Nexperia, a Chinese Semiconductor manufacturing plant, located in the Netherlands, was seized by Dutch authorities last week in response to embargo pressures.
A Dutch seizure of Chinese-owned computer chip maker Nexperia came after rising U.S. pressure on the company, a court ruling released on Tuesday showed, underscoring how the firm has been caught in the crossfire between Washington and Beijing.
The government said on Sunday that it had intervened in Netherlands-based Nexperia, which makes chips for cars and consumer electronics. It cited worries about possible transfer of technology to its Chinese parent company, Wingtech.
[...] Nexperia is one of the largest makers globally of basic chips such as transistors that are not technically sophisticated but are needed in large volumes.
[...] The source said that company executives in the meeting believed that Dutch authorities were acquiescing to the United States and added that the company was very confident that it could have the decision reversed.
The Dutch government said on Tuesday there was no U.S. involvement or pressure in the decision to intervene in Nexperia.
Do you live in Australia and have an old module Samsung phone? If so, check your SMS messages as your phone may soon no longer work. Due to recent issues with triple zero and subsequent lawsuits Australian Telcos are blocking devices that cannot fallback to make calls on the national 000 number. Emergency Management Minister Kristy McBain has ruled out government assistance to Australians whose mobile phone may be unable to call triple-0. Devices affected by this block will no longer work after 26/11/2025.
The mobile devices affected by the issue are Galaxy A7 (2017), Galaxy A5 2017, Galaxy J1 2016j, Galaxy J3 2016, Galaxy J5 (2017), Galaxy S6, Galaxy S6 edge, Galaxy S6 Edge+, Galaxy S7 and Galaxy S7 Edge.
Ms McBain said the telecommunications companies were working to assess how many devices were impacted, but the number was estimated to be about 10,000.
[...] In a statement, TPG Telecom, which owns Vodafone, said it had identified a cohort of older Samsung handsets leading into the 3G network shutdown in 2024 that were unable to make triple-0 calls on the TPG/Vodafone mobile network and could not be fixed with a software upgrade.
"These devices were blocked from the Vodafone network as part of the 3G shutdown process," a spokesman said.
"Recently, we became aware that some of those same handsets that worked on other networks were unable to connect to triple-0 when only Vodafone coverage was available.
"These Samsung devices were found to be configured in way that permanently locked them to making triple-0 calls on the Vodafone 3G network even if being used with the SIM of another mobile operator and able to make triple-0 calls on their 4G network. This limitation was not previously known to TPG Telecom."
[...] An Optus spokesman earlier said during emergencies, and at times mobile phones could not connect to its regular network, phones were designed to search for another available network to reach triple-0.
"These situations relate to rare occasions when both the Optus and Telstra networks are unavailable and the phone needs to switch to Vodafone in order to contact emergency services," a spokesman said.
"This only happens under very specific conditions, but it's critically important that all devices can reach triple-0."
Is it the Year of the Linux Phone yet?
Cache Poisoning Vulnerabilities Found in 2 DNS Resolving Apps
The makers of BIND, the Internet's most widely used software for resolving domain names, are warning of two vulnerabilities that allow attackers to poison entire caches of results and send users to malicious destinations that are indistinguishable from the real ones.
The vulnerabilities, tracked as CVE-2025-40778 and CVE-2025-40780, stem from a logic error and a weakness in generating pseudo-random numbers, respectively. They each carry a severity rating of 8.6. Separately, makers of the Domain Name System resolver software Unbound warned of similar vulnerabilities that were reported by the same researchers. The unbound vulnerability severity score is 5.6
[...] In 2008, researcher Dan Kaminsky revealed one of the more severe Internet-wide security threats ever. Known as DNS cache poisoning, it made it possible for attackers to send users en masse to imposter sites instead of the real ones belonging to Google, Bank of America, or anyone else. With industry-wide coordination, thousands of DNS providers around the world—in coordination with makers of browsers and other client applications—implemented a fix that averted this doomsday scenario.
[...] What Kaminsky realized was that there were only 65,536 possible transaction IDs. An attacker could exploit this limitation by flooding a DNS resolver with lookup results for a specific domain. Each result would use a slight variation in the domain name, such as 1.arstechnica.com, 2.arstechnica.com, 3.arstechnica.com, and so on. Each result would also include a different transaction ID. Eventually, an attacker would reproduce the correct number of an outstanding request, and the malicious IP would get fed to all users who relied on the resolver that made the request. The attack was called DNS cache poisoning because it tainted the resolver's store of lookups.
[...] "Because exploitation is non-trivial, requires network-level spoofing and precise timing, and only affects cache integrity without server compromise, the vulnerability is considered Important rather than Critical," Red Hat wrote in its disclosure of CVE-2025-40780.
The vulnerabilities nonetheless have the potential to cause harm in some organizations. Patches for all three should be installed as soon as practicable.
It's Typhoon season...year round:
China's Salt Typhoon gang appears to have successfully attacked a European telecommunications firm, according to security researchers at Darktrace.
Salt Typhoon is an espionage gang linked to the People's Republic of China that hacked America's major telecommunications firms and stole metadata and other information belonging to "nearly every American," according to a top FBI cyber official who spoke with The Register about the intrusions.
The crew's actions against US telcos came to light last year; however, it has been active since at least 2019 using tactics including exploiting edge devices, planting backdoors for stealthy, long-term network access, and stealing sensitive data across more than 80 countries.
Today's Darktrace report is the latest indication that Salt Typhoon is still actively targeting high-value networks and using stealthy techniques to avoid being caught.
In the European telco intrusion described by Darktrace, the suspected spies exploited a buggy Citrix NetScaler Gateway appliance in the first week of July 2025 to gain access to the telecom's network, according to the AI-powered security shop's research team.
While Darktrace doesn't say which flaw(s) the suspected Chinese snoops abused to break in, Citrix had a busy summer patching security holes in its NetScaler Gateway products that had already been found and exploited by attackers.
"We didn't confirm which one," Nathaniel Jones, field CISO and VP of security and AI strategy at Darktrace, told The Register. "Given the timing, defenders were concurrently patching recent NetScaler flaws (e.g., CVE-2025-5349, CVE-2025-5777 in June)."
[...] After compromising the Citrix NetScaler appliance, the Salt Typhoon miscreants pivoted to Citrix Virtual Delivery Agent (VDA) hosts in the client's Machine Creation Services (MCS) subnet component. "Initial access activities in the intrusion originated from an endpoint potentially associated with the SoftEther VPN service, suggesting infrastructure obfuscation from the outset," Darktrace's threat hunters wrote in a Monday blog.
Next, the suspected spies deployed a backdoor to multiple Citrix VDA hosts. "The actor progressed to backdooring multiple Citrix VDA hosts with SNAPPYBEE (aka Deed RAT) and establishing C2 when Darktrace flagged it," Jones told us. "We feel confident it was remediated before the attack escalated. Thus, no dwell time."
Trend Micro researchers previously linked this modular backdoor to Salt Typhoon. Additionally, Darktrace says the intruders used DLL sideloading – also a favorite Salt Typhoon technique – to deliver the backdoor to these internal endpoints.
[...] "Based on overlaps in TTPs, staging patterns, infrastructure, and malware, Darktrace assesses with moderate confidence that the observed activity was consistent with Salt Typhoon/Earth Estries (ALA GhostEmperor/UNC2286)," the researchers wrote.
They also note that the vendor's security platform identified and stopped the intrusion "before escalating beyond these early stages of the attack."
Copilot now has its own virtual character for its voice mode:
It's been nearly 30 years since Microsoft's Office assistant, Clippy, first graced our screens as an annoying paperclip. After the Groucho-browed interruptions of Clippy came to an end in 2001 with Office XP, Microsoft tried to revive the spirit of an assistant with Cortana on Windows Phone. The technology still wasn't quite there a decade ago, but now Microsoft is ready to try again with Mico, a new character for Copilot's voice mode.
"Clippy walked so that we could run," jokes Jacob Andreou, corporate VP of product and growth at Microsoft AI, in an interview with The Verge. Microsoft has been testing Mico (rhymes with "pico") for a few months now, as a virtual character that responds with real-time expressions when you talk to it. Mico is now being turned on by default in Copilot's voice mode, where you'll also have the option to turn the bouncing orb off.
"You can see it, it reacts as you speak to it, and if you talk about something sad you'll see its facial expressions react almost immediately," explains Andreou. "All the technology fades into the background, and you just start talking to this cute orb and build this connection with it."
Mico will only be available in the US at launch, and this new Copilot virtual character will also rely on a new memory feature inside Copilot to be able to surface facts it has learned about you and the things you're working on.
Microsoft is also adding a Learn Live mode to Mico that will turn the character into a Socratic tutor that "guides you through concepts instead of just giving answers." It even uses interactive whiteboards and visual cues, and looks like it's targeted at students preparing for finals or anyone trying to practice a new language.
[...] Mico also forms a key part of Microsoft's new initiative to get people to talk to their computers. The software maker is running ads on TV marketing the latest Windows 11 PCs as "the computer you can talk to." Microsoft tried to convince people to use Cortana on Windows 10 PCs a decade ago, and that effort ended in the Cortana app being shut down on Windows 11 a couple of years ago.
Cast-off turbines generate up to 48 MW of electricity apiece:
Faced with multi-year delays to secure grid power, US data center operators are deploying aeroderivative gas turbines — effectively retired commercial aircraft engines bolted into trailers — to keep AI infrastructure online.
According to IEEE Spectrum, facilities in Texas are already spinning up units based on General Electric's CF6-80C2 and LM6000, the same turbine cores once found on 767s and Airbus A310s. Vendors like ProEnergy and Mitsubishi Power have turned these into modular, fast-start generators capable of delivering 48 megawatts apiece, enough to support a large AI cluster while utility-scale infrastructure lags.
Fast, loud, and anything but elegant, these "bridging power" units come from vendors like ProEnergy, which offers trailerized turbines built around ex-aviation cores that can spin up in minutes to meet energy demand. Meanwhile, Mitsubishi Power's FT8 MOBILEPAC, which derives from Pratt & Whitney jet engines, delivers a similar output in a self-contained footprint designed for fast deployment.
While this might not be the cheapest, and certainly not the cleanest, way to power racks, it's a viable stopgap for companies racing to hit AI milestones while local substations and modular nuclear power deployments remain years away.
[...] In one of the more visible examples, OpenAI's parent group is deploying nearly 30 LM2500XPRESS units at a facility near Abilene, Texas, as part of its multi-billion-dollar Stargate project. Each unit spins up to 34 megawatts, fast enough to cold-start servers in under ten minutes.

New method extracts desirable elements from waste magnets using less energy and acid:
All the world's discarded phones, bricked laptops, and other trashed electronics are collectively a treasure trove of rare earth elements (REEs). But separating out and recovering these increasingly sought-after materials is no easy task.
However, a team of researchers says it has developed a way of separating REEs from waste—magnets, in this case—that is relatively easy, uses less energy, and isn't nearly as emissions and pollution intensive as current methods. The team published a paper describing this method in the Proceedings of the National Academy of Sciences.
In short, this process involves using an electric current to heat waste magnets to very high temperatures very fast, and using chlorine gas to react with the non-REEs in the mix, keeping them in the vapor phase. James Tour, one of the authors and a professor of materials science and nanoengineering at Rice University, says that the research can help the United States meet its growing need for these elements.
"The country's scurrying to try to see how we can get these [REEs]," he says. "And, in our argument, it's all in our waste... We have it right here, just pull it right back out of the waste."
In 2018, Tour and his colleagues discovered that this rapid heating process, called flash joule heating, can turn any carbon source—including coal, biochar, and mixed plastic—into graphene, a very thin, strong, and conductive material.
Building on this, in 2023, they developed a method that uses flash joule heating and chlorine. In this work, they identified the Gibbs free energy, the reactivity of a material, for the oxide form of all 17 REEs and nine common oxides found in REE waste.
Ground-up waste magnets are put on a platform made of carbon and surrounded by a glass chamber. A current runs through the platform, rapidly producing immense heat, thousands of degrees celsius in a matter of seconds. Chlorine gas is then released into the chamber, creating chlorides of unwanted elements like iron and lowering their boiling points.
Between the chlorine gas and the heat, the non-REE components vaporize and form deposits on the interior of the chamber. The REEs are left behind in oxide or oxychloride form on the carbon platform, ready to be collected.
The team studied the differences in reactivity with chlorine gas and the difference of boiling points between the oxide and chloride forms of the metals—iron's boiling point is around 3,000° C, while iron chloride's boiling point is only 315° C—as they "probed around" and tested different voltages and temperatures on neodymium-iron-boron and samarium-cobalt magnet waste.
Because magnets are hard, they were heated to 800° C to demagnetize and soften them prior to grinding them to dust. The separated REE residue at the end of the process can be remagnetized by exposing them to a magnet.
The end result is more than 90 percent pure and recovers more than 90 percent of the REEs from the waste magnets. Tour adds that the method could be used on different forms of e-waste, not just magnets.
Tour and his colleagues also ran a life cycle assessment and techno-economic analysis, comparing their method to a common method of recovering REEs from waste. Called hydrometallurgical extraction, it requires a fair amount of energy and the use of a lot of acids and solvents. "It's a messy, messy process," he says.
The team's analysis suggests that the method involving Fast Joule Heating and chlorine gas reduces energy consumption, greenhouse gas emission, and operating costs by 87, 84, and 54 percent, respectively.
In 2022 alone, the world produced 66.2 million tonnes of this e-waste. Metal, unlike plastic, is infinitely recyclable, and the concentration of REEs in e-waste is much higher than occurs naturally. The two main ways of mining REEs both release toxic chemicals into surrounding environments. Setting up a mine is also very expensive, Tour adds.
"You might as well just get it from waste."

Latvian police bust European cybercrime ring and arrest seven suspects:
Latvian police have busted a major internet fraud network that has scammed thousands of victims across Europe.
Police arrested seven suspects, the EU's law enforcement agency Europol said on Friday.
To dismantle the criminal ring, law enforcement investigators from Austria, Estonia and Latvia, in partnership with the EU agencies Europol and Eurojust, teamed up.
The probe culminated in an operation that took place on 10 October.
The detained suspects are believed to be responsible for more than 1,700 individual cyberfraud cases in Austria and 1,500 in Latvia.
They are accused of having scammed victims out of nearly €5 million, of which €4.5 million were in Austria and €420,000 in Latvia.
As part of the operation, which was dubbed SIMCARTEL, police seized 1,200 SIM box devices and 40,000 active SIM cards, Europol said.
"Other offences facilitated by this criminal service include fraud, extortion, migrant smuggling and the distribution of child sexual abuse material," Europol wrote in a statement.
"I'm about to just toss the whole thing...":
Amazon Echo Show owners are reporting an uptick in advertisements on their smart displays.
The company's Echo Show smart displays have previously shown ads through the company's Shopping Lists feature, as well as advertising for Alexa skills. Additionally, Echo Shows may play audio ads when users listen to Amazon Music on Alexa.
However, reports on Reddit (examples here, here, and here) and from The Verge's Jennifer Pattison Tuohy, who owns more than one Echo Show, suggest that Amazon has increased the amount of ads it shows on its smart displays' home screens. The Echo Show's apparent increase in ads is pushing people to stop using or even return their Echo Shows.
The smart displays have also started showing ads for Alexa+, the new generative AI version of Amazon's Alexa voice assistant. Ads for the subscription-based Alexa+ are reportedly taking over Echo Show screens, even though the service is still in Early Access.
"This is getting ridiculous and I'm about to just toss the whole thing and move back to Google," one Redditor said of the "full-volume" ads for Alexa+ on their Echo Show.
[...] Amazon's Devices business famously doesn't make money, so it's not too surprising to see the company's smart displays resort to ads, something Amazon is making money on.
Expanding on its ads program for Alexa devices, which launched in 2023, Amazon ramped up efforts to sell customers' Echo Show screen space to advertisers in July when it launched a program for showing home screen ads on devices using Alexa+. Amazon recently said it may also put ads into Alexa+ conversations.
[...] After Amazon's devices launch last month, we noted that Alexa's survival hinges on users' tolerance for pricier Amazon devices. It seems people's tolerance for ads will also play a role.
WindBorne says its balloons are compliant with all applicable airspace regulations:
The mysterious impact of a United Airlines aircraft in flight last week has sparked plenty of theories as to its cause, from space debris to high-flying birds.
However the question of what happened to flight 1093, and its severely damaged front window, appears to be answered in the form of a weather balloon.
"I think this was a WindBorne balloon," Kai Marshland, co-founder of the weather prediction company WindBorne Systems, told Ars in an email on Monday evening. "We learned about UA1093 and the potential that it was related to one of our balloons at 11 pm PT on Sunday and immediately looked into it. At 6 am PT, we sent our preliminary investigation to both NTSB and FAA, and are working with both of them to investigate further."
WindBorne is a six-year old company that seeks to both collect weather observations with its fleet of small, affordable weather balloons as well as use that atmospheric data for its proprietary artificial intelligence weather models.
Scott Manley, a popular YouTube creator and pilot, was among the first people to speculate online about the collision being caused by a WindBorne balloon, having coordinated the position of a balloon data point with the flight path of the aircraft. Asked about this by Ars, the company confirmed that its balloon likely hit the plane.
The strike occurred Thursday, during a United Airlines flight from Denver to Los Angeles. Images shared on social media showed that one of the two large windows at the front of a 737 MAX aircraft was significantly cracked. Related images also reveal a pilot's arm that has been cut multiple times by what appear to be small shards of glass.
Speculation built over the weekend after one of the aircraft's pilots described the object that impacted the aircraft as "space debris." On Sunday the National Transportation Safety Board confirmed that it is investigating the collision, which did not cause any fatalities. However, one of the pilot's arms appeared to be cut up by small shards of glass from the windshield.
WindBorne has a fleet of global sounding balloons that fly various vertical profiles around the world, gathering atmospheric data. Each balloon is fairly small, with a mass of 2.6 pounds (1.2 kg), and provides temperature, wind, pressure, and other data about the atmosphere. Such data is useful for establishing initial conditions upon which weather models base their outputs.
Notably, the company has an FAQ on its website (which clearly was written months or years ago, before this incident) that addresses several questions, including: Why don't WindBorne balloons pose a risk to airplanes?
"The quick answer is our constellation of Global Sounding Balloons (GSBs), which we call WindBorne Atlas, doesn't pose a threat to airplanes or other objects in the sky. It's not only highly improbable that a WindBorne balloon could even collide with an aircraft in the first place; but our balloons are so lightweight that they would not cause significant damage.
WindBorne also said that its balloons are compliant with all applicable airspace regulations.
"For example, we maintain active lines of communication with the FAA to ensure our operations satisfy all relevant regulatory requirements," the company states. "We also provide government partners with direct access to our comprehensive, real-time balloon tracking system via our proprietary software, WindBorne Live."
It started with a now-deleted tweet from OpenAI manager Kevin Weil, who wrote that GPT-5 had "found solutions to 10 (!) previously unsolved Erdős problems" and made progress on eleven more. He described these problems as "open for decades." Other OpenAI researchers echoed the claim.
The wording made it sound like GPT-5 had independently produced mathematical proofs for tough number theory questions - a potential scientific breakthrough and a sign that generative AI could uncover unknown solutions, showing its ability to drive novel research and open the door to major advances.
Mathematician Thomas Bloom, who runs erdosproblems.com, pushed back right away. He called the statements "a dramatic misinterpretation," clarifying that "open" on his site just means he personally doesn't know the solution - not that the problem is actually unsolved. GPT-5 had only surfaced existing research that Bloom had missed.
Deepmind-CEO Demis Hassabis called the episode "embarrassing", and Meta AI chief Yann LeCun pointed out that OpenAI had basically bought into its own hype ("Hoisted by their own GPTards").
The original tweets were mostly deleted, and the researchers admitted their mistake. Still, the incident adds to the perception that OpenAI is an organization under pressure and careless in its approach. It raises questions about why leading AI researchers would share such dramatic claims without verifying the facts, especially in a field already awash in hype, with billions at stake. Bubeck knew what GPT-5 actually contributed, but still used the ambiguous phrase "found solutions."
The real story here is getting overshadowed: GPT-5 actually proved useful as a research tool for tracking down relevant academic papers. This is especially valuable for problems where the literature is scattered or the terminology isn't consistent.
Mathematician Terence Tao sees this as the most immediate potential for AI in math—not solving the toughest open problems, but speeding up tedious tasks like literature searches. While there have been some "isolated examples of progress" on difficult questions, Tao says AI is most valuable as a time-saving assistant. He has also said that generative AI could help "industrialize" mathematics and accelerate progress in the field. Still, human expertise is crucial for reviewing, classifying, and safely integrating AI-generated results into real research.
Too many services depend not just on one cloud provider, but on one location:
Analysis Amazon's US-EAST-1 region outage caused widespread chaos, taking websites and services offline even in Europe and raising some difficult questions. After all, cloud operations are supposed to have some built-in resiliency, right?
The problems began just after midnight US Pacific Time today when Amazon Web Services (AWS) noticed increased error rates and latencies for multiple services running within its home US-EAST-1 region.
Within a couple of hours, Amazon's techies had identified DNS as a potential root cause of the issue – specifically the resolution of the DynamoDB API endpoint in US-EAST-1 – and were working on a fix.
However, it was affecting other AWS services, including global services and or features that rely on endpoints operating from AWS' original region, such as IAM (Identity and Access Management) updates and DynamoDB global tables.
While Amazon worked to fully resolve the problem, the issue was already causing widespread chaos to websites and online services beyond the Northern Virginia locale of US-EAST-1, and even outside of America's borders.
As The Register reported earlier, Amazon.com itself was down for a time, while the company's Alexa smart speakers and Ring doorbells stopped working. But the effects were also felt by messaging apps such as Signal and WhatsApp, while in the UK, Lloyds Bank and even government services such as tax agency HMRC were impacted.
According to a BBC report, outage monitor Downdetector indicated there had been more than 6.5 million reports globally, with upwards of 1,000 companies affected.
How could this happen? Amazon has a global footprint, and its infrastructure is split into regions, physical locations with a cluster of datacenters. Each region consists of a minimum of three isolated and physically separate availability zones (AZ), each with independent power and connected via redundant, ultra-low-latency networks.
Customers are encouraged to design their applications and services to run in multiple AZs to avoid being taken down by a failure in one of them.
Sadly, it seems that the entire edifice has an Achilles heel that can cause problems regardless of how much redundancy you design into your cloud-based operations, at least according to the experts we asked.
"The issue with AWS is that US East is the home of the common control plane for all of AWS locations except the federal government and European Sovereign Cloud. There was an issue some years ago when the problem was related to management of S3 policies that was felt globally," Omdia Chief Analyst Roy Illsley told us.
He explained that US-EAST-1 can cause global issues because many users and services default to using it since it was the first AWS region, even if they are in a different part of the world.
Certain "global" AWS services or features are run from US-EAST-1 and are dependent on its endpoints, and this includes DynamoDB Global Tables and the Amazon CloudFront content delivery network (CDN), Illsley added.
Sid Nag, president and chief research officer for Tekonyx, agreed.
"Although the impacted region is in the AWS US East region, many global services (including those used in Europe) depend on infrastructure or control-plane / cross-region features located in US-EAST-1. This means that even if the European region was unaffected in terms of its own availability zones, dependencies could still cause knock-on impact," he said.
"Some AWS features (for example global account-management, IAM, some control APIs, or even replication endpoints) are served from US-EAST-1, even if you're running workloads in Europe. If those services go down or become very slow, even European workloads may be impacted," he added.
Any organization whose resiliency plans extend to duplicating resources across two or more different cloud platforms will no doubt be feeling smug right now, but that level of redundancy costs money, and don't the cloud providers keep telling us how reliable they are?
The upshot of this is that many firms will likely be taking another look at the assumptions underpinning their cloud strategy.
"Today's massive AWS outage is a visceral reminder of the risks of over-reliance on two dominant cloud providers, an outage most of us will have felt in some way," said Nicky Stewart, Senior Advisor at the Open Cloud Coalition.
Cloud services in the UK are largely dominated by AWS and Microsoft's Azure, with Google Cloud coming a distant third.
"It's too soon to gauge the economic fallout, but for context, last year's global CrowdStrike outage was estimated to have cost the UK economy between £1.7 and £2.3 billion ($2.3 and $3.1 billion). Incidents like this make clear the need for a more open, competitive and interoperable cloud market; one where no single provider can bring so much of our digital world to a standstill," she added.
"The AWS outage is yet another reminder of the weakness of centralised systems. When a key component of internet infrastructure depends on a single US cloud provider, a single fault can bring global services to their knees - from banks to social media, and of course the likes of Signal, Slack and Zoom," said Amandine Le Pape, Co-Founder of Element, which provides sovereign and resilient communications for governments.
But there could also be compensation claims in the offing, especially where financial transactions may have failed or missed deadlines because of the incident.
"An outage such as this can certainly open the provider and its users to risk of loss, especially businesses that rely on its infrastructure to operate critical services," said Henna Elahi, Senior Associate at Grosvenor Law.
Elahi added that it would, of course, depend on factors, such as the terms of service and any service level agreements between the business and AWS, the specific causes of the outage and its severity and length.
"The impacts on Lloyds Bank, for example, could have very serious implications for the end user. Key payments and transfers that are being made may fail and this could lead to far reaching issues for a user such as causing breaches of contracts, failure to complete purchases and failure to provide security information. This may very well lead to customer complaints and attempts to recover any loss caused by the outage from the business," she said.
At 15.13 UTC today, AWS updated its Health Dashboard:
"We have narrowed down the source of the network connectivity issues that impacted AWS Services. The root cause is an underlying internal subsystem responsible for monitoring the health of our network load balancers. We are throttling requests for new EC2 instance launches to aid recovery and actively working on mitigations."
Thirty minutes later, it added:
"We have taken additional mitigation steps to aid the recovery of the underlying internal subsystem responsible for monitoring the health of our network load balancers and are now seeing connectivity and API recovery for AWS services. We have also identified and are applying next steps to mitigate throttling of new EC2 instance launches."
Water bound in mantle rock alters our view of the Earth's composition:
Researchers from Northwestern University and the University of New Mexico report evidence for potentially oceans worth of water deep beneath the United States. Though not in the familiar liquid form — the ingredients for water are bound up in rock deep in the Earth's mantle — the discovery may represent the planet's largest water reservoir.
The presence of liquid water on the surface is what makes our "blue planet" habitable, and scientists have long been trying to figure out just how much water may be cycling between Earth's surface and interior reservoirs through plate tectonics.
Northwestern geophysicist Steve Jacobsen and University of New Mexico seismologist Brandon Schmandt have found deep pockets of magma located about 400 miles beneath North America, a likely signature of the presence of water at these depths. The discovery suggests water from the Earth's surface can be driven to such great depths by plate tectonics, eventually causing partial melting of the rocks found deep in the mantle.
The findings, to be published June 13 in the journal Science, will aid scientists in understanding how the Earth formed, what its current composition and inner workings are and how much water is trapped in mantle rock.
"Geological processes on the Earth's surface, such as earthquakes or erupting volcanoes, are an expression of what is going on inside the Earth, out of our sight," said Jacobsen, a co-author of the paper. "I think we are finally seeing evidence for a whole-Earth water cycle, which may help explain the vast amount of liquid water on the surface of our habitable planet. Scientists have been looking for this missing deep water for decades."
A blue crystal of ringwoodite containing around one percent of H2O in its crystal structure is compressed to conditions of 700 km depth inside a diamond-anvil cell. Using a laser to heat the sample to temperatures over 1500C (orange spots), the ringwoodite transformed to minerals found in the lowermost mantle. Synchrotron-infrared spectra collected on beamline U2A at the NSLS reveal changes in the OH-absorption spectra that correspond to melt generation, which was also detected by seismic waves underneath most of North America.
Scientists have long speculated that water is trapped in a rocky layer of the Earth's mantle located between the lower mantle and upper mantle, at depths between 250 miles and 410 miles. Jacobsen and Schmandt are the first to provide direct evidence that there may be water in this area of the mantle, known as the "transition zone," on a regional scale. The region extends across most of the interior of the United States.
Schmandt, an assistant professor of geophysics at the University of New Mexico, uses seismic waves from earthquakes to investigate the structure of the deep crust and mantle. Jacobsen, an associate professor of Earth and planetary sciences at Northwestern's Weinberg College of Arts and Sciences, uses observations in the laboratory to make predictions about geophysical processes occurring far beyond our direct observation.
The study combined Jacobsen's lab experiments in which he studies mantle rock under the simulated high pressures of 400 miles below the Earth's surface with Schmandt's observations using vast amounts of seismic data from the USArray, a dense network of more than 2,000 seismometers across the United States.
Jacobsen's and Schmandt's findings converged to produce evidence that melting may occur about 400 miles deep in the Earth. H2O stored in mantle rocks, such as those containing the mineral ringwoodite, likely is the key to the process, the researchers said.
"Melting of rock at this depth is remarkable because most melting in the mantle occurs much shallower, in the upper 50 miles," said Schmandt, a co-author of the paper. "If there is a substantial amount of H2O in the transition zone, then some melting should take place in areas where there is flow into the lower mantle, and that is consistent with what we found."
If just one percent of the weight of mantle rock located in the transition zone is H2O, that would be equivalent to nearly three times the amount of water in our oceans, the researchers said.
This water is not in a form familiar to us — it is not liquid, ice or vapor. This fourth form is water trapped inside the molecular structure of the minerals in the mantle rock. The weight of 250 miles of solid rock creates such high pressure, along with temperatures above 2,000 degrees Fahrenheit, that a water molecule splits to form a hydroxyl radical (OH), which can be bound into a mineral's crystal structure.
Schmandt and Jacobsen's findings build on a discovery reported in March in the journal Nature in which scientists discovered a piece of the mineral ringwoodite inside a diamond brought up from a depth of 400 miles by a volcano in Brazil. That tiny piece of ringwoodite — the only sample in existence from within the Earth — contained a surprising amount of water bound in solid form in the mineral.
"Whether or not this unique sample is representative of the Earth's interior composition is not known, however," Jacobsen said. "Now we have found evidence for extensive melting beneath North America at the same depths corresponding to the dehydration of ringwoodite, which is exactly what has been happening in my experiments."
For years, Jacobsen has been synthesizing ringwoodite, colored sapphire-like blue, in his Northwestern lab by reacting the green mineral olivine with water at high-pressure conditions. (The Earth's upper mantle is rich in olivine.) He found that more than one percent of the weight of the ringwoodite's crystal structure can consist of water — roughly the same amount of water as was found in the sample reported in the Nature paper.
"The ringwoodite is like a sponge, soaking up water," Jacobsen said. "There is something very special about the crystal structure of ringwoodite that allows it to attract hydrogen and trap water. This mineral can contain a lot of water under conditions of the deep mantle."
For the study reported in Science, Jacobsen subjected his synthesized ringwoodite to conditions around 400 miles below the Earth's surface and found it forms small amounts of partial melt when pushed to these conditions. He detected the melt in experiments conducted at the Advanced Photon Source of Argonne National Laboratory and at the National Synchrotron Light Source of Brookhaven National Laboratory.
Jacobsen uses small gem diamonds as hard anvils to compress minerals to deep-Earth conditions. "Because the diamond windows are transparent, we can look into the high-pressure device and watch reactions occurring at conditions of the deep mantle," he said. "We used intense beams of X-rays, electrons and infrared light to study the chemical reactions taking place in the diamond cell."
Jacobsen's findings produced the same evidence of partial melt, or magma, that Schmandt detected beneath North America using seismic waves. Because the deep mantle is beyond the direct observation of scientists, they use seismic waves — sound waves at different speeds — to image the interior of the Earth.
"Seismic data from the USArray are giving us a clearer picture than ever before of the Earth's internal structure beneath North America," Schmandt said. "The melting we see appears to be driven by subduction — the downwelling of mantle material from the surface."
The melting the researchers have detected is called dehydration melting. Rocks in the transition zone can hold a lot of H2O, but rocks in the top of the lower mantle can hold almost none. The water contained within ringwoodite in the transition zone is forced out when it goes deeper (into the lower mantle) and forms a higher-pressure mineral called silicate perovskite, which cannot absorb the water. This causes the rock at the boundary between the transition zone and lower mantle to partially melt.
"When a rock with a lot of H2O moves from the transition zone to the lower mantle it needs to get rid of the H2O somehow, so it melts a little bit," Schmandt said. "This is called dehydration melting."
"Once the water is released, much of it may become trapped there in the transition zone," Jacobsen added.
Just a little bit of melt, about one percent, is detectible [sic] with the new array of seismometers aimed at this region of the mantle because the melt slows the speed of seismic waves, Schmandt said.
The USArray is part of EarthScope, a program of the National Science Foundation that deploys thousands of seismic, GPS and other geophysical instruments to study the structure and evolution of the North American continent and the processes the cause earthquakes and volcanic eruptions.
The National Science Foundation (grants EAR-0748797 and EAR-1215720) and the David and Lucile Packard Foundation supported the research.
The paper [pay-walled] is titled "Dehydration melting at the top of the lower mantle." In addition to Jacobsen and Schmandt, other authors of the paper are Thorsten W. Becker, University of California, Los Angeles; Zhenxian Liu, Carnegie Institution of Washington; and Kenneth G. Dueker, the University of Wyoming.

Why did NASA's chief just shake up the agency's plans to land on the Moon?:
NASA acting Administrator Sean Duffy made two television appearances on Monday morning in which he shook up the space agency's plans to return humans to the Moon.
Speaking on Fox News, where the secretary of transportation frequently appears in his acting role as NASA chief, Duffy said SpaceX has fallen behind in its efforts to develop the Starship vehicle as a lunar lander. Duffy also indirectly acknowledged that NASA's projected target of a 2027 crewed lunar landing is no longer achievable. Accordingly, he said he intended to expand the competition to develop a lander capable of carrying humans down to the Moon from lunar orbit and back.
"They're behind schedule, and so the President wants to make sure we beat the Chinese," Duffy said of SpaceX. "He wants to get there in his term. So I'm in the process of opening that contract up. I think we'll see companies like Blue [Origin] get involved, and maybe others. We're going to have a space race in regard to American companies competing to see who can actually lead us back to the Moon first."
There are a couple of significant takeaways from this interview. First is the public acknowledgement by a senior NASA official that the space agency's current timeline of a 2027 landing is completely untenable. And secondly, the timing of Duffy's public appearances on Monday morning seems tailored to influence a fierce, behind-the-scenes battle to hold onto the NASA leadership position.
SpaceX won a contract from NASA, worth $2.9 billion, in April 2021 to develop and modify its ambitious Starship rocket to serve as a "human landing system" (HLS). This rocket would work in concert with NASA's Space Launch System and Orion spacecraft to get humans from Earth, to the lunar surface, and back. Two years later Blue Origin, a rocket company founded by Jeff Bezos, won a second contract, worth $3.4 billion, to develop a second lander.
Duffy is correct that SpaceX is moving slower than anticipated. The company must still cross several technical hurdles before it can provide landing services to NASA. In their funded contracts for reusable landers, SpaceX and Blue Origin must refuel their vehicles in low-Earth orbit, something that has never been done before on a large scale.
When Duffy says "companies like Blue" may get involved, he is not referring to the existing contract, in which Blue Origin will not deliver a ready-to-go lunar lander until the 2030s. Rather he is almost certainly referring to a plan developed by Blue Origin that uses multiple Mk 1 landers, a smaller vehicle originally designed for cargo only. Ars reported on this new lunar architecture three weeks ago, which company engineers have been quietly developing. This plan would not require in-space refueling, and the Mk 1 vehicle is nearing its debut flight early next year.
Duffy also cites "maybe others" getting involved. This refers to a third option. In recent weeks, officials from traditional space companies have been telling Duffy and the chief of staff at the Department of Transportation, Pete Meachum, that they can build an Apollo Lunar Module-like lander within 30 months. Amit Kshatriya, NASA's associate administrator, favors this government-led approach, sources said.
On Monday, in a statement to Ars, a Lockheed Martin official confirmed that the company was ready if NASA called upon them.
"Throughout this year, Lockheed Martin has been performing significant technical and programmatic analysis for human lunar landers that would provide options to NASA for a safe solution to return humans to the Moon as quickly as possible," said Bob Behnken, vice president of Exploration and Technology Strategy at Lockheed Martin Space. "We have been working with a cross-industry team of companies and together we are looking forward to addressing Secretary Duffy's request to meet our country's lunar objectives."
NASA would not easily be able to rip up its existing HLS contracts with SpaceX and Blue Origin, as, especially with the former, much of the funding has already been awarded for milestone payments. Rather, Duffy would likely have to find new funding from Congress. And it would not be cheap. This NASA analysis from 2017 estimates that a cost-plus, sole-source lunar lander would cost $20 billion to $30 billion, or nearly 10 times what NASA awarded to SpaceX in 2021.
SpaceX founder Elon Musk, responding to Duffy's comments, seemed to relish the challenge posed by industry competitors.
"SpaceX is moving like lightning compared to the rest of the space industry," Musk said on the social media site he owns, X. "Moreover, Starship will end up doing the whole Moon mission. Mark my words."
Duffy's remarks on television on Monday morning, although significant for the broader space community, also seemed intended for an audience of one—President Trump.
The president appointed Duffy, already leading the Department of Transportation, to lead NASA on an interim basis in July. This came six weeks after the president rescinded his nomination of billionaire and private astronaut Jared Isaacman, for political reasons, to lead the space agency.
Trump was under the impression that Duffy would use this time to shore up NASA's leadership while also looking for a permanent chief of the space agency. However, Duffy appears to have not paid more than lip service to finding a successor.
Since late summer there has been a groundswell of support for Isaacman in the White House, and among some members of Congress. The billionaire has met with Trump several times, both at the White House and Mar-a-Lago, and sources report that the two have a good rapport. There has been some momentum toward the president re-nominating Isaacman, with Trump potentially making a decision soon. Duffy's TV appearances on Monday morning appear to be part of an effort to forestall this momentum by showing Trump he is actively working toward a lunar landing during his second term, which ends in January 2029.
Duffy has appeared to enjoy the limelight that comes with leading NASA. In the future, one source said, "Duffy wants to be president." The NASA position has afforded him greater visibility, including television appearances, to expand his profile in a positive way. "He doesn't want to give up the job," the source added.
A Republican advisor to the White House told Ars that it is good that Duffy has moved beyond his rhetoric about NASA beating China to the Moon and to look for creative tactics to land there. But, this person said, the mandate from the Trump administration is to dominate the emerging commercial space industry, not hand out large cost-plus contracts.
"Duffy hasn't implemented any of the strategic reforms of Artemis that the president proposed this spring," the Republican source said. "He has the perfect opportunity during the current shutdown, but there is no sign of any real reform under his leadership. Instead, Duffy is being co-opted by the deep state at NASA."
