Automattic CEO and WordPress co-creator Matt Mullenweg unleashed a scathing attack on a rival firm this week, calling WP Engine -- a managed WordPress hosting provider that has raised nearly $300 million in funding over its 14-year history -- a "cancer to WordPress." From a report: Mullenweg criticized the company -- which has been commercializing the open source WordPress project since 2010 -- for profiteering without giving much back, while also disabling key features that make WordPress such a powerful platform in the first place. [...] But speaking last week at WordCamp US 2024, a WordPress-focused conference held in Portland, Oregon, Mullenweg pulled no punches in his criticism of WP Engine. Taking to the stage, Mullenweg read out a post he had just published to his personal blog, where he points to the distinct "five for the future" investment pledges made by Automattic and WP Engine to contribute resources to support the sustained growth of WordPress, with Automattic contributing 3,900 hours per week, an WP Engine contributing just 40 hours. While he acknowledged that these figures are just a "proxy," and might not be perfectly accurate, Mullenweg said that this disparity in contributions is notable, as both Automattic and WP Engine "are roughly the same size, with revenue in the ballpark of half-a-billion [dollars]." [...] Mullenweg published a follow up blog post, where he calls WP Engine a "cancer" to WordPress. "It's important to remember that unchecked, cancer will spread," he wrote. "WP Engine is setting a poor standard that others may look at and think is ok to replicate."

The US Commerce Department on Monday will propose a ban on the sale or import of smart vehicles that use specific Chinese or Russian technology because of national security concerns, according to US officials. From a report: A US government investigation that began in February found a range of national security risks from embedded software and hardware from China and Russia in US vehicles, including the possibility of remote sabotage by hacking and the collection of personal data on drivers, Secretary of Commerce Gina Raimondo told reporters Sunday in a conference call. "In extreme situations, a foreign adversary could shut down or take control of all their vehicles operating in the United States, all at the same time, causing crashes (or) blocking roads," she said. The rule would not apply to cars already on the road in the US that already have Chinese software installed, a senior administration official told CNN. The software ban would take effect for vehicles for "model year" 2027 and the hardware ban for "model year" 2030, according to the Commerce Department. The proposed regulatory action is part of a much broader struggle between the United States and China, the world's two biggest economies, to secure the supply chains of the key computing technology of the future, from semiconductors to AI software. China, in particular, has invested heavily in the connected car market, and inroads made by Chinese manufacturers in Europe have worried US officials.

In 2022 about 346,000 electric cars were reportedly sold in California. But the same year its greenhouse gas emissions dropped a whopping 9.3 million metric tons — the amount produced by 2.2 million gas-powered cars — lowering emissions 2.4% from the year before. "The biggest drop came from transportation, due largely to the increased use of renewable fuels," according to the state's Air Resources Board, touting a newly-released report. (And electricity sector emissions also fell by 2.6 million metric tons, or 4.1%, "even as electricity usage rose," according to The Hill — "a dichotomy that the regulators attributed to an increase in solar and wind power generation.") So despite a growing economy, "the latest data underscores a continued trend of steady emissions decline..." according to a statement from the Board. "Between 2000 to 2022, emissions fell by 20% while California's gross domestic product increased by 78%, pointing to the effectiveness of the state's climate change and air quality programs." And the amount of carbon dioxide equivalent emitted per unit of economic output ("carbon intensity") has also dropped 55% in the last 20 years: [In 2022] the electricity sector had its lowest carbon intensity since 2000. Wind and solar now represent 30% of generation and in-state solar increased by 15% from 2021, driven by requirements under the state's Cap-and-Trade Program and Renewables Portfolio Standard. Furthermore, California increased its battery storage by 757% from 2019 through 2023, bolstering its renewable energy efforts. The storage capacity is enough to power 6.6 million homes for up to four hours. Industrial emissions declined by 2%, also falling to the lowest level in 22 years. While refinery emissions remained essentially flat, emissions from oil and gas extraction declined, as did emissions from other fuel use, cement manufacturing, and cogeneration facilities. [The Hill says 2022's industrial emissions were 21.7% below year-2000 levels, according to the report.] Livestock emissions, which are responsible for 70% of agriculture's greenhouse gas emissions, peaked in 2012 and once again saw reductions in 2022. The decrease is driven by the use of methane digesters funded by the California Climate Investments and incentivized by the Low Carbon Fuel Standard, which capture emissions at the source and convert them to clean fuel. Landfill methane emissions also continued to decline in 2022. This decline can be attributed in part to the state's efforts to reduce disposal of organic waste, as well as the California Landfill Methane Regulation, which requires landfill operators to monitor and capture emissions escaping from their facilities. One local news site calls the drop in emissions "shocking," but adds that "the trend is expected to continue. In the second quarter of 2024, 118,181 zero-emission vehicles were purchased in the state, good for about one-quarter of all new car sales." California governor Gavin Newsom said his state "is proving that climate action goes hand-in-hand with economic growth. We've slashed carbon pollution by a whopping 20% since the turn of the century all while building the world's fifth largest economy. Cleaner air, more good jobs — that's the California way."

Nature published an introduction to running an LLM locally, starting with the example of a bioinformatician who's using AI to generate readable summaries for his database of immune-system protein structures. "But he doesn't use ChatGPT, or any other web-based LLM." He just runs the AI on his Mac... Two more recent trends have blossomed. First, organizations are making 'open weights' versions of LLMs, in which the weights and biases used to train a model are publicly available, so that users can download and run them locally, if they have the computing power. Second, technology firms are making scaled-down versions that can be run on consumer hardware — and that rival the performance of older, larger models. Researchers might use such tools to save money, protect the confidentiality of patients or corporations, or ensure reproducibility... As computers get faster and models become more efficient, people will increasingly have AIs running on their laptops or mobile devices for all but the most intensive needs. Scientists will finally have AI assistants at their fingertips — but the actual algorithms, not just remote access to them. The article's list of small open-weights models includes Meta's Llama, Google DeepMind's Gemma, Alibaba's Qwen, Apple's DCLM, Mistral's NeMo, and OLMo from the Allen Institute for AI. And then there's Microsoft: Although the California tech firm OpenAI hasn't open-weighted its current GPT models, its partner Microsoft in Redmond, Washington, has been on a spree, releasing the small language models Phi-1, Phi-1.5 and Phi-2 in 2023, then four versions of Phi-3 and three versions of Phi-3.5 this year. The Phi-3 and Phi-3.5 models have between 3.8 billion and 14 billion active parameters, and two models (Phi-3-vision and Phi-3.5-vision) handle images1. By some benchmarks, even the smallest Phi model outperforms OpenAI's GPT-3.5 Turbo from 2023, rumoured to have 20 billion parameters... Microsoft used LLMs to write millions of short stories and textbooks in which one thing builds on another. The result of training on this text, says Sébastien Bubeck, Microsoft's vice-president for generative AI, is a model that fits on a mobile phone but has the power of the initial 2022 version of ChatGPT. "If you are able to craft a data set that is very rich in those reasoning tokens, then the signal will be much richer," he says... Sharon Machlis, a former editor at the website InfoWorld, who lives in Framingham, Massachusetts, wrote a guide to using LLMs locally, covering a dozen options. The bioinformatician shares another benefit: you don't have to worry about the company updating their models (leading to different outputs). "In most of science, you want things that are reproducible. And it's always a worry if you're not in control of the reproducibility of what you're generating." And finally, the article reminds readers that "Researchers can build on these tools to create custom applications..." Whichever approach you choose, local LLMs should soon be good enough for most applications, says Stephen Hood, who heads open-source AI at the tech firm Mozilla in San Francisco. "The rate of progress on those over the past year has been astounding," he says. As for what those applications might be, that's for users to decide. "Don't be afraid to get your hands dirty," Zakka says. "You might be pleasantly surprised by the results."

First released on July 11th, the Firefox-based Zen browser is "taking a different approach to the user interface," according to the blog It's FOSS. The Register says the project "reminds us strongly of Arc, a radical Chromium-based web browser... to modernize the standard web browser UI by revising some fundamental assumptions." [Arc] removes the URL bar from front and center, gets rid of the simple flat list of tabs, and so on. Zen is trying to do some similar things, but in a slightly more moderate way — and it's doing it on the basis of Mozilla's Firefox codebase... Instead of the tired old horizontal tab bar you'll see in both Firefox and Chrome, Zen implements its own tab bar... By default, this tab bar is narrow and just shows page icons — but there are some extra controls at the bottom of the sidebar, one of which expands the sidebar to show page titles too. For us, it worked better than Vivaldi's fancier sidebar. The article concludes it's "a new effort to modernize web browsing by bringing tiling, workspaces, and so on — and it's blissfully free of Google code." One Reddit comment swooned over Zen's "extraordinary" implementation of a distraction-free "Compact Mode" (hiding things like the sidebar and top bar). And It's Foss described it as a "tranquil," browser, "written using CSS, C++, JavaScript, and a few other programming languages, with a community of over 30 people contributing to it." The layout of the interface felt quite clean to me; there were handy buttons on the top to control the webpage, manage extensions, and a menu with additional options... The split-view functionality allows you to open up two different tabs on the same screen, allowing for easy multitasking when working across different webpages... I split two tabs, but in my testing, I could split over 10+ tabs... If you have a larger monitor, then you are in for a treat... The Zen Sidebar feature... can run web apps alongside any open tabs. This can be helpful in situations where you need to quickly access a service like a note-taking app, Wikipedia, Telegram, and others. On the customization side of things, you will find that Zen Browser supports everything that Firefox does, be it the settings, adding new extensions/themes/plugins, etc. The Register points out it's easy to give it a try. "Being based on Firefox means that as well as running existing extensions, it can connect to Mozilla's Sync service and pick up not just your bookmarks, but also your tabs from other instances." And beyond all that, "There's just something satisfying about switching browsers every now and again..." argues the tech site Pocket-Lint: Zen Browser's vertical tabs layout is superb and feels much better than anything available in standard Firefox. [Firefox recently offered vertical tabs and a new sidebar experience in Nightly/Firefox Labs 131.] The tab bar can be set to automatically hide and show up whenever you hover near it, and it also contains quick access buttons to bookmarks, settings, and browsing history. The tab bar also contains a profile switcher... One of the greatest parts of the Zen Browser is the community that has popped up around it. At its heart, Zen Browser is a community-driven project... Zen Browser themes are aesthetic and functional tweaks to the UI. While there aren't a ton available right now, the ones that are show a lot of promise for the browser's future... I've personally gotten great use out of the Super URL Bar theme, which makes your URL bar expand and become the focus of your screen while typing in it... There's a lot you can do to make Zen Browser feel nearly exactly like what you want it to feel like. The "Business Standard calls it "an open-source alternative to Chromium-based browsers," adding "Where Zen truly shines is it offers a range of customisation, tab management, and workspace management..." Their theme store offers a range of options, including modifications to the bookmark toolbar, a floating URL bar, private mode theming, and removal of browser padding. In addition to these, users can also choose from custom colour schemes and built-in theming options... The Sidebar is another neat feature which allows you to open tabs in a smaller, smartphone-sized window. You can view websites in mobile layout by using this panel. It's "focused on being always at the latest version of Firefox," according to its official site, noting that Firefox is known for its security features. But then, "We also have additional security features like https only built into Zen Browser to help keep you safe online." And it also promises automated Releases "to ensure security." It's FOSS adds that you can get Zen Browser for Linux, Windows, and macOS from its official website (adding "They also offer it on the Flathub store for further accessibility on Linux.") And its source code is available on GitHub.

German law enforcement seized 47 cryptocurrency exchange services "that facilitated illegal money laundering activities for cybercriminals," according to BleepingComputer, "including ransomware gangs." Long-time Slashdot reader Arrogant-Bastard shares their report: The platforms allowed users to exchange cryptocurrencies without following applicable "Know Your Customer" regulations, meaning that users remained completely anonymous when making transactions. This created a low-risk environment for cybercriminals to launder their proceeds without fearing prosecution or being tracked. "Exchange services that enable such anonymous financial transactions and thus money laundering represent one of the most relevant building blocks in the criminal value chain of the cybercrime phenomenon," reads a Federal Criminal Police Office (BKA) announcement... When visiting any of the seized exchanges, you are now redirected to a warning page titled "Operation Final Exchange," which warns visitors that they have been deceived by the promises of anonymity by the operators of these platforms. The new site notes years-long promises from the exchanges "that their hosting cannot be found, that they do not store any customer data and that all data is deleted immediately after the transaction... "We have found their servers and seized them — development servers, production servers, backup servers. We have their data — and therefore we have your data. Transactions, registration data, IP addresses. "Our search for traces begins. See you soon."

The republic of Cyprus "has outstripped all other EU member states in embracing hot-water solar systems," reports the Guardian, "with an estimated 93.5 % of households exploiting the alternative energy form for domestic needs." EU figures show the eastern Mediterranean island exceeding renewable energy targets set in the heating and cooling of buildings thanks to the widespread use of the solar thermal technology... [First introduced in the late 1960s], the solar thermal systems not only collected solar energy as heat — usually generated through electricity and the burning of fossil fuels — they were extremely cost-effective and had helped spawn an entire industry [says Charalampos Theopemptou, the island's first environment commissioner and the head of the Cypriot parliament's environment committee]. "It's been great for low-income families and then there's the jobs: so many have been generated," the MP says. "There are the local manufacturers who produce the parts and then all the people who are trained to install them. It's big business." In his role as environment commissioner, Theopemptou pushed hard to make the solar systems obligatory on all newly constructed residential and commercial buildings... The popularity of the water heaters is such that a union of local solar thermal industrialists was established in 1977. Since then, more than 962,564 square cubic metres of "solar [panel] collectors" have been installed, the union says. Increasingly, the country's vibrant tourist industry has also resorted to the green solution with solar-powered hot water systems deployed in, they say, close to 100% of hotels... For Demetra Asprou, a retired engineer, it's obvious that a region blessed with more than 300 days of sunshine a year should embrace solar energy. "It reduces electricity costs, increases the efficiency with which hot water is provided and is kind to the environment," she says. "Why would anyone use other, more traditional means to heat up water when only a few hours of sunlight, between 11am and 2pm, is enough for a 200-litre [44-gallon] tank to be filled with warm water that will last 48 hours? On days when there is no sunlight, which is rare, you always have electricity as a backup if necessary... Installation costs may be three times higher today, but there are EU-funded grants that the government hands out and within a year it's all paid off," she says. "After that, you basically have free hot water and see your electricity bills greatly reduced. In a country like Cyprus, it's a no-brainer."

"Many GitHub users this week received a novel phishing email warning of critical security holes in their code," reports Krebs on Security — citing an email shared by one of his readers: "Hey there! We have detected a security vulnerability in your repository. Please contact us at https://github-scanner[.]com to get more information on how to fix this issue...." Clicking the "I'm not a robot" button generates a pop-up message asking the user to take three sequential steps to prove their humanity. Step 1 involves simultaneously pressing the keyboard key with the Windows icon and the letter "R," which opens a Windows "Run" prompt that will execute any specified program that is already installed on the system. Step 2 asks the user to press the "CTRL" key and the letter "V" at the same time, which pastes malicious code from the site's virtual clipboard. Step 3 — pressing the "Enter" key — causes Windows to launch a PowerShell command, and then fetch and execute a malicious file from github-scanner[.]com called "l6e.exe...." According to an analysis at the malware scanning service Virustotal.com, the malicious file downloaded by the pasted text is called Lumma Stealer, and it's designed to snarf any credentials stored on the victim's PC. Even though this might fool some users, Krebs points out that Microsoft "strongly advises against nixing PowerShell because some core system processes and tasks may not function properly without it. What's more, doing so requires tinkering with sensitive settings in the Windows registry..." Thanks to long-time Slashdot reader sinij for sharing the article.

In the antitrust trial alleging Google had an ad-selling monopoly, "government lawyers have said some of their strongest evidence is in Google's own internal communications," reports the Wall Street Journal: [In 2010] a new crop of ad-tech companies were threatening Google's bottom line. "One way to make sure we don't get further behind in the market is picking up the one with the most traction and parking it somewhere..." [wrote YouTube Chief Executive Neal Mohan, who previously ran Google's display-ads business]. Google ended up buying one such company, AdMeld, for $400 million in 2011. Google shut down AdMeld two years later, after incorporating some of the startup's technology into its ad exchange, known commonly as AdX. The Justice Department argued that AdMeld was part of a larger trend: Google acquiring nascent rivals to corner the market and then locking customers into using its products by conditioning access to one software tool on them paying for another... In a 2016 email introduced by the government, Google executive Jonathan Bellack asked colleagues: "Is there a deeper issue with us owning the platform, the exchange, and a huge network? The analogy would be if Goldman or Citibank owned the NYSE [New York Stock Exchange]...." The Justice Department also cited a 2018 email from another then-executive, Chris LaSala, who raised concerns internally over the 20% cut that Google takes from many of its AdX customers, saying Google was extracting "irrationally high rent" from users. "I don't think there is 20% of value in comparing two bids," wrote LaSala. "AdX is not providing additional liquidity to the market. It is simply running the auction." Another former Google executive, Eisar Lipkovitz, testified that Google's omnipresence in ad-tech gives rise to conflicts of interest. Lipkovitz was rebuffed when he tried to get Google to lower the cut it took from AdX, he testified in a prerecorded deposition. The Justice Department finished presenting its case on Friday. Other witnesses included Google customers. One was Stephanie Layser, a former News Corp executive, who said she felt she had no choice but to use Google technology because the search giant has such market power that switching to another ad server would have meant losing out on millions in advertising revenue. Google's lawyer countered that "There will be no witness in this case who can say with clarity where this industry is going in the next five years." Or, as the Wall Street Journal puts it, "It makes no sense to focus on display ads, Google argues, when the industry is shifting to apps, social media and streaming services. Far from monopolizing the space, Google is actually losing ground, Google lawyer Karen Dunn said in her opening trial statement..."

Salon looks closer at a new $51,744-per-violation AI regulation officially approved one month ago by America's FTC — calling it a financial blow "If you're a digital media company whose revenue comes from publishing AI-generated articles and fake product reviews. But they point out the rules also ban "product review suppression." Per the ruling, that means it's a violation for "anyone to use an unfounded or groundless legal threat, a physical threat, intimidation, or a public false accusation in response to a consumer review... to (1) prevent a review or any portion thereof from being written or created, or (2) cause a review or any portion thereof to be removed, whether or not that review or a portion thereof is replaced with other content." Finally... The rule makes it a violation for a business to "provide compensation or other incentives in exchange for, or conditioned expressly or by implication on, the writing or creation of consumer reviews expressing a particular sentiment, whether positive or negative, regarding the product, service or business...." [T]he new rule also prevents secretly advertising for yourself while pretending to be an independent outlet or company. It bars "the creation or operation of websites, organizations or entities that purportedly provide independent reviews or opinions of products or services but are, in fact, created and controlled by the companies offering the products or services." In an earlier statement, FTC Consumer Protection Bureau head Sam Levine, said the new rule "should help level the playing field for honest companies. We're using all available means to attack deceptive advertising in the digital age," he said. Thanks to long-time Slashdot reader mspohr for sharing the article.

An anonymous reader shared this story from SFGate: A boy who was kidnapped from an Oakland playground in 1951 has been found alive on the East Coast, a remarkable resolution to a mystery that has haunted his family for over half a century. On February 21, 1951, 6-year-old Luis Armando Albino was playing with his older brother Roger at Jefferson Square Park. The boys had recently immigrated with their mother and four other siblings from Puerto Rico... That afternoon, Luis and 10-year-old Roger walked down the block from their home at 730 Brush Street to play in the park. They were approached by a woman in her 30s, wearing a green bandana over her hair, who began chatting with Luis in Spanish. She promised she would buy him candy if he came along with her, and little Luis agreed to join her. Wary, Roger trailed the pair for a while before returning home to alert an adult to the strange encounter. Oakland police were called by frantic family members and a search was immediately launched... Antonia [the boy's mother] was convinced her son was alive. "She came once a week, then once a month, then at least once a year, to see the shake of the head, to have the answer 'no' translated for her although she could read it in the officers' faces," the Oakland Tribune wrote in 1966... Decades passed. In 2020, Luis' niece, Alida Alequin, took a DNA test on a whim, the Mercury News reported. The service returned several possible family members to the Oakland woman. One of them was a man who Alequin had never met. After some internet sleuthing, she began to suspect this man might be the missing uncle she'd heard so much about. She reached out to the man but didn't hear back. Earlier this year, Alequin tried again. Armed with photos, she took her evidence to the Oakland Police Department's missing persons unit. In short order, the FBI and California Department of Justice were also investigating Alequin's lead. They discovered the man was living on the East Coast, had worked as a firefighter and served two tours in Vietnam with the Marine Corps. This week, the Mercury News first reported that a DNA test confirmed what Alequin suspected: This was Luis Albino. In June, Luis flew to California to reunite with his family, among them his devoted brother Roger... For over 70 years, he lived on the East Coast believing he was the son of another couple.... When Luis met Alequin for the first time this summer, he held her in an embrace. "Thank you," he said, "for finding me."

The JavaScript runtime Bun is a Node.js/Deno alternative (that's also a bundler/test runner/package manager). And Bun 1.1.28 now includes experimental support for ">compiling and running native C from JavaScript, according to this report from The New Stack: "From compression to cryptography to networking to the web browser you're reading this on, the world runs on C," wrote Jarred Sumner, creator of Bun. "If it's not written in C, it speaks the C ABI (C++, Rust, Zig, etc.) and is available as a C library. C and the C ABI are the past, present, and future of systems programming." This is a low-boilerplate way to use C libraries and system libraries from JavaScript, he said, adding that this feature allows the same project that runs JavaScript to also run C without a separate build step... "It's good for glue code that binds C or C-like libraries to JavaScript. Sometimes, you want to use a C library or system API from JavaScript, and that library was never meant to be used from JavaScript," Sumner added. It's currently possible to achieve this by compiling to WebAssembly or writing a N-API (napi) addon or V8 C++ API library addon, the team explained. But both are suboptimal... WebAssembly can do this but its isolated memory model comes with serious tradeoffs, the team wrote, including an inability to make system calls and a requirement to clone everything. "Modern processors support about 280 TB of addressable memory (48 bits). WebAssembly is 32-bit and can only access its own memory," Sumner wrote. "That means by default, passing strings and binary data JavaScript WebAssembly must clone every time. For many projects, this negates any performance gain from leveraging WebAssembly." The latest version of Bun, released Friday, builds on this by adding N-API (nap) support to cc [Bun's C compiler, which uses TinyCC to compile the C code]. "This makes it easier to return JavaScript strings, objects, arrays and other non-primitive values from C code," wrote Sumner. "You can continue to use types like int, float, double to send & receive primitive values from C code, but now you can also use N-API types! Also, this works when using dlopen to load shared libraries with bun:ffi (such as Rust or C++ libraries with C ABI exports).... "TinyCC compiles to decently performant C, but it won't do advanced optimizations that Clang or GCC does like autovectorization or very specialized CPU instructions," Sumner wrote. "You probably won't get much of a performance gain from micro-optimizing small parts of your codebase through C, but happy to be proven wrong!"

The Washington Post reports that electric vehicles made by General Motors now can use Tesla's Superchargers. (GM's charger adapters "will first be made available to customers in the United States, followed by availability for Canadian customers later this year.") The Post writes that the move "expands the number of vehicles compatible with the North American Charging Standard developed by Tesla" — and also marks "another step forward for efforts to settle on a universal public charger network for battery-powered cars and trucks in the U.S. "It could also allay some GM customers' concerns about a lack of charging options." The new changes take effect immediately, along with sales of the GM-approved power adapters... The deal makes roughly 17,800 Tesla Superchargers available to drivers of GM-manufactured vehicles such as the Chevy Bolt, Cadillac Lyriq and Silverado EV, with the help of an adapter that costs $225... GM estimates that the partnership with Tesla contributes to an overall network of 231,800 fast chargers across the United States available to drivers of its vehicles. GM is also part of IONNA, a joint venture of eight automakers that plans to build at least 30,000 high-powered chargers nationwide. GM's statement calls it "a move that will help accelerate fast and convenient charging options for current and future EV drivers." And the move comes 15 months after GM announced it was adopting the standard — a move followed within weeks by similar announcements from Rivian, Ford, Volvo, Nissan, Hyundai and Kia. "Ford and Rivian have started distributing adapters for their EVs," the Washington Post points out, "while others, such as BMW, Honda, Hyundai and Mercedes-Benz have promised to start making their vehicles compatible this year or next." "Knowing we will now have access to Tesla Supercharger locations means that range anxiety has now virtually evaporated..." argues a Chevy owner at CleanTechnica: This is mostly good news for drivers of electric cars from GM. Tesla and The General have been bitter enemies in the past, with GM opposing Tesla's direct sales model in many states. The once fierce battle has cooled in recent years, but GM essentially won by keeping Tesla from selling direct to the public in several US states, including its new home of Texas. Nevertheless, the two companies are now cooperating, which is a bonus for drivers... Despite some niggling concerns, this is a big deal for EV drivers in North America. Tesla Superchargers are the gold standard in the industry today. There are fast, reliable, and always located in clean, well-lit places where restrooms and fresh foods are available. This could very well change the conversation about electric cars to the point where by the time GM, Ford, and Stellantis get their plug-in hybrids into showrooms, the demand for them will have shrunk considerably. One GM executive says in this week's statement that "GM's ongoing efforts to help accelerate the expansion of public charging infrastructure is an integral part of our commitment to an all-electric future."

Polypropylene and polyethylene plastics "can be recycled," reports Ars Technica. But as "polyolefin" polymers, "the process can be difficult and often produces large quantities of the greenhouse gas methane. "Now, researchers at the University of California, Berkeley have come up with a method of recycling these polymers that uses catalysts that easily break their bonds, converting them into propylene and isobutylene, which are gasses at room temperature. Those gasses can then be recycled into new plastics..." [T]he previous catalysts were expensive metals that did not remain pure long enough to convert all of the plastic into gas. Using sodium on alumina followed by tungsten oxide on silica proved much more economical and effective, even though the high temperatures required for the reaction added a bit to the cost. In both plastics, exposure to sodium on alumina broke each polymer chain into shorter polymer chains and created breakable carbon-carbon double bonds at the ends. The chains continued to break over and over. Both then underwent a second process known as olefin metathesis. They were exposed to a stream of ethylene gas flowing into a reaction chamber while being introduced to tungsten oxide on silica, which resulted in the breakage of the carbon-carbon bonds. The reaction breaks all the carbon-carbon bonds in polyethylene and polypropylene, with the carbon atoms released during the breaking of these bonds ending up attached to molecules of ethylene... The entire chain is catalyzed until polyethylene is fully converted to propylene, and polypropylene is converted to a mixture of propylene and isobutylene. This method has high selectivity — meaning it produces a large amount of the desired product. That means propylene derived from polyethylene, and both propylene and isobutylene derived from polypropylene. Both of these chemicals are in high demand, since propylene is an important raw material for the chemical industry, while isobutylene is a frequently used monomer in many different polymers, including synthetic rubber and a gasoline additive. "Because plastics are often mixed at recycling centers, the researchers wanted to see what would happen if polypropylene and polyethylene underwent isomerizing ethenolysis together," the article adds. "The reaction was successful, converting the mixture into propylene and isobutylene, with slightly more propylene than isobutylene." The reaction worked, even if there were contaminants from other plastics. And "When the research team increased the scale of the experiment, it produced the same yield, which looks promising for the future...." The researchers hope this some day could reduce the demand for chemicals derived from fossil fuels. Thanks to Slashdot reader echo123 for sharing the article.

"In all likelihood, in the next 25 years, we'll find evidence of life on another planet..." begins a new essay by author Dave Eggers in the Washington Post. "In more than a dozen conversations with some of the best minds in astrophysics, I did not meet anyone who was doubtful about finding evidence of life elsewhere — most likely on an exoplanet beyond our solar system. It was not a matter of if. It was a matter of when." [A]ll evidence points to us getting closer, every year, to identifying moons in our solar system, or exoplanets beyond it, that can sustain life. And if we don't find conditions for life on the moons near us, we'll find it on exoplanets — that is, planets outside our solar system. Within the next few decades, we'll likely find an exoplanet that has an atmosphere, that has water, that has carbon and methane and oxygen. Or some combination of those things. And thus, the conditions for life. In a few years, NASA will launch the Nancy Grace Roman Space Telescope, which will have a panoramic field of vision a hundred times greater than the Hubble Space Telescope. And on the Nancy Grace Roman Space Telescope — we'll call it Roman from here on out — there will be a coronagraph, a device designed to perform something called, beautifully, starlight suppression. Starlight suppression is the blocking of the rays of a faraway star so that we can see behind it and around it. Once we can master starlight suppression, with Roman and NASA's next astrophysics flagship, the Habitable Worlds Observatory, we'll find the planets where life might exist. To recap: For thousands of years, humans have wondered whether life is possible elsewhere in the universe, and now we're within striking distance of being able to say not only yes, but here. And yet this is not front-page news. I didn't really know how close we were to this milestone until I visited the Jet Propulsion Laboratory in Pasadena, Calif., on a hot and dry day in June... Eggers' article is part of an ongoing series called "Who is government?" (For the series Michael Lewis also profiled the uncelebrated number-crunchers at the U.S. Department of Labor, while Casey Cep wrote about the use of DNA to identify the remains of World War II soldiers for America's Veteran Affairs' department's.) But this week Eggers wrote that the work being done at NASA's Jet Propulsion Laboratory "is the most inspiring research and exploration being done by any humans on our planet..." "No billionaires will fund work like this because there's no money in it. This is government-funded research to determine how the universe was created and whether we are alone in it. If NASA and JPL were not doing it, it would not be done." Eggers emphasizes later that "doesn't mean it's intelligent life, or even semi-intelligent life. It could be bacteria, or some kind of interstellar sea cucumber. But whatever form it takes, we are close to finding it..."

The administrators of Great Britain's power grid admit that it's often unable to use energy-storage batteries due to old computer systems and an old network with "not enough cables", according to the Financial Times — though the system operator says they're making progress after upgrading their system last December: The company has plans to lower the rate at which batteries are sidelined to single figures by early next year [said Craig Dyke, from National Grid's electricity system operator], calling current levels "higher than where we want them to be". Dyke's comments came in response to a letter from four leading battery storage groups which said National Grid's "electricity system operator" or ESO division was making the country's power costlier and dirtier by failing to use their technology properly. "Consumers are paying more, clean renewable energy is being wasted, and fossil fuel generation is being used instead," they said... depriving them of revenue and undermining investor confidence. While the U.K. has the world's second-largest offshore wind market, the article notes that when the system operator can't send its power where it's needed, "the ESO pays wind farms in one place to switch off... and can also need to pay gas-fired power plants in another area to turn on. These payments add up to hundreds of millions of pounds each year, and the costs are passed on to household and business energy bills." "Use of battery storage abroad has soared in places such as California, where batteries soak up solar power during the day and regularly supply a fifth of the state's power in the evening..."

"The cab was cut from a 1997 Jeep Grand Cherokee," writes the New York Times. "The engine once revved up a 1985 Toyota Celica; and 107 hand-sewn rubber segments, courtesy of Mr. Tymofichuk's wife, help to direct low-pressure air beneath the craft so that it rises eight inches above the ground..." On a cold spring day in a small garage in Alberta, Canada, an engine revved up and an improbable machine — fabricated from auto parts, a hand-sewn rubber skirt and an abandoned fiberglass hull — came to life. A homemade hovercraft began to rise off the ground with a small crew standing by. The successful liftoff was the culmination of a lifelong fascination of Robert Tymofichuk, 55, who spent about 1,800 hours over a year working on it [according to this nifty video on YouTube ]. And, to the gratitude of passengers, it comes with heated seats. "If you're going through all that hassle, you might as well make yourself comfortable," Mr. Tymofichuk said. He repurposed the seats from a Volkswagen, so the heating coils were already installed. Achieve speeds around 40 miles per hour (or 64 kmph), "Mr. Tymofichuk's hovercraft now sails above land and water, a bright red gem coasting over the Saskatchewan River," according to the article. And it also quotes Mr. Tymofichuk as saying it's the fulfillment of a childhood dream. "To actually have something constructed with your own hands be zipping around, and it's fully functional — it's like magic."

"Exceed the speed limit in one of the 27 European Union countries, and you may get some pushback from your vehicle," reports Car and Driver. "As of July, new cars sold in the EU must include a speed-warning device that alerts drivers if they exceed the posted limit." The warnings can be ither acoustic or haptic, "though the European Commission gives automakers the latitude to supplant those passive measures with either an active accelerator pedal that applies counterpressure against the driver's foot or a governor that restricts the vehicle's speed to the legal limit." Drivers can override or deactivate these admonishments, but the devices must default to their active state at startup. Now California is looking to emulate the EU with legislation that would mandate in-car speed-warning devices [for driving more than 10 miles per hour over the speed limit — in "just about every 2030 model-year vehicle equipped with either GPS or a front-facing camera"]. The article cites statistics that 18% of those drivers involved in fatal crashes were speeding. Although the projects director at the European Transport Safety Council also acknowledges the systems may struggle to identify speed limits from passing signs — and that their testing shows the systems generally irritate drivers, who often deactivate the systems...

Friday America's Federal Trade Commission brought action against three companies for "anticompetitive and unfair" practices "that have artificially inflated the list price of insulin." For years, many of the millions of Americans who need insulin to survive "have been forced to pay exorbitant prices for a product that's inexpensive to make," writes NPR. "Now, the federal government is targeting one part of the system behind high insulin prices." While out-of-pocket costs have gone down for many people to $35 a month, questions remain on how the drug became so expensive in the first place. In a new lawsuit filed Friday, the Federal Trade Commission said it's going after one link in the chain: pharmacy benefit managers. The FTC brought action against the top pharmacy benefit managers (PBMs) — CVS Health's Caremark Rx, Cigna's Express Scripts, and United Health Group's OptumRx — saying the companies created a "perverse drug rebate system" that artificially inflates the cost of insulin. If the suit is successful, it could further drive down costs for patients at the pharmacy counter. PBMs are essentially the middlemen between drug manufacturers and insurance providers. Their job is to reduce drug prices. But the process is complex and opaque, and critics say they're actually driving prices up for patients. The FTC said a big issue is that PBMs' revenue is tied to rebates and fees — which are based on a percentage of a drug's list price. Essentially, in the case of insulin, when the drug costed more, it generated higher rebates and fees for PBMs. "Even when lower list price insulins became available that could have been more affordable for vulnerable patients, the PBMs systemically excluded them in favor of high list price, highly rebated insulin products," the FTC said in a press release on Friday. The three PBMs named in the FTC lawsuit make up about 80% of the market. According to the suit, the PBMs collected billions of dollars in rebates and fees while insulin became increasingly unaffordable. Over the last two decades, the cost of the lifesaving drug shot up 600% — forcing many Americans with diabetes to ration their medication and jeopardize their health. In 2019, one 1 of 4 insulin patients was unable to afford their medication, according to the FTC. Some people have died. The FTC's statement says the companies "have abused their economic power by rigging pharmaceutical supply chain competition in their favor, forcing patients to pay more for life-saving medication... While PBM respondents collected billions in rebates and associated fees according to the complaint, by 2019 one out of every four insulin patients was unable to afford their medication..." "[A]ll drug manufacturers should be on notice that their participation in the type of conduct challenged here raises serious concerns, and that the Bureau of Competition may recommend suing drug manufacturers in any future enforcement actions."
