Isaac Newton would never have discovered the laws of motion had he studied only cats.

Suppose you hold a cat, stomach up, and drop it from a second-story window. If a cat is simply a mechanical system that obeys Newton’s rules of matter in motion, it should land on its back. (OK, there are some technicalities—like this should be done in a vacuum, but ignore that for now.) Instead, most cats usually avoid injury by twisting themselves on the way down to land on their feet.

Most people are not mystified by this trick—everybody has seen videos attesting to cats’ acrobatic prowess. But for more than a century, scientists have wondered about the physics of how cats do it. Clearly, the mathematical theorem analyzing the falling cat as a mechanical system fails for live cats, as Nobel laureate Frank Wilczek points out in a recent paper.

“This theorem is not relevant to real biological cats,” writes Wilczek, a theoretical physicist at MIT. They are not closed mechanical systems, and can “consume stored energy … empowering mechanical motion.”

Nevertheless, the laws of physics do apply to cats—as well as every other kind of animal, from insects to elephants. Biology does not avoid physics; it embraces it. From friction on microscopic scales to fluid dynamics in water and air, animals exploit physical laws to run or swim or fly. Every other aspect of animal behavior, from breathing to building shelters, depends in some way on the restrictions imposed, and opportunities permitted, by physics.

“Living organisms are … systems whose actions are constrained by physics across multiple length scales and timescales,” Jennifer Rieser and coauthors write in the current issue of the Annual Review of Condensed Matter Physics.

While the field of animal behavior physics is still in its infancy, substantial progress has been made in explaining individual behaviors, along with how those behaviors are shaped via interactions with other individuals and the environment. Apart from discovering more about how animals perform their diverse repertoire of skills, such research may also lead to new physics knowledge gained by scrutinizing animal abilities that scientists don’t yet understand.

Critters in motion

Physics applies to animals in action over a wide range of spatial scales. At the smallest end of the range, attractive forces between nearby atoms facilitate the ability of geckos and some insects to climb up walls or even walk on ceilings. On a slightly larger scale, textures and structures provide adhesion for other biological gymnastics. In bird feathers, for instance, tiny hooks and barbs act like Velcro, holding feathers in position to enhance lift when flying, Rieser and colleagues report.

Biological textures also aid movement by facilitating friction between animal parts and surfaces. Scales on California king snakes possess textures that allow rapid forward sliding, but increase friction to retard backward or sideways motion. Some sidewinding snakes have apparently evolved different textures that reduce friction in the direction of motion, recent research suggests.

Small-scale structures are also important for animals’ interaction with water. For many animals, microstructures make the body “superhydrophobic”—capable of blocking the penetration of water. “In wet climates, water droplet shedding can be essential in animals, like flying birds and insects, where weight and stability are crucially important,” note Rieser, of Emory University, and coauthors Chantal Nguyen, Orit Peleg and Calvin Riiska.

Water-blocking surfaces also help animals keep their skins clean. “This self-cleansing mechanism … can be important to help protect the animal from dangers like skin-borne parasites and other infections,” the Annual Review authors explain. And in some cases, removing foreign material from an animal’s surface may be necessary to preserve the surface properties that enhance camouflage.

The surge is startling scientists, amplifying impacts such as hurricane storm surges.

JACKSONVILLE, Fla.—For most of his life, Steve Salem has led an existence closely linked with the rise and fall of the tides.

Salem is a 50-year boat captain who designed and built his 65-foot vessel by hand.

“Me and Noah, we’re related somewhere,” said Salem, 75, whose silver beard evokes Ernest Hemingway.

Salem is familiar with how the sun and moon influence the tides and feels an innate sense for their ebb and flow, although the tides here are beginning to test even his intuition.

He and his wife live in a rust-colored ranch-style house along a tributary of the St. Johns River, Florida’s longest. Before they moved in the house had flooded, in 2017, as Hurricane Irma swirled by. The house flooded again in 2022, when Hurricane Nicole defied his expectations. But Salem believes the house is sturdy and that he can manage the tides, as he always has.

“I’m a water dog to begin with. I’ve always been on the water,” said Salem, who prefers to go by Captain Steve. “I worry about things that I have to do something about. If I can’t do anything about it, then worrying about it is going to do what?”

Across the American South, tides are rising at accelerating rates that are among the most extreme on Earth, constituting a surge that has startled scientists such as Jeff Chanton, professor in the Department of Earth, Ocean and Atmospheric Science at Florida State University.

“It’s pretty shocking,” he said. “You would think it would increase gradually, it would be a gradual thing. But this is like a major shift.”

Worldwide sea levels have climbed since 1900 by some 1.5 millimeters a year, a pace that is unprecedented in at least 3,000 years and generally attributable to melting ice sheets and glaciers and also the expansion of the oceans as their temperatures warm. Since the middle of the 20th century the rate has gained speed, exceeding 3 millimeters a year since 1992.

In the South the pace has quickened further, jumping from about 1.7 millimeters a year at the turn of the 20th century to at least 8.4 millimeters by 2021, according to a 2023 study published in Nature Communications based on tidal gauge records from throughout the region. In Pensacola, a beachy community on the western side of the Florida Panhandle, the rate soared to roughly 11 millimeters a year by the end of 2021.

“I think people just really have no idea what is coming, because we have no way of visualizing that through our own personal experiences, or that of the last 250 years,” said Randall Parkinson, a coastal geologist at Florida International University. “It’s not something where you go, ‘I know what that might look like because I’ve seen that.’ Because we haven’t.

“It’s the same everywhere, from North Carolina all the way down to the Florida Keys and all the way up into Alabama,” he said. “All of these areas are extremely vulnerable.”

The acceleration is poised to amplify impacts such as hurricane storm surges, nuisance flooding and land loss. In recent years the rising tides have coincided with record-breaking hurricane seasons, pushing storm surges higher and farther inland. In 2022 Hurricane Ian, which came ashore in southwest Florida, was the costliest hurricane in state history and third-costliest to date in the United States, after Katrina in 2005 and Harvey in 2017.

“It doesn’t even take a major storm event anymore. You just get these compounding effects,” said Rachel Cleetus, a policy director at the Union for Concerned Scientists, an advocacy group. “All of a sudden you have a much more impactful flooding event, and a lot of the infrastructure, frankly, like the stormwater infrastructure, it’s just not built for this.”

New app releases for Apple Vision Pro have fallen dramatically since launch

Apple is struggling to attract fresh content for its innovative Vision Pro headset, with just a fraction of the apps available when compared with the number of developers created for the iPhone and iPad in their first few months.

The lack of a “killer app” to encourage customers to pay upwards of $3,500 for an unproven new product is seen as a problem for Apple, as the Vision Pro goes on sale in Europe on Friday.

Apple said recently that there were “more than 2,000” apps available for its “spatial computing” device, five months after it debuted in the US.

That compares with more than 20,000 iPad apps that had been created by mid-2010, a few months after the tablet first went on sale, and around 10,000 iPhone apps by the end of 2008, the year the App Store launched.

“The overall trajectory of the Vision Pro’s launch in February this year has been a lot slower than many hoped for,” said George Jijiashvili, analyst at market tracker Omdia.

“The reality is that most developers’ time and money will be dedicated to platforms with billions of users, rather than tens or hundreds of thousands.”

Apple believes the device will transform how millions work and play. The headset shifts between virtual reality, in which the wearer is immersed in a digital world, and a version of “augmented reality” that overlays images upon the real surroundings.

Omdia predicts that Apple will sell 350,000 Vision Pros this year. It forecasts an increase to 750,000 next year and 1.7 million in 2026, but the figures are far lower than the iPad, which sold almost 20 million units in its first year.

Estimates from IDC, a tech market researcher, suggest Apple shipped fewer than 100,000 units of Vision Pro in the first quarter, less than half what rival Meta sold of its Quest headsets.

Because of the device’s high price, Apple captured more than 50 percent of the total VR headset market by dollar value, IDC found, but analyst Francisco Jeronimo added: “The Vision Pro’s success, regardless of its price, will ultimately depend on the content available.”

Early data suggests that new content is arriving slowly. According to Appfigures, which tracks App Store listings, the number of new apps launched for the Vision Pro has fallen dramatically since January and February.

Nearly 300 of the top iPhone developers, whose apps are downloaded more than 10 million times a year—including Google, Meta, Tencent, Amazon, and Netflix—are yet to bring any of their software or services to Apple’s latest device.

Steve Lee, chief executive of AmazeVR, which offers immersive concert experiences, said that the recent launch of the device in China and elsewhere in Asia resulted in an uptick in downloads of his app. “However, it was about one-third of the initial launch in the United States.”

Lee remains confident that Vision Pro will eventually become a mainstream consumer product.

Wamsi Mohan, equity analyst at Bank of America, said the Vision Pro had “just not quite hit the imagination of the consumer.”

“This is one of the slower starts for a new Apple product category, just given the price point,” he said. “It seems management is emphasizing the success in enterprise a lot more.”

Nonetheless, some app developers are taking a leap of faith and launching on the Vision Pro. Some are betting that customers who can afford the pricey headset will be more likely to splurge on software, too.

Others are playing a longer game, hoping that establishing an early position on Apple’s newest platform will bring returns in the years to come.

gotta catch more —

The technologies are useful tools but have yet to move us away from fossil fuels.

–

Image of a facility filled with green-colored tubes.

Enlarge / Bioreactors that host algae would be one option for carbon sequestration—as long as the carbon is stored somehow.

More than 200 kilometers off Norway’s coast in the North Sea sits the world’s first offshore carbon capture and storage project. Built in 1996, the Sleipner project strips carbon dioxide from natural gas—largely made up of methane—to make it marketable. But instead of releasing the CO2 into the atmosphere, the greenhouse gas is buried.

The effort stores around 1 million metric tons of CO2 per year—and is praised by many as a pioneering success in global attempts to cut greenhouse gas emissions.

Last year, total global CO2 emissions hit an all-time high of around 35.8 billion tons, or gigatons. At these levels, scientists estimate, we have roughly six years left before we emit so much CO2 that global warming will consistently exceed 1.5° Celsius above average preindustrial temperatures, an internationally agreed-upon limit. (Notably, the global average temperature for the past 12 months has exceeded this threshold.)

Phasing out fossil fuels is key to cutting emissions and fighting climate change. But a suite of technologies collectively known as carbon capture, utilization and storage, or CCUS, are among the tools available to help meet global targets to cut CO2 emissions in half by 2030 and to reach net-zero emissions by 2050. These technologies capture, use or store away CO2 emitted by power generation or industrial processes, or suck it directly out of the air. The Intergovernmental Panel on Climate Change (IPCC), the United Nations body charged with assessing climate change science, includes carbon capture and storage among the actions needed to slash emissions and meet temperature targets.

Carbon capture, utilization and storage technologies often capture CO2 from coal or natural gas power generation or industrial processes, such as steel manufacturing. The CO2 is compressed into a liquid under high pressure and transported through pipelines to sites where it may be stored, in porous sedimentary rock formations containing saltwater, for example, or used for other purposes. The captured CO2 can be injected into the ground to extract oil dregs or used to produce cement and other products.

The captured CO2 can be injected into the ground to extract oil dregs or used to produce cement and other products.

Governments and industry are betting big on such projects. Last year, for example, the British government announced 20 billion pounds (more than $25 billion) in funding for CCUS, often shortened to CCS. The United States allocated more than $5 billion between 2011 and 2023 and committed an additional $8.2 billion from 2022 to 2026. Globally, public funding for CCUS projects rose to $20 billion in 2023, according to the International Energy Agency (IEA), which works with countries around the world to forge energy policy.

Given the urgency of the situation, many people argue that CCUS is necessary to move society toward climate goals. But critics don’t see the technology, in its current form, shifting the world away from oil and gas: In a lot of cases, they point out, the captured CO2 is used to extract more fossil fuels in a process known as enhanced oil recovery. They contend that other existing solutions such as renewable energy offer deeper and quicker CO2 emissions cuts. “It’s better not to emit in the first place,” says Grant Hauber, an energy finance adviser at the Institute for Energy Economics and Financial Analysis, a nonpartisan organization in Lakewood, Ohio.

What’s more, fossil fuel companies provide funds to universities and researchers—which some say could shape what is studied and what is not, even if the work of individual scientists is legitimate. For these reasons, some critics say CCUS shouldn’t be pursued at all.

“Carbon capture and storage essentially perpetuates fossil fuel reliance. It’s a distraction and a delay tactic,” says Jennie Stephens, a climate justice researcher at Northeastern University in Boston. She adds that there is little focus on understanding the psychological, social, economic, and political barriers that prevent communities from shifting away from fossil fuels and forging solutions to those obstacles.

According to the Global CCS Institute, an industry-led think tank headquartered in Melbourne, Australia, of the 41 commercial projects operational as of July 2023, most were part of efforts that produce, extract, or burn fossil fuels, such as coal- and gas-fired power plants. That’s true of the Sleipner project, run by the energy company Equinor. It’s the case, too, with the world’s largest CCUS facility, operated by ExxonMobil in Wyoming, in the United States, which also captures CO2 as part of the production of methane.

Granted, not all CCUS efforts further fossil fuel production, and many projects now in the works have the sole goal of capturing and locking up CO2. Still, some critics doubt whether these greener approaches could ever lock away enough CO2 to meaningfully contribute to climate mitigation, and they are concerned about the costs.

Others are more circumspect. Sally Benson, an energy researcher at Stanford University, doesn’t want to see CCUS used as an excuse to carry on with fossil fuels. But she says the technology is essential for capturing some of the CO2 from fossil fuel production and usage, as well as from industrial processes, as society transitions to new energy sources. “If we can get rid of those emissions with carbon capture and sequestration, that sounds like success to me,” says Benson, who codirects an institute that receives funding from fossil fuel companies.

In bid to loosen Nvidia’s grip on AI, AMD to buy Finnish startup for $665M

AMD is to buy Finnish artificial intelligence startup Silo AI for $665 million in one of the largest such takeovers in Europe as the US chipmaker seeks to expand its AI services to compete with market leader Nvidia.

California-based AMD said Silo’s 300-member team would use its software tools to build custom large language models (LLMs), the kind of AI technology that underpins chatbots such as OpenAI’s ChatGPT and Google’s Gemini. The all-cash acquisition is expected to close in the second half of this year, subject to regulatory approval.

“This agreement helps us both accelerate our customer engagements and deployments while also helping us accelerate our own AI tech stack,” Vamsi Boppana, senior vice president of AMD’s artificial intelligence group, told the Financial Times.

The acquisition is the largest of a privately held AI startup in Europe since Google acquired UK-based DeepMind for around 400 million pounds in 2014, according to data from Dealroom.

The deal comes at a time when buyouts by Silicon Valley companies have come under tougher scrutiny from regulators in Brussels and the UK. Europe-based AI startups, including Mistral, DeepL, and Helsing, have raised hundreds of millions of dollars this year as investors seek out a local champion to rival US-based OpenAI and Anthropic.

Helsinki-based Silo AI, which is among the largest private AI labs in Europe, offers tailored AI models and platforms to enterprise customers. The Finnish company launched an initiative last year to build LLMs in European languages, including Swedish, Icelandic, and Danish.

AMD’s AI technology competes with that of Nvidia, which has taken the lion’s share of the high-performance chip market. Nvidia’s success has propelled its valuation past $3 trillion this year as tech companies push to build the computing infrastructure needed to power the biggest AI models. AMD started to roll out its MI300 chips late last year in a direct challenge to Nvidia’s “Hopper” line of chips.

Peter Sarlin, Silo AI co-founder and chief executive, called the acquisition the “logical next step” as the Finnish group seeks to become a “flagship” AI company.

Silo AI is committed to “open source” AI models, which are available for free and can be customized by anyone. This distinguishes it from the likes of OpenAI and Google, which favor their own proprietary or “closed” models.

The startup previously described its family of open models, called “Poro,” as an important step toward “strengthening European digital sovereignty” and democratizing access to LLMs.

The concentration of the most powerful LLMs into the hands of a few US-based Big Tech companies is meanwhile attracting attention from antitrust regulators in Washington and Brussels.

The Silo deal shows AMD seeking to scale its business quickly and drive customer engagement with its own offering. AMD views Silo, which builds custom models for clients, as a link between its “foundational” AI software and the real-world applications of the technology.

Software has become a new battleground for semiconductor companies as they try to lock in customers to their hardware and generate more predictable revenues, outside the boom-and-bust chip sales cycle.

Nvidia’s success in the AI market stems from its multibillion-dollar investment in Cuda, its proprietary software that allows chips originally designed for processing computer graphics and video games to run a wider range of applications.

Since starting to develop Cuda in 2006, Nvidia has expanded its software platform to include a range of apps and services, largely aimed at corporate customers that lack the in-house resources and skills that Big Tech companies have to build on its technology.

Nvidia now offers more than 600 “pre-trained” models, meaning they are simpler for customers to deploy. The Santa Clara, California-based group last month started rolling out a “microservices” platform, called NIM, which promises to let developers build chatbots and AI “co-pilot” services quickly.

Historically, Nvidia has offered its software free of charge to buyers of its chips, but said this year that it planned to charge for products such as NIM.

AMD is among several companies contributing to the development of an OpenAI-led rival to Cuda, called Triton, which would let AI developers switch more easily between chip providers. Meta, Microsoft, and Intel have also worked on Triton.

the-president-ordered-a-board-to-probe-a-massive-russian-cyberattack-it-never-did.

The president ordered a board to probe a massive Russian cyberattack. It never did.

In this photo illustration, a Microsoft logo seen displayed on a smartphone with a Cyber Security illustration image in the background.

This story was originally published by ProPublica.

Investigating how the world’s largest software provider handles the security of its own ubiquitous products.

After Russian intelligence launched one of the most devastating cyber espionage attacks in history against US government agencies, the Biden administration set up a new board and tasked it to figure out what happened—and tell the public.

State hackers had infiltrated SolarWinds, an American software company that serves the US government and thousands of American companies. The intruders used malicious code and a flaw in a Microsoft product to steal intelligence from the National Nuclear Security Administration, National Institutes of Health, and the Treasury Department in what Microsoft President Brad Smith called “the largest and most sophisticated attack the world has ever seen.”

The president issued an executive order establishing the Cyber Safety Review Board in May 2021 and ordered it to start work by reviewing the SolarWinds attack.

But for reasons that experts say remain unclear, that never happened.

Nor did the board probe SolarWinds for its second report.

For its third, the board investigated a separate 2023 attack, in which Chinese state hackers exploited an array of Microsoft security shortcomings to access the email inboxes of top federal officials.

A full, public accounting of what happened in the Solar Winds case would have been devastating to Microsoft. ProPublica recently revealed that Microsoft had long known about—but refused to address—a flaw used in the hack. The tech company’s failure to act reflected a corporate culture that prioritized profit over security and left the US government vulnerable, a whistleblower said.

The board was created to help address the serious threat posed to the US economy and national security by sophisticated hackers who consistently penetrate government and corporate systems, making off with reams of sensitive intelligence, corporate secrets, or personal data.

For decades, the cybersecurity community has called for a cyber equivalent of the National Transportation Safety Board, the independent agency required by law to investigate and issue public reports on the causes and lessons learned from every major aviation accident, among other incidents. The NTSB is funded by Congress and staffed by experts who work outside of the industry and other government agencies. Its public hearings and reports spur industry change and action by regulators like the Federal Aviation Administration.

So far, the Cyber Safety Review Board has charted a different path.

The board is not independent—it’s housed in the Department of Homeland Security. Rob Silvers, the board chair, is a Homeland Security undersecretary. Its vice chair is a top security executive at Google. The board does not have full-time staff, subpoena power or dedicated funding.

Silvers told ProPublica that DHS decided the board didn’t need to do its own review of SolarWinds as directed by the White House because the attack had already been “closely studied” by the public and private sectors.

“We want to focus the board on reviews where there is a lot of insight left to be gleaned, a lot of lessons learned that can be drawn out through investigation,” he said.

As a result, there has been no public examination by the government of the unaddressed security issue at Microsoft that was exploited by the Russian hackers. None of the SolarWinds reports identified or interviewed the whistleblower who exposed problems inside Microsoft.

By declining to review SolarWinds, the board failed to discover the central role that Microsoft’s weak security culture played in the attack and to spur changes that could have mitigated or prevented the 2023 Chinese hack, cybersecurity experts and elected officials told ProPublica.

“It’s possible the most recent hack could have been prevented by real oversight,” Sen. Ron Wyden, a Democratic member of the Senate Select Committee on Intelligence, said in a statement. Wyden has called for the board to review SolarWinds and for the government to improve its cybersecurity defenses.

In a statement, a spokesperson for DHS rejected the idea that a SolarWinds review could have exposed Microsoft’s failings in time to stop or mitigate the Chinese state-based attack last summer. “The two incidents were quite different in that regard, and we do not believe a review of SolarWinds would have necessarily uncovered the gaps identified in the Board’s latest report,” they said.

The board’s other members declined to comment, referred inquiries to DHS or did not respond to ProPublica.

In past statements, Microsoft did not dispute the whistleblower’s account but emphasized its commitment to security. “Protecting customers is always our highest priority,” a spokesperson previously told ProPublica. “Our security response team takes all security issues seriously and gives every case due diligence with a thorough manual assessment, as well as cross-confirming with engineering and security partners.”

The board’s failure to probe SolarWinds also underscores a question critics including Wyden have raised about the board since its inception: whether a board with federal officials making up its majority can hold government agencies responsible for their role in failing to prevent cyberattacks.

“I remain deeply concerned that a key reason why the Board never looked at SolarWinds—as the President directed it to do so—was because it would have required the board to examine and document serious negligence by the US government,” Wyden said. Among his concerns is a government cyberdefense system that failed to detect the SolarWinds attack.

Silvers said while the board did not investigate SolarWinds, it has been given a pass by the independent Government Accountability Office, which said in an April study examining the implementation of the executive order that the board had fulfilled its mandate to conduct the review.

The GAO’s determination puzzled cybersecurity experts. “Rob Silvers has been declaring by fiat for a long time that the CSRB did its job regarding SolarWinds, but simply declaring something to be so doesn’t make it true,” said Tarah Wheeler, the CEO of Red Queen Dynamics, a cybersecurity firm, who co-authored a Harvard Kennedy School report outlining how a “cyber NTSB” should operate.

Silvers said the board’s first and second reports, while not probing SolarWinds, resulted in important government changes, such as new Federal Communications Commission rules related to cell phones.

“The tangible impacts of the board’s work to date speak for itself and in bearing out the wisdom of the choices of what the board has reviewed,” he said.

Alaska’s top-heavy glaciers are approaching an irreversible tipping point

meltdown —

As the plateau of the icefield thins, ice and snow reserves at higher altitudes are lost.

–

Taku Glacier is one of many that begin in the Juneau Icefield.

Enlarge / Taku Glacier is one of many that begin in the Juneau Icefield.

The melting of one of North America’s largest ice fields has accelerated and could soon reach an irreversible tipping point. That’s the conclusion of new research colleagues and I have published on the Juneau Icefield, which straddles the Alaska-Canada border near the Alaskan capital of Juneau.

In the summer of 2022, I skied across the flat, smooth, and white plateau of the icefield, accompanied by other researchers, sliding in the tracks of the person in front of me under a hot sun. From that plateau, around 40 huge, interconnected glaciers descend towards the sea, with hundreds of smaller glaciers on the mountain peaks all around.

Our work, now published in Nature Communications, has shown that Juneau is an example of a climate “feedback” in action: as temperatures are rising, less and less snow is remaining through the summer (technically: the “end-of-summer snowline” is rising). This in turn leads to ice being exposed to sunshine and higher temperatures, which means more melt, less snow, and so on.

Like many Alaskan glaciers, Juneau’s are top-heavy, with lots of ice and snow at high altitudes above the end-of-summer snowline. This previously sustained the glacier tongues lower down. But when the end-of-summer snowline does creep up to the top plateau, then suddenly a large amount of a top-heavy glacier will be newly exposed to melting.

That’s what’s happening now, each summer, and the glaciers are melting much faster than before, causing the icefield to get thinner and thinner and the plateau to get lower and lower. Once a threshold is passed, these feedbacks can accelerate melt and drive a self-perpetuating loss of snow and ice which would continue even if the world were to stop warming.

Ice is melting faster than ever

Using satellites, photos and old piles of rocks, we were able to measure the ice loss across Juneau Icefield from the end of the last “Little Ice Age” (about 250 years ago) to the present day. We saw that the glaciers began shrinking after that cold period ended in about 1770. This ice loss remained constant until about 1979, when it accelerated. It accelerated again in 2010, doubling the previous rate. Glaciers there shrank five times faster between 2015 and 2019 than from 1979 to 1990.

Our data shows that as the snow decreases and the summer melt season lengthens, the icefield is darkening. Fresh, white snow is very reflective, and much of that strong solar energy that we experienced in the summer of 2022 is reflected back into space. But the end of summer snowline is rising and is now often occurring right on the plateau of the Juneau Icefield, which means that older snow and glacier ice is being exposed to the sun. These slightly darker surfaces absorb more energy, increasing snow and ice melt.

As the plateau of the icefield thins, ice and snow reserves at higher altitudes are lost, and the surface of the plateau lowers. This will make it increasingly hard for the icefield to ever stabilise or even recover. That’s because warmer air at low elevations drives further melt, leading to an irreversible tipping point.

Longer-term data like these are critical to understand how glaciers behave, and the processes and tipping points that exist within individual glaciers. These complex processes make it difficult to predict how a glacier will behave in future.

The world’s hardest jigsaw

We used satellite records to reconstruct how big the glacier was and how it behaved, but this really limits us to the past 50 years. To go back further, we need different methods. To go back 250 years, we mapped the ridges of moraines, which are large piles of debris deposited at the glacier snout, and places where glaciers have scoured and polished the bedrock.

To check and build on our mapping, we spent two weeks on the icefield itself and two weeks in the rainforest below. We camped among the moraine ridges, suspending our food high in the air to keep it safe from bears, shouting to warn off the moose and bears as we bushwhacked through the rainforest, and battling mosquitoes thirsty for our blood.

We used aerial photographs to reconstruct the icefield in the 1940s and 1970s, in the era before readily available satellite imagery. These are high-quality photos but they were taken before global positioning systems made it easy to locate exactly where they were taken.

A number also had some minor damage in the intervening years—some Sellotape, a tear, a thumbprint. As a result, the individual images had to be stitched together to make a 3D picture of the whole icefield. It was all rather like doing the world’s hardest jigsaw puzzle.

Work like this is crucial as the world’s glaciers are melting fast—all together they are currently losing more mass than the Greenland or Antarctic ice sheets, and thinning rates of these glaciers worldwide has doubled over the past two decades.

Our longer time series shows just how stark this acceleration is. Understanding how and where “feedbacks” are making glaciers melt even faster is essential to make better predictions of future change in this important regionThe Conversation

To guard against cyberattacks in space, researchers ask “what if?”

If space systems such as GPS were hacked and knocked offline, much of the world would instantly be returned to the communications and navigation technologies of the 1950s. Yet space cybersecurity is largely invisible to the public at a time of heightened geopolitical tensions.

Cyberattacks on satellites have occurred since the 1980s, but the global wake-up alarm went off only a couple of years ago. An hour before Russia’s invasion of Ukraine on February 24, 2022, its government operatives hacked Viasat’s satellite-Internet services to cut off communications and create confusion in Ukraine.

I study ethics and emerging technologies and serve as an adviser to the US National Space Council. My colleagues and I at California Polytechnic State University’s Ethics + Emerging Sciences Group released a US National Science Foundation-funded report on June 17, 2024, to explain the problem of cyberattacks in space and help anticipate novel and surprising scenarios.

Space and you

Most people are unaware of the crucial role that space systems play in their daily lives, never mind military conflicts. For instance, GPS uses signals from satellites. GPS-enabled precision timing is essential in financial services where every detail—such as time of payment or withdrawal—needs to be faithfully captured and coordinated. Even making a mobile phone call relies on precise coordination of time in the network.

Besides navigation for airplanes, boats, cars, and people, GPS is also important for coordinating fleets of trucks that transport goods to stock local stores every day.

Earth-observation satellites are “eyes in the skies” with a unique vantage point to help forecast the weather, monitor environmental changes, track and respond to natural disasters, boost agricultural crop yields, manage land and water use, monitor troop movements, and much more. The loss of these and other space services could be fatal to people vulnerable to natural disasters and crop failure. They could also put global economics and security at serious risk.

Many satellites are crucial for tracking natural and human activity on Earth.

Factors in play

In our report, we identified several factors that contribute to the increasing threat of space cyberattacks. For instance, it’s important to recognize that the world is at the start of a new space race.

By all accounts, space is becoming more congested and more contested. Both nation-states and private companies, which are underregulated and now own most of the satellites in orbit, are gearing up to compete for resources and research sites.

Because space is so remote and hard to access, if someone wanted to attack a space system, they would likely need to do it through a cyberattack. Space systems are particularly attractive targets because their hardware cannot be easily upgraded once launched, and this insecurity worsens over time. As complex systems, they can have long supply chains, and more links in the chain increase the chance of vulnerabilities. Major space projects are also challenged to keep up with best practices over the decade or more needed to build them.

And the stakes are unusually high in space. Orbital trash zips around at speeds of 6 to 9 miles per second and can easily destroy a spacecraft on impact. It can also end space programs worldwide given the hypothesized Kessler syndrome in which the Earth is eventually imprisoned in a cocoon of debris. These consequences weigh in favor of space cyberattacks over physical attacks because the debris problem is also likely to affect the attacker.

Moreover, given critical space infrastructure and services, such as GPS, conflicts in space can spark or add more fuel to a conflict on Earth, even those in cyberspace. For instance, Russia warned in 2022 that hacking one of its satellites would be taken as a declaration of war, which was a dramatic escalation from previous norms around warfare.

the-dangers-of-sneezing—from-ejected-bowels-to-torn-windpipes

The dangers of sneezing—from ejected bowels to torn windpipes

health, Science, sneeze, sneezing, syndication / /

Autosomal Dominant Compelling Helioopthalmic Outburst (achoo) —

The benefits of a good sneeze can sometimes come with a greater risk of injury.

–

Picture shows a woman about to sneeze holding a handkerchief in her hand.

If you were to envision the kind of accident that would cause a person’s bowels to explode out of their body, you might imagine some sort of gruesome stabbing or grisly car accident. You’d probably never imagine that something as commonplace and harmless as a sneeze would cause this kind of ghastly injury—but that’s exactly what happened to a Florida man earlier this month.

The man had recently had abdominal surgery and was suffering from wound dehiscence—where his surgical scar wasn’t healing properly. While eating breakfast, the man first sneezed, then began coughing. He noticed pain and a wet sensation on his lower abdomen—only to discover several loops of his bowel had burst through his unhealed wound.

The man was rushed to hospital for emergency surgery where his bowels were returned to his abdomen.

Sneezing is normally a protective mechanism that keeps potentially harmful things—such as dust, bacteria and viruses – out of our respiratory system. The process is controlled by the so-called “sneezing center” in the brain’s medulla (which governs autonomic functions, including breathing). It’s activated by the presence of irritants in the lining of the nose and airways, which send impulses to the center.

The response is a closing of your eyes, throat and mouth while your chest muscles contract—compressing your lungs and driving air out of your respiratory system. This forces whatever triggered the response “out” of your system at an impressive speed—up to 15.9m/s (35mph) in some cases.

But despite the benefits of a good sneeze, it can sometimes come with a greater risk of injury than many might realize.

For instance, violent sneezing can cause the lung to herniate through the intercostal muscles between the ribs—usually at a point of weakness. This is typically a result of morbid obesity, chronic obstructive pulmonary disease, diabetes or smoking.

There are also cases of sneezing tearing the delicate tissues of the lungs. This happens when the higher pressure air deep in the lungs escapes into the space between the chest and the lung, causing this air to compress the lung on one or both sides of the chest.

The lungs aren’t the only thing that can tear. There are reports of people tearing the delicate lining of the brain from sneezing—leading to a subarachnoid haemorrhage (a type of stroke) which can be fatal if not diagnosed and treated promptly.

Even if you don’t tear this delicate lining, a sneeze can still affect the brain—with reports of people suffering weakness on one side of the body or visual disturbances following a sneeze.

Sneezing raises blood pressure which can cause other serious injuries to the blood vessels. There are cases of aortic dissection from sneezing, where the force of the sneeze tears the layers of the aorta (the major artery that carries oxygenated blood around the body) and causes blood to burst between the layers. If not treated, it has a 50 percent mortality rate within 48 hours of happening.

While it’s pretty common to injure your back while sneezing, this isn’t the only musculoskeletal injury that can happen. There are case reports of people fracturing the bones around their eye from sneezing. This type of fracture, called a blow-out fracture, is typically caused by blunt force trauma—often from a golf, tennis or baseball to the eye.

The small bones of the ear can fracture following a sneeze, which can cause hearing loss. Dental implants have been known to dislodge themselves into other parts of the face from a forceful sneeze.

The increased pressure caused by sneezing can cause fluid to escape from the body, particularly urine from the bladder. This is typically seen in people with weak pelvic floor muscles—usually caused by pregnancy, childbirth, obesity, menopause, and physical trauma or nerve damage.

Don’t hold it in

Given all the potential injuries a sneeze can cause, you might think it’s better to hold them in.

But even that isn’t safe to do. In 2023, a Scottish man held in a sneeze by closing his mouth and holding his nose. This resulted in him tearing his windpipe. By closing off his airways, this allowed the pressure generated by the sneeze to build up inside the respiratory system—which can sometimes be up to 20 times the pressure normally seen in the respiratory system. But this energy has to go somewhere, so is typically absorbed by the tissues.

Others have fractured bones of their face holding in sneezes, damaged their larynx (voice box), and torn the tissues in their chest that protect the lungs.

Thankfully, there is one injury that would be impossible for a sneeze to cause. Ever been told that if you sneeze with your eyes open, it’ll cause them to pop out? Thankfully, that’s just a tall tale. This is because your eyes are held in place by muscles and a nerve that anchors it in place. Not to mention that the airways in our respiratory system have no connection to your eyeballs or eye sockets.

Our body is well adapted to sneeze, so you probably don’t need to worry about suffering any injuries as many of these harms only happen in very rare circumstances. Though if you’re someone like Donna Griffiths (who has the longest recorded sneezing fit, lasting a nose-clearing 976 days) or Yi Yang (who has the loudest recorded sneeze at 176 decibels, the equivalent of a rocket taking flight), you may be at greater risk of harm.The Conversation

The hunt for the most efficient heat pump in the world

heat pumps, Science, syndication / /

beat the heat —

A new generation of engineers has realized they can push heat pumps to the limit.

–

Thermal imaging of two heat pumps and fan units, showing red and orange areas with elevated temperatures.

Outside a 100-year-old house on the edge of the Peak District in northern England, a heat pump’s fan blades are swiftly spinning. They’re drawing outdoor air over coils of refrigerant, harvesting warmth from that air. All air-source heat pumps do this—and they can glean heat even on cold days. But this heat pump is special. It is one of the most efficient installations of its kind in the country.

“I’m number two on there,” fizzes owner Rob Ritchie, a retired chemistry teacher, referring to the system’s position on HeatPumpMonitor.org, a kind of online leaderboard for heat pumps around the UK and beyond. “I should say it isn’t important—but it is. It’s nice being there.”

At the time of writing, real-time data suggests that for every kilowatt-hour of electricity Ritchie’s heat pump consumes, it delivers 5.5 kilowatt-hours of heat—a coefficient of performance, or COP, of 5.5. Achieving a COP of 5 or above is “absolutely incredible,” says Emma-Louise Bennett, active transition support lead at Viessmann, the company that made Ritchie’s heat pump. In the UK, average heat pump COPs tend to be between 2 and 3.

For social-media-savvy plumbers and environmentally conscious home renovators who are increasingly sharing videos of their heating systems online, heat pumps are in vogue. In the race to decarbonize and curtail the devastating effects of climate change, switching home heating systems away from fossil-fuel-burning boilers and furnaces is essential. Heat pumps will be a key weapon in that fight, says the International Energy Agency. It estimates that, globally, heat pumps could reduce CO2 emissions by 500 million metric tons—equivalent to taking every car in Europe off the road.

A new generation of heating engineers has realized that they can push heat pumps to the limit. These installers are reaching astounding levels of efficiency by taking extra care to design low-temperature heating systems that warm rooms without using excess energy.

Heat pumps can offer multiple kilowatt-hours of heat per kilowatt-hour of electricity, thanks to physics. The refrigerant sealed inside the device evaporates readily when it is warmed even slightly, say by the outdoor air, and a compressor then pressurizes the warmed gas, which has the effect of heating it further. It only takes a little electricity to power this process, which can raise the refrigerant’s temperature by many degrees Celsius.

Since moving to his detached house near Sheffield about 10 years ago, Ritchie has installed loft insulation and solar panels, but the fabric of the building is not necessarily ideal for keeping the place toasty in an efficient way. The property has thin-cavity walls without much insulation in them, and Ritchie lives at 800 feet above sea level, meaning outdoor temperatures are generally relatively low. Thanks to his heat pump and solar panels, though, he estimates he’s now saving 2,700 pounds ($3,420) on his utility bills annually. It goes to show that heat pumps can work well in older properties in challenging locations, he says.

The system was designed by local installer Damon Blakemore, who also checks HeatPumpMonitor.org regularly to see how his work stands up against that of his competitors. Ritchie’s heat pump is not quite in pole position at present, but it is noteworthy, emphasizes Blakemore, because once a year’s worth of data has accumulated this September, it could be the first air-source device on the leaderboard to achieve a 365-day seasonal COP, or SCOP, of 5. This is an average that reveals how well a heat pump has performed over an entire year. Weather changes between summer and winter, which shift demand for heating, tend to affect overall system efficiency, among other factors.

Blakemore is one of the “SCOP-chasers,” as Bennett puts it, driven to maximize the efficiency of the systems he installs. There is a small but highly visible group of such people in the UK who follow each other on Facebook and X, drop in on each other’s podcasts, and jostle for high rankings on HeatPumpMonitor.org. Among the stakeholders in this race for efficiency is Heat Geek, an organization that has trained multiple high-performing installers—including Blakemore.

“It’s not really something we particularly anticipated,” says Glyn Hudson, cofounder of Open Energy Monitor (OEM), which runs HeatPumpMonitor.org, referring to the casual competition emerging in the heating industry. “But installers are proud of their work. They do enjoy showing off photos of their installations on social media. The pipework layout is very important to them.”

Google’s greenhouse gas emissions jump 48% in five years

computationally intensive means energy intensive —

Google’s 2030 “Net zero” target looks increasingly doubtful as AI use soars.

Cooling pipes at a Google data center in Douglas County, Georgia.

Google’s greenhouse gas emissions have surged 48 percent in the past five years due to the expansion of its data centers that underpin artificial intelligence systems, leaving its commitment to get to “net zero” by 2030 in doubt.

The Silicon Valley company’s pollution amounted to 14.3 million tonnes of carbon equivalent in 2023, a 48 percent increase from its 2019 baseline and a 13 percent rise since last year, Google said in its annual environmental report on Tuesday.

Google said the jump highlighted “the challenge of reducing emissions” at the same time as it invests in the build-out of large language models and their associated applications and infrastructure, admitting that “the future environmental impact of AI” was “complex and difficult to predict.”

Chief Sustainability Officer Kate Brandt said the company remained committed to the 2030 target but stressed the “extremely ambitious” nature of the goal.

“We do still expect our emissions to continue to rise before dropping towards our goal,” said Brandt.

She added that Google was “working very hard” on reducing its emissions, including by signing deals for clean energy. There was also a “tremendous opportunity for climate solutions that are enabled by AI,” said Brandt.

As Big Tech giants including Google, Amazon, and Microsoft have outlined plans to invest tens of billions of dollars into AI, climate experts have raised concerns about the environmental impacts of the power-intensive tools and systems.

In May, Microsoft admitted that its emissions had risen by almost a third since 2020, in large part due to the construction of data centers. However, Microsoft co-founder Bill Gates last week also argued that AI would help propel climate solutions.

Meanwhile, energy generation and transmission constraints are already posing a challenge for the companies seeking to build out the new technology. Analysts at Bernstein said in June that AI would “double the rate of US electricity demand growth and total consumption could outstrip current supply in the next two years.”

In Tuesday’s report, Google said its 2023 energy-related emissions—which come primarily from data center electricity consumption—rose 37 percent year on year and overall represented a quarter of its total greenhouse gas emissions.

Google’s supply chain emissions—its largest chunk, representing 75 percent of its total emissions—also rose 8 percent. Google said they would “continue to rise in the near term” as a result in part of the build-out of the infrastructure needed to run AI systems.

Google has pledged to achieve net zero across its direct and indirect greenhouse gas emissions by 2030 and to run on carbon-free energy during every hour of every day within each grid it operates by the same date.

However, the company warned in Tuesday’s report that the “termination” of some clean energy projects during 2023 had pushed down the amount of renewables it had access to.

Meanwhile, the company’s data center electricity consumption had “outpaced” Google’s ability to bring more clean power projects online in the US and Asia-Pacific regions.

Google’s data center electricity consumption increased 17 percent in 2023, and amounted to approximately 7-10 percent of global data center electricity consumption, the company estimated. Its data centers also consumed 17 percent more water in 2023 than during the previous year, Google said.

Getting Fisked —

Build problems and unmet need for software updates have Fisker owners worried.

Fisker CEO Henrik Fisker introduces the all-electric compact hatchback Pear during its inaugural

Enlarge / Fisker CEO Henrik Fisker introduces the all-electric compact hatchback Pear during its inaugural “Product Vision Day” in Huntington Beach, California, on August 3, 2023.

It was the last week in June, and José De Bardi hadn’t gotten much sleep. The trouble had really kicked off on June 18, about a week earlier, when the electric vehicle company Fisker announced it had filed for bankruptcy protection. Now some 6,400 Fisker owners like De Bardi wondered: What will happen to their cars in the future?

The bankruptcy “lit a fire,” De Bardi says. “We had to get organized if we had any chance of representing owners’ interests.” Within days, he and a handful of other Fisker vehicle owners had established a nonprofit organization called the Fisker Owners Association, dedicated to keeping their cars running. (Hence, the lack of sleep.) By the end of the month, 1,200 owners—representing nearly a fifth of total Fisker cars sold—had registered through the group’s website, De Bardi says.

Fisker vehicle owners’ questions are mostly practical. Fisker began shipping the Ocean, its electric SUV—priced to start at $41,000 and ranging up to $70,0000—last year. Immediately, the vehicles were found to have serious build quality shortcomings and software issues, including a less-than-responsive central touchscreen. (WIRED’s reviewer declined to rate the vehicle entirely, calling it “just not ready yet.”)

Owners reported that some of the most serious issues, including a difficult-to-use brake hold and Bluetooth connectivity problems, were ironed out through software updates. But owners sometimes complained that it was tricky to get their vehicles serviced or repaired, because there weren’t enough certified Fisker repairers and technicians. Fisker initially launched with a Tesla-like “direct to consumer” model that eschewed the traditional “middleman” dealerships often seen in the US. But in January, the company began to sign dealerships to a new Fisker network, citing ballooning costs associated with the direct model.

Ownership woes

Even now, as the carcass of Fisker gets picked over, the EVs still have niggling problems—window cracks, dysfunctional key fobs, sudden connectivity blackouts—and will unquestionably need servicing and spare parts to keep them running into the future. Without Fisker, the company, to provide that, what are owners to do?

The FOA is still in the early stages of figuring it out. A small band of volunteers have worked around the clock to define the problems owners might face down the road—legal questions about their vehicle financing; issues with the car’s app; finding parts—and start solving them. These people have full-time jobs, too. De Bardi, for example, who lives in the UK and has headed up the European owners’ efforts, is also the CTO of a telecommunications firm.

Experts say Fisker owners’ situation is looking increasingly tricky. Automotive companies have a playbook to handle bankruptcies, developed during the 2008 financial crisis, which led General Motors and Chrysler to file for Chapter 11 protection, as Fisker has. Thanks in part to support from the US government, those automakers were able to honor their vehicles’ warranties as the companies restructured.

But in legal proceedings in Delaware this month, Fisker’s situation looked more dire. Lawyers for the firm’s creditors argued that Fisker should have filed for bankruptcy late last year. And Fisker plans to sell its remaining inventory, some 4,000 vehicles, to a firm that leases electric vehicles to New York City Uber and Lyft drivers, lawyers told the court.

If the company is forced to liquidate this way, owners may not be top of mind for the court and Fisker’s creditors, says John A.E. Pottow, a professor of law who studies bankruptcy at the University of Michigan Law School. The company may simply not have enough money to honor its vehicles’ warranties. “If Fisker is bankrupt, they have no obligation to update their software,” he says. And the company’s assets—its cars, their parts, and its intellectual property—may be too piddling to attract another firm to take up the mantle of service and repair. “Bankruptcy is never good,” Pottow says. “The smaller the business, the worse the issues.”

Right now, Fisker owners should make sure they have great comprehensive insurance on their cars, says Justin Simard, an associate professor of law researching commercial law at Michigan State University College of Law. Without a functioning service and repair system, “you could get totaled out with a little fender bender,” he says. The worst-case scenario might also see Ocean insurance rates increase and the cars’ resale values plummet even further, he says.

Fisker spokesperson Matthew Debord declined to comment on issues related to vehicle repair and parts manufacture, and referred WIRED to the company’s statements related to its Chapter 11 bankruptcy.

Fisker initially paused production of the Ocean in February, after warning investors it might not be able to see out the year. A month later, reported investment talks between the electric vehicle maker and Nissan collapsed, and the fate of Fisker became clearer. The automaker brought in some $273 million in revenue last year but lost $940 million and owes some $850 million to bondholders.

A handful of other electric vehicle makers, including Lordstown Motors, Arrival, and Volta Trucks, have also filed for bankruptcy amid a more-challenging-than-expected climate for electric vehicles and new vehicle development. A fleet maintenance firm agreed to provide service for Lordstown’s remaining fleet customers, while the assets of Arrival sold to another EV manufacturer, Canoo. Volta Trucks emerged from restructuring earlier this year with new ownership and says it will continue to manufacture vehicles.

Despite it all, José De Bardi, the Fisker Owners Association leader, says he wants to keep his black Fisker Ocean around for as long as he possibly can. “It’s now a fantastic car,” he says, acknowledging the EV’s initial “quirks.” Despite the challenges—and hard work—the group is feeling optimistic. “We’re feeling positive that we’re going to get some kind of good outcome,” he says.
