"Astronomers have spotted a quasi-moon near Earth," reports CNN, "and the small space rock has likely been hanging out near our planet unseen by telescopes for about 60 years, according to new research." The newly discovered celestial object, named 2025 PN7, is a type of near-Earth asteroid that orbits the sun but sticks close to our planet. Like our world, 2025 PN7 takes one year to complete an orbit around the sun... The newly found 2025 PN7 is just one of a handful of known quasi-moons with orbits near our planet, including Kamo'oalewa, which is also thought to be an ancient lunar fragment. Kamo'oalewa is one of the destinations of China's Tianwen-2 mission launched in May, which aims to collect and return samples from the space rock in 2027. The Pan-STARRS observatory located on the Haleakala volcano in Hawaii captured observations of 2025 PN7 on August 29. Archival data revealed that the object has been in an Earth-like orbit for decades. The quasi-moon managed to escape the notice of astronomers for so long because it is small and faint, said Carlos de la Fuente Marcos, a researcher on the faculty of mathematical sciences at the Complutense University of Madrid who recently authored a paper about the space rock. The paper was published on September 2 in the journal Research Notes of the American Astronomical Society, which is for timely non-peer-reviewed astronomical observations. The space rock swings within 186,000 miles (299,337 kilometers) of us during its closest pass of our planet, de la Fuente Marcos said.... "It can only be detected by currently available telescopes when it gets close to our planet as it did this summer," de la Fuente Marcos explained. "Its visibility windows are few and far between. It is a challenging object...." Astronomers are still trying to figure out 2025 PN7's size. About 98 feet (30 meters) across is a reasonable estimate, de la Fuente Marcos said. It also has the potential to be 62 feet (19 meters) in diameter, according to EarthSky. The space rock is currently the smallest-known quasi-moon to have orbited near Earth, de la Fuente Marcos said.

Long-time Slashdot reader theodp writes: Over at the Communications of the ACM, Bard College CS Prof Valerie Barr explains why she's Feeling Cranky About AI and CS Education. Having seen CS education go through a number of we-have-to-teach-this moments over the decades — introductory programming languages, the Web, Data Science, etc. — Barr turns her attention to the next hand-wringing "what will we do" CS education moment with AI. "We're jumping through hoops without stopping first to question the run-away train," Barr writes... Barr calls for stepping back from "the industry assertion that the ship has sailed, every student needs to use AI early and often, and there is no future application that isn't going to use AI in some way" and instead thoughtfully "articulate what sort of future problem solvers and software developers we want to graduate from our programs, and determine ways in which the incorporation of AI can help us get there." From the article: In much discussion about CS education: a.) There's little interest in interrogating the downsides of generative AI, such as the environmental impact, the data theft impact, the treatment and exploitation of data workers. b.) There's little interest in considering the extent to which, by incorporating generative AI into our teaching, we end up supporting a handful of companies that are burning billions in a vain attempt to each achieve performance that is a scintilla better than everyone else's. c.) There's little interest in thinking about what's going to happen when the LLM companies decide that they have plateaued, that there's no more money to burn/spend, and a bunch of them fold—but we've perturbed education to such an extent that our students can no longer function without their AI helpers.

Optus was unaware network changes caused a problem, and ignored some customer complaints

Australian telco Optus says its staff may not have followed established processes when a firewall upgrade they conducted resulted in customers not being able to call emergency emergency services for fourteen hours – a period during which it is thought three of the carrier’s customers died after trying to seek help, according to the company's CEO.…

"On a recent assignment to test defenses, Dave Brauchler of the cybersecurity company NCC Group tricked a client's AI program-writing assistant into executing programs that forked over the company's databases and code repositories," reports the Washington Post. "We have never been this foolish with security," Brauchler said... Demonstrations at last month's Black Hat security conference in Las Vegas included other attention-getting means of exploiting artificial intelligence. In one, an imagined attacker sent documents by email with hidden instructions aimed at ChatGPT or competitors. If a user asked for a summary or one was made automatically, the program would execute the instructions, even finding digital passwords and sending them out of the network. A similar attack on Google's Gemini didn't even need an attachment, just an email with hidden directives. The AI summary falsely told the target an account had been compromised and that they should call the attacker's number, mimicking successful phishing scams. The threats become more concerning with the rise of agentic AI, which empowers browsers and other tools to conduct transactions and make other decisions without human oversight. Already, security company Guardio has tricked the agentic Comet browser addition from Perplexity into buying a watch from a fake online store and to follow instructions from a fake banking email... Advanced AI programs also are beginning to be used to find previously undiscovered security flaws, the so-called zero-days that hackers highly prize and exploit to gain entry into software that is configured correctly and fully updated with security patches. Seven teams of hackers that developed autonomous "cyber reasoning systems" for a contest held last month by the Pentagon's Defense Advanced Research Projects Agency were able to find a total of 18 zero-days in 54 million lines of open source code. They worked to patch those vulnerabilities, but officials said hackers around the world are developing similar efforts to locate and exploit them. Some longtime security defenders are predicting a once-in-a-lifetime, worldwide mad dash to use the technology to find new flaws and exploit them, leaving back doors in place that they can return to at leisure. The real nightmare scenario is when these worlds collide, and an attacker's AI finds a way in and then starts communicating with the victim's AI, working in partnership — "having the bad guy AI collaborate with the good guy AI," as SentinelOne's [threat researcher Alex] Delamotte put it. "Next year," said Adam Meyers, senior vice president at CrowdStrike, "AI will be the new insider threat." In August more than 1,000 people lost data to a modified Nx program (downloaded hundreds of thousands of times) that used pre-installed coding tools from Google/Anthropic/etc. According to the article, the malware "instructed those programs to root out" sensitive data (including passwords or cryptocurrency wallets) and send it back to the attacker. "The more autonomy and access to production environments such tools have, the more havoc they can wreak," the article points out — including this quote from SentinelOne threat researcher Alex Delamotte. "It's kind of unfair that we're having AI pushed on us in every single product when it introduces new risks."

Long-time Slashdot reader fahrbot-bot shared this report from ZME Science Researchers from the University of Turku, in collaboration with Aalto University and Wageningen University, have developed a bio-based UV protection film for solar cells that not only blocks nearly all harmful ultraviolet light but also outperforms commercial plastic films. The key ingredient is a water extract made from red onion skins... [T]he same sunlight that powers [solar cells] can also degrade their delicate components — particularly the electrolyte inside dye-sensitized solar cells (DSSCs), a type known for their flexibility and low-light performance. To mitigate this, manufacturers typically wrap cells in UV-protective films made from petroleum-based plastics like polyethylene terephthalate (PET). But these plastics degrade over time and are difficult to recycle... Nanocellulose can be processed into thin, transparent films that serve as the perfect substrate for UV-blocking compounds. Their breakthrough came when they dyed these films using an extract from red onion skins, a common kitchen waste. The result was a filter that blocked 99.9% of UV radiation up to 400 nanometers, a feat that outstripped even the PET-based commercial filters chosen for comparison... [T]he onion-treated filter excelled: it let through over 80% of light in the 650-1,100 nm range — an ideal sweet spot for energy absorption... Even predictive modeling based on early degradation trends suggested the CNF-ROE filter could extend a solar cell's lifetime to roughly 8,500 hours. The PET-based filter? Just 1,500 hours... [T]he red onion extract offered a rare combination of longevity, transparency, and sustainability... The team envisions biodegradable solar cells for smart packaging, remote sensors, or wearable devices — especially in applications where recovery and recycling are not feasible. Their work is part of the BioEST project, funded by the Research Council of Finland, which supports sustainable innovation across electronics and materials science. This achievement taps into a broader movement to decarbonize every step of solar energy production. Plastic packaging is one of the overlooked sources of emissions in clean technology. Swapping out fossil-based plastics for biodegradable alternatives helps close that loop... The findings appeared in the journal Applied Optical Materials.

In a debate on employment rights, a U.K. Parliament member brought up Meta's former director of global public policy Sarah Wynn-Williams Louise Haigh, the former Labour transport secretary, said Wynn-Williams was facing a fine of $50,000 (£37,000) every time she breached an order secured by Meta preventing her from talking disparagingly about the company... "I am sure that the whole house and the government will stand with Sarah as we pass this legislation to ensure that whistleblowers and those with the moral courage to speak out are always protected...." Meta has emphasised that Wynn-Williams entered into the non-disparagement agreement voluntarily as part of her departure. Meta said that to date, Wynn-Williams had not been forced to make any payments under the agreement... [The ruling came after Wynn-Williams published an exposé in March about her time at Facebook titled Careless People: A Cautionary Tale of Power, Greed, and Lost Idealism.] The ruling stated Wynn-Williams should stop promoting the book and, to the extent she could, stop further publication... Wynn-Williams has not spoken in public since appearing at the Senate hearing in April. Wynn-Williams "remains silenced" according to her lawyer, who tells the Guardian that Meta's arbitration proceedings in the U.K. "threaten to bankrupt" the whistleblower.

A July combat training exercise involved a satellite dish-style antenna that "could fire enough electromagnetic energy to fry the satellite 22,000 miles away," reports the Washington Post. But "Instead, the salvo would be more covert — millisecond pulses of energy that would subtly disrupt the satellite's signals, which U.S. military forces were using to communicate in the Pacific Ocean." The goal was to disguise the strike as a garbled connection that could be easily remedied by securing a loose cable or a simple reboot, leaving U.S. service members frustrated without raising their suspicions. [And using less power "would make it harder for the Blue Team to track where the interference was coming from."] This is how the next war could start: invisible shots fired in space on the electromagnetic spectrum that could render U.S. fighter jets and aircraft carriers deaf and blind, unable to communicate. In this case, the "aggressors" targeting the U.S. satellite were not from China or Russia, but rather an elite squadron of U.S. Space Force Guardians mimicking how potential adversaries would act in a conflict that begins in orbit... Involving more than 700 service members and spanning 50 million square miles and six time zones, the training exercise, called Resolute Space, was observed firsthand exclusively by The Washington Post. The article describes leadership at the U.S. Space Force "still honing their mission while jousting with adversaries, such as China, that are moving quickly and conducting combat-like operations in orbit... While the Space Force continues to evolve, many defense analysts and some members of Congress fear the United States has already ceded its dominance in space to China and others." With a budget of just $40 billion, the relatively tiny Space Force makes up just about 4 percent of the Defense Department's budget and less than 1 percent of its personnel. It has more than 15,000 Guardians, which also includes several thousand civilians. By comparison, the Army has nearly 1 million soldiers. The Space Force has been squeezed under the department of the Air Force and struggled to distinguish itself from the other branches... China, Russia and others have demonstrated that they can take out or interfere with the satellites operated by the Pentagon and intelligence agencies that provide the nation's missile warning and tracking, reconnaissance and communications. China in particular has moved rapidly to build an arsenal of space-based weapons... [R]ecently, several of China's satellites have engaged in what Space Force officials have called "dogfighting," jousting with U.S. satellites at high speeds and close ranges.

Last week the Guardian reported on "thousands of AI workers contracted for Google through Japanese conglomerate Hitachi's GlobalLogic to rate and moderate the output of Google's AI products, including its flagship chatbot Gemini... and its summaries of search results, AI Overviews." "AI isn't magic; it's a pyramid scheme of human labor," said Adio Dinika, a researcher at the Distributed AI Research Institute based in Bremen, Germany. "These raters are the middle rung: invisible, essential and expendable...." Ten of Google's AI trainers the Guardian spoke to said they have grown disillusioned with their jobs because they work in siloes, face tighter and tighter deadlines, and feel they are putting out a product that's not safe for users... In May 2023, a contract worker for Appen submitted a letter to the US Congress that the pace imposed on him and others would make Google Bard, Gemini's predecessor, a "faulty" and "dangerous" product This week Google laid off 200 of those moderating contractors, reports Wired. "These workers, who often are hired because of their specialist knowledge, had to have either a master's or a PhD to join the super rater program, and typically include writers, teachers, and people from creative fields." Workers still at the company claim they are increasingly concerned that they are being set up to replace themselves. According to internal documents viewed by WIRED, GlobalLogic seems to be using these human raters to train the Google AI system that could automatically rate the responses, with the aim of replacing them with AI. At the same time, the company is also finding ways to get rid of current employees as it continues to hire new workers. In July, GlobalLogic made it mandatory for its workers in Austin, Texas, to return to office, according to a notice seen by WIRED... Some contractors attempted to unionize earlier this year but claim those efforts were quashed. Now they allege that the company has retaliated against them. Two workers have filed a complaint with the National Labor Relations Board, alleging they were unfairly fired, one due to bringing up wage transparency issues, and the other for advocating for himself and his coworkers. "These individuals are employees of GlobalLogic or their subcontractors, not Alphabet," Courtenay Mencini, a Google spokesperson, said in a statement... "Globally, other AI contract workers are fighting back and organizing for better treatment and pay," the article points out, noting that content moderators from around the world facing similar issues formed the Global Trade Union Alliance of Content Moderators which includes workers from Kenya, Turkey, and Colombia.
