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

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

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

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

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

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

"Oracle has informed us they won't voluntarily withdraw their trademark on 'JavaScript'." That's the word coming from the company behind Deno, the alternative JavaScript/TypeScript/WebAssembly runtime, which is pursuing a formal cancellation with the U.S. Patent and Trademark Office.

So what happens next? Oracle "will file their Answer, and we'll start discovery to show how 'JavaScript' is widely recognized as a generic term and not controlled by Oracle." Deno's social media posts show a schedule of various court dates that extend through July of 2026, so "The dispute between Oracle and Deno Land could go on for quite a while," reports InfoWorld: Deno Land co-founder Ryan Dahl, creator of both the Deno and Node.js runtimes, said a formal answer from Oracle is expected before February 3, unless Oracle extends the deadline again. "After that, we will begin the process of discovery, which is where the real legal work begins. It will be interesting to see how Oracle argues against our claims — genericide, fraud on the USPTO, and non-use of the mark."

The legal process begins with a discovery conference by March 5, with discovery closing by September 1, followed by pretrial disclosure from October 16 to December 15. An optional request for an oral hearing is due by July 8, 2026.
Oracle took ownership of JavaScript's trademark in 2009 when it purchased Sun Microsystems, InfoWorld notes.

But "Oracle does not control (and has never controlled) any aspect of the specification or how the phrase 'JavaScript' can be used by others," argues an official petition filed by Deno Land Inc. with the United States Patent and Trademark Office: Today, millions of companies, universities, academics, and programmers, including Petitioner, use "JavaScript" daily without any involvement with Oracle. The phrase "JavaScript" does not belong to one corporation. It belongs to the public. JavaScript is the generic name for one of the bedrock languages of modern programming, and, therefore, the Registered Mark must be canceled.

An open letter to Oracle discussing the genericness of the phrase "JavaScript," published at https://javascript.tm/, was signed by 14,000+ individuals at the time of this Petition to Cancel, including notable figures such as Brendan Eich, the creator of JavaScript, and the current editors of the JavaScript specification, Michael Ficarra and Shu-yu Guo. There is broad industry and public consensus that the term "JavaScript" is generic.
The seven-page petition goes into great detail, reports InfoWorld. "Deno Land also accused Oracle of committing fraud in its trademark renewal efforts in 2019 by submitting screen captures of the website of JavaScript runtime Node.js, even though Node.js was not affiliated with Oracle."

An anonymous reader quotes a report from Rolling Stone: Sun pours through the lush foliage of a jungle, bleaching the pale limestone as a rotting man stands in the center of an otherwise empty arena, his yellow eyes leering from beneath a fringe of limp, blonde hair. Positioned around the edge are a hundred bodies, Orcs and Trolls and bipedal oxen shouting, demanding, the death of the dishonorable. Their voices swell into a cacophony of noise before one rings out above the rest, howling, 'Kill the cheater and you'll get 20 gold!' There is silence, and then another frenzy. As I watch, eyes fixed on the dim glow of a laptop screen, I think of the colosseum in Rome -- sweat running down the muscled arms of battle-tested gladiators, the crowd cheering for blood.

This might sound like a moment pulled from a high fantasy drama made for prestige TV, but this is World of Warcraft, a now 20-year old online RPG. Instead of actors parading in front of green screens, this story's cast are streamers that occupy a virtual world. Tensions are high not because they're scripted, but because in World of Warcraft's Hardcore mode, death is permanent. Dejected, though acknowledging the transgression made, Sequisha -- the streamer who was promptly executed for cheating -- sighs, and goes back to the character select screen. He creates a new avatar; it's time to start the game all over again.

Sequisha's execution and subsequent reincarnation is just one of hundreds of stories playing out everyday in World of Warcraft as streamers have flocked to the massively multiplayer online RPG (MMORPG) to play together. Through their strife, and a commitment to staying in-character via roleplay, groups like the guild OnlyFangs have turned World of Warcraft into an RPG within an RPG, playing out improvisational personal drama where the stakes are high. In Hardcore mode, World of Warcraft has become the best soap opera on the internet, all playing out across over dozens of OnlyFangs creator streams every day. The new "Classic" and "Hardcore" servers were launched in celebration of World of Warcraft's 20th anniversary, helping to reignite interest in the game and increase viewership on platforms like Twitch and YouTube. The Hardcore server, where character death is permanent, attracted top streamers, leading to the formation of guilds like OnlyFangs.

After a successful first season, OnlyFangs reshuffled its roster, embracing a more immersive roleplaying approach in its second season. "What they didn't know was their experiment in World of Warcraft roleplay would inadvertently create one of the best emergent dramas on the internet," reports Rolling Stone.

The Washington Post shares some good news from 2024: Researchers were able to detect a significant dip in atmospheric levels of hydrochlorofluorocarbons — harmful gases that deplete the ozone layer — for the first time, almost 30 years after countries first agreed to phase out the chemicals.

A new satellite launched in March to track and publicly reveal the biggest methane polluters in the oil and gas industry — an important step in tackling the greenhouse gas that accounts for almost a third of global warming. The NASA/Carbon Mapper satellite, which measures CO2 and methane emissions, also launched, providing detailed images from individual oil and gas facilities across the world.

Back on Earth, the world's largest plant for pulling carbon dioxide out of the atmosphere opened in Iceland. Norway became the first country to have more electric than gas-powered vehicles, while one Japanese island began using a new generation of batteries to help stockpile massive amounts of clean electricity.

There were also small but important victories for animal conservation. The Iberian lynx, a European wildcat once on the brink of extinction, is no longer classed as an "endangered" species — in what experts have hailed as the "greatest recovery of a cat species ever achieved through conservation...."

Despite a large number of powerful tornadoes to hit the United States in early 2024, the death tolls were fortunately not as high as meteorologists feared, in part due to improved forecasting technology.
The article also notes America's Food and Drug Administration approved a new therapy which uses a patients' own cells to attack skin cancer for adults for whom surgery isn't an option. "Experts said the decision could open the door to similar treatments for far more common cancers."

Following its record-breaking closest approach to the Sun, NASA's Parker Solar Probe has transmitted a beacon tone back to Earth indicating it's in good health and operating normally. NASA: The mission operations team at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland received the signal just before midnight EST, on the night of Dec. 26. The team was out of contact with the spacecraft during closest approach, which occurred on Dec. 24, with Parker Solar Probe zipping just 3.8 million miles from the solar surface while moving about 430,000 miles per hour.

The spacecraft is expected to send back detailed telemetry data on its status on Jan. 1. This close-up study of the Sun allows Parker Solar Probe to take measurements that help scientists better understand how material in this region gets heated to millions of degrees, trace the origin of the solar wind (a continuous flow of material escaping the Sun), and discover how energetic particles are accelerated to near light speed. Previous close passes have helped scientists pinpoint the origins of structures in the solar wind and map the outer boundary of the Sun's atmosphere.

NASA's Parker Solar Probe made a historic approach on Christmas Eve, flying within 3.8 million miles of the Sun at a record-breaking speed of 430,000 mph. It marks humanity's closest encounter with a star. Live Science reports: Mission control cannot communicate with the probe during this rendezvous due to its vicinity to the sun, and will only know how the spacecraft fared in the early hours of Dec. 27 after a beacon signal confirms both the flyby's success and the overall state of the spacecraft. Images gathered during the flyby will beam home in early January, followed by scientific data later in the month when the probe swoops further away from the sun, Nour Rawafi, who is the project scientist for the mission, told reporters at the Annual Meeting of the American Geophysical Union (AGU) earlier this month.

Parker launched in 2018 to help decode some of the biggest mysteries about our sun, such as why its outermost layer, the corona, heats up as it moves further from the sun's surface, and what processes accelerate charged particles to near-light speeds. In addition to revolutionizing our understanding about the sun, the probe also caught rare closeups of passing comets and studied the surface of Venus. On Christmas Eve, scientists expect the probe to have flown through plumes of plasma still attached to the sun, and hope it observed solar flares occurring simultaneously due to ramped-up turbulence on the sun's surface, which spark breathtaking auroras on Earth but also disrupt communication systems and other technology. "Right now, Parker Solar Probe has achieved what we designed the mission for," Nicola Fox, the associate administrator for NASA Science Mission Directorate at NASA Headquarters in Washington, D.C., said in a NASA video released on Dec. 24. "It's just a total 'Yay! We did it' moment."

"Voyager 1 is currently exploring interstellar space at a distance of 15.5 billion miles (24.9 billion kilometers) away from Earth," writes Gizmodo.

And yet a team of amateur astronomers in the Netherlands was able to receive Voyager's signals on a 1950s-era telescope... The astronomers used orbital predictions of Voyager 1's position in space to correct for the Doppler shift in frequency caused by the motion of Earth, as well as the motion of the spacecraft through space... [The signal] was found live, and further analysis later confirmed that it corresponded to the position of Voyager 1.
"I did the experiment," mathematician/scientific software engineer Tammo Jan Dijkema told Slashdot in an email, as "one of a crew of four." He works at ASTRON (the Netherlands Institute for Radio Astronomy) while volunteering at the Dwingeloo radio telescope, and wants to clarify any suggestion in Gizmodo's article "that we received signals at S-band, which is not true. We received the 'normal' Voyager-1 signal at 8.4 GHz. See our blog post... The Dwingeloo reception was not related to Voyager's temporary glitch at all."

And Scientific American shares an interesting perspective on the Voyager probes: we everyday Earthlings may simplistically think of the sun as a compact distant ball of light, in part because our plush atmosphere protects us from our star's worst hazards. But in reality the sun is a roiling mass of plasma and magnetism radiating itself across billions of miles in the form of the solar wind, which is a constant stream of charged plasma that flows off our star. The sun's magnetic field travels with the solar wind and also influences the space between planets. The heliosphere grows and shrinks in response to changes in the sun's activity levels over the course of an 11-year cycle... [Jamie Rankin, a space physicist at Princeton University and deputy project scientist of the Voyager mission] notes, astronomers of all stripes are trapped within that chaotic background in ways that may or may not affect their data and interpretations. "Every one of our measurements to date, until the Voyagers crossed the heliopause, has been filtered through all the different layers of the sun," Rankin says.

On their trek to interstellar space, the Voyagers had to cross a set of boundaries: first a termination shock some seven billion or eight billion miles away from the sun, where the solar wind abruptly begins to slow, then the heliopause, where the outward pressure from the solar wind is equaled by the inward pressure of the interstellar medium. Between these two stark borders lies the heliosheath, a region where solar material continues to slow and even reverse direction. The trek through these boundaries took Voyager 1, the faster of the twin probes, nearly eight years; such is the vastness of the scale at play.

Beyond the heliopause is interstellar space, which Voyager 1 entered in 2012 and Voyager 2 reached in 2018. It's a very different environment from the one inside our heliosphere — quieter but hardly quiescent. "It's a relic of the environment the solar system was born out of," Rankin says of the interstellar medium. Within it are energetic atomic fragments called galactic cosmic rays, as well as dust expelled by dying stars across the universe's eons, among other ingredient.
Earlier this month Wired noted " The secret of the Voyagers lies in their atomic hearts: both are equipped with three radioisotope thermoelectric generators, or RTGs — small power generators that can produce power directly on board. Each RTG contains 24 plutonium-238 oxide spheres with a total mass of 4.5 kilograms..." But as time passes, the plutonium on board is depleted, and so the RTGs produce less and less energy. The Voyagers are therefore slowly dying. Nuclear batteries have a maximum lifespan of 60 years. In order to conserve the probes' remaining energy, the mission team is gradually shutting down the various instruments on the probes that are still active...

Four active instruments remain, including a magnetometer as well as other instruments used to study the galactic environment, with its cosmic rays and interstellar magnetic field. But these are in their last years. In the next decade — it's hard to say exactly when — the batteries of both probes will be drained forever.

NASA's Parker Solar Probe will make its closest approach yet to the Sun on Christmas Eve, flying within 3.8 million miles of the solar surface and entering its atmosphere for the first time.

The spacecraft, which travels at speeds up to 430,000 miles per hour, aims to study the origins of solar wind -- the stream of charged particles emanating from the Sun's corona. The probe's heat shield will endure temperatures exceeding 2,500-degree Fahrenheit during the flyby, requiring specialized materials like sapphire crystal tubes and niobium wiring to protect its instruments.

Today a group of German scientists presented data suggesting Earth is absorbing more sunlight than in the past, reports Ars Technica, "largely due to reduced cloud cover." We can measure both the amount of energy the Earth receives from the Sun and how much energy it radiates back into space.... The new paper finds that the energy imbalance set a new high in 2023, with a record amount of energy being absorbed by the ocean/atmosphere system. This wasn't accompanied by a drop in infrared emissions from the Earth, suggesting it wasn't due to greenhouse gases, which trap heat by absorbing this radiation. Instead, it seems to be due to decreased reflection of incoming sunlight by the Earth....

Using two different data sets, the teams identify the areas most effected by this, and they're not at the poles, indicating loss of snow and ice are unlikely to be the cause. Instead, the key contributor appears to be the loss of low-level clouds [particularly over the Atlantic ocean]... The drop in low-level clouds had been averaging about 1.3 percent per decade. 2023 saw a slightly larger drop occur in just one year....

So, what could be causing the clouds to go away? The researchers list three potential factors. One is simply the variability of the climate system, meaning 2023 might have just been an extremely unusual year, and things will revert to trends in the ensuing years. The second is the impact of aerosols, which both we and natural processes emit in copious quantities. These can help seed clouds, so a reduction of aerosols (driven by things like pollution control measures) could potentially account for this effect. The most concerning potential explanation, however, is that there may be a feedback relationship between rising temperatures and low-level clouds. Meaning that, as the Earth warms, the clouds become sparse, enhancing the warming further. That would be bad news for our future climate, because it suggests that the lower range of warming estimates would have to be adjusted upward to account for it.
If the decline in reflectivity wasn't just caused by normal variability, the researchers warn, "the 2023 extra heat may be here to stay..."

To help replace power plants, Japan's northernmost island, Hokkaido, "is turning to a new generation of batteries designed to stockpile massive amounts of energy," reports the Washington Post.

"The Hokkaido Electric Power Network (HEPCO Network) is deploying flow batteries, an emerging kind of battery that stores energy in hulking tanks of metallic liquid." [F]low batteries are making their debut in big real-world projects. Sumitomo Electric, the company that built the Hokkaido plant, has also built flow batteries in Taiwan, Belgium, Australia, Morocco and California. Hokkaido's flow battery farm was the biggest in the world when it opened in April 2022 — a record that lasted just a month before China built one that is eight times bigger and can deliver as much energy as an average U.S. natural gas plant. "It looks like flow batteries are finally about to take off with interest from China," said Michael Taylor, an energy analyst at the International Renewable Energy Agency, an international group that studies and promotes green energy. "When China starts to get comfortable with a technology and sees it working, then they will very quickly scale their manufacturing base if they think they can drive down the costs, which they usually can...."

Lithium-ion batteries are perfect for smartphones because they're lightweight and fit in small spaces, even if they don't last long and have to be replaced frequently. Utilities have a different set of priorities: They need to store millions of times more energy, and they have much more room to work with. "If you think about utility-scale stationary applications, maybe you don't need lithium-ion batteries. You can use another one that is cheaper and can provide the services that you want like, for example, vanadium flow batteries," said Francisco Boshell, a researcher at the International Renewable Energy Agency...

Flow batteries are designed to tap giant tanks that can store a lot of energy for a long time. To boost their storage capacity, all you have to do is build a bigger tank and add more vanadium. That's a big advantage: By contrast, there's no easy way to adjust the storage capacity of a lithium-ion battery — if you want more storage, you have to build a whole new battery... One major barrier to building more of these battery farms is finding enough vanadium. Three-quarters of the world's supply comes as a by-product from 10 steel mills in China and Russia, according to Kara Rodby [a battery analyst at the investment firm Volta Energy Technologies] who got her PhD at the Massachusetts Institute of Technology studying the design and market for flow batteries. Australia, South Africa and the United States also produce vanadium, but in much smaller quantities. Mines that have been proposed could boost supply. And some flow battery start-ups are trying to sidestep the vanadium problem entirely by using different materials that are easier to buy.

The other hurdle is their up-front cost. Vanadium flow batteries are at least twice as expensive to build as lithium-ion batteries, Rodby said, and banks are hesitant to lend money to fund an unfamiliar technology. But experts say flow batteries can be cheaper in the long run because they're easier to maintain and last longer. A lithium-ion battery might have to be replaced after 10 years, but Rodby says flow batteries can last much longer. "There really is no finite lifetime for a flow battery in the way there is for lithium-ion," Rodby said.
Here's an interesting statistic from the article. "Over the next six years, utilities will have to build 35 times as many batteries as there are today to soak up all extra renewable energy that will come online, according to the International Energy Agency."

"Polar oceans constitute emission hotspots during the summer," according to a new paper published in the peer-reviewed scientific journal Science Advances. "And including those sea-to-air fluxes in an atmospheric chemistry-climate model "results in a net radiative effect that has far-reaching implications."

The research was led by a team of scientists from Spain's Institute of Marine Sciences and the Blas Cabrera Institute of Physical Chemistry, according to an announcement from the UK's University of East Anglia: Researchers have quantified for the first time the global emissions of a sulfur gas produced by marine life, revealing it cools the climate more than previously thought, especially over the Southern Ocean. The study, published in the journal Science Advances, shows that the oceans not only capture and redistribute the sun's heat, but produce gases that make particles with immediate climatic effects, for example through the brightening of clouds that reflect this heat.

It broadens the climatic impact of marine sulfur because it adds a new compound, methanethiol, that had previously gone unnoticed. Researchers only detected the gas recently, because it used to be notoriously hard to measure and earlier work focussed on warmer oceans, whereas the polar oceans are the emission hotspots...

Their findings represent a major advance on one of the most groundbreaking theories proposed 40 years ago about the role of the ocean in regulating the Earth's climate. This suggested that microscopic plankton living on the surface of the seas produce sulfur in the form of a gas, dimethyl sulphide, that once in the atmosphere, oxidizes and forms small particles called aerosols. Aerosols reflect part of the solar radiation back into space and therefore reduce the heat retained by the Earth. Their cooling effect is magnified when they become involved in making clouds, with an effect opposite to, but of the same magnitude as, that of the well-known warming greenhouse gases, such as carbon dioxide or methane. The researchers argue that this new work improves our understanding of how the climate of the planet is regulated by adding a previously overlooked component and illustrates the crucial importance of sulfur aerosols. They also highlight the magnitude of the impact of human activity on the climate and that the planet will continue to warm if no action is taken.
The article includes this quote from one of the study's lead authors (Dr. Charel Wohl from the university's Centre for Ocean and Atmospheric Sciences). "Climate models have greatly overestimated the solar radiation actually reaching the Southern Ocean, largely because they are not capable of correctly simulating clouds. The work done here partially closes the longstanding knowledge gap between models and observations."

And the university's announcement argues that "With this discovery, scientists can now represent the climate more accurately in models that are used to make predictions of +1.5 degrees C or +2 degrees C warming, a huge contribution to policy making."

Crypto entrepreneur Justin Sun consumed Maurizio Cattelan's "Comedian" artwork -- a banana taped to a wall -- during an event in Hong Kong on Friday, declaring "the real value is the concept itself." Sun, founder of cryptocurrency platform Tron, purchased the piece for $6.2 million at Sotheby's last week, significantly above its $1-1.5 million estimate.

The acquisition included only a certificate of authenticity and assembly instructions, not the physical banana or tape. The Chinese-born entrepreneur, who faces SEC charges over fraud and securities violations, made the payment in cryptocurrency.

Software company Deno Land has filed a petition with the U.S. Patent and Trademark Office to cancel Oracle's JavaScript trademark, citing trademark abandonment and fraud. The November 22 filing claims Oracle has not sold JavaScript products or services since acquiring the trademark through its 2009 Sun Microsystems purchase. The petition alleges Oracle committed fraud during its 2019 trademark renewal by submitting Node.js website screenshots without authorization.

The legal action follows a September open letter from JavaScript creator Brendan Eich, Node.js and Deno creator Ryan Dahl, and other prominent JavaScript developers urging Oracle to relinquish the trademark. The letter has garnered over 14,000 signatures.

An asteroid named 2024 PT5, recently exhibiting "mini moon" behavior around Earth, may have been a boulder that was blasted off the moon by an impacting, crater-forming asteroid," reports the Associated Press. The 33-foot space rock is expected to pass safely near Earth in January, when it will be closely observed. From the report: While not technically a moon -- NASA stresses it was never captured by Earth's gravity and fully in orbit -- it's "an interesting object" worthy of study. The astrophysicist brothers who identified the asteroid's "mini moon behavior," Raul and Carlos de la Fuente Marcos of Complutense University of Madrid, have collaborated with telescopes in the Canary Islands for hundreds of observations so far.

Currently more than 2 million miles (3.5 million kilometers) away, the object is too small and faint to see without a powerful telescope. It will pass as close as 1.1 million miles (1.8 million kilometers) of Earth in January, maintaining a safe distance before it zooms farther into the solar system while orbiting the sun, not to return until 2055. That's almost five times farther than the moon. [...] NASA will track the asteroid for more than a week in January using the Goldstone solar system radar antenna in California's Mojave Desert, part of the Deep Space Network.

An anonymous reader quotes a report from VICE: It's early on a Sunday morning in late 1994, and you're shuffling your way through Fitzrovia in Central London, bloodstream still rushing after a long night at Bagley's. The sun comes up as you come down. You navigate side streets that you know like the back of your hand. But your hand's stamped with a party logo. And your brain's kaput. Coffee... yes, coffee. Good idea. Suddenly, you find yourself outside a teal blue cafe. Walking in is like entering an alien world; rows of club kids, tech heads, and game developers sit in front of desktops, lost in the primitive version of some new reality. Tentacular cables hang from the ceiling. Ambient techno reverberates from wall to wall. Cigarette smoke fills the air.

Welcome to Cyberia, the world's first internet cafe. Which, if you're too young to remember, are basically cafes with computers in them. It all began when Eva Pascoe, a Polish computing student living in London, crossed paths with Tim Berners Lee and other early internet mavericks at the dawn of the 90s. "I was very interested in cyberfeminism and wanted to figure out how women could reclaim tech," she recalls. The internet was still in its infancy. Diabolically slow dial-up modems only emerged around 1992; the World Wide Web was a pipe dream until 1993 and hardly anyone had the internet at home. But there wasn't just a lack of javascript; Eva remembers there being no good java, either. "There were no coffee shops in London," she says, which today seems ludicrous. "Just greasy spoons and everyone drank tea. I wanted a European-style cafe."

Linking up with like-minded pioneers David Rowe and husband and wife Keith and Gene Teare, Eva found a spot on the corner of Whitfield Street and launched Cyberia there in 1994. With Hackers-style aesthetics and futuristic furniture, it was based around a U-shaped layout that meant visitors could see each other's screens. "I wanted women to feel safe, because a lot of the stuff on the net was dodgy," she explains. Many of Eva's mates chipped in to help out -- architects, interior designers, graphic artists, publishers, and ravers among them.

And then there was the Amish community in Pennsylvania. Eva had to fly out there to negotiate for the "Cyberia.com" domain name they had bought. "It was a proper barn with horse carts and a wall of modems as they were running a bulletin board and an early ecommerce company. Apparently, there was always one family nominated to be the tech support," she remembers. Back in London, Cyberia quickly became a hotspot. "Virtually the second we opened, we had three lines deep around the block," she says. It's hard to imagine, but nowhere else in the world was doing what they were doing. It was the world's first cybercafe. "If you wanted to collect your emails, we were the only place in town," Eva says. Cyberia opened around 20 cafes worldwide, including branches in Bangkok, Paris, and Rotterdam. "For a fleeting moment it became like a sexier version of Richard Branson's Virgin empire: there was Cyberia Records, Cyberia Channel (a pioneering streaming service), Cyberia Payments, the Cyberia magazine, a Cyberia show on UK TV -- even a Cyberia wedding," writes VICE's Kyle MacNeill. He attended Cyberia's 30th birthday party in September and spoke with some of the cafe's original innovators, "shooting the shit about the good times and the not-so-good coffee."

Astronomers have discovered a supermassive black hole in the early Universe devouring matter at over 40 times the Eddington limit. ScienceAlert reports: Led by astronomer Hyewon Suh of Gemini Observatory and NSF's NOIRLab, a team of researchers used JWST to take follow-up observations of a smattering of galaxies identified by the Chandra X-ray Observatory that were bright in X-rays but dim in other wavelengths. When they got to LID-568, they were having trouble identifying its distance across space-time. The galaxy was very faint and very hard to see; but, using the integral field spectrograph on JWST's NIRSpec instrument, the team homed in on the galaxy's exact position. LID-568's far-off location is surprising. Although the object is faint from our position in the Universe, its distance means it must be incredibly intrinsically bright. Detailed observations revealed powerful outflows from the supermassive black hole, a signature of accretion as some of the material is being diverted and blasted into space.

A painstaking analysis of the data revealed that the supermassive black hole is a relatively small one, as supermassive black holes go; just 7.2 million times the mass of the Sun. And the amount of light being produced by the material around the disk was much, much higher than a black hole of this mass should be capable of producing. It suggests an accretion rate some 40 times higher than the Eddington limit. At this rate, the period of super-Eddington accretion should be extremely brief, which means Suh and her team were extremely lucky to catch it in action. And we expect that LID-568 will become a popular observation target for black hole scientists, allowing us a rare glimpse into super-Eddington processes. The research has been published in Nature Astronomy.

"It's that time again," writes USA Today, noting that Sunday morning millions of Americans (along with millions more in Canada, Europe, parts of Australia, and Chile) "will set their clocks back an hour, and many will renew their twice-yearly calls to put an end to the practice altogether..." Experts say the time changes are detrimental to health and safety, but agree that the answer isn't permanent DST. "The medical and scientific communities are unified ... that permanent standard time is better for human health," said Erik Herzog, a professor of biology and neuroscience at Washington University in St. Louis and the former president of the Society for Research on Biological Rhythms...

Springing forward an hour in March is harder on us than falling back in November. The shift in spring is associated with an increase in heart attacks, and car accident rates also go up for a few days after, he said. But the answer isn't permanent daylight saving time, according to Herzog, who said that could be even worse for human health than the twice-yearly changes. By looking at studies of people who live at the easternmost edge of time zones (whose experience is closest to standard time) and people who live at the westernmost edge (more like daylight saving time), scientists can tell that health impacts of earlier sunrises and sunsets are much better. Waking up naturally with the sun is far better for our bodies than having to rely on alarm clocks to wake up in the dark, he said.

Herzog said Florida, where [Senator Marco] Rubio has championed the Sunlight Protection Act, is much less impacted by the negative impacts of daylight saving time because it's as far east and south as you can get in the U.S., while people in a state like Minnesota would have much more time in the dark in the morning.
The article also reminds U.S. readers that "No state can adopt permanent daylight saving time unless U.S. Congress passes a law to authorize it first." Nevertheless... Oklahoma became the most recent state to pass a measure authorizing permanent daylight saving time, pending Congressional approval, in April. Nineteen other states have passed laws or resolutions to move toward daylight saving time year-round, if Congress were ever to allow it, according to the National Conference of State Legislatures...

Only two states and some territories never have to set their clocks forward or backward... [Hawaii and Arizona, except for the Navajo Nation.]

An anonymous reader quotes a report from The Guardian: A new global inventory has catalogued air pollution from space activities from 2020 to 2022. The inventory includes time, position and pollution from 446 launchers as they ascended and the tracks of re-entries as objects are heated to extreme temperatures and break up or burn up in the upper atmosphere. It catalogues the pollution from 63,000 tons of rocket propellants used in 2022 and from 3,622 objects, including rocket parts and satellites, that re-entered the atmosphere between 2020 and 2023, amounting to about 12,000 tons. [...]

Types of launch pollutants depend on the propellent but can include particles of soot and aluminum oxides as well as nitrogen oxides, chlorine and water vapour and carbon dioxide. Extreme heat on re-entry causes atmospheric oxygen and nitrogen to combine to form more nitrogen oxides and also produces tiny metal-oxide particles as the objects break and burn up. Soot emitted high in the atmosphere can persist for several years, with a resulting climate warming impact that is up to 500 times greater than the same amount of soot from aviation or ground-level sources. Aluminum oxide particles, nitrogen oxides and chloride can consume the ozone in the stratosphere that protects us from the sun's ultraviolet radiation. These can remain in the atmosphere for decades. Dr Connor Barker, of the UCL team, said: "Many rocket manufacturers and space agencies keep this information tightly controlled. We had to be creative about the different sources we consulted, from launch live streams on YouTube to online databases maintained by space enthusiasts in their spare time."

It was originally created back in 2005 by Sun Microsystems for its proprietary Solaris Unix systems, "for troubleshooting kernel and application problems on production systems in real time," explains Wikipedia. "DTrace can be used to get a global overview of a running system, such as the amount of memory, CPU time, filesystem and network resources used by the active processes," explains its Wikipedia entry.

But this week, Gentoo announced: The real, mythical DTrace comes to Gentoo! Need to dynamically trace your kernel or userspace programs, with rainbows, ponies, and unicorns — and all entirely safely and in production?! Gentoo is now ready for that!

Just emerge dev-debug/dtrace and you're all set. All required kernel options are already enabled in the newest stable Gentoo distribution kernel...

Documentation? Sure, there's lots of it. You can start with our DTrace wiki page, the DTrace for Linux page on GitHub, or the original documentation for Illumos. Enjoy!

NASA has revealed a full-scale prototype for six telescopes designed to detect gravitational waves. Phys.Org reports: The LISA (Laser Interferometer Space Antenna) mission is led by ESA (European Space Agency) in partnership with NASA to detect gravitational waves by using lasers to measure precise distances -- down to picometers, or trillionths of a meter -- between a trio of spacecraft distributed in a vast configuration larger than the sun. Each side of the triangular array will measure nearly 1.6 million miles, or 2.5 million kilometers.

The Engineering Development Unit Telescope, which was manufactured and assembled by L3Harris Technologies in Rochester, New York, arrived at Goddard in May. The primary mirror is coated in gold to better reflect the infrared lasers and to reduce heat loss from a surface exposed to cold space, since the telescope will operate best when close to room temperature.

The prototype is made entirely from an amber-colored glass-ceramic called Zerodur, manufactured by Schott in Mainz, Germany. The material is widely used for telescope mirrors and other applications requiring high precision because its shape changes very little over a wide range of temperatures. The LISA mission is slated to launch in the mid-2030s.
