Ubuntu "is adopting the memory-safe Rust language," reports ZDNet, citing remarks at this year's Ubuntu Summit from Jon Seager, Canonical's VP of engineering for Ubuntu:

. Seager said the engineering team is focused on replacing key system components with Rust-based alternatives to enhance safety and resilience, starting with Ubuntu 25.10. He stressed that resilience and memory safety, not just performance, are the principal drivers: "It's the enhanced resilience and safety that is more easily achieved with Rust ports that are most attractive to me". This move is echoed in Ubuntu's adoption of sudo-rs, the Rust implementation of sudo, with fallback and opt-out mechanisms for users who want to use the old-school sudo command.

In addition to sudo-rs, Ubuntu 26.04 will use the Rust-based uutils/coreutils for Linux's default core utilities. This setup includes ls, cp, mv, and dozens of other basic Unix command-line tools. This Rust reimplementation aims for functional parity with GNU coreutils, with improved safety and maintainability.

On the desktop front, Ubuntu 26.04 will also bring seamless TPM-backed full disk encryption. If this approach reminds you of Windows BitLocker or MacOS FileVault, it should. That's the idea.

In other news, Canonical CEO Mark Shuttleworth said "I'm a believer in the potential of Linux to deliver a desktop that could have wider and universal appeal." (Although he also thinks "the open-source community needs to understand that building desktops for people who aren't engineers is different. We need to understand that the 'simple and just works' is also really important.")

Shuttleworth answered questions from Slashdot's readers in 2005 and 2012.

It's known as the "Dueling Dinosaurs" fossil: A triceratops and a tyrannosaur, skeletons entangled, locked in apparent combat right up until the moment of their mutual demise... That discovery in 2006 now appears to have overturned decades of dinosaur dogma about Tyrannosaurus rex, the fearsome giant long thought to be the sole top predator stalking the late Cretaceous. In a paper in the journal Nature, paleontologists Lindsay Zanno and James Napoli conclude that some of the bones from that specimen belong not to a teenage T. rex, but to a fully grown individual of a different tyrannosaur species — Nanotyrannus lancensis....

One of the first of those red flags in the new specimen was the arm bones. They looked completely different than T. rex's puny appendages... "These are powerful arms with large claws, large hands. They were using them for prey capture." Contrast that with T. rex, "an animal that's a mouth on legs." There were additional clues. The animal had fewer tail vertebrae and more teeth than T. rex. Zanno and Napoli considered other lines of evidence. They created 3D models of numerous purported T. rexes against which they compared their specimen. They looked at the growth stages of the cranial nerves and sinuses of close living relatives of dinosaurs, features that were visible in the fossilized skeleton.

"But maybe the most important and damning thing that we did was we were able to figure out that our animal is not a juvenile at all," she says. This conclusion was based on slicing through the fossil's limb bones to examine the growth rings. That work demonstrated that this animal was mature and done growing when it died around the age of 20. "That means it's half the size and a tenth of the mass of a full grown Tyrannosaurus rex," says Zanno... In addition, while making models of all those other alleged T. rex skeletons, Zanno says they identified another new species of tyrannosaur, one they're calling Nanotyrannus lethaeus...

"It tells us that these end-Cretaceous ecosystems right before the asteroid hit were flourishing," says Zanno. "They had an abundance of different predators. And refutes this idea that dinosaurs were in decline before the asteroid struck."

An anonymous reader shared this report from CNN:
[C]iting delays in Starship's development and competitive pressure from China, NASA asked SpaceX and Blue Origin — which holds a separate lunar lander contract with the space agency — to submit plans to expedite development of their respective spacecraft by October 29. Both companies have responded. But the space agency is also asking the broader commercial space industry to detail how they might get the job done more quickly, hinting that NASA leadership is prepared to sideline its current partners. CNN spoke with half a dozen companies about how they plan to respond to NASA's call to action, which the agency will formally issue once the government shutdown ends, according to a source familiar with the matter.

One possibility is Lockheed Martin...

Notably, as a legacy NASA contractor, the company built the $20.4 billion Orion spacecraft that astronauts will ride when they take off from Earth... Now, Lockheed says it can piece together a two-stage lunar lander that uses spare parts harvested from Orion. The company would make use of Space Shuttle-era OMS-E engines — which are also used on Orion — to serve as the propulsion for an "ascent stage" of the lunar lander, providing the thrust for the vehicle to lift off the moon after a mission is completed. But the vehicle also needs a descent stage to get down to the lunar surface in the first place...

Other commercial space companies contacted by CNN — including Firefly Aerospace and Northrop Grumman — said simply that they were "ready to support" NASA in its endeavor to find a faster way to complete the Artemis III mission. They did not confirm whether they would formally respond to the space agency's anticipated request for companies to submit proposals.

The more important goal, argue some experts, is to pave the way for a permanent lunar base where astronauts can live and work...

[P]erhaps the true winner will be the country that is able to build lasting infrastructure, experts say.
"It makes great press fodder to frame this as competition," said one space policy source, who was among several that spoke to CNN on the condition of anonymity to discuss controversial issues. "But this is about the long game and the sustainability."

Slashdot reader BrianFagioli writes: Password manager 1Password's 2025 Annual Report: The Access-Trust Gap exposes how everyday employees are becoming accidental hackers in the AI era. The company's data shows that 73% of workers are encouraged to use AI tools, yet more than a third admit they do not always follow corporate policies. Many employees are feeding sensitive information into large language models or using unapproved AI apps to get work done, creating what 1Password calls "Shadow AI." At the same time, traditional defenses like single sign-on (SSO) and mobile device management (MDM) are failing to keep pace, leaving gaps in visibility and control. The report warns that corporate security is being undermined from within. More than half of employees have installed software without IT approval, two-thirds still use weak passwords, and 38% have accessed accounts at previous employers. Despite rising enthusiasm for passkeys and passwordless authentication, 1Password says most organizations still depend on outdated systems that were never built for cloud-native, AI-driven work. The result is a growing "Access-Trust Gap" that could allow AI chaos and employee shortcuts to dismantle enterprise security from the inside.

"A nearby galaxy once thought to be dominated by dark matter seems to have a surprise supermassive black hole at its centre," reports New Scientist.

Yet scientists "are convinced dark matter is out there," writes Space.com. "The quest to detect it arguably remains both one of the most frustrating and most exhilarating challenges in modern physics."

And now they report that the century-old mystery of dark matter — the invisible glue thought to hold galaxies together — "just got a modern clue."

Scientists say they may be one step closer to confirming the existence of this elusive material, thanks to new simulations suggesting that a faint glow at the center of the Milky Way could be dark matter's long-sought signature. "It's very hard to actually prove, but it does seem likely," Moorits Muru of the Leibniz Institute for Astrophysics Potsdam in Germany, who led the new study, told Space.com...

The findings, show that dark matter near the Milky Way's center might not form a perfect sphere as scientists long thought. Instead, it appears flattened, almost egg-shaped, and that shape closely mirrors the pattern of mysterious gamma rays observed by NASA's Fermi Gamma-ray Space Telescope... Using powerful supercomputers, [the researchers] recreated how the Milky Way formed, including billions of years of violent collisions and mergers with smaller galaxies. Those violent events, the researchers found, left deep "fingerprints" on the way dark matter is distributed in the galactic core.... matching the pattern of gamma-ray emission Fermi has observed, the new study reports...

If the excess truly arises from dark matter collisions, it would mark the first indirect evidence that weakly interacting massive particles [WIMPs], a leading dark matter candidate, really exist...

"We have run dozens of direct detection experiments around the globe hunting for WIMPS," notes
Phys.org, in an article titled "The Empty Search for Dark Matter."

We have run dozens of direct detection experiments around the globe hunting for WIMPS — dark matter particles in this particular mass range. And they're not all the same kind of experiments. There are also the scintillators, which use a giant vat of liquefied noble gas, like several tons of xenon. They wait for a dark matter particle to strike the xenon and cause it to scintillate, which is a fancy science word for "sparkle." We see the sparkle; we detect dark matter...

They're just one example of a broader class of dark matter candidates, with delightful names like Q-balls, WIMPzillas, and sterile neutrinos. We've tuned our different experiments to capture different mass ranges or interaction strengths to cover as much of that wide dark matter spectrum as possible. We've even tried to manufacture various kinds of dark matter in our particle collider experiments.

And we've found nothing.

All-solid-state batteries (ASSBs) "are widely viewed as the 'holy grail' of EV battery tech," writes Electrek, "promising to double driving range, halve charging times, and reduce costs." Toyota hopes to launch its first production EV powered by the batteries in 2027 or 2028, and Mercedes-Benz and Volkswagen are also testing the technology.

But now Samsung SDI is teaming up with BMW and US-based battery company Solid Power for their own effort at commercializing all-solid-state EV batteries "in what's expected to be a trilateral powerhouse."

BMW and Solid Power have been working together to develop the next-gen battery tech since 2022...
Under the new agreement signed this week, Samsung will supply all-solid-state battery cells. Samsung will use Solid Power's Sulfide-Based Solid Electrolyte solution, while BMW will develop the battery pack and modules.

The strategic alliance aims to take the lead in commercializing all-solid-state batteries (ASSBs). Together, they've created a real-world system for producing ASSB cells, pooling their expertise in batteries, automaking, and materials to bring it closer to mass production. Solid Power's electrolyte solution is designed for stability and maximum conductivity. By teaming up with BMW and Samsung SDI, the company said it aims to bring all-solid-state batteries closer to widespread adoption.

"By pooling resources, BMW, Samsung SDI, and Solid Power have a real shot..." argues Electrek.

The Wall Street Journal looks at swarm robotics, where no single robot is in charge, robots interact only with nearby robots — and the swarm accomplishes complex tasks through simple interactions.

"Researchers say this approach could excel where traditional robots fail, like situations where central control is impractical or impossible due to distance, scale or communication barriers."

For instance, a swarm of drones might one day monitor vast areas to detect early-stage wildfires that current monitoring systems sometimes miss... A human operator might set parameters like where to search, but the drones would independently share information like which areas have been searched, adjust search patterns based on wind and other weather data from other drones in the swarm, and converge for more complete coverage of a particular area when one detects smoke.
In another potential application, a swarm of robots could make deliveries across wide areas more efficient by alerting each other to changing traffic conditions or redistributing packages among themselves if one breaks down. Robot swarms could also manage agricultural operations in places without reliable internet service. And disaster-response teams see potential for swarms in hurricane and tsunami zones where communication infrastructure has been destroyed.

At the microscopic scale, researchers are developing tiny robots that could work together to navigate the human body to deliver medication or clear blockages without surgery... In recent demonstrations, teams of tiny magnetic robots — each about the size of a grain of sand — cleared blockages in artificial blood vessels by forming chains to push through the obstructions. The robots navigate individually through blood vessels to reach a clog, guided by doctors or technicians using magnetic fields to steer them, says researcher J.J. Wie, a professor of organic and nano engineering at Hanyang University in South Korea. When they reach an obstruction, the robots coordinate with each other to team up and break through. Wie's group is developing versions of these robots that biodegrade after use, eliminating the need for surgical removal, and coatings that make the robots compatible with human tissue. And while robots the size of sand grains work for some applications, Wie says that they will need to be shrunk to nano scale to cross biological barriers, such as cell membranes, or bind to specific molecular targets, like surface proteins or receptors on cancer cells.

Some researchers are even exploring emergent intelligence — "when simple machines, following only a few local cues, begin to organize and act as if they share a mind...beyond human-designed
coordination."
