A gray powder that looks like ash can become something closer to stone when hit with the right beam of light. Engineers have shown that simulated lunar soil can be melted and layered into solid shapes using a laser-based 3D printing technique, producing materials that tolerate heat and mechanical stress. The approach could help future astronauts build tools, landing pads, and habitat components directly on the Moon instead of hauling heavy supplies from Earth. The work, led by researchers at The Ohio State University and published in Acta Astronautica, focuses on a manufacturing strategy known as laser-directed energy deposition, or LDED. It involves feeding powdered material into a laser-generated melt pool,...

Le président américain annonce que les frappes en Iran continueront « sans interruption tout au long de la semaine ».

The supreme leader of Iran embraced hardline policies against increasing pressure for reform.

The excess of politicians' children was front and centre of the anger that drove protests that toppled the government last year.

Has Donald Trump brought about Claudemania?

WIRED has reviewed hundreds of posts on X that promote misleading claims about the locations and scale of the attack.

Le numéro 1 du régime iranien, l’ayatollah Ali Khamenei, figure incontournable de la République islamique, aurait été tué ce samedi 28 février, selon des responsables israéliens, cités par plusieurs médias.

It looks like a user error with the Amazon Polly text-to-speech system is to blame.

A Norwegian eighth-grader can feel like they’re doing fine at school, safe enough in the hallways, and still carry a quiet story about themselves that shifts depending on whether they are a boy or a girl. It’s not just about grades. It’s about the inner stuff: confidence, persistence, kindness toward yourself, and how much support you think you’re getting from the people around you. In a large survey of Year 8 pupils, boys tended to rate themselves higher on most measures tied to motivation and school experience. Girls stood out in a different way, scoring much higher on compassion for others and slightly higher on the compassion they felt they received. That mix matters because the same traits that...

The European football association (UEFA) protects the multi-billion-dollar interests of European football around the globe. To better protect its content, including the prestigious Champions League competition, it joined the Alliance of Creativity and Entertainment (ACE) last October. At the time, it seemed likely that the anti-piracy group could help UEFA with their international site-blocking quests. While the organizations did not confirm this at the time, this is precisely what happened.
UEFA Secures Broad Blocking Order
Earlier this month, UEFA obtained a new injunction at the High Court of Delhi. The order was obtained in cooperation with ACE and targets 79 live sports streaming sites, aiming to protect...

Everyone is probably familiar with the concept of battery-powered devices, but generally, this involves a laptop with a beefy battery pack and hardware optimized for low power draw. You could also do the complete opposite and try to run a desktop PC off alkaline AA cells, as [ScuffedBits] recently did out of morbid curiosity. Exactly how many alkaline cells does it take to run a desktop PC for any reasonable amount of time?
One nice thing about using batteries with a desktop PC is that you can ditch the entire AC-DC power conversion step and instead use a DC-DC adapter like the well-known PicoATX and its many clones. These just take in 12 VDC and tend to have a fairly wide input voltage range, which is useful...

It might be World War III, but at least I won $20. | Image: Polymarket / The Verge Polymarket has been allowing people to bet on when the US would strike Iran next. Obviously, now that it's actually happened and people have died, the prediction betting market is feeling some pressure. The site has been at the center of controversy before, including suspicions of insider trading on the Super Bowl halftime show and the capture of Venezuelan President Nicolás Maduro.
In a statement posted on its site, Polymarket defended its decision to allow betting on the potential start of a war, saying that it was an "invaluable" source of news and answers, before taking shots at traditional media and Elon Musk's X. The...

So called "pig butchering" scams are happening on an industrial scale. Politicians have noticed.

The U.S. and Israel have ignited a campaign to topple the Islamic Republic—with little thought to what comes after.

And the risks Democrats face if they fail to strongly oppose his war.

Iran's strike on US Navy base in Bahrain will worry Washington and its allies in the region.

That’s coming on a little strong, maybe. | Image: Vera C. Rubin Observatory The Vera C. Rubin Observatory's automated alert system is online and already bombarding astronomers with things to look at in the night sky. The system went live publicly on Tuesday, February 24th, and on the first night dropped some 800,000 alerts about asteroids, supernovas, and feasting black holes. And that number is only expected to climb to the multiple millions per night.
The observatory released the first images taken with its car-sized Legacy Survey of Space and Time (LSST) camera in June of last year. But researchers and stargazers have been eagerly anticipating the launch of this system. Every night, the camera captures...

Farmers have long fought a quiet war against the fungi that rot crops in fields and storage sheds. Each year, these diseases destroy harvests of lettuce, beans, oilseed rape, wheat, and many other staples. The usual defense relies on synthetic fungicides, but those chemicals face rising costs, tighter rules, and growing concern about environmental harm. Now, new research suggests that help may come from an unexpected ally already living in the soil. Scientists at Rothamsted, working with partners at the Universities of Warwick and Exeter, have discovered that a common soil fungus, Trichoderma hamatum, can release natural airborne chemicals that slow or stop dangerous crop diseases. The study, published this...

Les vidéos vérifiées par « Le Monde » révèlent l’ampleur de l’attaque lancée par les Etats-Unis et Israël et de la riposte du régime iranien. Les images confirment que de nombreuses cibles ont été touchées.

Smoke and flames rose from Dubai's Fairmont The Palm hotel as civilian targets came under fire along with the US military bases across the Middle East.

As temperatures warm up in the Northern Hemisphere, one’s mind naturally turns to the outdoors and the garden — even if some of our gardens are still snow-covered. One secret to good gardening is that many of the plants we love take too long to grow if started from seed outside, at least in relatively temperate climes. There are a myriad of ways to grow seedlings indoors, and this new hack highlighted by [GrowVeg] looks like a great way to get started.
The idea apparently comes from the seedier side of Instagram, where [Farida Sober] has been popularizing it as a “seed snail”, a name they seem to have coined. The technique is very simple: take a sheet of something cheap that won’t disintegrate when...

Les États-Unis et Israël ont lancé une vague d’attaques contre l’Iran samedi 28 février. Téhéran a riposté en lançant des dizaines de drones et missiles en direction d’Israël mais aussi des pétromonarchies du Golfe. Dans la soirée, des sources israéliennes ont annoncé que le Guide suprême, l’ayatollah Khamenei, avait été tué. La presse étrangère redoute un embrasement régional. Retour sur le premier jour de la guerre en cinq articles.

Condamnations des attaques, appels au respect du droit international : les réactions des dirigeants se sont multipliées aux quatre coins de la planète après les frappes menées par les États-Unis et Israël contre l’Iran, suivie de la riposte iranienne, samedi 28 février.

La stratégie du couple américano-israélien est de contraindre le régime iranien à changer de trajectoire, à accepter une forme de capitulation ou à être renversé de l’intérieur. Mais plusieurs questions restent en suspens, analyse le corédacteur en chef du quotidien “L’Orient-Le Jour”.

In one room, an adult caregiver paced around, patting their pockets and peeking underneath furniture. This indicated they were looking for something that was no longer there. Nearby, a dog observed closely before trotting to a cabinet shelf. Then it turned back to the caregiver, as if attempting to assist in locating the lost item. A cat observed everything happening as well, but tended to remain close to where it originally sat. It was just as observant. Many pet owners have likely encountered this difference in temperament between dogs and cats. Recent scientific studies confirm these observations experimentally. Scientists at Eötvös Loránd University and HUN-REN–ELTE in Hungary compared how...

Josyane Savigneau, ancienne responsable du « Monde des Livres », retrace la relation singulière qu’elle a entretenue avec l’écrivain américain pendant vingt-cinq ans. Leur première rencontre, en 1992, lors d’un entretien pour « Le Monde », avait pourtant été « assez rude ». Néanmoins, au fil du temps et au-delà des frontières professionnelles et culturelles, une véritable amitié s’est nouée.

Alors que des élections législatives doivent se tenir d’ici à octobre, les opposants au gouvernement de Benyamin Nétanyahou ont exprimé samedi leur appui à l’opération conjointe avec les Etats-Unis contre le régime de Téhéran. L’opinion publique aussi était prête à une nouvelle offensive.

Welcome to the weekend, friends! While the rest of our team was checking out Samsung’s forthcoming Galaxy S26 lineup and prepping for Apple’s “special experience” next week, we’ve been sifting through Woot’s “Video Games for All” sale and a truly weird slate of deals that, frankly, don’t have a throughline. (Some of us have also spent the last week unpacking what Huel is, but that’s neither here nor there.) Here’s what we can tell you. If you’re thinking of picking up the Galaxy S26 Ultra at launch, putting in your preorder now isn’t a bad idea. It’s also a great time to pick up the midrange QuietComfort Headphones and what many of us at The Verge consider to be the game of 2024:...

America’s journey back to the moon has run into a few missteps. NASA administrator Jared Isaacman is banking on a new approach.

Iranians talk about what is happening inside the country, despite an almost total internet blackout.

As Iranian missiles targeted US-linked sites across the Gulf, the UAE’s missile shield was activated in real time.

Tardigrades have a reputation for being nearly indestructible. These microscopic animals, often nicknamed water bears, can dry out and slip into a dormant state. This state helps them survive the vacuum of space, deep-sea pressures, and punishing cold. That track record makes them tempting stand-ins for a bigger question that hangs over future Mars missions. What happens when Earth life meets Martian soil? In a new set of experiments using Mars regolith simulants, researchers found that some “Mars dirt” was harsh enough to shut down active tardigrades within days. One simulant proved especially damaging. Yet, a simple rinse with water largely removed the problem. The work, co-led by Corien Bakermans, a...

Al and I were talking on the podcast today about a sweet 3D printed wide-format camera build, and we got to musing on why we 3D-print.
For Al, it’s an opportunity to experiment with 3D printing itself: tweaking his machines to get the best performance out of them. Other people make small, functional objects that they need in their daily life, like bag clips or spare parts for broken appliances. Some folks go for the ornamental or the aesthetic. The kids in my son’s class all seem obsessed with sci-fi props and fidget toys. The initial RepRap ideal was to replace all commercial fabrication with machines owned by the individual, rather than by companies – it was going to be Marxist revolutionary.

The latest Xiaomi flagship is a beast and comes in a specially co-designed Leica edition that’s picture-perfect.

The Leitzphone has just launched internationally alongside a regular version of the 17 Ultra. Xiaomi and Leica's long-running phone partnership just got a little closer. Alongside the new international release of its 17 Ultra flagship, Xiaomi has been entrusted with manufacturing a separate version that is the first Leica Leitzphone to release outside of Japan, following three Sharp-made models exclusive to the country.
In truth, the Leitzphone is a 17 Ultra with Leica branding and a rotatable camera ring, and apart from a few design tweaks, it's mostly the same as the Leica Edition of that phone already available in China. But the branding is a big deal: Leica hasn't let Xiaomi use its red dot logo on...

The Xiaomi Tag is a bit larger than Apple’s second-gen AirTags. | Image: Xiaomi Xiaomi has announced its first Bluetooth tracker, and while the Xiaomi Tag has a more elongated design than the Apple AirTag, that lets you use it in more places right out of the box. On one end of the tracker you'll find an integrated metal loop that can be attached to a keyring or clipped to a carabiner without the need for an extra case.
The Xiaomi Tag is compatible with both Apple's Find My and Google's Find Hub tracking networks and mobile apps, but not at the same time. You'll need to choose one or the other during setup. Like Apple's AirTag, the Xiaomi Tag is powered by a replaceable CR2032 coin cell battery good for up to...

MRI machines come with a variety of safety warnings. Perhaps most importantly, you have to be very careful not to take ferrous metal objects anywhere near them, since strong magnetic fields can send them flying, causing damage and injuries. To that end, you might find yourself in need of magnetically-safe tools when working on such machines. [Sam Schmitz] recently whipped up a nifty example of an MRI-safe torque wrench himself.
The torque wrench mechanism, which operates in one direction only.
It’s a 3D printed design which can be produced on a Formlabs Fuse 1+ as a single piece in nylon using a selective laser sintering process. The torque wrench works in a deceptively simple manner. As the handle is...

Sodium Chloride has a melting point of 801 C (1,474 F), putting it comfortably between commonly-cast materials like aluminum and bronze. Which led to [Robinson Foundry] asking the question: can you cast salt like a metal? The answer, surprisingly, was yes!
[Robinson] tries casting the salt with two different methods: like it was glass, and like it was metal. In the glass-like casting, he packs a ceramic mold with salt and tosses it into an electric kiln, there to melt and very slowly cool. In metal-like casting, he just tosses salt into a crucible and melts it in the same beer-can kiln we saw when we featured his lost-pla casting a while back. The molten salt is poured very carefully into sand casting molds....

Dans le juste milieu démocratique et pro-européen allemand, une explication courante de la montée de l'Alternative pour l'Allemagne (AfD) consiste à considérer ses électeurs comme des enfants peu instruits : dépourvus de réelle capacité d'action politique, sensibles à la rhétorique la plus élémentaire et votant sur la base d'émotions irrationnelles. Si l'on adhère à cette lecture, la solution logique serait alors de simplement mieux expliquer ses propres politiques. En pratique, cela a conduit à une rhétorique encore plus simpliste que celle dont leurs adversaires les accusent. Le Parti social-démocrate d'Allemagne (SPD), autrefois représentant de la classe ouvrière, est aujourd'hui le...
