"If NASA establishes a permanent presence on the moon, its astronauts' homes could be made of a new 3D-printable, waterless concrete," writes MIT Technology Review. "Someday, so might yours.

"By accelerating the curing process for more rapid construction, this sulfur-based compound could become just as applicable on our home terrain as it is on lunar soil..." Building a home base on the moon will demand a steep supply of moon-based infrastructure: launch pads, shelter, and radiation blockers. But shipping Earth-based concrete to the lunar surface bears a hefty price tag. Sending just 1 kilogram (2.2 pounds) of material to the moon costs roughly $1.2 million, says Ali Kazemian, a robotic construction researcher at Louisiana State University (LSU). Instead, NASA hopes to create new materials from lunar soil and eventually adapt the same techniques for building on Mars.

Traditional concrete requires large amounts of water, a commodity that will be in short supply on the moon and critically important for life support or scientific research, according to the American Society of Civil Engineers. While prior NASA projects have tested compounds that could be used to make "lunarcrete," they're still working to craft the right waterless material.

So LSU researchers are refining the formula, developing a new cement based on sulfur, which they heat until it's molten to bind material without the need for water. In recent work, the team mixed their waterless cement with simulated lunar and Martian soil to create a 3D-printable concrete, which they used to assemble walls and beams. "We need automated construction, and NASA thinks 3D printing is one of the few viable technologies for building lunar infrastructure," says Kazemian.

Beyond circumventing the need for water, the cement can handle wider temperature extremes and cures faster than traditional methods. The group used a pre-made powder for their experiments, but on the moon and Mars, astronauts might extract sulfur from surface soil.
Kazemian and his colleagues recently transferred the technology to NASA's Marshall Space Flight Center for further testing...

An anonymous reader shared this report from Reuters: The rapid increase in satellites and space junk will make low Earth orbit unusable unless companies and countries cooperate and share the data needed to manage that most accessible region of space, experts and industry insiders said. A United Nations panel on space traffic coordination in late October determined that urgent action was necessary and called for a comprehensive shared database of orbital objects as well as an international framework to track and manage them. More than 14,000 satellites including some 3,500 inactive surround the globe in low Earth orbit, showed data from U.S.-based Slingshot Aerospace. Alongside those are about 120 million pieces of debris from launches, collisions and wear-and-tear of which only a few thousand are large enough to track... [T]here is no centralised system that all space-faring nations can leverage and even persuading them to use such a system has many obstacles. Whereas some countries are willing to share data, others fear compromising security, particularly as satellites are often dual-use and include defence purposes. Moreover, enterprises are keen to guard commercial secrets.

In the meantime, the mess multiplies. A Chinese rocket stage exploded in August, adding thousands of fragments of debris to low Earth orbit. In June, a defunct Russian satellite exploded, scattering thousands of shards which forced astronauts on the International Space Station to take shelter for an hour... Projections point to tens of thousands more satellites entering orbit in the coming years. The potential financial risk of collisions is likely to be $556 million over five years, based on a modelled scenario with a 3.13% annual collision probability and $111 million in yearly damages, said Montreal-based NorthStar Earth & Space...

[Aarti Holla-Maini, director of the U.N . Office for Outer Space Affairs], said the October panel aimed to bring together public- and private-sector experts to outline steps needed to start work on coordination. It will present its findings at a committee meeting next year. Global cooperation is essential to developing enforceable rules akin to those used by the International Civil Aviation Organization for air traffic, industry experts told Reuters. Such effort would involve the use of existing tools, such as databases, telescopes, radars and other sensors to track objects while improving coverage, early detection and data precision. Yet geopolitical tension and reluctance to share data with nations deemed unfriendly as well as commercial concerns over protecting proprietary information and competitive advantages remain significant barriers. That leaves operators of orbital equipment relying on informal or semi-formal methods of avoiding collisions, such as drawing on data from the U.S. Space Force or groups like the Space Data Association. However, this can involve issues such as accountability and inconsistent data standards.

"The top challenges are speed — as consensus-building takes time — and trust," Holla-Maini said. "Some countries simply can't communicate with others, but the U.N. can facilitate this process. Speed is our biggest enemy, but there's no alternative. It must be done."
Data from Slingshot Aerospace shows a 17% rise in close approaches per satellite over the past year, according to the article. (It adds that SpaceX data "showed Starlink satellites performed nearly 50,000 collision-avoidance manoeuvres in the first half of 2024, about double the previous six months...)

The European Space Agency, which has fewer spacecraft than SpaceX, said in 2021 its manoeuvres have increased to three or four times per craft versus a historical average of one."

"Spacecraft, satellites, and space-based systems all face cybersecurity threats that are becoming increasingly sophisticated and dangerous," reports CNBC.

"With interconnected technologies controlling everything from navigation to anti-ballistic missiles, a security breach could have catastrophic consequences." Critical space infrastructure is susceptible to threats across three key segments: in space, on the ground segment and within the communication links between the two. A break in one can be a cascading failure for all, said Wayne Lonstein, co-founder and CEO at VFT Solutions, and co-author of Cyber-Human Systems, Space Technologies, and Threats. "In many ways, the threats to critical infrastructure on Earth can cause vulnerabilities in space," Lonstein said. "Internet, power, spoofing and so many other vectors that can cause havoc in space," he added. The integration of artificial intelligence into space projects has heightened the risk of sophisticated cyber attacks orchestrated by state actors and individual hackers. AI integration into space exploration allows more decision-making with less human oversight.

For example, NASA is using AI to target scientific specimens for planetary rovers. However, reduced human oversight could make these missions more prone to unexplained and potentially calamitous cyberattacks, said Sylvester Kaczmarek, chief technology officer at OrbiSky Systems, which specializes in the integration of AI, robotics, cybersecurity, and edge computing in aerospace applications. Data poisoning, where attackers feed corrupted data to AI models, is one example of what could go wrong, Kaczmarek said. Another threat, he said, is model inversion, where adversaries reverse-engineer AI models to extract sensitive information, potentially compromising mission integrity. If compromised, AI systems could be used to interfere with or take control of strategically important national space missions...

The U.S. government is tightening up the integrity and security of AI systems in space. The 2023 Cyberspace Solarium Commission report stressed the importance of designating outer space as a critical infrastructure sector, urging enhanced cybersecurity protocols for satellite operators... The rivalry between the U.S. and China includes the new battleground of space. As both nations ramp up their space ambitions and militarized capabilities beyond Earth's atmosphere, the threat of cyberattacks targeting critical orbital assets has become an increasingly pressing concern... Space-based systems increasingly support critical infrastructure back on Earth, and any cyberattacks on these systems could undermine national security and economic interests.

"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."

To explain the origins of dark market, a new model of the universe has been proposed by researchers, reports Phys.org.

"Their idea is that dark matter would be produced during a infinitesimally short inflationary phase when the size of the universe quickly expanded exponentially..." Although inflation is mostly accepted by cosmologists as part of the Big Bang picture based on some evidence (though there is meaningful dissent), the driver of inflation is still unknown... [T]o-date research has not considered the possibility that a significant [amount] of dark matter could be produced during the inflationary expansion and not be diluted away. In the paper's WIFI model — Warm Inflation via ultraviolet Freeze-In — dark matter is created through small and rare interactions with particles in a hot, energetic environment. It contains a new mechanism where this production occurs just before the Big Bang, during cosmic inflation, leading to dark matter being formed much earlier than in existing theories...

"The thing that's unique to our model is that dark matter is successfully produced during inflation," said Katherine Freese, Director of the Weinberg Institute of Theoretical Physics and the Texas Center for Cosmology and Astroparticle Physics at The University of Texas at Austin and lead author of the paper. "In most [other] models, anything that is created during inflation is then 'inflated away' by the exponential expansion of the universe, to the point where there is essentially nothing left." In this new mechanism, all the dark matter that we observe today could have been created during that brief, pre-Big Bang period of inflation. The quantum field driving inflation, the inflation, loses some of its energy to radiation, and this radiation, in turn, produces dark matter particles via the freeze-in mechanism....

The WIFI [Warm Inflation via ultraviolet Freeze-In] model cannot yet be confirmed by observations. But a key part of the scenario, warm inflation, will be tested over the next decade by the so-called cosmic microwave background experiments. Confirming warm inflation would be a significant step for the WIFI model's dark matter production scenario.
"What was before inflation? Physicists have no idea."

An anonymous reader quotes a report from Space.com: NASA scientists conducting surveys of arctic ice sheets in Greenland got an unprecedented view of an abandoned "city under the ice" built by the U.S. military during the Cold War. During a scientific flight in April 2024, a NASA Gulfstream III aircraft flew over the Greenland Ice Sheet carrying radar instruments to map the depth of the ice sheet and the layers of bedrock below it. The images revealed a new view of Camp Century, a Cold War-era U.S. military base consisting of a series of tunnels carved directly into the ice sheet.

As it turns out, this abandoned "secret city" was the site of a secret Cold War project known as Project Iceworm [that] called for the construction of 2,500 miles (4,023 km) of tunnels that could be used [for] nuclear intermediate range ballistic missiles (IRBMs) at the Soviet Union. "We were looking for the bed of the ice and out pops Camp Century. We didn't know what it was at first," said NASA's Chad Greene, a cryospheric scientist at the agency's Jet Propulsion Laboratory (JPL), in an agency statement. "In the new data, individual structures in the secret city are visible in a way that they've never been seen before." "Weapons, sewage, fuel and other contaminants were buried at Camp Century when it was abandoned, but the thawing Greenland Ice Sheet threatens to unbury these dangerous relics," reports Space.com. In 2017, the U.S. government issued a statement saying it "acknowledges the reality of climate change and the risk it poses" and will "work with the Danish government and the Greenland authorities to settle questions of mutual security" over Camp Century.

Scientists are using Camp Century to serve as a warning and a signpost to measure how climate change is affecting the area. You can learn more about Camp Century in a restored declassified U.S. Army film on YouTube.

Longtime Slashdot reader AmiMoJo shares a report from Phys.org: Researchers from Imperial College London have discovered that a space-returned sample from asteroid Ryugu was rapidly colonized by terrestrial microorganisms, even under stringent contamination control measures. In the study, [...] researchers analyzed sample A0180, a tiny (1 x 0.8 mm) particle collected by the JAXA Hayabusa 2 mission from asteroid Ryugu.

Transported to Earth in a hermetically sealed chamber, the sample was opened in nitrogen in a class 10,000 clean room to prevent contamination. Individual particles were picked with sterilized tools and stored under nitrogen in airtight containers. Before analysis, the sample underwent Nano-X-ray computed tomography and was embedded in an epoxy resin block for scanning electron microscopy. Rods and filaments of organic matter, interpreted as filamentous microorganisms, were observed on the sample's surface. Variations in size and morphology of these structures resembled known terrestrial microbes. Observations showed that the abundance of these filaments changed over time, suggesting the growth and decline of a prokaryote population with a generation time of 5.2 days.

Population statistics indicate that the microorganisms originated from terrestrial contamination during the sample preparation stage rather than being indigenous to the asteroid. Results of the study determined that terrestrial biota had rapidly colonized the extraterrestrial material, even under strict contamination control. Researchers recommend enhanced contamination control procedures for future sample-return missions to prevent microbial colonization and ensure the integrity of extraterrestrial samples. Another factor in gathering contamination-free sampling is that everything used to collect extraterrestrial material originates on a planet awash in microbial life.

The FCC said it has approved a license for T-Mobile and SpaceX's Starlink to provide supplemental coverage to cover internet dead zones. Reuters reports: The license marks the first time the FCC has authorized a satellite operator collaborating with a wireless carrier to provide supplemental telecommunications coverage from space on some flexible-use spectrum bands allocated to terrestrial service. The partnership aims to extend the reach of wireless networks to remote areas and eliminate "dead zones."

T-Mobile and SpaceX announced a partnership in 2022 and in January the first set of satellites supporting the partnership was launched into low-Earth orbit with SpaceX's Falcon 9 rocket. "The FCC is actively promoting competition in the space economy by supporting more partnerships between terrestrial mobile carriers and satellite operators to deliver on a single network future that will put an end to mobile dead zones," said FCC Chair Jessica Rosenworcel.

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.

Sony is developing a new portable gaming device capable of playing PlayStation 5 games, Bloomberg News reported Monday. The project follows the 2023 release of PlayStation Portal, a streaming-only handheld, and aims to compete with Nintendo's dominant Switch console and potential Microsoft offerings in the portable gaming space.

"Scientists have found what seems to be the oldest direct evidence of hot water flowing on Mars during its ancient past," reports Space.com.

"The discovery could further indicate that the Red Planet, despite its arid and desolate appearance today, may have been capable of supporting life long ago." The evidence was delivered to Earth and sealed within the well-known Martian meteorite NWA7034, found in the Sahara Desert in 2011. Due to its black, highly polished appearance, the Martian rock is also known as "Black Beauty." At an estimated 2 billion years old, Black Beauty is the second oldest Martian meteorite ever discovered. However, the Curtin University team discovered something even older within it: a 4.45 billion-year-old zircon grain that harbors the fingerprints of fluids rich in water.

Team member Aaron Cavosie from Curtin's School of Earth and Planetary Sciences thinks this discovery will open up new avenues to understanding hydrothermal systems associated with the activity of volcanic magma that once ran through Mars. "We used nano-scale geochemistry to detect elemental evidence of hot water on Mars 4.45 billion years ago," Cavosie said in a statement. "Hydrothermal systems were essential for the development of life on Earth, and our findings suggest Mars also had water, a key ingredient for habitable environments, during the earliest history of crust formation...."

[T]his new research implies that water in liquid form may have existed on Mars even earlier than previously expected in the planet's pre-Noachian period.

Slashdot reader Bruce66423 shared this report from the Guardian: Staff have resigned at Starling Bank after its new chief executive demanded thousands of workers attend its offices more frequently, despite lacking enough space to host them.

In his first major policy change since taking over from the UK digital bank's founder, Anne Boden, in March, Raman Bhatia has ordered all hybrid staff — many of whom were in the office only one or two days a week, or on an ad-hoc basis — to travel to work for a minimum of 10 days each month. But the bank, which operates online only, admitted that some of its offices would not be equipped to handle the influx... "We are considering ways in which we can create more space," an email sent by Starling's human resources team and seen by the Guardian said.

Starling has 3,231 staff, the vast majority of whom are in the UK with some also in Dublin. However, the Guardian understands that the bank has only about 900 desks, including 260 at its Cardiff site, 320 in its London headquarters and 155 in Southampton. The bank has a further 160 desks in its newest site in Manchester, where it has signed a 10-year lease to occupy the fifth floor of the Landmark building, which also houses Santander UK and HSBC staff... Some staff have already resigned over the "rushed" announcement, while others have threatened to do so...

The return to office announcement came a month after the Financial Conduct Authority hit Starling with a £29m fine after discovering "shockingly lax" controls that it said left the financial system "wide open to criminals". That included failures in its automated screening system for individuals facing government sanctions.
Starling Bank issued this statement to explain its reasoning. "By bringing colleagues together in person, our aim is to achieve greater collaboration that will benefit our customers as we enter Starling's next phase of growth."

The article also notes that the U.K. supermarket chain Asda "has also toughened its stance, making it compulsory for thousands of workers at its offices in Leeds and Leicester to spend at least three days a week at their desks from the new year."

A team of undergraduate students from the University of Southern California's Rocket Propulsion Lab set multiple amateur spaceflight records with their rocket, Aftershock II. "The student-made missile soared 90,000 feet (27,400 meters) beyond the previous record-holder -- a rocket launched more than 20 years ago," reports Live Science. From the report: The students launched Aftershock II on Oct. 20 from a site in Black Rock Desert, Nevada. The rocket stood about 14 feet (4 meters) tall and weighed 330 pounds (150 kilograms). The rocket broke the sound barrier just two seconds after liftoff and reached its maximum speed roughly 19 seconds after launch, the RPL team wrote in a Nov. 14 paper summarizing the launch. The rocket's engine then burned out, but the craft continued to climb as atmospheric resistance decreased, enabling it to leave Earth's atmosphere 85 seconds after launch and then reach its highest elevation, or apogee, 92 seconds later. At this point, the nose cone separated from the rest of the rocket and deployed a parachute so it could safely reenter the atmosphere and touch down in the desert, where it was collected by the RPL team for analysis.

The rocket's apogee was around 470,000 feet (143,300 m) above Earth's surface, which is "further into space than any non-governmental and non-commercial group has ever flown before," USC representatives wrote in a statement. The previous record of 380,000 feet (115,800 m) was set in 2004 by the GoFast rocket made by the Civilian Space Exploration Team. During the flight, Aftershock II reached a maximum speed of around 3,600 mph (5,800 km/h), or Mach 5.5 -- five and a half times the speed of sound. This was slightly faster than GoFast, which had also held the amateur speed record for 20 years.

But elevation and speed were not the only records Aftershock II broke. "This achievement represents several engineering firsts," Ryan Kraemer, an undergraduate mechanical engineering student at USC and executive engineer of the RPL team who will soon join SpaceX's Starship team, said in the statement. "Aftershock II is distinguished by the most powerful solid-propellant motor ever fired by students and the most powerful composite case motor made by amateurs."

Apple's restrictions on mobile browsers are limiting innovation and holding back new features that could benefit iPhone users, according to provisional findings published today by the UK's Competition and Markets Authority (CMA). From a report: In its report, the CMA's independent inquiry group determined that Apple's Safari browser policies prevent competing browsers from implementing certain features, such as faster webpage loading technologies. The investigation also revealed that many UK app developers would prefer to offer progressive web apps as an alternative to App Store distribution, but Apple's current iOS limitations make this impractical.

Adding to competitive concerns, the regulator highlighted a revenue-sharing agreement between Apple and Google that "significantly reduces their financial incentives to compete" in the mobile browser space on iOS. The CMA also found that both companies can manipulate how users are presented with browser choices, making their own offerings appear as the clearest or easiest options.

An anonymous reader quotes a report from The Verge: After asking both SpaceX and Blue Origin to develop cargo landers for its Artemis missions, NASA has announced plans to use those landers to deliver heavy equipment to the Moon. The agency wants Elon Musk's SpaceX to use its Starship cargo lander to deliver a pressurized rover to the Moon "no earlier" than 2032, while Jeff Bezos' Blue Origin will be tasked with delivering a lunar surface habitat no sooner than 2033. Both launches will support NASA's Artemis missions, which aim to bring humans back to the Moon for the first time in over 50 years.

Both companies are developing human landing systems for Artemis missions -- SpaceX for Artemis III and Blue Origin for Artemis V. NASA later asked both companies to develop cargo-hauling variants of those landers, capable of carrying 26,000 to 33,000 pounds of equipment and other materials to the Moon. NASA says it will issue proposals to SpaceX and Blue Origin at the beginning of next year.

Space.com's Julian Dossett writes: For twelve years, we've watched Curiosity crawl its way over the rocky surface of Mars, decoding mysteries of the Red Planet and broadcasting back home pictures and data from the strange Martian environment. The Mars rover, built by NASA's Jet Propulsion Laboratory (JPL), has slowly scaled Mount Sharp since 2014. This mountain, officially monikered "Aeolis Mons," was discovered in the 1970s; cut into its alien landscape is the boulder-packed Gediz Vallis channel, which some scientists believe to be an ancient river bed.

Curiosity crossed into Gediz Vallis earlier this year -- and, yesterday, JPL released a real treat for Mars lovers: a 360-degree panorama view of the Gediz Vallis channel. You can play the YouTube video and move your phone around for the nifty interactive feature. Or, if you're using a desktop PC, you can shift the video around with a mouse. The panorama showcases features like Kukenan Butte and Gale Crater Rim, with scientists debating whether water, wind, or landslides shaped the boulder-laden terrain. Another interesting observation is the presence of mysterious sulfur stones with yellow crystals. Scientists are unsure about their origin since such formations on Earth are linked to hot springs and volcanoes -- neither of which are known to exist on Mars.

Curiosity is now heading toward a location called "the boxwork," a mineral-rich area potentially formed by ancient water flows.

An anonymous reader quotes a report from 404 Media: Instagram is flooded with hundreds of AI-generated influencers who are stealing videos from real models and adult content creators, giving them AI-generated faces, and monetizing their bodies with links to dating sites, Patreon, OnlyFans competitors, and various AI apps. The practice, first reported by 404 Media in April, has since exploded in popularity, showing that Instagram is unable or unwilling to stop the flood of AI-generated content on its platform and protect the human creators on Instagram who say they are now competing with AI content in a way that is impacting their ability to make a living.

According to our review of more than 1,000 AI-generated Instagram accounts, Discord channels where the people who make this content share tips and discuss strategy, and several guides that explain how to make money by "AI pimping," it is now trivially easy to make these accounts and monetize them using an assortment of off-the-shelf AI tools and apps. Some of these apps are hosted on the Apple App and Google Play Stores. Our investigation shows that what was once a niche problem on the platform has industrialized in scale, and it shows what social media may become in the near future: a space where AI-generated content eclipses that of humans. [...]

Out of more than 1,000 AI-generated Instagram influencer accounts we reviewed, 100 included at least some deepfake content which took existing videos, usually from models and adult entertainment performers, and replaced their face with an AI-generated face to make those videos seem like new, original content consistent with the other AI-generated images and videos shared by the AI-generated influencer. The other 900 accounts shared images that in some cases were trained on real photographs and in some cases made to look like celebrities, but were entirely AI-generated, not edited photographs or videos. Out of those 100 accounts that shared deepfake or face-swapped videos, 60 self-identify as being AI-generated, writing in their bios that they are a "virtual model & influencer" or stating "all photos crafted with AI and apps." The other 40 do not include any disclaimer stating that they are AI-generated. Adult content creators like Elaina St James say they're now directly competing with these AI rip-off accounts that often use stolen content. Since the explosion of AI-generated influencer accounts on Instagram, St James said her "reach went down tremendously," from a typical 1 million to 5 million views a month to not surpassing a million in the last 10 months, and sometimes coming in under 500,000 views. While she said changes to Instagram's algorithm could also be at play, these AI-generated influencer accounts are "probably one of the reasons my views are going down," St James told 404 Media. "It's because I'm competing with something that's unnatural."

Alexios Mantzarlis, the director of the security, trust, and safety initiative at Cornell Tech and formerly principal of trust and safety intelligence at Google, started researching the problem to see where AI-generated content is taking social media and the internet. "It felt like a possible sign of what social media is going to look like in five years," said Mantzarlis. "Because this may be coming to other parts of the internet, not just the attractive-people niche on Instagram. This is probably a sign that it's going to be pretty bad."

A new study reveals that many users, particularly students and Redditors, view Z-Library as a vital resource for overcoming economic barriers to education, reflecting a "Robin Hood" mentality that prioritizes access to knowledge over copyright concerns. TorrentFreak reports: The research looks at the motivations of two groups; Reddit users and Chinese postgraduate students. Despite the vast differences between these groups, their views on Z-Library are quite similar. The 134 Reddit responses were sampled from the Zlibrary subreddit, which is obviously biased in favor of the site. However, the reasoning goes well beyond a simple "I want free stuff" arguments. Many commenters highlighted that they were drawn to the site out of poverty, for example, or they highlighted that Z-Library was an essential tool to fulfill their academic goals.

"Living in a 3rd world country, 1 book would cost like 50%- 80% already of my daily wage," one Redditor wrote. The idea that Z-Library is a 'necessary evil' was also highlighted by other commenters. This includes a student who can barely make ends meet, and a homeless person, who has neither the money nor the space for physical books. The lack of free access to all study materials, including academic journal subscriptions at university libraries, was also a key motivator. Paired with the notion that journal publishers make billions of dollars, without compensating authors, justification is found for 'pirate' alternatives. "They make massive profits. So stealing from them doesn't hurt the authors nor reviewers, just the rich greedy publishers who make millions just to design a cover and click 'publish'," one Redditor wrote.

The second part of the study is conducted in a more structured format among 103 postgraduate students in China. This group joined a seminar where Z-Library and the crackdown were discussed. In addition, the students participated in follow-up focus group discussions, while also completing a survey. Despite not all being users of the shadow library, 41% of the students agreed that the site's (temporary) shutdown affected their ability to study and find resources for degree learning. In general, the students have a favorable view toward Z-Library and similar sites, and 71% admit that they have used a shadow library in the past. In line with China's socialist values, the overwhelming majority of the students agreed that access to knowledge should be free for everyone. While the students are aware of copyright law, they believe that the need to access knowledge outweighs rightsholders' concerns. This is also reflected in the following responses, among others. All in all, Z-Library and other shadow libraries are seen as a viable option for expensive or inaccessible books, despite potential copyright concerns. The paper has been published in the Journal of University Teaching & Learning Practice.

SpaceX's Starship rocket successfully completed its sixth launch today. Not only did it carry the first-ever payload but it also briefly re-lit one of its six Raptor engines about 38 minutes into flight, a crucial milestone for future space missions. Space Magazine reports: SpaceX landed Starship's huge first-stage booster, known as Super Heavy, back at the launch tower on the vehicle's most recent flight, which occurred on Oct. 13. The company aimed to repeat that feat -- which the tower achieved with its "chopstick" arms -- today, but the flight data didn't support an attempt. "We tripped a commit criteria," SpaceX's Dan Huot said during the company's Flight 6 webcast. So Super Heavy ended up coming down for a controlled splashdown in the Gulf of Mexico instead, hitting the waves seven minutes after liftoff.

Today's mission aimed to do far more than just bring Super Heavy back to Earth in one piece. SpaceX also wanted to put Starship's upper stage -- a 165-foot-tall (50 m) spacecraft called Starship, or simply "Ship" -- through its paces. The launch sent Ship on the same semi-orbital trajectory that it took on Flight 5, targeting a splashdown in the Indian Ocean off the northwestern coast of Australia about 65 minutes after liftoff. But Ship also achieved some new milestones along the way this time. For example, Flight 6 carried the first-ever Starship payload -- a plush banana onboard Ship, which served as a zero-gravity indicator. (It was not deployed into space.) In addition, Ship briefly re-lit one of its six Raptor engines about 38 minutes into the flight. (Super Heavy also employs Raptors -- a whopping 33 of them.)

This burn helped show that Ship can perform the maneuvers needed to come back to Earth safely during orbital missions. Indeed, Ship is designed to be fully and rapidly reusable, just like Super Heavy; SpaceX eventually intends to catch it with the chopstick arms as well, and will likely try to do so on a test flight in the near future.

India plans to build a moon-orbiting space station by 2040 that will support crewed missions to the moon and serve as a hub for scientific research. Space Magazine reports: If all goes according to plan, the lunar space station will be completed around the same time the nation's astronauts land on the moon, with construction of a permanent base on the surface before 2050. The lunar space station appears to be the third and final phase of India's moon exploration efforts. [...]

The lunar space station may be similar to the one India plans to build in Earth orbit, known as the Bharatiya Antariksh Station, or BAS. The development of this station's first module, BAS-1, was greenlit by the Indian government in September. Officials have said the first module will be launched to low Earth orbit by 2028, and the entire station will be operational by 2035.
