An anonymous reader quotes a report from BleepingComputing: The Ragnar Locker ransomware gang have published download links for more than 700GB of archived data stolen from Taiwanese memory and storage chip maker ADATA. A set of 13 archives, allegedly containing sensitive ADATA files, have been publicly available at a cloud-based storage service, at least for some time. [...] Two of the leaked archives are quite large, weighing over 100GB, but several of them that could have been easily downloaded are less than 1.1GB large. Per the file metadata published by the threat actor, the largest archive is close to 300GB and its name gives no clue about what it might contain. Another large one is 117GB in size and its name is just as nondescript as in the case of the first one (Archive#2). Judging by the names of the archives, Ragnar Locker likely stole from ADATA documents containing financial information, non-disclosure agreements, among other type of details.

The ransomware attack on ADATA happened on May 23rd, 2021, forcing them to take systems offline, the company told BleepingComputer. As the Ragnar Locker leak clearly shows, ADATA did not pay the ransom and restored the affected systems on its own. The ransomware actor claims stealing 1.5TB of sensitive files before deploying the encryption routine, saying that they took their time in the process because of the poor network defenses. The recently leaked batch of archives is the second one that Ragnar Locker ransomware publishes for ADATA. The previous one was posted earlier this month and includes four small 7-zip archives (less than 250MB together) that can still be downloaded.

Bloomberg Businessweek reports on "renewed interest in cables that can power consumers in one country with electricity generated hundreds, even thousands, of miles away in another" and possibly even transcontinental, submarine electricity superhighways: Coal, gas and even nuclear plants can be built close to the markets they serve, but the utility-scale solar and wind farms many believe essential to meet climate targets often can't. They need to be put wherever the wind and sun are strongest, which can be hundreds or thousands of miles from urban centers. Long cables can also connect peak afternoon solar power in one time zone to peak evening demand in another, reducing the price volatility caused by mismatches in supply and demand as well as the need for fossil-fueled back up capacity when the sun or wind fade. As countries phase out carbon to meet climate goals, they'll have to spend at least $14 trillion to strengthen grids by 2050, according to Bloomberg New Energy Finance. That's only a little shy of projected spending on new renewable generation capacity and it's increasingly clear that high- and ultra-high-voltage direct current lines will play a part in the transition.

The question is how international will they be...?
The article points out that in theory, Mongolia's Gobi desert "has potential to deliver 2.6 terawatts of wind and solar power — more than double the U.S.'s entire installed power generation capacity — to a group of Asian powerhouse economies that together produce well over a third of global carbon emissions..." The same goes for the U.S., where with the right infrastructure, New York could tap into sun- and wind-rich resources from the South and Midwest. An even more ambitious vision would access power from as far afield as Canada or Chile's Atacama Desert, which has the world's highest known levels of solar power potential per square meter. Jeremy Rifkin, a U.S. economist who has become the go-to figure for countries looking to remake their infrastructure for the digital and renewable future, sees potential for a single, 1.1 billion-person electricity market in the Americas that would be almost as big as China's. Rifkin has advised Germany and the EU, as well as China...

Persuading countries to rely on each other to keep the lights on is tough, but the universal, yet intermittent nature of solar and wind energy also makes it inevitable, according to Rifkin. "This isn't the geopolitics of fossil fuels," owned by some and bought by others, he says. "It is biosphere politics, based on geography. Wind and sun force sharing...."

If these supergrids don't get built, it will be because their time has both come and gone. Not only are they expensive, politically difficult, and unpopular — they have to cross a lot of backyards — their focus on mega-power installations seems outdated to some. Distributed microgeneration as close to home as your rooftop, battery storage, and transportable hydrogen all offer competing solutions to the delivery problems supergrids aim to solve.

In the longest biological experiment on the International Space Station yet, freeze-dried mouse sperm remained viable after nearly six years in space. Exposure to space radiation didn't seem to harm the sperm's DNA or the cells' ability to produce healthy "space pups," researchers report in Science Advances. Science News reports: That may be good news for future spacefarers. Scientists have worried that chronic exposure to space radiation might not only put astronauts at risk for cancer and other diseases, but also create mutations in their DNA that could be passed down to future generations. The new results hint that deep-space travelers could safely bear children. Studying how space radiation affects reproduction is tricky. Instruments on Earth can't perfectly mimic space radiation, and the ISS lacks freezers for long-term cell storage. So biologist Teruhiko Wakayama of the University of Yamanashi in Kofu, Japan and colleagues freeze-dried sperm, allowing it to be stored at room temperature. The team then sent sperm from 12 mice to the space station, while keeping other sperm from the same mice on the ground.

After returning the sperm cells to Earth, rehydrating them and injecting them into fresh mouse eggs, the team transferred those embryos to female mice. About 240 healthy space pups were born from sperm kept on the ISS for nearly three years; about 170 others were born from sperm kept on the space station for nearly six years. Genetic analyses revealed no differences between these space pups and mice born from sperm stored on the ground. Space pups that mated as adults had healthy children and grandchildren.

Apple has begun testing passkeys, a new authentication technology it says are as easy to use as passwords but vastly more secure. Part of iCloud Keychains, a test version of the technology will come with iPhones, iPads and Macs later this year. From a report: To set up an account on a website or app using a passkey, you first choose a username for the new account, then use FaceID or Touch ID to confirm that it's really you who's using the device. You don't ever pick a password. Your device handles generation and storage of the passkey, which iCloud Keychain synchronizes across all your Apple devices.

To use the passkey for authentication later, you'll be prompted to confirm your username and verify yourself with FaceID or Touch ID. Developers must update their login procedures to support passkeys, but it's an adaptation of the existing WebAuthn technology. "Because it's just a single tap to sign in, it's simultaneously easier, faster and more secure than almost all common forms of authentication today," Garrett Davidson, an Apple authentication experience engineer, said Wednesday at the company's annual WWDC developer conference.

Graphene can be used for ultra-high density hard disk drives (HDD), with up to a tenfold jump compared to current technologies, researchers at the Cambridge Graphene Center have shown. Phys.Org reports: The study, published in Nature Communications, was carried out in collaboration with teams at the University of Exeter, India, Switzerland, Singapore, and the US. [...] HDDs contain two major components: platters and a head. Data are written on the platters using a magnetic head, which moves rapidly above them as they spin. The space between head and platter is continually decreasing to enable higher densities. Currently, carbon-based overcoats (COCs) -- layers used to protect platters from mechanical damages and corrosion -- occupy a significant part of this spacing. The data density of HDDs has quadrupled since 1990, and the COC thickness has reduced from 12.5nm to around 3nm, which corresponds to one terabyte per square inch. Now, graphene has enabled researchers to multiply this by ten.

The Cambridge researchers have replaced commercial COCs with one to four layers of graphene, and tested friction, wear, corrosion, thermal stability, and lubricant compatibility. Beyond its unbeatable thinness, graphene fulfills all the ideal properties of an HDD overcoat in terms of corrosion protection, low friction, wear resistance, hardness, lubricant compatibility, and surface smoothness. Graphene enables two-fold reduction in friction and provides better corrosion and wear than state-of-the-art solutions. In fact, one single graphene layer reduces corrosion by 2.5 times. Cambridge scientists transferred graphene onto hard disks made of iron-platinum as the magnetic recording layer, and tested Heat-Assisted Magnetic Recording (HAMR) -- a new technology that enables an increase in storage density by heating the recording layer to high temperatures. Current COCs do not perform at these high temperatures, but graphene does. Thus, graphene, coupled with HAMR, can outperform current HDDs, providing an unprecedented data density, higher than 10 terabytes per square inch.

Engineers at MIT have recently announced that they have successfully developed a programmable fiber. Interesting Engineering reports: Featured in Nature Communications, this new research could result in the development of wearable tech that could sense, store, analyze, and infer the activity(s) of its wearers in real-time. The senior author of the study, Yeol Fink, believes that digital fibers like those developed in this study could help expand the possibilities for fabrics to "uncover the context of hidden patterns in the human body that could be used for physical performance monitoring, medical inference, and early disease detection." Applications for the technology could even expand into other areas of our lives like, for example, storing wedding music within the bride's gown.

The fibers were created by chaining hundreds of microscale silicon digital chips into a preform to make a new "smart" polymer fiber. By using precision control, the authors of the study were able to create fibers with the continuous electrical connection between each chip of tens of meters. These fibers are thin and flexible and can even be passed through the eye of a needle. This would mean they could be seamlessly (pun intended) woven into existing fabrics, and can even withstand being washed at least ten times without degrading. This would mean this wearable tech could be retrofitted to existing clothing and you wouldn't even know it's there. Such innovation is interesting, but it could open up doors for applications only ever dreamed of.

The fiber also has a pretty decent storage capacity too -- all things considered. During the research, it was found to be possible to write, store, and recall 767-kilobit full-color short movie files and a 0.48-megabyte music file. The files can be stored for two months without power. The fibers also integrate a neural network with thousands of connections. This was used to monitor and analyze the surface body temperature of a test subject after being woven into the armpit of the shirt. By training the neural network with 270-minutes of data the team got it to predict the minute-by-minute activity of the shirt's wearer with 96% accuracy. The fibers are also controlled using a small external device that could have microcontrollers added to it in the future.

Apple is rolling out some updates to iCloud under the name iCloud+. Existing paid iCloud users are going to get those iCloud+ features for the same monthly subscription price. From a report: In Safari, Apple is going to launch a new privacy feature called Private Relay. It sounds a bit like the new DNS feature that Apple has been developing with Cloudflare. Originally named Oblivious DNS-over-HTTPS, Private Relay could be a better name for something quite simple -- a combination of DNS-over-HTTPS with proxy servers. When Private Relay is turned on, nobody can track your browsing history -- not your internet service provider, anyone standing in the middle of your request between your device and the server you're requesting information from.

The second iCloud+ feature is 'Hide my email.' It lets you generate random email addresses when you sign up to a newsletter or when you create an account on a website. If you've used 'Sign in with Apple,' you know that Apple offers you the option to use fake iCloud email addresses. This works similarly, but for any app. Finally, Apple is overhauling HomeKit Secure Video. With the name iCloud+, Apple is separating free iCloud users from paid iCloud users. Basically, you used to pay for more storage. Now, you pay for more storage and more features. Subscriptions start at $0.99 per month for 50GB (and iCloud+ features).

It's been argued that technology (especially automation) will continue weakening the position of workers. But today the senior economics correspondent for The New York Times argues a "profound shift" happening in America is instead something else.

"For the first time in a generation, workers are gaining the upper hand..." Up and down the wage scale, companies are becoming more willing to pay a little more, to train workers, to take chances on people without traditional qualifications, and to show greater flexibility in where and how people work. The erosion of employer power began during the low-unemployment years leading up to the pandemic and, given demographic trends, could persist for years. March had a record number of open positions, according to federal data that goes back to 2000, and workers were voluntarily leaving their jobs at a rate that matches its historical high. Burning Glass Technologies, a firm that analyzes millions of job listings a day, found that the share of postings that say "no experience necessary" is up two-thirds over 2019 levels, while the share of those promising a starting bonus has doubled.

People are demanding more money to take a new job. The "reservation wage," as economists call the minimum compensation workers would require, was 19 percent higher for those without a college degree in March than in November 2019, a jump of nearly $10,000 a year, according to a survey by the Federal Reserve Bank of New York... [T]he demographic picture is not becoming any more favorable for employers eager to fill positions. Population growth for Americans between ages 20 and 64 turned negative last year for the first time in the nation's history. The Congressional Budget Office projects that the potential labor force will grow a mere 0.3 to 0.4 percent annually for the remainder of the 2020s; the size of the work force rose an average of 0.8 percent a year from 2000 to 2020.
The article describes managers now "being forced to learn how to operate amid labor scarcity... At the high end of the labor market, that can mean workers are more emboldened to leave a job if employers are insufficiently flexible on issues like working from home..."

But it also notes a ride-sharing driver who switched to an IBM apprenticeship for becoming a cloud storage engineer, and former Florida nightclub bouncer Alex Lorick, who became an IBM mainframe technician, "part of a deliberate effort by IBM to rethink how it hires and what counts as a qualification for a given job." [IBM] executives concluded that the qualifications for many jobs were unnecessarily demanding. Postings might require applicants to have a bachelor's degree, for example, in jobs that a six-month training course would adequately prepare a person for.

"By creating your own dumb barriers, you're actually making your job in the search for talent harder," said Obed Louissaint, IBM's senior vice president for transformation and culture. In working with managers across the company on training initiatives like the one under which Mr. Lorick was hired, "it's about making managers more accountable for mentoring, developing and building talent versus buying talent."

"I think something fundamental is changing, and it's been happening for a while, but now it's accelerating," Mr. Louissaint said.

Billionaire Bill Gates' advanced nuclear reactor company TerraPower LLC and PacifiCorp have selected Wyoming to launch the first Natrium reactor project on the site of a retiring coal plant, the state's governor said on Wednesday. Reuters reports: TerraPower, founded by Gates about 15 years ago, and power company PacifiCorp, owned by Warren Buffet's Berkshire Hathaway, said the exact site of the Natrium reactor demonstration plant is expected to be announced by the end of the year. Small advanced reactors, which run on different fuels than traditional reactors, are regarded by some as a critical carbon-free technology than can supplement intermittent power sources like wind and solar as states strive to cut emissions that cause climate change.

The project features a 345 megawatt sodium-cooled fast reactor with molten salt-based energy storage that could boost the system's power output to 500 MW during peak power demand. TerraPower said last year that the plants would cost about $1 billion. Late last year the U.S. Department of Energy awarded TerraPower $80 million in initial funding to demonstrate Natrium technology, and the department has committed additional funding in coming years subject to congressional appropriations.

In a Q&A with TechRadar, storage hardware giant Seagate revealed it is keeping a close eye on the crypto space, with a view to potentially launching a new line of purpose-built drives. From the report: Asked whether companies might develop storage products specifically for cryptocurrency use cases, Jason M. Feist, who heads up Seagate's emerging products arm, said it was a "possibility." Feist said he could offer no concrete information at this stage, but did suggest the company is "exploring this opportunity and imagines others may be as well."

"For the first time, artificial intelligence was a key component and power multiplier in fighting the enemy," says a senior officer in the intelligence corps of the Israeli military, describing the technology's use in 11 days of fighting in the Gaza Strip.

They're quoted in a Jerusalem Post article on "the world's first AI war": Soldiers in Unit 8200, an Intelligence Corps elite unit, pioneered algorithms and code that led to several new programs called "Alchemist," "Gospel" and "Depth of Wisdom," which were developed and used during the fighting. Collecting data using signal intelligence, visual intelligence, human intelligence , geographical intelligence, and more, the Israel Defense Forces (IDF) has mountains of raw data that must be combed through to find the key pieces necessary to carry out a strike. "Gospel" used AI to generate recommendations for troops in the research division of Military Intelligence, which used them to produce quality targets and then passed them on to the IAF to strike...

While the IDF had gathered thousands of targets in the densely populated coastal enclave over the past two years, hundreds were gathered in real time, including missile launchers that were aimed at Tel Aviv and Jerusalem. The military believes using AI helped shorten the length of the fighting, having been effective and quick in gathering targets using super-cognition. The IDF carried out hundreds of strikes against Hamas and PIJ, including rocket launchers, rocket manufacturing, production and storage sites, military intelligence offices, drones, commanders' residences and Hamas's naval commando unit. Israel has destroyed most of the naval commando unit's infrastructure and weaponry, including several autonomous GPS-guided submarines that can carry 30 kg. of explosives.

IDF Unit 9900's satellites have gathered geographical intelligence over the years. They were able to automatically detect changes in terrain in real time so that during the operation, the military was able to detect launching positions and hit them after firing. For example, Unit 9900 troops using satellite imagery were able to detect 14 rocket launchers that were located next to a school... One strike, against senior Hamas operative Bassem Issa, was carried out with no civilian casualties despite being in a tunnel under a high-rise building surrounded by six schools and a medical clinic... Hamas's underground "Metro" tunnel network was also heavily damaged over the course of several nights of airstrikes. Military sources said they were able to map the network, consisting of hundreds of kilometers under residential areas, to a degree where they knew almost everything about them.

The mapping of Hamas's underground network was done by a massive intelligence-gathering process that was helped by the technological developments and use of Big Data to fuse all the intelligence.

Slashdot reader sciencehabit shares Science magazine's look at efforts to transform zinc batteries "from small, throwaway cells often used in hearing aids into rechargeable behemoths that could be attached to the power grid, storing solar or wind power for nighttime or when the wind is calm." With startups proliferating and lab studies coming thick and fast, "Zinc batteries are a very hot field," says Chunsheng Wang, a battery expert at the University of Maryland, College Park. Lithium-ion batteries — giant versions of those found in electric vehicles — are the current front-runners for storing renewable energy, but their components can be expensive. Zinc batteries are easier on the wallet and the planet — and lab experiments are now pointing to ways around their primary drawback: They can't be recharged over and over for decades.

For power storage, "Lithium-ion is the 800-pound gorilla," says Michael Burz, CEO of EnZinc, a zinc battery startup. But lithium, a relatively rare metal that's only mined in a handful of countries, is too scarce and expensive to back up the world's utility grids. (It's also in demand from automakers for electric vehicles.) Lithium-ion batteries also typically use a flammable liquid electrolyte. That means megawatt-scale batteries must have pricey cooling and fire-suppression technology. "We need an alternative to lithium," says Debra Rolison, who heads advanced electrochemical materials research at the Naval Research Laboratory. Enter zinc, a silvery, nontoxic, cheap, abundant metal. Nonrechargeable zinc batteries have been on the market for decades. More recently, some zinc rechargeables have also been commercialized, but they tend to have limited energy storage capacity. Another technology — zinc flow cell batteries — is also making strides. But it requires more complex valves, pumps, and tanks to operate. So, researchers are now working to improve another variety, zinc-air cells...

Advances are injecting new hope that rechargeable zinc-air batteries will one day be able to take on lithium. Because of the low cost of their materials, grid-scale zinc-air batteries could cost $100 per kilowatt-hour, less than half the cost of today's cheapest lithium-ion versions. "There is a lot of promise here," Burz says. But researchers still need to scale up their production from small button cells and cellphone-size pouches to shipping container-size systems, all while maintaining their performance, a process that will likely take years.

The ability to boot from an external drive on an Apple Silicon Mac may not be an option for much longer, with the creation and use of the drives apparently being phased out by Apple, according to developers of backup tools. Apple Insider reports: Mike Bombich, the founder of Bombich Software behind Carbon Copy Cloner, wrote in a May 19 blog post that the company will continue to make bootable backups for both Intel and Apple Silicon Macs, and will "continue to support that functionality as long as macOS supports it." However, with changes in the way a Mac functions with the introduction of Apple Silicon, the ability to use external booting could be limited, in part due to Apple's design decisions.

The first problem is with macOS Big Sur, as Apple made it so macOS resides on a "cryptographically sealed Signed System Volume," which could only be copied by Apple Software Restore. While CCC has experience with ASR, the tool was deemed to be imperfect, with it failing "with no explanation" and operating in a "very one-dimensional" way. The second snag was Apple Fabric, a storage system that uses per-file encryption keys. However, ASR didn't work for months until the release of macOS 11.3 restored it, but even then kernel panics ensued when cloning back to the original internal storage.

In December, Bombich spoke to Apple about ASR's reliability and was informed that Apple was working to resolve the problem. During the call, Apple's engineers also said that copying macOS system files was "not something that would be supportable in the future." "Many of us in the Mac community could see that this was the direction Apple was moving, and now we finally have confirmation," writes Bombich. "Especially since the introduction of APFS, Apple has been moving towards a lockdown of macOS system files, sacrificing some convenience for increased security." [...] While CCC won't drop the ability to copy the System folder, the tool is "going to continue to offer it with a best effort' approach." Meanwhile, for non-bootable data restoration, CCC's backups do still work with the macOS Migration Assistant, available when booting up a new Mac for the first time.

Almost half a decade after the first reports were published, mobile app developers are still exposing their users' personal information through abhorrently simple misconfigurations. From a report: In a report published last week, security firm Check Point said it found 23 Android applications that exposed the personal data of more than 100 million users through a variety of misconfigurations of third-party cloud services. This included developers who forgot to password-protect their backend databases and developers who left access tokens/keys inside their mobile application's source code for services such as cloud storage or push notifications. The Check Point team said it was able to use the information they found through a routine examination of 23 random applications and access the backend databases of 13 apps. In the exposed databases, researchers said they found information such as email addresses, passwords, private chats, location coordinates, user identifiers, screen recordings, social media credentials, and personal images.

An anonymous reader quotes a report from Ars Technica: Seagate has been working on dual-actuator hard drives -- drives with two independently controlled sets of read/write heads -- for several years. Its first production dual-actuator drive, the Mach.2, is now "available to select customers," meaning that enterprises can buy it directly from Seagate, but end-users are out of luck for now. Seagate lists the sustained, sequential transfer rate of the Mach.2 as up to 524MBps -- easily double that of a fast "normal" rust disk and edging into SATA SSD territory. The performance gains extend into random I/O territory as well, with 304 IOPS read / 384 IOPS write and only 4.16 ms average latency. (Normal hard drives tend to be 100/150 IOPS and about the same average latency.)

The added performance requires additional power; Mach.2 drives are rated for 7.2 W idle, while Seagate's standard Ironwolf line is rated at 5 W idle. It gets more difficult to compare loaded power consumption because Seagate specs the Mach.2 differently than the Ironwolf. The Mach.2's power consumption is explicitly rated for several random I/O scenarios, while the Ironwolf line is rated for an unhelpful "average operating power," which isn't defined in the data sheet. Still, if we assume -- probably not unreasonably -- a similar expansion of power consumption while under load, the Mach.2 represents an excellent choice for power efficiency since it offers roughly 200% of the performance of competing traditional drives at roughly 144% of the power budget. Particularly power-conscious users can also use Seagate's PowerBalance mode -- although that feature decreases sequential performance by 50% and random performance by 10%.

An anonymous reader quotes a report from Phys.Org: All future fossil fuel projects must be scrapped if the world is to reach net-zero carbon emissions by 2050 and to stand any chance of limiting warming to 1.5C, the International Energy Agency said Tuesday. In a special report designed to inform negotiators at the crucial COP26 climate summit in Glasgow in November, the IEA predicted a "sharp decline in fossil fuel demand" in the next three decades as well as a 2040 deadline for the global energy sector to achieve carbon neutrality. The Paris-based think tank called for a rapid and vast ramping up of renewable energy investment and capacity, which bring gains in development, wealth and human health.

IEA Executive Director Fatih Birol said the roadmap outlined in the report showed that the path to global net-zero by 2050 was "narrow but still achievable." "The scale and speed of the efforts demanded by this critical and formidable goal -- our best chance of tackling climate change and limiting global warming to 1.5C -- make this perhaps the greatest challenge humankind has ever faced," he said. "Under the IEA's net-zero pathway, oil usage is projected to decline 75 percent and gas 55 percent by mid-century," the report notes. "It also said that all inefficient coal power plants needed to close by 2030 in order to achieve net-zero by 2050."

The IEA went on to say that around half of reductions by 2050 would be provided by "technologies that are currently only in demonstration or prototype phase," which include direct air capture and storage of CO2 from the atmosphere.

Implantable miniaturized medical devices that wirelessly transmit data "are transforming healthcare and improving the quality of life for millions of people," writes Columbia University, noting the devices are "widely used to monitor and map biological signals, to support and enhance physiological functions, and to treat diseases."

Long-time Slashdot reader sandbagger shares the university's newest announcement: These devices could be used to monitor physiological conditions, such as temperature, blood pressure, glucose, and respiration for both diagnostic and therapeutic procedures. To date, conventional implanted electronics have been highly volume-inefficient — they generally require multiple chips, packaging, wires, and external transducers, and batteries are often needed for energy storage... Researchers at Columbia Engineering report that they have built what they say is the world's smallest single-chip system, consuming a total volume of less than 0.1 mm cubed. The system is as small as a dust mite and visible only under a microscope...

"We wanted to see how far we could push the limits on how small a functioning chip we could make," said the study's leader Ken Shepard, Lau Family professor of electrical engineering and professor of biomedical engineering. "This is a new idea of 'chip as system' — this is a chip that alone, with nothing else, is a complete functioning electronic system. This should be revolutionary for developing wireless, miniaturized implantable medical devices that can sense different things, be used in clinical applications, and eventually approved for human use...."

The chip, which is the entire implantable/injectable mote with no additional packaging, was fabricated at the Taiwan Semiconductor Manufacturing Company with additional process modifications performed in the Columbia Nano Initiative cleanroom and the City University of New York Advanced Science Research Center (ASRC) Nanofabrication Facility. Shepard commented, "This is a nice example of 'more than Moore' technology—we introduced new materials onto standard complementary metal-oxide-semiconductor to provide new function. In this case, we added piezoelectric materials directly onto the integrated circuit to transducer acoustic energy to electrical energy...." The team's goal is to develop chips that can be injected into the body with a hypodermic needle and then communicate back out of the body using ultrasound, providing information about something they measure locally.

The current devices measure body temperature, but there are many more possibilities the team is working on.

Framework is one of an increasing number of companies working to address planned obsolescence by creating products that are incredibly customizable and easy to repair. Today, the company's Framework Laptop is up for preorder, starting at $999 and shipping at the end of July. TechCrunch reports: There are three basic configurations -- Base, Performance and Professional, ranging from $999 to $1,999, upgrading from an Intel Core i5, 8GB of Ram and 256GB of storage to a Core i7 and 32GB/1TB. Windows also gets upgraded from Home to Pro at the top level. At $749, the company offers a barebones shell, where users can plug in their own internals.

Other upgrades include: "On top of that, the Framework Laptop is deeply customizable in unique ways. Our Expansion Card system lets you choose the ports you want and which side you want them on, selecting from four at a time of USB-C, USB-A, HDMI, DisplayPort, MicroSD, ultra-fast 250GB and 1TB storage, and more. Magnetic-attach bezels are color-customizable to match your style, and the keyboard language can be swapped too."

A carbon-free future "will require many millions of batteries, both to drive electric vehicles and to store wind and solar power on the grid," reports IEEE Spectrum. Unfortunately, today's battery chemistries "mostly rely on lithium — a metal that could soon face a global supply crunch." Recently, Rystad Energy projected a "serious lithium supply deficit" in 2027 as mining capacity lags behind the EV boom. The mismatch could effectively delay the production of around 3.3 million battery-powered passenger cars that year, according to the research firm. Without new mining projects, delays could swell to the equivalent of 20 million cars in 2030. Battery-powered buses, trucks, ships, and grid storage systems will also feel the squeeze... [T]he solution isn't as simple as mining more hard rock — called spodumene — or tapping more underground brine deposits to extract lithium. That's because most of the better, easier-to-exploit reserves are already spoken for in Australia (for hard rock) and in Chile and Argentina (for brine). To drastically scale capacity, producers will also need to exploit the world's "marginal" resources, which are costlier and more energy-intensive to develop than conventional counterparts...

Concerns about supply constraints are driving innovation in the lithium industry. A handful of projects in North America and Europe are piloting and testing "direct lithium extraction," an umbrella term for technologies that, generally speaking, use electricity and chemical processes to isolate and extract concentrated lithium... In southwestern Germany, Vulcan Energy is extracting lithium from geothermal springs that bubble thousands of meters below the Rhine river. The startup began operating its first pilot plant in mid-April. Vulcan said it could be extracting 15,000 metric tons of lithium hydroxide — a compound used in battery cathodes — per year. In southern California, Controlled Thermal Resources is developing a geothermal power plant and lithium extraction facility at the Salton Sea. The company said a pilot facility will start producing 20,000 metric tons per year of lithium hydroxide, also by 2024.

Another way to boost lithium supplies is to recover the metal from spent batteries, of which there is already ample supply. Today, less than 5 percent of all spent lithium-ion batteries are recycled, in large part because the packs are difficult and expensive to dismantle. Many batteries now end up in landfills, leaching chemicals into the environment and wasting usable materials. But Sophie Lu, the head of metals and mining for BloombergNEF, said the industry is likely to ramp up recycling after 2028, when the supply deficit kicks in. Developers are already starting to build new facilities, including a $175 million plant in Rochester, N.Y. When completed, it will be North America's largest recycling plant for lithium-ion batteries.
The Economic Times also argues that electric cars and renewable energy "may not be as green as they appear. Production of raw materials like lithium, cobalt and nickel that are essential to these technologies are often ruinous to land, water, wildlife and people.

"That environmental toll has often been overlooked in part because there is a race underway among the United States, China, Europe and other major powers. Echoing past contests and wars over gold and oil, governments are fighting for supremacy over minerals that could help countries achieve economic and technological dominance for decades to come."

A Windows Defender bug creates thousands of small files that waste gigabytes of storage space on Windows 10 hard drives. BleepingComputer reports: The bug started with Windows Defender antivirus engine 1.1.18100.5 and will cause the C:\ProgramData\Microsoft\Windows Defender\Scans\History\Store folder to be filled up with thousands of files with names that appear to be MD5 hashes. From a system seen by BleepingComputer, the created files range in size from 600 bytes to a little over 1KB. While the system we looked at only had approximately 1MB of files, other Windows 10 users report that their systems have been filled up with hundreds of thousands of files, which in one case, used up 30GB of storage space. On smaller SSD system drives (C:), this can be a considerable amount of storage space to waste on unnecessary files. According to Deskmodder, who first reported on this issue, the bug has now been fixed in the latest Windows Defender engine, version 1.1.18100.6.
