An anonymous reader shares a report: An airport made of bamboo? A tower reaching 20 metres high? For many years, bamboo has been mostly known as the favourite food of giant pandas, but a group of engineers say it's time we took it seriously as a building material, too.

This week the Institution of Structural Engineers called for architects to be "bamboo-ready" as they published a manual for designing permanent buildings made of the material, in an effort to encourage low-carbon construction and position bamboo as a proper alternative to steel and concrete.

Bamboo has already been used for a number of boundary-pushing projects around the world. At Terminal 2 of Kempegowda international airport in Bengaluru, India, bamboo tubes make up the ceiling and pillars. The Ninghai bamboo tower in north-east China, which is more than 20 metres tall, is claimed to be the world's first high-rise building made using engineered bamboo.

At the Green School in Bali, a bamboo-made arc serves as the gymnasium and a striking example of how the material is reshaping sustainable architecture. The use of composite bamboo shear walls have proved to be resilient against earthquakes and extreme weather in countries such as Colombia and the Philippines, where sustainable, disaster-resilient housing has been built with locally sourced materials.

Claims that Chinese technology for AI lags the US are a "fairy tale," Arthur Mensch, the chief executive officer of Mistral, said. From a report: "China is not behind the West," Mensch said in an interview on Bloomberg Television at the World Economic Forum in Davos, Switzerland on Thursday. The capabilities of China's open-source technology is "probably stressing the CEOs in the US."

The remarks from the boss of one of Europe's leading AI companies diverge from other tech leaders at Davos, who reassured lawmakers and business chiefs that China is behind the cutting edge by months or years.

An expanded class-action lawsuit filed last Friday alleges that a member of Nvidia's data strategy team directly contacted Anna's Archive -- the sprawling shadow library hosting millions of pirated books -- to explore "including Anna's Archive in pre-training data for our LLMs."

Internal documents cited in the amended complaint show Nvidia sought information about "high-speed access" to the collection, which Anna's Archive charged tens of thousands of dollars for. According to the lawsuit, Anna's Archive warned Nvidia that its library was illegally acquired and maintained, then asked if the company had internal permission to proceed. The pirate library noted it had previously wasted time on other AI companies that couldn't secure approval. Nvidia management allegedly gave "the green light" within a week.

Anna's Archive promised access to roughly 500 terabytes of data, including millions of books normally only accessible through Internet Archive's controlled digital lending system. The lawsuit also alleges Nvidia downloaded books from LibGen, Sci-Hub, and Z-Library.

An anonymous reader quotes a report from Inside Climate News: Just 32 companies accounted for over half of global fossil carbon emissions in 2024, according to a report published Wednesday by the U.K.-based think tank InfluenceMap. That is down from 36 companies responsible for half the global CO2 emissions in 2023, and 38 companies five years ago. The analysis is the latest update to the Carbon Majors database, which tracks the world's largest oil, gas, coal and cement producers and uses production data to calculate the carbon emissions from each entity's production. The database, first developed by researcher Richard Heede and now hosted by InfluenceMap, quantifies current and historical emissions attributable to nearly 180 companies and provides annual updates. It is the only database of its kind tracking corporate-generated carbon emissions dating back to the start of the Industrial Revolution, research that's being used in efforts to hold major polluters accountable for climate harms.

Despite dire warnings from scientists about the consequences of accelerating climate change, fossil fuel production is continuing apace. Last year, fossil fuel CO2 emissions reached a record high, topping 38 billion metric tons. In 2024 these emissions were 37.4 billion metric tons -- up 0.8 percent from 2023 -- and traceable to 166 oil, gas, coal and cement producers, according to the report. Much of the global carbon emissions in 2024 came from state-owned entities, which represented 16 of the top 20 emitters. The five largest emitters overall -- Saudi Arabia's Aramco, Coal India, China's CHN Energy, National Iranian Oil Co. and Russia's Gazprom -- were all state-controlled, and accounted for 18 percent of the total fossil CO2 emissions in 2024.

ExxonMobil, Chevron, Shell, ConocoPhillips and BP -- the top five emitting investor-owned companies -- together were responsible for 5.5 percent of the total emissions in that year. Historically, ExxonMobil and Chevron rank in the top five for fossil carbon emissions generated from 1854 through 2024, accounting for 2.79 percent and 3.08 percent of overall carbon pollution, respectively. According to the analysis, the 178 entities in the database have generated 70 percent of fossil CO2 emissions since the start of the Industrial Revolution, and just 22 entities are responsible for one-third of these emissions. "Each year, global emissions become increasingly concentrated among a shrinking group of high-emitting producers, while overall production continues to grow. Simultaneously, these heavy emitters continue to use lobbying to obstruct a transition that the scientific community has known for decades is essential," said Emmett Connaire, senior analyst at InfluenceMap. The findings of the new analysis, he added, "underscore the growing importance of this kind of rigorous evidence in efforts to determine accountability for climate-related losses."

Ars Technica's Benj Edwards reports: On Saturday, tech entrepreneur Siqi Chen released an open source plugin for Anthropic's Claude Code AI assistant that instructs the AI model to stop writing like an AI model. Called "Humanizer," the simple prompt plugin feeds Claude a list of 24 language and formatting patterns that Wikipedia editors have listed as chatbot giveaways. Chen published the plugin on GitHub, where it has picked up over 1,600 stars as of Monday. "It's really handy that Wikipedia went and collated a detailed list of 'signs of AI writing,'" Chen wrote on X. "So much so that you can just tell your LLM to... not do that."

The source material is a guide from WikiProject AI Cleanup, a group of Wikipedia editors who have been hunting AI-generated articles since late 2023. French Wikipedia editor Ilyas Lebleu founded the project. The volunteers have tagged over 500 articles for review and, in August 2025, published a formal list of the patterns they kept seeing.

Chen's tool is a "skill file" for Claude Code, Anthropic's terminal-based coding assistant, which involves a Markdown-formatted file that adds a list of written instructions (you can see them here) appended to the prompt fed into the large language model (LLM) that powers the assistant. Unlike a normal system prompt, for example, the skill information is formatted in a standardized way that Claude models are fine-tuned to interpret with more precision than a plain system prompt. (Custom skills require a paid Claude subscription with code execution turned on.)

But as with all AI prompts, language models don't always perfectly follow skill files, so does the Humanizer actually work? In our limited testing, Chen's skill file made the AI agent's output sound less precise and more casual, but it could have some drawbacks: it won't improve factuality and might harm coding ability. [...] Even with its drawbacks, it's ironic that one of the web's most referenced rule sets for detecting AI-assisted writing may help some people subvert it.

An anonymous reader quotes a report from the New York Times: Weight-loss drugs like Ozempic have transformed millions of lives with easily administered treatments and quick results. Now it turns out the dropped pounds may have a surprising perk for airlines, too: lower fuel costs, as slimmer passengers lighten their aircraft's loads.

According to a study published last week by Jefferies, a financial services firm, the four largest U.S. carriers -- American Airlines, Delta Air Lines, Southwest Airlines and United Airlines -- could together save as much as $580 million per year on fuel thanks to weight-loss drugs, known as GLP-1s. One in eight U.S. adults said they were taking a GLP-1 in a November survey published by KFF, a nonprofit health research group. Fuel is among airlines' largest expenses. The Jefferies study estimates that the four airlines will together consume 16 billion gallons of fuel in 2026 at a total cost of $38.6 billion, nearly 20 percent of their total expenses.

The savings from skinnier passengers would amount to just 1.5 percent of fuel costs. But airlines and pilots must scrutinize even the smallest changes to a plane's weight and balance, and a lighter payload means each jet burns less fuel to generate the thrust necessary to fly. Investors could also stand to benefit: The researchers estimated that a 2 percent reduction in aircraft weight could boost earnings per share by about 4 percent. "Please note savings are before any lost snack sales," the Jefferies analysts added.

In an opinion piece for The Atlantic, senior editor Saahil Desai argues that media outlets are increasingly treating prediction markets like Polymarket and Kalshi as legitimate signals of reality. The risk, as Desai warns, is a future where news coverage amplifies manipulable betting odds and turns politics, geopolitics, and even tragedy into speculative gambling theater. Here's an excerpt from the report: [...] The problem is that prediction markets are ushering in a world in which news becomes as much about gambling as about the event itself. This kind of thing has already happened to sports, where the language of "parlays" and "covering the spread" has infiltrated every inch of commentary. ESPN partners with DraftKings to bring its odds to SportsCenter and Monday Night Football; CBS Sports has a betting vertical; FanDuel runs its own streaming network. But the stakes of Greenland's future are more consequential than the NFL playoffs.

The more that prediction markets are treated like news, especially heading into another election, the more every dip and swing in the odds may end up wildly misleading people about what might happen, or influencing what happens in the real world. Yet it's unclear whether these sites are meaningful predictors of anything. After the Golden Globes, Polymarket CEO Shayne Coplan excitedly posted that his site had correctly predicted 26 of 28 winners, which seems impressive -- but Hollywood awards shows are generally predictable. One recent study found that Polymarket's forecasts in the weeks before the 2024 election were not much better than chance.

These markets are also manipulable. In 2012, one bettor on the now-defunct prediction market Intrade placed a series of huge wagers on Mitt Romney in the two weeks preceding the election, generating a betting line indicative of a tight race. The bettor did not seem motivated by financial gain, according to two researchers who examined the trades. "More plausibly, this trader could have been attempting to manipulate beliefs about the odds of victory in an attempt to boost fundraising, campaign morale, and turnout," they wrote. The trader lost at least $4 million but might have shaped media attention of the race for less than the price of a prime-time ad, they concluded. [...]

The irony of prediction markets is that they are supposed to be a more trustworthy way of gleaning the future than internet clickbait and half-baked punditry, but they risk shredding whatever shared trust we still have left. The suspiciously well-timed bets that one Polymarket user placed right before the capture of Nicolas Maduro may have been just a stroke of phenomenal luck that netted a roughly $400,000 payout. Or maybe someone with inside information was looking for easy money. [...] As Tarek Mansour, Kalshi's CEO, has said, his long-term goal is to "financialize everything and create a tradable asset out of any difference in opinion." (Kalshi means "everything" in Arabic.) What could go wrong? As one viral post on X recently put it, "Got a buddy who is praying for world war 3 so he can win $390 on Polymarket." It's a joke. I think.

Just 32 fossil fuel companies were responsible for half the global carbon dioxide emissions driving the climate crisis in 2024, down from 36 a year earlier, a report has revealed. The Guardian: Saudi Aramco was the biggest state-controlled polluter and ExxonMobil was the largest investor-owned polluter. Critics accused the leading fossil fuel companies of "sabotaging climate action" and "being on the wrong side of history" but said the emissions data was increasingly being used to hold the companies accountable.

State-owned fossil fuel producers made up 17 of the top 20 emitters in the Carbon Majors report, which the authors said underscored the political barriers to tackling global heating. All 17 are controlled by countries that opposed a proposed fossil fuel phaseout at the Cop30 UN climate summit in December, including Saudi Arabia, Russia, China, Iran, the United Arab Emirates and India. More than 80 other nations had backed the phaseout plan.

The price of water and sewer services for American households has more than doubled since the early 1980s after adjusting for inflation, even though per-capita water use has actually decreased over that period. Households in large cities now spend about $1,300 a year on water and sewer charges, approaching the roughly $1,600 they spend on electricity. The main driver is federal regulation.

Since the Clean Water Act of 1972 and the Safe Drinking Water Act of 1974, the U.S. has spent approximately $5 trillion in contemporary dollars fighting water pollution -- about 0.8% of annual GDP across that period. The EPA itself admits that surface water regulations are the one category of environmental rules where estimated costs exceed estimated benefits.

New York City was required to build a filtration plant to address two minor parasites in water from its Croton aqueduct. The project took a decade longer than expected and cost $3.2 billion, more than double the original estimate. After the plant opened in 2015, the city's Commissioner of Environmental Protection noted that the water would basically be "the same" to the public. Jefferson County, Alabama, meanwhile, descended into what was then the largest municipal bankruptcy in U.S. history in 2011 after EPA-mandated sewer upgrades pushed its debt from $300 million to over $3 billion.

Google has temporarily disabled YouTube's advanced SRV3 caption format after discovering the feature was causing playback errors for some users, according to a statement the company posted. SRV3, also known as YouTube Timed Text, is a custom subtitle system Google introduced around 2018 that allows creators to use custom colors, transparency, animations, and precise text positioning. Creators cannot upload new SRV3 captions while the feature remains disabled, and existing videos that use the format may not display any captions until Google restores it. The company has provided no timeline for when SRV3 will return, and its forum post notes that changes should be temporary for "almost" all videos.

YouTube CEO Neal Mohan used his annual letter to creators, published Wednesday, to outline an ambitious 2026 vision that embraces AI-powered creative tools while simultaneously pledging to crack down on the low-quality AI content that has come to be known as "slop."

Mohan identified four AI-related areas that YouTube "must get right in 2026." The platform is working on tools that will let creators use AI to generate Shorts featuring their own likenesses and to experiment with music. "Just as the synthesizer, Photoshop and CGI revolutionized sound and visuals, AI will be a boon to the creatives who are ready to lean in," he wrote. Features like autodubbing, he says, will "transform the viewer experience."

But "the rise of AI has raised concerns about low-quality content, aka 'AI slop,'" he wrote. YouTube is building on its existing spam and clickbait detection systems to reduce the spread of such content. He also flagged deepfakes as a particular concern: "It's becoming harder to detect what's real and what's AI-generated." The platform plans to double down on AI labels and introduce tools that let creators protect their likenesses.

alternative_right shares a report from ScienceAlert: Thanks to a giant eruption on the Sun and a large opening in its atmosphere, we're currently experiencing G4 conditions -- a severe geomagnetic storm strong enough to disrupt power grids as energy from space weather disturbances drives electric currents through Earth's magnetic field and the ground. Experts say the storm could even reach G5 levels, the extreme category responsible for the spectacular auroral activity seen in May 2024. In fact, space weather bureaus around the world are forecasting powerful aurora conditions, with some suggesting aurora could be visible at unusually low latitudes, potentially rivaling the reach of 2024's historic superstorm. A livestream of the Northern Lights is available on YouTube. The Aurora forecast is available here.

An anonymous reader quotes a report from the Guardian: The world has entered an era of "global water bankruptcy" that is harming billions of people, a UN report has declared. The overuse and pollution of water must be tackled urgently, the report's lead author said, because no one knew when the whole system could collapse, with implications for peace and social cohesion. All life depends on water but the report found many societies had long been using water faster than it could be replenished annually in rivers and soils, as well as over-exploiting or destroying long-term stores of water in aquifers and wetlands. This had led to water bankruptcy, the report said, with many human water systems past the point at which they could be restored to former levels. The climate crisis was exacerbating the problem by melting glaciers, which store water, and causing whiplashes between extremely dry and wet weather.

Prof Kaveh Madani, who led the report, said while not every basin and country was water bankrupt, the world was interconnected by trade and migration, and enough critical systems had crossed this threshold to fundamentally alter global water risk. The result was a world in which 75% of people lived in countries classified as water-insecure or critically water-insecure and 2 billion people lived on ground that is sinking as groundwater aquifers collapse. Conflicts over water had risen sharply since 2010, the report said, while major rivers, such as the Colorado, in the US, and the Murray-Darling system, in Australia, were failing to reach the sea, and "day zero" emergencies -- when cities run out of water, such as in Chennai, India -- were escalating. Half of the world's large lakes had shrunk since the early 1990s, the report noted. Even damp nations, such as the UK, were at risk because of reliance on imports of water-dependent food and other products. "This report tells an uncomfortable truth: many critical water systems are already bankrupt," said Madani, of the UN University's Institute for Water, Environment and Health. "It's extremely urgent [because] no one knows exactly when the whole system would collapse."

About 70% of fresh water taken by human withdrawals was used for agriculture, but Madani said: "Millions of farmers are trying to grow more food from shrinking, polluted or disappearing water sources. Water bankruptcy in India or Pakistan, for example, also means an impact on rice exports to a lot of places around the world." More than half of global food was grown in areas where water storage was declining or unstable, the report said. Madani said action to deal with water bankruptcy offered a chance to bring countries together in an increasingly fragmented world. "Water is a strategic, untapped opportunity to the world to create unity within and between nations. It is one of the very rare topics that left and right and north and south all agree on its importance." The UN report, which is based on a forthcoming paper in the peer-reviewed journal Water Resources Management, sets out how population growth, urbanization and economic growth have increased water demand for agriculture, industry, energy and cities. "These pressures have produced a global pattern that is now unmistakable," it said.

An anonymous reader quotes a report from U.S. News & World Report: U.S. health officials plan a new study investigating whether radiation from cellphones may affect human health. A spokesperson for the U.S. Department of Health and Human Services (HHS) said the research will examine electromagnetic radiation and possible gaps in current science. The initiative stems from numerous concerns raised by Health Secretary Robert F. Kennedy Jr., who has linked cellphone use to neurological damage and cancer.

"The [U.S. Food and Drug Administration] removed webpages with old conclusions about cell phone radiation while HHS undertakes a study on electromagnetic radiation and health research to identify gaps in knowledge, including on new technologies, to ensure safety and efficacy," HHS spokesman Andrew Nixon said. He added that the study was directed in a strategy report from the president's Make America Healthy Again Commission.

Some webpages from the FDA and the U.S. Centers for Disease Control and Prevention say current research does not show clear harm from cellphone radiation. The National Cancer Institute, which is part of the National Institutes of Health, says that "evidence to date suggests that cellphone use does not cause brain or other kinds of cancer in humans.".

The UK government has launched a public consultation on whether to ban social media use for children under 16, drawing inspiration from Australia's recently enacted age-based restrictions. "It would also explore how to enforce that limit, how to limit tech companies from being able to access children's data and how to limit 'infinite scrolling,' as well as access to addictive online tools," reports Engadget. "In addition to seeking feedback from parents and young people themselves, the country's ministers are going to visit Australia to see the effects of the country's social media ban for kids, according to Financial Times."

Cointelegraph, once one of the most-visited cryptocurrency news sites, has seen its monthly traffic plummet from roughly 8 million visits to 1.4 million -- an 80% drop in three months -- after Google issued a manual penalty in October 2025 for the outlet's partnership with a blackhat SEO firm that used Cointelegraph's domain authority to promote affiliate links to offshore casinos and betting platforms.

The CEO, who had no prior media experience, proceeded despite warnings from Google earlier in 2025 and repeated objections from the outlet's three most senior editorial staff members throughout the year. The penalty removed Cointelegraph from Google News, Discover and search results entirely; a search for "Cointelegraph" now returns CoinDesk as the top result. Jon Rice, the former editor-in-chief, resigned on December 31st and described the situation as an "existential threat to business."

Amazon CEO Andy Jassy said President Donald Trump's sweeping tariffs are starting to be reflected in the price of some items, as sellers weigh how to absorb the shock of the added costs. From a report: Amazon and many of its third-party merchants pre-purchased inventory to try to get ahead of the tariffs and keep prices low for customers, but most of that supply ran out last fall, Jassy said in a Tuesday interview with CNBC's Becky Quick at the World Economic Forum in Davos, Switzerland.

"So you start to see some of the tariffs creep into some of the prices, some of the items, and you see some sellers are deciding that they're passing on those higher costs to consumers in the form of higher prices, some are deciding that they'll absorb it to drive demand and some are doing something in between," Jassy said. "I think you're starting to see more of that impact." The comments are a notable shift from last year, when Jassy said Amazon hadn't seen "prices appreciably go up" a few months after Trump announced wide-ranging tariffs. Further reading: Americans Are the Ones Paying for Tariffs, Study Finds: Americans, not foreigners, are bearing almost the entire cost of U.S. tariffs, according to new research that contradicts a key claim by President Trump and suggests he might have a weaker hand in a reemerging trade war with Europe.

[...] The new research, published Monday by the Kiel Institute for the World Economy, a well-regarded German think tank, suggests that the impact of tariffs is likely to show up over time in the form of higher U.S. consumer prices. [...] By analyzing $4 trillion of shipments between January 2024 and November 2025, the Kiel Institute researchers found that foreign exporters absorbed only about 4% of the burden of last year's U.S. tariff increases by lowering their prices, while American consumers and importers absorbed 96%.

A new study from Scripps Institution of Oceanography finds that factoring ocean damage into climate economics nearly doubles the estimated global cost of climate change, adding close to $2 trillion per year from losses to fisheries, coral reefs, and coastal infrastructure. "It is the first time a social cost of carbon (SCC) assessment -- a key measure of economic harm caused by climate change -- has included damages to the ocean," reports Inside Climate News. From the report: "For decades, we've been estimating the economic cost of climate change while effectively assigning a value of zero to the ocean," said Bernardo Bastien-Olvera, who led the study during his postdoctoral fellowship at Scripps. "Ocean loss is not just an environmental issue, but a central part of the economic story of climate change."

The social cost of carbon is an accounting method for working out the monetary cost of each ton of carbon dioxide released into the atmosphere. "[It] is one of the most efficient tools we have for internalizing climate damages into economic decision-making," said Amy Campbell, a United Nations climate advisor and former British government COP negotiator. Calculations have historically been used by international organizations and state departments like the U.S. Environmental Protection Agency to assess policy proposals -- though a 2025 White House memo from the Trump administration instructed federal agencies to ignore the data during cost-benefit analyses unless required by law. "It becomes politically contentious when deciding whose damages are counted, which sectors are included and most importantly how future and retrospective harms are valued," Campbell said.

Excluding ocean harm, the social cost of carbon is $51 per ton of carbon dioxide emitted. This increases to $97.20 per ton when the ocean, which covers 70 percent of the planet, is included. In 2024, global CO2 emissions were estimated to be 41.6 billion tons, making the 91 percent cost increase significant. Using greenhouse gas emission predictions, the report estimates the annual damages to traditional markets alone will be $1.66 trillion by 2100.

A former Bank of England analyst has urged contingency planning for a potential financial shock if the U.S. government were to confirm the existence of extraterrestrial intelligence. The argument is that "ontological shock" alone could destabilize confidence and trigger crisis dynamics. The Independent reports: [Helen McCaw, who served as a senior analyst in financial security at the UK's central bank and worked for the Bank of England for 10 years until 2012] said politicians and bankers can no longer afford to dismiss talk of alien life, and warned a declaration of this nature could trigger bank collapses. She reportedly said: "The United States government appears to be partway through a multi-year process to declassify and disclose information on the existence of a technologically advanced non-human intelligence responsible for Unidentified Anomalous Phenomena (UAPs)."

"If the UAP proves to be of non-human origin, we may have to acknowledge the existence of a power or intelligence greater than any government and with potentially unknown intentions." Her warning comes as senior American officials have recently indicated their belief in the possibility of alien life. [...] Ms McCaw said: "UAP disclosure is likely to induce ontological shock and provoke psychological responses with material consequences ... There might be extreme price volatility in financial markets due to catastrophising or euphoria, and a collapse in confidence if market participants feel uncertain on how to price assets using any of the familiar methods."

The former Bank of England worker explained there might be a rush towards assets such as gold or other precious metals, and government bonds, which are perceived as "safe." Alternatively, she said precious metals might lose their status as perceived safe assets if people speculate that new space-faring technologies will soon increase the supply of precious metals. The article cites a recent UFO documentary, The Age of Disclosure, where 34 U.S. government insiders, including those from the military and intelligence community officials, share insights about the governments work with UAP. Per the film's description, the documentary "reveals an 80-year global cover-up of non-human intelligent life and a secret war among major nations to reverse-engineer advanced technology of non-human origin."

Sphere Entertainment plans to build a second U.S. Sphere near Washington, D.C., with a smaller 6,000-seat "mini-Sphere" proposed for National Harbor in Maryland. The venue would retain the signature LED exterior and immersive 4D tech of the Las Vegas Sphere, just at a more compact scale. The Verge reports: The second US sphere would be built in an area known as National Harbor in Prince George's County, Maryland. Located along the Potomac River, National Harbor currently features a convention center, multiple hotels, restaurants, and shops. While Abu Dhabi plans to build a sphere as large as the one in Las Vegas, the National Harbor venue would be one of the first mini-Sphere venues announced last March.

Its capacity would be limited to 6,000 seats instead of over 17,000. But the smaller Sphere would still be hard to miss with an exterior LED exosphere for showcasing the "artistic and branded content" that helped make the original sphere a unique part of the Las Vegas skyline. The inside of the mini-Sphere will feature a high-resolution 16,000 by 16,000 pixel wrap-around screen, the company's immersive sound technology, haptic seating, and "4D environmental effects." For the AI-enhanced version of The Wizard of Oz currently playing in Las Vegas, audiences experience effects like wind, fog, smells, and apples falling from the ceiling.
