Is Russia Developing an Anti-Satellite Weapon to Target Starlink?
science - Posted On:2025-12-27 16:45:01 Source: slashdot
An anonymous reader shared this report from the Associated Press: Two NATO-nation intelligence services suspect Russia is developing a new anti-satellite weapon to target Elon Musk's Starlink constellation with destructive orbiting clouds of shrapnel, with the aim of reining in Western space superiority that has helped Ukraine on the battlefield. Intelligence findings seen by The Associated Press say the so-called "zone-effect" weapon would seek to flood Starlink orbits with hundreds of thousands of high-density pellets, potentially disabling multiple satellites at once but also risking catastrophic collateral damage to other orbiting systems. Analysts who haven't seen the findings say they doubt such a weapon could work without causing uncontrollable chaos in space for companies and countries, including Russia and its ally China, that rely on thousands of orbiting satellites for communications, defense and other vital needs. Such repercussions, including risks to its own space systems, could steer Moscow away from deploying or using such a weapon, analysts said. "I don't buy it. Like, I really don't," said Victoria Samson, a space-security specialist at the Secure World Foundation who leads the Colorado-based nongovernmental organization's annual study of anti-satellite systems. "I would be very surprised, frankly, if they were to do something like that." [Later they suggested the research might just be experimental.] But the commander of the Canadian military's Space Division, Brig. Gen. Christopher Horner, said such Russian work cannot be ruled out in light of previous U.S. allegations that Russia also has been pursuing an indiscriminate nuclear, space-based weapon. "I can't say I've been briefed on that type of system. But it's not implausible," he said... The French military's Space Command said in a statement to the AP that it could not comment on the findings but said, "We can inform you that Russia has, in recent years, been multiplying irresponsible, dangerous, and even hostile actions in space." The article also points out that this month Russia "said it has fielded a new ground-based missile system, the S-500, which is capable of hitting low-orbit targets..."

Should Physicists Study the Question: What is Life?
science - Posted On:2025-12-27 11:45:00 Source: slashdot
An astrophysicist at the University of Rochester writes that "many" of his colleagues in physics "have come to believe that a mystery is unfolding in every microbe, animal, and human." And it's a mystery that: - "Challenges basic assumptions physicists have held for centuries" - "May even help redefine the field for the next generation" - "Could answer essential questions about AI." In short, while physicists have favored a "reductionist" philosophy about the fundamental laws controlling the universe (energy, mattery, space, and time), "long-promised 'theories of everything' such as string theory, have not borne significant fruit: There are, however, ways other than reductionism to think about what's fundamental in the universe. Beginning in the 1980s, physicists (along with researchers in other fields) began developing new mathematical tools to study what's called "complexity" — systems in which the whole is far more than the sum of its parts. The end goal of reductionism was to explain everything in the universe as the result of particles and their interactions. Complexity, by contrast, recognizes that once lots of particles come together to produce macroscopic things — such as organisms — knowing everything about particles isn't enough to understand reality... Physicists have always been good at capturing the essential aspects of a system and casting those essentials in the language of mathematics... Now those skills must be brought to bear on an age-old question that is only just getting its proper due: What is life? Using these skills, physicists — working together with representatives of all the other disciplines that make up complexity science — may crack open the question of how life formed on Earth billions of years ago and how it might have formed on the distant alien worlds we can now explore with cutting-edge telescopes. Just as important, understanding why life, as an organized system, is different at a fundamental level from all the other stuff in the universe may help astronomers design new strategies for finding it in places bearing little resemblance to Earth. Analyzing life — no matter how alien — as a self-organizing information-driven system may provide the key to detecting biosignatures on planets hundreds of light-years away. Closer to home, studying the nature of life is likely essential to fully understanding intelligence — and building artificial versions. Throughout the current AI boom, researchers and philosophers have debated whether and when large language models might achieve general intelligence or even become conscious — or whether, in fact, some already have. The only way to properly assess such claims is to study, by any means possible, the sole agreed-upon source of general intelligence: life. Bringing the new physics of life to problems of AI may not only help researchers predict what software engineers can build; it may also reveal the limits of trying to capture life's essential character in silicon.

Rocket Crashes in Brazil's First Commercial Launch
science - Posted On:2025-12-27 10:00:00 Source: slashdot
The first-ever commercial rocket launched at Brazil's Alcantara Space Center crashed soon after liftoff late earlier this week, dealing a blow to Brazilian aerospace ambitions and shares of South Korean satellite launch company Innospace. From a report: The rocket began its vertical trajectory as planned after liftoff [Monday] at 10:13 p.m. local time (0113 GMT) but fell to the ground after something went wrong 30 seconds into its flight, Innospace CEO Kim Soo-jong said in a letter to shareholders. The craft crashed within a pre-designated safety zone and did not harm anyone, he said. Brazil's air force said firefighters were sent to analyze the wreckage and impact zone. "We are deeply sorry that we failed to meet the expectations of our shareholders who supported our first commercial launch," the CEO wrote in the letter, which was posted on the company's website on December 23. Innospace shares plunged nearly 29% in Seoul in its biggest daily drop and heaviest daily trading volume since its July 2024 listing. Read more of this story at Slashdot.
NASA Will Soon Find Out If the Perseverance Rover Can Really Persevere On Mars
science - Posted On:2025-12-25 02:15:00 Source: slashdot
With NASA's Mars Sample Return mission delayed into the 2030s, engineers are certifying the Perseverance rover to keep operating for many more years while it continues collecting and safeguarding Martian rock samples. Ars Technica reports: The good news is that the robot, about the size of a small SUV, is in excellent health, according to Steve Lee, Perseverance's deputy project manager at NASA's Jet Propulsion Laboratory (JPL). "Perseverance is approaching five years of exploration on Mars," Lee said in a press briefing Wednesday at the American Geophysical Union's annual fall meeting. "Perseverance is really in excellent shape. All the systems onboard are operational and performing very, very well. All the redundant systems onboard are available still, and the rover is capable of supporting this mission for many, many years to come." The rover's operators at JPL are counting on sustaining Perseverance's good health. The rover's six wheels have carried it a distance of about 25 miles, or 40 kilometers, since landing inside the 28-mile-wide (45-kilometer) Jezero Crater in February 2021. That is double the original certification for the rover's mobility system and farther than any vehicle has traveled on the surface of another world. Now, engineers are asking Perseverance to perform well beyond expectations. An evaluation of the rover's health concluded it can operate until at least 2031. The rover uses a radioactive plutonium power source, so it's not in danger of running out of electricity or fuel any time soon. The Curiosity rover, which uses a similar design, has surpassed 13 years of operations on Mars. There are two systems that are most likely to limit the rover's useful lifetime. One is the robotic arm, which is necessary to collect samples, and the other is the rover's six wheels and the drive train that powers them. "To make sure we can continue operations and continue driving for a long, long way, up to 100 kilometers (62 miles), we are doing some additional testing," Lee said. "We've successfully completed a rotary actuator life test that has now certified the rotary system to 100 kilometers for driving, and we have similar testing going on for the brakes. That is going well, and we should finish those early part of next year." Read more of this story at Slashdot.
Russia Plans a Nuclear Power Plant on the Moon Within a Decade
science - Posted On:2025-12-24 14:15:01 Source: slashdot
Russia plans to put a nuclear power plant on the moon in the next decade to supply its lunar space programme and a joint Russian-Chinese research station, as major powers rush to explore the earth's only natural satellite. Reuters: Ever since Soviet cosmonaut Yuri Gagarin became the first human to go into space in 1961, Russia has prided itself as a leading power in space exploration, but in recent decades it has fallen behind the United States and, increasingly, China. Russia's ambitions suffered a massive blow in August 2023 when its unmanned Luna-25 mission smashed into the surface of the moon while attempting to land, and Elon Musk has revolutionised the launch of space vehicles - once a Russian speciality. Russia's state space corporation, Roscosmos, said in a statement that it planned to build a lunar power plant by 2036 and signed a contract with the Lavochkin Association aerospace company to do it. Roscosmos did not say explicitly that the plant would be nuclear but it said the participants included Russian state nuclear corporation Rosatom and the Kurchatov Institute, Russia's leading nuclear research institute. Roscosmos said the purpose of the plant was to power Russia's lunar programme, including rovers, an observatory and the infrastructure of the joint Russian-Chinese International Lunar Research Station.

Being Santa Claus is a year-round calling
Science - Posted On:2025-12-24 12:15:00 Source: arstechnica
Tis the season when professional Santas are in peak demand, but many who choose this line of work often view it as a higher calling and maintain some aspects of the identity all year round—even those who don't fit the stereotypical popular image of Santa, according to a paper published in the Academy of Management Journal.
Co-author Christina Hymer of the University of Tennessee got the idea for the study during the COVID pandemic, when she spent a lot of time watching Christmas movies with her toddler. One favorite was 2003's Elf, starring Will Farrell as a full-sized human raised among elves who goes to New York City to find his biological father. The film prompted her to wonder about why someone would want to be Santa Claus and what their experiences in that role would be.
Hymer and her co-authors partnered with the leader of a "Santa school" to analyze archival surveys of 849 professional Santas, and conducted a new survey of another 382 Santas. They also did over 50 personal interviews with professional Santas. (One subject showed up in full costume for his zoom interview, with a North Pole background, and signed off with a merry "ho! ho! ho!")
2015 Radio Interview Frames AI As 'High-Level Algebra'
science - Posted On:2025-12-24 05:15:00 Source: slashdot
Longtime Slashdot reader MrFreak shares a public radio interview from 2015 discussing artificial intelligence as inference over abstract inputs, along with scaling limits, automation, and governance models, where for-profit engines are constrained by nonprofit oversight: Recorded months before OpenAI was founded, the conversation treats intelligence as math plus incentives rather than something mystical, touching on architectural bottlenecks, why "reasoning" may not simply emerge from brute force, labor displacement, and institutional design for advanced AI systems. Many of the themes align closely with current debates around large language models and AI governance. The recording was revisited following recent remarks by Sergey Brin at Stanford, where he acknowledged that despite Google's early work on Transformers, institutional hesitation and incentive structures limited how aggressively the technology was pursued. The interview provides an earlier, first-principles perspective on how abstraction, scaling, and organizational design might interact once AI systems begin to compound.

China just carried out its second reusable launch attempt in three weeks
Science - Posted On:2025-12-23 17:45:00 Source: arstechnica
For the second time this month, a Chinese rocket designed for reuse successfully soared into low-Earth orbit on its first flight Monday, defying the questionable odds that burden the debuts of new launch vehicles.
The first Long March 12A rocket, roughly the same height and diameter of SpaceX's workhorse Falcon 9, lifted off from the Jiuquan Satellite Launch Center at 9:00 pm EST Monday (02:00 UTC Tuesday).
Less than 10 minutes later, rocket's methane-fueled first stage booster hurtled through the atmosphere at supersonic speed, impacting in a remote region about 200 miles downrange from the Jiuquan spaceport in northwestern China. The booster failed to complete a braking burn to slow down for landing at a prepared location near the edge of the Gobi Desert.
Safety Panel Says NASA Should Have Taken Starliner Incident More Seriously
science - Posted On:2025-12-23 05:15:00 Source: slashdot
joshuark shares a report from Ars Technica: For the better part of two months last year, most of us had no idea how serious the problems were with Boeing's Starliner spacecraft docked at the International Space Station. A safety advisory panel found this uncertainty also filtered through NASA's workforce. [...] The Starliner capsule was beset by problems with its maneuvering thrusters and pernicious helium leaks on its 27-hour trip from the launch pad to the ISS. For a short time, Starliner commander Wilmore lost his ability to control the movements of his spacecraft as it moved in for docking at the station in June 2024. Engineers determined that some of the thrusters were overheating and eventually recovered most of their function, allowing Starliner to dock with the ISS. [...] Throughout that summer, managers from NASA and Boeing repeatedly stated that the spacecraft was safe to bring Wilmore and Williams home if the station needed to be evacuated in an emergency. But officials on the ground ordered extensive testing to understand the root of the problems. Buried behind the headlines, there was a real chance NASA managers would decide -- as they ultimately did -- not to put astronauts on Boeing's crew capsule when it was time to depart the ISS. [...] It would have been better, [Charlie Precourt, a former space shuttle commander and now a member of NASA's Aerospace Safety Advisory Panel (ASAP)] and other panel members said Friday, if NASA made a formal declaration of an in-flight "mishap" or "high visibility close call" soon after the Starliner spacecraft's troubled rendezvous with the ISS. Such a declaration would have elevated responsibility for the investigation to NASA's safety office. [...] After months of testing and analysis, NASA officials were unsure if the thruster problems would recur on Starliner's flight home. They decided in August 2024 to return the spacecraft to the ground without the astronauts, and the capsule safely landed in New Mexico the following month. The next Starliner flight will carry only cargo to the ISS. The safety panel recommended that NASA review its criteria and processes to ensure the language is "unambiguous" in requiring the agency to declare an in-flight mishap or a high-visibility close call for any event involving NASA personnel "that leads to an impact on crew or spacecraft safety."

How a Power Outage In Colorado Caused US Official Time To Be 4.8 Microseconds
science - Posted On:2025-12-23 02:15:00 Source: slashdot
Tony Isaac shares a report from NPR: The U.S. government calculates the country's official time using more than a dozen atomic clocks at a federal facility northwest of Denver. But when a destructive windstorm knocked out power to the National Institute of Standards and Technology (NIST) laboratory in Boulder on Wednesday and a backup generator subsequently failed, time ever so slightly slowed down. The lapse "resulted in NIST UTC [universal coordinated time] being 4.8 microseconds slower than it should have been," NIST spokesperson Rebecca Jacobson said in an email. [...] Since 2007, the official time of the U.S. has been determined by the commerce secretary, who oversees NIST, along with the U.S. Navy. The national time standard is known as NIST UTC. (Somewhat confusingly, UTC itself is a separate, global time standard to which the U.S. and other countries contribute measurements.) NIST currently calculates the standard using a weighted average of the readings of 16 atomic clocks situated across the Boulder campus. Atomic clocks, including hydrogen masers and cesium beam clocks, rely on the natural resonant frequencies of atoms to tell time with extremely high accuracy. All of the atomic clocks continued ticking through the power outage last week thanks to their battery backup systems, according to NIST supervisory research physicist Jeff Sherman. What failed was the connection between some of the clocks and NIST's measurement and distribution systems, he said. Some critical operations staff who were still on site following the severe weather were able to restore backup power by activating a diesel generator the team had kept in reserve, Sherman said.

In a surprise announcement, Tory Bruno is out as CEO of United Launch Alliance
Science - Posted On:2025-12-22 22:45:00 Source: arstechnica
Tory Bruno, a veteran engineer and aerospace industry executive, has resigned from the top job at United Launch Alliance after more than a decade competing against the growing dominance of SpaceX, the company announced Monday.
The news of Bruno's sudden resignation was unexpected. His tenure was marked by a decline in ULA's market share as rival SpaceX competed for and won ever-larger US government launch contracts. More recently, Bruno oversaw the successful debut of ULA's Vulcan rocket, followed by struggles to ramp up the new rocket's launch cadence.
Bruno had a 30-year career as an engineer and general manager for Lockheed Martin's ballistic missile programs before taking over as president and CEO of United Launch Alliance in August 2014. He arrived as SpaceX started making inroads with its partially reusable Falcon 9 rocket, and ULA's leading position in the US launch market looked to be in doubt.
James Webb Space Telescope Confirms 1st 'Runaway' Supermassive Black Hole
science - Posted On:2025-12-20 02:15:00 Source: slashdot
Longtime Slashdot reader schwit1 shares a report from Space.com: Astronomers have made a truly mind-boggling discovery using the James Webb Space Telescope (JWST): a runaway black hole 10 million times larger than the sun, rocketing through space at a staggering 2.2 million miles per hour (1,000 kilometers per second). That not only makes this the first confirmed runaway supermassive black hole, but this object is also one of the fastest-moving bodies ever detected, rocketing through its home, a pair of galaxies named the "Cosmic Owl," at 3,000 times the speed of sound at sea level here on Earth. If that isn't astounding enough, the black hole is pushing forward a literal galaxy-sized "bow-shock" of matter in front of it, while simultaneously dragging a 200,000 light-year-long tail behind it, within which gas is accumulating and triggering star formation. "It boggles the mind!" discovery team leader Pieter van Dokkum of Yale University told Space.com. "The forces that are needed to dislodge such a massive black hole from its home are enormous. And yet, it was predicted that such escapes should occur!" "This is the only black hole that has been found far away from its former home," van Dokkum said. "That made it the best candidate [for a] runaway supermassive black hole, but what was missing was confirmation. All we really had was a streak that was difficult to explain in any other way. With the JWST, we have now confirmed that there is indeed a black hole at the tip of the streak, and that it is speeding away from its former host." The research is currently available as a pre-peer-reviewed paper on arXiv. Read more of this story at Slashdot.
The evolution of expendability: Why some ants traded armor for numbers
Science - Posted On:2025-12-19 17:30:00 Source: arstechnica
The trade-off between quality and quantity is a fundamental economic dilemma. Now, a team of British, American, and Japanese researchers describes how it applies to biology, as well. They have discovered that this dilemma most likely shaped the evolutionary trajectory of ants, one of Earth’s most successful groups of organisms.
Their study reveals that, as ant societies grew in complexity and numbers, they didn’t just make their workers smaller—they also made them cheaper.
In the insect world, the exoskeleton known as the cuticle serves as a protective barrier against predators, pathogens, and desiccation, while providing the structural framework for muscle attachment. But this protection comes at a price. Building a robust cuticle requires significant amounts of nitrogen and rare minerals like zinc and manganese. While skimping on armor for an individual insect may be a death sentence, the evolution of ants apparently found a way around it.
Trump’s energy secretary orders a Washington state coal plant to remain open
Science - Posted On:2025-12-19 13:45:00 Source: arstechnica
SEATTLE—The last coal-fired power plant in Washington state was set to go cold at the end of the year. It would then switch to natural gas, cutting carbon emissions in half.
The shutdown had been in the works for 15 years and was mandated by state law. It required the Canadian energy company that owns the power plant, TransAlta, to retrain workers and ease the local community’s economic transition.
But the farewell to coal was canceled this week by the Trump administration. In furtherance of the president’s crusade to keep America’s coal plants burning, the Department of Energy announced Tuesday that an “emergency exists” in the Pacific Northwest “due to a shortage of electricity.” To keep the lights on, Energy Secretary Chris Wright said that the Centralia electric generating facility in southwest Washington must continue to burn coal for at least 90 more days.
Rocket Report: Russia pledges quick fix for Soyuz launch pad; Ariane 6 aims high
Science - Posted On:2025-12-19 11:15:00 Source: arstechnica
Welcome to Edition 8.23 of the Rocket Report! Several new rockets made their first flights this year. Blue Origin’s New Glenn was the most notable debut, with a successful inaugural launch in January followed by an impressive second flight in November, culminating in the booster’s first landing on an offshore platform. Second on the list is China’s Zhuque-3, a partially reusable methane-fueled rocket developed by the quasi-commercial launch company LandSpace. The medium-lift Zhuque-3 successfully reached orbit on its first flight earlier this month, and its booster narrowly missed landing downrange. We could add China’s Long March 12A to the list if it flies before the end of the year. This will be the final Rocket Report of 2025, but we’ll be back in January with all the news that’s fit to lift.

Rocket Lab delivers for Space Force and NASA. Four small satellites rode a Rocket Lab Electron launch vehicle into orbit from Virginia early Thursday, beginning a government-funded technology demonstration mission to test the performance of a new spacecraft design, Ars reports. The satellites were nestled inside a cylindrical dispenser on top of the 59-foot-tall (18-meter) Electron rocket when it lifted off from NASA’s Wallops Flight Facility. A little more than an hour later, the rocket’s upper stage released the satellites one at a time at an altitude of about 340 miles (550 kilometers). The launch was the starting gun for a “proof of concept” mission to test the viability of a new kind of satellite called DiskSats, designed by the Aerospace Corporation.
Food Becoming More Calorific But Less Nutritious Due To Rising Carbon Dioxide
science - Posted On:2025-12-19 10:45:01 Source: slashdot
More carbon dioxide in the environment is making food more calorific but less nutritious -- and also potentially more toxic, a study has found. From a report: Sterre ter Haar, a lecturer at Leiden University in the Netherlands, and other researchers at the institution created a method to compare multiple studies on plants' responses to increased CO2 levels. The results, she said, were a shock: although crop yields increase, they become less nutrient-dense. While zinc levels in particular drop, lead levels increase. "Seeing how dramatic some of the nutritional changes were, and how this differed across plants, was a big surprise," she told the Guardian. "We aren't seeing a simple dilution effect but rather a complete shift in the composition of our foods... This also raises the question of whether we should adjust our diets in some way, or how we grow or produce our food." While scientists have been looking at the effects of more CO2 in the atmosphere on plants for a decade, their work has been difficult to compare. The new research established a baseline measurement derived from the observation that the gas appears to have a linear effect on growth, meaning that if the CO2 level doubles, so does the effect on nutrients. This made it possible to compare almost 60,000 measurements across 32 nutrients and 43 crops, including rice, potatoes, tomatoes and wheat. Read more of this story at Slashdot.

Swearing Actually Seems To Make Humans Physically Stronger
science - Posted On:2025-12-18 20:45:01 Source: slashdot
alternative_right shares a report from ScienceAlert: A new study adds to the growing body of evidence that swearing can help us unleash our inner strength, improving physical performance, it seems, by helping people break through certain psychological barriers. [...] [Psychology researcher Richard Stephens of Keele University in the UK] and his colleagues at Keele and the University of Alabama wanted to test whether swearing could not only improve physical performance, as they had done in previous research, but also see whether it does so by changing a person's psychology in the moment, especially when it comes to letting go of inhibitions. Eighty-eight participants, aged 18 to 65, all in good enough shape to exert themselves physically, were recruited at a university campus to participate in the first experiment. They each selected a pair of words based on the following prompts: a swear word you might utter after bumping your head, and a neutral word you might use to describe a table. Then, they undertook a chair push-up, which involves sitting in a chair and, holding each side of the seat, using your arms to lift your entire body weight (bottom off the chair, feet off the floor). [...] Both experiments suggested that swearing offers an advantage in physical performance, with participants achieving longer chair push-up hold times as they repeated their foul-mouthed mantras. Scores for positive emotion, humor, distraction, and novelty were also elevated in the swearing tests, which suggests invoking their favorite four-letter word might enable people to transition into more action-oriented states, and perhaps actually enjoy their workout more.

Parasites plagued Roman soldiers at Hadrian’s Wall
Science - Posted On:2025-12-18 20:15:00 Source: arstechnica
It probably sucked to be a Roman soldier guarding Hadrian’s Wall circa the third century CE. W.H. Auden imagined the likely harsh conditions in his poem “Roman Wall Blues,” in which a soldier laments enduring wet wind and rain with “lice in my tunic and a cold in my nose.” We can now add chronic nausea and bouts of diarrhea to his list of likely woes, thanks to parasitic infections, according to a new paper published in the journal Parasitology.
As previously reported, archaeologists can learn a great deal by studying the remains of intestinal parasites in ancient feces. For instance, in 2022, we reported on an analysis of soil samples collected from a stone toilet found within the ruins of a swanky 7th-century BCE villa just outside Jerusalem. That analysis revealed the presence of parasitic eggs from four different species: whipworm, beef/pork tapeworm, roundworm, and pinworm. (It’s the earliest record of roundworm and pinworm in ancient Israel.)
Later that same year, researchers from the University of Cambridge and the University of British Columbia analyzed the residue on an ancient Roman ceramic pot excavated at the site of a 5th-century CE Roman villa at Gerace, a rural district in Sicily. They identified the eggs of intestinal parasitic worms commonly found in feces—strong evidence that the 1,500-year-old pot in question was most likely used as a chamber pot.
LLMs’ impact on science: Booming publications, stagnating quality
Science - Posted On:2025-12-18 16:30:00 Source: arstechnica
There have been a number of high-profile cases where scientific papers have had to be retracted because they were filled with AI-generated slop—the most recent coming just two weeks ago. These instances raise serious questions about the quality of peer review in some journals—how could anyone let a figure with terms like “runctitional,” “fexcectorn,” and “frymblal” through, especially given the ‘m’ in frymblal has an extra hump? But it has not been clear whether these high-profile examples are representative. How significantly has AI use been influencing the scientific literature?
A collaboration of researchers at Berkeley and Cornell have decided to take a look. They’ve scanned three of the largest archives of pre-publication papers and identified ones that are likely to have been produced using Large Language Models. And they found that, while researchers produce far more papers after starting to use AI and the quality of the language used went up, the publication rate of these papers has dropped.
The researchers began by obtaining the abstracts of everything placed in three major pre-publication archives between 2018 and mid-2024. At the arXiv, this netted them 1.2 million documents; another 675,000 were found in the Social Science Research Network; and bioRxiv provided another 220,000. So, this was both a lot of material to work with and covered a lot of different fields of research. It also included documents that were submitted before Large Language Models were likely to be able to produce output that would be deemed acceptable.
