More owners of the first-generation Nest Hub are receiving the update to Google's Fuchsia operating system as it expands beyond the Preview program. 9to5Google reports: Back in May, Google formally released Fuchsia, its effort to develop a "not Linux" operating system from scratch, which has been years in the making. The first device to receive the new OS was Google's 2018 smart display, the Nest Hub -- not to be confused with the second generation Nest Hub with sleep tracking released earlier this year -- taking it permanently off of the existing Linux based "Cast OS" without negatively affecting the UI or experience. At the time, the rollout of Fuchsia was limited to a select few devices that were enrolled in the "Preview program" available to all devices via the Google Home app. Over time, the number of Nest Hubs running Fuchsia was expanded, with Google no doubt watching carefully for any issues with the upgrade.

Late last week, Google updated a support page to reflect that the Nest Hub has received a new firmware update for both the Preview program and all other devices. Specifically, the first-gen Nest Hub is now receiving firmware version 1.52.260996. Google confirmed to us that this update does indeed include the upgrade to Fuchsia. All goes well, this means in a matter of days, all first-gen Nest Hub devices in households around the world should be running Fuchsia.

In a statement to CRN, Intel said it was "winding down" RealSense and transferring the talent and computer vision tech to efforts that "better support" its core chip businesses. Engadget reports: Questions surfaced about the fate of RealSense after the team's leader, Sagi Ben Moshe, said he was leaving Intel two weeks ago. RealSense aimed to make computer vision more flexible and accessible. A company or researcher could buy cameras to aid everything from robot navigation through to facial recognition, and there was even a developer-focused phone. It was never a truly mainstream product, though, and ASI VP Kent Tibbils told CRN that there were few customers buying RealSense cameras in any significant quantities. It wasn't really a money-making division, even if the work helped Intel's other teams.

For Intel, there's likely a simpler answer: it wants to cut ballast. CEO Pat Gelsinger wants Intel to reclaim the chipmaking crown, and that means concentrating its resources on design and manufacturing capabilities. No matter how successful RealSense is, it's a potential distraction from Intel's latest strategy.

Since early in the pandemic, soaring demand for consumer electronics led to persistent chip shortages. Some recent signs suggest the situation may finally be starting to change. From a report: An executive at the memory chip maker Micron Technology said last week at an investor conference that demand for consumer PCs is slowing and that some of its customers have more chips lying around. A day later, Morgan Stanley downgraded several chip stocks in a note titled "Winter is Coming." The analysts said PC inventory is rising and that the smartphone market is likely to experience similar deterioration. An old investor maxim says technology companies tend to handily outperform during cyclical upswings while the reverse is true on the downside. Well, the industry is beginning to fall short of estimates.

Global PC shipments grew by 13% in the second quarter, according to research firm IDC. That was below Evercore ISI's expectation of 18% and a big deceleration from the 55% rise in the first quarter. Furthermore, wireless router manufacturer Netgear Inc. gave disappointing guidance last month, adding that sales were worse-than-expected in its consumer networking category. Still, it's probably too soon to declare an end. Outbreaks of the delta variant and the long-term efficacy of vaccines make predictions even harder than usual. Some chip analysts have said reports of weakness are primarily seasonal and that sales will pick up through next year. Shortages also vary by part. So even if you can walk into a store and find plenty of laptops, you'll still struggle to get a new car or a video game console.

In some cases, chip delivery times are longer than 20 weeks, the longest wait in at least four years. But as I wrote last month, the pandemic rush to computers and printers won't repeat itself. Once a worker or student buys a laptop, they don't need another one for several years. Retailers are offering extensive discounts on nearly every PC-related category, with the exception of graphics cards. (It's still a good time to be in the games business.) The waning demand for PCs will likely last for at least several more quarters.

IKEA, the world's biggest furniture brand, is branching out into selling renewable energy to households, starting with home market Sweden in September. Reuters reports: Ingka Group, the owner of most IKEA stores worldwide, said households would be able to buy affordable renewable electricity from solar and wind parks, and track their usage through an app. Ingka's partner Svea Solar, which produces solar panels for IKEA, will buy the electricity on the Nordic power exchange Nord Pool and resell it without surcharge. Households will pay a fixed monthly fee plus a variable rate. IKEA, which also sells solar panels for households in 11 markets, said those buyers would be able to track their own production in the app and sell back surplus electricity. Jonas Carlehed, head of sustainability at IKEA Sweden, told Reuters he hoped to roll out the new renewable energy offer as well as IKEA's solar panel offering to all markets.

An anonymous reader quotes a report from PCMag: Boston Dynamics taught its robots to dance last year, now one of them can complete a parkour course. The robot company, which is owned by Hyundai, has released two new videos today. The first shows off how well the Atlas robot can perform parkour, while the second video takes us behind the scenes and explains how Atlas works. It's actually the first time Atlas has managed to complete the complex obstacle course flawlessly, and Boston wants to celebrate that.

After the dancing video last year, we all expect Boston's robots to do amazing things now, and the parkour video doesn't disappoint. But what it doesn't show is all the hard work, missteps, and problems that need fixing in order to make these demonstrations possible. That's what the second video reveals, and it's the first time I've seen these robots breakdown and leak fluids.

There's a hardware team, a software team, technicians, and operations staff required to make this whole operation work. Each Atlas requires three onboard computers in order to process the sensor data and run the algorithms allowing this 5ft, 190lbs robot to move with 28-degrees of freedom without falling over (very often). And even though we're asking these robots to do the same actions as humans, it's a very different challenge.

UnknowingFool writes: Gigabyte announced it will replace PSU models GP-P850GM and GP-P750GM that fail after HardwareBusters and Gamer's Nexus both showed their PSUs fail catastrophically in small explosions. Gigabyte however downplayed the risk by misstating the failed PSUs only exploded after prolonged extreme conditions and that the problem had been corrected last year. Both HardwareBusters and GamerNexus contest multiple points from Gigabyte. Both stated that their units failed quickly under moderate to light loads. In the case of Gamer's Nexus they obtained some units as late as May 2021.

This issue was first reported in November 2020, when Hardware Busters evaluated a GP-P750GM model and found it exploded during testing. After many Newegg customers reported multiple issues with two Gigabyte models, Gamer's Nexus purchased or obtained units from customers over the course of several months in the spring. Their testing found 5 out of 10 units failed quickly during OPP (Over Power Protection) testing. A normal OPP scenario should have had the PSU shut down to protect itself. Instead, some of the units exploded.

A further complication arose when Newegg customers tried to return failed units. Many of the PSUs were bought in Newegg Shuffle bundles with GPUs, and customers would have to return both the GPU and the PSU. Considering the GPU shortage, most Newegg customers complained about this requirement.

An anonymous reader quotes a report from Interesting Engineering: The Manatee Energy Storage Center -- the world's largest solar-powered battery storage facility -- is now 75% finished with 100 of 132 total containers already installed, reveals a press release from Florida Power and Light Company (FPL). The battery is housed in Manatee County as the name indicates and is expected to be fully operational by the end of the year. When completed, the system will have a 409-MW capacity with the ability to deliver 900 MWh of energy. This is enough electricity to power 329,000 homes for more than two hours.

The battery will serve to replace FPL's coal plants. The battery will store energy in order to bring electricity to homes even when the sun's not shining (at night and on cloudy days) meaning other more polluting power sources will not be required. Although customers are bound to see some financial benefits the main gains will be environmental. According to FPL, each battery module is capable of storing an amount of solar energy equivalent to roughly 2,000 iPhone batteries. The complete battery system will be equivalent to 100 million iPhone batteries and the energy storage containers will be organized across a 40-acre plot of land (the equivalent of 30 football fields). The battery will have a lifespan of 40 years.

The Nokia 9000 Communicator -- "the office in your back pocket" -- was a smartphone even before the word was invented. It has been 25 years since it revolutionized the market. DW: Nokia presented its 9000 Communicator at the CeBIT 1996 computer fair in Hanover, Germany, and launched on August 15 of that year. "The office in your back pocket" added to the IBM Simon from 1994 and the HP OmniGo 700LX from March 1996. The 9000 Communicator was a smartphone even before the word had been invented. For a decade, the device was ââwhat a smartphone was supposed to look like. After the Communicator, Blackberry perfected the idea -- until Apple's iPhone with its multitouch screen in 2007 came along.

Opened like a minilaptop, with a keyboard and a black-and-white display with a diagonal of just 11.5 centimeters (4.5 inches), the retrofuturistic-looking device was made famous by actor Val Kilmer in the remake of the film The Saint. The 9000 Communicator was the first device to offer a combination of keyboard, quality screen, and business and internet software in one package. It had for the first time all of the features of a computer on a phone, putting email, web browsing, fax, word processing and spreadsheets into a single pocketable device.

"Samsung is using artificial intelligence to automate the insanely complex and subtle process of designing cutting-edge computer chips," reports Wired: The South Korean giant is one of the first chipmakers to use AI to create its chips. Samsung is using AI features in new software from Synopsys, a leading chip design software firm used by many companies...

Others, including Google and Nvidia, have talked about designing chips with AI. But Synopsys' tool, called DSO.ai, may prove the most far-reaching because Synopsys works with dozens of companies. The tool has the potential to accelerate semiconductor development and unlock novel chip designs, according to industry watchers. Synopsys has another valuable asset for crafting AI-designed chips: years of cutting-edge semiconductor designs that can be used to train an AI algorithm. A spokesperson for Samsung confirms that the company is using Synopsys AI software to design its Exynos chips, which are used in smartphones, including its own branded handsets, as well as other gadgets...

Chipmakers including Nvidia and IBM are also dabbling in AI-driven chip design. Other makers of chip-design software, including Cadence, a competitor to Synopsys, are also developing AI tools to aid with mapping out the blueprints for a new chip.
But Synopsys's co-CEO tells Wired that Samsung's chip will be "the first of a real commercial processor design with AI."

Lamborghini's exotic Countach sportscar was featured in the opening scene of the 1981 movie Cannonball Run. On the car's 50th anniversary, they've now introduced a 802-horsepower hybrid-electric version. Mashable reports: The reimagined Countach, unveiled in Monterey, California on Friday, is the Italian carmaker's second hybrid. Its drivetrain and performance borrows heavily from the Sián supercar, which was introduced in 2019 as the famous sports car maker's first hybrid. Lamborghini's new Countach (pronounced "coon-tash") has a V12 hybrid engine and 48 volt e-motor, as also seen in the Sián. It can accelerate up to 60 mph in 2.8 seconds and has a 220 mph top speed. Unlike some hybrids, the Countach doesn't have a pure electric mode. Instead, it's always using a blend of the electric motor and gas engine.

The air vents on the back are 3D-printed and the roof is photochromic, meaning it switches from solid to transparent at the push of a button. There are also four exhaust pipes on the backside...

There will only be 112 of Lamborghini's new hybrid Countach ever made...
TechCrunch adds that "Powering the Countach's electric motor is a supercapacitor Lamborghini claims delivers three times more power compared to a lithium-ion battery of the same weight.

"The automaker says it mounted the electric motor directly to the gearbox to preserve the feeling of power transfer you get from a V12 engine."

There's something new in the world of expensive high-performance sportscars (or "hypercars".) Italian carmaker Automobili Pininfarina "has debuted the Battista, the first pure-electric hyper GT, on the streets of California as part of Monterey Car Week," reports Newsweek. (Alternate URL here.) The debut will give U.S. clients the chance to experience the 1,900 horsepower hypercar... [In a video] the Battista, crafted at Automobili Pininfarina's manufacturing facility in Italy, glides smoothly and quickly through California roads at speeds of over 100 miles per hour. The drive shows off the agility of the polished Impulso forged aluminum alloy wheels and exposed bodywork. Pulling off the road, the scissor doors swing open, highlighting the Black Exposed Signature Carbon bodywork.

Supplying the 1,900 hp is a 120-kilowatt-hour battery that powers four electric motors, one in each wheel, that gets about 1696 pound-feet of torque. On a single charge, the car is expected to get a range of over 310 miles.

With an emphasis on the company's "Pure Sound" philosophy and drawing from music theory, the bespoke design of the car is built to have a core frequency of 54 hertz (hz). Wanting to provide an emotional experience for the driver, the organic frequency will rise in multiples of 54 hz as the speed increases.
The company's product platform director of sports cars explains on their web site that "Every driver has an emotional bond with a car and the sound of Battista will nurture this connection, not by replicating a familiar car sound, but with one that radiates the beauty of Battista's design both inside and out. This way, the Battista will not only impress with its aesthetic appeal and performance, but also on a new emotional level enhanced through the sound."

The company's web site also calls it "the most powerful road-legal Italian sports car ever produced."

Ars Technica reports on a paper investigating how much each power plant contributes to global emissions, using data from 2018. "The study finds that many countries have many power plants that emit carbon dioxide at rates well above either the national or global average.

"Shutting down the worst 5 percent of this list would immediately wipe out about 75 percent of the carbon emissions produced by electricity generation." It should surprise nobody that all the worst offenders are coal plants. But the distribution of the highest polluting plants might include a bit of the unexpected.

For example, despite its reputation as the home of coal, China only has a single plant in the top-10 worst (bottom-10?). In contrast, South Korea has three on the list, and India has two. In general, China doesn't have many plants that stand out as exceptionally bad, in part because so many of its plants were built around the same time, during a giant boom in industrialization. As such, there's not much variance from plant to plant when it comes to efficiency. In contrast, countries like Germany, Indonesia, Russia, and the US all see a lot of variance, so they're likely to have some highly inefficient plants that are outliers.

Put a different way, the authors looked at how much of a country's pollution was produced by the worst 5 percent when all of the country's power plants were ranked by carbon emissions. In China, the worst 5 percent accounted for roughly a quarter of the country's total emissions. In the US, the worst 5 percent of plants produced about 75 percent of the power sector's carbon emissions. South Korea had similar numbers, while Australia, Germany, and Japan all saw their worst 5 percent of plants account for roughly 90 percent of the carbon emissions from their power sector. When it comes to carbon emissions, the worst 5 percent of power plants account for 73 percent of the total power sector emissions globally. That 5 percent also produces over 14 times as much carbon pollution as it would if the plants were merely average...

Simply boosting each plant's efficiency to the average for the country would drop power sector emissions by a quarter and up to 35 percent in countries like Australia and Germany. Switching them to natural gas, which produces less carbon dioxide per amount of energy released, would drop global emissions by 30 percent, with many countries (including the US) seeing drops of over 40 percent. Again, because China doesn't see a lot of variance among its plants, these switches would have less of an impact, being in the area of 10 percent drops in emissions. But the big winner is carbon capture and storage. Outfitting the worst of the plants with a capture system that was 85 percent efficient would cut global power sector emissions in half and total global emissions by 20 percent. Countries like Australia and Germany would see their power sector emissions drop by over 75 percent.

Overall, these are massive gains, considering that it's not unreasonable to think that the modifications could be done in less than a decade. And they show the clear value of targeting the easiest wins when it comes to lowering emissions.

"A start-up founded by scientists at the Massachusetts Institute of Technology says it is nearing a technological milestone that could take the world a step closer to fusion energy, which has eluded scientists for decades," reports the New York Times: Researchers at M.I.T.'s Plasma Science and Fusion Center and engineers at the company, Commonwealth Fusion Systems, have begun testing an extremely powerful magnet that is needed to generate immense heat that can then be converted to electricity. It would open the gates toward what they believe could eventually be a fusion reactor... Though a fusion energy breakthrough remains elusive, it is still held out as one of the possible high-technology paths to ending reliance on fossil fuels. And some researchers believe that fusion research could finally take a leap forward this decade. More than two dozen private ventures in the United States, Europe, China and Australia and government-funded consortia are now investing heavily in efforts to build commercial fusion reactors. Total investment by people such as Bill Gates and Jeff Bezos is edging toward $2 billion. The federal government is also spending about $600 million each year on fusion research, and there is a proposed amendment to add $1 billion to the Biden administration's infrastructure bill, said Andrew Holland, chief executive of the Fusion Industry Association...

Commonwealth's new magnet, which will be one of the world's most powerful, will be a crucial component in a compact nuclear fusion reactor known as a Tokamak, a design that uses magnetic forces to compress plasma until it is hotter than the sun... Commonwealth Fusion executives claim that the magnet is a significant technology breakthrough that will make Tokamak designs commercially viable for the first time. They say they are not yet ready to test their reactor prototype, but the researchers are finishing the magnet and hope it will be workable by 2025...

Commonwealth, which has raised more than $250 million so far and employs 150 people, received a significant boost last year when physicists at M.I.T.'s Plasma Science and Fusion Center and the company published seven peer-reviewed papers in the Journal of Plasma Physics explaining that the reactor will work as planned. What remains to be proved is that the Commonwealth prototype reactor can produce more energy than it consumes, an ability that physicists define as Q greater than 1. The company is hoping that its prototype, when complete, will produce 10 times the energy it consumes.
Commonwealth's chief executive (also a plasma physicist) explains to the Times how fusion energy is different than other sources: because it really doesn't require any resources. "You add up all the costs, the cost of normal stuff like concrete and steel, and it will make as much power as a gas plant, but without having to pay for the gas."

Google's Pixel 6 phone will be powered by a Tensor processor which PCMag UK believes is "clearly designed to accelerate machine learning and AI." But does it have bigger implications? Tensor is a signpost, not a destination. Google has never sold huge numbers of Pixel phones and isn't signaling a change in strategy there. Rather, it's saying that it would like Android as a whole to shift toward more on-device processing for AI and ML. That could give a big boost to Google's two core businesses, advertising and data. It could also create problems for the future of 5G...

The more your phone can handle its own ML and AI, the less it needs the cloud. For example, a Tensor-enabled phone could potentially analyze your photos and share data locally with on-device advertising APIs, letting Google proclaim that its cloud services never access your raw data. That would help bridge the gap between the privacy you want and the targeted ads Google needs to survive. But a lot of consumer 5G app ideas assume your phone will offload processing or rendering onto the network.

Phones that are mostly self-sufficient aren't going to need high-bandwidth, low-latency networks or "mobile edge computing." Sure, the rise of more Tensor-like ML-focused chips would take pressure off the carriers' still-shaky 5G builds, but it'll also keep raising the question of why consumers need 5G in the first place. That could reduce carriers' willingness to keep investing in their consumer 5G networks.
Although the first sence of the article's last paragraph adds, "Maybe I'm overstating the issue here..."

The Register's Richard Speed commemorates the 40th anniversary of the introduction of the IBM Model 5150: IBM was famously late to the game when the Model 5150 (or IBM PC) put in an appearance. The likes of Commodore and Apple pretty much dominated the microcomputer world as the 1970s came to a close and the 1980s began. Big Blue, on the other hand, was better known for its sober, business-orientated products and its eyewatering price tags. However, as its customers began eying Apple products, IBM lumbered toward the market, creating a working group that could dispense with the traditional epic lead-times of Big Blue and take a more agile approach. A choice made was to use off-the-shelf hardware and software and adopt an open architecture. A significant choice, as things turned out.

Intel's 8088 was selected over the competition (including IBM's own RISC processor) and famously, Microsoft was tapped to provide PC DOS as well as BASIC that was included in the ROM. So this marks the 40th anniversary of PC DOS, aka MS-DOS, too. You can find Microsoft's old MS-DOS source code here. The basic price for the 5150 was $1,565, with a fully loaded system rising to more than $3,000. Users could enjoy high resolution monochrome text via the MDA card or some low resolution graphics (and vaguely nauseating colors) through a CGA card (which could be installed simultaneously.) RAM landed in 16 or 64kB flavors and could be upgraded to 256kB while the Intel 8088 CPU chugged along at 4.77 MHz.

Storage came courtesy of up to two 5.25" floppy disks, and the ability to attach a cassette recorder -- an option swiftly stripped from later models. There was no hard disk, and adding one presented a problem for users with deep enough pockets: the motherboard and software didn't support it and the power supply was a bit weedy. IBM would resolve this as the PC evolved. Importantly, the motherboard also included slots for expansion, which eventually became known as the Industry Standard Architecture (ISA) bus as the IBM PC clone sector exploded. IBM's approach resulted in an immense market for expansion cards and third party software. While the Model 5150 "sold like hotcakes," Speed notes that it was eventually discontinued in 1987.

Today, Samsung launched the Galaxy Watch 4 and Galaxy Watch 4 Classic -- two new wearables that are "the fruits of Samsung's smartwatch collaboration with Google," writes Becca Farsace via The Verge. From the report: The Watch 4 Classic starts at $349 for the Bluetooth model, rising to $399 for the LTE model, while the Watch 4 is a little less expensive with a starting price of $249 (or $299 with LTE). Both are available to preorder today, and ship August 27th. The big difference between the two models is that the Watch 4 Classic has one of those physical rotating bezels that we've liked so much on Samsung's previous smartwatches, while if you opt for the standard Watch 4, there's a touch-sensitive bezel accessible by swiping at the edges of the screen. The Watch 4 Classic is also made of a more premium stainless steel rather than the aluminum you'll find on the Watch 4. On the right of both watches are a pair of control buttons.

External differences aside, internally both watches share a lot of the same specs. They're both powered by the same 5nm Exynos W920 processor Samsung detailed yesterday, paired with 1.5GB of RAM and 16GB of storage. Battery capacity varies between sizes, but Samsung reckons you'll average around 40 hours of battery life regardless of model. There's LTE on select models, but if you were hoping for 5G, you'll be disappointed -- Samsung says it doesn't think it's worth it because the amount of data smartwatches process is too small.

But the biggest departure from Samsung's previous smartwatches is that the Watch 4 and Watch 4 Classic aren't running its own Tizen operating system. Instead, their software is the result of a collaboration between Samsung and Google, which was announced in May. Samsung is branding the watches' operating system as "Wear OS Powered by Samsung" although Google has called it Wear OS 3. But either way, the hope is that it combines the best of Tizen with the best of Wear OS. On Samsung's watches specifically, the interface you're looking at is One UI Watch, which is effectively Samsung's skin sitting on top of Wear OS. Think of it as Samsung's One UI software on phones, which works with Google's Android. It gives the Watch 4's interface a similar look and feel to Samsung's previous Tizen-powered watches. Google has promised its collaboration with Samsung will lead to a host of high-level benefits for Wear OS, like improved battery life, faster loading apps, and smoother animations.

labloke11 shares a report from Science News: Windbreaks may sound like a counterintuitive idea for boosting the performance of a wind turbine. But physicists report that low walls that block wind could actually help wind farms produce more power. Scientists already knew that the output of a single wind turbine could be improved with a windbreak. While windbreaks slow wind speed close to the ground, above the height of the windbreak, wind speeds actually increase as air rushes over the top. But for large wind farms, there's a drawback. A windbreak's wake slows the flow of air as it travels farther through the rows of turbines. That could suggest that windbreaks would be a wash for wind farms with many turbines.

But by striking a balance between these competing effects, windbreaks placed in front of each turbine can increase power output, new computer simulations suggest. It comes down to the windbreaks' dimensions. Squat, wide barriers are the way to go, according to a simulated wind farm with six rows of turbines. To optimize performance, windbreaks should be a tenth the height of the turbine and at least five times the width of the blades, physicists report July 30 in Physical Review Fluids. Such an arrangement could increase the total power by about 10 percent, the researchers found. That's the equivalent of adding an additional turbine, on average, for every 10 in a wind farm. In the simulations, the wind always came from the same direction, suggesting the technique might be useful in locations where wind tends to blow one way, such as coastal regions. Future studies could investigate how this technique might apply in places where wind direction varies.

An anonymous reader quotes a report from Ars Technica: Google is cooking up the first major Wear OS release since 2018, and Samsung is abandoning Tizen for smartwatches and going all-in on Wear OS with the Galaxy Watch 4. Last night, Samsung took the wraps off the main SoC for the Galaxy Watch 4, and compared to what Wear OS usually gets, Samsung is shipping a beast of an SoC. The "Samsung Exynos W920" will be a multi-generational leap in performance for Wear OS. Samsung says this is a 5 nm chip with two ARM Cortex A55 cores and an ARM Mali-G68 GPU. For the always-on display mode, there's an additional Cortex M55 CPU, which can keep the watch face ticking along while using minimal power. There's also an integrated LTE modem for on-the-go connectivity.

Compared to Samsung's previous smartwatch chip, the Tizen-only Exynos 9110 (10 nm, 2x Cortex A53), the company is promising "around 20 percent" better CPU performance and "ten times better graphics performance." Remember that the Exynos 9110 is from 2018, so those comparative numbers are inflated, but at 5 nm, this is a more modern chip than Wear OS has ever seen. Wear OS has suffered for years at the hands of Qualcomm, which has been starving the ecosystem of quality SoCs for wearables. Most people's last experience with Wear OS is the Snapdragon Wear 2100 or 3100 SoCs, both of which were ancient Cortex A7 CPUs built on a 28 nm process. Qualcomm introduced a slightly more modern chip, the Wear 4100 in 2020 (a Cortex A53-based, 12 nm chip), but almost no manufacturers actually shipped that chip a year later, and we're still getting Wear 3100 launches today. Qualcomm's answer to Samsung's chip will be the Wear 5100, which isn't due until 2022. We should know more about Wear OS 3.0 tomorrow when Samsung holds its Aug. 11 "Unpacked" event. Not only are they expected to reveal the Galaxy Watch 4 and the big Wear OS revamp, but they're planning to launch at least two new foldable smartphones -- the Galaxy Z Fold 3 and Galaxy Z Flip 3.

While some bitcoin mining operations are now looking to nuclear power, the Associated Press reports, Bill Spence (and his company Stronghold Digital Mining) is creating crypto-mining hubs out of waste coal power plants. (Text-only version here): The plant he had bought was in trouble. It was competing with cheap natural gas on the power grid and losing — endangering the 35 jobs at Scrubgrass Generating Station along with the effort to clean up millions of tons of leaching coal waste left behind by mining companies over the course of decades. The plant couldn't just rely on the grid for revenue anymore, because the grid simply didn't need its power all that often. Mr. Spence started to look for other customers...

Already, some power generators — finding they can make more money supplying electricity to Bitcoin-mining operations than selling it to the grid — are shifting focus. Energy Harbor, which owns the Beaver Valley Nuclear Plant in Beaver County, announced earlier this month that it will supply nuclear power to a Bitcoin-mining data center in Ohio. Talen Energy, owner of the Susquehanna Steam Electric Station in Luzerne County, is doing the same. The company said last month that it will develop a data center to mine digital currency that could use up to 300 megawatts, or 12% of the nuclear plant's capacity. Bitcoin miners, in turn, are hyper cognizant of power prices and availability. Some are taking mobile units into the oil fields, hooking up their machines to run on natural gas, a byproduct of oil product that would otherwise be flared...

Today, Scrubgrass, an 85-megawatt blue box with a black smokestack in the hills of Scrubgrass Township, looks much like it did when it first opened in 1993 — except for the trailers filled with Bitcoin miners in the back... [T]here are about 3,000 cryptocurrency miners packed into retrofitted shipping containers behind the power plant, most of them owned by Stronghold and some that belong to other mining companies that buy power from the plant. Another 5,000 machines are scheduled to arrive next month. According to documents filed with the SEC, Stronghold is planning to operate 57,000 miners by the end of next year. In 2020, when the power plant seldom ran, Stronghold made more money from its Bitcoin operations than by selling Scrubgrass's energy to the grid. During the first three months of this year, the trend reversed. It received almost $2 million from power sales and more than $1 million from its crypto datacenter...

Stronghold is buying another waste coal plant, Panther Creek Energy Facility in Carbon County, with plans to replicate its cryptomining data center there, and is eyeing a third.
The Associated Press notes that the waste-coal plants are powered by those thousands of acres of abandoned (and pollutant-emitting) coal piles left behind by earlier coal-powered plants, finally remediating them into reclaimable land. But with waste coal plants, there's always a trade-off.

"In 2019, the last year with available federal data, Scrubgrass emitted the equivalent of 371,000 tons of CO2 — the greenhouse gas footprint of 80,000 cars driving for a year."

An anonymous reader quotes a report from Live Science: Scientists have created key parts of synthetic brain cells that can hold cellular "memories" for milliseconds. The achievement could one day lead to computers that work like the human brain. In the new study, published in the journal Science on Aug. 6, researchers at the Centre national de la recherche scientifique in Paris, France created a computer model of artificial neurons that could produce the same sort of electrical signals neurons use to transfer information in the brain; by sending ions through thin channels of water to mimic real ion channels, the researchers could produce these electrical spikes. And now, they have even created a physical model incorporating these channels as part of unpublished, ongoing research. At a finer level, the researchers created a system that mimics the process of generating action potentials -- spikes in electrical activity generated by neurons that are the basis of brain activity. To generate an action potential, a neuron starts to let in more positive ions, which are attracted to the negative ions inside of the cell. The electrical potential, or voltage across the cell membrane, causes doorways on the cell called voltage-gated ion channels to open, raising the charge even more before the cell reaches a peak and returns to normal a few milliseconds later. The signal is then transmitted to other cells, enabling information to travel in the brain.

To mimic voltage-gated ion channels, the researchers modeled a thin layer of water between sheets of graphene, which are extremely thin sheets of carbon. The water layers in the simulations were one, two, or three molecules in depth, which the researchers characterized as a quasi-two-dimension slit. [T]he researchers wanted to use this two-dimensional environment because particles tend to react much more strongly in two dimensions than in three, and they exhibit different properties in two dimensions, which the researchers thought might be useful for their experiment. Testing out the model in a computer simulation, the researchers found that when they applied an electric field to the channel, the ions in the water formed worm-like structures. As the team applied a greater electric field in the simulation, these structures would break up slowly enough to leave behind a "memory," or a hint of the elongated configuration.

When the researchers ran a simulation linking two channels and other components to mimic the behavior of a neuron, they found the model could generate spikes in electrical activity like action potentials, and that it "remembered" consistent properties in two different states -- one where ions conducted more electricity and one where they conducted less. In this simulation, the "memory" of the previous state of the ions lasted a few milliseconds, around the same time as it takes real neurons to produce an action potential and return to a resting state. This is quite a long time for ions, which usually operate on timescales of nanoseconds or less. In a real neuron, an action potential equates to a cellular memory in the neuron; our brains use the opening and closing of ion channels to create this kind of memory. The new model is a version of an electronic component called a memristor, or a memory resistor, which has the unique property of retaining information from its history. But existing memristors don't use liquid, as the brain does.
