In November of 2022, "More than 800 people were selected to participate in the Denver Basic Income Project," reports the Colorado Sun, "while they were living on the streets, in shelters, on friends' couches or in vehicles.

One group received $1,000 a month, according to the article, while a second group received $6,500 in the first month, and then $500 for the next 11 months. (And a "control" group received $50 a month.) Amazingly, about 45% of participants in all three groups "were living in a house or apartment that they rented or owned by the study's 10-month check-in point, according to the research." The number of nights spent in shelters among participants in the first and second groups decreased by half. And participants in those two groups reported an increase in full-time work, while the control group reported decreased full-time employment. The project also saved tax dollars, according to the report. Researchers tallied an estimated $589,214 in savings on public services, including ambulance rides, visits to hospital emergency departments, jail stays and shelter nights...

The study, which began in November 2022 with payments to the first group of participants, has been extended for an additional eight months, until September, and organizers are attempting to raise money to extend it further.

Peter Scarfe, a researcher at the University of Reading's School of Psychology and Clinical Language Sciences, conducted an experiment testing the vulnerability of their examination system to AI-generated work. Using ChatGPT-4, Scarfe's team submitted over 30 AI-generated answers across multiple undergraduate psychology modules, finding that 94 percent of these submissions went undetected and nearly 84 percent received higher grades than human counterparts. The findings have been published in the journal PLOS One. Ars Technica reports: Scarfe's team submitted AI-generated work in five undergraduate modules, covering classes needed during all three years of study for a bachelor's degree in psychology. The assignments were either 200-word answers to short questions or more elaborate essays, roughly 1,500 words long. "The markers of the exams didn't know about the experiment. In a way, participants in the study didn't know they were participating in the study, but we've got necessary permissions to go ahead with that," Scarfe claims. Shorter submissions were prepared simply by copy-pasting the examination questions into ChatGPT-4 along with a prompt to keep the answer under 160 words. The essays were solicited the same way, but the required word count was increased to 2,000. Setting the limits this way, Scarfe's team could get ChatGPT-4 to produce content close enough to the required length. "The idea was to submit those answers without any editing at all, apart from the essays, where we applied minimal formatting," says Scarfe.

Overall, Scarfe and his colleagues slipped 63 AI-generated submissions into the examination system. Even with no editing or efforts to hide the AI usage, 94 percent of those went undetected, and nearly 84 percent got better grades (roughly half a grade better) than a randomly selected group of students who took the same exam. "We did a series of debriefing meetings with people marking those exams and they were quite surprised," says Scarfe. Part of the reason they were surprised was that most of those AI submissions that were detected did not end up flagged because they were too repetitive or robotic -- they got flagged because they were too good.

Out of five modules where Scarfe's team submitted AI work, there was one where it did not receive better grades than human students: the final module taken by students just before they left the university. "Large language models can emulate human critical thinking, analysis, and integration of knowledge drawn from different sources to a limited extent. In their last year at the university, students are expected to provide deeper insights and use more elaborate analytical skills. The AI isn't very good at that, which is why students fared better," Scarfe explained. All those good grades Chat GPT-4 got were in the first- and second-year exams, where the questions were easier. "But the AI is constantly improving, so it's likely going to score better in those advanced assignments in the future. And since AI is becoming part of our lives and we don't really have the means to detect AI cheating, at some point we are going to have to integrate it into our education system," argues Scarfe. He said the role of a modern university is to prepare the students for their professional careers, and the reality is they are going to use various AI tools after graduation. So, they'd be better off knowing how to do it properly.

Researchers in South Africa have injected radioactive material into the horns of 20 rhinos to deter poaching, aiming to leverage existing radiation detectors at borders for early detection and interception of trafficked horns. The Associated Press reports: The research, which has included the participation of veterinarians and nuclear experts, begins with the animal being tranquilized before a hole is drilled into its horn and the nuclear material carefully inserted. This week, researchers at the University of the Witwatersrand's Radiation and Health Physics Unit in South Africa injected 20 live rhinos with these isotopes. They hope the process can be replicated to save other wild species vulnerable to poaching -- like elephants and pangolins. "We are doing this because it makes it significantly easier to intercept these horns as they are being trafficked over international borders, because there is a global network of radiation monitors that have been designed to prevent nuclear terrorism," said Professor James Larkin, who heads the project. "And we're piggybacking on the back of that."

According to figures by the International Union for Conservation of Nature, an international conservation body, the global rhino population stood at around 500,000 at the beginning of the 20th century. It now stands at around 27,000 due to continued demand for rhino horns on the black market. South Africa has the largest population of rhinos with an estimated 16,000, making it a hotspot with over 500 rhinos killed yearly. [...] While the idea has received support from some in the industry, the researchers have had to jump many ethical hurdles posed by critics of their methodology.

Pelham Jones, chairperson of the Private Rhino Owners Association, is among the critics of the proposed method and doubts that it would effectively deter poachers and traffickers. "(Poachers) have worked out other ways of moving rhino horn out of the country, out of the continent or off the continent, not through traditional border crossings," he said. "They bypass the border crossings because they know that is the area of the highest risk of confiscation or interception." Professor Nithaya Chetty, dean of the science faculty at Witwatersrand, said the dosage of the radioactivity is very low and its potential negative impact on the animal was tested extensively.

An anonymous reader quotes a report from Ars Technica: The Internet Archive (IA) went before a three-judge panel Friday to defend its open library's controlled digital lending (CDL) practices after book publishers last year won a lawsuit claiming that the archive's lending violated copyright law. In the weeks ahead of IA's efforts to appeal that ruling, IA was forced to remove 500,000 books from its collection, shocking users. In an open letter to publishers, more than 30,000 readers, researchers, and authors begged for access to the books to be restored in the open library, claiming the takedowns dealt "a serious blow to lower-income families, people with disabilities, rural communities, and LGBTQ+ people, among many others," who may not have access to a local library or feel "safe accessing the information they need in public."

During a press briefing following arguments in court Friday, IA founder Brewster Kahle said that "those voices weren't being heard." Judges appeared primarily focused on understanding how IA's digital lending potentially hurts publishers' profits in the ebook licensing market, rather than on how publishers' costly ebook licensing potentially harms readers. However, lawyers representing IA -- Joseph C. Gratz, from the law firm Morrison Foerster, and Corynne McSherry, from the nonprofit Electronic Frontier Foundation -- confirmed that judges were highly engaged by IA's defense. Arguments that were initially scheduled to last only 20 minutes stretched on instead for an hour and a half. Ultimately, judges decided not to rule from the bench, with a decision expected in the coming months or potentially next year. McSherry said the judges' engagement showed that the judges "get it" and won't make the decision without careful consideration of both sides.

"They understand this is an important decision," McSherry said. "They understand that there are real consequences here for real people. And they are taking their job very, very seriously. And I think that's the best that we can hope for, really." On the other side, the Association of American Publishers (AAP), the trade organization behind the lawsuit, provided little insight into how the day went. When reached for comment, AAP simply said, "We thought it was a strong day in court, and we look forward to the opinion." [...] "There is no deadline for them to make a decision," Gratz said, but it "probably won't happen until early fall" at the earliest. After that, whichever side loses will have an opportunity to appeal the case, which has already stretched on for four years, to the Supreme Court. Since neither side seems prepared to back down, the Supreme Court eventually weighing in seems inevitable.

An anonymous reader shares a report: Bill Gates has defended the rapid rise in energy use caused by AI systems, arguing the technology would ultimately offset its heavy consumption of electricity. Speaking in London, Gates urged environmentalists and governments to "not go overboard" on concerns about the huge amounts of power required to run new generative AI systems, as Big Tech companies such as Microsoft race to invest tens of billions of dollars in vast new data centres.

Data centres will drive a rise in global electricity usage of between 2-6 per cent, the billionaire said. "The question is, will AI accelerate a more than 6 per cent reduction? And the answer is: certainly," said Gates, the Microsoft co-founder who has been a prolific investor in companies developing sustainable energy and carbon- reduction technologies. In May, Microsoft admitted that its greenhouse gas emissions had risen by almost a third since 2020, in large part due to the construction of data centres.

Gates, who left Microsoft's board in 2020 but remains an adviser to chief executive Satya Nadella, said tech companies would pay a "green premium" -- or higher price -- for clean energy as they seek new sources of power, which was helping to drive its development and deployment. "The tech companies are the people willing to pay a premium and to help bootstrap green energy capacity," he said at the Breakthrough Energy Summit in London on Thursday.

For the first two decades of the social internet, lurkers ruled. Among Gen Z, they're in the minority, according to survey data from YouTube. From a report: Tech industry insiders used to cite a rule of thumb stating that only one in ten of an online community's users generally post new content, with the masses logging on only to consume images, video or other updates. Now younger generations are flipping that divide, a survey by the video platform said. YouTube found that 65 percent of Gen Z, which it defined as people between the ages of 14 and 24, describe themselves as video content creators -- making lurkers a minority.

The finding came from responses from 350 members of Gen Z in the U.S., out of a wider survey that asked thousands of people about how they spend time online, including whether they consider themselves video creators. YouTube did the survey in partnership with research firm SmithGeiger, as part of its annual report on trends on the platform. YouTube's report says that after watching videos online, many members of Gen Z respond with videos of their own, uploading their own commentary, reaction videos, deep dives into content posted by others and more. This kind of interaction often develops in response to videos on pop culture topics such as "RuPaul's Drag Race" or the Fallout video game series. Fan-created content can win more watch time than the original source material, the report says.

The Supreme Court on Friday overturned a long-standing legal doctrine in the US, making a transformative ruling that could hamper federal agencies' ability to regulate all kinds of industry. The Verge adds: Six Republican-appointed justices voted to overturn the doctrine, called Chevron deference, a decision that could affect everything from pollution limits to consumer protections in the US.

Chevron deference allows courts to defer to federal agencies when there are disputes over how to interpret ambiguous language in legislation passed by Congress. That's supposed to lead to more informed decisions by leaning on expertise within those agencies. By overturning the Chevron doctrine, the conservative-dominated SCOTUS decided that judges ought to make the call instead of agency experts.

The SEC sued Ethereum software provider ConsenSys over its MetaMask service on Friday, alleging the wallet product was an unregistered broker that "engaged in the offer and sale of securities." From a report: MetaMask also offered an unregistered securities program through its staking service, the SEC alleged in a filing in the courthouse in the Eastern District of New York. The SEC alleged in its lawsuit that it offered staking services for Lido and Rocket Pool as investment contracts, meaning they are also unregistered securities. "Consensys has collected over $250 million in fees," the SEC alleged. You can read the full lawsuit here [PDF].

An anonymous reader shares a report: A top executive at McDonald's says the chain does not have plans to bring back plant-based options after a test of its McPlant burger in San Francisco and Dallas failed. "It was not successful in either market," Joe Erlinger, McDonald's U.S. president, said during the Wall Street Journal Global Food Forum in Chicago on Wednesday.

American consumers are not coming to McDonald's looking for a McPlant burger or other plant-based proteins, Erlinger added. The chain had previously partnered with Beyond Meat to make McPlant burgers and nuggets. Plant-based items are off the menu for now, but Erlinger didn't rule out the possibility that salads could one day make a return. That'll depend on whether customer demand is there.

"If people really want salads from McDonald's, we will gladly relaunch salads," Erlinger said. "But what our experience has proven is that's not what the consumer is looking for from McDonald's." Instead, consumers are looking for french fries, $5 meal deals, and hot, fresh sandwiches, he added.

Mark Zuckerberg has criticized the notion of a singular, dominant AI in a new interview. He argued against the idea of AI technology being "hoarded" by one company, taking aim at unnamed competitors who he suggested view themselves as "creating God." Zuckerberg advocated for open-source AI development, emphasizing the need for diverse AI systems reflecting varied interests.

He likened the future AI landscape to the current ecosystem of phone apps, content creators, and businesses, where no single entity dominates. Meta announced early U.S. tests of AI Studio, software enabling creators to build AI avatars for Instagram messaging. These AIs will be clearly labeled to avoid confusion. Zuckerberg stressed the importance of empowering many to experiment with AI, stating, "That's what culture is, right? It's not one group of people getting to dictate everything for people."

A former Boeing contractor has filed complaints with federal agencies, alleging safety issues in 787 Dreamliner production and wrongful termination. Richard Cuevas, a veteran mechanic, claims he observed improper drilling of fastener holes in forward pressure bulkheads during his work with Spirit AeroSystems, Boeing's main supplier.

Cuevas warned that these defects could compromise aircraft safety. After reporting concerns to the FAA and his superiors, Cuevas says he was fired. His lawyers have urged investigations into Dreamliner bulkheads and claim unlawful retaliation. Boeing stated they investigated the concerns thoroughly and determined no safety risk.

Many American subscribers are unable to use their phones overseas because all three major U.S. carriers are experiencing outages. According to The Register, the outages have been ongoing for several hours and stem from third-party communications technology company Syniverse. From the report: "Since the onset of these issues, Syniverse has been working closely with our network partners to restore full service," Syniverse, a US-based comms provider that focuses on roaming services, said in a statement confirming the breakdown. "We understand the inconvenience this has caused and appreciate your patience as we navigate this challenge."

"We're one of several providers impacted by a third-party vendor's issue that is intermittently affecting some international roaming service," T-Mo told us. "We're working with them to resolve it." Similarly, AT&T stated: "The AT&T network is operating normally. Some customers traveling internationally may be experiencing service disruptions due to an issue outside the AT&T network. We're working with one of our roaming connectivity providers to resolve the issue." Likewise, Verizon said, "An international third party communications provider is having issues with making voice and data connections with US based customers traveling overseas."

The international roaming outage has hit users' ability to do calls and texts, and reach the internet. According to Verizon, it's not a complete blackout. "70 percent of calls and data connections are going through at this time," the carrier firm told The Register in the past hour or so. Developing...

The FCC wants to make it significantly easier for consumers to unlock their phones from their carriers, proposing that all devices must be unlockable just 60 days after purchase. From a report: How this will mesh with current plans and phone buying trends, however, is something the agency is hoping to learn before putting such a rule into effect. Mobile phones purchased from a carrier are generally locked to that carrier until either the contract is up or the phone is paid off. But despite improvements to the process over the years (unlocking was flat-out illegal not long ago), it still isn't quite clear to all consumers when and how they can unlock their phone and take it to the carrier (or country) of their choice.

FCC Chairwoman Jessica Rosenworcel announced the Notice of Proposed Rulemaking, or NPRM, in a press release today. "When you buy a phone, you should have the freedom to decide when to change service to the carrier you want and not have the device you own stuck by practices that prevent you from making that choice," she wrote. "That is why we are proposing clear, nationwide mobile phone unlocking rules." Specifically, the release says, carriers would simply have to provide unlocking services 60 days after activation. A welcome standard, but it may run afoul of today's phone and wireless markets.

The number of climate lawsuits filed against companies around the world is rising swiftly, a report has found, and a majority of cases that have concluded have been successful. From a report: About 230 climate-aligned lawsuits have been filed against corporations and trade associations since 2015, two-thirds of which have been initiated since 2020, according to the analysis published on Thursday by the Grantham Research Institute on Climate Change and the Environment. One of the most rapidly growing forms of litigation is over "climate-washing" -- when companies are accused of misrepresenting their progress towards environmental targets -- and the analysis found that 47 such cases were filed against companies and governments in 2023.

As climate communications are increasingly scrutinised, there has been arise in climate-washing litigation, often with positive outcomes for those bringing the cases. Of the 140 climate-washing cases reviewed between 2016 and 2023, 77 have officially concluded, 54 of which ended with a ruling in favour of the claimant. More than 30 cases in 2023 concerned the "polluter pays" principle, whereby companies are held accountable for climate damage caused by high greenhouse gas emissions. The authors also highlighted six "turning off the taps" cases, which challenge the flow of finance to areas which hinder climate goals.

The Supreme Court decided to press pause on the Environmental Protection Agency's plan to prevent smog-forming pollutants from drifting across state borders. From a report: Ohio, Indiana, West Virginia, and various trade organizations including fossil fuel industry groups asked the Supreme Court to issue a stay on the plan while they contest the EPA's actions in lower courts. SCOTUS agreed to put the plan on hold today in its opinion on Ohio v. Environmental Protection Agency. Five justices voted in favor of halting implementation for now, while the remaining justices dissented.

"If anything, we see one reason for caution after another," Justice Neil Gorsuch writes in his opinion. While the stay is temporary, the decision signals that the conservative-leaning Supreme Court is likely to rule in favor of states opposing the EPA's plan if the issue makes it to the nation's highest court again for a final decision on the plan's legal merit. That could make it harder to improve air quality across the nation since air pollutants typically don't stay in one place.

Publicly traded crypto exchange Coinbase, in connection with History Associates Incorporated, has filed two civil lawsuits against the Securities and Exchange Commission and Federal Deposit Insurance Corporation for their failure to comply with FOIA requests. From a report: The Freedom of Information Act, or FOIA, grants the full or partial disclosure of previously unreleased information that's controlled by the U.S. government. Generally speaking, agencies have 20 days to respond -- not necessarily satisfy -- these requests. And even when government agencies do furnish documents, they can redact anything that falls under certain exemptions: Information related to national security, internal personnel, trade secrets, law enforcement, or financial institution records.

Late last year, Coinbase hired History Associates Incorporated, a private historical research firm, to submit a FOIA request on its behalf. The San Francisco crypto exchange was seeking copies of "Pause Letters" sent to financial institutions asking them to indefinitely cease all "crypto-related activities," according to the complaint. The letters were described in a report from the FDIC's Office of Inspector General (OIG), but never shared publicly. The OIG said the letters presented a "risk that the FDIC would inadvertently limit financial institution innovation and growth in the crypto space." The FDIC refused to provide History Associates or Coinbase with the letters.

An anonymous reader quotes a report from CNN: Dairy farmers in Denmark face having to pay an annual tax of 672 krone ($96) per cow for the planet-heating emissions they generate. The country's coalition government agreed this week to introduce the world's first carbon emissions tax on agriculture. It will mean new levies on livestock starting in 2030. Denmark is a major dairy and pork exporter, and agriculture is the country's biggest source of emissions. The coalition agreement -- which also entails investing 40 billion krone ($3.7 billion) in measures such as reforestation and establishing wetlands -- is aimed at helping the country meet its climate goals.

"With today's agreement, we are investing billions in the biggest transformation of the Danish landscape in recent times," Foreign Minister Lars Lokke Rasmussen said in a statement Tuesday. "At the same time, we will be the first country in the world with a (carbon) tax on agriculture." The Danish dairy industry broadly welcomed the agreement and its goals, but it has angered some farmers. [...] The tax, expected to be approved by Denmark's parliament later this year, will amount to 300 krone ($43) per tonne (1.1 ton) of CO2-equivalent emissions from livestock from 2030, rising to 750 krone ($107) in 2035. A 60% tax break will apply, meaning that farmers will effectively be charged 120 krone ($17) per tonne of livestock emissions per year from 2030, rising to 300 krone ($43) in 2035.

On average, Danish dairy cows, which account for much of the cattle population, emit 5.6 tons of CO2-equivalent per year, according to Concito, a green think tank in Denmark. Using the lower tax rate of 120 krone results in a charge of 672 krone per cow, or $96. With the tax break in place, that levy will rise to 1,680 krone per cow in 2035 ($241). In the first two years, the proceeds from the tax will be used to support the agricultural industry's green transition and then reassessed. "The whole purpose of the tax is to get the sector to look for solutions to reduce emissions," Concito's chief economist Torsten Hasforth told CNN. For example, farmers could change the feed they use.

Exam submissions generated by AI can not only evade detection but also earn higher grades than those submitted by university students, a real-world test has shown. From a report: The findings come as concerns mount about students submitting AI-generated work as their own, with questions being raised about the academic integrity of universities and other higher education institutions. It also shows even experienced markers could struggle to spot answers generated by AI, the University of Reading academics said.

Peter Scarfe, an associate professor at Reading's School of Psychology and Clinical Language Sciences said the findings should serve as a "wake-up call" for educational institutions as AI tools such as ChatGPT become more advanced and widespread. He said: "The data in our study shows it is very difficult to detect AI-generated answers. There has been quite a lot of talk about the use of so-called AI detectors, which are also another form of AI but (the scope here) is limited." For the study, published in the journal Plos One, Prof Scarfe and his team generated answers to exam questions using GPT-4 and submitted these on behalf of 33 fake students. Exam markers at Reading's School of Psychology and Clinical Language Sciences were unaware of the study. Answers submitted for many undergraduate psychology modules went undetected in 94% of cases and, on average, got higher grades than real student submissions, Prof Scarfe said.

Air freight operators have increased their greenhouse gas emissions by 25% compared to 2019, according to a report [PDF] by campaign group Stand.earth. The analysis found that operators ran about 300,000 more flights in 2023 than in 2019, a 30% increase in volume. The United States accounted for over 40% of global air freight emissions. The Guardian adds: FedEx and UPS were responsible for 24.7% of the industry's carbon emissions in 2023. It is estimated that 99.8% of aviation fuel is produced from fossil fuels, with the scaling of low carbon replacements a distant prospect. Research published last year forecast that global annual parcel volume could increase to 800bn parcels a year by 2030 [PDF], compared with 315bn in 2022.

The US Conference of Mayors, which speaks for the administrations of more than 1,400 cities with a population of at least 30,000 people, adopted a resolution over the weekend at its annual meeting that voiced an objection to HR 3557, a draft law known as the American Broadband Deployment Act of 2023. From a report: The bill, which was introduced by House Rep Earl Carter (R-GA) last May and is awaiting further consideration by Congress, is ostensibly designed to make it easier for telcos to build infrastructure and run additional cables on state and locally managed land, ideally allowing fast broadband connectivity to reach more and more folks.

Rep Carter went as far as saying his proposals will ensure "more Americans have access to internet and the United States can maintain its competitive edge against China." Meanwhile, the mayors say HR 3557 strips local governments of authority to oppose bad projects. What raises particular ire are provisions in the draft law that would provide a very short window for opposition. What we have here, basically, is a classic example of one side trying to strip away what is perceived to be bureaucracy and red tape, and the other side insisting that checks and balances are sorely needed.
