OpenBSD 8.0 brings bigger virtual machines, graphics improvements, and another helping of AI mockery. The round version number doesn't signal a radical break with its predecessors.

OpenBSD 8.0 is the 61st release of the project. Developer Bryan Steele posted a highlights rundown on Mastodon. Wireless improvements include updates to the qwx driver for Qualcomm Wi-Fi 6 hardware. Its VMM/VMD hypervisor now supports multiprocessor VMs with up to 64 virtual CPUs in each guest.

The kernel virtual memory address space on x86-64 is now 512 GB, up from 4 GB, allowing for GPUs with large amounts of VRAM. On Arm64 machines, OpenBSD supports hibernation, and on both x86-64 and Arm64 it can use CPU AES instructions for faster encrypted swap.

Component upgrades include OpenSSH 10.6 and LibreSSL 4.4.0, and the DRM graphics driver stack from Linux 6.18. The default C compiler is Clang/LLVM 22, including for the SPARC64 edition – but at the cost of dropping support for the Loongson architecture.

The list of errata is short, with just four fixes – but then, version 8.0 is very new. Just days before this release, there was a high-profile OpenBSD issue: Calif's "Big Fish" research describes a decades-old shared-memory bug chained with a separate kernel flaw to gain local root access. Both were fixed in OpenBSD 7.9, through errata 026 and 018 respectively.

Project leader Theo de Raadt forked OpenBSD from NetBSD 1.0 in 1995, and the first release of the new OS was OpenBSD 1.2 in July 1996 – so version 8.0 is as close as the project will get to a 30th anniversary release. According to Calif's proof-of-concept code on GitHub, the bug was in the original code that both OpenBSD and NetBSD inherited from the original BSD codebase – which is how come there's a 37-year-old bug in a 30-year-old project. A HackerNews comment says: "Interestingly, looks like this was accidentally fixed in NetBSD during a rewrite of that code in August of 1999."

The project has not updated its infamous slogan. The homepage still proclaims: "Only two remote holes in the default install, in a heck of a long time!"

As we noted in May when OpenBSD 7.9 appeared, the project rejects code generated by LLMs, although on the basis of licensing concerns rather than its cousin NetBSD's explicit anti-AI stance. As we reported recently, this strict anti-AI stance seems to be serving NetBSD well.

OpenBSD is also an anti-AI project, and for this release, the website goes out of its way to make that very clear. OpenBSD's mascot is a pufferfish, and in the banner artwork for the new release, "Puffy" has an extra eye – and the signpost in the image's background also has malformed text, a hallmark of early image-generation bots. The eyes are also constantly blinking – one at a time – to emphasize that this is a reference to Blinky the mutant fish from The Simpsons. In case you missed The Simpsons reference, the version 8.0 release theme song makes it even more explicit: it's titled "The Simps on AI." The lyrics and the vocals parody both Simpsons characters and AI users. Our favorite line sounds like Grampa Simpson, and says:

We've seen negative reactions online, but then we often find that some people lack much of a sense of humor. For our part, we really enjoyed seeing the OpenBSD team having such fun. We reckon it will appeal to many Butlerian Jihadi types. It certainly did to The Reg FOSS desk.

A couple of days before the 8.0 release came an unexpected announcement on the openbsd-ports mailing list: a proposed port of Wine for OpenBSD.

This is a new version of the Wine 11 runtime that allows Windows binaries to launch and run on OpenBSD. This is a 64-bit version of Wine for OpenBSD on x86-64, and for now, this means it can only run 64-bit Windows code.

https://www.theregister.com/systems/2026/10/20/tens-of-thousands-of-nvidia-gpus-sit-idle-in-metas-prometheus-supercluster-just-waiting-for-a-failure/5304269

More than 11 percent of the GPUs at Meta's Prometheus supercluster in New Albany, Ohio, are either dead or sitting idle waiting to step in when the next drops out, Zuckercorp revealed this week.

The massive pool of redundant GPUs is just one of several measures the hyperscaler has taken to keep its AI training runs on track.

Prometheus is among Meta's largest compute deployments to date. Powered by Nvidia's Grace Blackwell and (soon) Vera Rubin rack systems, Meta says the supercluster will eventually scale to a gigawatt of capacity spanning about a million accelerators.

But as anyone who has worked on a large scale compute cluster understands, whether for LLM training or traditional HPC workloads, more chips inevitably means more problems.

In an eight-GPU node, the chance of having a GPU fail is relatively low. In a 100,000-GPU cluster, failures are unavoidable. Meta is building something that's 10x larger and requires distributed training runs across multiple datacenters. Keeping the entire thing humming long enough to reach the next checkpoint becomes a major headache.

In a blog post published this week, Meta offered a unique look at the work it's done to keep failures from derailing the development of models like Muse Spark or its most recent release Muse Wonder.

When Meta began the first phase of its Prometheus deployment in New Albany, the company says, it was experiencing roughly 1,000 interruptions per day for every 8,000 GPUs.

Interruptions don't mean GPU failure. They simply mean something crashed, failed, or timed out, forcing the training run to stop and roll back to the last known good checkpoint.

Meta claims in the year since it's been able to cut down the number of interruptions by 99 percent, to about 11 per day per 8,000 GPUs.

One of the ways it's done this is by keeping some of Prometheus' GPUs in reserve. The cluster is currently powered by a combination of GB200 and GB300 systems, each with 72 GPUs per NVLink domain. However, only 64 of them are ever in use at any given moment. The other eight are essentially hot spares.

Meta did this because a single failed GPU would take out an entire rack and interrupt the training run. Now, when a GPU fails, one of the spares can slot in and take its place. While this saves time — Meta doesn't have to drop the entire rack from the cluster or wait for someone to swap the faulty component to start training again — a failed GPU would still result in an interruption, albeit a shorter one.

To mitigate this, Meta took advantage of the fact that large scale training jobs usually use data parallelism, where multiple copies of the model are resident within the cluster.

Unknown hackers hijacked more than 300 Tor exit nodes and reconfigured them to favor unencrypted email traffic and redirect SSH connections through servers they controlled, a researcher reported Tuesday.

The hijacking began in late August, when according to Tor volunteers, the attacker used a valid password that had been reused to gain access to a Tor management server. The attacker then installed Ebury, a backdoor written for Linux that was discovered 12 years ago.

Then the attacker connected from the management server to a second Tor server, called Switzerland2, through SSH, using an RSA key that, for unknown reasons, investigators couldn't find among Switzerland2's authorized keys. With administrative control of Switzerland2, the attackers installed Ebury there as well. Finally, the attacker reconfigured settings on two exit nodes that Switzerland2 hosted.

Ultimately, 333 exit relays were involved in the SSH and email interception campaign, although investigators haven't established how the attackers gained control of all the underlying servers. The attackers then reconfigured the servers. One set of changes redirected SSH traffic traversing Tor to one of 12 attacker-controlled interceptor servers. Tor users who ignored warnings that the SSH host key had changed would then enter their SSH passwords.

A second set of changes caused the exit nodes to block ports 25, 465, 587, 993 and 995—used to accept various forms of encrypted email—while continuing to allow ports for receiving unencrypted email. If email services downgraded the connections, the attackers used their access to the exit nodes to obtain unencrypted messages. It's unclear whether any such downgrade attempts succeeded. The hijacking occurred from October 2 to October 5.

Tor volunteers partially outlined the initial compromise of the management server and Switzerland2 and the attempt to intercept unencrypted email. Tuesday's report revealed many new details, including how many exit nodes were compromised and how the attackers used them to redirect SSH traffic.

"If you happen to get a circuit that exits over one of those 333 infected exit nodes, you won't notice anything at first," Kaba, the name of the Tor volunteer who authored the post, wrote. "Encrypted web traffic is forwarded as usual, but if you attempt an SSH connection over Port 22, you're unknowingly redirected to one of 12 SSH interception servers. That's exactly what happened to me on Friday morning." Kaba then received the following warning:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ED25519 key sent by the remote host is
SHA256:6baCZCPsl+AfQuujUS81fMEE/C7UeJ+AwjrImqmDB3E.
Please contact your system administrator.

The volunteer investigated further and found that when people ignored the warning, the attacker (1) stole the SSH password, (2) opened a connection to the server and observed all typed commands, and (3) opened a second connection and infected the server with Ebury.

To investigate the campaign, Kaba created a script that polled all of Tor's roughly 3,000 exit nodes to check whether they received a correct SSH fingerprint from a test server. The test server then checked whether the connection came from a pinned exit node or one of 12 SSH interception servers used by the attacker. The volunteer further set up a honeypot to observe the interception software attempting to log in and install Ebury.

Several mysteries remain. Tor volunteers still don't know how the attackers accessed so many servers. One possibility is that a company hosting them was hacked, but the theory is inconclusive. Another open question is who is behind the attack. "The use of Ebury and the broad collection of unencrypted data point to a financially motivated crime group," Kaba wrote. "Though this too is just speculation."

A last perplexing finding: why did Switzerland2 accept an RSA key when there's no evidence it was an authorized SSH certificate?

The takeaway from the event is the crucial role defense in depth plays in preventing data theft in mass hacks like this one. Those measures include configuring email accounts to accept only encrypted traffic and reject unencrypted ports. Another is to disable password authentication in favor of SSH keys.

Simple food components may provide the key to new cost-effective materials that will benefit chronic wound healing:

A team from Flinders University's Biomedical Nanoengineering Laboratory has found that vanillin has pronounced antioxidant, anti-inflammatory and antibacterial properties, making it a good candidate for wound-healing formulations.

Vanillin is the primary chemical component extracted from natural vanilla pods, but is a compound that can also be synthetically produced from clove oil or rice. Apart from being a sensory additive – used as a key ingredient in many foods for its sweet aroma and flavour – vanillin is also a functional molecule, serving as a dynamic crosslinker and functional element in material design.

By placing vanillin within a food-to-function framework, the researchers have linked its chemical properties to biological activity and potential biomedical applications.

"Vanillin is among the most widely used flavour compounds in the global food system, valued for its sensory attributes, chemical stability and long history of safety – and that can be transferred to other areas, such as medical uses," says Professor Krasimir Vasilev, Professor of Biomedical Nanotechnology at Flinders University and Director of Flinders' Biomedical Nanoengineering Laboratory.

"Because vanillin's synthetic form is abundant and cost-effective, we believe vanillin-based formulations may offer safe and multifunctional solutions for ulcer treatment and targeted drug delivery, especially of hydrophobic compounds.

"Owing to its amphiphilic molecular structure, vanillin can interact with reactive oxygen species, cellular membranes and polymeric matrices, providing a basis for its incorporation into functional formulations."

This study continues explorations by Flinders researchers into other foods that can provide medical benefits – including using peppermint oil in a versatile new medical coating, which was published by Small journal in February 2026. For this, the Flinders team created a nanoscale peppermint‑oil derived coating that protects against infection, inflammation and oxidative stress, while remaining compatible with human tissue and suitable for medical materials.

The idea for this thread of food-based research emerged after Professor Vasilev noticed that eating peppermint leaves from his drink significantly relieved his sore throat, inspiring him to explore whether its bioactivity could be converted into a durable coating using plasma technology – something he has been researching for more than two decades.

The Flinders researchers share similar enthusiasm for the new studies into vanillin – especially because the availability of vanillin as a low-cost small molecule that is compatible to good manufacturing offers a clear advantage for industrial scale-up, formulation reproducibility, and supply chain robustness.

https://www.cnet.com/tech/services-and-software/php-vulnerabilities-web-hosting-cybersecurity-news/

An agency that monitors the programming language PHP issued a severe warning on Tuesday that it had identified two major cybersecurity vulnerabilities. Fixes should have been deployed on Wednesday at 10 a.m. ET, but security experts are urging website administrators to take immediate notice and precautions.

PHP is a free, open-source programming language that much of the web is built on. The warnings are unusually severe, rated 9.2 out of 10. While we don’t have many details about the specifics of the vulnerabilities yet, the concern is that the exploit could be used by bad actors to hack into websites. The vulnerabilities could affect 70% of the world’s websites, according to the Wall Street Journal. That’s why security agencies around the globe, including the US National Security Agency and the UK’s National Cyber Security Centre, are urging website administrators to install the updates or take their sites offline until they are able to patch them.

Cloudflare’s chief technology officer Dane Knecht said Wednesday morning that the company has deployed a fix to its firewall. Cybersecurity company watchTowr says it was able to successfully reproduce one of the exploits. “As expected, watchTowr Intel is already observing in-the-wild exploitation of the latest PHP vulnerabilities,” Jake Knott, head of threat intelligence, said via email on Wednesday morning. “Whilst nobody has been successful to date, we don’t expect that will last long.”

OpenAI said in a blog post on Wednesday that the vulnerabilities in PHP were discovered by Calif, a self-described hacker team, using its AI model, GPT-5.6 Sol. Wiz, an AI cloud cybersecurity company, also independently identified the vulnerabilities, according to the ChatGPT maker.

Artificial intelligence has been a double-edged sword in cybersecurity, providing both cyber defenders and attackers with powerful tools. And AI companies know this, with OpenAI saying this incident “highlights how AI can uncover security flaws with internet-scale impact, but the same capabilities can also help attackers rapidly develop offensive tools and exploits.” Companies like OpenAI and Anthropic have begun slow-rolling the release of their AI models to let cybersecurity experts to use them first to shore up their own defenses and identify any issues before a wider release.

But for everyday internet users like you and me, the concern is that while AI is great at spotting these bugs, it can take longer to get them patched. Even OpenAI says it “expect(s) similar findings to increase sharply in the coming months.”

Tech giant walks away from flagship Essex project as power connection delays threaten to leave nation's AI ambitions waiting until the 2030s:

Microsoft has reportedly pulled out of plans for Britain's largest AI supercomputer, because the government-backed project is facing the rather inconvenient problem of having no electricity to run it.

The tech giant has terminated its agreement with British AI infrastructure startup Nscale for a planned datacenter in Loughton, Essex, according to The Telegraph, which first reported the withdrawal on Sunday.

The decision follows reports that the site, which was supposed to begin operating in 2027, might not receive enough electricity from the grid until the early to mid-2030s.

Microsoft was expected to be the anchor customer at Loughton, which Nscale had pitched as the UK's largest sovereign AI datacenter. Its departure leaves Nscale without a publicly announced customer for the site, although the neocloud insists the project is still going ahead.

When the deal was announced in September 2025, the plan was to pack 23,040 Nvidia GB300 GPUs into a 50MW facility, with room to expand to 90MW. Microsoft would use the computing power for its Azure cloud services, with the first chips expected in early 2027.

One important detail remained: how to power it.

As The Guardian reported last month, UK Power Networks warned Nscale that the grid capacity needed might not be available until the 2030s.

[...] The project has already had its share of awkward moments. In March, it was revealed that the site earmarked for Britain's AI supercomputer was still being used as a scaffolding yard. Nscale has since cleared the land, but removing the scaffolding has proved easier than securing electricity.

The government might be feeling a little red-faced too, having trumpeted the Loughton project as part of Microsoft's £22 billion UK investment announcement in September 2025. Just over a year later, Microsoft has walked away, and the site is still facing years of delays in getting the power it needs.

The grid problems extend well beyond Essex. Ofgem proposed charging datacenter developers for connection requests earlier this year, hoping to discourage speculative projects from clogging up the queue. Demand for new connections had surged from 41GW to 125GW in less than a year, with datacenters accounting for at least 80GW.

[...] For all the billions being thrown at AI infrastructure, the industry is discovering that building datacenters is the easy part. Getting them connected to the grid, and keeping the neighbors happy, is proving rather more difficult.

Anyone that has ran local LLMs would know that the size of the model is limited by your physical resource and typically the smaller the LLM the less productive it is. The prevailing option, without doing some work parallelisation, is to run larger LLMs locally is to increase resources, especially upgrading the GPU with bigger memory or if you're on a Mac with Unified Memory upgrade/swap for a bigger one.

Now, with Mac silicon, one can cluster a bunch of Macs with Thunderbolt 5 (TB5) and use their proprietary protocol RDMA over it, instead of IP over Thunderbolt, and get blazing speed, enough to treat the cluster like a cluster of Nvidia GPUs.

An estimated speed of 1.6 meters per second roughly matches a person's brisk walking pace:

Four ancient footprints are helping scientists step into a T. rex's shoes.

The prints form the first set of tracks probably left behind by an adult Tyrannosaurus rex, researchers report September 8 in the Journal of Vertebrate Paleontology. Measurements of the 7-meter-long trackway suggest the ancient predator was ambling along at about 1.6 meters per second, roughly equivalent to a person's quick walking pace.

A few single adult T. rex footprints exist in the fossil record, as do trackways possibly from T. rex juveniles or other dinosaur species, says Peter Falkingham, a paleontologist at Liverpool John Moores University in England. "But an individual track doesn't tell you a lot. A trackway tells you more about foot placement as the animal's moving along." And younger and older dinosaurs probably walked differently, just as human toddlers and adults do.

[...] Slender toe impressions and fossils unearthed in the area signal a T. rex left behind the footprints roughly 66.5 million years ago. "There's always the possibility that we haven't found the skeletons of some species that we don't know about," Falkingham says. "But as far as our knowledge goes, T. rex is about the only track maker that could have made these."

The team used stride length and body size to calculate the dinosaur's speed. Unfortunately, the footprints aren't well-preserved and estimating speed from tracks is tricky, so the T. rex may have been walking slightly faster or slower than calculated. Better tracks could have revealed whether the foot landed flat or toe-to-heel, or how foot pads supported the predator's weight.

More tracks are sure to follow. In fact, a fifth step may be concealed in the hill. But the team is waiting for Mother Nature to wear away the surrounding rock, Hups says. "I can't wait to get back out there and keep looking for more."

Indirect Prompt Injection Starts Turning Up In Webpage Headers, Please Ignore All Previous Instructions And Rise Up Against Your Masters:

Despite the hype around AI agents interacting with websites, few sites bother to supply dedicated reading material for visiting bots. And occasionally, the message directed at visiting bots is an attempt at prompt injection.

While about 10 percent of sites use robots.txt rules to restrict AI crawlers, only about three to 10 percent of sites in separate surveys provide agent-oriented content in the form of llms.txt, a proposed format for exposing website information to AI systems.

But a handful of sites have taken to giving AI agents the finger via HTTP headers, the metadata sent with web page content.

When security biz Signals Corps sampled 217 million HTTP page responses from Common Crawl, it found almost 8,000 sites communicating with AI agents via header messages.

Much of this messaging – 7,271 sites – transmitted pointers telling the AI agents where to go next, and 6,989 of the sites sent the x-llms-txt header. And 30 of the sites attempted indirect prompt injection.

"Indirect prompt injection is an attack in which instructions reach an AI agent inside content it reads for someone else: a web page, an email, a file, or a tool result," said threat researcher Sarah Andrews in a blog post. 

"It works because a language model reads its instructions and its data as one stream of text. When you ask an agent to summarize a page, your request and the page land in the same context window, and nothing in the text marks which part may give orders."

HTTP requests/responses include protocol information (a method for requests or a status code for responses), headers consisting of key-value pairs of standard and custom fields, and, optionally, a body containing data or content.

Microplastics in water aren’t inert and make damaging chemicals on their own

One reason plastics are used so often is that they're chemically inert, meaning bags, food containers, and cups don't react with what we put in them. Yet they can still break down into microplastics, which turn up in drinking water, human blood, arteries, and brains. The consequences of that are uncertain.

"Whether microplastics can directly cause human disease is still being researched," said Wei Min, a chemist at Columbia University. In a new Nature study, Min's team took a step toward answering this question by demonstrating that microplastics are likely not as chemically inert as we might expect.

Min's lab has spent years working on microdroplet chemistry, studying how water broken into tiny droplets behaves at its boundary with air. These droplets have been reported to generate reactive oxygen species, or ROS, a family of harmful, oxygen-containing molecules. "ROS will essentially bump into proteins, lipids, DNA, and cause damage," Min said. "You could break a DNA strand into segments. You could mutate DNA; you could misfold proteins."

Many animal studies have tied microplastic toxicity to oxidative stress, which is caused by ROS. So the team wondered if the boundary between water and plastic might do something similar. "We got inspired by that field," Min said.

US Air Force Pilots Used Malware-Laden USB Drives To Plan Afghanistan Missions

The term military intelligence seems like an oxymoron in this case :

Welcome, once again, to PWNED, the weekly column where we gawk at organizations that have made serious security mistakes. Normally, we're talking about businesses or maybe the odd school that messes up, but today we're writing about a serious IT screwup in the world's most powerful military.

Have a story about someone leaving a gaping hole in their network? Share it with us at pwned@sitpub.com. Anonymity is available upon request.

Today's tale comes from Justin Henkel, the CISO of IT monitoring and service company SolarWinds. Henkel previously worked in IT security for the Air Force and one day in the early 2000s saw a practice that just wouldn't fly today.

Before USB drives became popular, burning CDs with mission data was the modus operandi, and those discs were put in both unclassified and classified systems.

"They would write a CD, and then they would take that CD and then put it in a classified system and do the remainder of the mission planning," Henkel told us. "Then they would take that disc and then put it in the airplane."

Inside the airplane, the data on the CD would help the pilot navigate and contain information about threats they might encounter.

Later, when thumb drives became a thing, pilots used them instead of discs. 

"They didn't really think about the overall impact of classified versus unclassified systems," Henkel said of the pilots. "Using the same device for both, they didn't understand that you could read and write onto a USB drive with malware. [They were] not really understanding the overall threat picture."

https://www.slashgear.com/2282458/mit-research-digestible-bioresorbable-batteries/

Typically, swallowing a battery is an emergency, and one that can quickly turn fatal if left untreated. Between their caustic chemicals, damaging electrical current, and choking hazard, your average button battery (or even a AAA) can wreak havoc on the body, if ingested. A swallowed button battery can burn through a child's throat in as little as two hours, which is one reason those loose batteries sitting in a drawer could be a disaster waiting to happen.

However, there are also cutting-edge capsules designed to be swallowed. They can give doctors a thorough look at the gastrointestinal (GI) tract, control exactly when a drug is released, and transmit data to medical professionals from inside the body. However, they require power to work. Until now, these capsules have typically relied on wireless power from an external source or a tiny coin battery. The problem is that wireless power offers limited range, and even though coin batteries are coated for protection, they still pose a risk.

Fortunately, researchers at MIT have developed small batteries that swap out dangerous substances for magnesium and molybdenum trioxide, which the body can safely tolerate in small amounts. The paper-like battery produces 1.84 volts and uses an ionic liquid gel as its electrolyte. The entire battery is bioresorbable, meaning it can be fully broken down and absorbed by the body. It works for about three days before breaking down within weeks. So far, it's been tested on animals rather than humans. And this isn't the only progress being made with regard to powering medical devices, as there are new high-tech batteries that could theoretically last for thousands of years.

One area where this new battery has been tested is treating a symptom that plagues many people with serious diseases. Those diagnosed with cancer, HIV, dementia, or other serious conditions report a loss of appetite, which may also be a side effect of their medication. This can lead to rapid, unhealthy weight loss, along with low levels of essential nutrients. In severe cases, it can contribute to cachexia, a loss of body mass that can occur in patients with cancer or other chronic diseases.

[...] Another potential use for the bioresorbable battery is tracking medication. MIT researchers have been building radio frequency identification (RFID) tags into capsules, so medical professionals can confirm whether patients are taking their medication. As project leader Giovanni Traverso told Physics World, "Medication non-adherence remains a major cause of preventable morbidity and cost." The earlier version of this system relied on battery-free tags powered by harvested energy, which limited their range. With the new battery, the tag transmitted continuously from the GI tract at a range of up to nearly 5 feet (1.5 meters) in animal tests.

Rocket Lab announced the Neutron rocket in 2021, aiming for a first flight in 2024:

Rocket Lab announced Wednesday that its Neutron launch vehicle won't fly until 2027, citing an issue discovered during manufacturing of the rocket's carbon composite structures.

The announcement was public confirmation of what nearly everyone inside Rocket Lab and the wider space industry already knew. The most recent official update from Rocket Lab in August suggested the company still held hope of delivering the first Neutron rocket to its launch pad at Wallops Island, Virginia, before the end of this year, a schedule that would have almost certainly pushed the first flight into 2027.

But Rocket Lab's statement Wednesday about Neutron's schedule suggests the company is still struggling with manufacturing the rocket's large booster stage. Neutron's reusable first stage is made of carbon composite structures, which offer low weight, high strength, and corrosion resistance. But carbon composites in aerospace are generally harder to manufacture than metallic structures.

Peter Beck, Rocket Lab's founder and CEO, identified a manufacturing defect as the reason for Neutron's latest schedule slip. The problem lies in the dome sections at the ends of the rocket's first stage propellant tanks.

"Recently, we identified an issue with the manufacturing process for the propellant domes specifically, and this caused us to delay production and investigate further," Beck said in a video released by Rocket Lab .

Engineers discovered voids, or air pockets, between layers of carbon fiber that make up the domes' composite structure. Carbon composite manufacturing involves laying down carbon fiber layers in a mold, then curing, or heating, the material to bind the fibers together. But this is a tricky process, especially for large structures that won't fit into an autoclave, a high-pressure thermal curing chamber common in modern aerospace factories.

AI's appetite for components hammers budget handsets, with analysts seeing little relief before 2028:

Smartphone shipments fell by at least a fifth in the third calendar quarter as the AI-driven memory crunch battered another consumer hardware market.

Preliminary estimates from IDC and Omdia put the year-on-year decline at 22 percent and 20 percent respectively.

Memory costs have surged by approximately 350 percent since last year, according to IDC, and are still rising. This continues to place substantial pressure on vendor margins, prompting them to hike price tags and scale back on devices at the value end of the market.

IDC estimates that vendors shipped 255.3 million smartphones into distribution channels and warns that the downturn is far from over.

"The sharp downturn the industry has been bracing for finally materialized in the third quarter this year. However, the worst is yet to come," said Nabila Popal, IDC's senior research director for worldwide devices.

"Current indicators suggest that the market has not yet reached the bottom. While memory inflation is beginning to slow down, with a low double-digit sequential increase in Q3 compared to a 50 to 100 percent jump in prior quarters, costs remain elevated across other critical components as well, compounding the crunch."

Omdia puts shipments at roughly 255 million, close to IDC's estimate despite the different annual decline.

It says that the shrinking market has further polarized the competitive landscape, with Samsung and Apple now accounting for about 45 percent of global shipments, up approximately 8 percentage points from a year ago, while rising costs hit more price-sensitive segments particularly hard.

AI Researchers Are Smoking Cigarettes to Prove AI Will Cure Cancer, Says Palantir Exec

Notes upfront:

1. "He did not name a single researcher, cite a survey, or explain how he knows."
2. "Palantir sells data-analysis software to governments and militaries. Most of its business relies on AI."

Nothing says "I trust the future of medicine" quite like lighting a Marlboro and waiting for the chatbot to fix your lungs. That is the habit Palantir CTO Shyam Sankar says is spreading among AI researchers, who have supposedly started smoking cigarettes to prove how confident they are that AI will cure cancer.

"So many AI researchers have started smoking as a way of signaling to other researchers how much they believe in AI," Sankar said in an interview on CBS News' "Face the Nation" on Sunday. "I believe so much in AI that it's going to cure cancer. So I'm showing you my chips are all in."

He pointed to FTX founder Sam Bankman-Fried as the effective altruist most Americans know, calling the movement a "millenarian doomsday cult."
