Longtime Slashdot reader schwit1 shares a report from Ars Technica: Every other week, it seems, a new Chinese launch company pops up with a rocket design and a plan to reach orbit within a few years. For a long time, the majority of these companies revealed designs that looked a lot like SpaceX's Falcon 9 rocket. The first of these copy cats, the medium-lift Zhuque-3 rocket built by LandSpace, launched earlier this month. Its primary mission was nominal, but the Zhuque-3 rocket failed its landing attempt, which is understandable for a first flight. Doubtless there will be more Chinese Falcon 9-like rockets making their debut in the near future. However, over the last year, there has been a distinct change in announcements from China when it comes to new launch technology. Just as SpaceX is seeking to transition from its workhorse Falcon 9 rocket -- which has now been flying for a decade and a half -- to the fully reusable Starship design, so too are Chinese companies modifying their visions.

The trend began with the Chinese government. In November 2024 the government announced a significant shift in the design of its super-heavy lift rocket, the Long March 9. Instead of the previous design, a fully expendable rocket with three stages and solid rocket boosters strapped to the sides, the country's state-owned rocket maker revealed a vehicle that mimicked SpaceX's fully reusable Starship. Around the same time, a Chinese launch firm named Cosmoleap announced plans to develop a fully reusable "Leap" rocket within the next few years. An animated video that accompanied the funding announcement indicated that the company seeks to emulate the tower catch-with-chopsticks methodology that SpaceX has successfully employed.

But wait, there's more. In June a company called Astronstone said it too was developing a stainless steel, methane-fueled rocket that would also use a chopstick-style system for first stage recovery. Astronstone didn't even pretend to not copy SpaceX, saying it was "fully aligning its technical approach with Elon Musk's SpaceX." And then, on Friday, the state-aligned China.com reported that a company called "Beijing Leading Rocket Technology" took things a step further. It has named its vehicle "Starship-1," adding that the new rocket will have enhancements from AI and is billed as a "fully reusable AI rocket."

Adobe is integrating Photoshop, Express, and Acrobat directly into ChatGPT so users can edit photos, design graphics, and tweak PDFs through the chatbot. The Verge reports: The Adobe apps are free to use, and can be activated by typing the name of the app alongside an uploaded file and conversational instruction, such as "Adobe Photoshop, help me blur the background of this image." ChatGPT users won't have to specify the name of the app again during the same conversation to make additional changes. Depending on the instructions, Adobe's apps may offer a selection of results to choose from, or provide a UI element that the user can manually control -- such as Photoshop sliders for adjusting contrast and brightness.

The ChatGPT apps don't provide the full functionality of Adobe's desktop software. Adobe says the Photoshop app can edit specific sections of images, apply creative effects, and adjust image settings like brightness, contrast and exposure. Acrobat in ChatGPT can edit existing PDFs, compress and convert other documents into a PDF format, extract text or tables, and merge multiple files together.

The Adobe Express app allows ChatGPT users to both generate and edit designs, such as posters, invitations, and social media graphics. Everything in the design can be edited without leaving ChatGPT, from replacing text or images, to altering colors and animating specific sections. If ChatGPT users do want more granular control over a project they started in the chatbot, those photos, PDFs, and designs can be opened directly in Adobe's native apps to pick up where they left off.

Google said it's working to create two different categories of artificial intelligence-powered smart glasses to compete next year with existing models from Meta Platforms: one with screens, and another that's audio focused. From a report: The first AI glasses that Google is collaborating on will arrive sometime in 2026, it said in a blog post Monday. Samsung Electronics, Warby Parker and Gentle Monster are among its early hardware partners, but the companies have yet to show any final designs. Google also outlined several software improvements coming to Samsung's Galaxy XR headset, including a travel mode that will allow the mixed-reality device to be used in cars and on planes.

Nuclear engineer Lonnie Johnson worked on NASA's Galileo mission, has more than 140 patents, and invented the Super Soaker water gun. But now he's working on "a potential key to unlock a huge power source that's rarely utilized today," reports the Atlanta Journal-Constitution. [Alternate URL here.]

Waste heat... The Johnson Thermo-Electrochemical Converter, or JTEC, has few moving parts, no combustion and no exhaust. All the work to generate electricity is done by hydrogen, the most abundant element in the universe. Inside the device, pressurized hydrogen gas is separated by a thin, filmlike membrane, with low pressure gas on one side and high pressure gas on the other. The difference in pressure in this "stack" is what drives the hydrogen to compress and expand, creating electricity as it circulates. And unlike a fuel cell, it does not need to be refueled with more hydrogen. All that's needed to keep the process going and electricity flowing is a heat source.

As it turns out, there are enormous amounts of energy vented or otherwise lost from industrial facilities like power plants, factories, breweries and more. Between 20% and 50% of all energy used for industrial processes is dumped into the atmosphere and lost as waste heat, according to the U.S. Department of Energy. The JTEC works with high temperatures, but the device's ability to generate electricity efficiently from low-grade heat sources is what company executives are most excited about. Inside JTEC's headquarters, engineers show off a demonstration unit that can power lights and a sound system with water that's roughly 200 degrees Fahrenheit — below the boiling point and barely warm enough to brew a cup of tea, said Julian Bell, JTEC's vice president of engineering. Comas Haynes, a research engineer at the Georgia Tech Research Institute specializing in thermal and hydrogen system designs, agrees the company could "hit a sweet spot" if it can capitalize on lower temperature heat...

For Johnson, the potential application he's most excited about lies beneath our feet. Geothermal energy exists naturally in rocks and water beneath the Earth's surface at various depths. Tapping into that resource through abandoned oil and gas wells — a well-known access point for underground heat — offers another opportunity. "You don't need batteries and you can draw power when you need it from just about anywhere," Johnson said. Right now, the company is building its first commercial JTEC unit, which is set to be deployed early next year. Mike McQuary, JTEC's CEO and the former president of the pioneering internet service provider MindSpring, said he couldn't reveal the customer, but said it's a "major Southeast utility company." "Crossing that bridge where you have commercial customers that believe in it and will pay for it is important," McQuary said...

On top of some initial seed money, the company brought in $30 million in a Series A funding in 2022 — money that allowed the company to move to its Lee + White headquarters and hire more than 30 engineers. McQuary said it expects to begin another round of fundraising soon.
"Johnson, meanwhile, hasn't stopped working on new inventions," the article points out. "He continues to refine the design for his solid-state battery..."

A severe spike in global DRAM prices has pushed Samsung Semiconductor to refuse a long-term RAM order from its own sibling, Samsung Electronics. The move is forcing the smartphone division into short, expensive renegotiations, which will likely mean higher costs for consumer devices. PCWorld reports: Samsung subsidiaries are, naturally, going to look to Samsung Semiconductor first when they need parts. Such was reportedly the case for Samsung Electronics, in search of memory supplies for its newest smartphones as the company ramps up production for 2026 flagship designs. But with so much RAM hardware going into new "AI" data centers -- and those companies willing to pay top dollar for their hardware -- memory manufacturers like Samsung, SK Hynix, and Micron are prioritizing data center suppliers to maximize profits.

The end result, according to a report from SE Daily spotted by SamMobile, is that Samsung Semiconductor rejected the original order for smartphone DRAM chips from Samsung Electronics' Mobile Experience division. The smartphone manufacturing arm of the company had hoped to nail down pricing and supply for another year. But reports say that due to "chipflation," the phone-making division must renegotiate quarterly, with a long-term supply deal rejected by its corporate sibling. A short-term deal, with higher prices, was reportedly hammered out.

Slashdot readers jmurtari and schwit1 shares news that a Russian astronaut slated for the next Dragon mission to the ISS has been removed after being caught photographing proprietary SpaceX hardware. UNITED24 reports: Russian cosmonaut Oleg Artemyev has been removed from the prime crew of SpaceX's Crew-12 mission to the International Space Station and replaced by fellow Roscosmos cosmonaut Andrey Fedyaev after sources alleged he photographed confidential SpaceX materials in California in violation of U.S. export control rules, according to The Insider on December 2. The outlet reported that Trishkin also said NASA did not want the controversy around Artemyev to become public, while Artemyev was removed from training at SpaceX's Hawthorne California, facility last week after allegedly photographing SpaceX engines and other internal materials on his phone and taking them off-site.

An anonymous reader shared this report from The Conversation: To make interplanetary travel faster, safer, and more efficient, scientists need breakthroughs in propulsion technology. Artificial intelligence is one type of technology that has begun to provide some of these necessary breakthroughs. We're a team of engineers and graduate students who are studying how AI in general, and a subset of AI called machine learning in particular, can transform spacecraft propulsion. From optimizing nuclear thermal engines to managing complex plasma confinement in fusion systems, AI is reshaping propulsion design and operations. It is quickly becoming an indispensable partner in humankind's journey to the stars...

Early nuclear thermal propulsion designs from the 1960s, such as those in NASA's NERVA program, used solid uranium fuel molded into prism-shaped blocks. Since then, engineers have explored alternative configurations — from beds of ceramic pebbles to grooved rings with intricate channels... [T]he more efficiently a reactor can transfer heat from the fuel to the hydrogen, the more thrust it generates. This area is where reinforcement learning has proved to be essential. Optimizing the geometry and heat flow between fuel and propellant is a complex problem, involving countless variables — from the material properties to the amount of hydrogen that flows across the reactor at any given moment. Reinforcement learning can analyze these design variations and identify configurations that maximize heat transfer.

Adobe is buying Semrush for $1.9 billion in a move to supercharge its AI-driven marketing stack. Reuters reports: Semrush designs and develops AI software that helps companies with search engine optimization, social media and digital advertising. The acquisition, expected to close in the first half of next year, would allow Adobe to help marketers better understand how their brands are viewed by online consumers through searches on websites and generative AI bots such as ChatGPT and Gemini. "The price is steep as Semrush isn't a massive revenue engine on its own, so Adobe is likely paying for strategic value. The payoff could be high too if Adobe can quickly turn Semrush's data into monetizable AI products," said Emarketer analyst Grace Harmon.

"While we are positive on Adobe restarting its M&A engine given the success that it has seen with this motion over the years... this deal likely does little to answer the questions revolving around the company's creative cloud business," added William Blair analysts.

Amazon announced that its satellite broadband project called Project Kuiper will now be known as Amazon Leo. GeekWire reports: Leo is a nod to "low Earth orbit," where Amazon has so far launched more than 150 satellites as part of a constellation that will eventually include more than 3,200. In a blog post, Amazon said the 7-year-old Project Kuiper began "with a handful of engineers and a few designs on paper" and like most early Amazon projects "the program needed a code name." The team was inspired by the Kuiper Belt, a ring of asteroids in the outer solar system.

A new website for Amazon Leo proclaims "a new era of internet is coming," as Amazon says its satellites can help serve "billions of people on the planet who lack high-speed internet access, and millions of businesses, governments, and other organizations operating in places without reliable connectivity." Amazon said it will begin rolling out service once it's added more coverage and capacity to the network. Details about pricing and availability haven't been announced.

Should we leave space exploration to robots — or prioritize human spaceflight, making us a multiplanetary species?

Harvard professor Robin Wordsworth, who's researched the evolution and habitability of terrestrial-type planets, shares his thoughts: In space, as on Earth, industrial structures degrade with time, and a truly sustainable life support system must have the capability to rebuild and recycle them. We've only partially solved this problem on Earth, which is why industrial civilization is currently causing serious environmental damage. There are no inherent physical limitations to life in the solar system beyond Earth — both elemental building blocks and energy from the sun are abundant — but technological society, which developed as an outgrowth of the biosphere, cannot yet exist independently of it. The challenge of building and maintaining robust life-support systems for humans beyond Earth is a key reason why a machine-dominated approach to space exploration is so appealing...

However, it's notable that machines in space have not yet accomplished a basic task that biology performs continuously on Earth: acquiring raw materials and utilizing them for self-repair and growth. To many, this critical distinction is what separates living from non-living systems... The most advanced designs for self-assembling robots today begin with small subcomponents that must be manufactured separately beforehand. Overall, industrial technology remains Earth-centric in many important ways. Supply chains for electronic components are long and complex, and many raw materials are hard to source off-world... If we view the future expansion of life into space in a similar way as the emergence of complex life on land in the Paleozoic era, we can predict that new forms will emerge, shaped by their changed environment, while many historical characteristics will be preserved. For machine technology in the near term, evolution in a more life-like direction seems likely, with greater focus on regenerative parts and recycling, as well as increasingly sophisticated self-assembly capabilities. The inherent cost of transporting material out of Earth's gravity well will provide a particularly strong incentive for this to happen.

If building space habitats is hard and machine technology is gradually developing more life-like capabilities, does this mean we humans might as well remain Earth-bound forever? This feels hard to accept because exploration is an intrinsic part of the human spirit... To me, the eventual extension of the entire biosphere beyond Earth, rather than either just robots or humans surrounded by mechanical life-support systems, seems like the most interesting and inspiring future possibility. Initially, this could take the form of enclosed habitats capable of supporting closed-loop ecosystems, on the moon, Mars or water-rich asteroids, in the mold of Biosphere 2. Habitats would be manufactured industrially or grown organically from locally available materials. Over time, technological advances and adaptation, whether natural or guided, would allow the spread of life to an increasingly wide range of locations in the solar system.
The article ponders the benefits (and the history) of both approaches — with some fasincating insights along the way.

"If genuine alien life is out there somewhere, we'll have a much better chance of comprehending it once we have direct experience of sustaining life beyond our home planet."

Slashdot reader joshuark shares this report from SFGate: The mystery object that struck a plane at 36,000 feet is likely not space debris, as some speculated, but rather a Silicon Valley test project gone wrong...

WindBorne Systems, a Palo Alto startup that uses atmospheric balloons to collect weather data for AI-based forecast models,has come forward to say that they believe they may be responsible for the object that hit the windshield... "At 6am PT, we sent our preliminary investigation to both NTSB and FAA, and are working with both of them to investigate further," [WindBorne's CEO John Dean posted on social media...] WindBorne said the company has launched more than 4,000 balloons and that it coordinates with the Federal Aviation Administration for every launch.
WindBorne "has conducted more than 4,000 launches," the company said in a statement, noting that they've always coordinated those launched with America's Federal Aviation Administration and filed aviation alerts for every launched balloon. Plus "The system is designed to be safe in the event of a midair collision... Our balloon is 2.4 pounds at launch and gets lighter throughout flight." We are working closely with the FAA on this matter. We immediately rolled out changes to minimize time spent between 30,000 and 40,000 feet. These changes are already live with immediate effect. Additionally, we are further accelerating our plans to use live flight data to autonomously avoid planes, even if the planes are at a non-standard altitude. We are also actively working on new hardware designs to further reduce impact force magnitude and concentration.

"Clippy, the animated paper clip that annoyed Microsoft Office users nearly three decades ago, might have just been ahead of its time," writes the Associated Press: Microsoft introduced a new artificial intelligence character called Mico (pronounced MEE'koh) on Thursday, a floating cartoon face shaped like a blob or flame that will embody the software giant's Copilot virtual assistant and marks the latest attempt by tech companies to imbue their AI chatbots with more of a personality... "When you talk about something sad, you can see Mico's face change. You can see it dance around and move as it gets excited with you," said Jacob Andreou, corporate vice president of product and growth for Microsoft AI, in an interview with The Associated Press. "It's in this effort of really landing this AI companion that you can really feel."

In the U.S. only so far, Copilot users on laptops and phone apps can speak to Mico, which changes colors, spins around and wears glasses when in "study" mode. It's also easy to shut off, which is a big difference from Microsoft's Clippit, better known as Clippy and infamous for its persistence in offering advice on word processing tools when it first appeared on desktop screens in 1997. "It was not well-attuned to user needs at the time," said Bryan Reimer, a research scientist at the Massachusetts Institute of Technology. "Microsoft pushed it, we resisted it and they got rid of it. I think we're much more ready for things like that today..."

Microsoft's product releases Thursday include a new option to invite Copilot into a group chat, an idea that resembles how AI has been integrated into social media platforms like Snapchat, where Andreou used to work, or Meta's WhatsApp and Instagram. But Andreou said those interactions have often involved bringing in AI as a joke to "troll your friends," in contrast to Microsoft's designs for an "intensely collaborative" AI-assisted workplace.

Speaking of the new MacBook Pro, which Apple launched on Wednesday, Bloomberg News reports that the company is preparing to launch a touch-screen version of its Mac computer, reversing course on a stance that dates back to co-founder Steve Jobs. From the report: The company is readying a revamped MacBook Pro with a touch display for late 2026 or early 2027 [non-paywalled link], according to people with knowledge of the matter. The new machines, code-named K114 and K116, will also have thinner and lighter frames and run the M6 line of chips. In making the move, Apple is following the rest of the computing industry, which embraced touch-screen laptops more than a decade ago.

The company has taken years to formulate its approach to the market, aiming to improve on current designs. Bloomberg News first reported in January 2023 that Apple was working on a touch-screen MacBook Pro. The new laptops will feature displays with OLED technology, the same standard used in iPhones and iPad Pros, said the people, who asked not to be identified because the products haven't been announced. It will mark the first time that this higher-end, thinner system is used in a Mac.

At CES in January, Nvidia's CEO Jensen Huang "stood flanked by 14 humanoid robots from different companies," remembers the Washington Post. But how close are we to real-world robot deployments?

Agility Robotics "says its factory is designed to eventually manufacture 10,000 robots a year," the Post adds (with "some" of its robots "already at work in e-commerce warehouses and auto parts factories.") Amazon even invested $150 million in the 10-year-old company (spun out from Oregon State University's robotics lab) in 2022, according to the article, "and has tested the company's robots in its warehouses." The e-commerce revolution has spawned sprawling warehouses across the country where products must be organized and customer orders assembled and shipped, but some human workers have said the repetitive work is low paid and leaves them prone to injury. Agility rents out its robots to warehouse owners it says have struggled to keep their human jobs filled, including logistics company GXO, which uses them at a warehouse for Spanx shapewear in Flowery Branch, Georgia, northeast of Atlanta. The robots pick up baskets of clothing from wheeled robots and walk them over to conveyor belts that take them to other parts of the facility.

Agility Chief Business Officer Daniel Diez said facilities like this represent a first step for humanoid robots into gainful employment. "This work gets paid, and we have eyes on large-scale deployments just doing this, and that's what we're focused on," he said. German auto parts company Schaeffler uses Agility robots to load and unload equipment at a factory in Cheraw, South Carolina. Auto part plants have become a favored proving ground for humanoid robots, with Boston Dynamics, the company famous for its videos of back-flipping robots, doing tests with its majority owner, Hyundai.
But meanwhile, RoboForce makes a robot that has two arms on a base with four wheels, the article notes, "providing stability and making it possible to lift more weight than a bipedal robot." Humanoid designs make sense "if it is so important to justify the trade-off and sacrifice of other things," RoboForce CEO Leo Ma tells the Post. "Other than that, there is a great invention called wheels."

Still, the article argues there's "a new drive to make humanoid robots practical," fueled by "the surge of investment in AI" combined with advancements in robotics that "make humanoid designs more capable and affordable." Years of steady progress have made legged robots better at balancing and stepping through tricky terrain. Improved batteries allow them to operate for longer without trailing industrial power cords. AI developers are adapting the innovations behind services like ChatGPT to help humanoids act more independently... The progress has triggered a frenzy of investment in humanoid robots and made them into a mascot for the idea that AI will soon reorder the world on the scale tech leaders have promised... Venture capitalists have invested over $5 billion in humanoid robotics start-ups since the beginning of 2024, according to financial data firm Pitchbook, and the largest tech corporations are also placing bets... Meta is working on integrating its own AI technology with humanoid robots, and Google researchers are collaborating with Austin-based humanoid robot start-up Apptronik... A host of humanoid robot companies has spawned in China, the world leader in complex manufacturing, where the government is subsidizing the industry. Six of the 14 robots that shared the stage with Nvidia's Huang were made by Chinese companies; five were American.

An anonymous reader quotes a report from TechCrunch: SpaceX has long marketed Starship as a fully and rapidly reusable rocket that's designed to deliver thousands of pounds of cargo to Mars and make life multiplanetary. But reusability at scale means a space vehicle that can tolerate mishaps and faults, so that a single failure doesn't spell a mission-ending catastrophe. The 10th test flight on Tuesday evening demonstrated SpaceX's focus on fault tolerance. In a post-flight update, SpaceX said the test stressed "the limits of vehicle capabilities." Understanding these edges will be critical for the company's plans to eventually use Starship to launch Starlink satellites, commercial payloads, and eventually astronauts.

When the massive Starship rocket lifted off on its 10th test flight Tuesday evening, SpaceX did more than achieve new milestones. It purposefully introduced several faults to test the heat shield, propulsion redundancy, and the relighting of its Raptor engine. The heat shield is among the toughest engineering challenges facing SpaceX. As Elon Musk acknowledged on X in May 2024, a reusable orbital return heat shield is the "biggest remaining problem" to 100% rocket reusability. The belly of the upper stage, also called Starship, is covered in thousands of hexagonal ceramic and metallic tiles, which make up the heat shield. Flight 10 was all about learning how much damage the ship can accept and survive when it goes through atmospheric heating. During the tenth test, engineers intentionally removed tiles from some sections of the ship, and experimented with a new type of actively cooled tile, to gather real-world data and refine designs. [...]

Propulsion redundancy was also put to the test. The Super Heavy booster's landing burn configuration appeared to be a rehearsal for engine failure. Engineers intentionally disabled one of the three center Raptor engines during the final phase of the burn and used a backup engine in its place. That was a successful rehearsal for an engine-out event. Finally, SpaceX reported the in-space relight of a Raptor engine, described on the launch broadcast as the second time SpaceX has pulled this off. Reliable engine restarts will be necessary for deep-space missions, propellant transfers, and possibly some payload deployment missions. [...] The next step is translating Flight 10 data into future hardware upgrades to move closer to routine operations and days when, as Musk envisioned, "Starship launches more than 24 times in 24 hours."

Google has released (PDF) a new analysis of its AI's environmental impact, showing that it has cut the energy use of AI text queries by a factor of 33 over the past year. Each prompt now consumes about 0.24 watt-hours -- the equivalent of watching nine seconds of TV. An anonymous reader shares an excerpt from an Ars Technica article: "We estimate the median Gemini Apps text prompt uses 0.24 watt-hours of energy, emits 0.03 grams of carbon dioxide equivalent (gCO2e), and consumes 0.26 milliliters (or about five drops) of water," they conclude. To put that in context, they estimate that the energy use is similar to about nine seconds of TV viewing. The bad news is that the volume of requests is undoubtedly very high. The company has chosen to execute an AI operation with every single search request, a compute demand that simply didn't exist a couple of years ago. So, while the individual impact is small, the cumulative cost is likely to be considerable.

The good news? Just a year ago, it would have been far, far worse. Some of this is just down to circumstances. With the boom in solar power in the US and elsewhere, it has gotten easier for Google to arrange for renewable power. As a result, the carbon emissions per unit of energy consumed saw a 1.4x reduction over the past year. But the biggest wins have been on the software side, where different approaches have led to a 33x reduction in energy consumed per prompt.

The Google team describes a number of optimizations the company has made that contribute to this. One is an approach termed Mixture-of-Experts, which involves figuring out how to only activate the portion of an AI model needed to handle specific requests, which can drop computational needs by a factor of 10 to 100. They've developed a number of compact versions of their main model, which also reduce the computational load. Data center management also plays a role, as the company can make sure that any active hardware is fully utilized, while allowing the rest to stay in a low-power state.

The other thing is that Google designs its own custom AI accelerators, and it architects the software that runs on them, allowing it to optimize both sides of the hardware/software divide to operate well with each other. That's especially critical given that activity on the AI accelerators accounts for over half of the total energy use of a query. Google also has lots of experience running efficient data centers that carries over to the experience with AI. The result of all this is that it estimates that the energy consumption of a typical text query has gone down by 33x in the last year alone.

A new review of nearly 700 studies on portable air cleaners found that over 90% of them were tested in empty spaces, not on people, leaving major gaps in evidence about whether these devices actually prevent infections or if they might even cause harm by releasing chemicals like ozone or formaldehyde. The Conversation reports: Many respiratory viruses, such as COVID-19 and influenza, can spread through indoor air. Technologies such as HEPA filters, ultraviolet light and special ventilation designs -- collectively known as engineering infection controls -- are intended to clean indoor air and prevent viruses and other disease-causing pathogens from spreading. Along with our colleagues across three academic institutions and two government science agencies, we identified and analyzed every research study evaluating the effectiveness of these technologies published from the 1920s through 2023 -- 672 of them in total.

These studies assessed performance in three main ways: Some measured whether the interventions reduced infections in people; others used animals such as guinea pigs or mice; and the rest took air samples to determine whether the devices reduced the number of small particles or microbes in the air. Only about 8% of the studies tested effectiveness on people, while over 90% tested the devices in unoccupied spaces.

We found substantial variation across different technologies. For example, 44 studies examined an air cleaning process called photocatalytic oxidation, which produces chemicals that kill microbes, but only one of those tested whether the technology prevented infections in people. Another 35 studies evaluated plasma-based technologies for killing microbes, and none involved human participants. We also found 43 studies on filters incorporating nanomaterials designed to both capture and kill microbes -- again, none included human testing.

14 months ago a jury ruled against Boeing, awarding $81 million in damages to failed electric airplane startup Zunum. "Zunum alleged that Boeing, while ostensibly investing seed money to get the startup off the ground, stole Zunum's technology and actively undermined its attempts to build a business," the Seattle Times reported at the time.

But two months later that verdict was overturned, Reuters reports, with U.S. District Judge James Robart deciding that Zunum "did not adequately identify its secrets or show that they derived their value from being kept secret."

And then three days ago a U.S. appeals court reinstated the original $81 million award, reversing that district judge's decision and "rejecting his finding that the information Boeing allegedly stole was not entitled to trade-secret protection." [T]he district court erred in concluding that "Zunum failed to identify any of its alleged trade secrets with sufficient particularity"... Here, the court rejected Zunum's repeated attempts to introduce comprehensive trade secret definitions into evidence and instead provided the jury with a court-created exhibit enumerating Zunum's alleged trade secrets with a short description of each. Zunum's witnesses identified the trade secrets by number, provided a basic explanation of each, and used exhibits and demonstratives to exemplify information comprising specific trade secrets.
"internal Boeing communications introduced at trial suggesting that Boeing intended to modify its own in-house designs, methods, and strategies to incorporate information from certain Zunum trade secrets..." according to the new ruling. "Under the parties' agreement, Boeing was not permitted to use Zunum's confidential information for any reason other than to manage its investment in Zunum."

Reuters adds that "A spokesperson for Boeing declined to comment on the appeals court's decision"

One final note: The appeals court also ordered the case to be assigned to a new judge after Robart revealed that his wife had acquired Boeing stock through a retirement savings account during the litigation.
Judge Robart had called that an "error". (And judicial ethics experts interviewed by Business Insider in 2024 "characterized Robart's trades and delayed disclosure to the parties as a minor issue," they reported Thursday.)

But Thursday's ruling notes that the delayed disclosure "taken together with the district court's consistent rulings in Boeing's favor during and after trial, could give an objective observer reason to question the district judge's impartiality in further proceedings."

Twenty years after Michelin introduced the Tweel in 2005, airless tires remain absent from passenger vehicles despite their promise to "eliminate nearly 200 million scrap tires a year caused by flats and underinflation," according to Michelin's internal testing cited in a Jalopnik report. Current prototypes "tend to transfer more road noise and vibration into the cabin than traditional radials -- making the ride harsher, especially at highway speeds." Heat dissipation poses additional challenges as "airless designs -- particularly those with internal webbing or solid cores -- have fewer ways to shed thermal load." The added structural mass "can affect fuel economy and increase unsprung weight -- bad news for handling and suspension tuning." Federal regulations compound these technical barriers since vehicle tires are subject to rigorous performance standards, many of which assume air pressure as a baseline.

alternative_right shares an interview from The Register with David W. Hill, who served as lead designer for ThinkPad from 1995 to 2017. Here are some excerpts from the wide-ranging interview: Hill revealed that he tried several times to introduce additional laptops that had the famous "butterfly keyboard" found on the ThinkPad 701C. [...] Hill told The Register that he had wanted to make more ThinkPads with butterfly keyboards and had tried at least three times to make it happen -- in one case there was a prototype where only half of the keyboard moved -- but was never able to get there. Eventually, screens became big enough that there was no need to have a keyboard that expanded. However, Hill said, he thought about putting a butterfly keyboard on a netbook when they were a viable product category in the late aughts. [...]

One of the features Hill is most proud of developing is the ThinkLight, an overhead light located above the screen that lit up the entire keyboard and deck. Though the advent of keyboard backlights has made the ThinkLight redundant -- Lenovo discontinued it in 2013 -- it offers capabilities that backlights do not. If you want to place a paper on top of your keyboard, the LED will light it up, allowing you to see more than just your key legends. ... When designing the 25th anniversary ThinkPad, which came out in 2017, Hill brought back the ThinkLight, but he actually wanted to have -- for the first time -- two LEDs instead of one. The dual lights would have eliminated shadows and provided even better illumination, but unfortunately, this effort proved too costly to make it into the final product. [...]

When I asked Hill about products he wanted to come out with but never got to, he talked about an idea for portable workstations that would fold up like a laptop but have a separate keyboard and screen like a desktop when you put them on your desk. He collaborated with butterfly keyboard creator John Karidis on this concept, but couldn't make it ready for market. "We did a lot of experimentation with laptops that sort of unfolded to be more like a desktop: things where the display elevated or the keyboard would remove so you could use them like a workstation, rather than just being a clamshell with a hinge, you open and close," Hill recalled. "We did a lot of experimentation with that and got close a few times, but never could completely sell it. I always thought it was an opportunity to create a new category."
