afeeney writes: Researchers at the University of Bristol and Northwestern Polytechnical University in China have created acoustic vortices that can create microscopic centrifuges that rotate small particles. They compare this to a watchmaker's sonic screwdriver. So far, though, the practical applications include cell sorting and low-power water purification, rather than TARDIS operations. Appropriately enough, one of the researchers is named Bruce Drinkwater.
jan_jes writes: MIT researchers demonstrated an untethered miniature origami robot that self-folds, walks, swims, and degrades at ICRA 2015 in Seattle. A miniature robotic device that can fold-up on the spot, accomplish tasks, and disappear by degradation into the environment promises a range of medical applications but has so far been a challenge in engineering. This work presents a sheet that can self-fold into a functional 3D robot,actuate immediately for untethered walking and swimming, and subsequently dissolve in liquid. Further, the robot is capable of conducting basic tasks and behaviors, including swimming, delivering/carrying blocks, climbing a slope, and digging. The developed models include an acetone-degradable version, which allows the entire robot's body to vanish in a liquid. Thus this experimentally demonstrate the complete life cycle of this robot: self-folding,actuation, and degrading.
An anonymous reader writes with a report that Google yesterday announced at its I/O conference a photo-storage site known as Google Photos. Says the article: The new service is completely separate from Google+, something Google users have been requesting for eons. Google is declaring that Google Photos lets you backup and store "unlimited, high-quality photos and videos, for free." It's a bit creepy to see all the photos that Google still has on tap, including many that I've since deleted on my phone.
schwit1 writes: The Russian investigation into the latest Proton rocket failure has concluded that the failure was caused by a design failure in the rocket's third stage. The steering third stage engine failed due to excessive vibration as a result of an imbalance in a rotor of a pump unit. While it is always possible for new design issues to be discovered, I wonder why this problem hadn't been noticed in the decades prior to 2010, when the Proton began to have repeated failures.
retroworks writes: Integrated photonic devices are poised to play a key role in a wide variety of applications, ranging from optical interconnects and sensors to quantum computing. However, only a small library of semi-analytically designed devices is currently known. In an article in Nature Photonics, researchers demonstrate the use of an inverse design method that explores the full design space of fabricable devices and allows them to design devices with previously unattainable functionality, higher performance and robustness, and smaller footprints than conventional devices. The designed a silicon wavelength demultiplexer splits 1,300nm and 1,550nm light from an input waveguide into two output waveguides, and the team has fabricated and characterized several devices. The devices display low insertion loss (2dB), low crosstalk (100nm). The device footprint is 2.8×2.8m2, making this the smallest dielectric wavelength splitter.
ckwu with word that South Korean researchers have created the first UV-emitting quantum dots, and employed them in the creation of a flexible LED. Their achievement is notable because no one has previously succeeded in making quantum dots capable of emitting light at wavelengths shorter than 400 nm, which defines the upper range of the UV spectrum. Writes ckwu: To get quantum dots that emit UV, the researchers figured out how make them with light-emitting cores smaller than 3 nm in diameter. They did it by coating a light-emitting cadmium zinc selenide nanoparticle with a zinc sulfide shell, which caused the core to shrink to 2.5 nm. The quantum dots give off true UV light, at 377 nm. An LED made with the quantum dots could illuminate the anticounterfeiting marks on a paper bill. The article names a few applications of the technology, besides, including water sterilization and industrial applications.
agent elevator writes: IEEE Spectrum has a feature (part of its Hacking the Human OS issue) on the future of vagus nerve stimulation, a device-based therapy with the potential to treat a ridiculously wide variety of ailments: epilepsy, depression, stroke, tinnitus, heart failure, migraines, asthma, the list goes on. One problem is that, because it required an implant (a bit like a pacemaker), it was never anybody's first-choice therapy. But now there's a non-invasive version, a device you just hold to your neck twice a day for a few minutes. It's being trialed first for migraines and cluster headaches (which sound horrible). If it works, vagus nerve stimulation could compete directly with drug treatments on cost and convenience and it would let doctors find new ways to hack human physiology.
ClockEndGooner writes: A study conducted by the Netherlands Organization for Applied Scientific Research found that low frequency and long wavelength jet engine droning noise was significantly reduced in the fall after farmers plowed their fields near Amsterdam's Schiphol Airport. The remaining furrows "had multiple ridges to absorb the sound waves, deflected the sound and muted the noise." This led to the development of the Buitenschot Land Art Park, a buffer park featuring "land art" that has significantly reduced aircraft noise without requiring cuts in the number of allowed flights in and out of the airport. The land art park has also provided neighbors with additional recreational paths and sports fields in the same space.
baegucb sends a followup to the news from March that professional internet trolls were operating by the hundreds at factories in Russia. A woman hired to be one of these trolls, Lyudmila Savchuk, spoke to the media about her job, which led to her being fired. She's now suing her former employer and providing further details about how they operate. "The 'troll factory' operates based on very weird schemes, but all those firms are connected to each other, even though they are separate legal entities," she said. "I knew it was something bad, but of course I never suspected that it was this horrible and this large-scale." She describes how they flooded comment sections with pro-Putin responses, pushed out over 100 blog posts each shift, and doctored images to suit their employers' needs. Savchuk is now gathering activists to oppose this form of internet propaganda.
DeviceGuru writes: Russia-based Eltechs announced its ExaGear Desktop virtual machine last August, enabling Linux/ARMv7 SBCs and mini-PCs to run x86 software. That meant that users of the quad-core, Cortex-A7-based Raspberry Pi 2 Model B, could use it as well, although the software was not yet optimized for it. Now Eltechs has extended extended ExaGear to support earlier ARMv6 versions of the Raspberry Pi. The company also optimized the emulator for the Pi 2 allowing, for example, Pi 2 users to use automatically forwarding startup scripts.
blando writes: A trove of emails provided to The Intercept detail Russian schemes to obtain a crucial component for military thermal-imaging systems. Though emails about the thermal imaging systems date back as far as 2006, the plans to acquire them began in earnest much more recently, in 2013. To try to hide Russian involvement, a company called Cyclone established a new company in the Republic of Cyprus. They did so with the help of a company called Rayfast, which was owned by three other companies itself. After obfuscating the new company's ownership and military ties, they reached out to several Western companies who worked with the technology.
Sparrowvsrevolution writes: The dark web has become the go-to corner of the Internet to buy drugs, stolen financial data, guns...and counterfeit coupons for Clif bars and condoms? The FBI indicted Beauregard Wattigney yesterday for wire fraud and trademark counterfeiting on digital black market sites Silk Road and Silk Road 2. Wattigney allegedly spoofed coupons for dozens of products and sold collections of them online in exchange for Bitcoin. The FBI accused him of doing $1 million worth of collective damage to the companies he made coupons for, but a fraud consultancy believes the total financial cost of his actions was much higher. Wattigney also offered expensive lessons that taught people how to make their own coupons. "In his tutorials, [he] explained the simple breakdown of barcode creation using the increasingly universal GS1 standard: GS1 codes begin with a 'company prefix' that can be copied from any of the company's products. The next six digits are the 'offer code,' which can be any random number for a counterfeit coupon, followed by the savings amount listed in cents and the required number of item purchases necessary to receive the discount."
coondoggie writes: Researchers at the Defense Advanced Research Projects Agency (DARPA) think online gamers can perform the tedious software verification work typically done by professional coding experts. They were so impressed with their first crowdsourced flaw-detecting games, they announced an new round of five games this week designed for improved playability as well as increased software verification effectiveness. “These games translated players’ actions into program annotations and assisted formal verification experts in generating mathematical proofs to verify the absence of important classes of flaws in software written in the C and Java programming languages. An initial analysis indicates that non-experts playing CSFV games generated hundreds of thousands of annotations,” DARPA stated.

Gizmodo reports: "With the aid of a camera and facial recognition software, the technology was slightly tweaked to instead recognize the official symbols and logos on the uniforms worn by Russian police. And as they approached the billboard featuring the advertisement for Don Giulio Salumeria’s imported Italian goods, it would automatically change to an ad for a Matryoshka doll shop instead."

Four lab workers in the United States and up to 22 overseas have been given precautionary medical treatment. The CDC is investigating the incident and Pentagon spokesman Colonel Steve Warren says, "Out of an abundance of caution, [the Defence Department] has stopped the shipment of this material from its labs pending completion of the investigation."
An anonymous reader writes with a link to some interesting commentary at Help Net Security from Drone Lab CEO Zain Naboulsi about a security issue of a (so far) unusual kind: detecting drones whose masters are bent on malice. That's relevant after the recent drone flight close enough to the White House to spook the Secret Service, and that wasn't the first -- even if no malice was involved. Drones at their most dangerous in that context are small, quiet, and flying through busy, populated spaces, which makes even detecting them tough, never mind defeating them. From the article, which briefly describes pros and cons of various detection methods: Audio detection does NOT work in urban environments - period. Most microphones only listen well at 25 to 50 feet so, because of the ambient noise in the area, any audio detection method would be rendered useless at 1600 Pennsylvania Avenue. It is also too simple for an operator to change the sound signature of a drone by buying different propellers or making other modifications. It doesn't take much to defeat the many weaknesses of audio detection.
Patrick O'Neill writes: Ross Ulbricht has never been tried for murder. But tomorrow, when the convicted Silk Road creator is sentenced to prison, murder will be on the mind of the judge. Despite never filing murder-for-hire charges, New York federal prosecutors have repeatedly pushed for harsh sentencing because they say Ulbricht solicited multiple murders. The judge herself recently referred to Ulbricht's "commission of murders-for-hire" in a letter about the sentencing, painting an even grimmer picture of Ulbricht's sentencing prospects.
