"If I get to do another Avatar film, it'll be because the business model still works," James Cameron tells CNN in a video interview — adding "That I can't guarantee, as I sit here today. That'll play out over the next month, really." He says theatre is a "sacred space," and while it will never go away, "I think that it could fall below a threshhold where the kinds of movies that I like to make and that I like to see... won't be sustainable, they won't be economically viable. And that can happen. We're very close to that right now."

The Wrap notes he filmed his new movie at the same time as its predecessor, The Way of Water." "We did all the performance capture in an 18-month period for both films. Then we did a lot of the virtual camera work to figure out exactly how we were going to do the live-action," Cameron explained. "Then we did all live-action together for both films. Then we split it and said, All right, now we just got to finish [movie] two....." While Cameron has been iffy about whether the previously announced fourth and fifth films will actually happen, he has already shot some of the fourth movie. "We're in a fluid scenario. Theatrical's contracting, streaming is expanding. People's habit patterns are changing. The teen demo consumes media differently than what we grew up with. And how much is it changing? Does theatrical contract to a point where it just stops right and doesn't get any smaller because we still value that, or does it continue to wither away?" Cameron said.
It's a theme he continued in his interview with The Hollywood Reporter" "This can be the last one. There's only one [unanswered question] in the story. We may find that the release of Avatar 3 proves how diminished the cinematic experience is these days, or we may find it proves the case that it's as strong as it ever was — but only for certain types of films. It's a coin toss right now. We won't know until the middle of January."

I ask something that might sound odd: What do you want to happen? But Cameron gets the implication. "That's an interesting question," he says. "I feel I'm at a bit of a crossroads. Do I want it to be a wild success — which almost compels me to continue and make two more Avatar movies? Or do I want it to fail just enough that I can justify doing somethingelse...?"

"What won't happen is, I won't go down the rabbit hole of exclusively making only Avatar for multiple years. I'm going to figure out another way that involves more collaboration. I'm not saying I'm going to step away as a director, but I'm going to pull back from being as hands-on with every tiny aspect of the process..." Cameron won't reveal his next project — and he might even be unsure himself — but will give intriguing hints. In addition to co-directing Billie Eilish's upcoming 3D concert documentary, Hit Me Hard and Soft, Cameron has another globe-trotting documentary adventure in the works, the details of which are under wraps. His next narrative film probably won't be Ghosts of Hiroshima, which has generated considerable press after Cameron acquired the rights to Charles Pellegrino's book chronicling the true story of Tsutomu Yamaguchi, who in 1945 survived the nuclear blasts at both Hiroshima and Nagasaki. Cameron promised Yamaguchi on his deathbed in 2010 that he'd makethefilm. "The postapocalypse is not going to be the fun that it is in science fiction," he says. "It's not going to have mutants and monsters and all sorts of cool stuff. It's hell...."

Cameron first portrayed the apocalypse in his 1984 debut, The Terminator, a franchise he's quietly working on revisiting. "Once the dust clears on Avatar in a couple of months, I'm going to really plunge into that," he says. "There are a lot of narrative problems to solve. The biggest is how do I stay enough ahead of what's really happening to make it science fiction?" Asked whether he's cracked the premise, Cameron replies, "I'm working on it," but his sly smile suggests that he has.... There needs to be a broader interpretation of Terminator and the idea of a time war and super intelligence. I want to do new stuff that people aren't imagining."
Maybe Cameron's best response was what he told USA Today: "Let's do another interview in a year and then I'll tell you what my plans are," Cameron, 71, says with a grin. For now, he's still catching his breath.

After popular arcade games like Mortal Kombat and Spy Hunter, Midway Games jumped into the home console market, and in 2003 launched their baseball game franchise "MLB Slugfest" for Xbox, PS2, and GameCube. But at times it was almost a parody of baseball, including announcers filling the long hours of airtime with bizarre, rambling conversations. ("I read today that kitchen utensils are gonna hurt more people tonight than lifting heavy objects during the day...")

Now former Midway Games producer Mark Flitman has revealed the even weirder conversations rejected by Major League Baseball. ("Ah, baseball on a sunny afternoon. Is there anything better? We've been talking about breaking pop bottles with rocks. I guess that is...") The nonprofit Video Game History Foundation published the text in their digital archive — and shared 79 seconds of sound clips that were actually recorded but never used in the final game. ("Enjoying some smoked whale meat up here in the booth today...")

Their BlueSky post with the audio drew over 5,500 likes and 2,400 reposts, with one commenter wondering if the bizarre (and unapproved) conversations were "part of the tactic where you include overtly inappropriate content to make the stuff you actually want to keep seem more appropriate." But the Foundation's library director thinks the voice actors were just going wild. "We talked with Mark on our podcast and it sounds like they just did a lot of improv and got carried away." He added later that the game's producer "would give them prompts and they'd run with it. The voice actors (Kevin Matthews and Tim Kitzrow) have backgrounds in sports radio and comedy, so they came up with wild nonsense like this."

The gaming site Aftermath notes the Foundation also has an archive page for all the other sound files on the CD. Maybe it's the ultimate tribute to the craziness that was MLB Slugfest. Years ago some fans of the game shared their memories on Reddit...

• "The first time my friend tried to bean me and my hitter caught the ball was so hype, we were freaking out. Every game quickly evolved into trying to get our hitters to charge the mound."

• "I just remembered you could also kick the shit out of the fielder near your base if he got too close. Man that game was awesome."

• "You could do jump kicks into the catcher like Richie from The Benchwarmers."

• "Every time someone got on base we would run the ball over to them and beat their asses for 30 seconds. Good times."

Six years after the launch of the franchise, Midway Games declared bankruptcy.

An anonymous reader shares a report: When Coinbase's quarterly earnings call wrapped up Thursday, its chief executive, Brian Armstrong, didn't finish with profit guidance or statements of confidence. He closed it out with a list: "Bitcoin, Ethereum, blockchain, staking and Web3." Those weren't random buzzwords. They were part of an $84,000 betting market [non-paywalled source].

Across prediction market platforms Kalshi and Polymarket, users had wagered on which words would be spoken during the call -- part of a niche category known as mention markets, where the outcome isn't tied to earnings, price moves or sports games, but to what people say in some public forum. With the final analyst question complete, several terms listed in contracts were still unsaid. Armstrong ticked them off one by one.

"I was a little distracted because I was tracking the prediction market about what Coinbase will say on their next earnings call," he said in his parting remarks. "I just want to add here the words Bitcoin, Ethereum, blockchain, staking, and Web3 -- to make sure we get those in before the end of the call." The exchange's CEO had just moved a market -- even if only a small one.

Mention markets are one of the more curious byproducts of the broader prediction market boom, but also one of the more controversial. Platforms like Kalshi, which is regulated by the Commodity Futures Trading Commission, and Polymarket, which is in the process of returning to the US market, let users wager on the outcomes of real-world events. That can mean elections, policy decisions, or sports -- but also, increasingly, corporate rituals and even common jargon.

An anonymous reader shares a report: The iPhone 17 Pro and 17 Pro Max appear to provide little resistance to scratches and scuffs around the sharp edges of the camera bump. Tech blogger Zack Nelson demonstrates this weakness in a durability test on his JerryRigEverything YouTube channel, explaining that the anodized aluminium layer on the iPhone 17 Pro and 17 Pro Max "does not stick to corners very well" -- creating a weak point in the coating. This is a known issue with the electrochemical anodizing process, so it was a design decision Apple knowingly made.

"For some reason, Apple didn't add a chamfer, fillet, or radius around the camera plateau, and I think it was intentional, so it looks cooler," Nelson says in the video. "But that decision to look cool out of the box is going to plague everyone who owns this phone down the road." The video shows that everyday objects, like a coin or house key carried in the same pocket as the iPhone 17 Pro, can chip away at the anodized coating around the sharp corners of the camera bump. However, that same mildly aggressive scratching on the flat surface of the camera plateau only produced dust that could be easily wiped away.

A new study analyzing distorted sound waves from the early universe suggests we may live in a massive cosmic void "with roughly 20% lower than the average density of matter," writes Indranil Banik in an article for The Conversation. "Not every physicist is convinced that this is the case. But our recent paper analyzing distorted sounds from the early universe, published in the Monthly Notices of the Royal Astronomical Society, strongly backs up the idea." Slashdot reader alternative_right shares an excerpt from the report: My colleagues and I previously argued that the Hubble tension might be due to our location within a large void. That's because the sparse amount of matter in the void would be gravitationally attracted to the more dense matter outside it, continuously flowing out of the void. In previous research, we showed that this flow would make it look like the local universe is expanding about 10% faster than expected. That would solve the Hubble tension. But we wanted more evidence. And we know a local void would slightly distort the relation between the BAO angular scale and the redshift due to the faster moving matter in the void and its gravitational effect on light from outside.

So in our new paper, Vasileios Kalaitzidis and I set out to test the predictions of the void model using BAO measurements collected over the last 20 years. We compared our results to models without a void under the same background expansion history. In the void model, the BAO ruler should look larger on the sky at any given redshift. And this excess should become even larger at low redshift (close distance), in line with the Hubble tension. The observations confirm this prediction. Our results suggest that a universe with a local void is about one hundred million times more likely than a cosmos without one, when using BAO measurements and assuming the universe expanded according to the standard model of cosmology informed by the CMB.

Our research shows that the ACDM model without any local void is in "3.8 sigma tension" with the BAO observations. This means the likelihood of a universe without a void fitting these data is equivalent to a fair coin landing heads 13 times in a row. By contrast, the chance of the BAO data looking the way they do in void models is equivalent to a fair coin landing heads just twice in a row. In short, these models fit the data quite well. In the future, it will be crucial to obtain more accurate BAO measurements at low redshift, where the BAO standard ruler looks larger on the sky -- even more so if we are in a void. The average expansion rate so far follows directly from the age of the universe, which we can estimate from the ages of old stars in the Milky Way. A local void would not affect the age of the universe, but some proposals do affect it. These and other probes will shed more light on the Hubble crisis in cosmology.

Bitcoin mining has crossed a critical economic threshold, with costs now exceeding market value for most operators. According to data cited by CoinShares, large public mining companies spend over $82,000 to produce a single Bitcoin -- nearly double last quarter's figure -- while smaller operations face even steeper costs of approximately $137,000 per coin.

With Bitcoin currently trading around $94,703, the math no longer works for most miners. The economics become particularly challenging in high-electricity-cost regions like Germany, where mining a single coin requires approximately $200,000. Industry analysts suggest larger mining operations are adapting by optimizing energy consumption and positioning their computational infrastructure for alternative uses. These companies can potentially lease their mining setups for other computational tasks during unprofitable mining periods, then resume mining when market conditions improve.

For individual miners, however, the era of profitable home operations appears effectively over, as industrial-scale facilities with strategic positioning and optimized technology have fundamentally altered the mining landscape.

Despite a January announcement that America would explore the idea of a national digital asset stockpile, the exact cryptocurrecies weren't specified. Today on social media the president posted that it would include bitcoin, ether, XRP, Solana's SOL token and Cardano's ADA, reports CNBC — prompting a Sunday rally in cryptocurrencies trading. XRP surged 33% after the announcement while the token tied to Solana jumped 22%. Cardano's coin soared more than 60%. Bitcoin rose 10% to $94,425.29, after dipping to a three-month low under $80,000 on Friday. Ether, which has suffered some of the biggest losses in crypto year-to-date, gained 12%... This is the first time Trump has specified his support for a crypto "reserve" versus a "stockpile." While the former assumes actively buying crypto in regular installments, a stockpile would simply not sell any of the crypto currently held by the U.S. government.
"The total cryptocurrency market has risen about 10%," reports Reuters, "or more than $300 billion, in the hours since Trump's announcement, according to CoinGecko, a cryptocurrency data and analysis company."

"A U.S. Crypto Reserve will elevate this critical industry..." the president posted, promising to "make sure the U.S. is the Crypto Capital of the World," reports The Hill: His announcement comes just after the White House announced it would be welcoming cryptocurrency industry professionals on March 7 in a first-of-its-kind summit... It's unclear what exactly Trump's crypto reserve would look like, and while he previously dismissed crypto as a scam, he's embraced the industry throughout his most recent campaign.

"Nuclear you can trust," reads the web page promoting "The Egg, an at home nuclear reactor."

Yes, Enron.com is now announcing "a micro-nuclear reactor made to power your home." (A quick reminder from CNN in December. "A company that makes T-shirts bought the Enron trademark and appears to be trying to sell some merch on behalf of the guy behind the satirical conspiracy theory "Birds Aren't Real....")

Does that explain how we got a product reveal for "the world's first micro-nuclear reactor for residential suburban use"? (Made possible "by the Enron mining division, which has been sourcing the proprietary Enronium ore...") Enron's new 28-year-old CEO Connor Gaydos insists they're "making the world a better place, one egg at a time."

The Houston Chronicle delves into the details: Supposedly a micro-nuclear reactor capable of powering a home for up to 10 years, the Enron Egg would be a significant leap forward for both energy technology and humanity's understanding of nuclear physics — if, of course, such a thing were actually feasible. "With our current understanding of physics, this will never be possible," said Derek Haas, an associate professor and nuclear and radiation engineering researcher at the University of Texas at Austin. "We can make a nuclear reactor go critical at about the size of the egg that I saw on the pictures. But we can't capture that energy and turn it into useful electric heat, and shield the radiation that comes off of the reactor." [Haas adds later that nuclear reactors require federal licenses to operate, which take two to nine years to procure and "typically require several hundred pages of documentation to be allowed to build it, and then another thousand pages of safety documents to be allowed to turn it on."]

The outlandish claims Enron has made in the weeks since its brand revival have left many to speculate that the move is part of some large-scale joke similar to Birds Aren't Real — a gag conspiracy movement that Connor Gaydos, Enron's 28-year-old CEO, published a book on alongside co-author and movement founder Peter McIndoe. In an exclusive interview with the Houston Chronicle, Gaydos asked that people look past the limitations — be they in the form of regulations or physics — and embrace the impossible....

Several since-deleted blurbs — both on the company's website and on social media — have alluded to Enron potentially expanding into the world of cryptocurrency. Gaydos said he hasn't ruled it out, but the company currently does not have any plans in the works to debut an Enron-themed coin. "I think in a lot of ways, everything feels like a crypto scam now, but thankfully, we are a completely real company," Gaydos said.
When announcing the Egg, Gaydos stressed Enron was now revolutionizing not just the power industry, but also two others — the freedom industry, and the independence industry. And Gaydos reminded his audience that their home micro-nuclear was "safe for the whole family."

"Preorder now," adds the Egg's web page at Enron.com. "Sign up for our email newsletter and be the first to know when we launch..."

Have you been to Enron.com lately?

"It's the comeback story no one asked for," reports CNN, "the resurrection of a brand so toxic it remains synonymous with corporate fraud more than two decades after it collapsed in bankruptcy.

"That's right, folks: Enron is back. But only kind of." TL;DR: A company that makes T-shirts bought the Enron trademark and appears to be trying to sell some merch on behalf of the guy behind the satirical conspiracy theory "Birds Aren't Real...."

On Monday, the 23rd anniversary of Enron's filing for bankruptcy, rumors began to spread that the former Texas energy giant had come back from the dead. A sleek new website, enron.com, appeared to show that the company had done some serious soul-searching and, inexplicably, reincorporated under its original brand. As a modern energy company, it would be dedicated to "solving the global energy crisis," its press statement reads. The site is packed with the kind of stock art and benign corporate platitudes that lend it credibility. There's a link to job openings, employee testimonials and even a minute-long video titled "I am Enron," a movie-trailer-style mashup of cityscape time lapses, rockets launching into space, a ballerina twirling on a beach — a mess of imagery and baritone voiceover so trite it's almost believable.

But the site and its associated social media accounts are, like Enron's balance sheets, mostly fiction. Unlike the Enron scandal, however, this one appears to be little more than performance art designed to sell branded hoodies. Publicly available documents show that an Akansas-based LLC called The College Company bought the Enron trademark for $275 in 2020... You can tab over to the site's "Company Store" page to browse a selection of Enron-branded hoodies ($118 before tax and shipping), puffer vests ($89), tees ($40) baseball hats ($40), beanies ($30) and water bottles emblazoned with the slogan "you've got great energy."
Somewhere on the site CNN spotted a list of "key pillars" which included a commitment to "permissionless innovation," which CNN took to be "a nod that prompted some speculation online that the new 'Enron' would launch some kind of digital token." That phrase has apparently been changed now to "continuous innovation." An Enron-branded X account posted and later deleted a message teasing at a crypto offering, saying "we do not have any token or coin (yet). Stay tuned, we are excited to show you more soon."
But sharp-eyed X.com users also found the key context to add: that the Terms of Use at Enron.com declare the site's information "is First Amendment-protected parody, represents performance art, and is for entertainment purposes only."

Still, the site includes this testimonial from someone it says is a current employee. "Like many of my peers in the Enron family, I was skeptical at first.

"Now, not only do I have complete confidence in the integrity of the company, I also genuinely believe that we are leading the way for a new chapter of American business."

An anonymous reader shared this report from Business Insider: It's a political tale as old as time: put up a campaign poster in your yard, and thieves come to snatch it. But according to The Wall Street Journal, those fed up with front lawn looting are embracing a modern solution. Apple's geo-tracking AirTag devices are helping owners find their signs — and sometimes, even the people who stole them.

The practice has already led to charges. In one example cited by the outlet, Florida politician John Dittmore decided to hide the coin-sized gadget on one of his posters after waking up to a number of thefts in May... [Two teenagers were charged with criminal mischief and the theft of nine signs.]

In other cited cases, stolen signs don't end up with teens, but in the homes of electoral opponents. After Chris Torre became the victim of poster snatching, AirTags led him to the residence of Renee Rountree, the Journal said. Both were running for a seat on the Isle of Wight County Board of Supervisors in Virginia. Her son-in-law was charged with a misdemeanor for stealing the property, while Rountree faced a misdemeanor for receiving stolen goods. In a December trial, she noted plans to return the signs. Rountree has since been ordered to 250 hours of community service.

"I would like to think that this will have a huge deterrent effect," the trial's judge said in the court's transcript, quoted by WSJ.

Rocio Fabbro reports via Quartz: TDK, the largest maker of smartphone batteries in the world, said Monday that it has successfully developed a material that could be used in a new battery with "significantly higher energy density" than its existing cells. Energy density refers to how much energy a battery can store relative to its size or weight. The material will be used in TDK's CeraCharge solid-state battery, which it says has an energy density of 1,000 watt-hours per liter -- approximately 100 times more than its conventional solid-state battery. These batteries use an oxide-based solid electrolyte, in contrast with the liquid electrolyte used in lithium-ion batteries that are widely found in electronic devices, making them "extremely safe." Solid-state batteries are smaller, charge faster, last longer, and have a lower risk of damage from temperature changes. "Smaller size and higher capacitance contribute to smaller device size and longer operating time," the Tokyo-based company said.

The battery is designed to replace coin cell primary batteries, such as those found in wearable devices like wireless headphones, smartwatches, and hearing aids. The new batteries would be rechargeable, in compliance with new European Union battery regulations that are aimed at reducing the environmental impact of batteries. TDK said it's working toward mass production of solid-state batteries, and beefing up the batteries' capacity using multi-layer lamination technology and expanding their operating temperature range.

America's Justice Department "indicted the creators of an application that helps people spend their bitcoins anonymously," writes Reason.com: They're accused of "conspiracy to commit money laundering." Why "conspiracy to commit" as opposed to just "money laundering"?

Because they didn't hold anyone else's money or do anything illegal with it. They provided a privacy tool that may have enabled other people to do illegal things with their bitcoin... What this tool does is offer what's known as a "coinjoin," a method for anonymizing bitcoin transactions by mixing them with other transactions, as the project's founder, Keonne Rodriguez, explained to Reason in 2022: "I think the best analogy for it is like smelting gold," he said. "You take your Bitcoin, you add it into [the conjoin protocol] Whirlpool, and Whirlpool smelts it into new pieces that are not associated to the original piece."
Reason argues that providing the tool isn't a crime, just like selling someone a kitchen knife isn't a crime: The government's decision to indict Rodriguez and his partner William Lonergan Hill is also an attack on free speech because all they did was write open-source code and make it widely available. "It is an issue of a chilling effect on free speech," attorney Jerry Brito, who heads up the cryptocurrency nonprofit Coin Center, told Reason after the U.S. Treasury went after the creators of another piece of anonymizing software...

The most important thing about bitcoin, and money like it, isn't its price. It's the check it places on the government's ability to devalue, censor, and surviel our money. Creators of open-source tools like Samourai Wallet should be celebrated, not threatened with a quarter-century in a federal prison.

"One of the biggest mysteries in astrophysics today is that the forces in galaxies do not seem to add up," write two U.K. researchers in the Conversation: Galaxies rotate much faster than predicted by applying Newton's law of gravity to their visible matter, despite those laws working well everywhere in the Solar System. To prevent galaxies from flying apart, some additional gravity is needed. This is why the idea of an invisible substance called dark matter was first proposed. But nobody has ever seen the stuff. And there are no particles in the hugely successful Standard Model of particle physics that could be the dark matter — it must be something quite exotic.

This has led to the rival idea that the galactic discrepancies are caused instead by a breakdown of Newton's laws. The most successful such idea is known as Milgromian dynamics or Mond [also known as modified Newtonian dynamics], proposed by Israeli physicist Mordehai Milgrom in 1982. But our recent research shows this theory is in trouble...

Due to a quirk of Mond, the gravity from the rest of our galaxy should cause Saturn's orbit to deviate from the Newtonian expectation in a subtle way. This can be tested by timing radio pulses between Earth and Cassini. Since Cassini was orbiting Saturn, this helped to measure the Earth-Saturn distance and allowed us to precisely track Saturn's orbit. But Cassini did not find any anomaly of the kind expected in Mond. Newton still works well for Saturn... Another test is provided by wide binary stars — two stars that orbit a shared centre several thousand AU apart. Mond predicted that such stars should orbit around each other 20% faster than expected with Newton's laws. But one of us, Indranil Banik, recently led a very detailed study that rules out this prediction. The chance of Mond being right given these results is the same as a fair coin landing heads up 190 times in a row. Results from yet another team show that Mond also fails to explain small bodies in the distant outer Solar System...

The standard dark matter model of cosmology isn't perfect, however. There are things it struggles to explain, from the universe's expansion rate to giant cosmic structures. So we may not yet have the perfect model. It seems dark matter is here to stay, but its nature may be different to what the Standard Model suggests. Or gravity may indeed be stronger than we think — but on very large scales only.
"Ultimately though, Mond, as presently formulated, cannot be considered a viable alternative to dark matter any more," the researchers conclude. "We may not like it, but the dark side still holds sway."

A new battery from Energizer comes with "color alert technology" to alert parents if their child has swallowed one. When the coin lithium battery comes into contact with saliva, it activates a blue dye "so parents and caregivers know that medical attention could be required," reports the New York Times. The battery also features more secure packaging and a nontoxic bitter coating. From the report: The new coin lithium battery features more secure packaging, a nontoxic bitter coating to discourage swallowing and "color alert technology" that activates a blue dye when the battery comes into contact with moisture, like saliva, so parents and caregivers know that medical attention could be required. The new battery was announced in a video last week by Energizer and Trista Hamsmith, whose 18-month-old daughter died after swallowing a button battery from a remote control. Ms. Hamsmith founded a nonprofit organization focused on children's safety, successfully advocated for legislation, known as Reese's Law, that requires a secure compartment of the batteries in products that use them as well as stronger warning labels on all packaging, and is now working to make the batteries themselves safer.

Ingested coin or button batteries result in thousands of emergency hospital visits each year, according to the U.S. Consumer Product Safety Commission, which notes that "the consequences of a child swallowing a battery can be immediate, devastating and deadly." "A button cell battery can burn through a child's throat or esophagus in as little as two hours if swallowed," according to the agency. Secure packaging and bitter coatings for batteries have long existed, but "the massive breakthrough here is the color alert technology, which helps give caretakers that indicator that something has happened," Jeff Roth, the global category leader for batteries at Energizer, said in an interview on Wednesday. "The most significant part about this is getting help early in the process," he said. "That's really what the color alert technology allows the family to do."

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.

Harry McCracken, writing for FastCompany: Recently, Microsoft built a clock. Well, "built" may be overstating things. Members of the company's quantum computing team found a small digital clock in a wood case on Amazon -- the kind you might mistake for a nicer-than-usual trade show tchotchke. They hacked it to run off two experimental batteries they'd created in collaboration with staffers at the U.S. Department of Energy's Pacific Northwest National Laboratory (PNNL). Then they dressed up its enclosure by adding the logo of Azure Quantum Elements, the Microsoft platform for AI-enhanced scientific discovery that had been instrumental in developing the new battery technology.

The point of this little DIY project was to prove the batteries worked in a visceral way: "You want to have a wow moment," explains Brian Bilodeau, the head of partnerships, strategy, and operations for Azure Quantum. And the person the quantum team hoped to wow was Microsoft CEO Satya Nadella. Not that getting Nadella's attention was such a daunting prospect. Throwing vast amounts of Azure high-performance computing (HPC) resources at a big, hairy technical challenge such as materials research is the sort of challenge he's predisposed to take a personal interest in. Still, the tangible evidence of success made for a memorable moment: "I was very, very excited to see it come through," Nadella remembers.

The coin-sized CR2032 batteries powering the clock looked like the ones you might find in a pocket calculator or garage door opener. But on the inside, they used a solid-state electrolyte that replaces 70% of the lithium in garden-variety batteries with sodium. That holds the potential to address multiple issues with lithium batteries as we know them: their limited life on a charge, shrinking capacity over time, subpar performance in extreme temperatures, and risk of catching fire or even exploding. In addition, reducing lithium use in favor of cheap, plentiful sodium could be a boon to the fraught battery supply chain. With further development, the new material could benefit the myriad aspects of modern life that depend on batteries, from smartphones to EVs to the power grid. But Microsoft, being Microsoft, regards all this promise first and foremost as proof of Azure Quantum Elements' usefulness to the customers it's designed to serve. Unveiled last June, the cloud service is currently a "private preview" being tested by organizations such as Britain's Johnson Matthey, which is using it to help design catalytic converters and hydrogen fuel cells.

To celebrate the 30th anniversary of Doom, both John Romero and John Carmack are appearing now on a special 30th anniversary stream on Twitch. (Right now they're talking about people who got into professional networking careers because of what they'd learned from setting up multiplayer deathmatches...)

And earlier this morning, Romero shocked the gaming world by posting six words on X.

"Free WAD for SIGIL II is up"

The official page for the long-awaited new Doom episode promises a 2 megabyte file "packed with some hardcore classic DOOM punishment — beware of Ultra-Violence mode!" There's nine new maps with names like "Wrathful Reckoning" and "Vengeance Unleashed". And the site is also selling an upgrade with a THORR soundtrack — priced at €6.66 — along with t-shirts, boxed editions of the original game Sigil, and a "Megawad Beast Box" that's "individually numbered and signed personally by John Romero and featuring the artwork of Christopher Lovell" (including a signed art print).

Besides sundry extras including a t-shirt, stickers, and a Sigil-themed coin, it also comes with a pewter statue of John Romero's head on a spike...

The U.S. Court of Appeals for the D.C. Circuit has paved the way for bitcoin exchange-traded funds. From a report: On Tuesday, the court sided with Grayscale in a lawsuit against the Securities and Exchange Commission which had denied the company's application to convert the Grayscale Bitcoin Trust to an ETF. The decision could impact other companies that want to create bitcoin ETFs, like BlackRock and Fidelity. A spot bitcoin ETF would be traded through a traditional stock exchange, although the bitcoin would be held by a brokerage, and would allow investors to gain exposure to the world's biggest cryptocurrency without having to own the coin themselves. Many crypto bulls believe that approval of a spot bitcoin ETF will lead to more mainstream institutional adoption.

Bitcoin, ether and other major cap crypto coins surged on the news, and Coinbase, which is listed as the custodian partner in multiple spot bitcoin ETF applications, was up more than 14% on Tuesday. "The Commission failed to adequately explain why it approved the listing of two bitcoin futures ETPs but not Grayscale's proposed bitcoin ETP," the court said, referring to exchange-traded products. "In the absence of a coherent explanation, this unlike regulatory treatment of like products is unlawful." Grayscale Investments, which manages the world's biggest crypto fund, initiated its lawsuit against the SEC in June 2022 after the agency rejected its application to turn its flagship bitcoin fund, better known by its ticker GBTC, into an ETF. The company decided to pursue the ETF, which would be backed by bitcoin rather than bitcoin derivatives, after the SEC approved ProShares' futures-based bitcoin ETF in October 2021.

An anonymous reader quotes a report from Ars Technica: A new proposed class-action lawsuit (as noticed by Bloomberg Law) accuses user-generated "metaverse" company Roblox of profiting from and helping to power third-party websites that use the platform's Robux currency for unregulated gambling activities. In doing so, the lawsuit says Roblox is effectively "work[ing] with and facilitat[ing] the Gambling Website Defendants... to offer illegal gambling opportunities to minor users." The three gambling website companies named in the lawsuit -- Satozuki, Studs Entertainment, and RBLXWild Entertainment -- allow users to connect a Roblox account and convert an existing balance of Robux virtual currency into credits on the gambling site. Those credits act like virtual casino chips that can be used for simple wagers on those sites, ranging from Blackjack to "coin flip" games.

If a player wins, they can transfer their winnings back to the Roblox platform in the form of Robux. The gambling sites use fake purchases of worthless "dummy items" to facilitate these Robux transfers, according to the lawsuit, and Roblox takes a 30 percent transaction fee both when players "cash in" and "cash out" from the gambling sites. If the player loses, the transferred Robux are retained by the gambling website through a "stock" account on the Roblox platform. In either case, the Robux can be converted back to actual money through the Developer Exchange Program. For individuals, this requires a player to be at least 13 years old, to file tax paperwork (in the US), and to have a balance of at least 30,000 Robux (currently worth $105, or $0.0035 per Robux).

The gambling websites also use the Developer Exchange Program to convert their Robux balances to real money, according to the lawsuit. And the real money involved isn't chump change, either; the lawsuit cites a claim from RBXFlip's owners that 7 billion Robux (worth over $70 million) was wagered on the site in 2021 and that the site's revenues increased 10 times in 2022. The sites are also frequently promoted by Roblox-focused social media influencers to drum up business, according to the lawsuit. Roblox's terms of service explicitly bar "experiences that include simulated gambling, including playing with virtual chips, simulated betting, or exchanging real money, Robux, or in-experience items of value." But the gambling sites get around this prohibition by hosting their games away from Roblox's platform of user-created "experiences" while still using Robux transfers to take advantage of players' virtual currency balances from the platform. In a statement, Roblox said that "these are third-party sites and have no legal affiliation to Roblox whatsoever. Bad actors make illegal use of Roblox's intellectual property and branding to operate such sites in violation of our standards."

A Bloomberg investigative reporter wrote a new book titled Number Go Up: Inside Crypto's Wild Rise and Staggering Fall. This week Bloomberg published an excerpt that begins when the reporter received a flirtatious text message from a woman named Vicky Ho for a scam that's called "pig butchering".

"Vicky's random text had found its way to pretty much exactly the wrong target. I'd been investigating the crypto bubble for more than a year..." After a day, Vicky revealed her true love language: Bitcoin price data. She started sending me charts. She told me she'd figured out how to predict market fluctuations and make quick gains of 20% or more. The screenshots she shared showed that during that week alone she'd made $18,600 on one trade, $4,320 on another and $3,600 on a third... For days, she went on chatting without asking for me to send any money. I was supposed to be the mark, but I had to work her to con me.... Vicky sent me a link to download an app called ZBXS. It looked pretty much like other crypto-exchange apps. "New safe and stable trading market," a banner read at the top. Then Vicky gave me some instructions. They involved buying one cryptocurrency using another crypto-exchange app, then transferring the crypto to ZBXS's deposit address on the blockchain, a 42-character string of letters and numbers...

People around the world really were losing huge sums of money to the con. A project finance lawyer in Boston with terminal cancer handed over $2.5 million. A divorced mother of three in St. Louis was defrauded of $5 million. And the victims I spoke to all told me they'd been told to use Tether, the same coin Vicky suggested to me. Rich Sanders, the lead investigator at CipherBlade, a crypto-tracing firm, said that at least $10 billion had been lost to crypto romance scams.

The huge sums involved weren't the most shocking part. I learned that whoever was posing as Vicky was likely a victim as well — of human trafficking. Most "pig-butchering" operations were orchestrated by Chinese gangsters based in Cambodia or Myanmar. They'd lure young people from across Southeast Asia to move abroad with the promise of well-paying jobs in customer service or online gambling. Then, when the workers arrived, they'd be held captive and forced into a criminal racket. Thousands have been tricked this way. Entire office towers are filled with floor after floor of people sending spam messages around the clock, under threat of torture or death.

With the assistance of translators, I started video chatting with people who'd escaped...

I'd heard that [southwestern Cambodia's giant building complex] Chinatown alone held as many as 6,000 captive workers like "Vicky Ho."
Two of the workers interviewed "said they'd seen workers murdered." And another worker said Tether was used specifically because "It's more safe. We are afraid people will track us... It's untraceable."

The reporter's conclusion? "It was hard to see how this slave complex could exist without cryptocurrency."
