feel the heat —

Nine states are teaming up to accelerate adoption of this climate-friendly device.

Death is coming for the old-school gas furnace—and its killer is the humble heat pump. They’re already outselling gas furnaces in the US, and now a coalition of states has signed an agreement to supercharge the gas-to-electric transition by making it as cheap and easy as possible for their residents to switch.

Nine states have signed a memorandum of understanding that says that heat pumps should make up at least 65 percent of residential heating, air conditioning, and water-heating shipments by 2030. (“Shipments” here means systems manufactured, a proxy for how many are actually sold.) By 2040, these states—California, Colorado, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, and Rhode Island—are aiming for 90 percent of those shipments to be heat pumps.

“It’s a really strong signal from states that they’re committed to accelerating this transition to zero-emissions residential buildings,” says Emily Levin, senior policy adviser at the Northeast States for Coordinated Air Use Management (NESCAUM), an association of air-quality agencies, which facilitated the agreement. The states will collaborate, for instance, in pursuing federal funding, developing standards for the rollout of heat pumps, and laying out an overarching plan “with priority actions to support widespread electrification of residential buildings.”

Instead of burning planet-warming natural gas, a heat pump warms a building by transferring heat from the outdoor air into the interior space. Run it in the opposite direction, and it can cool the inside of a building—a heat pump is both a heater and AC unit. Because the system is electric, it can run off a grid increasingly powered by renewables like wind and solar. Even if you have to run a heat pump with electricity from fossil-fuel power plants, it’s much more efficient than a furnace, because it’s moving heat instead of creating it.

A heat pump can save an average American household over $550 a year, according to one estimate. They’ve gotten so efficient that even when it’s freezing out, they can still extract warmth from the air to heat a home. You can even install a heat pump system that also warms your water. “We really need consumers to move away from dirty to clean heat, and we really want to get the message out that heat pumps are really the way to go,” says Serena McIlwain, Maryland’s secretary of the environment. “We have homeowners who are getting ready to replace their furnaces, and if they’re not aware, they are not going to replace it with a heat pump.”

The coalition’s announcement comes just months after the federal government doubled down on its own commitment to heat pumps, announcing $169 million in funding for the domestic production of the systems. That money comes from 2022’s Inflation Reduction Act, which also provides an American household with thousands of dollars in rebates or tax credits to switch to a heat pump.

These states are aiming to further collaborate with those heat pump manufacturers by tracking sales and overall progress, sending a signal to the industry to ramp up production to meet the ensuing demand. They’ll also collaborate with each other on research and generally share information, working toward the best strategies for realizing the transition from gas to electric. Basically, they’re pursuing a sort of standardization of the policies and regulations for getting more heat pumps built, bought, and installed, which other states outside of the coalition might eventually tap into.

“A consistent approach between states helps to ease the market transition,” says Matt Casale, senior manager of appliance standards at the Building Decarbonization Coalition, which is collaborating with the Northeast States for Coordinated Air Use Management. “There are all of these manufacturers, and all of these contractors, all along the supply chain, trying to plan out their next several years. They want to know: What is it going to look like?”

There’s also the less-talked-about challenge of the green energy revolution: training enough technicians to actually install the heat pumps. To that end, the memorandum calls for workforce development and contractor training. “If we’re pushing heat pumps and more installations, and we don’t have enough electricians to do the job, we’re not going to meet the goal—period,” says McIlwain. “We do need to put a lot of money and energy and resources into making sure that we have the workforce available to do it.”

In addition to the technicians working with the systems, the country needs way more electricians to retrofit homes to go fully electric beyond heat pumps, with solar panels and induction stoves and home batteries. To help there, last year the White House announced the formation of the American Climate Corps, which aims to put more than 20,000 people to work in clean energy and overall climate resilience.

With states collaborating like this on heat pumps, the idea is to lift the device from an obscure technology cherished by climate nerds into ubiquity, for the good of consumers and the planet. “We need to be sending these unmistakable signals to the marketplace that heat pumps and zero-emission homes are the future,” says Casale. “This agreement between this many states really sets the stage for doing that.”

Collaboration comes as tech giant faces multibillion-dollar lawsuit from The New York Times.

Microsoft is working with media startup Semafor to use its artificial intelligence chatbot to help develop news stories—part of a journalistic outreach that comes as the tech giant faces a multibillion-dollar lawsuit from the New York Times.

As part of the agreement, Microsoft is paying an undisclosed sum of money to Semafor to sponsor a breaking news feed called “Signals.” The companies would not share financial details, but the amount of money is “substantial” to Semafor’s business, said a person familiar with the matter.

Signals will offer a feed of breaking news and analysis on big stories, with about a dozen posts a day. The goal is to offer different points of view from across the globe—a key focus for Semafor since its launch in 2022.

Semafor co-founder Ben Smith emphasized that Signals will be written entirely by journalists, with artificial intelligence providing a research tool to inform posts.

Microsoft on Monday was also set to announce collaborations with journalist organizations including the Craig Newmark School of Journalism, the Online News Association, and the GroundTruth Project.

The partnerships come as media companies have become increasingly concerned over generative AI and its potential threat to their businesses. News publishers are grappling with how to use AI to improve their work and stay ahead of technology, while also fearing that they could lose traffic, and therefore revenue, to AI chatbots—which can churn out humanlike text and information in seconds.

The New York Times in December filed a lawsuit against Microsoft and OpenAI, alleging the tech companies have taken a “free ride” on millions of its articles to build their artificial intelligence chatbots, and seeking billions of dollars in damages.

Gina Chua, Semafor’s executive editor, has been involved in developing Semafor’s AI research tools, which are powered by ChatGPT and Microsoft’s Bing.

“Journalism has always used technology whether it’s carrier pigeons, the telegraph or anything else . . . this represents a real opportunity, a set of tools that are really a quantum leap above many of the other tools that have come along,” Chua said.

For a breaking news event, Semafor journalists will use AI tools to quickly search for reporting and commentary from other news sources across the globe in multiple languages. A Signals post might include perspectives from Chinese, Indian, or Russian media, for example, with Semafor’s reporters summarizing and contextualizing the different points of view, while citing its sources.

Noreen Gillespie, a former Associated Press journalist, joined Microsoft three months ago to forge relationships with news companies. “Journalists need to adopt these tools in order to survive and thrive for another generation,” she said.

Semafor was founded by Ben Smith, the former BuzzFeed editor, and Justin Smith, the former chief executive of Bloomberg Media.

Semafor, which is free to read, is funded by wealthy individuals, including 3G capital founder Jorge Paulo Lemann and KKR co-founder Henry Kravis. The company made more than $10 million in revenue in 2023 and has more than 500,000 subscriptions to its free newsletters. Justin Smith said Semafor was “very close to a profit” in the fourth quarter of 2023.

“What we’re trying to go after is this really weird space of breaking news on the Internet now, in which you have these really splintered, fragmented, rushed efforts to get the first sentence of a story out for search engines . . . and then never really make any effort to provide context,” Ben Smith said.

“We’re trying to go the other way. Here are the confirmed facts. Here are three or four pieces of really sophisticated, meaningful analysis.”

Hermit crabs find new homes in plastic waste: Shell shortage or clever choice?

hermit crab in plastic pen cap

Enlarge / Scientists have found that hermit crabs are increasingly using plastic and other litter as makeshift shell homes.

Land hermit crabs have been using bottle tops, parts of old light bulbs and broken glass bottles, instead of shells.

New research by Polish researchers studied 386 images of hermit crabs occupying these artificial shells. The photos had been uploaded by users to online platforms, then analyzed by scientists using a research approach known as iEcology. Of the 386 photos, the vast majority, 326 cases, featured hermit crabs using plastic items as shelters.

At first glance, this is a striking example of how human activities can alter the behavior of wild animals and potentially the ways that populations and ecosystems function as a result. But there are lots of factors at play and, while it’s easy to jump to conclusions, it’s important to consider exactly what might be driving this particular change.

Shell selection

Hermit crabs are an excellent model organism to study because they behave in many different ways and those differences can be easily measured. Instead of continuously growing their own shell to protect their body, like a normal crab or a lobster would, they use empty shells left behind by dead snails. As they walk around, the shell protects their soft abdomen but whenever they are threatened they retract their whole body into the shell. Their shells act as portable shelters.

Having a good enough shell is critical to an individual’s survival so they acquire and upgrade their shells as they grow. They fight other hermit crabs for shells and assess any new shells that they might find for suitability. Primarily, they look for shells that are large enough to protect them, but their decision-making also takes into account the type of snail shell, its condition and even its color—a factor that could impact how conspicuous the crab might be.

Another factor that constrains shell choice is the actual availability of suitable shells. For some as yet unknown reason, a proportion of land hermit crabs are choosing to occupy plastic items rather than natural shells, as highlighted by this latest study.

Housing crisis or ingenious new move?

Humans have intentionally changed the behavior of animals for millennia through the process of domestication. Any unintended behavioral changes in natural animal populations are potentially concerning, but how worried should we be about hermit crabs using plastic litter as shelter?

The Polish research raises a number of questions. First, how prevalent is the adoption of plastic litter instead of shells? While 326 crabs using plastic seems like a lot, this is likely to be an underestimation of the raw number given that users are likely to encounter crabs only in accessible parts of the populations. Conversely, it seems probable that users could be biased towards uploading striking or unusual images, so the iEcology approach might produce an exaggerated impression of the proportion of individuals in a population opting for plastic over natural shells. We need structured field surveys to clarify this.

Second, why are some individual crabs using plastic? One possibility is that they are forced to due to a lack of natural shells, but we can’t test this hypothesis without more information on the demographics of local snail populations. Or perhaps the crabs prefer plastic or find it easier to locate, compared with real shells? As the authors point out, plastic might be lighter than the equivalent shells affording the same amount of protection but at lower energy cost of carrying them. Intriguingly, chemicals that leach out of plastic are known to attract marine hermit crabs by mimicking the odor of food.

As hermit crabs adapt to an increase in plastic pollution, more research is needed to investigate the nuances.

Enlarge / As hermit crabs adapt to an increase in plastic pollution, more research is needed to investigate the nuances.

This leads to a third question about the possible downsides of using plastic. Compared to real shells plastic waste tends to be brighter and might contrast more with the background making the crabs more vulnerable to predators. Additionally, we know that exposure to microplastics and compounds that leach from plastic can change the behaviour of hermit crabs, making them less fussy about the shells that they choose, less adept at fighting for shells and even changing their personalities by making them more prone to take risks. To answer these questions about the causes and consequences of hermit crabs using plastic waste in this way, we need to investigate their shell selection behavior through a series of laboratory experiments.

Pollution changes behavior

Plastic pollution is just one of the ways we are changing our environment. It’s by far the most highly reported form of debris that we have introduced to marine environments. But animal behavior is affected by other forms of pollution too, including microplastics, pharmaceuticals, light, and noise, plus the rising temperatures and ocean acidification caused by climate change.

So while investigating the use of plastic waste by hermit crabs could help us better understand the consequences of certain human impacts on the environment, it doesn’t show how exactly animals will adjust to the Anthropocene, the era during which human activity has been having a significant impact on the planet. Will they cope by using plastic behavioral responses or evolve across generations, or perhaps both? In my view, the iEcology approach cannot answer questions like this. Rather, this study acts as an alarm bell highlighting potential changes that now need to be fully investigated.

celestial nomads —

Two celestial interlopers in Solar System have scientists eagerly anticipating more.

The first interstellar interloper detected passing through the Solar System, 1l/‘Oumuamua, came within 24 million miles of the Sun in 2017

Enlarge / The first interstellar interloper detected passing through the Solar System, 1l/‘Oumuamua, came within 24 million miles of the Sun in 2017. It’s difficult to know exactly what ‘Oumuamua looked like, but it was probably oddly shaped and elongated, as depicted in this illustration.

On October 17 and 18, 2017, an unusual object sped across the field of view of a large telescope perched near the summit of a volcano on the Hawaiian island of Maui. The Pan-STARRS1 telescope was designed to survey the sky for transient events, like asteroid or comet flybys. But this was different: The object was not gravitationally bound to the Sun or to any other celestial body. It had arrived from somewhere else.

The mysterious object was the first visitor from interstellar space observed passing through the Solar System. Astronomers named it 1I/‘Oumuamua, borrowing a Hawaiian word that roughly translates to “messenger from afar arriving first.” Two years later, in August 2019, amateur astronomer Gennadiy Borisov discovered the only other known interstellar interloper, now called 2I/Borisov, using a self-built telescope at the MARGO observatory in Nauchnij, Crimea.

While typical asteroids and comets in the Solar System orbit the Sun, ‘Oumuamua and Borisov are celestial nomads, spending most of their time wandering interstellar space. The existence of such interlopers in the Solar System had been hypothesized, but scientists expected them to be rare. “I never thought we would see one,” says astrophysicist Susanne Pfalzner of the Jülich Supercomputing Center in Germany. At least not in her lifetime.

With these two discoveries, scientists now suspect that interstellar interlopers are much more common. Right now, within the orbit of Neptune alone, there could be around 10,000 ‘Oumuamua-size interstellar objects, estimates planetary scientist David Jewitt of UCLA, coauthor of an overview of the current understanding of interstellar interlopers in the 2023 Annual Review of Astronomy and Astrophysics.

Researchers are busy trying to answer basic questions about these alien objects, including where they come from and how they end up wandering the galaxy. Interlopers could also provide a new way to probe features of distant planetary systems.

But first, astronomers need to find more of them.

“We’re a little behind at the moment,” Jewitt says. “But we expect to see more.”

2I/Borisov appears as a fuzzy blue dot in front of a distant spiral galaxy (left) in this November 2019 image taken by the Hubble Space Telescope when the object was approximately 200 million miles from Earth.

Alien origins

At least since the beginning of the 18th century, astronomers have considered the possibility that interstellar objects exist. More recently, computer models have shown that the Solar System sent its own population of smaller bodies into the voids of interstellar space long ago due to gravitational interactions with the giant planets.

Scientists expected most interlopers to be exocomets composed of icy materials. Borisov fit this profile: It had a tail made of gases and dust created by ices that evaporated during its close passage to the Sun. This suggests that it originated in the outer region of a planetary system where temperatures were cold enough for gases like carbon monoxide to have frozen into its rocks. At some point, something tossed Borisov, roughly a kilometer across, out of its system.

One potential culprit is a stellar flyby. The gravity of a passing star can eject smaller bodies, known as planetesimals, from the outer reaches of a system, according to a recent study led by Pfalzner. A giant planet could also eject an object from the outer regions of a planetary system if an asteroid or comet gets close enough for the planet’s gravitational tug to speed up the smaller body enough for it to escape its star’s hold. Close approaches can also happen when planets migrate across their planetary systems, as Neptune is thought to have done in the early Solar System.

Anti-censorship voices are working to highlight reports of one Indian company’s hacker past.

A startup allegedly “hacked the world.” Then came the censorship—and now the backlash.

Hacker-for-hire firms like NSO Group and Hacking Team have become notorious for enabling their customers to spy on vulnerable members of civil society. But as far back as a decade ago in India, a startup called Appin Technology and its subsidiaries allegedly played a similar cyber-mercenary role while attracting far less attention. Over the past two years, a collection of people with direct and indirect links to that company have been working to keep it that way, using a campaign of legal threats to silence publishers and anyone else reporting on Appin Technology’s alleged hacking past. Now, a loose coalition of anti-censorship voices is working to make that strategy backfire.

For months, lawyers and executives with ties to Appin Technology and to a newer organization that shares part of its name, called the Association of Appin Training Centers, have used lawsuits and legal threats to carry out an aggressive censorship campaign across the globe. These efforts have demanded that more than a dozen publications amend or fully remove references to the original Appin Technology’s alleged illegal hacking or, in some cases, mentions of that company’s co-founder, Rajat Khare. Most prominently, a lawsuit against Reuters brought by the Association of Appin Training Centers resulted in a stunning order from a Delhi court: It demanded that Reuters take down its article based on a blockbuster investigation into Appin Technology that had detailed its alleged targeting and spying on opposition leaders, corporate competitors, lawyers, and wealthy individuals on behalf of customers worldwide. Reuters “temporarily” removed its article in compliance with that injunction and is fighting the order in Indian court.

As Appin Training Centers has sought to enforce that same order against a slew of other news outlets, however, resistance is building. Earlier this week, the digital rights group the Electronic Frontier Foundation (EFF) sent a response—published here—pushing back against Appin Training Centers’ legal threats on behalf of media organizations caught in this crossfire, including the tech blog Techdirt and the investigative news nonprofit MuckRock.

No media outlet has claimed that Appin Training Centers—a group that describes itself as an educational firm run in part by former franchisees of the original Appin Technology, which reportedly ceased its alleged hacking operations more than a decade ago—has been involved in any illegal hacking. In December, however, Appin Training Centers sent emails to Techdirt and MuckRock demanding they too take down all content related to allegations that Appin Technology previously engaged in widespread cyberspying operations, citing the court order against Reuters.

Techdirt, Appin Training Centers argued, fell under that injunction by writing about Reuters’ story and the takedown order targeting it. So had MuckRock, the plaintiffs claimed, which hosted some of the documents that Reuters had cited in its story and uploaded to MuckRock’s DocumentCloud service. In the response sent on their behalf, the EFF states that the two media organizations are refusing to comply, arguing that the Indian court’s injunction “is in no way the global takedown order your correspondence represents it to be.” It also cites an American law called the SPEECH Act that deems any foreign court’s libel ruling that violates the First Amendment unenforceable in the US.

“It’s not a good state for a free press when one company can, around the world, disappear news articles,” Michael Morisy, the CEO and co-founder of MuckRock, tells WIRED. “That’s something that fundamentally we need to push back against.”

Techdirt founder Mike Masnick says that, beyond defeating the censorship of the Appin Technology story, he hopes their public response to that censorship effort will ultimately bring even more attention to the group’s past. In fact, 19 years ago, Masnick coined the term “the Streisand effect” to describe a situation in which someone’s attempt to hide information results in its broader exposure—exactly the situation he hopes to help create in this case. “The suppression of accurate reporting is problematic,” says Masnick. “When it happens, it deserves to be called out, and there should be more attention paid to those trying to silence it.”

The anti-secrecy nonprofit Distributed Denial of Secrets (DDoSecrets) has also joined the effort to spark that Streisand Effect, “uncensoring” Reuters’ story on the original Appin Technology as part of a new initiative it calls the Greenhouse Project. DDoSecrets cofounder Emma Best says the name comes from its intention to foster a “warming effect”—the opposite of the “chilling effect” used to describe the self-censorship created by legal threats. “It sends a signal to would-be censors, telling them that their success may be fleeting and limited,” Best says. “And it assures other journalists that their work can survive.”

Neither Appin Training Centers nor Rajat Khare responded to WIRED’s request for comment, nor did Reuters.

The fight to expose the original Appin Technology’s alleged hacking history began to reach a head in November of 2022, when the Association for Appin Training Centers sued Reuters based only on its reporters’ unsolicited messages to Appin Training Centers’ employees and students. The company’s legal complaint, filed in India’s judicial system, accused Reuters not only of defamation, but “mental harassment, stalking, sexual misconduct and trauma.”

Nearly a full year later, Reuters nonetheless published its article, “How an Indian Startup Hacked the World.” The judge in the case initially sided with Appin Training Centers, writing that the article could have a “devastating effect on the general students population of India.” He quickly ordered an injunction stating that Appin Training Centers can demand Reuters take down their claims about Appin Technology.

We keep making the same mistakes with spreadsheets, despite bad consequences

Science, spreadsheets, syndication / /

Not excelling at Excel —

Errors with spreadsheets are not only frustrating but can have serious consequences.

–

A dude being sad about his spreadhseet

Spreadsheet blunders aren’t just frustrating personal inconveniences. They can have serious consequences. And in the last few years alone, there have been a myriad of spreadsheet horror stories.

In August 2023, the Police Service of Northern Ireland apologized for a data leak of “monumental proportions” when a spreadsheet that contained statistics on the number of officers it had and their rank was shared online in response to a freedom of information request.

There was a second overlooked tab on the spreadsheet that contained the personal details of 10,000 serving police officers.

A series of spreadsheet errors disrupted the recruitment of trainee anesthetists in Wales in late 2021. The Anaesthetic National Recruitment Office (ANRO), the body responsible for their selection and recruitment, told all the candidates for positions in Wales they were “unappointable”, despite some of them achieving the highest interview scores.

The blame fell on the process of consolidating interview data. Spreadsheets from different areas lacked standardization in formatting, naming conventions, and overall structure. To make matters worse, data was manually copied and pasted between various spreadsheets, a time-consuming and error-prone process.

ANRO only discovered the blunder when rejected applicants questioned their dismissal letters. The fact that not a single candidate seemed acceptable for Welsh positions should have been a red flag. No testing or validation was apparently applied to the crucial spreadsheet, a simple step that could have prevented this critical error.

In 2021, Crypto.com, an online provider of cryptocurrency, accidentally transferred $10.5 million (£8.3 million) instead of $100 into the account of an Australian customer due to an incorrect number being entered on a spreadsheet.

The clerk who processed the refund for the Australian customer had wrongly entered her bank account number in the refund field in a spreadsheet. It was seven months before the mistake was spotted. The recipient attempted to flee to Malaysia but was stopped at an Australian airport carrying a large amount of cash.

In 2022, Íslandsbanki, a state-owned Icelandic bank, sold a portion of shares that were badly undervalued due to a spreadsheet error. When consolidating assets from different spreadsheets, the spreadsheet data was not “cleaned” and formatted properly. The bank’s shares were subsequently undervalued by as much as £16 million.

The dark matter of corporate IT

The above is just a fraction of the spreadsheet errors that are regularly made by various organizations.

Spreadsheets represent unknown risks in the form of errors, privacy violations, trade secrets, and compliance violations. Yet they are also critical for the way many organizations make their decisions. For this reason, they have been described by experts as the “dark matter” of corporate IT.

Industry studies show that 90 percent of spreadsheets containing more than 150 rows have at least one major mistake.

This is understandable because spreadsheet errors are easy to make but difficult to spot. My own research has shown that inspecting the spreadsheet’s code is the most effective way of debugging them, but this approach still only catches between 60 and 80 percent of all errors.

As many as 9 out of 10 spreadsheets are estimated to contain errors.

As many as 9 out of 10 spreadsheets are estimated to contain errors.

Spreadsheets’ appeal doesn’t just exist in the financial world. They are indispensable in engineering, data science, and even in sending robots to Mars. The key to their success is their flexibility.

Spreadsheet software is constantly evolving, with more features becoming available that increase their appeal. For instance, you can now automate many tasks in Excel (the most popular spreadsheet software) using Python scripting.

But given all of the aforementioned problems, isn’t it time for Excel and other spreadsheet software to be sidelined in favor of something more reliable?

Human error

The underlying cause of these spreadsheet problems is not the software but human error.

The issue is that most users don’t see the need to plan or test their work. Most users describe their first step in creating a new spreadsheet as merely jumping straight in and entering numbers or code directly.

Many of us don’t consider spreadsheets to warrant serious consideration. This means we become complacent and assume there is no need to test, validate, or verify our work.

Research on “cognitive load,” the amount of mental effort required for a task, shows that building complex spreadsheets demands as much concentration as a GP making a diagnosis. This intense mental strain makes mistakes more likely. But GPs study their profession for many years before becoming qualified, while most spreadsheet users are self-taught.

To break the cycle of repeated spreadsheet errors, there are several things organisations can do. First, introducing standardization would help to minimize confusion and mistakes. For example, this would mean consistent formatting, naming conventions, and data structures across spreadsheets.

Second, improving training is crucial. Equipping users with the knowledge and skills to build robust and accurate spreadsheets could help them identify and avoid pitfalls.

Finally, fostering a culture of critical thinking toward spreadsheets is vital. This would mean encouraging users to continually question calculations, validate their data sources, and double-check their work.

Air pollution from Canada’s tar sands is much worse than we thought

Canada’s tar sands have gained infamy for being one of the world’s most polluting sources of oil, thanks to the large amounts of energy and water use required for their extraction. A new study says the operations are also emitting far higher levels of a range of air pollutants than previously known, with implications for communities living nearby and far downwind.

The research, published Thursday in Science, took direct measurements of organic carbon emissions from aircraft flying above the tar sands, also called oil sands, and found levels that were 20 to 64 times higher than what companies were reporting. Total organic carbon includes a wide range of compounds, some of which can contribute directly to hazardous air pollution locally and others that can react in the atmosphere to form small particulate matter, or PM 2.5, a dangerous pollutant that can travel long distances and lodge deep in the lungs.

The study found that tar sands operations were releasing as much of these pollutants as all other human-made sources in Canada combined. For certain classes of heavy organic compounds, which are more likely to form particulates downwind, the concentrations were higher than what’s generally found in large metropolises like Los Angeles.

“The absolute magnitude of those emissions were a lot higher than what we expected,” said John Liggio, a research scientist at Environment and Climate Change Canada, the nation’s environmental regulatory agency, and a co-author on the study. Researchers at Yale University also contributed.

Seth Shonkoff, executive director of PSE Healthy Energy, an independent scientific research institute in California, who was not involved in the study, said the findings suggest air pollution from tar sands operations is more damaging to people’s health than previously known.

“I actually could hardly believe what I was reading,” Shonkoff said of the new study.

Over the last decade, a growing body of research has examined emissions of different air pollutants from oil and gas operations across the United States and Canada, and much of that has shown that industry estimates tend to undercount what’s being released, he said. “But the scale of this discrepancy is very surprising.”

Mark Cameron, vice president of external relations at the Pathways Alliance, an oil sands industry group, said in an email that the findings warrant further review and that “the oil sands industry measures emissions using standards set by Environment and Climate Change Canada and we look forward to working together to explore opportunities to further enhance our measurement practices.”

A law firm hired by the General Motors’ self-driving subsidiary Cruise to investigate the company’s response to a gruesome San Francisco crash last year found that the company failed to fully disclose disturbing details to regulators, the tech company said today in a blog post. The incident in October led California regulators to suspend Cruise’s license to operate driverless vehicles in San Francisco.

The new report by law firm Quinn Emanuel says that Cruise failed to tell California’s Department of Motor Vehicles that after striking a pedestrian knocked into its path by a human-driven vehicle, the autonomous car pulled out of traffic—dragging her some 20 feet. Cruise said it had accepted the firm’s version of events, as well as its recommendations.

The investigators found that when Cruise played a video of the crash taken from its autonomous vehicle for government officials, it did not “verbally point out” the vehicle’s pullover maneuver. Internet connectivity issues that occurred when the company tried to share video of the incident “likely precluded or hampered” regulators from seeing the full video, the report concluded.

Cruise executives are singled out in the report for failing to properly communicate with regulators. Company leaders assumed that regulators would ask questions that would lead the company to provide more information about the pedestrian dragging, the report says. And Cruise leadership is described as “fixated” on demonstrating to the media that it was a human-driven car, not its autonomous vehicle, that first struck the pedestrian. That “myopic focus,” the law firm concludes, led Cruise to “omit other important information” about the incident.

“The reasons for Cruise’s failings in this instance are numerous,” the law firm concluded, “poor leadership, mistakes in judgment, lack of coordination, an ‘us versus them’ mentality with regulators, and a fundamental misapprehension of Cruise’s obligations of accountability and transparency to the government and the public.” It said the company must take “decisive steps” to restore public trust.

Another third-party report on the crash released by Cruise today, by the engineering consulting firm Exponent, found that technical issues contributed to the autonomous vehicle’s dangerous pullover maneuver. Although the self-driving car’s software correctly detected, perceived, and tracked the pedestrian and the human-driven car, it classified the crash as a side-impact collision, which led it to pull over and drag the woman underneath it. Cruise says its technical issues were corrected when it recalled its software in November.

Cruise has paused its self-driving operations across the US since late October. Nine executives, plus CEO and cofounder Kyle Vogt, left in the fallout from the crash. In late 2023, the company laid off almost a quarter of its employees. General Motors says it will cut spending on the tech company by hundreds of millions of dollars this year compared to last.

Stablecoins, cryptocurrencies pegged to a stable value like the US dollar, were created with the promise of bringing the frictionless, border-crossing fluidity of bitcoin to a form of digital money with far less volatility. That combination has proved to be wildly popular, rocketing the total value of stablecoin transactions since 2022 past even that of Bitcoin itself.

It turns out, however, that as stablecoins have become popular among legitimate users over the past two years, they were even more popular among a different kind of user: those exploiting them for billions of dollars of international sanctions evasion and scams.

As part of its annual crime report, cryptocurrency-tracing firm Chainalysis today released new numbers on the disproportionate use of stablecoins for both of those massive categories of illicit crypto transactions over the last year. By analyzing blockchains, Chainalysis determined that stablecoins were used in fully 70 percent of crypto scam transactions in 2023, 83 percent of crypto payments to sanctioned countries like Iran and Russia, and 84 percent of crypto payments to specifically sanctioned individuals and companies. Those numbers far outstrip stablecoins’ growing overall use—including for legitimate purposes—which accounted for 59 percent of all cryptocurrency transaction volume in 2023.

In total, Chainalysis measured $40 billion in illicit stablecoin transactions in 2022 and 2023 combined. The largest single category of that stablecoin-enabled crime was sanctions evasion. In fact, across all cryptocurrencies, sanctions evasion accounted for more than half of the $24.2 billion in criminal transactions Chainalysis observed in 2023, with stablecoins representing the vast majority of those transactions.

The attraction of stablecoins for both sanctioned people and countries, argues Andrew Fierman, Chainalysis’ head of sanctions strategy, is that it allows targets of sanctions to circumvent any attempt to deny them a stable currency like the US dollar. “Whether it’s an individual located in Iran or a bad guy trying to launder money—either way, there’s a benefit to the stability of the US dollar that people are looking to obtain,” Fierman says. “If you’re in a jurisdiction where you don’t have access to the US dollar due to sanctions, stablecoins become an interesting play.”

As examples, Fierman points to Nobitex, the largest cryptocurrency exchange operating in the sanctioned country of Iran, as well as Garantex, a notorious exchange based in Russia that has been specifically sanctioned for its widespread criminal use. Stablecoin usage on Nobitex outstrips bitcoin by a 9:1 ratio, and on Garantex by a 5:1 ratio, Chainalysis found. That’s a stark difference from the roughly 1:1 ratio between stablecoins and bitcoins on a few nonsanctioned mainstream exchanges that Chainalysis checked for comparison.

As more companies ramp up development of artificial intelligence systems, they are increasingly turning to graphics processing unit (GPU) chips for the computing power they need to run large language models (LLMs) and to crunch data quickly at massive scale. Between video game processing and AI, demand for GPUs has never been higher, and chipmakers are rushing to bolster supply. In new findings released today, though, researchers are highlighting a vulnerability in multiple brands and models of mainstream GPUs—including Apple, Qualcomm, and AMD chips—that could allow an attacker to steal large quantities of data from a GPU’s memory.

The silicon industry has spent years refining the security of central processing units, or CPUs, so they don’t leak data in memory even when they are built to optimize for speed. However, since GPUs were designed for raw graphics processing power, they haven’t been architected to the same degree with data privacy as a priority. As generative AI and other machine learning applications expand the uses of these chips, though, researchers from New York-based security firm Trail of Bits say that vulnerabilities in GPUs are an increasingly urgent concern.

“There is a broader security concern about these GPUs not being as secure as they should be and leaking a significant amount of data,” Heidy Khlaaf, Trail of Bits’ engineering director for AI and machine learning assurance, tells WIRED. “We’re looking at anywhere from 5 megabytes to 180 megabytes. In the CPU world, even a bit is too much to reveal.”

To exploit the vulnerability, which the researchers call LeftoverLocals, attackers would need to already have established some amount of operating system access on a target’s device. Modern computers and servers are specifically designed to silo data so multiple users can share the same processing resources without being able to access each others’ data. But a LeftoverLocals attack breaks down these walls. Exploiting the vulnerability would allow a hacker to exfiltrate data they shouldn’t be able to access from the local memory of vulnerable GPUs, exposing whatever data happens to be there for the taking, which could include queries and responses generated by LLMs as well as the weights driving the response.

In their proof of concept, as seen in the GIF below, the researchers demonstrate an attack where a target—shown on the left—asks the open source LLM Llama.cpp to provide details about WIRED magazine. Within seconds, the attacker’s device—shown on the right—collects the majority of the response provided by the LLM by carrying out a LeftoverLocals attack on vulnerable GPU memory. The attack program the researchers created uses less than 10 lines of code.

An attacker (right) exploits the LeftoverLocals vulnerability to listen to LLM conversations.

Last summer, the researchers tested 11 chips from seven GPU makers and multiple corresponding programming frameworks. They found the LeftoverLocals vulnerability in GPUs from Apple, AMD, and Qualcomm and launched a far-reaching coordinated disclosure of the vulnerability in September in collaboration with the US-CERT Coordination Center and the Khronos Group, a standards body focused on 3D graphics, machine learning, and virtual and augmented reality.

The researchers did not find evidence that Nvidia, Intel, or Arm GPUs contain the LeftoverLocals vulnerability, but Apple, Qualcomm, and AMD all confirmed to WIRED that they are impacted. This means that well-known chips like the AMD Radeon RX 7900 XT and devices like Apple’s iPhone 12 Pro and M2 MacBook Air are vulnerable. The researchers did not find the flaw in the Imagination GPUs they tested, but others may be vulnerable.

Can water utilities meet the EPA’s new standard for PFAS?

Situated in a former sand and gravel pit just a few hundred feet from the Kennebec River in central Maine, the Riverside Station pumps half a million gallons of fresh groundwater every day. The well station processes water from two of five wells on either side of the river operated by the Greater Augusta Utility District, or GAUD, which supplies drinking water to nearly 6,000 local households. Most of them reside in Maine’s state capital, Augusta, just a few miles to the south. Ordinarily, GAUD prides itself on the quality of its water supply. “You could drink it out of the ground and be perfectly safe,” said Brian Tarbuck, GAUD’s general manager.

But in March 2021, environmental sampling of Riverside well water revealed trace levels of per- and polyfluoroalkyl substances (PFAS), or “forever chemicals,” as they’re better known. The levels at Riverside didn’t exceed Maine’s drinking water standard of 20 parts per trillion (ppt), which was a relief, Tarbuck said. Still, he and his colleagues at the utility were wary. PFAS have been linked to a variety of health problems, and Maine lawmakers at the time were debating an even stricter limit for the chemicals. Tarbuck knew a lower standard was coming someday. The only question was when.

As it turns out, a tougher standard is expected early this year. That’s when the US Environmental Protection Agency is set to finalize an enforceable cap on PFAS in drinking water that will require GAUD and thousands of other utilities around the country to update their treatment methods. The standard, which in regulatory terms is called a maximum contaminant level, or MCL, limits permissible amounts of the two most studied and ubiquitous PFAS compounds—PFOA and PFOS—to just 4 ppt in drinking water each. Roughly equivalent to a single drop in five Olympic-size swimming pools, this is the lowest concentration that current analytical instruments can reliably detect “within specific limits of precision and accuracy during routine laboratory operating conditions,” according to the EPA. Four other PFAS—PFHxS, PFNA, PFBS, and HFPO-DA (otherwise known as GenX Chemicals)—will be regulated by combining their acceptable levels into a single value. Utilities will have three to five years to bring their systems into compliance.

Agency officials estimate that between 3,400 and 6,300 water systems will be affected by the regulation, which is the EPA’s first ever PFAS standard and the first MCL set by the agency for any chemical in drinking water in over 25 years. PFOA and PFOS account for the majority of anticipated exceedances.

GAUD is now gearing up to spend $3 to 5 million on PFAS removal technology, according to Tarbuck, much of which will be passed on to its customers in the form of higher water bills. Nationally, the price tag of meeting the standard could top $37 billion in upfront costs, in addition to $650 million in annual operating expenses, according to the American Water Works Association, or AWWA, a nonprofit lobbying group representing water utilities. That’s far higher than the EPA’s cost estimate of $777 million to $1.2 billion and a significant burden for an industry already contending with other costly priorities, such as boosting cybersecurity and “replacing all those antiquated, leaking big water pipes that transport the water from the treatment plant to the service line” that connects to homes, said Marc Edwards, a professor of civil and environmental engineering at Virginia Tech. Chris Moody, the AWWA’s regulatory technical manager, said most of the money will be spent in the next several years, as utilities race to install PFAS removal systems and other infrastructure needed to meet compliance deadlines.

In proposing the limits, EPA officials said that they had leveraged the latest science to protect the public from PFAS pollution. Environmental groups welcomed the move as long overdue. But the standard has drawn widespread criticism from the water utility industry and some scientists who say that in many places, small drops in PFAS water levels will matter little for exposure or health. “There are other strategies that get us to safer, public health protective approaches to PFAS that don’t involve the really strict standard that EPA is putting forward,” said Ned Calonge, an associate dean for public health practice at the Colorado School of Public Health and chair of a 2022 National Academies of Sciences report on PFAS exposure, testing, and clinical follow-up.

EPA officials estimate that between 3,400 and 6,300 water systems will be affected by the regulation, which is the agency’s first-ever PFAS standard

A key issue, critics say, is that the standard ensnares too many utilities with very small PFAS exceedances. Roughly 98 percent of drinking water utilities in the country, including GAUD, have maximum PFOA and PFOS levels below 10 ppt, according to the AWWA. When the levels are already so low, further reductions of a few parts per trillion “is not going to have much effect on total exposure intake,” wrote Ian Cousins, an environmental chemist at Stockholm University and one of the world’s leading researchers on PFAS exposure, in an email to Undark.

Drinking water is only one among many different pathways by which people can be exposed to PFAS. The chemicals are also in agricultural produce, fish, meat, outdoor soil, household dust, nonstick cookware, cosmetics, fast-food wrappers, stain- and water-resistant fabrics, and other products. Just how much these sources each contribute to PFAS exposure is a subject of ongoing research. But the EPA estimates that Americans get 80 percent of their PFAS intake from sources other than drinking water, and according to Cousins, dietary contributions likely account for most human exposure. The US Food and Drug Administration has required the phase out of some PFAS in food packaging. But “food is contaminated via bioaccumulation in agricultural and marine food chains,” Cousins said. “We cannot clean up our food in the same way that we can add a treatment process to our drinking water.”

Child abusers are covering their tracks with better use of crypto

For those who trade in child sexual exploitation images and videos in the darkest recesses of the Internet, cryptocurrency has been both a powerful tool and a treacherous one. Bitcoin, for instance, has allowed denizens of that criminal underground to buy and sell their wares with no involvement from a bank or payment processor that might reveal their activities to law enforcement. But the public and surprisingly traceable transactions recorded in Bitcoin’s blockchain have sometimes led financial investigators directly to pedophiles’ doorsteps.

Now, after years of evolution in that grim cat-and-mouse game, new evidence suggests that online vendors of what was once commonly called “child porn” are learning to use cryptocurrency with significantly more skill and stealth—and that it’s helping them survive longer in the Internet’s most abusive industry.

Today, as part of an annual crime report, cryptocurrency tracing firm Chainalysis revealed new research that analyzed blockchains to measure the changing scale and sophistication of the cryptocurrency-based sale of child sexual abuse materials, or CSAM, over the past four years. Total revenue from CSAM sold for cryptocurrency has actually gone down since 2021, Chainalysis found, along with the number of new CSAM sellers accepting crypto. But the sophistication of crypto-based CSAM sales has been increasing. More and more, Chainalysis discovered, sellers of CSAM are using privacy tools like “mixers” and “privacy coins” that obfuscate their money trails across blockchains.

Perhaps because of that increased savvy, the company found that CSAM vendors active in 2023 persisted online—and evaded law enforcement—for a longer time than in any previous year, and about 57 percent longer than even in 2022. “Growing sophistication makes identification harder. It makes tracing harder, it makes prosecution harder, and it makes rescuing victims harder,” says Eric Jardine, the researcher who led the Chainalysis study. “So that sophistication dimension is probably the worst one you could see increasing over time.”

Better stealth, longer criminal lifespans

Scouring blockchains, Chainalysis researchers analyzed around 400 cryptocurrency wallets of CSAM sellers and more than 10,000 buyers who sent funds to them over the past four years. Their most disturbing finding in that broad economic study was that crypto-based CSAM sellers seem to have a longer lifespan online than ever, suggesting a kind of relative impunity. On average, CSAM vendors who were active in 2023 remained online for 884 days, compared with 560 days for those active in 2022 and just 112 days in 2020.

To explain that new longevity for some of the most harmful actors on the Internet, Chainalysis points to how CSAM vendors are increasingly laundering their proceeds with cryptocurrency mixers—services that blend users’ funds to make tracing more difficult—such as ChipMixer and Sinbad. (US and German law enforcement shut down ChipMixer in March 2023, but Sinbad remains online despite facing US sanctions for money laundering.) In 2023, Chainalysis found that about 46 percent of CSAM vendors used mixers, up from around 22 percent in 2020.

Chainalysis also found that CSAM vendors are increasingly using “instant exchanger” services that often collect little or no identifying information on traders and allow them to swap bitcoin for cryptocurrencies like Monero and Zcash—”privacy coins” designed to obfuscate or encrypt their blockchains to make tracing their cash-outs of profits far more difficult. Chainalysis’ Jardine says that Monero in particular seems to be gaining popularity among CSAM purveyors. In the company’s investigations, Chainalysis has seen it used repeatedly by CSAM sellers laundering funds through instant exchangers, and in multiple cases it has also seen CSAM forums post Monero addresses to solicit donations. While the instant exchangers did offer other cryptocurrencies, including the privacy coin Zcash, Chainalysis’ report states that “we believe Monero to be the currency of choice for laundering via instant exchangers.”
