First Petawatt Electron Beam Arrives, Ready To Rip Apart Matter and Space

Petawatt lasers have already allowed scientists to “manipulate materials in new ways, emulate the conditions inside planets, and even split atoms,” reports Science magazine. “Now, accelerator physicists have matched that feat, producing petawatt pulses of electrons that could also have spectacular applications…”

Described in a paper published Thursday in Physical Review Letters, the electron pulses last one-quadrillionth of a second but carry 100 kiloamps of current. “It’s a supercool experiment,” says Sergei Nagaitsev, an accelerator physicist at Brookhaven National Laboratory who was not involved in the work. Richard D’Arcy, a plasma accelerator physicist at the University of Oxford, adds, “It’s not just an experimental demonstration of something interesting, it’s a steppingstone on the way to megaamp beams.” If achievable, those even more powerful beams might begin to perform extraordinary feats such as ripping particles out of empty space, he says…

[A]mped-up lasers would open the way to, for example, probing chemical processes as they happen, says Sergei Nagaitsev [an accelerator physicist at Brookhaven National Laboratory who was not involved in the experiment]. “These are the easy pickings.” An ultraintense electron pulse could also be used to generate plasmas like those seen in astrophysics, such as the jets of matter and radiation that shoot out of certain stellar explosions at near-light-speed. Researchers need only fire the electron beam into the right target. “This is a fantastic relativistic drill,” Ferrario says. “The interaction of this with matter could be very interesting.”

Superintense electron bunches might someday even probe the nature of empty space. They produce a hugely intense electric field, so if one of them were to collide with an ultraintense laser pulse, which also contains a huge electric field, it would expose space to an incredibly strong electrical polarization, D’Arcy notes. If that field is strong enough, it should begin to rip particle-antiparticle pairs out of the vacuum, a phenomenon predicted by quantum physics but never observed. “You can access areas of particle physics that are inaccessible elsewhere,” Darcy says.

The Xiaomi 15 Ultra is a Leica-powered photo showcase

Practically every flagship phone can take a great picture. But that hasn’t stopped Xiaomi from continuing its partnership with legendary camera maker Leica to produce a photo powerhouse in the new Xiaomi 15 Ultra.

Powered by a Snapdragon 8 Elite chip with up to 16GB of RAM and 1TB of storage, it goes without saying that the Xiaomi 15 Ultra has top-notch specs. It also has a huge 6,000 mAh battery, which is bigger than anything you get from Apple, Google or Samsung. Meanwhile, when it comes to charging, wired speeds go up to 90 watts or just a tad slower at 80 watts wirelessly, which is no mean feat. And unlike most phones sold in the US, it comes with a power adapter in the box.

Elsewhere, the 15 Ultra sports a gorgeous 6.7-inch AMOLED display with a 1-120Hz refresh rate and up to 3,200 nits of brightness. It’s also available in three colorways: a white model with an etched back, black with an almost rubbery textured finish and a special Silver Chrome edition that draws inspiration from some of Leica’s old-school cameras. I appreciate that the white model I tested features subtle swerves carved into its back that shine in the sunlight. But let’s be honest, that two-toned metal and black one is easily the most attractive of the bunch because it really leans into what this phone does best.

In back, there’s a massive circular camera module that normally I’m not a huge fan of when used on rival devices like the OnePlus 13. However, on this device, it’s more than just a showpiece because inside it is some serious photo hardware. The Ultra 15’s 23mm equivalent main camera uses a massive 1-inch 50-megapixel Sony sensor. Then, for stuff like expansive landscapes, there’s an f/2.2 50-MP ultrawide cam. But it doesn’t stop there because there’s not one but two zoom lenses: a 50MP midrange shooter with a 70mm focal length plus a super high-res 200MP periscope array with a 100mm focal length (which equates to a 4.7x optical zoom).

Now, I haven’t had a ton of time to fully put it through its paces, but from what I’ve seen so far, the Xiaomi Ultra 15 has one of the most well-rounded photo toolkits around. It’s got Leica optics along with big sensors and lenses that cover pretty much every focal length you’d need on a daily basis. And on the software side, there are some preset Leica filters like Vibrant or Authentic to really drive home the collaboration between the two brands.

That said, one of the things that impresses me the most is that Xiaomi even created a separate Photography kit that includes an add-on camera grip with a physical shutter button, an adjustable dial and a dedicated video button. There’s also a case that allows you to attach a standard 67mm filter adapter. This means, assuming you have the right gear, you can take some of the same glass you use on your real camera and use it with the Ultra 15. And this isn’t just some half-hearted afterthought either, as the kit also comes with bonuses like a hand strap, a decorative lens ring and two different removable caps for its shutter.

Notably, unlike some Chinese phones like those from Huawei, Xiaomi handsets still have access to Google services, so you can download apps from the Play Store. Even the company’s HyperOS 2 is a relatively minimalist Android skin that looks good and is easy to use. And while this model will be available globally starting at around €850, sadly there are no official plans to bring it to the US, which is a real shame because no one is really selling handsets like this in America anymore. (RIP to the Panasonic Lumix DMC-CM1.)

An small microbial ecosystem has formed on the International Space Station

Astronauts on the International Space Station often suffer from various immune system dysfunctions, including allergies and skin rashes, even though they go through rigorous screening and are probably among the healthiest people on (or at least near) Earth. “It’s hard to pinpoint the exact causes for a lot of these symptoms, but we believe microbiome disruptions that happen in their bodies and in their environment up there could be playing an important part”, says Rodolfo Salido Benitez, a bioengineering researcher at the University of California, San Diego who co-authored the largest study on the ISS microbiome to date.

After analyzing over 800 samples collected by astronauts in multiple modules of the United States Orbital Segment in the ISS, Benitez and his team concluded the microbial and chemical environment on the station closely resembled the one found at COVID-19 isolation wards during the height of the pandemic. And that may be less than ideal for keeping people healthy.

Swabbing the space decks

Monitoring microbial life on the ISS is an ongoing effort, and studies of this sort have been done before, although at a much smaller scale. “Previous studies used a low number of samples that could not identify all microbial and chemical factors present up there,” said Nina Zhao, a researcher at the UCSD and co-author of the study.

Malicious PyPI Package Exploited Deezer’s API, Orchestrates a Distributed Piracy Operation

A malicious PyPi package effectively turned its users’ systems “into an illicit network for facilitating bulk music downloads,” writes The Hacker News.

Though the package has been removed from PyPI, researchers at security platform Socket.dev say it enabled “coordinated, unauthorized music downloads from Deezer — a popular streaming service founded in France in 2007.”

Although automslc, which has been downloaded over 100,000 times, purports to offer music automation and metadata retrieval, it covertly bypasses Deezer’s access restrictions… The package is designed to log into Deezer, harvest track metadata, request full-length streaming URLs, and download complete audio files in clear violation of Deezer’s API terms… [I]t orchestrates a distributed piracy operation by leveraging both user-supplied and hardcoded Deezer credentials to create sessions with Deezer’s API. This approach enables full access to track metadata and the decryption tokens required to generate full-length track URLs.

Additionally, the package routinely communicates with a remote server… to update download statuses and submit metadata, thereby centralizing control and allowing the threat actor to monitor and coordinate the distributed downloading operation. In doing so, automslc exposes critical track details — including Deezer IDs, International Standard Recording Codes, track titles, and internal tokens like MD5_ORIGIN (a hash used in generating decryption URLs) — which, when collected en masse, can be used to reassemble full track URLs and facilitate unauthorized downloads…

Even if a user pays for access to the service, the content is licensed, not owned. The automslc package circumvents licensing restrictions by enabling downloads and potential redistribution, which is outside the bounds of fair use…
“The malicious package was initially published in 2019, and its popularity (over 100,000 downloads) indicates wide distribution…”

Driving an EV restomod that costs as much as a house—the JIA Chieftain

The Chieftain Range Rover is a fascinating thing—a refitted, reskinned, restored classic Range Rover is no new thing, nor is one with a ludicrous American V8 stuffed under the hood. But one that can be had as a gas car, plug-in hybrid, or as an EV? It can be all of those things depending on which boxes you tick. Ars Technica went for a spin in the EV to see how it stacks up.

The UK is something of an EV restomod hub. It’s been throwing electricity in things that didn’t come off the line electrified in the first place for years. Businesses like Electrogenic, Lunaz, and Everrati will, for a price, make an old car feel a little more peppy—depending on who you go to, it’ll come back restored as well. The Chieftain isn’t quite like them. Developed by Oxfordshire, UK, based Jensen International Automotive (the company’s bread ‘n butter is Jensen Interceptors), the Chieftain is an old Range Rover turned up to VERY LOUD. Or, actually, not loud at all.

Of course, these things come at a cost. A Chieftain EV Range Rover conversion, today, will set you back at least $568,000 should you choose to order one. This one was a private commission, and at that price there won’t be any built on spec on the off chance someone wants to buy one “off the peg.” By any stretch of the imagination it is a huge amount for an old car, but they’re custom-built from start to finish.

Driving the new Mercedes CLA made me a believer in Mercedes-Benz’s EV future

Mercedes-Benz’s EV efforts aren’t exactly burning up the sales charts. Models like the EQS and EQE haven’t convinced the brand’s demanding clientele that batteries are the future, forcing the company to scale back its electric ambitions.

Scale back, but not abandon. Benz is about to launch a new generation of EVs relying on technology derived from the epically efficient EQXX. The first is the new CLA. It’s coming soon, and after getting some time behind the wheel of a prototype vehicle undergoing final testing in the snowy wilds of Sweden, I’m convinced this could be the car to change Mercedes’ electrified fortunes.

And, for anyone who isn’t convinced, there’ll be a hybrid version too.

Watch ‘Blue Ghost’ Attempt Its Landing on the Moon

Watch the “Blue Ghost” lunar lander attempt its moon landing.

The actual landing is scheduled to happen at 3:34 a.m. Eastern time, according to CNN, while “The first images from the mission should be delivered about a half hour after…”
Success is not guaranteed… [B]roadly speaking, about half of all lunar landing attempts have ended in failure. Jason Kim, Firefly’s CEO, told CNN in December that his company’s experience building rockets has given him a high degree of confidence in Blue Ghost’s propulsion systems. “We’re using (reaction control system) thrusters that we’ve built, developed in-house, that are designed by the same people that design our rocket engines. That reduces risk,” Kim said. “All that gives us high confidence when we have people that do rocket engines really, really well — some of the best in the world.”

But the New York Times notes that Blue Ghost, built by Austin, Texas-based Firefly Aerospace, is just one of three robotic spacecraft “in space right now that are aiming to set down on the moon’s surface.”

Blue Ghost has performed nearly perfectly. For the first 25 days, it circled Earth as the company turned on and checked the spacecraft’s systems. It then fired its engine on a four-day journey toward the moon, entering orbit on February 13. The spacecraft’s cameras have recorded close-up views of the moon’s cratered surface…

On the same SpaceX Falcon 9 rocket that launched Blue Ghost to orbit was Resilience, a lunar lander built by Ispace of Japan. The two missions are separate, but Ispace, seeking a cheaper ride to space, had asked SpaceX for a rideshare, that is, hitching a ride as a secondary payload… Although Resilience launched at the same time as Blue Ghost, it is taking a longer, more fuel-efficient route to the moon and is expected to enter orbit around the moon in early May.

The third lunar lander heading to the moon is Athena (from Intuitive Machines), which launched Thursday on a SpaceX Falcon 9 rocket, “marking the first time humanity has had three lunar landers en route to the Moon at the same time,” according to a statement from the company. Space.com notes that “To date, just one private spacecraft has ever landed successfully on the moon — Intuitive Machines’ Odysseus, which did so in February 2024.”

Athena launched with several other spacecraft last night, including Odin, a scouting probe built by the asteroid-mining company Astroforge, and NASA’s water-hunting Lunar Trailblazer. Lunar Trailblazer is also moon-bound, though it’s headed for orbit rather than the surface…

27-Year-Old EXE Became Python In Minutes. Is AI-Assisted Reverse Engineering Next?

Adafruit managing director Phillip Torrone (also long-time Slashdot reader ptorrone) shared an interesting blog post. They’d spotted a Reddit post “detailing how someone took a 27-year-old visual basic EXE file, fed it to Claude 3.7, and watched as it reverse-engineered the program and rewrote it in Python.”

It was an old Visual Basic 4 program they had written in 1997. Running a VB4 exe in 2024 can be a real yak-shaving compatibility nightmare, chasing down outdated DLLs and messy workarounds. So! OP decided to upload the exe to Claude 3.7 with this request:
“Can you tell me how to get this file running? It’d be nice to convert it to Python.”>
Claude 3.7 analyzed the binary, extracted the VB ‘tokens’ (VB is not a fully-machine-code-compiled language which makes this task a lot easier than something from C/C++), identified UI elements, and even extracted sound files. Then, it generated a complete Python equivalent using Pygame. According to the author, the code worked on the first try and the entire process took less than five minutes…
Torrone speculates on what this might mean. “Old business applications and games could be modernized without needing the original source code… Tools like Claude might make decompilation and software archaeology a lot easier: proprietary binaries from dead platforms could get a new life in open-source too.”

And maybe Archive.org could even add an LLM “to do this on the fly!”

Utah Could Become America’s First State To Ban Fluoride In Public Water

NBC News reports that Utah could make history as America’s first state to ban fluoride in public water systems — even though major medical associations supporting water fluoridation:

If signed into law [by the governor], HB0081 would prevent any individual or political subdivision from adding fluoride “to water in or intended for public water systems…” A report published recently in JAMA Pediatrics found a statistically significant association between higher fluoride exposure and lower children’s IQ scores — but the researchers did not suggest that fluoride should be removed from drinking water. According to the report’s authors, most of the 74 studies they reviewed were low-quality and done in countries other than the United States, such as China, where fluoride levels tend to be much higher, the researchers noted.

An Australian study published last year found no link between early childhood exposure to fluoride and negative cognitive neurodevelopment. Researchers actually found a slightly higher IQ in kids who consistently drank fluoridated water. The levels in Australia are consistent with U.S. recommendations.

Major public health groups, including the American Academy of Pediatrics, the American Dental Association and the CDC — which says drinking fluoridated water keeps teeth strong and reduces cavities — support adding fluoride to water.

The article notes that since 2010 over 150 U.S. towns or counties have voted to keep fluoride out of public water systems or to stop adding it to their water (according to the anti-fluoride group “Fluoride Action Network”). But this week the American Dental Association (representing 159,000 members) urged Utah’s governor not to become ” the only state to end this preventive health practice that has been in place for over three quarters of a century.”

Microsoft Outage Leaves Tens of Thousands Unable to Access Email and Other Apps

“Tens of thousands of users were unable to access various Microsoft programs on Saturday afternoon,” reports CNBC:

“We’re investigating an issue in which users may be unable to access Outlook features and services,” Microsoft 365 Status, the official Microsoft account for 365 service incidents, said in a post on X…

The number of reports that services such as Microsoft Outlook, Microsoft Exchange, Microsoft Teams, Microsoft 365 and Microsoft Azure were down spiked after 3:30 p.m. ET. More than 37,000 individuals reported an Outlook outage and roughly 24,000 reported an outage in the tech company’s 365 service, according to Downdetector, while roughly 150 users reported their Teams accounts were down.
One hour ago Microsoft posted on X.com that “We’ve identified a potential cause of impact and have reverted the suspected code to alleviate impact. We’re monitoring telemetry to confirm recovery…”

Minutes later they added that “Our telemetry indicates that a majority of impacted services are recovering following our change. We’ll keep monitoring until impact has been resolved for all services.” And the official status page for Microsoft Office says “We’ve confirmed that reverting the impacting service update has returned the service to a healthy state. We’ve entered a period of extended monitoring to ensure that the service remains stable, and to address any outstanding impact to other Microsoft 365 services.”

Samsung’s midrange Galaxy A56 has AI photo editing and a bump for its buttons

While I naively hoped to see the Galaxy S25 Edge ahead of MWC, that wasn’t what I saw last week at Samsung’s pre-show briefing. However, what I did see might intrigue many of you: a cheaper slice of Galaxy hardware in the form of the Galaxy A56. It will be available later this year, starting at $499 (or £499 in the UK), which is slightly cheaper than the Pixel 8a when it first appeared. Samsung also announced the Galaxy A36 and A26 today, and they’ll start at $399 and $299 respectively. 

Many of the A series upgrades this year match what we saw from the S25. The A56 is thinner than its predecessor, down to 7.4mm from 8.2mm, while packing a marginally bigger 6.7-inch screen. The bezels, which were usually one of the most prominent visual tells of an A series, have been shaved the device’s bezels down further on the A56, too.

The hardware has been tweaked, with a brushed metal frame and a minor design twist: a new slightly protruding bump on the side where the volume and power buttons sit. When I got to handle the A56 briefly, I liked this. Asymmetry aside, it was easier to handle, which was surprising since this was a 6.7-inch device, and I’m more used to 6.3-inch phones. The A56 felt less unwieldy. (Did Samsung’s designers read my unhinged editorial on the sides of phones and decide to muddy the waters further? Perhaps.) 

It’s a mixed bag on camera specs this year. The front of the A56 now has a lower-res 12-megapixel selfie camera, while on the back sits an upgraded 12MP ultrawide, 50MP main sensor with an f/1.8 lens and optical image stabilization. There’s still a 5MP macro lens for someone out there. 

Those new cameras feature many of the latest upgrades on the S25 family, including improved image signal processing for better low-light performance, as well as a raft of AI features, including enhanced subject detection in portrait mode. Samsung says the A56 will better recognize sky, skin, faces, hair and grass for improved bokeh effects.

Regarding AI-powered image editing, there’s also Object Eraser, auto trim for videos and Create Filter, where you can choose an existing image and apply its color and tone to a different photo. You’ll also get Best Face, which lets you pick from multiple captures for everyone’s best expression, as long as you have motion photos enabled. These aren’t new features on smartphones, but their addition brings the midrange A56 closer to the Galaxy S25.

Through One UI 7, the A56 gets style flourishes and home screen improvements like the Now bar, notification panel changes and scalable widgets in different shapes and sizes. Samsung also promises six generations of OS updates (up from four on last year’s A55) and six years of security updates.

As you can tell by now, there aren’t any surprises here. The 5,000mAh battery is the same size as the A55’s, although the charging speed is now 45W. The company says you can charge the device fully in just over an hour. Samsung has swapped to its own 4nm Exynos 1580 chip, too, with CPU boosts of around 18 percent. The hardware, once again, inches closer to the quality and premium feel of what we typically see on Galaxy S devices.

It’s peak midrange phone season. The Galaxy A56 goes up against the recently launched iPhone 16e, while rumors suggest Google’s Pixel 9a could break cover very soon. 

Samsung also announced the Galaxy A36 5G and Galaxy A26 5G today, which both have 6.7-inch screens that get as bright as 1,200 nits and refresh at up to 120Hz. They come with One UI 7 as well, including features like Circle To Search that previously launched on pricier phones. Plus, they also feature triple camera systems on the rear with a 50MP main sensor, though their ultrawide setup camera is not as sharp as the A56 at 8MP. Some of the software features, like Best Face, are also reserved for the A56, though you’ll still find the updated Object Eraser and Filters on the pair of cheaper handsets. 

Finally, though the A36 and A26 have the same IP67 rating and 5,000mAh battery as the A56, they’ll only pack 6GB of RAM and the A36 uses the Snapdragon 6 Gen 3 processor instead of the Exynos 1580 in the A56. 

In the UK, the Galaxy A56 will go on preorder on March 2nd and launch on March 19th. It’ll come in four “awesome” (Samsung’s wording) colors, Graphite, Olive, Pink and Light Grey. Because nothing screams awesome like a lighter shade of grey. While we do have US pricing, Samsung hasn’t shared more precise timing for availability than “later this year.”
