The Verge reports that "Tokyo-based Bitcoin exchange Mt. Gox lost $400 million worth of bitcoins in February. Its management said the amount was stolen after hackers exploited a transaction bug to divert the funds, but some of Mt. Gox's users are not so sure, suggesting instead that the exchange's owners pocketed the cash. Now, facing silence from those owners about the fate of the money and the methods by which 6 percent of all of the Bitcoin in the world could have been stolen, a group of hackers claims it has broken into the bankrupted Bitcoin exchange's network to get answers. ... Forbes reports that the group gained access to the personal blog and Reddit account of Mark Karpeles, Mt. Gox's CEO. The hackers used the platforms to post a message that claimed Karpeles still had access to some of the bitcoins that he'd reported stolen. In support of the claim, they uploaded a series of files that included a spreadsheet of more than a million trades, Karpeles' home addresses, and a screenshot purportedly confirming the hackers' access to the data."

An anonymous reader writes "During an exploratory dig to extend one of L.A.'s subway lines (yes! Los Angeles actually does have an underground), a host of fossils from the Ice Age were uncovered, including the skull of a sea lion. The dig site is close to the La Brea Tar Pits, where the preserved remains of various plants and animals were discovered in the early 1900s. The La Brea Tar Pit fossils are estimated to be between 11,000-55,000 years old, and the most common animals found were dire wolves."

There's been some positive news in the last year (and the last few) for American cellphone customers: certainly there's more visible competition for their business among the largest players in the market. Nonetheless, the Wall Street Journal reports that while more competition may translate into some more attractive service bundles, flexibility in phone options, or smoother customer service, it doesn't actually mean that the customers are on average reaping one of the benefits that competition might be expected to provide: lower price. Instead, the bills for customers on the major wireless providers have actually gone up, if not dramatically, in recent months — which means U.S. cell service remains much more expensive than it is in many other countries. The article could stand a sidebar on MVNOs and other low-cost options, though -- I switched to one of these from AT&T, and now pay just under $40 for one version of the new normal of unlimited talk and text, plus quite limited (1GB) data, but still using AT&T towers. Has your own cost to talk gone up or down?

As reported by the Washington Post, Edward Snowden denies in no uncertain terms the idea that he failed to go through proper channels to expose what he thought were troubling privacy violations being committed by the NSA, and that he observed as a contractor employed by the agency. The article begins: "[Snowden] said he repeatedly tried to go through official channels to raise concerns about government snooping programs but that his warnings fell on the deaf ears. In testimony to the European Parliament released Friday morning, Snowden wrote that he reported policy or legal issues related to spying programs to more than 10 officials, but as a contractor he had no legal avenue to pursue further whistleblowing." Further, "Elsewhere in his testimony, Snowden described the reaction he received when relating his concerns to co-workers and superiors. The responses, he said, fell into two camps. 'The first were well-meaning but hushed warnings not to "rock the boat," for fear of the sort of retaliation that befell former NSA whistleblowers like Wiebe, Binney, and Drake.' All three of those men, he notes, were subject to intense scrutiny and the threat of criminal prosecution."

sciencehabit writes "New data show that after remaining more or less steady for a decade, the number of investigators with National Institutes of Health (NIH) funding dropped sharply last year by at least 500 researchers and as many as 1000. Although not a big surprise—it came the same year that NIH's budget took a 5% cut—the decline suggests that a long-anticipated contraction in the number of labs supported by NIH may have finally begun."

Georgetown researcher (and executive dean of Georgetown's medical school) Howard Federoff has taken a "systems" approach to diagnostics for certain chronic diseases. By comparing blood samples taken from patients who subsequently developed Alzheimer's to blood samples after the disease has manifested, Federoff has identified markers and created a blood test that is described as "90 percent accurate" (the BBC article does not delve into the ratio of false positives to false negatives) in predicting whether a currently healthy patient is likely to develop Alzheimer's in the following three years. Understandably, this raises some ethical and practical questions. What would you do differently if this test came back positive for yourself? Or for a parent? Here's the (paywalled) paper, at Nature Medicine.

An anonymous reader writes with an excerpt from an intriguing article at TechDirt about the sometimes very low-tech methods of the East German Stasi. They may have been using more pencils than computers, but they were gathering information on their targets using the same kind of metadata whose significance the U.S. government has lately been downplaying: "They amassed dossiers on about one quarter of the population of the country during the Communist regime. But their spycraft — while incredibly invasive — was also technologically primitive by today's standards. While researching my book Dragnet Nation, I obtained the above hand drawn social network graph and other files from the Stasi Archive in Berlin, where German citizens can see files kept about them and media can access some files, with the names of the people who were monitored removed. The graphic shows forty-six connections, linking a target to various people (an 'aunt,' 'Operational Case Jentzsch,' presumably Bernd Jentzsch, an East German poet who defected to the West in 1976), places ('church'), and meetings ('by post, by phone, meeting in Hungary')."
