Study by the University of Bonn shows that positive effects are still evident even six weeks later:

A short-term oat-based diet appears to be surprisingly effective at reducing the cholesterol level. This is indicated by a trial by the University of Bonn, which has now been published in the journal Nature Communications. The participants suffered from a metabolic syndrome – a combination of high body weight, high blood pressure, and elevated blood glucose and blood lipid levels. They consumed a calorie-reduced diet, consisting almost exclusively of oatmeal, for two days. Their cholesterol levels then improved significantly compared to a control group. Even after six weeks, this effect remained stable. The diet apparently influenced the composition of microorganisms in the gut. The metabolic products, produced by the microbiome, appear to contribute significantly to the positive effects of oats.

The fact that oats have a beneficial effect on the metabolism is nothing new. German medic Carl von Noorden treated patients with diabetes with the cereal at the beginning of the 20th century – with remarkable success. "Today, effective medications are available to treat patients with diabetes," explains Marie-Christine Simon, junior professor at the Institute of Nutritional and Food Science at the University of Bonn. "As a result, this method has been almost completely overlooked in recent decades."

Although the test subjects in the current trial were not diabetic, they suffered from a metabolic syndrome associated with an increased risk of diabetes. The characteristics include excess body weight, high blood pressure, an elevated blood sugar level, and lipid metabolism disorders. "We wanted to know how a special oat-based diet affects patients," explains Simon, who is also a member of the Transdisciplinary Research Areas "Life & Health" and „Sustainable Futures" at the University of Bonn.

The participants were asked to exclusively eat oatmeal, which they had previously boiled in water, three times a day. They were only allowed to add some fruit or vegetables to their meals. A total of 32 women and men completed this oat-based diet. They ate 300 grams of oatmeal on each of the two days and only consumed around half of their normal calories. A control group was also put on a calorie-reduced diet, although this did not consist of oats.

Both groups benefited from the change in diet. However, the effect was much more pronounced for the participants who followed the oat-based diet. "The level of particularly harmful LDL cholesterol fell by 10 percent for them – that is a substantial reduction, although not entirely comparable to the effect of modern medications," stresses Simon. "They also lost two kilos in weight on average and their blood pressure fell slightly."

[...] But how does oatmeal exert its beneficial effect? "We were able to identify that the consumption of oatmeal increased the number of certain bacteria in the gut," explains Simon's colleague Linda Klümpen, the lead author of the trial. The microbiome has increasingly been the focus of research in recent decades. After all, it is now known that intestinal bacteria play a decisive role in metabolizing food. They also release the metabolic by-products that they create into their environment. They supply, among other things, the cells of the gut with energy, enabling them to better perform their tasks.

In addition, the microbes send some of their products around the body in the blood stream, where they can have various effects. "For instance, we were able to show that intestinal bacteria produce phenolic compounds by breaking down the oats," says Klümpen. "It has already been shown in animal studies that one of them, ferulic acid, has a positive effect on the cholesterol metabolism. This also appears to be the case for some of the other bacterial metabolic products." At the same time, other microorganisms "dispose of" the amino acid histidine. The body otherwise turns this into a molecule that is suspected of promoting insulin resistance. This insensitivity to insulin is a key feature of diabetes mellitus.

A large amount of oats for two days better than a small amount for six weeks

The positive effects of the oat-based diet tended to still be evident six weeks later. "A short-term oat-based diet at regular intervals could be a well-tolerated way to keep the cholesterol level within the normal range and prevent diabetes," says Junior Professor Simon. However, in the current study, the cereal above all exerted its effect at a high concentration and in conjunction with a calorie reduction: A six-week diet, in which the participants consumed 80 grams of oats per day, without any other restrictions, achieved small effects. "As a next step, it can now be clarified whether an intensive oat-based diet repeated every six weeks actually has a permanently preventative effect," continues Simon.

An industry report claims that video games are losing the attention war to gambling, porn, and crypto:

A new report by Epyllion, a gaming industry advisory company headed by venture capitalist and market guru Matthew Ball, has broken down the state of the video game industry, and has published data indicating the medium is losing the war for people's attention to other ventures, including gambling, crypto, and pornography.

The report, a lengthy 164-page presentation which you can (and should) read yourself, dedicates a whole section called "Video Games are losing the attention war in the 'Major Market 8'" to the topic. It starts by comparing pre and post pandemic consumer spending from eight major video game markets - the USA, Japan, South Korea, UK, Germany, France, Canada, and Italy.

Prior to the pandemic, these countries made up over 60 percent of total spending on video games. Post-pandemic, almost all of these regions have seen a drop in gaming population. In the US, 2.5-4 points worth of players stopped playing video games, the Canadian Trade Association found in its latest report that roughly one-in-six players prior to the pandemic have stopped playing.

These decreases in participation have resulted, the report posits, in a drop in spending. In the US, PC and console spend is down eight percent since 2020 / 2021, which comes to roughly $2.3bn. Mobile gaming's US annual growth in terms of spending has largely flattened since 2025, but it's still above 12 percent compared to 2020, and now beats out console spend.

Total spend across all "Major Market 8" regions on console and PC shrunk by $4.8bn, and mobile is down by $2.3bn, all while five of these eight markets are at all-time highs in terms of total spend. This money is instead going elsewhere, to Roblox for example, which the report states makes up 67 percent of net growth.

[...]

During this 2025 period, AI apps that allowed for "role play, erotica, and art" have soared. The latest tracked statistic for installs for this software came to just under one billion worldwide.

Prediction markets, where users can bet on events that happen in the world, also had a recent boom in popularity. Users placed 1.5m bets a day during Q4 2025. Online Sports Betting is also taking potential users' money. In 2025, US net losses due to sports betting passed $17bn, a 35x increase from 2019 as these sorts of services become normalised, legalised, and integrated into sports in the USA. Despite bans in other countries, international net losses are around $53bn a year.

[...]

The report states: "Video Gaming's post-pandemic problem isn't that players choose to watch TikTok instead of buying a AAA game, or subscribe to Onlyfans instead of buying a PlayStation; it's that on a Friday evening, players are placing a growing share of their time and spend elsewhere."

from the thanks-Einstein dept.

Astronomers have found thousands of exoplanets around single stars, but few around binary stars — even though both types of stars are equally common. Physicists can now explain the dearth:

Of the more than 4,500 stars known to have planets, one puzzling statistic stands out. Even though nearly all stars are expected to have planets and most stars form in pairs, planets that orbit both stars in a pair are rare.

Of the more than 6,000 extrasolar planets, or exoplanets, confirmed to date — most of them found by NASA's Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS) — only 14 are observed to orbit binary stars. There should be hundreds. Where are all the planets with two suns, like Tatooine in Star Wars?

Astrophysicists at the University of California, Berkeley, and the American University of Beirut have now proposed a reason for this dearth of circumbinary exoplanets — and Einstein's general theory of relativity is to blame.

In most binary star systems, the stars have similar but not identical masses and orbit one another in an egg-shaped or elliptical orbit. If a planet is orbiting the pair of stars, the gravitational tugs from the stars make the planet's orbit precess, meaning the orbital axis rotates similar to the way the axis of a spinning top rotates or precesses in Earth's gravity.

The orbit of the binary stars also precesses, but mainly because of general relativity. Over time, tidal interactions between the binary pair shrink the orbit, which has two effects: The precession rate of the stars increases, but the precession rate of the planet slows. When the two precession rates match, or resonate, the planet's orbit becomes wildly elongated, taking it farther from the star but also nearer at its closest approach.

"Two things can happen: Either the planet gets very, very close to the binary, suffering tidal disruption or being engulfed by one of the stars, or its orbit gets significantly perturbed by the binary to be eventually ejected from the system," said Mohammad Farhat, a Miller Postdoctoral Fellow at UC Berkeley and first author of the paper. "In both cases, you get rid of the planet."

That doesn't mean that binary stars don't have planets, he cautioned. But the only ones that survive this process are too far from the stars for us to detect with transit techniques used by Kepler and TESS.

"There are surely planets out there. It's just that they are difficult to detect with current instruments," said co-author Jihad Touma, a physics professor at the American University of Beirut.

[...] Farhat points out that binaries have an instability zone around them in which no planet can survive. Within that zone, the three-body interactions between the two stars and the planet either expel the planet from the system or pull it close enough to merge with or be shredded by the stars. Peculiarly, 12 of the 14 known transiting exoplanets around tight binaries are just beyond the edge of the instability zone, where they apparently migrated from farther away, since planets would have a hard time forming there.

"Planets form from the bottom up, by sticking small-scale planetesimals together. But forming a planet at the edge of the instability zone would be like trying to stick snowflakes together in a hurricane," he said.

[...] Proposed by Albert Einstein in 1915, the general theory of relativity interprets gravity as a warping of the fabric of spacetime by a mass, analogous to how a person on a trampoline warps the surface and makes other objects on the trampoline fall inward. Mercury's orbit happens to be closest to the gravitational warp of the sun and, as a result, experiences an orbital precession slightly higher than predicted by the earlier theory of gravity laid out by Isaac Newton. The general relativistic explanation for the additional precession of Mercury's orbit more than a century ago was the first confirmation of Einstein's theory.

The same effect comes into play when any two objects get close to one another, such as tight-knit binary stars. Binary stars likely begin their lives far apart, but as they interact with surrounding gas during the formation of their star system, it's predicted that many pairs will move closer together over tens of millions of years. When they do, they generate tides in one another that slowly, over billions of years, shrink the orbit even more. Eventually, as they tighten to periods of around a week or less, general-relativistic precession becomes increasingly important. This makes the orbit precess, which means that the point of closest approach, or periastron, also rotates. As the stars get closer and closer, the rate of precession increases.

A circumbinary exoplanet also sees its elliptical axis precess, in this case because of the gravitational tug of the two stars — a strictly Newtonian process. However, as the binaries move closer to one another, their perturbation of the planet gradually weakens and the precession slows down.

As the orbital precession of the binary stars increases and that of the exoplanet decreases, at some point they match and enter a state of resonance. At this point, calculations show, the exoplanet's orbit starts to elongate, taking it farther from the binary at the extreme point of its orbit but closer at periastron. When periastron enters the zone of instability, the exoplanet is either exiled to the far reaches of the system or approaches too close to the binary and is engulfed. Because this disruption occurs quickly, taking a few tens of millions of years within the multibillion-year lifetime of a star, exoplanets around tight binaries end up being very rare.

"A planet caught in resonance finds its orbit deformed to higher and higher eccentricities, precessing faster and faster while staying in tune with the orbit of the binary, which is shrinking," Touma said. "And on the route, it encounters that instability zone around binaries, where three-body effects kick into place and gravitationally clear out the zone."

"Just the natural way you form these tight binaries, these sub-seven-day binaries, you get rid of the planet naturally, without invoking additional disruption from a nearby star or other mechanisms," Farhat said.

Red Hat's toolkit offers governments and enterprises a way to measure the control they actually have over their data, infrastructure, and operations in this era of geopolitical cloud anxiety:

Over the past year, several governments and companies outside the US have decided they can't trust American tech companies. So, digital sovereignty has become an important goal. While American companies, as you can imagine, aren't happy about that, they're now helping European organizations to achieve their digital sovereignty goals.

One of the first of these was Linux and cloud-native computing powerhouse Red Hat. Late last year, Red Hat became the first US company to announce its own EU-specific digital sovereignty program, Red Hat Confirmed Sovereign Support (RHCSS). This initiative guarantees critical European IT operations remain under EU control.

Now, Red Hat is backing this initiative with its open-source Digital Sovereignty Readiness Assessment toolkit. This tool is designed to give governments and enterprises a concrete way to measure how much control they actually have over their data, infrastructure, and operations in an era of geopolitical cloud anxiety.

This new web-based, self-service survey walks organizations through 21 multiple-choice questions. Areas covered include data residency, encryption key control, disaster recovery planning for geopolitical events, and the ability to prevent sensitive data from crossing borders. The goal is to move digital sovereignty from vague policy talk to a measurable "sovereignty baseline" that IT and business leaders can act on.

[...] Red Hat's framework evaluates sovereignty maturity across seven domains: data sovereignty, technical sovereignty, operational sovereignty, assurance sovereignty, open source strategy, executive oversight, and managed services. At the end of the questionnaire, organizations receive a score mapped to four stages: foundation, developing, strategic, and advanced. It also includes a roadmap of recommended next steps and research questions for stakeholders.

[...] Of course, Red Hat hopes you'll turn to their services to achieve your digital sovereignty goal, but there's no requirement that you do so. You decide what to do with the analysis and whether you want to join one of the many other European-based governments, companies, and organizations that are waving goodbye to Amazon Web Services, Microsoft, or Google cloud services.

Mind you, all these US tech giants are also now offering their own digital sovereignty initiatives. The Digital Sovereignty Readiness Assessment toolkit can help you decide whether these US offerings meet your needs.

https://www.slashgear.com/2102659/mandatory-digital-vehicle-lien-title-illinois/

Since the dawn of the digital era, it's been the dream of many to have a totally paperless society. When the Jetsons first aired in 1962, the idea of a world that used screen-based technology instead of traditional paper media was a far-fetched, pie-in-the-sky notion. Here we are, over 60 years later, and although everyone now carries around pocket gizmos with more processing power than the computers aboard early Apollo spaceships that took men to the moon, we're still not a totally paperless society.

However, several states are making efforts to help make that reality, at least in part, through Electronic Lien and Titling (ELT) programs. There are currently about 30 states actively using electronic vehicle title (e-title) programs to maintain their motor vehicle records. These digital versions carry the same details (i.e., the owner's personal information, the Vehicle Identification Number, make, model, and year) and are considered just as valid as old paper documents. What's more, since they're in digital form rather than an actual paper document, they can't be lost or stolen.

The latest state to join the digital revolution is Illinois. Alexi Giannoulias, the Illinois Secretary of State, announced in early February 2026 that "moving to mandatory Electronic Lien and Titling is the next step in bringing Illinois' vehicle services fully into the digital age." He went on to say that this secure, paperless method will cut down on the red tape normally involved and, as a result, speed up the entire process (including transferring a car's title) from what used to take weeks or months — to mere hours.

The Illinois General Assembly first approved the ELT program all the way back in 2000, but outdated technology prevented a full implementation. When Giannoulias took office in 2023, he set out to update that technology and, in 2024, finally got the program up and running. Now, all Driver's Services Facilities in Illinois – as well as every financial institution that processes five or more liens annually – will be required to switch over to this new digital system by July 1, 2026.

The new online ELT program will allow liens and title records to be transmitted directly to the Secretary of State, where they're kept electronically by approved service providers. It should eliminate the time and cost of mailing and storing paper documents and allow lien and title records to be viewed in real time. Additionally, owners will be spared the hassle of physically trudging down to their nearest DMV to deal with these issues in person (after undoubtedly standing in long lines). Furthermore, it should increase accuracy and keep rejection rates below 0.1%.

Once a loan is fully paid off, financial institutions can then instantly release the vehicle title (of which there are several types you should know about). No more waiting around for it to arrive at its final destination via snail mail, where it can easily go missing, which in turn helps protect against criminal activity such as "title washing" and fraudulent lien releases. Criminals are notorious for intercepting these documents in the mail and then removing (or washing off) information like liens or the fact that it was stolen from a vehicle's title to create a false "clean title."

Concrete "battery" developed at MIT now packs 10 times the power:

Concrete already builds our world, and now it's one step closer to powering it, too. Made by combining cement, water, ultra-fine carbon black (with nanoscale particles), and electrolytes, electron-conducting carbon concrete (ec3, pronounced "e-c-cubed") creates a conductive "nanonetwork" inside concrete that could enable everyday structures like walls, sidewalks, and bridges to store and release electrical energy. In other words, the concrete around us could one day double as giant "batteries."

As MIT researchers report in a new PNAS paper, optimized electrolytes and manufacturing processes have increased the energy storage capacity of the latest ec3 supercapacitors by an order of magnitude. In 2023, storing enough energy to meet the daily needs of the average home would have required about 45 cubic meters of ec3, roughly the amount of concrete used in a typical basement. Now, with the improved electrolyte, that same task can be achieved with about 5 cubic meters, the volume of a typical basement wall.

"A key to the sustainability of concrete is the development of 'multifunctional concrete,' which integrates functionalities like this energy storage, self-healing, and carbon sequestration. Concrete is already the world's most-used construction material, so why not take advantage of that scale to create other benefits?" asks Admir Masic, lead author of the new study, MIT Electron-Conducting Carbon-Cement-Based Materials Hub (EC³ Hub) co-director, and associate professor of civil and environmental engineering (CEE) at MIT.

The improved energy density was made possible by a deeper understanding of how the nanocarbon black network inside ec3 functions and interacts with electrolytes. Using focused ion beams for the sequential removal of thin layers of the ec3 material, followed by high-resolution imaging of each slice with a scanning electron microscope (a technique called FIB-SEM tomography), the team across the EC³ Hub and MIT Concrete Sustainability Hub was able to reconstruct the conductive nanonetwork at the highest resolution yet. This approach allowed the team to discover that the network is essentially a fractal-like "web" that surrounds ec3 pores, which is what allows the electrolyte to infiltrate and for current to flow through the system.

"Understanding how these materials 'assemble' themselves at the nanoscale is key to achieving these new functionalities," adds Masic.

Equipped with their new understanding of the nanonetwork, the team experimented with different electrolytes and their concentrations to see how they impacted energy storage density. As Damian Stefaniuk, first author and EC³ Hub research scientist, highlights, "we found that there is a wide range of electrolytes that could be viable candidates for ec3. This even includes seawater, which could make this a good material for use in coastal and marine applications, perhaps as support structures for offshore wind farms."

At the same time, the team streamlined the way they added electrolytes to the mix. Rather than curing ec3 electrodes and then soaking them in electrolyte, they added the electrolyte directly into the mixing water. Since electrolyte penetration was no longer a limitation, the team could cast thicker electrodes that stored more energy.

The team achieved the greatest performance when they switched to organic electrolytes, especially those that combined quaternary ammonium salts — found in everyday products like disinfectants — with acetonitrile, a clear, conductive liquid often used in industry. A cubic meter of this version of ec3 — about the size of a refrigerator — can store over 2 kilowatt-hours of energy. That's about enough to power an actual refrigerator for a day.

While batteries maintain a higher energy density, ec3 can in principle be incorporated directly into a wide range of architectural elements — from slabs and walls to domes and vaults — and last as long as the structure itself.

"The Ancient Romans made great advances in concrete construction. Massive structures like the Pantheon stand to this day without reinforcement. If we keep up their spirit of combining material science with architectural vision, we could be at the brink of a new architectural revolution with multifunctional concretes like ec3," proposes Masic.

Taking inspiration from Roman architecture, the team built a miniature ec3 arch to show how structural form and energy storage can work together. Operating at 9 volts, the arch supported its own weight and additional load while powering an LED light.

However, something unique happened when the load on the arch increased: the light flickered. This is likely due to the way stress impacts electrical contacts or the distribution of charges. "There may be a kind of self-monitoring capacity here. If we think of an ec3 arch at architectural scale, its output may fluctuate when it's impacted by a stressor like high winds. We may be able to use this as a signal of when and to what extent a structure is stressed, or monitor its overall health in real time," envisions Masic.

The latest developments in ec³ technology bring it a step closer to real-world scalability. It's already been used to heat sidewalk slabs in Sapporo, Japan, due to its thermally conductive properties, representing a potential alternative to salting. "With these higher energy densities and demonstrated value across a broader application space, we now have a powerful and flexible tool that can help us address a wide range of persistent energy challenges," explains Stefaniuk. "One of our biggest motivations was to help enable the renewable energy transition. Solar power, for example, has come a long way in terms of efficiency. However, it can only generate power when there's enough sunlight. So, the question becomes: How do you meet your energy needs at night, or on cloudy days?"

Franz-Josef Ulm, EC³ Hub co-director and CEE professor, continues the thread: "The answer is that you need a way to store and release energy. This has usually meant a battery, which often relies on scarce or harmful materials. We believe that ec3 is a viable substitute, letting our buildings and infrastructure meet our energy storage needs." The team is working toward applications like parking spaces and roads that could charge electric vehicles, as well as homes that can operate fully off the grid.

"What excites us most is that we've taken a material as ancient as concrete and shown that it can do something entirely new," says James Weaver, a co-author on the paper who is an associate professor of design technology and materials science and engineering at Cornell University, as well as a former EC³ Hub researcher. "By combining modern nanoscience with an ancient building block of civilization, we're opening a door to infrastructure that doesn't just support our lives, it powers them."

Researchers at MIT have developed electron-conducting carbon concrete, a new kind of cement "that can store and release electricity like batteries," reports Matthew Burgos for Design Boom. "MIT's concrete battery shows a future where the material can be embedded into roads or parking areas to charge electric vehicles directly, or for off-grid homes that do not need external power," Burgos explains.

Privacy is prerequisite for free thought, dissent, experimentation, and innovation, which are in turn prerequisites for democracy. At NBTV, Naomi Brockwell has posted four reasons why limits on privacy are absolutely not a price worth paying for mainstream adoption.

Today I participated in a Privacy Salon in Denver where we debated a proposition that cuts to the core of the modern privacy movement:

"Limits on privacy are a price worth paying for mainstream adoption of cryptographic privacy."

I was on the "no" side alongside Matt Green, with Evin McMullen and Wei Dai arguing "yes."

It was a lively, thoughtful exchange that forced us to confront a deeper question: is weakening privacy simply the cost of scale?

Below is my opening statement from the debate.

The false argument about having nothing to hide does not hold water. As Ed Snowden observed years ago, "arguing that you don't care about the right to privacy because you have nothing to hide is no different than saying you don't care about free speech because you have nothing to say."

Penn Medicine researchers find that earplugs work better in protecting sleep from traffic noise, challenging the widespread use of ambient sound machines and apps marketed as sleep aids:

Pink noise—a continuous sound spread across a wide range of frequencies often used to promote sleep—may reduce restorative REM sleep and interfere with sleep recovery. In contrast, earplugs were found to be significantly more effective in protecting sleep against traffic noise, according to a new study published in the journal Sleep from the Perelman School of Medicine.

The findings challenge the widespread use of ambient sound machines and apps marketed as sleep aids.

"REM sleep is important for memory consolidation, emotional regulation and brain development, so our findings suggest that playing pink noise and other types of broadband noise during sleep could be harmful—especially for children whose brains are still developing and who spend much more time in REM sleep than adults," says study lead author Mathias Basner, professor of sleep and chronobiology in psychiatry.

In a sleep laboratory during eight-hour sleep opportunities over seven consecutive nights, the participants' exposure to aircraft noise—compared to none—was associated with about 23 fewer minutes per night spent in N3, the deepest sleep stage. Earplugs prevented this drop in deep sleep to a large extent. Pink noise alone at 50 decibels (often compared to the sound of a "moderate rainfall") was associated with a nearly 19-minute decrease in REM sleep.

If pink noise was combined with aircraft noise, both deep sleep and REM sleep were significantly shorter compared to noise-free control nights, and time spent awake was now also 15 minutes longer, which had not been observed in aircraft noise-only or pink noise-only nights.

Participants also reported that their sleep felt lighter, they woke up more frequently, and their overall sleep quality was worse when exposed to aircraft noise or pink noise, compared to nights without noise—unless they used earplugs.

A while back, Freenet Africa had a nice background piece about software luminary and founder of the software freedom movement, Richard Stallman (aka RMS). The article covers his background starting with the GNU project and following through to the current, ongoing fight for digital freedom.

A Rebel with a Cause

Imagine a world where every time you want to share a cool app with a friend, you have to ask permission (and maybe pay extra). Or where fixing a simple bug in your game is impossible because the code is locked away like a secret recipe. Sounds like a tech dystopia, right? This is exactly the kind of world Richard Stallman set out to prevent. Stallman – often known just by his initials RMS – is not as instantly famous as tech giants like Bill Gates or Steve Jobs, but his impact on our digital lives is monumental. He's the mastermind behind the GNU Project, the founder of the Free Software Foundation (FSF), and the author of licenses that guarantee software freedom. In short, he's the original software freedom fighter, a kind of digital rights Gandalf (yes, with the beard to match). And for a guy who champions "free" software, he's quick to tell you: we're talking free as in freedom, not just free as in price.

In this essay, we'll dive into Richard Stallman's contributions to the digital world in an engaging (and occasionally humorous) way. By the end, you'll understand how his work laid the foundation for Linux and the whole open-source ecosystem, why he insists on calling it "GNU/Linux," and what the internet might look like if Stallman hadn't started his crusade for software freedom. Grab a snack (maybe some free-as-in-freedom nachos?) and let's explore the world of Stallman and the movement he started.

Who is Richard Stallman? (And Why Should You Care?) [...]

As others have pointed out, the freedom is the start of a journey, not the destination.

NASA releases "Starliner Propulsion System Anomalies during the Crewed Flight Test"

https://www.nasa.gov/news-release/nasa-releases-report-on-starliner-crewed-flight-test-investigation/

To quote Cheryl Warner, NASA News Chief, "At a news conference on Thursday, NASA released a report of findings from the Program Investigation Team examining the Boeing CST-100 Starliner Crewed Flight Test as part of the agency's Commercial Crew Program."

The direct link to the redacted report is:

https://www.nasa.gov/wp-content/uploads/2026/02/nasa-report-with-redactions-021926.pdf?emrc=76e561

Redacted? "For the full report, which includes redactions in coordination with our commercial partner to protect proprietary and privacy-sensitive material is available online."

Its 311 pages and they're not providing a summary so it is likely to be extremely juicy and spicy, as NASA historically doesn't water down press releases for many other reasons. So I know what I'll be reading with breakfast tea later this morning.

So the facts are above. My separate opinions below.

I'd give it a different take than the report as I've read it so far; they designed a semi-disposable cost-reduced capsule but space projects ALWAYS take longer so if backflowing oxidizer will inevitably very slowly eat the o-rings in the helium manifold, well, its going to sit around a long time before launching so its going to eat thru, thats the nature of space program delays. Or propellant residue plus CO2 will rot out thruster nozzles given enough time, and space programs being space programs they will indeed be given time to sit around and slowly rot. They still are not sure about the RCS thrusters jamming but it seems likely to be a lack of ground testing during R+D; teflon is like a viscous liquid over a long time while under stress, key being over a long time.

The "Hardware Longevity and Sparing Concerns" section hints to me that the program is about to be cancelled if it doesn't cancel itself first. Reads like they're not permitted under the terms of the investigation to recommend program shutdown but they wanted to recommend it anyway.

The report follows that with numerous identified management failures at NASA and Boeing. This is the new Boeing, which is no longer competent, so "NASA's hands-off contract approach limited insight" precisely when Boeing needed adult supervision as they've downsized, outsourced, refused to recruit, or otherwise eliminated their competent adults for various reasons over the years. But who knows, what do y'all think?

NASA Admits Starliner Failures as It Preps for March Launch of Artemis 2

The agency's administrator promises transparency and accountability:

NASA aims to launch its next crewed moon mission, Artemis II, as soon as March 6, after a key fueling test showed major progress and only minor issues.

[...] The announcement of the potential Artemis II launch date, NASA's first astronaut-led moon mission since 1972, comes a day after the agency admitted to gross failures in the Boeing Starliner test flight that involved astronauts Butch Wilmore and Suni Williams in 2024. NASA administrator Jared Isaacman delivered scathing remarks about the risk to human safety during a Thursday news conference about the investigation, which relabeled the Starliner mission as a "Type-A mishap." That designation is the most serious level of incident short of a fatal accident.

With Artemis II set to become the first human test flight of the Orion spaceship, there are some glaring parallels, especially given concerns about the spacecraft's heat shield. Though the lunar mission uses a different rocket and spacecraft from Boeing's long-troubled Starliner, leaders stressed that the mishap investigation must reshape how NASA manages all human spaceflight. The same cultural and management failures could surface in any program if left unchecked, said NASA associate administrator Amit Kshatriya.

"We failed them," he said, referring to Wilmore and Williams, who both retired after their 10-day test flight turned into nine months at the International Space Station. "Even though they won't say that, we have to say that."

Isaacman outlined how the agency mishandled the 2024 mission, citing serious failures in NASA's own leadership and decision-making. NASA has released its 300-page Starliner report, days ahead of plans to present the findings to Congress.

NASA and Boeing still don't fully understand why thrusters in both the service module — which carries engines and fuel — and the capsule malfunctioned. The crewed mission had a temporary loss of steering during its approach to the station and another propulsion failure during its empty return, though that wasn't made public at the time. The two astronauts were not on board for that, coming home instead in a SpaceX Crew Dragon months later.

In a statement released Thursday, Boeing said it had made substantial progress on technical repairs since the flight and was working on cultural changes across its team as well.

"NASA's report will reinforce our ongoing efforts to strengthen our work, and the work of all Commercial Crew Partners, in support of mission and crew safety, which is and must always be our highest priority," the company said.

It opens inside Bing in your default browser:

Last year, we reported on a speed test feature coming to Windows, built right into the taskbar, where you could gauge your internet connection without venturing out to a browser. In reality, it was more like a shortcut that would still open Bing and take you to a miniaturized version of Ookla's Speedtest. Today, that feature is finally here in the Insider program, as part of Build 26100.7918 and 26200.7918.

In these updates pushed to the Release Preview channel, you'll now see an option to "Perform speed test" when you right-click on the network icon or open the Wi-Fi/cellular quick settings. Upon clicking, your default browser will open up Bing, where you'll see a simplified Ookla interface with a meter in the middle, and three stats below: Latency, Download, and Upload.

That means this is technically not a "native" feature, rather just a website link in your taskbar. Still, for the uninitiated, it can be a convenient way to check their internet speed. Let's say you're in a game and suddenly start experiencing packet loss; instead of Alt-tabbing into a browser for a speed test, you can just right-click on your Ethernet icon and go there directly.

This feature will save you a click or two; however, some users may be disappointed by yet another web wrapper implemented inside Windows. Windows has enjoyed a poor run of stability recently, with even Microsoft recognizing its slack, so a built-in taskbar speedtest is probably not high on most users' list of priorities.

Amazon did us all a service recently by airing a Super Bowl commercial showing how Ring doorbell cameras spy on everyone walking past. (I discussed this on Techtonic this week with Chris Gilliard, aka hypervisible: episode page / podcast. Recommended listening.)

In the instant that that image aired, millions of Americans finally understood what I – and other tech critics – have been trying to warn about for years: networked cameras are spying on you. The blue circles show the reach of Ring cameras, and – crucially – indicate that they're all part of one network, controlled by Amazon, which can share or sell data to any number of third parties.

Researchers have described a novel mechanochemical process that can store gases safely in powders, using very little energy, in a repeatable process:

Australian scientists say they've made a "eureka moment" breakthrough in gas separation and storage that could radically reduce energy use in the petrochemical industry, while making hydrogen much easier and safer to store and transport in a powder.

Nanotechnology researchers, based at Deakin University's Institute for Frontier Materials, claim to have found a super-efficient way to mechanochemically trap and hold gases in powders, with potentially enormous and wide-ranging industrial implications.

Mechanochemistry is a relatively recently coined term, referring to chemical reactions that are triggered by mechanical forces as opposed to heat, light, or electric potential differences. In this case, the mechanical force is supplied by ball milling – a low-energy grinding process in which a cylinder containing steel balls is rotated such that the balls roll up the side, then drop back down again, crushing and rolling over the material inside.

The team has demonstrated that grinding certain amounts of certain powders with precise pressure levels of certain gases can trigger a mechanochemical reaction that absorbs the gas into the powder and stores it there, giving you what's essentially a solid-state storage medium that can hold the gases safely at room temperature until they're needed. The gases can be released as required, by heating the powder up to a certain point.

The process is repeatable, and Professor Ian Chen, co-author on the new study published in the journal Materials Today, tells us via phone that the boron nitride powder used in the first experiments only loses "about a couple of percent" of its absorption capability each storage and release cycle. "Boron nitride is very stable," he tells us, "and graphene too. We're looking at a restoration treatment that can clean the powders and restore their absorption levels, but we need to prove that it'll work."

The results are absolutely remarkable from a numbers standpoint. This process, for example, could separate hydrocarbon gases out from crude oil using less than 10% of the energy that's needed today. "Currently, the petrol industry uses a cryogenic process," says Chen. "Several gases come up together, so to purify and separate them, they cool everything down to a liquid state at very low temperature, and then heat it all together. Different gases evaporate at different temperatures, and that's how they separate them out."

Cryogenics, of course, is a highly energy-intensive process, and the Deakin team found that its ball milling process could be tuned to separate out gases just as effectively using far less energy. Different gases, they found, are absorbed at different milling intensities, gas pressures and time periods. Once the first gas is absorbed into the powder, it can be removed, and the process can be re-run with a different set of parameters to trap and store the next gas. Likewise, some gases are released from the powders at higher temperatures than others, offering a second way to separate gases if they're stored together.

In the team's experiments, they managed to separate out a combination of alkyne, olefin and paraffin gases using boron nitride powder. The process takes a while – some gases were fully absorbed after two hours, others were still only partially soaked up after 20 hours. But Chen says this should just be a matter of fine-tuning: "We're continuing to work on different gases, using different materials. We hope to have another paper published soon, and we also expect to work with industry on some real practical applications."

[...] The gas separation use case would be a pretty huge advance all by itself, but by storing gas securely in powders, the team believes it's also unlocked a compelling way to store and transport hydrogen, which could play a key role in the coming clean energy transition.

[...] With hydrogen safely stored in the powder, it can be moved around and warehoused extremely easily and safely – this could be a very compelling way to move bulk quantities of hydrogen for export or distribution, since it's both cheaper and easier to handle than gas or liquid, and the equipment needed to release the gas for use at the other end will be pretty simple.

[...] Boron nitride is easily available in industrial quantities, and relatively cheap, but Chen says the technique should work with other materials as well. "We're not limited to boron nitride," he says, "we're just using it as an example. You could also use graphene, to take another example, and we're continuing to investigate other materials."

Clearly, this advance has some potentially enormous implications, which could contribute greatly to energy use reduction, emissions reduction, the green energy transition and even reducing fuel and chemical prices. The team has submitted provisional patent applications, and we look forward to learning what's possible as the method is refined and tailored to useful applications.

Cosmic mystery of the impossibly high-energy neutrino solved by "dark charge" model of black holes :

In 2023, a subatomic particle called a neutrino crashed into Earth with an impossibly huge amount of energy. In fact, no known sources anywhere in the universe can produce that much energy, 100,000 times more than the highest-energy particle ever produced by the Large Hadron Collider, Earth's most powerful particle accelerator. However, a team of physicists at the University of Massachusetts Amherst recently hypothesized that something like this could happen when a special kind of black hole, called a quasi-extremal primordial black hole, explodes.

Black holes exist, and we have a good understanding of their life cycle: an old, large star runs out of fuel, implodes in a massively powerful supernova, and leaves behind an area of spacetime with such intense gravity that nothing, not even light, can escape. These black holes are incredibly heavy and are essentially stable.

But, as physicist Stephen Hawking pointed out in 1970, another kind of black hole – a primordial black hole – could be created not by the collapse of a star, but from the universe's primordial conditions shortly after the Big Bang. Primordial black holes exist only in theory so far. And, like standard black holes, they're so massively dense that almost nothing can escape them ... which is what makes them black. However, despite their density, primordial black holes could be much lighter than the black holes we have so far observed. Furthermore, Hawking showed that primordial black holes could slowly emit particles via what is now known as Hawking radiation if they got hot enough.

Andrea Thamm, co-author of the new research and assistant professor of physics at UMass Amherst, said:

The lighter a black hole is, the hotter it should be and the more particles it will emit. As primordial black holes evaporate, they become ever lighter, and so hotter, emitting even more radiation in a runaway process until explosion. It's that Hawking radiation that our telescopes can detect.

If such an explosion were to be observed, it would give us a definitive catalog of all the subatomic particles in existence. That would include the ones we have observed, such as electrons, quarks and Higgs bosons. And also the ones that we have only hypothesized, like dark matter particles, as well as everything else that is, so far, entirely unknown to science. The UMass Amherst team has previously shown that such explosions could happen with surprising frequency – every decade or so – and if we were to pay attention, our current cosmos-observing instruments could register these explosions.

Then, in 2023, an experiment called the KM3NeT Collaboration captured that impossible neutrino. It was exactly the kind of evidence the UMass Amherst team hypothesized we might soon see.

[...] Co-author Joaquim Iguaz Juan, a postdoctoral researcher in physics at UMass Amherst, said:

We think that primordial black holes with a 'dark charge' – what we call quasi-extremal primordial black holes – are the missing link.

The dark charge is essentially a copy of the usual electric force as we know it. But it includes a very heavy, hypothesized version of the electron, which the team calls a dark electron.

Co-author Michael Baker, an assistant professor of physics at UMass Amherst, said:

There are other, simpler models of primordial black holes out there. Our dark-charge model is more complex, which means it may provide a more accurate model of reality. What's so cool is to see that our model can explain this otherwise unexplainable phenomenon.

Thamm added:

A primordial black hole with a dark charge has unique properties and behaves in ways that are different from other, simpler primordial black hole models. We have shown that this can provide an explanation of all of the seemingly inconsistent experimental data.

https://gizmodo.com/theres-a-new-term-for-workers-freaking-out-over-being-replaced-by-ai-2000723019

There isn't a ton of evidence to suggest that the introduction of AI has led to significant job losses, yet. But it has led to a significant amount of talk about job losses, and that appears to be taking a real toll on people. According to research published in the journal Cureus and spotted by Futurism, workers are increasingly suffering from distress caused by the constant fear of being replaced, and it's gotten so bad that it needs its own term.

The researchers propose calling this new, modern anxiety "AI replacement dysfunction" or AIRD. The authors define it as a "new, proposed clinical construct describing the psychological and existential distress that could be experienced by individuals facing the threat or reality of job displacement due to artificial intelligence (AI)." The condition carries with it several common symptoms including anxiety, insomnia, depression, and identity confusion "that may reflect deeper fears about relevance, purpose, and future employability." It can also lead to sufferers dealing with additional challenges like psychiatric disorders and substance abuse.

The anxiety over AI is definitely real. A recent Reuters/Ipsos poll found that 71% of respondents said they were concerned that AI will put "too many people out of work permanently." Pew Research found that more than half of Americans are worried about how AI in the workplace will impact their jobs, and most lower- and middle-class people believe AI will worsen their job prospects in the future. Another study found that people working in jobs particularly susceptible to automation are more likely to report feeling more stress and other negative emotions.

And while surprisingly few job cuts have actually been attributed to AI directly (despite the fact that many companies have used AI as cover for broader layoffs), there certainly does seem to be damage being done to the workforce, as it relates to entry-level roles, in particular. Early-career workers are definitely having a much harder time finding jobs, which can at least in part be attributed to companies being more willing to turn over that labor to AI. But the reality is that the economy sucks regardless of the introduction of technological innovation, and the companies responsible for building AI benefit from the narrative that their models are capable of doing human-level work. So hearing about AI taking over your job is basically unavoidable, whether the threat is real or not.

While AIRD isn't an accepted clinical diagnosis yet, the researchers have created a framework to help identify it, including a screening questionnaire designed to help clinicians spot potential symptoms. Treatments for the condition will be up to the clinician, but the researchers highlight Cognitive Behavioral Therapy and other cognitive restructuring techniques to "help patients build psychological resilience and restore a coherent sense of self."
