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.

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.

itwbennett tips news that Uber has amended its privacy policy, making it much simpler to read and understand. But the policy also includes changes to what data Uber collects about its riders. Beginning July 15th, the Uber phone app will keep track of a rider's location while it's running in the background. Uber says riders will be able to opt out of this tracking. The policy changes also allow for advertising using the rider's contact list: "for example the ability to send special offers to riders' friends or family." The revision of Uber's privacy policy followed complaints at the end of last year that the company was overstepping its bounds.

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."

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."

Why Detecting Drones Is a Tough Gig 222

Posted by timothy
from the if-you-see-something-it's-too-late dept.
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.

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.

jones_supa writes: USB Type-C connection is showing up in more and more devices, and Google is rolling support for the interface in its Android M operating system. The most significant additions relate to the USB Power Delivery spec. Charging will now work in both directions. That effectively means that Type-C devices can be used as external batteries for other devices. Android M is also finally introducing a feature that musicmakers have been long asking for: MIDI support. This builds on some of the audio features Google introduced in Android 5, including reduction in latency, multichannel audio stream mixing, and support for USB microphones, amplifiers, speakers, and other accessories. As others have written, music and media creation apps are much more prevalent in iOS than they are in Android, and Google hopes turning that around.

from the micro-management dept.
William Robinson writes: Under the direction of Latha Venkataraman, associate professor of applied physics at Columbia Engineering, researchers have designed a new technique to create a single-molecule diode, that has rectification ratio as high as 250, and 'ON' current as high as 0.1 microamps. The idea of creating a single-molecule diode was suggested by Arieh Aviram and Mark Ratner who theorized in 1974, which has been the 'holy grail' of molecular electronics ever since its inception to achieve further miniaturization, because single molecule represent the limit of miniaturization.
