, even though some of these systems are fundamental to the plane's operations. "Now, in the wake of the two deadly crashes involving the same jet model, Boeing will make one of those safety features standard as part of a fix to get the planes in the air again," the report says. From the report: It is not yet known what caused the crashes of Ethiopian Airlines Flight 302 on March 10 and Lion Air Flight 610 five months earlier, both after erratic takeoffs. But investigators are looking at whether a new software system added to avoid stalls in Boeing's 737 Max series may have been partly to blame. Faulty data from sensors on the Lion Air plane may have caused the system, known as MCAS, to malfunction, authorities investigating that crash suspect. The jet's software system takes readings from one of two vanelike devices called angle of attack sensors that determine how much the plane's nose is pointing up or down relative to oncoming air. When MCAS detects that the plane is pointing up at a dangerous angle, it can automatically push down the nose of the plane in an effort to prevent the plane from stalling. Boeing's optional safety features, in part, could have helped the pilots detect any erroneous readings. One of the optional upgrades, the angle of attack indicator, displays the readings of the two sensors. The other, called a disagree light, is activated if those sensors are at odds with one another. The angle of attack indicator will remain an option that airlines can buy. Neither feature was mandated by the Federal Aviation Administration. All 737 Max jets have been grounded. "Boeing will soon update the MCAS software, and will also make the disagree light standard on all new 737 Max planes," the report adds, citing a person familiar with the changes. "Boeing started moving on the software fix and the equipment change before the crash in Ethiopia." Slashdot reader Futurepower(R) adds to the story: The FBI has joined the criminal investigation into the certification of the Boeing 737 MAX, lending its considerable resources to an inquiry already being conducted by U.S. Department of Transportation agents, according to people familiar with the matter. "The federal grand jury investigation, based in Washington, D.C., is looking into the certification process that approved the safety of the new Boeing plane, two of which have crashed since October.

An anonymous reader quotes a report from Recode: After years of circling the TV business, Apple is finally ready to make its big splash: On Monday it will unveil its new video strategy, along with some of the new big-budget TV shows it is funding itself. One thing Apple won't do is unveil a serious competitor to Netflix, Hulu, Disney, or any other entertainment giant trying to sell streaming video subscriptions to consumers. Instead, Apple's main focus -- at least for now -- will be helping other people sell streaming video subscriptions and taking a cut of the transaction. Apple may also sell its own shows, at least as part of a bundle of other services. But for now, Apple's original shows and movies should be considered very expensive giveaways, not the core product. All of this might very well work. Apple has an installed base of 1.4 billion users, and some of them will buy the things Apple promotes: Look at the success of Apple Music, which launched seven years after Spotify but quickly amassed 50 million subscribers due to a free trial period and prominent real estate on Apple's devices. Another reason this could work: Amazon has already been very successful with its own version of the same idea. Facebook is also bullish on selling TV subscriptions and is pushing would-be partners to sign up so it can launch later this spring or summer, according to industry sources. Similarly, Comcast (which is a minority investor in Vox Media, which owns this site) is rolling out Flex, a $5-a-month service that gives you a bunch of free content (some of which you can also get other places) and the ability to easily buy HBO, Showtime, etc. Instead of offering exclusive content, Comcast is offering subscribers a Roku-like streaming box. According to people who've talked to Apple about its plans, Apple's new TV service will consist of selling TV subscription apps surrounded by millions of other apps in its main app store. "Apple plans on making a new storefront that's much more prominent for those who use Apple TV boxes and other Apple hardware," reports Recode. "It will also be able to offer its own bundles -- for instance, it could offer a package of HBO, Showtime, and Starz at a price that's lower than you'd pay for each pay TV service on its own."

the_newsbeagle writes: An FDA advisory committee met today to consider approving the NeuroAD device, which is supposed to help with the cognitive symptoms of Alzheimer's disease. The device uses a combination of brain stimulation and cognitive training tasks to strengthen the neural circuits involved in language, memory, and other components of cognition. The treatment requires patients to come to the clinic daily for 1-hour sessions. Regulators in Israel and Europe have already approved the device. The CEO of the company behind the device, Neuronix, says that they're not attempting to cure the underlying biological causes of Alzheimer's. "We're attempting to modify the course of the disease," he says. The cognitive improvements last for up to a year, after which they fade away.
