Dan Robinson reports via The Register: Adding caffeine can enhance the efficiency of fuel cells, reducing the need for platinum in electrodes and significantly reducing the cost of making them, according to researchers in Japan. [...] The study, published in the journal Communications Chemistry, concerns the catalysis process at the cathode of a fuel cell and making this reaction more efficient. Fuel cells work somewhat like batteries. They generate power by converting the chemical energy of a fuel (or electrolyte) and an oxidizing agent into electricity. This is typically hydrogen as a fuel and oxygen as an oxidizer. Unlike batteries with limited lifespans, fuel cells can generate power as long as fuel is supplied. The hydrogen undergoes oxidation at the anode, producing hydrogen ions and electrons. The ions move through the hydrogen electrolyte to the cathode, while the electrons flow through an external circuit, generating electricity. At the cathode, oxygen combines with the hydrogen ions and electrons, resulting in water as a by-product. However, this water impacts the performance of the fuel cell, reacting with the platinum (Pt) to form a layer of platinum hydroxide (PtOH) on the electrode and interfering with the catalysis of the oxygen reduction reaction (ORR), according to the researchers.

To maintain efficient operation, fuel cells require a high Pt loading (greater platinum content), which significantly ups the costs of fuel cells. A quick look online found market prices for platinum of $29.98 per gram, or $932.61 per ounce, at the time of writing. The researchers found that adding caffeine can improve the ORR activity of platinum electrodes 11 fold, making the reaction more efficient. If you are wondering (as we were) how they came to be experimenting with this, the paper explains that modifying electrodes with hydrophobic material is known to be an effective method for enhancing ORR. Caffeine is less toxic than other hydrophobic substances, and it activates the hydrogen evolution and oxidation reactions of Pt nanoparticles and caffeine doped carbons. Got that?

Chiba University's work was led by Professor Nagahiro Hoshi at the Department of Applied Chemistry and Biotechnology. He explained that the researchers found a notable improvement in the electrode's ORR activity with an increase in caffeine concentration in the electrolyte. This forms a thin layer on the electrode's surface, effectively preventing the formation of PtOH, but the effect depends on the orientation of the platinum atoms on the electrode's surface. The paper refers to these as Pt(100), Pt(110) and Pt(111), with the latter two showing increased ORR activity, while there was no noticeable effect with Pt(100). The researchers do not explain if this latter effect might be a problem, but instead claim that their discovery has the potential to improve the designs of fuel cells and lead to more widespread adoption.

The Federal Trade Commission and the Department of Justice have urged the US Copyright Office to broaden exemptions to the Digital Millennium Copyright Act's Section 1201. Specifically, the two agencies are advocating for the extension of the right to repair to include "commercial and industrial equipment," which includes McDonald's ice cream machines that are notorious for breaking down. The Verge reports: Exemptions to DMCA Section 1201 are issued every three years, as per the Register of Copyrights' recommendation. Prior exemptions have been issued for jailbreaking cellphones and repairing certain parts of video game consoles. The FTC and DOJ are asking the Copyright Office to go a step further, extending the right to repair to "commercial and industrial equipment." The comment (PDF) singles out four distinct categories that would benefit from DMCA exemptions: commercial soft serve machines; proprietary diagnostic kits; programmable logic controllers; and enterprise IT. 'In the Agencies' view, renewing and expanding repair-related exemptions would promote competition in markets for replacement parts, repair, and maintenance services, as well as facilitate competition in markets for repairable products," the comment reads.

The inability to do third-party repairs on these products not only limits competition, the agencies say, but also makes repairs more costly and can lead to hundreds or thousands of dollars in lost sales. Certain logic controllers have to be discarded and replaced if they break or if the passwords for them get lost. The average estimated cost of "unplanned manufacturing downtime" was $260,000 per hour, the comment notes, citing research from Public Knowledge and iFixit. As for soft serve machines, breakdowns can lead to $625 in lost sales each day. Business owners can't legally fix them on their own or hire an independent technician to do so, meaning they have to wait around for an authorized technician -- which, the comment says, usually takes around 90 days.

An anonymous reader quotes a report from Wired: We've been ableto design and 3D-print plastic phone cases and toys at home for a decade now. For almost every other consumer product made in a factory, the robots have taken over the heavy lifting. But fashion is still stuck in the 20th century. Take a typical pair of chinos. Cotton threads are woven on a large loom at a mill somewhere in Asia, then shipped to a dye house, then shipped (usually a great distance) to a garment factory somewhere else in Asia. There, the fabric is laid flat and cut into shapes, with the excess fabric being landfilled, incinerated, or (very rarely) recycled. Underpaid and exploited garment workers hand-sew those pieces of fabric into pants, which are then shipped across the ocean to a fulfillment warehouse or a store near you. This global apparel supply chain is inefficient and emissions-heavy -- an estimated 4 percent of global waste and 2 to 4 percent of greenhouse gas emissions are attributed to fashion production. Brands have to make risky predictions many months in advance about which items will sell, leading them to over order on a massive scale.

Now, Walmart is piloting a project with the San Francisco Bay area startup Unspun to test whether it can manufacture the retailer's in-house brand of chinos in the US using a technology called 3D weaving. The experiment is part of a push to nearshore Walmart's supply chain and cut down on emissions and waste associated with textile production. While still very much in the prototype phase -- the two companies are exploring how to use Unspun's technology to supply pants to Walmart's stores -- if successful, this project could upend the way apparel is manufactured on a huge scale. Unspun hopes to eventually deploy 3D weaving micro-factories throughout the United States, so that anyone can order custom and locally made apparel on demand.

According to Bloomberg (paywalled), the Pentagon has reportedly scrapped its plan to allocate $2.5 billion in grants to Intel, causing the firm's stock to slip in extended-hours trading. From a report: The decision now leaves the U.S. Commerce Department, which is responsible for doling out the funds from the U.S. CHIPs and Science Act, to make up the shortfall, the news outlet said. The Commerce Dept. was initially only supposed to cover $1B of the $3.5B that Intel is slated to receive for advanced defense and intelligence-related semiconductors. The deal is slated to position Intel as the dedicated supplier for processors used for military and intelligence applications and could result in a Secure Enclave inside Intel's chip factory, the news outlet said. With the Pentagon reportedly pulling out, it could alter how much Intel and other companies receive from the CHIPs Act, the news outlet said.

After 10 years and billions of dollars spent in development, Apple abruptly canceled its ambitious car project known as "Titan," shifting its focus and resources on the company's artificial intelligence division. In a recent Q&A on Monday, Bloomberg's Mark Gurman (paywalled) shared some new insights about the project and how involved the Apple Silicon team was before it was shut down. According to Gurman, Apple was planning to power the "AI brain" of the car with a custom Apple Silicon chip that would have the equivalent power of four M2 Ultra chips (the most powerful Apple has to date) combined. 9to5Mac reports: A single M2 Ultra chip consists of 134 billion transistors and features a 24-core CPU, a GPU with up to 76 cores, and a dedicated 32-core Neural Engine. M2 Ultra powers the current generation of Mac Studio and Mac Pro. Interestingly, Gurman says that the development of this new chip for the car was "nearly finished" before the project was discontinued. As some of the engineers working on the car project were reassigned to other teams at Apple, the company could reuse the engineering of this new chip for future projects.

Over 15,000 Roku customers were hacked and used to make fraudulent purchases of hardware and streaming subscriptions. According to BleepingComputer, the threat actors were "selling the stolen accounts for as little as $0.50 per account, allowing purchasers to use stored credit cards to make illegal purchases." From the report: On Friday, Roku first disclosed the data breach, warning that 15,363 customer accounts were hacked in a credential stuffing attack. A credential stuffing attack is when threat actors collect credentials exposed in data breaches and then attempt to use them to log in to other sites, in this case, Roku.com. The company says that once an account was breached, it allowed threat actors to change the information on the account, including passwords, email addresses, and shipping addresses. This effectively locked a user out of the account, allowing the threat actors to make purchases using stored credit card information without the legitimate account holder receiving order confirmation emails.

"It appears likely that the same username/password combinations had been used as login information for such third-party services as well as certain individual Roku accounts," reads the data breach notice. "As a result, unauthorized actors were able to obtain login information from third-party sources and then use it to access certain individual Roku accounts. "After gaining access, they then changed the Roku login information for the affected individual Roku accounts, and, in a limited number of cases, attempted to purchase streaming subscriptions." Roku says that it secured the impacted accounts and forced a password reset upon detecting the incident. Additionally, the platform's security team investigated for any charges due to unauthorized purchases performed by the hackers and took steps to cancel the relevant subscriptions and refund the account holders.

A researcher told BleepingComputer last week that the threat actors have been using a Roku config to perform credential stuffing attacks for months, bypassing brute force attack protections and captchas by using specific URLs and rotating through lists of proxy servers. Successfully hacked accounts are then sold on stolen account marketplaces for as little as 50 cents, as seen below where 439 accounts are being sold. The seller of these accounts provides information on how to change information on the account to make fraudulent purchases. Those who purchase the stolen accounts hijack them with their own information and use stored credit cards to purchase cameras, remotes, soundbars, light strips, and streaming boxes. After making their purchases, it is common for them to share screenshots of redacted order confirmation emails on Telegram channels associated with the stolen account marketplaces.

An anonymous reader shared this article from Futurism: More than two years since MIT claimed its scientists achieved a breakthrough in fusion energy, the university is claiming that new research "confirms" that the magnet-based design used in those tests isn't just impressive in a lab setting, but is practical and economically viable, too.

These findings come from a comprehensive report which features six separate [peer-reviewed] studies published in the journal IEEE Transactions on Applied Superconductivity this month, assessing the feasibility of the superconductor magnets used by MIT scientists in their landmark test conducted in September 2021.
"Together, the papers describe the design and fabrication of the magnet and the diagnostic equipment needed to evaluate its performance," MIT announced, "as well as the lessons learned from the process.

"Overall, the team found, the predictions and computer modeling were spot-on, verifying that the magnet's unique design elements could serve as the foundation for a fusion power plant." The successful test of the magnet, says Hitachi America Professor of Engineering Dennis Whyte, who recently stepped down as director of MIT's Plasma Science and Fusion Center, was "the most important thing, in my opinion, in the last 30 years of fusion research." Before the [2021] demonstration, the best-available superconducting magnets were powerful enough to potentially achieve fusion energy — but only at sizes and costs that could never be practical or economically viable. Then, when the tests showed the practicality of such a strong magnet at a greatly reduced size, "overnight, it basically changed the cost per watt of a fusion reactor by a factor of almost 40 in one day," Whyte says.

"Now fusion has a chance," Whyte adds

A recent survey found that academic organizations are failing to preserve digital material -- "including science paid for with taxpayer money," reports Ars Technica, highlighting the need for improved archiving standards and responsibilities in the digital age. From the report: The work was done by Martin Eve, a developer at Crossref. That's the organization that organizes the DOI system, which provides a permanent pointer toward digital documents, including almost every scientific publication. If updates are done properly, a DOI will always resolve to a document, even if that document gets shifted to a new URL. But it also has a way of handling documents disappearing from their expected location, as might happen if a publisher went bankrupt. There are a set of what's called "dark archives" that the public doesn't have access to, but should contain copies of anything that's had a DOI assigned. If anything goes wrong with a DOI, it should trigger the dark archives to open access, and the DOI updated to point to the copy in the dark archive. For that to work, however, copies of everything published have to be in the archives. So Eve decided to check whether that's the case.

Using the Crossref database, Eve got a list of over 7 million DOIs and then checked whether the documents could be found in archives. He included well-known ones, like the Internet Archive at archive.org, as well as some dedicated to academic works, like LOCKSS (Lots of Copies Keeps Stuff Safe) and CLOCKSS (Controlled Lots of Copies Keeps Stuff Safe). The results were... not great. When Eve broke down the results by publisher, less than 1 percent of the 204 publishers had put the majority of their content into multiple archives. (The cutoff was 75 percent of their content in three or more archives.) Fewer than 10 percent had put more than half their content in at least two archives. And a full third seemed to be doing no organized archiving at all. At the individual publication level, under 60 percent were present in at least one archive, and over a quarter didn't appear to be in any of the archives at all. (Another 14 percent were published too recently to have been archived or had incomplete records.)

The good news is that large academic publishers appear to be reasonably good about getting things into archives; most of the unarchived issues stem from smaller publishers. Eve acknowledges that the study has limits, primarily in that there may be additional archives he hasn't checked. There are some prominent dark archives that he didn't have access to, as well as things like Sci-hub, which violates copyright in order to make material from for-profit publishers available to the public. Finally, individual publishers may have their own archiving system in place that could keep publications from disappearing. The risk here is that, ultimately, we may lose access to some academic research.

An anonymous reader quotes a report from Ars Technica: AMD announced this week that it has ceased FreeSync certification for monitors or TVs whose maximum refresh rates are under 144 Hz. Previously, FreeSync monitors and TVs could have refresh rates as low as 60 Hz, allowing for screens with lower price tags and ones not targeted at serious gaming to carry the variable refresh-rate technology. AMD also boosted the refresh-rate requirements for its higher AdaptiveSync tiers, FreeSync Premium and FreeSync Premium Pro, from 120 Hz to 200 Hz.

Here are the new minimum refresh-rate requirements for FreeSync, which haven't changed for laptops. AMD will continue supporting already-certified FreeSync displays even if they don't meet the above requirements. Interestingly, AMD's minimum refresh-rate requirements for TVs goes beyond 120 Hz, which many premium TVs max out at currently, due to the current-generation Xbox and PlayStation supporting max refresh rates of 120 frames per second (FPS). Announcing the changes this week in a blog post, Oguzhan Andic, AMD FreeSync and Radeon product marketing manager, claimed that the changes were necessary, noting that 60 Hz is no longer "considered great for gaming." Andic wrote that the majority of gaming monitors are 144 Hz or higher, compared to in 2015, when FreeSync debuted, and even 120 Hz was "a rarity."

An anonymous reader quotes a report from The Week Magazine: The advancement of new technologies appears to have given rise to a new problem across the United States: a crippling power shortage on the horizon. The advent of these technologies, such as eco-friendly factories and data centers, has renewed concerns that America could run out of electrical power. These worries also come at a time when the United States' aging power grid is in desperate need of repair. Heavily publicized incidents such as the 2021 Texas power outage, which was partially blamed on crypto-farming, exposed how vulnerable the nation's power supply is, especially during emergencies. There have also been warnings from tech moguls such as Elon Musk, who has stated that the United States is primed to run out of electricity and transformers for artificial intelligence in 2025. But the push to extend the life of the nation's power grid, while also maintaining eco-friendly sustainability, begs the question: Is the United States really at risk of going dark?

The emergence of new technologies means demand is soaring for power across the country; in Georgia, "demand for industrial power is surging to record highs, with the projection of electricity use for the next decade now 17 times what it was only recently," Evan Halper said for The Washington Post. Northern Virginia "needs the equivalent of several large nuclear power plants to serve all [its] new data centers," Halper said, while Texas faces a similar problem. This demand is resulting in a "scramble to try to squeeze more juice out of an aging power grid." At the same time, companies are "pushing commercial customers to go to extraordinary lengths to lock down energy sources, such as building their own power plants," Halper said. Much of this relates to the "rapid innovation in artificial intelligence, which is driving the construction of large warehouses of computing infrastructure," Halper said. This infrastructure requires significantly more power than traditional data centers, with the aforementioned crypto farms also sucking up massive amounts of power.

Climate change is also hurting sustainability efforts. A recent report from the North American Electric Reliability Corporation estimated that more than 300 million people in the U.S. and Canada could face power shortages in 2024. It also found that electricity demand is rising faster now than at any time in the past five years. This is partially because the "push for the electrification of heating and transportation systems -- including electric cars -- is also creating new winter peaks in electricity demand," Jeremy Hsu said for New Scientist. One of the main issues with these sustainability efforts is the push to move away from fossil fuels toward renewable power. Natural gas is often seen as a bridge between fossils and renewables, but this has also had unintended consequences for the power grid. The system delivering natural gas "doesn't have to meet the same reliability standards as the electric grid, and in many cases, there's no real way to guarantee that fuel is available for the gas plants in the winter," Thomas Rutigliano of the Natural Resources Defense Council said to New Scientist. As a result, the "North American electricity supply has become practically inseparable from the natural gas supply chain," John Moura of the North American Electric Reliability Corporation said to New Scientist. As such, a "reliable electricity supply that lowers the risk of power outages depends on implementing reliability standards for the natural gas industry moving forward," but this may be easier said than done.

Clare Watson reports via ScienceAlert: By replacing the hazardous chemical electrolytes used in commercial batteries with water, scientists have developed a recyclable 'water battery' -- and solved key issues with the emerging technology, which could be a safer and greener alternative. 'Water batteries' are formally known as aqueous metal-ion batteries. These devices use metals such as magnesium or zinc, which are cheaper to assemble and less toxic than the materials currently used in other kinds of batteries.

Batteries store energy by creating a flow of electrons that move from the positive end of the battery (the cathode) to the negative end (the anode). They expend energy when electrons flow the opposite way. The fluid in the battery is there to shuttle electrons back and forth between both ends. In a water battery, the electrolytic fluid is water with a few added salts, instead of something like sulfuric acid or lithium salt. Crucially, the team behind this latest advancement came up with a way to prevent these water batteries from short-circuiting. This happens when tiny spiky metallic growths called dendrites form on the metal anode inside a battery, busting through battery compartments. [...]

To inhibit this, the researchers coated the zinc anode of the battery with bismuth metal, which oxidizes to form rust. This creates a protective layer that stops dendrites from forming. The feature also helps the prototype water batteries last longer, retaining more than 85 percent of their capacity after 500 cycles, the researchers' experiments showed. According to Royce Kurmelovs at The Guardian, the team has so far developed water-based prototypes of coin-sized batteries used in clocks, as well as cylindrical batteries similar to AA or AAA batteries. The team is working to improve the energy density of their water batteries, to make them comparable to the compact lithium-ion batteries found inside pocket-sized devices. Magnesium is their preferred material, lighter than zinc with a greater potential energy density. [I]f magnesium-ion batteries can be commercialized, the technology could replace bulky lead-acid batteries within a few years. The study has been published in the journal Advanced Materials.

Michelle Lewis reports via Electrek: One of the US's largest nuclear power plants will directly power cloud service provider Amazon Web Services' new data center. Power provider Talen Energy sold its data center campus, Cumulus Data Assets, to Amazon Web Services for $650 million. Amazon will develop an up to 960-megawatt (MW) data center at the Salem Township site in Luzerne County, Pennsylvania. The 1,200-acre campus is directly powered by an adjacent 2.5 gigawatt (GW) nuclear power station also owned by Talen Energy.

The 1,075-acre Susquehanna Steam Electric Station is the sixth-largest nuclear power plant in the US. It's been online since 1983 and produces 63 million kilowatt hours per day. The plant has two General Electric boiling water reactors within a Mark II containment building that are licensed through 2042 and 2044. According to Talen Energy's investor presentation, it will supply fixed-price nuclear power to Amazon's new data center as it's built. Amazon has minimum contractual power commitments that ramp up in 120 MW increments over several years. The cloud service giant has a one-time option to cap commitments at 480 MW and two 10-year extension options tied to nuclear license renewals.

An anonymous reader quotes a report from Ars Technica: Oregon has joined the small but growing list of states that have passed right-to-repair legislation. Oregon's bill stands out for a provision that would prevent companies from requiring that official parts be unlocked with encrypted software checks before they will fully function. Bill SB 1596 passed Oregon's House by a 42 to 13 margin. Gov. Tina Kotek has five days to sign the bill into law. Consumer groups and right-to-repair advocates praised the bill as "the best bill yet," while the bill's chief sponsor, state Sen. Janeen Sollman (D), pointed to potential waste reductions and an improved second-hand market for closing a digital divide.

"Oregon improves on Right to Repair laws in California, Minnesota and New York by making sure that consumers have the choice of buying new parts, used parts, or third-party parts for the gadgets and gizmos," said Gay Gordon-Byrne, executive director of Repair.org, in a statement. Like bills passed in New York, California, and Minnesota, Oregon's bill requires companies to offer the same parts, tools, and documentation to individual and independent repair shops that are already offered to authorized repair technicians. Unlike other states' bills, however, Oregon's bill doesn't demand a set number of years after device manufacture for such repair implements to be produced. That suggests companies could effectively close their repair channels entirely rather than comply with the new requirements. California's bill mandated seven years of availability.

If signed, the law's requirements for parts, tools, and documentation would apply to devices sold after 2015, except for phones, which are covered after July 2021. The prohibition against parts pairing only covers devices sold in 2025 and later. Like other repair bills, a number of device categories are exempted, including video game consoles, HVAC and medical gear, solar systems, vehicles, and, very specifically, "Electric toothbrushes."

HP launched a subscription service this week that rents people a printer, allots them a specific amount of printed pages, and sends them ink for a monthly fee. From a report: HP is framing its service as a way to simplify printing for families and small businesses, but the deal also comes with monitoring and a years-long commitment. Prices range from $6.99 per month for a plan that includes an HP Envy printer (the current model is the 6020e) and 20 printed pages. The priciest plan includes an HP OfficeJet Pro rental and 700 printed pages for $35.99 per month.

HP says it will provide subscribers with ink deliveries when they're running low and 24/7 support via phone or chat (although it's dubious how much you want to rely on HP support). Support doesn't include on or offsite repairs or part replacements. The subscription's terms of service (TOS) note that the service doesn't cover damage or failure caused by, unsurprisingly, "use of non-HP media supplies and other products" or if you use your printer more than what your plan calls for. HP calls this an All-In-Plan; if you subscribe, the tech company will be all in on your printing activities. One of the most perturbing aspects of the subscription plan is that it requires subscribers to keep their printers connected to the Internet. HP seeks two-year subscriber commitments, charging up to $270 plus taxes if canceled early.

Starting today, Ford electric vehicle owners can use one of Tesla's 2,400+ superchargers, but there's a hitch. "They'll need to get an adapter that Ford will provide for free, although the company won't start shipping those until the end of March," notes the Associated Press. Product Reviewer MKBHD also notes that non-Teslas will need to park in a spot that blocks 2 spots where a Tesla would take up one. "If the charge station fills up the remaining spots with Teslas, the app will show 1 charger as available but the parking spot is blocked by the Mach-E," adds MKBHD. From the report: Last May, Ford became the first automaker to reach an agreement with the Austin, Texas-based Tesla to charge on its network, which is the largest and most well-placed in the U.S. Tesla has more than 26,000 plugs and nearly 2,400 Supercharger stations across the U.S. and Canada. Ford said its owners will have access to about 15,000 Tesla fast-charging plugs that are located strategically along travel corridors. Ford owners won't be able to use some older Tesla plugs.

Most other automakers followed Ford in joining Tesla's network and agreeing to switch to Tesla's plug, called the North American Charging Standard, which is smaller and easier to use than the current plugs on most other EVs sold in the two countries. Ford said adding the Tesla plugs will double the size of the network that can be used by Ford EV owners. There are nearly 166,000 Ford EVs in the U.S.

Ford is offering the adapters for free to the owners, who can sign up on the Ford.com website to reserve them between Thursday and June 30. The company will provide one free adapter per vehicle. Tesla's network was turned on Wednesday morning, and software enabling the Ford vehicles to charge at Tesla stations was to be sent out around the same time. Ford will switch to Tesla's charging connector with its second-generation EVs starting next year.

Intel's previously-unannounced Intel 10A (analogous to 1nm) will enter production/development in late 2027, marking the arrival of the company's first 1nm node, and its 14A (1.4nm) node will enter production in 2026. The company is also working to create fully autonomous AI-powered fabs in the future. Tom's Hardware: Intel's Keyvan Esfarjani, the company's EVP and GM and Foundry Manufacturing and Supply, held a very insightful session that covered the company's latest developments and showed how the roadmap unfolds over the coming years. Here, we can see two charts, with the first outlining the company's K-WSPW (thousands of wafer starts per week) capacity for Intel's various process nodes. Notably, capacity typically indicates how many wafers can be started, but not the total output -- output varies based on yields. You'll notice there isn't a label for the Y-axis, which would give us a direct read on Intel's production volumes. However, this does give us a solid idea of the proportionality of Intel's planned node production over the next several years.

Intel did not specify the arrival date of its coming 14A node in its previous announcements, but here, the company indicates it will begin production of the Intel 14A node in 2026. Even more importantly, Intel will begin production/development of its as-yet-unannounced 10A node in late 2027, filling out its roster of nodes produced with EUV technology. Intel's 'A' suffix in its node naming convention represents Angstroms, and 10 Angstroms converts to 1nm, meaning this is the company's first 1nm-class node. Intel hasn't shared any details about the 10A/1nm node but has told us that it classifies a new node as at least having a double-digit power/performance improvement. Intel CEO Pat Gelsinger has told us the cutoff for a new node is around a 14% to 15% improvement, so we can expect that 10A will have at least that level of improvement over the 14A node. (For example, the difference between Intel 7 and Intel 4 was a 15% improvement.)

A federal judge in Texas has granted a temporary order blocking the U.S. government from monitoring the energy usage of cryptocurrency mining operations, stating that the industry had shown it would suffer "irreparable injury" if it was made to comply. The Guardian reports: The US Department of Energy had launched an "eemergency" initiative last month aimed at surveying the energy use of mining operations, which typically use vast amounts of computing power to solve various mathematical puzzles to add new tokens to an online network known as a blockchain, allowing the mining of currency such as bitcoin. The growth of cryptocurrency, and the associated mining of it, has been blamed for a surge in electricity use as data centers have sprung up across the US, even reviving, in some cases, ailing coal plants to help power the mining. [...]

"The massive energy consumption of cryptocurrency mining and its rapid growth in the United States threaten to undermine progress towards achieving climate goals, and threaten grids, communities and ratepayers," said Mandy DeRoche, deputy managing attorney of the clean energy program at Earthjustice. Until now, a lack of publicly available information has only benefited an "industry that has thrived in the shadows," DeRoche added.

The crypto mining industry, however, has claimed it is the victim of a "politically motivated campaign" by Joe Biden's administration and has, for now, succeeded in averting a survey that it contends is unfairly onerous. "This is an attack against legitimate American businesses with the administration feigning an emergency to score political points," said Lee Bratcher, president the Texas Blockchain Council, one of the groups that sued to stop the survey. "The White House has been clear that they desire to 'to limit or eliminate' bitcoin miners from operating in the United States. "Although bitcoin is resilient and cannot be banned, the administration is seeking to make the lives of bitcoin miners, their employees, and their communities too difficult to bear operating in the United States. This is deeply concerning."

Optical discs that can store up to 200 TB of data could be possible with a new technology developed in China. If commercialized, it could revive optical media as an alternative to hard disk or tape for cost-effective long-term storage. The Register: Researchers at the University of Shanghai for Science and Technology (USST) and Shanghai Institute of Optics and Fine Mechanics (SIOM) say they have demonstrated that optical storage is possible up to the petabit level by using hundreds of layers, while also claiming to have broken the optical diffraction barrier limiting how close together recorded features can be.

In an article published in Nature titled "A 3D nanoscale optical disk memory with petabit capacity," the researchers detail how they developed a novel optical storage medium they call dye-doped photoresist (DDPR) with aggregation-induced emission luminogens (AIE-DDPR). When applied as a recording layer, this is claimed to outperform other optical systems and hard drives in terms of areal density -- the amount of storage per unit of area. To be specific, the researchers claim it to be 125 times that of a multi-layer optical disk based on gold nanorods, and 24 times that of the most advanced hard drives (based on data from 2022). The proposed recording and retrieval processes for this medium calls for two laser beams each. For optical writing, a 515 nm femtosecond Gaussian laser beam and a doughnut-shaped 639 nm continuous wave laser beam are focused on the recording area.

Maker Roni Bandini developed a Raspberry Pi project to address his neighbors' loud reggaeton music by creating an AI-driven system that distorts audio on nearby Bluetooth speakers when reggaeton is detected. Tom's Hardware reports: Powering this Bluetooth jamming device is a Raspberry Pi 3 B+. It's connected to a DFRobot OLED display panel, which has a resolution of 128 x 32px. Audio is observed using a USB microphone, while a push button handles when the system will perform a check to listen for any potential reggaeton. According to Bandini, the Pi is running Raspberry Pi OS. The AI system driving the machine learning aspects of the design is Edge Impulse. With this, Bandini was able to train the Pi to listen for music and more specifically identify whether the song playing is classifiable as reggaeton or not. The official project page is available at Hackster.

During a briefing at Mobile World Congress in Barcelona, Meghana Patwardhan, VP of Commercial Mobility at Dell Technology, told The Register that while the immediate future would consist of two worlds -- one with AI hardware and one without -- "every PC is going to be an AI PC in the longer term." From the report: In terms of new hardware, Dell used the Mobile World Congress event in Barcelona to show off new versions of its Surface-baiting Latitude 7350 convertible -- "the world's most serviceable commercial detachable," according to the company -- and its workstation-class Precision 3680 tower.
