An anonymous reader shares new work that could allow us to generate electricity using supercritical carbon dioxide. Ars Technica reports: The researchers involved in the new work, a large U.S.-based collaboration, focus on a composite material: tungsten and zirconium carbide. These have extremely high melting points: 3,700K for both materials. Both of them conduct heat extremely well, and neither of them expands or softens much under these conditions, meaning they would hold up better to the mechanical stresses. While the stats are impressive, the amazing part of this is how the material is fabricated. The researchers started with tungsten carbide, a ceramic that can be formed into a porous material simply by pouring it as a powder into a mold and heating it. At this point, the ceramic can be further machined to produce a final shape. Once in its final form, the ceramic was placed in a bath of a molten mixture of copper and zirconium. The molten mixture filled the pores, and the zirconium reacted with the tungsten carbide, replacing the tungsten. The copper in the molten material formed a thin film on the surface of the solid.

The tungsten then filled the pores in the resulting material, allowing it to retain the same shape and size despite the chemical changes. The zircon carbide ends up providing the material with a stiffness even at high temperatures, while the tungsten is flexible enough to keep the whole thing from being brittle. And the whole thing conducted heat better than the metals currently in use. The remaining issue is that, at the conditions involved in solar thermal plants, the copper on the material would react with the carbon dioxide, forming a copper oxide and releasing carbon monoxide. But the researchers determined that adding a small amount of carbon monoxide to the supercritical CO2 would suppress this reaction, something that they confirmed experimentally. Because the material holds up to these conditions so much better than the metals currently in use, it's possible to use much less of it to build a heat exchanger. This is great economically (since you need fewer raw materials), and the small size increases the power density and efficiency of the heat exchanger.

MojoKid writes: Intel lifted the embargo veil today on performance results for its new Core i9-9900K 9th Gen 8-core processor. Intel claims the chip is "the best CPU for gaming" due to its high clock speeds and monolithic 8-core/16-thread design that has beefier cache memory (now 16MB). The chip also has 16-lanes of on-chip PCIe connectivity, official support for dual-channel memory up to DDR4-2666, and a 95 watt TDP. Intel also introduced two other 9th Gen chips today. Intel's Core i7-9700K is also an 8-core processor, but lacks HyperThreading, is clocked slightly lower, and has 4MB of smart cache disabled (12MB total). The Core i5-9600K takes things down to 6 cores / 6 threads, with a higher base clock, but lower boost clock and only 9MB of smart cache. In benchmark testing, the high-end Core i9-9900K's combination of Intel's latest microarchitecture and boost frequencies of up to 5GHz resulted in the best single-threaded performance seen from a desktop processor to date. The chip's 8-cores and 16-threads, larger cache, and higher clocks also resulted in some excellent multi-threaded scores that came close to catching some of Intel's many-core Core X HEDT processors in a few tests. The Core i9-9900K is a very fast processor, but it is also priced as such at $488 in 1KU quantities. That makes it about $185 to $225 pricier than AMD's Ryzen 7 2700X, which is currently selling for about $304 and performs within 3% to 12% of Intel's 8-core chip, depending on workload type.

Steam VR is introducing a new feature called "Motion Smoothing" that will give PCs with low-end hardware the power to deliver VR experiences more smoothly. "It functions like Motion Smoothing for TV and Asynchronous Spacewarp for Oculus devices, which are frame-rate smoothing techniques that generate synthetic frames between two real ones in order to avoid a stuttery experience," notes Engadget. From the report: When Steam VR determines that an experience is lagging or dropping frames, Motion Smoothing automatically kicks in. It drops an app's framerate from 90FPS to 45FPS and generates a synthetic frame for every real one to mimic real 90FPS. If things get especially bad, it can generate two to three frames for every real one instead. Steam explains that the feature "dramatically [lowers] the performance requirements," allowing PCs with lower end hardware to "produce smooth frames." Take note, however, that the feature will not work with the Oculus Rift or with Windows Mixed Reality headsets. You can only take advantage of it if you have an HTC Vive or a Vive Pro, and if you're running Windows 10 -- all you need to do is right-click on Steam VR and select beta under Tools in Library.

Like fingerprints, no 3D printer is exactly the same. That's the takeaway from a new University at Buffalo-led study that describes what's believed to be the first accurate method for tracing a 3D-printed object to the machine it came from. From the study: The advancement, which the research team calls "PrinTracker," could ultimately help law enforcement and intelligence agencies track the origin of 3D-printed guns, counterfeit products and other goods. "3D printing has many wonderful uses, but it's also a counterfeiter's dream. Even more concerning, it has the potential to make firearms more readily available to people who are not allowed to possess them," says the study's lead author Wenyao Xu, PhD, associate professor of computer science and engineering in UB's School of Engineering and Applied Sciences.

[...] To understand the method, it's helpful to know how 3D printers work. Like a common inkjet printer, 3D printers move back-and-forth while "printing" an object. Instead of ink, a nozzle discharges a filament, such as plastic, in layers until a three-dimensional object forms. Each layer of a 3D-printed object contains tiny wrinkles -- usually measured in submillimeters -- called in-fill patterns. These patterns are supposed to be uniform. However, the printer's model type, filament, nozzle size and other factors cause slight imperfections in the patterns. The result is an object that does not match its design plan.

Security researchers have found flaws in four popular connected storage drives that they say could let hackers access a user's private and sensitive data. From a report: The researchers Paulos Yibelo and Daniel Eshetu said the software running on three of the devices they tested -- NetGear Stora, Seagate Home and Medion LifeCloud -- can allow an attacker to remotely read, change and delete data without requiring a password. Yibelo, who shared the research with TechCrunch this week and posted the findings Friday, said that many other devices may be at risk.

The software, Hipserv, built by tech company Axentra, was largely to blame for three of the four flaws they found. Hipserv is Linux-based, and uses several web technologies -- including PHP -- to power the web interface. But the researchers found that bugs could let them read files on the drive without any authentication. It also meant they could run any command they wanted as "root" -- the built-in user account with the highest level of access -- making the data on the device vulnerable to prying eyes or destruction.

An anonymous reader shares an excerpt from The Economist: Events about making new things are ten a penny. Less common are events about keeping things as good as new. Maintenance lacks the glamour of innovation. It is mostly noticed in its absence -- the tear in a shirt, the mould on a ceiling, the spluttering of an engine. Not long ago David Edgerton of Imperial College London, who also spoke at the festival, drove across the bridge in Genoa that collapsed in August, killing 43 people (pictured). 'We're encouraged to pride ourselves on all being innovators and entrepreneurs,' he said. Maintenance is often dismissed as mere drudgery. But in fact, as he pointed out, repairing things is often trickier than making them.

It is also more difficult for economists to measure. The discipline's most prominent statistic, GDP, is gross (as opposed to net) because it leaves out the cost of wear and tear. To calculate these costs, statisticians must estimate the lifespan of a country's assets and make assumptions about the way they deteriorate. [...] And how much do economies spend fighting decay? No one knows, partly because most maintenance is performed in-house, not purchased on the market. The best numbers are collected by Canada, where firms spent 3.3% of GDP on repairs in 2016, more than twice as much as the country spends on research and development. In closing, the report mentions the tyrannies of the ancient East where people were forced to maintain fragile irrigation systems. "In those societies, to repair was to repress," the report says. "But some people today have the opposite concern. They see maintenance and repair as a right they are in danger of losing to companies that hoard spare parts and information too jealously."

In a paper published Thursday in the journal Science, Dr. Sergey Bravyi and his team reveal that they've developed a mathematical proof which, in specific cases, illustrates the quantum algorithm's inherent computational advantages over classical. Engadget reports: "It's good to know, because results like this become parts of algorithms," Bob Sutor, vice president of IBM Q Strategy and Ecosystem, told Engadget. "They become part of decisions about how people will start to attack problems. Where will they try classical techniques? Where will they try quantum techniques? How will those interplay? How will they work back and forth together?" What's more, the proof shows that, in these cases, the quantum algorithm can solve the problem in a fixed number of steps, regardless of how many inputs are added. With a classical computer, the more inputs you add, the more steps it needs to take in order to solve. Such are the advantages of parallel processing.

"The main point of this paper is not that somehow we discover some incredibly important quantum algorithm, or some practical, interesting problem," Bravyi told Engadget. "We ask if we can separate a constant depth [between] quantum and classical algorithms. As we increase the problem size, the runtime of the quantum algorithm remains constant, but the total number of operations grows." As Bravyi points out, this new proof doesn't, in and of itself, solve any existing computational issues. Instead, "it gives us insight into what makes a quantum computers more powerful," he continued. "And hopefully in the future it will lead to more practical, useful algorithms."

New advances are taking automation to the highest end of human endeavors, offering scientists a shot at some of the most intractable problems that have confounded them -- and along the way tipping a global balance to give upstarts like China a more level playing field in the lab. From a report: A combination of artificial intelligence and nimble robots are allowing scientists to do more, and be faster, than they ever could with mere human hands and brains. "We're in the middle of a paradigm shift, a time when the choice of experiments and the execution of experiments are not really things that people do," says Bob Murphy, the head of the computational biology department at Carnegie Mellon University.

Automated science is "moving the role of the scientist higher and higher up the food chain," says Murphy. Researchers are focusing their efforts on big-picture problem-solving rather than the nitty-gritty of running experiments. He says it will also allow scientists to take on more problems at once -- and solve big, lingering ones that are too complex to tackle right now. Starting next year, Murphy's department will offer students a master's degree in automated science, the university announced last week.

At an event in New York City today, the Seoul, South Korea electronics giant took the wraps off of the Galaxy Book 2, a Windows ultraportable powered by Qualcomm's Snapdragon 850 chip. From a report: The only catch? It runs Windows 10 S, a slimmed-down version of Microsoft's operating system that can only run applications from the Windows Store -- specifically Universal Windows Platform (UWP) apps and Win32 apps that Microsoft has explicitly approved (including, but not limited to, Microsoft Office). You can upgrade to Windows 10 for free, of course, but it's an emulated experience. But if that doesn't bother you, you'll be able to pick up a Book 2 at AT&T, Microsoft, and Samsung stores online for $999.99 starting November 2, 2018. It'll hit brick and mortar at AT&T, Sprint and Verizon later in the month.

The Book2 -- which measures 11.32 x 7.89 x 30 inches and weighs in at 1.75 pounds -- looks sort of like Microsoft's Surface. Its gorgeous 12-inch 2,160 by 1,440-pixel AMOLED display (216 pixels per inch) is fully compatible with Samsung's S Pen stylus, which comes bundled in the box (along with a detachable keyboard that attaches magnetically to the bottom bezel), allowing you to scribble notes and mark up documents easily. The screen's paired with stereo speakers tuned by Samsung subsidiary AKG Acoustic with support for Dolby Atmos, a premium audio format for multichannel surround sound setups, and there's two cameras onboard: a front-facing 5-megapixel camera on tap and an 8-megapixel camera on the rear. Under the hood is the aforementioned Qualcomm Snapdragon 850 system-on-chip paired with 4GB of RAM, comprising four high-performance processor cores running at 2.96 GHz and four power-efficient cores clocked at 1.7 GHz.

An anonymous reader quotes a report from Bloomberg: Although the century-old technology has disappeared from most people's daily view, magnetic tape lives on as the preferred medium for safely archiving critical cloud data in case, say, a software bug deletes thousands of Gmail messages, or a natural disaster wipes out some hard drives. The world's electronic financial, health, and scientific records, collected on state-of-the-art cloud servers belonging to Amazon.com, Microsoft, Google, and others, are also typically recorded on tape around the same time they are created. Usually the companies keep one copy of each tape on-site, in a massive vault, and send a second copy to somebody like Iron Mountain. Unfortunately for the big tech companies, the number of tape manufacturers has shrunk over the past three years from six to just two -- Sony and Fujifilm -- and each seems to think that's still one too many.

The Japanese companies have said the tape business is a mere rounding error as far as they're concerned, but each has spent millions of dollars arguing before the U.S. International Trade Commission to try to ban the other from importing tapes to America. [...] The tech industry worries that if Sony or Fujifilm knocks the other out of the U.S., the winner will hike prices, meaning higher costs for the big cloud providers; for old-line storage makers, including IBM, HPE, and Quantum; and, ultimately, for all those companies' customers. [...] Although Sony and Fujifilm have each assured the trade commission that they could fill the gap if their rival's products were shut out of the U.S., the need for storage continues to grow well beyond old conceptions. Construction is slated to begin as soon as next year on the Square Kilometer Array, a radio telescope with thousands of antennas in South Africa and Australia meant to detect signals emitted more than 13 billion years ago. It's been estimated the project could generate an exabyte (1 billion gigabytes) of raw data every day, the equivalent of 300 times the material in the U.S. Library of Congress and a huge storage headache all by itself.

An anonymous reader quotes a report from Engadget: [N]ew research published in ACS Applied Energy Materials shows that it's possible to 3D-print lithium-ion batteries into whatever shape you need. The problem that has stood in the way of 3D-printed lithium-ion batteries (at least, until now) is that the polymers traditionally used in this kind of printing aren't ionic conductors. The goal was to find a way to print custom-sized lithium-ion batteries in a cost-effective way using a regular, widely available 3D printer. In order to make the batteries conductive, the team led by Christopher Reyes and Benjamin Wiley infused the polylactic acid (PLA) usually used in 3D printing with an electrolyte solution. The researchers also incorporated graphene and carbon nanotubes into the design of the case to help increase conductivity. After these design modifications, the team was able to 3D print an LED bracelet, complete with a custom-sized lithium-ion battery. The battery was only able to power the bracelet for about 60 seconds, but the researchers have ideas for how to improve the capacity. For those interested, Engadget has a short video on the subject.

An anonymous reader quotes a report from Bloomberg: Apple on Wednesday began allowing users in the U.S. to download a copy of all of the data that they have stored with the company from a single online portal. U.S. users will be able to download data such as all of their address book contacts, calendar appointments, music streaming preferences and details about past Apple product repairs. Previously, customers could get their data by contacting Apple directly. In May, when Apple first launched the online privacy portal, it only allowed U.S. users to either correct their data or delete their Apple accounts.

An anonymous reader shares a report: Sellers have been modifying lower end NVIDIA graphics cards and selling them more powerful cards online. In a recent version of the GPU-Z graphics card information utility, TechPowerUp has added the ability to now detect these fake NVIDIA cards. This new feature allows buyers of cards to detect if the card is actually a relabled NVIDIA G84, G86, G92, G94, G96, GT215, GT216, GT218, GF108, GF106, GF114, GF116, GF119, or GK106 GPU by displaying an exclamation point where the NVIDIA logo would normally appear and also prepends the string "[FAKE]" before the card's name.

bricko shares a report from Bloomberg with the caption, "Making batteries is a mess": Beneath the hoods of millions of the clean electric cars rolling onto the world's roads in the next few years will be a dirty battery. Every major carmaker has plans for electric vehicles to cut greenhouse gas emissions, yet their manufacturers are, by and large, making lithium-ion batteries in places with some of the most polluting grids in the world. By 2021, capacity will exist to build batteries for more than 10 million cars running on 60 kilowatt-hour packs, according to data of Bloomberg NEF. Most supply will come from places like China, Thailand, Germany and Poland that rely on non-renewable sources like coal for electricity.

An electric vehicle in Germany would take more than 10 years to break even with an efficient combustion engine's emissions. "We're facing a bow wave of additional CO2 emissions," said Andreas Radics, a managing partner at Munich-based automotive consultancy Berylls Strategy Advisors, which argues that for now, drivers in Germany or Poland may still be better off with an efficient diesel engine. The findings, among the more bearish ones around, show that while electric cars are emission-free on the road, they still discharge a lot of the carbon-dioxide that conventional cars do. Just to build each car battery -- weighing upwards of 500 kilograms (1,100 pounds) in size for sport-utility vehicles -- would emit up to 74 percent more C02 than producing an efficient conventional car if it's made in a factory powered by fossil fuels in a place like Germany, according to Berylls' findings. Yet regulators haven't set out clear guidelines on acceptable carbon emissions over the life cycle of electric cars, even as the likes of China, France and the U.K. move toward outright bans of combustion engines. It all has to do with manufacturing. According to estimates of Mercedes-Benz's electric-drive system integration department, manufacturing an electric car pumps out "significantly" more climate-warming gases than a conventional car, which releases only 20 percent of its lifetime CO2 at this stage. "Just switching to renewable energy for manufacturing would slash emissions by 65 percent, according to Transport & Environment," reports Bloomberg. "In Norway, where hydro-electric energy powers practically the entire grid, the Berylls study showed electric cars generate nearly 60 percent less CO2 over their lifetime, compared with even the most efficient fuel-powered vehicles."

A couple months ago, it was reported that the dearly departed mobile brand known as Palm would be making a comeback. That day has finally come. Yesterday, Palm announced The Palm, a credit card-sized Android smartphone that's supposed to act as a second phone. Droid Life reports: The Palm, which is its name, is a mini-phone with a 3.3-inch HD display that's about the size of a credit card, so it should fit nicely in your palm. It could be put on a chain or tossed in a small pocket or tucked just about anywhere, thanks to that small size. It's still a mostly fully-featured smartphone, though, with cameras and access to Android apps and your Verizon phone number and texts.

The idea here is that you have a normal phone with powerful processor and big screen that you use most of the time. But when you want to disconnect some, while not being fully disconnected, you could grab Palm instead of your other phone. It uses Verizon's NumberSync to bring your existing phone number with you, just like you would if you had an LTE smartwatch or other LTE equipped device. Some of the specs of this Verizon-exclusive phone include a Snapdragon 435 processor with 3GB RAM, 32GB storage, 12MP rear and 8MP front cameras, 800mAh battery, IP68 water and dust resistance, and Android 8.1. As Kellen notes, "It does cost $350, which is a lot for a faux phone..."

We've already seen a number of gadget fans perplexed by this device. Digital Trends goes as far as calling it "the stupidest product of the year."

Google Maps is adding a new feature that will let you search for charging stations and provide you with useful information about that station. The feature is rolling out today and will be available on both Android and iOS. Engadget reports: Just search for "EV charging stations" or "EV charging," and Google Maps will locate those nearby. It will also tell you what types of ports are available, how many there are as well as the station's charging speeds, and businesses with charging stations will now have a link that will lead you to more information about their setup. Additionally, you'll be able to see what other users thought of the station, as Google Maps will bring up user-posted photos, ratings and reviews. Google Maps will include information about charging stations from Tesla and Chargepoint worldwide. In the US, it will also source info about SemaConnect, EVgo and Blink stations. UK users will have access to Chargemaster and Pod Point stations, while Australia and New Zealand EV drivers will see info on Chargefox stations. Unfortunately, you won't be able to tell if individual charging stations are occupied. Also, Google doesn't have Electrify America, a Volkswagen subsidiary that's building a nationwide network of fast-charging stations with universal technology.

Huawei's new Mate 20 Pro has a massive screen, three cameras on the back and a fingerprint scanner embedded in the display. From a report: The new top-end phone from the Chinese firm aims to secure its place at the top of the market alongside Samsung, having recently beaten Apple to become the second-largest smartphone manufacturer in August. The Mate 20 Pro follows Huawei's tried and trusted format for its Mate series: a huge 6.39in QHD+ OLED screen, big 4,200mAh battery and powerful new Huawei Kirin 980 processor -- Huawei's first to be produced at 7 nanometres, matching Apple's latest A12 chip in the 2018 iPhones.

New for this year is an infrared 3D facial recognition system, similar to that used by Apple for its Face ID in the iPhone XS, and one of the first fingerprint scanners embedded in the screen that is widely available in the UK, removing the need for a fingerprint scanner on the back or a chin on the front. The Mate 20 Pro is water resistant to IP68 standards and has a sleek new design reminiscent of Samsung's S-series phones, with curved glass on the front and back. The back also has an new pattern etched into the glass, which is smooth to the touch but ridged when running your nail over it.

On the back is a new version of Huawei's award-winning triple camera system using a 40-megapixel standard camera, an 8-megapixel telephoto camera with a 3x optical zoom and new for this year is a 20-megapixel ultra-wide angle camera, replacing the monochrome sensor used on the P20 Pro. The Mate 20 Pro runs EMUI 9, which is based on Android 9 Pie. The variant with 6GB of RAM and 128GB of storage is available for 899 Euro starting today.

AmiMoJo shares a report from The Register: The U.S. Food and Drug Administration (FDA) is advising health professionals to keep an eye on some of the equipment they use to monitor pacemakers and other heart implants. The watchdog's alert this week comes after Irish medical device maker Medtronic said it will lock some of its equipment out of its software update service, meaning the hardware can't download and install new code from its servers. That may seem counterintuitive, however, it turns out security vulnerabilities in its technology that it had previously thought could only be exploited locally could actually be exploited via its software update network. Malicious updates could be pushed to Medtronic devices by hackers intercepting and tampering with the equipment's internet connections -- the machines would not verify they were actually downloading legit Medtronic firmware -- and so the biz has cut them off.

The "real version" of Photoshop is coming to the iPad next year, complete with a user interface similar to the desktop application and all the main tools. Ars Technica reports: Photoshop for iPad has a user interface structured similarly to the desktop application. It is immediately familiar to users of the application but tuned for touch screens, with larger targets and adaptations for the tablet as well as gestures to streamline workflows. Both touch and pencil input are supported. The interface is somewhat simpler than the desktop version, and although the same Photoshop code is running under the hood to ensure there's no loss of fidelity, not every feature will be available in the mobile version. The first release will contain the main tools while Adobe plans to add more in the future. Cloud syncing is a key element of Photoshop on iPad. Edits made on the iPad will be synchronized transparently with the desktop -- no conversions or import/export process to go through. Using a feature not available in the iPad version should then be as simple as hitting save and then opening the file on the desktop, picking up where you left off. Adobe is also reportedly building a tablet painting app called Project Gemini, which "simulates real brushes, paints, and materials as well as the interactions between them," reports Ars. "It combines raster graphics, vector drawing, and the Photoshop engine into a single application designed for artwork and illustration."

An anonymous reader quotes a report from Motherboard: Printer maker Epson is under fire this month from activist groups after a software update prevented customers from using cheaper, third party ink cartridges. It's just the latest salvo in a decades-long effort by printer manufacturers to block consumer choice, often by disguising printer downgrades as essential product improvements. For several decades now printer manufacturers have lured consumers into an arguably-terrible deal: shell out a modest sum for a mediocre printer, then pay an arm and a leg for replacement printer cartridges that cost relatively-little to actually produce.

The Electronic Frontier Foundation now says that Epson has been engaged in the same behavior. The group says it recently learned that in late 2016 or early 2017, Epson issued a "poison pill" software update that effectively downgraded user printers to block third party cartridges, but disguised the software update as a meaningful improvement. The EFF has subsequently sent a letter to Texas Attorney General Ken Paxton, arguing that Epson's lack of transparency can easily be seen as "misleading and deceptive" under Texas consumer protection laws. "When restricted to Epson's own cartridges, customers must pay Epson's higher prices, while losing the added convenience of third party alternatives, such as refillable cartridges and continuous ink supply systems," the complaint notes. "This artificial restriction of third party ink options also suppresses a competitive ink market and has reportedly caused some manufacturers of refillable cartridges and continuous ink supply systems to exit the market."
