William Herkewitz, writing for Popular Mechanics: Physicists have just built the smallest working engine ever created. It's a heat-powered motor barely larger than the single atom it runs on. Designed and build by a team of experimental physicists led by Johannes at the University of Mainz in Germany, the single atom engine is about as efficient as your car at transforming the changing temperature into mechanical energy. While scientists have previously created several micro-engines consisting of a mere 10,000 particles, Johannes's new engine blows these out of the water by paring down the machine to a singular atom housed in a nano-sized cone of electromagnetic radiation. The project is outlined today in the journal Science. "The engine has the same working principles as the well-known [combustion] car engine," Johannes says. It follows the same four strokes; expanding then cooling, contracting then heating.There's some confusion here. The article says it's a "four-stroke" engine. But as we know, a four-stroke engine consists of an intake stroke, a compression stroke, a power stroke, and an exhaust stroke -- things that the engine in the article doesn't seem to have. The article doesn't mention how a single atom is able to mimic all the effects of a combustion engine. Update: 04/15 18:24 GMT by M :The article appears to have been updated for clarification.

mdsolar quotes a report from Knoxville News Sentinel: An East Tennessean who served as a senior manager in the Tennessee Valley Authority's nuclear program swapped information with one of China's top nuclear power companies in exchange for cash, according to federal court records unsealed Thursday. The U.S. Attorney's Office in Knoxville on Thursday announced an espionage conspiracy indictment against China General Nuclear Power, Chinese nuclear engineer Szuhsiung 'Allen' Ho, and Ho's firm, Energy Technology International. Prosecutors said Ho conspired with the companies to lure nuclear experts in the U.S. into providing information to allow China to develop and produce nuclear material based on American technology and under the radar of the U.S. government. Ho was taken into custody in Atlanta on Thursday afternoon and will be returned to U.S. District Court in Knoxville to face the two-count indictment. The indictment consists of one count of conspiracy to illegally engage and participate in the production and development of special nuclear material outside the U.S. and one count of conspiracy to act in the U.S. as an agent of a foreign government.

An anonymous reader quotes a report from TechCrunch: Google is launching a new service today that allows you to create $35 custom cases for its Nexus 5X, 6 and 6P phones. There are two variations of the Live Cases: one that allows you to pick any photo and print it onto your case, and one that lets you design and print a stylized map with the help of Google Maps. Both variations allow you to select a couple of filters and other styling options to personalize your case even more. Google says there is a programmable shortcut button on the back of the case that will allow you to launch your favorite app with a single click using NFC. Once you've created and ordered your case, Google will also let you download a wallpaper with the same design.

An anonymous reader quotes a report from ZDNet: GoPro quietly announced its Developer Program on Thursday as it looks to incorporate its action sports cameras into third-party products. The GoPro Developer Program provides toolkits, technical information and support to enable companies to add GoPro camera connectivity into their products. There is a camera toolkit for iOS and Android apps to control a GoPro camera and manage media, along with a mechanical toolkit to attach GoPro cameras to third-party products. It announced there are more than 100 companies partnering with GoPro, including brands from BMW, Fisher-Price, and Polar. GoPro showed off potential third-party integration ideas in a video showing a gesture-based camera control system.

Reader holy_calamity writes: Pentagon research agency DARPA has funded the creation of a chip incapable of correct arithmetic, in the hope of making computers better at understanding the real world. A chip that can't guarantee that every calculation is perfect can still get good results on many problems but needs fewer circuits and burns less energy, says Joseph Bates, cofounder and CEO of Singular Computing. The S1 chip can process noisy data like video very efficiently because it doesn't need the extra circuits or operations needed to ensure every mathematical operation is performed perfectly. This summer DARPA will put five prototype computers, each equipped with 16 of the inexact S1 chips, online for researchers to experiment with.

Reader itwbennett writes: An optional Windows patch released Tuesday protects against an attack, dubbed MouseJack that affects wireless mice and keyboards from many manufacturers, including Microsoft and allows attackers to spoof a wireless mouse from up to 100 meters away and send rogue keystrokes instead of clicks to a computer. According to a Microsoft security advisory, the devices affected by this attack are: Sculpt Ergonomic mouse, Sculpt Mobile Mouse, Wireless Mobile Mouse 3000 v2.0, Wireless Mobile Mouse 3500, Wireless Mobile Mouse 4000, Wireless Mouse 1000, Wireless Mouse 2000, Wireless Mouse 5000 and Arc Touch Mouse. But Marc Newlin, one of the researchers who developed the attack said on Twitter that the patch doesn't go far enough and 'injection still works against MS Sculpt Ergonomic Mouse and non-MS mice.'

An anonymous reader writes: Facebook on Wednesday said it has hired Regina Dugan to head a search-and-product-development group considered vital to Facebook's 10-year technology road map. In the past, Dugan helped shape such Google initiatives as Project Tango, Project Ara, and smart fabrics wired with electronics. Dugan will lead Building 8, a new group "focused on building new hardware products to advance our mission of connecting the world," Facebook CEO Mark Zuckerberg said in a comment posted on his Facebook profile today. Zuckerberg's 10-year vision for the company relies on major technological breakthroughs on three main fronts: artificial intelligence, augmented and virtual reality, and bringing Internet access to the 4 billion or so people who don't have it. "I'm excited to have Regina apply DARPA-style breakthrough development at the intersection of science and products to our mission," Zuckerberg said. "This method is characterized by aggressive, fixed timelines, extensive use of partnerships with universities, small and large businesses, and clear objectives for shipping products at scale."

An anonymous reader writes: Peabody Energy Corp filed for U.S. bankruptcy protection on Wednesday after a sharp drop in coal prices left it unable to service debt of $10.1 billion, much of it incurred for an expansion into Australia. As demand for metallurgical coal fell, particularly in China, Peabody's financial woes intensified. The company took a $700 million write-down on its Australian metallurgical coal assets last year. At home, the U.S. shale boom of the past few years made natural gas competitive with thermal coal, and the Obama administration's environmental regulations raised operational costs. Mr. Peabody's coal train might not be hauling away any more of paradise. Peabody, the world's biggest private-sector coal producer, said it expected its mines to continue to operate as usual and said its Australian assets were excluded from the bankruptcy. "This process enables us to strengthen liquidity and reduce debt, build upon the significant operational achievements we've made in recent years and lay the foundation for long-term stability and success in the future," Peabody Chief Executive Officer Glenn Kellow said in a statement.

Reader Mickeycaskill writes: The USB 3.0 Promoter Group, of which HP, Intel and Microsoft are members, has developed authentication protocols for USB-C and will offer free software to detect faulty or malicious cables.This tool will alert users if they are using a non-authenticated cable. It has been suggested that hardware manufacturers could ship devices with an authentication system already installed. It is hoped that the specification will help end a number of recent incidents where sub-standard cables have either ripped off buyers or damaged devices. Most recently, Amazon said it would be adding USB-C cables and adapters that do not comply with standard regulations to its list of prohibited electronics items.

Amazon, on Wednesday, announced the Kindle Oasis, the company's latest addition to its ebook reader offering. The Kindle Oasis offers a range of improvements and changes over the Kindle Paperwhite. Mashable's Lance Ulanoff writes, "[The company has] essentially discarded the previous design in favor of a paper-thin display attached to a somewhat thicker side grip." Elaborating: First of all, the 6-inch screen is close to square. Second of all, it no longer sits in the center of the device. And thirdly, the screen is now an insane 3.4-mm thick. Yes, that is as thin as you think it is. Amazon's Oasis e-reader even marks the return of buttons to the design.As for the specifications, the Kindle Oasis sports a 6-inch display of 300ppi screen resolution, and 10 LEDs for "enhanced page consistency." Instead of "weeks"-long battery life, Amazon is promising "months" of usage on a single charge with Oasis thanks to the cover that ships with it and doubles as a rechargeable battery. It starts at $289.99 (Wi-Fi-only edition and with "advertisements that appear when you wake up the reader"), and goes all the way up to $379 (Wi-Fi + 3G, and no ads).

An anonymous reader writes: The Model S has received several new features and improvements to help it stay relevant with the newer Model X crossover and recently released Model 3 electric vehicles from Tesla. It has a new-look fascia and adaptive LED headlights that hew closely to the design found on the Model X crossover which debuted late last year. In addition to a couple new interior finish choices, the Model S is receiving a version of the Model X's cabin air filtration system as an option, which promises to filter out "99.7 percent of particulate exhaust pollution and effectively all allergens, bacteria and other contaminants from cabin air." The Model S now has a 48-amp charger standard -- up from 40 amps -- which Tesla says will enable faster charging when connected to higher-amp outlets. Tesla's design language is trending toward a grille-less front end, possibly in an effort to squeeze as much aerodynamic efficiency out of the car as possible. What's missing in the update is the rumored 100kWh battery, which would improve the vehicle's range.

Dan Seifert, writing for The Verge: HTC is today formally announcing the 10, its flagship smartphone for 2016. The HTC 10 follows last year's M9 and blends the design of the M series with the A9 that came last fall. HTC says it spent 12 months designing this phone and integrated feedback from its customers throughout the development process. The 10 has everything you might expect from a flagship Android phone in 2016. There's a 5.2-inch, quad HD Super LCD 5 display that HTC says displays 30 percent more color than last year's phone. The screen is covered in Gorilla Glass with curved edges that blend into the phone's metal frame. You'll be able to find out if that's enough for HTC to compete when the phone ships next month for $699. One interesting feature, which separates HTC 10 from many other Android flagship smartphones, is support for AirPlay. The feature enables the smartphone to stream media content to an Apple TV.

An anonymous reader writes: Tesla has recalled 2,700 Model X cars due to a design flaw affecting the vehicle's third row of seats. Specifically, a faulty locking hinge on the last row of seats could potentially cause the seats to collapse forward during a crash. "Despite [15] prior successful tests and no reports of a third row seat slipping in any customer vehicles," Tesla said in an email to affected owners, "we have decided to conduct a voluntary recall as a precautionary measure and will be replacing all affected third row seat backs." Even though the Model X recall is small, it brings to mind the Model 3 and what possible manufacturing issues will pertain to it. BGR writes, "The current number of Model 3 reservations is absolutely staggering and Tesla will have no choice but to get as many Model 3s manufactured and out on the road as soon as humanly possible. So even in a best-case scenario where the rollout of the Model 3 goes swimmingly, Tesla will need to do all it can to ensure that the Model 3s rolling off the line in late 2018 and early 2019 are flawless." Recalling 2,700 vehicles is one thing, but a recall affecting the Model 3 could be a logistical and publicity nightmare.

An anonymous reader writes: Cellebrite, the company many believe helped the FBI crack into the iPhone 5c belonging to a San Bernardino terrorist, is developing a roadside "textalyzer" device to help law enforcement determine whether someone involved in a motor vehicle accident was unlawfully driving while distracted. As reported from Ars Technica: "Under the first-of-its-kind legislation proposed in New York, drivers involved in accidents would have to submit their phone to roadside testing from a textalyzer to determine whether the driver was using a mobile phone ahead of a crash." The textalyzer allegedly would keep conversations, contacts, numbers, photos, and application data private in an effort to get around the Fourth Amendment right to privacy. "Cellebrite has been leading the adoption of field mobile forensics solutions by law enforcement for years, culminating in the formal introduction of our UFED FIELD series product line a year ago," Jim Grady, Cellebrite's CEO, said in a statement. "We look forward to supporting DORCs and law enforcement -- both in New York and nationally to curb distracted driving."

An anonymous reader quotes a report from Digital Trends: Apple's patent, titled "Configurable Force-Sensitive Input Structure for Electronic Devices," was filed in September 2015 and was recently made available to the public on April 7th. It states that this all-in-one input interface consists of a metal contact layer, and a sense layer combined with a drive layer mounted underneath. According to the patent, the sense and drive layers detect a force exerted on the metal contact layer. This is accomplished by using an array of pixels on the sense and drive layers that determine an input location when active pixels are aligned on both layers. The user then gets a response to his or her action thanks to a haptic feedback module and a light guide layer that lights up the "keys" through extremely tiny holes in the metal surface. The components of the force-input sensitive "structure" are enclosed within the device's chassis; thus the only exposed portion is the contact surface itself. In a provided drawing, the illustrated notebook shows four distinct input areas on the surface. However, the patent states that the device can have any number of input areas defined on the contact portion.

An anonymous reader writes: Two Google developers have uploaded an unofficial (for now) draft to the World Wide Web Consortium's Web Incubator Community Group (W3C WICG) that describes a method of interconnecting USB-capable devices to Web pages. The API, called WebUSB, allows device manufacturers to provide special "registry and landing pages" where they can host JavaScript SDKs for their USB-capable devices. Site owners can load these SDKs as iframes inside their websites, and allow a site to access and relay commands (via the iframe to the browser's WebUSB API) to the actual device. To protect privacy and security, the WebUSB API also comes with a CORS-like system that prompts users for access to their devices to avoid abuse and Web-based fingerprinting. The system is also backward compatible with devices created before the standard's approval (if it gets approved).

An anonymous reader shares a report on ZDNet: Security researcher Mike Olsen has warned that some products sold through the Amazon marketplace are harboring a dark secret -- malware. Olsen said in a blog post that while scouring Amazon for a decent set of outdoor surveillance cameras for a friend, he came across a deal for 6 PoE cameras and recording equipment. The seller, Urban Security Group, had generally good reviews and was offering a particular Sony setup on sale. After purchasing the kit, Olsen started setting up the surveillance system, logging into the administrator panel to configure it. [...] Upon investigation, Olsen found that the device was talking to a server with hostname Brenz.pl, which is linked to malware distribution. If the device's firmware links to this domain, malware can be downloaded and installed, potentially leading to unlawful surveillance and data theft.Perhaps the company which made the device didn't realize its source code was compromised. While the aforementioned incident should serve as a reminder to people on why they need to be wary of the product they are purchasing, this isolated occurrence doesn't prove in any way that "plenty" of cameras on Amazon are also infected, as the article and the original blog post are subtly trying to imply.

An anonymous reader writers: A Japanese company is using a 3D printer to generate unique rings shaped like the sound wave of each customer's voice. They generate the digital designs from three-second recordings that customers upload to their web site, and can print out the $300 rings in different colors and sizes, using either silver, gold, or 14K rose paint. 3Ders.org points out that another jeweler can now actually print a ring shaped like a customer's face, while a fashion designer in Sri Lanka teamed up with a 3D printing company for an even romantic product: a wedding dress. "The ultimate result of this was a super excited bride that not only had an especially memorable day but walked down the aisle with the only dress of its kind in the country."

SCHAFT, one of eight robotic companies in the Alphabet/Google X research facility, has unveiled a new armless bipedal robot which can climb stairs and carry up to 132 pounds, reports i-programmer.info. The one-meter tall robot "is essentially a pair of almost entirely straight legs which pivot from the top," and the robot can walk on snow or uneven surfaces, even staying upright while researchers tried to trip it. The as-yet-unnamed robot was introduced during a keynote address at the New Economic Summit in Tokyo given by Android Inc. co-founder Andy Rubin (who left Google 18 months ago). A SCHAFT spokesperson later added that the presentation wasn't a product announcement. "The team was simply delighted to have a chance to show their latest progress."

More than $8 billion a year is spent on diversity training which a Harvard professor believes is largely ineffective. So later this year the NFL will also try using new VR scenarios from Stanford's Virtual Human Interaction Lab. "We want to be known as the best place to work," says NFL vice president Troy Vincent," while Dropbox's head of diversity says she's also had conversations about eliminating bias in job interviews by conducting "blind" interviews using avatars. The Stanford lab's scenarios place users in unsettling situations -- for example, angry harassment by white avatars while the user's avatar is black. "I'm not saying, 'Put on a VR goggle and you've solved racism'," says the Stanford lab's director. "But I'm optimistic it can help."
