Google is confronting an existential threat as the U.S. government tries to break up the company as punishment for turning its revolutionary search engine into an illegal monopoly. From a report: The drama began to unfold Monday in a Washington courtroom as three weeks of hearings kicked off to determine how the company should be penalized for operating a monopoly in search. In its opening arguments, federal antitrust enforcers also urged the court to impose forward-looking remedies to prevent Google from using artificial intelligence to further its dominance. "This is a moment in time, we're at an inflection point, will we abandon the search market and surrender them to control of the monopolists or will we let competition prevail and give choice to future generations," said Justice Department attorney David Dahlquist.

The proceedings, known in legal parlance as a "remedy hearing," are set to feature a parade of witnesses that includes Google CEO Sundar Pichai. The U.S. Department of Justice is asking a federal judge to order a radical shake-up that would ban Google from striking the multibillion dollar deals with Apple and other tech companies that shield its search engine from competition, share its repository of valuable user data with rivals and force a sale of its popular Chrome browser. Google's attorney, John Schmidtlein, said in his opening statement that the court should take a much lighter touch. He said the government's heavy-handed proposed remedies wouldn't boost competition but instead unfairly reward lesser rivals with inferior technology. "Google won its place in the market fair and square," Schmidtlein said.

Boeing is seeking to withdraw an earlier agreement to plead guilty in a long-running criminal case that blamed the company for deceiving regulators before two deadly crashes of 737 MAX jets, WSJ is reporting, citing people familiar with the matter. From the report: The aerospace giant is seeking more lenient treatment from the Justice Department, which under the Trump administration is reviewing numerous pending criminal cases that haven't yet gone to trial or been approved by courts. Boeing nearly sealed its fate last year, agreeing in July to plead guilty to defrauding the Federal Aviation Administration. But a federal judge in Texas rejected the proposed deal in December, pushing the resolution beyond the Biden administration.

Now Boeing stands to benefit from fresh eyes at Trump's Justice Department, which is inclined to at least modify parts of the agreement, some of the people said. Allowing Boeing to rescind its plea agreement, or lightening the company's punishment, would mark one of the most prominent examples of the Trump administration's lighter-touch approach to some white-collar enforcement. There were 346 people killed in the two 737 MAX crashes, in 2018 and 2019. The two sides are still negotiating how to propose changes to the deal, expected by April 11, to U.S. District Judge Reed O'Connor, who oversees the case. One possible change under discussion: whether Boeing can forgo hiring an outside monitor to ensure its compliance with the law, the people said.

"Engineers have showcased a prototype electric vehicle that can drive for up to 40 miles (64 kilometers) per day using just solar power," reports LiveScience. The production-ready "Aptera Launch Edition" made its first appearance this month at CES 2025, and "also offers up to 400 miles (640 km) of range from a single charge via an electrical output, company representatives said in a statement."

LiveScience describes the vehicle as "lighter and more energy-efficient than conventional EVs, while offering a 50% reduction in aerodynamic resistance," with an energy efficiency rating of 100 Watt-hours per mile (Wh/mile). By contrast, a Tesla Model S (released in 2022) consumes 194 Wh/mile in the city in mild weather and 288 Wh/mile on the highway in mild weather, according to the EV Database. At a maximum range of 440 miles — including 40 miles using solar power and 400 miles using electricity — the Aptera EV may also overtake the current longest-range vehicles in production. The Mercedes-Benz EQS 450+ has a maximum range of 425 miles (684 km), according to the EV Database, followed by the Lucid Air Grand Touring at 410 miles (660 km).
Aptera says it's raised $135 million "through equity crowdfunding" to fund its pre-production progress. "Since its launch, the Company has accepted $1.7 billion in pre-orders with nearly 50,000 vehicles reserved by future Aptera owners in the U.S. and internationally."

MotorTrend writes that "nearly two decades in the making, the otherworldly three-wheel Aptera is headed to production this year as a $40,000, 400-mile EV that can capture up to 40 miles worth of free solar energy every day. Maybe." The California startup made similar promises in 2008, 2009, 2012, and 2022 and yet it has never delivered a single vehicle. Is anything different this time...?

At CES, co-CEO (and one of Aptera's original founders) Chris Anthony told MotorTrend it will take another $60 million to finish the development work, buy the tooling, and build out the Carlsbad, California, assembly plant. "We're still in fundraising mode and we hope that we inspire some people in this beautiful building (Las Vegas Convention Center) to invest in Aptera," Anthony said. "We're trying to raise $20 million in the first quarter of this year. That will basically kick off all the long-lead items to get into production, but it's a $60 million plan to get into volume production." Anthony said the company has already made one of its largest purchases, the molds for the carbon-fiber sheet-molding composite body structure and the fiberglass sheet-molding composite body panels that will be made in Italy. The next $20 million will cover the tooling for the diecast metal suspension arms and the injection-molded interior components...

It would be relatively easy for Aptera to hand build cars in a garage and announce the start of production, but the plan calls for building up to 80 cars per day per the guidance of engineering consultant and YouTuber Sandy Munro, who is an Aptera investor and adviser. "He really helped shepherd the design from what was an early prototype prove-out design into how to make the most manufacturable vehicle ever," Anthony said. The structure is built from just six parts and the entire car has been designed to be put together in a factory with just 12 stations. But that radical simplicity complicates the job at hand right now. In addition to developing the car, the small engineering team also has to create the machine that makes it. Anthony's plan has the factory ramping up to build 20,000 vehicles a year within nine months of starting production at the end of 2025.

Before that can happen, Aptera needs to clear the same hurdle that tripped it up in 2011 and sent the company stumbling into liquidation — the money. "We would love one investor to be so inspired by what we're doing that they just hand us a $60 million check," Anthony told MotorTrend. "But it could be something that's kind of piecemeal over the next nine months to get that $60 million into the company." Are you convinced?

Though it breaks down faster than CO2, methane is a greenhouse gas over 80 times as potent as carbon dioxide, reports the Washington Post. It suddenly started increasing in the atmosphere in 2007 — and then in 2020, its growth rate doubled.

While scientists have suspected it was natural gas, some researchers have a new theory... "The changes that we saw in the last couple of years — and even since 2007 — are microbial," said Sylvia Michel, lead author of the paper published last month in the Proceedings of the National Academy of Sciences. "Wetlands, if they are getting warmer and wetter, maybe they're producing more methane than they used to...."

Michel and her co-authors analyzed samples of methane, or CH4, from 22 sites around the globe at a Colorado laboratory. Then they measured the "heaviness" of that methane — specifically, how many of the molecules had a heavier isotope of carbon in them, known as C13. Different sources of methane give off different carbon signatures. Methane produced by microbes — mostly single-celled organisms known as archaea, which live in cow stomachs, wetlands and agricultural fields — tends to be "lighter," or have fewer C13 atoms. Methane from fossil fuels, on the other hand, is heavier, with more C13 atoms. As the amount of methane has risen in the atmosphere over the past 15 years, it's also gotten lighter and lighter. The scientists used a model to analyze those changes and found that only large increases in microbial emissions could explain both the rising methane and its changing weight....

Researchers say it doesn't mean that the world can just keep burning natural gas. If wetlands are releasing methane faster than ever, they argue, there should be an even greater push to curb methane from the sources humans can control, such as cows, agriculture and fossil fuels.
The article includes this quote from Stanford University professor Rob Jackson (who works on the Global Methane Budget, a project tracking the world's methane sources). "You can turn a wrench in an oil and gas field to quench methane emissions," Jackson said. "There's no wrench for the Congo or the Amazon." Another recent study found that two-thirds of current methane emissions are caused by humans — from fossil fuels, rice cultivation, reservoirs and other sources. "Methane forms biologically in warm, wet, low-oxygen environments," Jackson said. "The wetlands of a rice paddy and the gut of the cow are all similar." But evidence is also emerging that natural wetlands may be responding to warming temperatures by pumping out more methane. Satellite data from recent years has shown global methane hot spots in the tropical wetlands of the Amazon and the Congo. "Wetlands will emit more methane as temperatures warm," Jackson said. "This may be the start of a reinforcing feedback, that higher temperatures release more methane from natural ecosystems...."

Over 100 countries have pledged to reduce their methane emissions by 30 percent by 2030, compared with 2020 levels — but so far, that pledge has yet to see results. Instead, satellite measurements show concentrations are rising at a rate that is in line with the worst-case climate scenarios.

Scientists have finally detected and measured the ambipolar field, a weak electric field surrounding Earth that was first theorized over 60 years ago. "Any planet with an atmosphere should have an ambipolar field," says astronomer Glyn Collinson of NASA's Goddard Space Flight Center. "Now that we've finally measured it, we can begin learning how it's shaped our planet as well as others over time." ScienceAlert reports: Here's how the ambipolar field was expected to work. Starting at an altitude of around 250 kilometers (155 miles), in a layer of the atmosphere called the ionosphere, extreme ultraviolet and solar radiation ionizes atmospheric atoms, breaking off negatively charged electrons and turning the atom into a positively charged ion. The lighter electrons will try to fly off into space, while the heavier ions will try to sink towards the ground. But the plasma environment will try to maintain charge neutrality, which results in the emergence of an electric field between the electrons and the ions to tether them together. This is called the ambipolar field because it works in both directions, with the ions supplying a downward pull and the electrons an upward one. The result is that the atmosphere is puffed up; the increased altitude allows some ions to escape into space, which is what we see in the polar wind.

This ambipolar field would be incredibly weak, which is why Collinson and his team designed instrumentation to detect it. The Endurance mission, carrying this experiment, was launched in May 2022, reaching an altitude of 768.03 kilometers (477.23 miles) before falling back to Earth with its precious, hard-won data. And it succeeded. It measured a change in electric potential of just 0.55 volts -- but that was all that was needed. "A half a volt is almost nothing -- it's only about as strong as a watch battery," Collinson says. "But that's just the right amount to explain the polar wind." That amount of charge is enough to tug on hydrogen ions with 10.6 times the strength of gravity, launching them into space at the supersonic speeds measured over Earth's poles. Oxygen ions, which are heavier than hydrogen ions, are also lofted higher, increasing the density of the ionosphere at high altitudes by 271 percent, compared to what its density would be without the ambipolar field. The findings have been published in the journal Nature.

According to The Information (paywalled), Meta plans to ship an extremely light mixed reality headset in 2027, codenamed Puffin. It follows a report that the company canceled a high-end headset planned for the same year, which previous reports speculated as being a Quest Pro 2. UploadVR reports: Puffin reportedly resembles "a bulky pair of glasses" and weighs less than 110 grams, yet is an opaque VR-style headset with pancake lenses and passthrough cameras. Its remarkably light weight is apparently being achieved by offloading both the battery and computing hardware to an external tethered puck, which Meta "hopes" will be small enough to fit in the user's pocket.

If the report is accurate, Puffin will be significantly lighter than any other shipping fully functional VR headset to date. For comparison, Meta Quest 3 weighs around 400 grams without its straps and facial interface and around 515 grams with them. Of this weight, the battery is around 70 grams. The report describes Puffin as not including controllers, instead using the gaze-and-pinch input scheme introduced by Apple Vision Pro.

IKEA is expanding its stock-counting drone system to operate alongside workers in the U.S., starting with its Perryville, Maryland distribution center. The Verge reports: The Verity-branded drones also come with a new AI-powered system that allows them to fly around warehouses 24/7. That means they'll now operate alongside human workers, helping to count inventory as well as identify if something's in the wrong spot. Previously, the drones only flew during nonoperational hours. Parag Parekh, the chief digital officer for Ikea retail, says in the press release that flights are prescheduled and that the drones use a "custom indoor positioning system to navigate higher levels of storage locations." They also have an obstacle detection system that allows them to reroute their paths to avoid collisions. Ikea is also working on several upgrades for the drones, including the ability to inspect unit loads and racks.

So far, Ikea's fleet consists of more than 250 drones operating across 73 warehouses in nine countries. Ikea first launched its drone system in partnership with Verity in 2021 and expanded it to more locations throughout Europe last year. Now, Ikea plans on bringing its AI-upgraded drones to more distribution centers in Europe and North America, which the company says will help "reduce the ergonomic strain on [human] co-workers, allowing them to focus on lighter and more interesting tasks."

"Samsung's latest solid-state battery technology will power up premium EVs first, giving them up to 621 miles of range," writes PC Magazine: The new batteries — which promise to improve vehicle range, decrease charging times, and eliminate risk of battery fires — could go into mass production as soon as 2027. Multiple automakers have been reportedly testing samples. Samsung did not list any by name but it's worked with Hyundai, Stellantis, and General Motors, among others. "We supplied samples to customers from the end of last year to the beginning of this year and are receiving positive feedback," Samsung SDI VP Koh Joo-young said at SNE Battery Day 2024 in Seoul, according to Korean outlet The Elec and translated by Google.

Perhaps unsurprisingly, the batteries won't be cheap. They will initially go in "super premium EVs" and will offer 900 to 1,000 kilometers (559-621 miles) of range and improved safety... Samsung's presentation also reiterated previously announced plans to create batteries that can charge in nine minutes and last 20 years by 2029.
More details from Notebookcheck: According to Samsung SDI's VP, automakers are interested in its solid-state battery packs because they are smaller, lighter, and much safer than what's in current electric cars. Apparently, they are also rather expensive to produce, since it warns that they will first go into the "super premium" EV segment. Those Samsung defines as luxury electric cars that can cover more than 600 miles on a charge.

Samsung's oxide solid-state battery technology is rated for an energy density of about 500 Wh/kg, which is about double the density of mainstream EV batteries. Those have capacities that already allow more than 300 miles on a charge, so 600 miles of range in a similar footprint is not out of the question, but the issue is production costs.

Lenovo's widely used ThinkPad laptop hasn't changed much over the years. Corporate technology leaders say that's why they love it. From a report: "There's a lot to be said for familiarity and that consistent experience," said Ace Hardware Chief Information Officer Rick Williams, whose company uses about 4,000 ThinkPads. The ThinkPad brand of personal computers, originally created by International Business Machines, hit the market in 1992 before Lenovo acquired it, along with IBM's PC division, in 2005. Since then, the boxy design -- originally inspired by the Japanese bento box -- has gotten thinner and lighter, but not much else has changed from a design perspective, Lenovo said.

The logo is the same, although in 2005 Lenovo did add the red dot over the "i" in "Think" that remains today. That logo has remained angled at 37 degrees on the device. And on the keyboard the small, red, old-timey trackpoint remains nestled between the "B," "G" and "H" keys (which Lenovo says some users swear by and some CIOs say they never use). Ports and camera placement have also been relatively consistent. And despite some experimentation with colors, the laptop itself primarily remains its original black. "You're going to recognize the iconic ThinkPad," said Tom Butler, executive director for worldwide commercial portfolio and product management at Hong Kong-based Lenovo.

Its strategy might seem counterintuitive in an industry where winners and losers are often determined based on their pace of innovation, and where to stay the same often means to become obsolete. Big consumer tech companies that dominated the early 2000s, like BlackBerry, Nokia and Motorola, ultimately couldn't keep pace with competitors and struggled. But for Lenovo, which plays in the enterprise space, it's paying off. Lenovo has been leading in market share in the worldwide personal computer vendor market, based on unit shipments, on and off for more than 10 years, according to research firm Gartner.

Scientists studying lunar samples brought back by the Apollo missions have determined that the moon's thin atmosphere is produced largely by meteorite impacts. "Our findings provide a clearer picture of how the moon's surface and atmosphere interact over long timescales, [and] enhance our understanding of space weathering processes," said Dr Nicole Nie, the co-author of the new study based at MIT's department of Earth, atmospheric, and planetary sciences. The Guardian reports: Writing in the journal Science Advances, Nie and her colleagues describe how the lunar atmosphere must be constantly replenished because its atoms are continuously being lost to space, primarily because of the moon's weak gravity, or trapped on the lunar surface. Ultraviolet photons from the sun can rerelease the latter, but the researchers say replenishment of the atmosphere is thought to rely on atoms being released from within lunar minerals -- either via vaporisation by meteorite impacts, or by solar wind sputtering, a process in which charged particles from the sun hit the moon and eject atoms. But which of the two factors dominates had been unclear, with data from Nasa's lunar atmosphere and dust environment explorer, launched in 2013, suggesting both were at play.

Nie and colleagues unpicked the conundrum by studying the different forms, or isotopes, of potassium and rubidium in 10 samples of lunar soil from the Apollo missions. The team say meteorite impacts and solar wind sputtering both favor the release of lighter forms of the elements, but that the actual proportion of heavy to light isotopes that end up in the lunar atmosphere and soil would differ depending on the process. "After measuring the isotopic compositions of lunar soils, we built a mathematical model taking into account various space weathering processes, and solve for the contribution of each of them by matching the measured isotopic compositions," said Nie. The results suggest about 70% of the moon's atmosphere is down to impact vaporization and 30% to solar wind sputtering.

"The linked article is pretty much a press release, but it's still interesting to see the promise of exoskeletons starting to infiltrate the mass market," writes longtime Slashdot reader Baron_Yam. "These rigs cost $5,000, weigh only a few pounds, and go for multiple hours on a charge." Gizmodo reports: With the MO/GO exoskeleton hiking pants, a traipse through the mountains is becoming more mechanical, not to mention expensive. The MO/GO (short for "Mountain Goat") is a joint effort with established outdoor apparel makers Arc'Teryx and the tech startup Skip. Remember Samsung's exoskeleton pants concepts? These are kind of like that, though Skp and Arc'Teryx's first commercial product covers up all those glaring metal bits with an already-pricey pair of designer hiking pants. The MO/GO is supposed to push you 40% harder, according to the company. What does that mean in context? Fast Company rolled around in them for a hike and found the exoskeleton took a lot of weight off the knee, cushioned footfalls, and kicked the leg forward when tackling an incline. [...]

Two braces go into each leg, while the 3-hour power pack sits at the belt line just above your posterior. The MO/GO is a pair of Arc'teryx Gamma pants with cuffs to snap Skip's carbon fiber exoskeletal thighs onto the outside of each leg, which should impact your quadriceps and hamstring muscles. The companies claim each ligament weighs 2 pounds, with the pants in total clocking in at 7 pounds, but instead of adding weight the arms absorb the impact of each step, enough to make users feel "30 pounds lighter." [...] On Skip's site, you can see an internal look at how the motors spin every time the user raises their knee. The pants are supposed to have an on-board algorithm to handle stairs or a steep incline differently. You don't control it with an app either. There are three buttons on the pants: an on/off switch, as well as "less assistance" and "more assistance" toggles.

An anonymous reader quotes a report from Reuters: Europe's landmark rules on artificial intelligence will enter into force next month after EU countries endorsed on Tuesday a political deal reached in December, setting a potential global benchmark for a technology used in business and everyday life. The European Union's AI Act is more comprehensive than the United States' light-touch voluntary compliance approach while China's approach aims to maintain social stability and state control. The vote by EU countries came two months after EU lawmakers backed the AI legislation drafted by the European Commission in 2021 after making a number of key changes. [...]

The AI Act imposes strict transparency obligations on high-risk AI systems while such requirements for general-purpose AI models will be lighter. It restricts governments' use of real-time biometric surveillance in public spaces to cases of certain crimes, prevention of terrorist attacks and searches for people suspected of the most serious crimes. The new legislation will have an impact beyond the 27-country bloc, said Patrick van Eecke at law firm Cooley. "The Act will have global reach. Companies outside the EU who use EU customer data in their AI platforms will need to comply. Other countries and regions are likely to use the AI Act as a blueprint, just as they did with the GDPR," he said, referring to EU privacy rules.

While the new legislation will apply in 2026, bans on the use of artificial intelligence in social scoring, predictive policing and untargeted scraping of facial images from the internet or CCTV footage will kick in in six months once the new regulation enters into force. Obligations for general purpose AI models will apply after 12 months and rules for AI systems embedded into regulated products in 36 months. Fines for violations range from $8.2 million or 1.5% of turnover to 35 million euros or 7% of global turnover depending on the type of violations.

This year Dell moved to soldered RAM for its XPS 14 and 16, writes Digital Trends, which "makes it impossible to upgrade, or even repair."

"This was a big change from the past, where the XPS 15 and 17 were both celebrated for their upgradability." Of course, Dell isn't the first to make the transition. In fact, they're one of the last, which is what makes the decision so much tougher to swallow. Where soldered RAM was previously limited to just MacBooks and ultrabooks, it's now affecting most high-performance laptops for gaming as well. Even the fantastic ROG Zephyrus G14 moved to soldered memory this year.
After two months of research, the article's author acknowledges "there are tangible benefits to companies using soldered RAM, and all the people I spoke to while writing this agree that they outweigh the downsides, but how that applies to the end-user is a bit more complicated." If there's one thing and one thing only that soldered RAM is indisputably good for, it's saving space. [Haval Othman, a senior director of experience engineering at HP] explained the benefits, saying: "If battery life, mobility, form factor (thin and light), and power efficiency are my priority among other design choices, then my mind immediately goes to soldered RAM; because that's where soldered RAM can be beneficial and power-efficient, which will lead to longer battery life. Plus, it's going to give me more space on the motherboard, so I can design the product thinner and lighter. [...] If we want a thin product, the trade-off is soldering more of the devices onto the board."

This tracks. In a laptop, there's only so much space that can be used for components, and that free space grows smaller by the year to make ultrabooks possible. They're an industrywide trend that was first popularized by Apple, and the rest of the laptop manufacturing world quickly caught on. Each year, laptops are released thinner and lighter, and that means having to squeeze the components together in new, innovative ways... Soldering the memory down onto the motherboard means that it can be attached almost anywhere within the laptop instead of being slotted into a specific part of it. It effectively makes the laptop thinner by cutting back on the space that the RAM module takes up. The space saved by soldering memory can be used for other things, such as a bigger battery....

All three companies that I spoke to stress the form factor much more than any tangible cost benefits... Stuart Gill, director of global media relations, campaigns, and corporate content [said] "Both soldered and socketed RAM designs are now quite mature. As a result, we see no impact on the manufacturing process and, therefore, the cost to the consumer."
SO-DIMM chips also have "relatively limited bandwidth," according to HP's Othman, "while when you solder the memory chips onto the board, you can build it for a much wider bandwidth."

But the article ends by looking to the future. "The good news is that SO-DIMM memory might eventually be replaced by the CAMM2 standard." Recently approved by JEDEC, CAMM2 is said to be significantly thinner, and it'll be available both in soldered and non-soldered variants. Using CAMM2 will allow laptops to stack up to 128GB of RAM, and the frequencies are said to be going up, too. CAMM2 can also activate dual-channel memory with just a single module.

The co-founder of Silicon Valley-based software testing startup HeadSpin was sentenced Friday to 18 months in prison and a $1 million fine, reports SFGate — for defrauding investors. Lachwani pleaded guilty to two counts of wire fraud and a count of securities fraud in April 2023, after federal prosecutors accused him of, for years, lying to investors about HeadSpin's finances to raise more money. HeadSpin, founded in 2015, grew to a $1.1 billion valuation by 2020 with over $115 million in funding from investors including Google Ventures and Iconiq Capital... He had personally altered invoices, lied to the company accountant and sent slide decks with fraudulent information to investors, [according to the government's 2021 criminal complaint]...

Breyer, per the New York Times, rejected Lachwani's lawyer's argument that because HeadSpin investors didn't end up losing money, he should receive a light sentence. The judge, who often oversees tech industry cases, reportedly said: "If you win, there are no serious consequences — that simply can't be the law." Still, the sentencing was far lighter than it could have been. The government's prosecuting attorneys had asked for a five-year prison term.
The New York Times reported in December that HeadSpin's financial statements had "often arrived months late, if at all, investors said in legal declarations," while the company's financial department "consisted of one external accountant who worked mostly from home using QuickBooks." And the comnpany also had no human resources department or organizational chart... After Manish Lachwani founded the Silicon Valley software start-up HeadSpin in 2015, he inflated the company's revenue numbers by nearly fourfold and falsely claimed that firms including Apple and American Express were customers. He showed a profit where there were losses. He used HeadSpin's cash to make risky trades on tech stocks. And he created fake invoices to cover it all up.

What was especially breathtaking was how easily Mr. Lachwani, now 48, pulled all that off... [HeadSpin] had no chief financial officer, had no human resources department and was never audited. Mr. Lachwani used that lack of oversight to paint a rosier picture of HeadSpin's growth. Even though its main investors knew the start-up's financials were not accurate, according to Mr. Lachwani's lawyers, they chose to invest anyway, eventually propelling HeadSpin to a $1.1 billion valuation in 2020. When the investors pushed Mr. Lachwani to add a chief financial officer and share more details about the company's finances, he simply brushed them off. These details emerged this month in filings in U.S. District Court for the Northern District of California after Mr. Lachwani had pleaded guilty to three counts of fraud in April...

The absence of controls at HeadSpin is part of an increasingly noticeable pattern at Silicon Valley start-ups that have run into trouble. Over the past decade, investors in tech start-ups were so eager to back hot companies that many often overlooked reckless behavior and gave up key controls like board seats, all in the service of fast growth and disruption. Then when founders took the ethos of "fake it till you make it" too far, their investors were often unaware or helpless...

Now, amid a start-up shakeout, more frauds have started coming to light. The founder of the college aid company Frank has been charged, the internet connectivity start-up Cloudbrink has been sued, and the social media app IRL has been investigated and sued. Last month, Mike Rothenberg, a Silicon Valley investor, was found guilty on 21 counts of fraud and money laundering. On Monday, Trevor Milton, founder of the electric vehicle company Nikola, was sentenced to four years in prison for lying about Nikola's technological capabilities.
The Times points out that similarly, FTX only had a three-person board "with barely any influence over the company, tracked its finances on QuickBooks and used a small, little-known accounting firm." And that Theranos had no financial audits for six years.

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.

Gen Z is reviving the trend of reading physical books over digital ones, with a notable increase in library visits and book purchases, as evidenced by celebrities like Kaia Gerber and Kendall Jenner promoting literature and book clubs. The Guardian reports: This week the 22-year-old model Kaia Gerber launched her own book club, Library Science. Gerber, who this month appears on the cover of British Vogue alongside her supermodel mum, Cindy Crawford, describes it as "a platform for sharing books, featuring new writers, hosting conversations with artists we admire -- and continuing to build a community of people who are as excited about literature as I am." "Books have always been the great love of my life," she added. "Reading is so sexy."

Gerber isn't alone. Last year in the UK 669m physical books were sold, the highest overall level ever recorded. Research from Nielsen BookData highlights that it is print books that gen Z favour, accounting for 80% of purchases from November 2021 to 2022. Libraries are also reporting an uptick in gen Z users who favour their quiet over noisy coffee shops. In the UK in-person visits are up 71%. While the BookTok charts -- a subsection of TikTok where avid readers post recommendations -- are regularly topped by fantasy and romance titles from authors such as Colleen Hoover, gen Z are reading a diverse range of genres.

"Overall we are seeing a move towards escapism through the rise in speculative fiction, romance and fantasy, but I think it would be a mistake to homogenise gen Z and say they're reading lighter," says the author and literary agent Abigail Bergstrom. "With the oversaturation and noise of the wild west digital landscape, they are also demanding higher standards, especially when it comes to the authority and expertise of a writer on a particular subject."

Parisians have approved a steep rise in parking rates for SUVs in the French capital. The proposals were approved by 54.55% of voters, but turnout was only about 5.7%. From a report: The move triples parking rates for cars weighing 1.6 tonnes or more to $20 an hour in inner Paris. The vote was called by Socialist Mayor Anne Hidalgo, who has argued that SUVs are dangerous and bad for the environment. About 1.3m residents of central Paris were eligible to vote. However they will not be affected by the result as street-parking for local residents will remained unchanged. The move is mainly aimed at people from the suburbs who drive into the centre of the capital for the day.

There are exemptions for fully electric cars, taxi drivers, tradespeople, health workers and people with disabilities. Ms Hidalgo has been in office for almost 10 years. Under her tenure as mayor, many Paris streets, including the banks of the river Seine, have been pedestrianised. An extensive network of cycle lanes has also been built, in an effort to discourage driving. Environmentalists argue that SUVs consume more fuel than other cars and that their construction and use produce more harmful emissions. Supporters of the move also note that tall vehicles are deadlier than lighter cars when they are involved in accidents.

For the first time, scientists have discovered nuclear fission occurring amongst the stars, supporting the idea that neutron stars create "superheavy" elements when they collide, which then break down via nuclear fission to birth rare elements. Space.com reports: Nuclear fission is basically the opposite of nuclear fusion. While nuclear fusion refers to the smashing of lighter elements to create heavier elements, nuclear fission is a process that sees energy released when heavy elements split apart to create lighter elements. Nuclear fission is pretty well known, too. It's actually the basis of energy-generating nuclear power plants here on Earth -- however, it had not been seen occurring amongst the stars before now.

The team of researchers led by North Carolina State University scientist Ian Roederer searched data concerning a wide range of elements in stars to discover the first evidence that nuclear fission could therefore be acting when neutron stars merge. These findings could help solve the mystery of where the universe's heavy elements come from. Scientists know that nuclear fusion is not just the primary source of energy for stars, but also the force that forges a variety of elements, the "heaviest" being iron.

The evidence of nuclear fission discovered by [Matthew Mumpower, research co-author and a scientist at Los Alamos National Laboratory] and the team comes in the form of a correlation between "light precision metals," like silver, and "rare earth nuclei," like europium, showing in some stars. When one of these groups of elements goes up, the corresponding elements in the other group also increases, the scientists saw. The team's research also indicates that elements with atomic masses -- counts of protons and neutrons in an atomic nucleus -- greater than 260 may exist around neutron star smashes, even if this existence is brief. This is much heavier than many of the elements at the "heavy end" of the periodic table. "The only plausible way this can arise among different stars is if there is a consistent process operating during the formation of the heavy elements," Mumpower said. "This is incredibly profound and is the first evidence of fission operating in the cosmos, confirming a theory we proposed several years ago."

"As we've acquired more observations, the cosmos is saying, 'hey, there's a signature here, and it can only come from fission.'"

The research was published in the journal Science.

Tech YouTuber Dave Lee provided a hands-on first look at the new PlayStation 5 "slim" and gave a preview of how it looks compared to the original 2020 launch versions. Kotaku reports: One of his biggest takeaways is that the console, while lighter, doesn't necessarily feel that much smaller in contrast to initial predictions. Maybe that's why Sony's not officially marketing the new device as a "slim" version. From there, Lee runs through some of the less obvious changes. A few we already knew about like the USB-a slot on the front being replaced by two USB-c ports, as well as the t side panels split into two pieces to accommodate the new detachable disc drive. Lee actually showed how the disc drive comes out, and it looks really simple and convenient. There's no screws involved. Instead, putting pressure on a tab releases it from the housing while a socket near the bottom is how it plugs into the rest of the console.

Less neat are the new see-thru plastic pegs that stabilize the console when it's laid horizontal. While they've been added to help secure the PS5 given its new detachable disc drive design, Lee was unimpressed. I kind of agree. They're not a very elegant solution. The same goes for the divided panels themselves. I didn't realize this before, but they actually have different finishes. The bottom is a matte white that's a little different from the current PS5 plates and the top has a glossy finish.

Inside the new PS5, Lee pointed out a handful of differences. The top heat exhaust is less stylized, with plain vents instead of a snail shell like spiral. The internal SSD unit layout is also different. That's the piece that powers the PS5's lighting-quick load speeds, and it's not yet clear if the new design will impact performance at all. Lee's initial testing showed there was no real difference. It will also be interesting to see how the new PS5s deal with heat given its the same CPU running in a smaller layout.

Richard Tribou reports via Phys.Org: NASA's goal to reduce the costs of the powerful Space Launch System rocket for its Artemis program by 50% was called "highly unrealistic" and a threat to its deep space exploration plans, according to a report by NASA's Office of the Inspector General released (PDF) on Thursday. The audit says the costs to produce one SLS rocket through its proposed fixed-cost contract will still top $2.5 billion, even though NASA thinks it can shrink that through "workforce reductions, manufacturing and contracting efficiencies, and expanding the SLS's user base."

"Given the enormous costs of the Artemis campaign, failure to achieve substantial savings will significantly hinder the sustainability of NASA's deep space human exploration efforts," the report warns. The audit looked at NASA's plans to shift from its current setup among multiple suppliers for the hardware to a sole-sourced services contract that would include the production, systems integration and launch of at least five SLS flights beginning with Artemis V currently slated for as early as 2029. NASA's claim it could get those costs to $1.25 billion per rocket was taken to task by the audit.

"NASA's aspirational goal to achieve a cost savings of 50% is highly unrealistic. Specifically, our review determined that cost saving initiatives in several SLS production contracts were not significant," the audit reads. It does find that rocket costs could approach $2 billion through the first 10 SLS rockets under the new contract, a reduction of 20%. [...] Through 2025, the audit stated its Artemis missions will have topped $93 billion, which includes billions more than originally announced in 2012 as years of delays and cost increases plagued the leadup to Artemis I. The SLS rocket represents 26% of that cost to the tune of $23.8 billion. The inspector general makes several recommendations to NASA. The most striking of which is that NASA consider using commercial heavy-lift rockets, such as SpaceX's Starship and Super Heavy or Blue Origin's New Glenn, as an alternative to the SLS rocket for future Artemis missions.

"Although the SLS is the only launch vehicle currently available that meets Artemis mission needs, in the next 3 to 5 years other human-rated commercial alternatives that are lighter, cheaper, and reusable may become available," the audit reads. "Therefore, NASA may want to consider whether other commercial options should be a part of its mid- to long-term plans to support its ambitious space exploration goals."
