An anonymous reader quotes VentureBeat: Native honeybees, one of the most prolific pollinators in the animal kingdom, are dying off at an unprecedented rate from Colony Collapse Disorder and threatening an ecosystem service worth about $15 billion. Supported by the National Science Foundation, the RoboBees project looks to minimize the loss of this critical resource with new microbots that can mimic the pollinating role of a honeybee... In a remarkable display of biomimicry, scientists have developed a flight-capable robot that's just half the size of a paperclip and weighs in at one tenth of a gram... The RoboBees project pushes the boundaries of research in a variety of fields, from micromanufacturing to energy storage and even the computer algorithms that control the robots by the swarm...

While the effect of a single robot might be miniscule, a coordinated group of hundreds, thousands, or millions of RoboBees could perform a host of unprecedented tasks. Aside from pollinating plants for agricultural purposes, the RoboBees could coordinate to digitally map terrain, monitor weather conditions, and even assist in relief efforts after a disaster, through data collection. While RoboBees are only intended as a stopgap measure for honeybee loss, the potential applications of the technology have the world holding its breath for the next breakthrough.

"It's not about an undo button," writes Slashdot reader marcle, sharing an article by a senior member of the technical staff at Sandia National Laboratories who's studying advanced technologies for computation. "Just reading this story bends my mind." From IEEE Spectrum: [F]or several decades now, we have known that it's possible in principle to carry out any desired computation without losing information -- that is, in such a way that the computation could always be reversed to recover its earlier state. This idea of reversible computing goes to the very heart of thermodynamics and information theory, and indeed it is the only possible way within the laws of physics that we might be able to keep improving the cost and energy efficiency of general-purpose computing far into the future... Today's computers rely on erasing information all the time -- so much so that every single active logic gate in conventional designs destructively overwrites its previous output on every clock cycle, wasting the associated energy. A conventional computer is, essentially, an expensive electric heater that happens to perform a small amount of computation as a side effect...

[I]t's really hard to engineer a system that does something computationally interesting without inadvertently incurring a significant amount of entropy increase with each operation. But technology has improved, and the need to minimize energy use is now acute... In 2004 Krishna Natarajan (a student I was advising at the University of Florida) and I showed in detailed simulations that a new and simplified family of circuits for reversible computing called two-level adiabatic logic, or 2LAL, could dissipate as little as 1 eV of energy per transistor per cycle -- about 0.001 percent of the energy normally used by logic signals in that generation of CMOS. Still, a practical reversible computer has yet to be built using this or other approaches.
The article predicts "if we decide to blaze this new trail of reversible computing, we may continue to find ways to keep improving computation far into the future. Physics knows no upper limit on the amount of reversible computation that can be performed using a fixed amount of energy."

But it also predicts that "conventional semiconductor technology could grind to a halt soon. And if it does, the industry could stagnate... Even a quantum-computing breakthrough would only help to significantly speed up a few highly specialized classes of computations, not computing in general."

intellitech shares a report from Engadget: For those of you who miss the iPhone headphone jack, you're definitely not alone. But Strange Parts creator Scotty Allen missed it so much that he decided to add one to his iPhone 7. He just posted a video of the project's entire saga, with all of its many ups and downs, and in the end he holds what he set out to create -- a current generation iPhone with a fully functional headphone jack. It turns out, real courage is adding the headphone jack back to the iPhone. The project took around 17 weeks to complete and throughout it Allen spent thousands of dollars on parts including multiple iPhones and screens and handfuls of lightning to headphone adaptors. Along the way, Allen bought a printer, a nice microscope and fancy tweezers. He had to design his own circuit boards, have a company manufacture multiple iterations of flexible circuit boards and at one point early on had to consult with a chip dealer that a friend hooked him up with.

The final product works by using a lightning to headphone adaptor that's incorporated into the internal structure of the phone. However, because the headphone jack is powered via the phone's lightning jack with a circuit board switching between the two depending on whether headphones or a charger are plugged into the phone, you can't actually listen to music and charge the phone at the same time.

ugen shares a report from CNBC: Artificial Intelligence (AI) can now accurately identify a person's sexual orientation by analyzing photos of their face, according to new research. The Stanford University study, which is set to be published in the Journal of Personality and Social Psychology and was first reported in The Economist, found that machines had a far superior "gaydar" when compared to humans. Slashdot reader randomlygeneratename adds: Researchers built classifiers trained on photos from dating websites to predict the sexual orientation of users. The best classifier used logistic regression over features extracted from a VGG-Face conv-net. The latter was done to prevent overfitting to background, non-facial information. Classical facial feature extraction also worked with a slight drop in accuracy. From multiple photos, they achieved an accuracy of 91% for men and 83% for women (and 81% / 71% for a single photo). Humans were only able to get 61% and 54%, respectively. One caveat is the paper mentions it only used Caucasian faces. The paper went on to discuss how this capability can be an invasion of privacy, and conjectured that other types of personal information might be detectable from photos. The source paper can be found here.

gubol123 shares a report from The Economic Times: Six leading car makers are eyeing the government's plan to buy 10,000 electric vehicles while policy makers are considering generous fiscal incentives to make their capital and running cost cheaper than petrol cars within five years. Broadly, the aim is to put on roads one million electric three-wheelers and 10,000 electric city buses by mid-2019 and make India the world leader in at least some segments of the market as the country strives to shift entirely to battery-powered transportation by 2030. In six to eight months, 10,000 e-vehicles are expected to be running in the national capital region. The tender to buy 10,000 e-vehicles has already attracted Tata Motors, Hyundai, Nissan, Renault, Maruti Suzuki and Mahindra & Mahindra, and would be quickly followed by a dramatic scaling up of the e-vehicles program. The tender would be awarded by the end of this month and cars would start rolling in by mid-November.

An anonymous reader quotes a report from The Verge: The Note brand is still going strong despite Samsung recalling and discontinuing Note 7 devices last year for battery explosions. The company today announced that more customers in the U.S. have preordered the Note 8 than any other Notes it has ever sold in previous years during the same time period. Note 8 preorders went live on August 24th and the device is one of Samsung's most expensive smartphones to date, starting at $930. It's unapologetically pricey, though Samsung did attempt to offset that price tag with some presale offers. Samsung did not specify exactly how many Note 8 preorders it has received so far, but judging by how popular Note 7s were last year before everything went down, it seems that little has deterred Note fans from upgrading -- not even the price tag.

An anonymous reader quotes a report from Reuters: The United Nations' aviation agency is backing the creation of a single global drone registry, as part of broader efforts to come up with common rules for flying and tracking unmanned aircraft. While the International Civil Aviation Organization cannot impose regulations on countries, ICAO has proposed formation of the registry during a Montreal symposium this month to make data accessible in real time, said Stephen Creamer, director of ICAO's air navigation bureau. The single registry would eschew multiple databases in favor of a one-stop-shop that would allow law enforcement to remotely identify and track unmanned aircraft, along with their operator and owner. It's not yet clear who would operate such a database, although ICAO could possibly fill that role. The proposal, however, could face push back from users, after hobbyists successfully challenged the creation of a U.S. drone registry by the Federal Aviation Administration in court earlier this year.

Google announced in a blog post today that the Google Drive app for desktop will be shut down. The Verge reports: Support will be cut off on December 11th and the app will shut down completely on March 12th, 2018. Users who are still running the Drive app will start seeing notifications in October that it's "going away," and the company will steer customers towards one of two replacements depending on whether they're a consumer or business user. Google Drive the service isn't going anywhere. You can still access it from the web, smartphone apps, and either of the software options mentioned below. Google now has two fairly new software tools for backing up your data and/or accessing files in the cloud. There's Backup and Sync, the all-encompassing consumer app that replaces both the standalone Google Drive and Google Photos Uploader apps. It offers essentially the same functionality as Drive and works much the same way. And on the enterprise side, Google has rolled out Drive File Streamer, which saves space on your local drive while providing access to "all of your Google Drive files on demand, directly from your computer."

Yoko Kubota, Tripp Mickle, and Takashi Mochizuki, reporting for WSJ: Apple's new iPhone, which is expected to be unveiled Tuesday, was plagued by production glitches early in the manufacturing process this summer, according to people familiar with the situation, which could result in extended supply shortfalls and shipping delays when customers start ordering the device later this month (alternative source). New iPhones are typically in short supply when first released. But if shortfalls of the new phone extend beyond the initial sales period, which is expected to begin September 22, they could weaken analysts' and investors' projections for sales in the crucial holiday period. The production glitches led to a setback of about a month in the manufacturing timetable. Foxconn, the Apple contractor that assembles iPhones, has been ramping up production at its manufacturing complex in Zhengzhou, China. The company is paying bonuses to employees who can help bring new hires on board at its Zhengzhou plant, which Foxconn said in June employs about 250,000 people.

Numerous Slashdot readers are reporting that they are facing issues access Google Drive, the productivity suite from the Mountain View-based company. Google's dashboard confirms that Drive is facing outage. Third-party web monitoring tool DownDetector also reports thousands of similar complaints from users. The company said, "Google Drive service has already been restored for some users, and we expect a resolution for all users in the near future. Please note this time frame is an estimate and may change. Google Drive is not loading files and results in a failures for a subset of users."

Update: 09/07 17:13 GMT: Google says it has resolved the issue.

An anonymous reader quotes a report from Ars Technica: Google's got a hot new ride. The company has a new Street View car with updated cameras, and -- surprisingly -- a set of Lidar (Light, Detection and Ranging) cans! Google doesn't have anything up officially about this, but Wired has the scoop on the new vehicles. The camera system upgrade -- the first in eight years -- greatly improves the image quality while simplifying the rig. In the main ball, Google is down from 15 cameras to seven, making the whole package a lot smaller. These 20MP cameras are aimed all around the car, and the pictures they take are stitched together into a spherical image for Google Maps. There's more to the cars than just the ball though: there are also a pair of "HD" cameras that face directly left and right. These are dedicated to reading street signs, business names, and even posted store hours; those images are funneled to Google's cloud computers for visual processing. The end result of the new cameras will be prettier Street View shots, with higher resolution, better colors, and fewer stitching errors. The better images should also result in more data for Google's various visual feature-detection algorithms.

Wired's report focuses almost entirely on the new cameras, but I think the the most interesting additions are the two LIDAR pucks that hang just below the camera ball. These are the ubiquitous Velodyne VLP-16 "Puck" sensors, allowing the to car "see" in 3D in 360 degrees. These $8,000 Lidar sensors are most commonly used in autonomous car prototypes, so to see them on a Street View car is unexpected. Don't expect the Street View cars to start driving themselves anytime soon -- as Google Street View's Technical Program Manager Steve Silverman says in Wired's video, the Lidar sensors "are used to position us in the world."

An anonymous reader quotes a report from Fortune: Hackers have been burrowing their way inside the critical infrastructure of energy and other companies in the U.S. and elsewhere, warns cybersecurity giant Symantec. In a new report, Symantec claims that the threat of cyberattack-induced power outages in the west has elevated from a theoretical concern to a legitimate one in recent months. "We're talking about activity we're seeing on actual operational networks that control the actual power grid," Eric Chien, technical director of security technology and response at Symantec, told Fortune on a call. Reports surfaced over the summer of hackers targeting staff at nuclear energy facilities with phishing attacks, designed to steal login credentials or install malware on machines. The extent of the campaign as well as the question of whether the attackers had breached operational IT networks, rather than merely administrative ones, was unclear at the time. Symantec is now erasing all doubt. "There are no more technical hurdles for them to cause some sort of disruption," Chien said of the hackers. "All that's left is really motivation." Symantec detailed its findings in a report released Wednesday morning. The paper tracks the exploits of a hacker group that Symantec has dubbed DragonFly 2.0, an outfit that the company says it has linked to an earlier series of attacks perpetrated between 2011 and 2014 by a group it dubbed DragonFly.

An anonymous reader shares a report: Researchers in Australia have found a new way to build quantum computers which they say would make them dramatically easier and cheaper to produce at scale. Quantum computers promise to harness the strange ability of subatomic particles to exist in more than one state at a time to solve problems that are too complex or time-consuming for existing computers. The team from the University of New South Wales say they have invented a new chip design based on a new type of quantum bit, the basic unit of information in a quantum computer, known as a qubit. The new design would allow for a silicon quantum processor to overcome two limitations of existing designs: the need for atoms to be placed precisely, and allowing them to be placed further apart and still be coupled. Crucially, says project leader Andrea Mello, this so-called "flip-flop qubit" means the chips can be produced using the same device technology as existing computer chips.

An anonymous reader writes from a report via Bleeping Computer: An attacker can downgrade components of the Android TrustZone technology -- a secure section of smartphone CPUs -- to older versions that feature known vulnerabilities. The attacker can then use previously published exploit code to attack up-to-date Android OS versions. The research team proved their attack in tests on devices running the ARM TrustZone technology, such as Samsung Galaxy S7, Huawei Mate 9, Google Nexus 5, and Google Nexus 6. They replaced updated versions of the Widevine trustlet with an older version that was vulnerable to CVE-2015-6639, a vulnerability in Android's Qualcomm Secure Execution Environment (QSEE) -- Qualcomm's name for its ARM TrustZone version that runs on Qualcomm chips. This vulnerability allows attackers root level access to the TrustZone OS, which indirectly grants the attack control over the entire phone. The research paper is available here, and one of the researcher's authors explains the attack chain in an interview here.

New submitter Provocateur writes: Lenovo will be marking the 25th anniversary of IBM's well known notebook with the Thinkpad 25. Andrew Orlowski writes via The Register: "The long-awaited 'retro' Thinkpad will be based on the guts of a contemporary T470 laptop, Lenovo's business workhorse, according to a German certification site. Lenovo inherited IBM's notebook brand 12 years ago, and with it a design classic. However, in 2012 Lenovo saw fit to 'modernize' the iconic keyboard, along with other unwelcome changes. This didn't meet with approval from some stalwarts, who clung to the superior X220 and T420 lines, the last that you could buy with the 7 row QWERTY. Two years ago Lenovo's design chief Dave Hill acknowledged that some people 'would stand in line' for the classic version. In June, Hill confirmed that for the Thinkpad's 25th anniversary this year a retro edition would indeed be produced, which Hill promised 'will embody many of the things people asked for.'

The German certification site has found the 'Thinkpad 25' variant described as a Thinkpad T470 here (hat-tip to NoteBook Check). A Chinese notebook forum has a picture purporting to be the Thinkpad 25."
