The Pentagon is spending $13.4 billion on AI this year alone:
The designation enters Maven into the Future Years Defense Program as a protected line item, giving it visibility and stability across budget cycles that experimental programs lack. The U.S. Army will manage all Maven contracts going forward, and oversight will transfer from the National Geospatial-Intelligence Agency to the Chief Digital and AI Officer within 30 days, with program-of-record status expected before the close of fiscal year 2026 on September 30.
Palantir took over and built a full command-and-control platform that ingests data from more than 150 sources, according to Palantir's public demonstrations: satellite imagery, drone video, radar, infrared sensors, signals intelligence, and geolocation data. Computer vision algorithms trained on millions of labeled images automatically detect and classify battlefield objects, with yellow-outlined boxes marking potential targets, blue outlines flagging friendly forces and no-strike zones, and an ‘AI Asset Tasking Recommender’ proposing which weapons platforms and munitions should be assigned to each target.
NGA Director Vice Admiral Frank Whitworth stated at Palantir's AIPCON 9 conference in March that Maven can generate 1,000 targeting recommendations per hour, as reported by The Register, with the 18th Airborne Corps reportedly achieving comparable targeting output to the 2,000-person cell used during Operation Iraqi Freedom with roughly 20 people. Maven now has more than 20,000 active users, a figure that has quadrupled since March 2024. The platform was used during the 2021 Kabul airlift, to supply target coordinates to Ukrainian forces in 2022, and most recently during Operation Epic Fury against Iran in 2026, where it reportedly enabled processing of 1,000 targets within the first 24 hours, according to SpaceNews. NATO acquired a version in March 2025.
Meanwhile, the FY2026 defense budget reached $1.01 trillion, representing a 13% increase over FY2025, and for the first time included a dedicated AI and autonomy budget line of $13.4 billion, according to MeriTalk's analysis of the Pentagon budget request. That allocation covers unmanned aerial vehicles ($9.4 billion), maritime autonomous systems ($1.7 billion), and supporting AI software ($1.2 billion). The Pentagon now oversees more than 685 AI-related projects tied to weapons systems, per Congressional Research Service tracking.
[...] The Brennan Center for Justice, in a March 2026 report titled "The Business of Military AI," documented that Hegseth halved staffing at the Office of the Director of Operational Test and Evaluation and shuttered the Civilian Protection Center of Excellence. The center's researchers wrote that "the accelerating use of AI in warfighting has not been met with commensurate urgency to reckon with its dangers."
CSIS research has quantified AI-assisted targeting error propagation at 25% under variable conditions, according to a January 2026 analysis. Whitworth stated that by June 2026, Maven will begin transmitting "100 percent machine-generated" intelligence to combatant commanders. “No human hands actually participate in that particular template and that particular dissemination,” he added. “We want to use it for everything, not just targeting.”
Senator Elissa Slotkin introduced the AI Guardrails Act this month, which would prohibit the DoD from using autonomous weapons to kill without human authorization and bar AI use for domestic mass surveillance, The Hill reported. The FY2026 NDAA already declares targeting and launch authorization "inherently governmental" functions and requires reporting of autonomous weapons directive waivers to Congress.
[...] Meanwhile, a recent CSIS analysis documented Russian forces striking approximately 300 targets per day using unmanned systems in Ukraine, with data collection feeding AI platforms designated Platform-GNS and Avtomat. Russia voted against the December 2024 UN General Assembly draft resolution on lethal autonomous weapons alongside only North Korea and Belarus. That resolution passed 166-3 but remains non-binding; no international treaty currently governs lethal autonomous weapons systems. With AI reshaping the techonolgy industry, its influence has now begun to slip into the long shadow of military usage, and the implications of such deals remains to be seen.
The date makes it suspicious, but both the accidental publishing of source and the tear down sounds all too plausible.

- Claude code source "leaks" in a mapfile
- people immediately use the code laundering machines to code launder the code laundering frontend
- now many dubious open source-ish knockoffs in python and rust being derived directly from the source
What's anthropic going to do, sue them? Insist in court that LLM recreating copyrighted code is a violation of copyright???
Source code with a side of Vidar stealer and GhostSocks
Tens of thousands of people eagerly downloaded the leaked Claude Code source code this week, and some of those downloads came with a side of credential-stealing malware.
A malicious GitHub repository published by idbzoomh uses the Claude Code exposure as a lure to trick people into downloading malware, including Vidar, an infostealer that snarfs account credentials, credit card data, and browser history; and GhostSocks, which is used to proxy network traffic.
Zscaler's ThreatLabz researchers came across the repo while monitoring GitHub for threats, and said it's disguised as a leaked TypeScript source code for Anthropic's Claude Code CLI.
"The README file even claims the code was exposed through a .map file in the npm package and then rebuilt into a working fork with 'unlocked' enterprise features and no message limits," the security sleuths said in a Thursday blog.
They added that the GitHub repository link appeared near the top of Google results for searches like "leaked Claude Code." While that was no longer the case at The Register's time of publication, at least two of the developer's trojanized Claude Code source leak repos remained on GitHub, and one of them had 793 forks and 564 stars.
[...] In March, security shop Huntress warned about a similar malware campaign using OpenClaw, the already risky AI agent platform, as a GitHub lure to deliver the same two payloads.
Both of these illustrate how quickly criminals move to take a buzzy new product or news event (like OpenClaw and the Claude Code leak) and then abuse it for online scams and financial gain. "That kind of rapid movement increases the chance of opportunistic compromise, especially through trojanized repositories," the Zscaler team wrote.
The blog also includes a list of indicators of compromise, including the GitHub repositories with the trojanized Claude Code leak and malware hashes to help defenders in their threat-hunting efforts, so be sure to check that out - and, as always, be careful what you download. ®
New fossils from the Ediacaran Period show that some animal groups are older than we thought:
More than 539 million years ago, soft, clarinet-shaped animals anchored themselves to the seafloor on disc-shaped bases, swaying alongside stalked animals resembling worms and baskets. These woodwindlike creatures are just a few of those coming to life from a treasure trove of newly discovered fossils in southwestern China.
It’s surprising to see some of these weird creatures this far back in the fossil record, and their discovery is unearthing crucial new details about one of the most notable explosions in the diversity of animals in fossil history, researchers report April 2 in Science.
“This paper is absolutely fascinating,” says paleontologist Emily Mitchell at the University of Cambridge. “It provides vital insights into life around the end of the Ediacaran Period.”
The Ediacaran preceded a pivotal moment in animal prehistory called the Cambrian explosion, which started around 539 million years ago and marked a dramatic and rapid diversification, an “explosion” of physical forms and complexity. How that explosion happened isn’t clear. Fossils from the late Ediacaran Period, from 575 million to 539 million years ago, show this is when the first unambiguous animal fossils appear but don’t offer many details about the animals’ bodies or biology. Many of the Cambrian animal groups also do not appear in the Ediacaran record, suggesting that Cambrian animal diversity may have exploded from only a small number of species.
Now, a new trove of fossil specimens collected near Jiangcheng, China, is challenging that idea.
[...] Among the more eyebrow-raising findings were the animals with bilateral symmetry — similar features on the right and left sides. Fossilized bodies of bilaterians this early is rare, with only four species known from the Ediacaran until now. Li and the team found more than 180 bugle worm fossils, along with fossils of other bilaterial creatures, including those that looked like sausages on skewers, with feathery appendages around their mouth ends.
Emmy Smith, a paleontologist at Johns Hopkins University in Baltimore, was struck by the abundance and diversity of bilaterian fossil finds. Many of these show structures specialized for feeding. These weren’t simple progenitors of later lineages; these animals were already quite physically complex, she says. “That strengthens the view that major animal lineages were already diversifying before the Cambrian.”
The results suggest the explosion of animal diversity in the Cambrian didn’t appear out of nowhere, Li says. Instead, a gradual buildup of complex animal life was underway millions of years before.

AMD aims to extend its lead in desktop gaming with a new CPU, dubbed the Ryzen 9 9950X3D2 Dual Edition. This top-of-the-line part has 16 cores fed by an absolutely massive 208 MB pool of cache, with memory spread across both CCDs.
The hotly anticipated processor chip is essentially a modified version of the 9950X3D announced in 2025, only both of the chip's two compute dies are now equipped with a 64 MB SRAM tile, boosting the L3 cache from 128 MB to 192 MB.
Larger caches benefit data heavy workloads, in particular PC games, by keeping more of the working memory closer to the cores. Since the launch of the Ryzen 7 5800X3D in 2022, AMD has used advanced packing to expand its chips' L3 cache without needing to design a larger die. This technology helped AMD to overtake long-time rival Intel in gaming CPU performance.
While 3D V-Cache's most obvious benefits accrue to gamers, the additional cache also benefits a lot of high-powered production workloads, like 3D rendering, code compilation, AI, and data science because frequently accessed data can stay resident on the CPU for longer. (This is one of the reasons why caches of server CPUs have increased so dramatically over the past few years.)
[...] According to Jack Huynh, SVP of AMD's computing and graphics group, with the 9950X3D2, customers "no longer have to choose between a gaming or creator CPU."
[...] The 9950X3D2 is slated to hit store shelves on April 22. Pricing for the new part hasn't been released just yet, though with the 9950X3D currently retailing for north of $649, we don't expect it to be cheap.
This may make it tough to sell to gamers at a time when the memory, storage, and GPU prices are at an all-time high. AMD's decision to launch a new flagship in the current climate comes in stark contrast to Intel's newly-launched Core Ultra 200S Plus series processors, which we reviewed earlier this week, which promise 18 to 24 cores at a price ranging from $200-$300.
While AMD's X3D chips still hold the advantage in gaming, Intel's latest parts may see wider adoption because they're cheap and also perform exceptionally well in production workloads.
The science of smartphone addiction:
This is huge news, a landmark verdict that will inform hundreds of cases to come. While the plaintiff, a 20-year-old identified only as KGM, has been awarded $6m in damages, it's the verdict itself that's most damaging, as it opens the door to many more lawsuits against tech companies.
KGM's lawyers, in their closing remarks, said: “How do you make a child never put down the phone? That’s called the engineering of addiction. They engineered it, they put these features on the phones. These are Trojan horses: they look wonderful and great … but you invite them in and they take over.”
One literature review by Italian pediatrists linked digital addiction in children with depression, diet, and psychological issues, as well as 'sleep, addiction, anxiety, sex related issues, behavioral problems, body image, physical activity, online grooming, sight, headache, and dental care'. KGM was six years old when she first got addicted to social media, according to her testimony.
Researchers in Germany, Sweden, and the Netherlands have also linked 'high social media usage' among adolescents to 'a statistically significant change in the developmental trajectory of cerebellum volumes', a part of the brain associated with emotional control. It could literally influence the brain's physical development.
Another report says: "frequent social media use may be associated with distinct changes in the developing brain in the amygdala (important for emotional learning and behavior) and the prefrontal cortex (important for impulse control, emotional regulation, and moderating social behavior), and could increase sensitivity to social rewards and punishments".
However, it's worth noting that none of these findings are yet conclusive.
They're not entirely wrong. The basis of addiction is all about hijacking the 'mesolimbic system', the part of the brain responsible for associating certain behaviors with rewards, both natural (food, sex, play) and artificial (drugs such as alcohol and nicotine, and notifications). Once a reward is achieved, dopamine is released.
One study on teen addiction linked activation of the mesolimbic pathway to social media use, stating children are "often victims of an unrelenting 'dopamine cycle' created in a loop of 'desire' induced by endless social media feeds, 'seeking and anticipating rewards' in the way of photo tagging, likes, and comments," the latter being the triggers that continue to reinstate the 'desire' behavior.
"The overactivation of the dopamine system in such individuals can further increase the risk of addictive behaviors or pathological changes that lead to a decline in pleasure from natural rewards." Essentially, all you want to do is keep scrolling, just like an addict looking for an endless fix because natural rewards no longer provide the same pleasure as scrolling.
According to CNN, KGM's lawyer Mark Lanier said in his opening statement: “This case is about two of the richest corporations who have engineered addiction in children’s brains,” Lanier said in his opening statement. “The swipe, for a child, like Kaley, this motion is a handle of a slot machine. But every time she swipes, it’s not for money, but for mental stimulation.”
KGM's lawyers mention the infinitely scrollable feeds and video autoplay as features designed to keep people on the apps, maintain attention, and encourage addictive behaviors. But it's ok, because the inventor of the scrollable feed, Aza Raskin, apologized when he unleashed this horror upon the world.
Combine this with the infinitely scrollable feed and addictive, casino-esque nature of social media platforms, and you get doomscrolling, a constant stream of bad news, enraging user-created content, and messaging that you're never going to be enough unless you do this, or buy that, or look like this.
[...] The bottom line? Children are easily impressionable, and if online negativity is more rewarding than positivity, unfettered access to an endless stream of content designed to make users feel worse to increase engagement is going to warp their worldview. According to the jury, in this case, the buck stops at the algorithm's designers.
'Shockingly bad': Nissan Leaf drivers voice anger over app shutdown:
Owners of some Nissan Leaf electric vehicles are angry after the carmaker announced it would shut down an app that lets them remotely control battery charging and other functions.
Drivers of Leaf cars made before May 2019 and the e-NV200 van (produced until 2022) have been told that the NissanConnect EV app linked to their vehicles will "cease operation" from 30 March. This means they will lose remote services, including turning on the heating, and some map features.
Experts said they expected other drivers to experience similar problems in future as "connected cars" – vehicles that can connect to the internet – get older.
One driver and Guardian Money reader, Alan Clucas, said he was upset by the switch-off, adding that some of the affected vehicles were less than four years old. "I think Nissan should do better," he said.
Talking about his seven-year-old Leaf, Clucas said the "most annoying thing will be not being able to smart-charge the car or remotely warm it up on frosty mornings". He added: "We could previously check the charge levels from a mobile phone."
Other affected motorists have been discussing the matter online. "Looks like going forward, only paid-for remote connectivity will be supported," said one, adding that it was "amazing" that Nissan "only supported a core EV feature for seven years. Considering [an] average car can last for 12-plus years, that is shockingly bad."
Another driver added: "My car is almost 10 years old now, but those with an early 2020 model won't be too happy that their not-even seven-year-old car is having remote access removed with a month's notice."
Nissan faced criticism in 2024 when it dropped the first generation of Leaf cars after the switch-off of the UK's 2G network. The carmaker said the latest move was because the app could not be "upgraded to support future enhancements".
In-car services such as climate control and charging timers would still be available through the infotainment system, Nissan said, but remote services and some map-related features would not.
Steve Walker from the motoring magazine Auto Express said the situation was a preview of what would happen when "today's cars" get old.
"As modern cars that are even more reliant on connected services and updates than the Leaf age, it is likely that manufacturer support for their systems will drop away, too," he said.
This could mean other features including navigation systems, touchscreen controls and even subscriptions for features such as heated seats, autonomous driving aids or extra engine power could stop working or be turned off further down the line, he said.
"Nobody wants to see cars rendered obsolete before their time," Walker said. "The best way to minimise the environmental impact of cars is to build them to last. Software and digital systems need to be as durable and reliable as mechanical components."
Benjamin Gorman, a senior lecturer at Bournemouth University, said the tech world was shifting towards software-as-a service (Saas) models.
"A good example is software like Adobe Photoshop – historically, you could buy it once and use it for as long as you liked, whereas now it typically requires an ongoing subscription," said Gorman.
This worked well for things such as games and entertainment platforms, where people are used to subscriptions and shorter upgrade cycles, he said. However, it is more problematic when applied to expensive physical products such as cars, which people expect to keep working for a decade or more.
"I suspect we will see this issue more often in the coming years as vehicles become increasingly software-driven," said Gorman. "We are seeing more manufacturers experiment with subscription fees for connected features ... but it raises important questions about what consumers feel they should permanently own versus what they are effectively renting through software services."
The data centers at the heart of the AI boom are producing so much heat that they're spiking land temperatures for miles around them by up to 16 degrees Fahrenheit, new research suggests. The effect is so pronounced that the researchers say they're creating entire "heat islands:"
The data centers at the heart of the AI boom are producing so much heat that they're spiking land temperatures for miles around them by up to 16 degrees Fahrenheit, new research suggests. The effect is so pronounced that the researchers say they're creating entire "heat islands."
The findings, detailed in a study that's yet-to-be-peer-reviewed, add to an already grim picture of the environmental impact of these sprawling facilities, the largest of which consume enough energy to power entire cities. Their commensurate greenhouse gas emissions, however, apparently aren't the only way data centers are heating up the world around them.
The researchers focused on roughly 8,400 so-called "hyperscalers," the term used to describe data centers of incredible size that offer cloud computing and AI services. Their construction has surged in the past decade, and the AI boom has pushed their demand and scope to new heights; Meta's new "Hyperion" data center, for example, cost $27 billion to build and has an expected computing capacity of five gigawatts, an appetite that takes ten gas-powered plants to sate.
[...] The effects were local, but far reaching. The researchers found that the temperature increases were felt up to 6.2 miles away — though they dropped off with distance — in all affecting more than 340 million people. CNN's coverage notes that the trend held globally: Mexico's burgeoning data center hub in Bajio saw an uptick of around 3.6 degrees over the past 20 years, as did Aragon, Spain, itself a hot new hub for hyperscalers.

Computer security boffins have conducted an analysis of 10 million websites and found almost 2,000 API credentials strewn across 10,000 webpages.
The researchers detail their findings in a preprint paper titled "Keys on Doormats: Exposed API Credentials on the Web," and say they conducted the study because much of the attention on exposed credentials has focused on scouring code repositories and source code. They argue that dynamic analysis of production websites is essential to understand the scope of the problem.
"What we found were highly sensitive API credentials left publicly exposed on public webpages," Nurullah Demir, a PhD candidate at Stanford and corresponding author, told The Register in an email. "These act as access tokens that authorize applications to interact with third-party services, granting direct access to critical infrastructure like cloud platforms and payment providers."
Demir contends that API credentials are even more dangerous than exposed login details because they provide programmatic access to resources.
The researchers scanned approximately 10 million websites using a tool called TruffleHog, and found 1,748 valid credentials belonging to organizations including multinational corporations, critical infrastructure entities, and government agencies. The keys provide access to services like AWS, GitHub, Stripe, and OpenAI.
Demir said one of the affected organizations was a global bank. Another makes firmware for electronic devices.
"A 'Global Systemically Important Financial Institution' exposed its cloud credentials directly on its webpages," said Demir. "This gave direct access to multiple core cloud infrastructure services, including databases and key management systems."
The researchers also found repository credentials for a developer responsible for firmware used by various manufacturers of drones and remote-controlled devices. Attackers could use those credentials to modify source code and push malicious firmware updates to various devices, Demir said.
"Exposure is widespread across service categories, with cloud services (e.g., AWS, Cloudflare) and payment services (e.g., Stripe, Razorpay) accounting for the majority of verified credentials," the paper explains. "AWS credentials alone represent more than 16 percent of all verified exposures and were found on over 4,693 websites. Email and communication services such as SendGrid and Twilio also appear frequently, with a significant portion of their exposures originating from embedded third-party resources."
Most of the credentials the researchers found were present in JavaScript resources (84 percent), followed by HTML (eight percent) and JSON (seven percent) files. They also turned up unusual cases like a verified GitHub access token embedded in a CSS file.
In JavaScript files, 62 percent of credential exposures show up in bundles created by build tools like Webpack.
Demir said he and his co-authors – Yash Vekaria of UC Davis, Georgios Smaragdakis from TU Delft/Stanford, and Zakir Durumeric from Stanford – made a significant effort to contact affected organizations. The number of exposed credentials declined by half in about two weeks after the researchers started to report their findings.
"When we got feedback from the developers, we saw that a significant number of them were completely unaware of the exposures," he explained. "What is perhaps most concerning is that our historical analysis showed these credentials often remain exposed for an average of 12 months, in some cases for years."
Demir said that he and his co-authors only verified credentials for 14 different service providers, so the exposure figure represents a lower bound.
"We strongly believe that the actual number of exposed credentials across the web is much higher than what we captured in this study," he said. ®
https://linuxiac.com/vitruvianos-0-3-debuts-as-haiku-inspired-linux-os/
VitruvianOS 0.3 has been released as the project’s first publicly available version, described by its developers as a pilot build. It is based on the Linux kernel and adopts a design inspired by Haiku OS and BeOS.
For reference, VitruvianOS’s development began in 2019, and now, in 2026, this version serves more as a functional foundation rather than a complete system. But before we go further, a few words about the project itself, since the name is probably unfamiliar to the general public.
VitruvianOS is not a Linux distribution in the usual sense. It uses the Linux kernel only for hardware support, while replacing the standard Linux userland and desktop stack with its own components. Its goal is to combine Linux compatibility with a BeOS-style architecture.
Let me explain. In a typical Linux desktop system, applications run on top of libraries and a display server such as X11 or Wayland. However, VitruvianOS removes this entire layer. It does not use X11 nor Wayland. Instead, it implements its own graphics system, input handling, and application runtime.
A key feature is Nexus, an internal communication layer that manages messaging between system components.
The system features native desktop elements modeled after BeOS, including a Deskbar and a Tracker-style file manager. It also offers a compatibility layer to support applications built for Haiku and BeOS APIs.
Moreover, the system uses a Linux kernel with real-time patches. Regarding filesystems, VitruvianOS 0.3 supports XFS and SquashFS, as well as extended attributes.
In the announcement, the developers have also outlined a short-term roadmap. Version 0.3.1 will add missing components and bug fixes based on initial testing. Version 0.3.2 aims to move the system toward self-hosting, enabling VitruvianOS to build itself.
Next, the upcoming 0.4 release will focus on stability and broader hardware support, including ongoing ARM port development. Planned improvements also include enhanced input handling, a complete keymap system, and further user interface refinements.
For more details, see the announcement.
Finally, once again: keep in mind that VitruvianOS 0.3 is an experimental release intended mainly for testing and development.

UL's Dr Kyriakos Kourousis discusses his current research in metal additive manufacturing and the work of the Metal Plasticity and Additive Manufacturing Group at UL.
Dr Kyriakos Kourousis is an associate professor in aeronautical engineering at University of Limerick (UL), as well as director of postgraduate research and education for the university’s Faculty of Science & Engineering. He also leads UL’s Metal Plasticity and Additive Manufacturing Group.
Kourousis joined UL’s School of Engineering 12 years ago, and before his career in academia, he spent more than a decade as an aeronautical engineer in the Hellenic Air Force working on aircraft maintenance, airworthiness and structural integrity – experience that he says now shapes his research and teaching.
At UL, he teaches topics around aircraft systems, the airworthiness of aircraft and the practical engineering behind them.
In terms of his current research, Kourousis says his work focuses on two things: how metals behave when they are loaded in a repeated way, leading to permanent deformation – “what engineers call metal plasticity” – and how to make and trust 3D‑printed metal parts (metal additive manufacturing), “especially for those loading conditions that cause plasticity”.
“In simple terms, we test metals, study their microstructure, build computer models that predict how they’ll perform over time, and use those models to predict how permanent deformation builds up during their operation,” he tells SiliconRepublic.com.
“Localised permanent deformation (plasticity) is the origin of fatigue in metals. My work is both on traditional metals and 3D‑printed ones.”
Here, Kourousis tells us about his work and provides a look into the world of 3D-printed materials and aeronautical engineering.
As 3D‑printed metal parts move from prototypes to real aircraft and machinery, we need to predict their behaviour with confidence. Experimental data and models help engineers design parts that won’t crack or fail early, and help industry and regulators build the evidence needed for certification. In short, better predictions mean safer, lighter, more efficient products.
Also, from a sustainability point of view, the use and reuse of powder in metal additive manufacturing offers an important advantage over other (traditional) manufacturing processes. However, with each reuse cycle, the recycled powder changes its synthesis and overall ‘quality’, which can have an effect on the produced parts, especially in terms of their plasticity behaviour.
One key finding is how directional 3D‑printed metals can be and what causes this directionality. For example, we showed that changing the build orientation and the post-3D printing processing of steel parts via heat treatments can noticeably change how it stretches and yields. We saw similar effects in 3D-printed titanium, in particular Ti‑6Al‑4V, which is widely used in the aerospace and biomedical industries.
We’ve also found that even lower‑cost metal 3D printing routes (like material‑extrusion/fused filament fabrication) show clear links between print settings and mechanical performance, useful for small/medium companies exploring affordable metal additive manufacturing.
3D‑printed metals aren’t ‘just like’ traditional (wrought) metals. The layer‑by‑layer process creates a directional ‘grain’, so properties change with build direction, clearly shown in our work on steel and titanium. Process signatures matter. Printing can leave tiny pores (lack‑of‑fusion or keyhole) and locked‑in residual stresses; tuning scan strategy and energy helps, but these features still drive plasticity and fatigue if not managed.
An interesting debate I have with colleagues working in material science is that 3D-printed material may appear as having uniform features in the microscale, but the higher scale defects caused by the melting-solidification and re-melting can lead to a quite non-homogeneous part with differing mechanical properties at different loading directions (mechanical anisotropy).
Post‑processing can close the loop. Ageing/stress‑relief and especially hot isostatic pressing (HIP) homogenise the microstructure and seal pores, boosting ductility and fatigue, though outcomes depend on the as‑built quality and the budget available. A key target for the manufacturing industry is to make 3D printing not only accurate and consistent but also affordable, and we see that there is more work that has to be done there.
The big shift is the coming‑together of accessible metal 3D‑printing equipment with advanced, physics‑based modelling.
At UL, a milestone was obtaining a GE Concept Laser Mlab Cusing R metal 3D printer through a GE Additive award. Unlike other institutions in Ireland, our 3D printer is hosted within an industrial environment, through a collaborative agreement with our partner, Croom Medical. Our students and researchers can test ideas under realistic conditions, while both UL and Croom Medical leverage the advantages of this strategic partnership.
Our research group leads the metal additive manufacturing research activity in UL.
Our work is built around two main strands: metal plasticity modelling, where we turn lab data into reliable models of how metals actually deform; and metal additive manufacturing, where we study and improve metals such as titanium and steel, translating the results into practical build and heat‑treatment guidelines. Current projects and student work span physics‑informed yield prediction for steel 316L, laser powder bed fusion (the most widely used additive manufacturing method for metals) process optimisation, and corrosion-cyclic plasticity topics for aerospace‑grade alloys.
An interesting recent work involved showing that, by carefully retuning laser power, scan speed and hatch spacing, we can shift from the usual thin‑layer settings to much thicker layers in laser powder bed fusion of aerospace‑grade titanium, while keeping the process stable and parts dense. Led by one of our doctoral researchers who also works with Croom Medical, the study showed that those thicker‑layer builds delivered strength and ductility on a par with conventional settings, indicating that productivity can rise without an automatic hit to material performance.
Most importantly, after standard vacuum heat treatment and hot‑isostatic pressing, the parts satisfied the relevant industry standards, pointing to a practical path to higher throughput that still fits certification expectations.
On Wednesday, Apple unveiled new device-level age restrictions in the UK. After downloading a new update, users will now have to confirm that they are 18 or older to access unrestricted features.
Users will be able to confirm their age with a credit card or by scanning an ID.
For those underage or who have not confirmed their age, Apple will turn on Web Content Filter and Communication Safety, which will not only restrict access to certain apps or websites, but will also monitor messages, shared photo albums, AirDrop, and FaceTime calls for nudity.
Apple didn’t specify exactly which services and features are banned for under-18 users, but it will likely be in compliance with UK legislation. Gizmodo reached out to the Cupertino giant for comment, and we’ll update this post when we receive a reply.
The British government does not require Apple and other OS providers to institute device-level age checks, but it does restrict minor access to online pornography under the Online Safety Act, which passed in 2023. So far, that restriction has only been implemented at the website level, but UK officials have been worried about easy loopholes to evade the age restrictions, like VPNs.
The broader tech industry has been campaigning for some time to use device-level age checks instead in response to the rising tide of under-16 social media and internet bans around the world.
Last month, in a landmark social media trial in California, Meta CEO Mark Zuckerberg also supported this idea, saying that conducting age verification “at the level of the phone is just a lot clearer than having every single app out there have to do this separately.”
Pornhub-operator Aylo had advocated for device-level restrictions in the UK as well, and even sent out letters to Apple, Google, and Microsoft in November asking for OS-level age verification. At the time, British authorities had responded to Aylo, saying that OS-level restrictions would have to be industry-led, as nothing was stopping these tech companies from implementing the method and showing evidence of its effectiveness.
The most obvious question: Could this be brought stateside?
Many states have already passed legislation restricting the activity of minors on the internet. Apple began working with Texas authorities late last year on the state’s new age restrictions that have since drawn legal backlash. Last month, the company announced that new users in Utah and Louisiana will have their age categories shared with the App Store starting this summer, to ensure compliance with the new age restriction laws in the states.
The regulatory momentum is only growing in the United States, and states are increasingly seeking device-level restrictions. California passed its Digital Age Assurance Act last year, and the law would require users to enter their date of birth when setting up a new phone or computer to ensure OS-level restrictions when it goes into effect next year.
Colorado is also seeking to follow in California’s footsteps. Earlier this year, state legislators introduced a device-level age restriction bill modeled after California’s.
In space no one can hear you scream -- at Microsoft:
Many a frustrated user has sworn they'll launch Microsoft Outlook into space, but NASA has actually done it – on a journey around the Moon, where it's now causing problems for astronauts.
The astronauts aboard the Orion spacecraft currently circling the Earth are taking care of a bunch of housekeeping tasks, including getting their devices working. Judging by some space-to-ground communications with controllers at Houston, it isn't going well.
NASA has helpfully provided a YouTube channel showing live views from the Orion spacecraft, as well as snippets of communication. During this stream, one of the astronauts can be heard first asking for help with network connectivity (IT support staff will be delighted to know that one troubleshooting step involves turning the device off and on) before telling controllers, "I have two Microsoft Outlooks, and neither one of those are working."
Multiple Outlooks is something that is all too familiar to many Windows users. A year ago, the acceptable face of development at Microsoft, Scott Hanselman, parodied the situation by listing some tongue-in-cheek variants to go with Outlook (Classic) and Outlook (New). How about Outlook (Zero Sugar), Outlook (Caffeine Free), and so on? The Orion 'nauts could well be looking at Outlook (Deep Space), Outlook (Low Earth Orbit), or even Outlook (Tentacle Edition).
And, for at least one of the four Artemis II crew members, none of the Outlooks is working.
Even if you go 384,000 km away, you still can't get away from your email.
Update: As of Saturday morning, Artemis 2 is now closer to the moon than it is to earth. [JR-04012026-0640utc]
Within hours of launching four astronauts on NASA's Artemis 2 mission around the moon, its crew reported a glitch in what may have been the most anticipated new creature comfort of their Orion spacecraft: their space toilet.
Artemis 2 mission specialist Christina Koch noted an issue starting up part of the Orion capsule's toilet — which NASA calls the Universal Waste Management System — that deals with urine collection.
"The toilet fan is reported to be jammed," NASA spokesperson Gary Jordan said during live mission commentary. "Now the ground teams are coming up with instructions on how to get into the fan and clear that area to revive the toilet for the mission."
Norm Knight, NASA's director of flight operations, told reporters here at the Kennedy Space Center that the malfunction was due to a controller issue on the toilet. But NASA confirmed astronauts could still use the space commode to poop, just not urinate, though engineers were working to restore it to full service.
"In the meantime they're getting their contingency — their backup waste management capabilities specifically for urine," Jordan said. "The fecal collection of the toilet, that specific capability, can still be used with the waste management system aboard Orion."

A few hours after Koch reported the toilet issue to Mission Control, flight controllers walked her through a series of steps to try and fix it."Houston, Integrity, good checkout," Koch said after trying the fix.
Then, some relieving news.
"Happy to report that toilet is go for use," Mission Control's Capcom Amy Dill radioed Koch. "We do recommend letting the system get to operating speed before donating fluid, and then letting it run a little bit after donation."
"We are cheers all around, and we will do that," Koch replied.
It does sound like at least one crewmember used a contingency bag before the fix. Koch reported that one CCU, or Collapsible Contingency Urinal, was full and needed to be emptied overboard. Dill radioed up instructions on the best time for that dump, and all was well.
That may be a relief for the Artemis 2 astronauts, in more ways than one. NASA's Apollo astronauts did not have the luxury of a toilet when they flew to the moon in the 1960s and 1970s. They peed and pooped in plastic bags, then stowed the solid waste and vented urine overboard into space.
The toilet aboard Orion is a smaller, more compact version of the bathrooms on the International Space Station. It's built into the floor of the Orion capsule and allows Artemis 2 astronauts some privacy while taking care of business. While the Orion spacecraft is larger than NASA's Apollo capsules, it's still cramped — the interior has been compared to that of two SUVs.
The global shortage of solid state memory has claimed its first photographic victim, as Sony has announced that it is suspending fulfillment of all orders for nearly its entire SD and CFexpress memory card product lines.
Sony Japan published the notice on its website today:
Thank you for your continued patronage of Sony products.
Due to the global shortage of semiconductors (memory) and other factors, it is anticipated that supply will not be able to meet demand for CFexpress memory cards and SD memory cards for the foreseeable future. Therefore, we have decided to temporarily suspend the acceptance of orders from our authorized dealers and from customers at the Sony Store from March 27, 2026 onwards.
Regarding the resumption of order acceptance, we will consider it while monitoring the supply situation and will announce it separately on the product information page.
GitHub will now use developer data to train its AI models by default:
GitHub has confirmed it will begin using developer interaction data to train its artificial intelligence models, marking a significant shift in how user data is handled across its platform.
The move, set to take effect on April 24, introduces an opt-out system, meaning most users will be automatically enrolled unless they explicitly disable the setting.
The Microsoft-owned platform said it will start collecting and using interaction data from its AI coding assistant, GitHub Copilot, to improve model performance.
This includes:
- Code snippets entered by users
- Prompts and inputs
- AI-generated outputs and edits
- Context such as file structure and repository data
- User feedback like ratings and interactions
GitHub says this data will help build "more intelligent, context-aware" coding tools and improve accuracy across different programming languages and workflows.
[...] Users who do not want their data used for training must manually disable the setting in their account preferences.
However, enterprise-focused tiers including Copilot Business and Enterprise are excluded from the change, reflecting stricter data governance expectations in corporate environments.
GitHub says real-world developer interactions are essential to improving AI systems.
