A Thousand Kilobots Self-Assemble Into Complex Shapes 56
An anonymous reader writes "Researchers at Harvard's Self-Organizing Systems Research Group—describe their thousand-robot swarm in a paper published today in Science (they actually built 1024 robots). In the past, researchers have only been able to program at most a couple hundred robots to work together. Now, these researchers have programmed the biggest robot swarm yet. Alone, the simple little robot can't do much, but working with 1,000 or more like-minded fellow bots, it becomes part of a swarm that can self-assemble into any two-dimensional shape. These are some of the first steps toward creating huge herds of tiny robots that form larger structures—including bigger robots."
Why Hasn't This Asteroid Disintegrated? 74
sciencehabit writes: Planetary scientists have found an asteroid spinning too fast for its own good. The object, known as 1950 DA, whips around every 2.1 hours, which means that rocks on its surface should fly off into space. What's keeping the remaining small rocks and dust on the surface? The researchers suggest van der Waals forces, weak forces caused by the attraction of polar molecules, which have slightly different charges on different sides of the molecule. For example, water molecules exhibit surface tension because of van der Waals forces, because the negative charge of one water molecule's oxygen atom is attracted to nearby water molecules' hydrogen atoms, which have a positive charge at their surfaces. Similar attractions could be occurring between molecules on the surfaces of different pieces of dust and rock. Such forces would be comparable to those that caused lunar dust to stick to astronauts' space suits.
San Jose Police Apologize For Hiding Drone Program, Halts Until Further Review 59
v3rgEz (125380) writes As part of MuckRock's Drone Census, the San Jose Police twice denied having a drone in public records requests — until the same investigation turned up not only a signed bid for a drone but also a federal grant giving them money for it. Now, almost a full year after first denying they had a drone, the department has come clean and apologized for hiding the program, promising more transparency and to pursue federal approval for the program, which the police department had, internally, claimed immunity from previously.
Why Morgan Stanley Is Betting That Tesla Will Kill Your Power Company 502
Jason Koebler (3528235) writes One major investment giant has now released three separate reports arguing that Tesla Motors is going to help kill power companies off altogether. Earlier this year, Morgan Stanley stirred up controversy when it released a report that suggested that the increasing viability of consumer solar, paired with better battery technology—that allows people to generate, and store, their own electricity—could send the decades-old utility industry into a death spiral. Then, the firm released another one. Now, it's tripling down on the idea with yet another report that spells out how Tesla and home solar will "disrupt" utilities.
Want To Work Without Prying Eyes? Try Wearing a Body Sock 75
Nerval's Lobster writes The "Compubody Sock," which anyone with knitting skills can make at home, is a giant sock-hoodie-bag in which you place your laptop or tablet, along with your head and hands, giving you total privacy while freaking out anyone who happens to be sitting next to you. Designer Becky Stern told Forbes' Kashmir Hill that the Sock was meant more as commentary on privacy and device addiction; even so, considering how NSA employees reportedly drape themselves in hoods in order to thwart hidden cameras while typing in passwords, it's not outside the realm of possibility that an ultra-paranoid someone could find a practical use for a body sock. But that paranoid android better have expert knitting skills: putting together the Sock necessitates a whole lot of steps ("Purl 5, purl 2 together, purl 1, turn the work," etc.). Your other option, of course, is to simply avoid working on sensitive stuff in public.
Ask Slashdot: What To Do About the Sorry State of FOSS Documentation? 430
First time accepted submitter TWX writes I've been out of computers as a serious home-hobby for many years and in returning I'm aghast at the state of documentation for Open Source projects. The software itself has changed significantly in the last decade, but the documentation has failed to keep pace; most of what I'm finding applies to versions long since passed or were the exact same documents from when I dropped-out of hobbyist computing years ago. Take Lightdm on Ubuntu 14.04 for example- its entire configuration file structure has been revamped, but none of the documentation for more specialized or advanced uses of Lightdm in previous versions of Ubuntu has been updated for this latest release. It's actually harder now to configure some features than it was a decade ago. TLDP is close to a decade out-of-date, fragmentation between distributions has grown to the point that answers from one distro won't readily apply to another, and web forums for even specific projects are full of questions without answers, or those that head off into completely unrelated discussion, or with snarky, "it's in the documentation, stupid!" responses. Where do you go for your FOSS documentation and self-help?
Wearable Robot Adds Two Fingers To Your Hand 77
rtoz writes: Researchers at MIT have developed a robot that enhances the grasping motion of the human hand. This wrist-wearable robot adds two extra fingers that respond to movements in the wearer's hand. The robotic fingers are on either side of the hand — one outside the thumb, and the other outside the little finger. A control algorithm enables it to move in sync with the wearer's fingers to grasp objects of various shapes and sizes. With the assistance of these extra fingers, the user can grasp objects that are usually too difficult to pick up and manipulate with a single hand.
White House Punts On Petition To Allow Tesla Direct Sales 382
First time accepted submitter neanderslob (1207704) writes Last Friday, over a year after the petition gained the required signatures for a response, the White House rejected a We the People petition to "Allow Tesla Motors to sell directly to consumers in all 50 states." The letter went on to defend the administration by citing their initiatives "in promoting vehicle efficiency." In response, Tesla is firing back, blasting the White House for a lack of leadership on the issue and stating "138,469 people signed the petition asking the White House to allow Tesla Motors to sell directly to consumers in all 50 states. More than a year later, at 7.30pm EST on Friday as most of America prepared for the weekend, the White House released its disappointing response to those people. Rather than seize an opportunity to promote innovation and support the first successful American car company to be started in more than a century, the White House issued a response that was even more timid than its rejection of a petition to begin construction of a Death Star."
There's a legal issue here: the executive can't just wave state law aside. But they could suggest Congress write new laws instead of just noting that Congress would need to take action.

... they also have ground requirements much closer to 'airport with atypically long runway'
If that's what they need then the Irish government should look at creating a spaceport near Shannon, which has a gigantic runway,suitable both for the frequent US military stopovers to and from the Middle East, and (I was told) for the Shuttle, should an emergency ever have arisen requiring a landing in Europe if Edwards or elsewhere was unavailable. But that may just be local pride
Economist: File Sharing's Impact On Movies Is Modest At Most 214
First time accepted submitter SillyBoy123 writes What is the impact of file sharing releases on the movie industry? Ask the studios and they will say billions. An economist named Koleman Strumph is presenting a paper at the National Bureau of Economics this week that tries to estimate the crowd out from these releases. His conclusion: "I find that file sharing has only a modest impact on box office revenue." In fact, Strumph finds that file sharing before the official release of a movie can actually be beneficial to revenues: "One consistent result is that file sharing arrivals shortly before the theatrical opening have a modest positive effect on box office revenue. One explanation is that such releases create greater awareness of the film. This is also the period of heaviest
advertising. In conjunction with the main estimates, this suggests that free and potentially degraded goods such as the lower quality movies available on file sharing networks can have some beneficial effects on intellectual property."
How Deep Does the Multiverse Go? 202
StartsWithABang writes Our observable Universe is a pretty impressive entity: extending 46 billion light-years in all directions, filled with hundreds of billions of galaxies and having been around for nearly 14 billion years since the Big Bang. But what lies beyond it? Sure, there's probably more Universe just like ours that's unobservable, but what about the multiverse? Finally, a treatment that delineates the difference between the ideas that are thrown around and explains what's accepted as valid, what's treated as speculative, and what's completely unrelated to anything that could conceivably ever be observed from within our Universe.
Airbus Patents Windowless Cockpit That Would Increase Pilots' Field of View 468
Zothecula writes Imagine showing up at the airport to catch your flight, looking at your plane, and noticing that instead of windows, the cockpit is now a smooth cone of aluminum. It may seem like the worst case of quality control in history, but Airbus argues that this could be the airliner of the future. In a new US patent application, the EU aircraft consortium outlines a new cockpit design that replaces the traditional cockpit with one that uses 3D view screens instead of conventional windows.
Goldman Sachs Demands Google Unsend One of Its E-mails 346
rudy_wayne (414635) writes A Goldman Sachs contractor was testing internal changes made to Goldman Sachs system and prepared a report with sensitive client information, including details on brokerage accounts. The report was accidentally e-mailed to a 'gmail.com' address rather than the correct 'gs.com' address. Google told Goldman Sachs on June 26 that it couldn't just reach into Gmail and delete the e-mail without a court order. Goldman Sachs filed with the New York Supreme Court, requesting "emergency relief" to avoid a privacy violation and "avoid the risk of unnecessary reputational damage to Goldman Sachs."
Ninety-Nine Percent of the Ocean's Plastic Is Missing 304
sciencehabit writes Millions of tons. That's how much plastic should be floating in the world's oceans, given our ubiquitous use of the stuff. But a new study (abstract) finds that 99% of this plastic is missing. One disturbing possibility: Fish are eating it. If that's the case, "there is potential for this plastic to enter the global ocean food web," says Carlos Duarte, an oceanographer at the University of Western Australia, Crawley. "And we are part of this food web."
