Forty years ago, the catastrophic explosion at Chernobyl sent plumes of radioactive waste into the atmosphere. Now, New Scientist has gained exclusive access to learn how vital work to decontaminate the site has been derailed by Russia’s full-scale invasion of Ukraine

New Scientist reporter Matthew Sparkes secured unrivalled access to Chernobyl's most crucial scientific sites, where researchers are fighting to protect the area and ensure it remains safe amid the constant threat of attack from Russia

Ever heard of a condition called bixonimania? Did you search the internet or ask your “AI” girlfriend about some symptoms you were experiencing, and this was its answer? Well… The condition doesn’t appear in the standard medical literature — because it doesn’t exist.

Version 7.0 of the Linux kernel has been released, marking the arbitrary end of the 6.x series. Significant changes in this release include the removal of the “experimental” status for Rust code, a new filtering mechanism for io_uring operations, a switch to lazy preemption by default in the CPU scheduler, support for time-slice extension, the nullfs filesystem, self-healing support for the XFS filesystem, a number of improvements to the swap subsystem (described in this article and this one), general support for AccECN congestion notification, and more.

The astronauts of the Artemis II mission around the moon have made it home safely to Earth, marking the end of a triumphant mission and the beginning of a longer road to stay on the moon

It shouldn’t be a surprise that companies – and for our field, technology companies specifically – working with the defense industry tends to raise eyebrows. With things like the genocide in Gaza, the threats of genocide and war crimes against Iran, the mass murder in Lebanon, it’s no surprise that western companies working with the militaries and defense companies involved in these atrocities are receiving some serious backlash.

Some cats will suddenly refuse to touch brands of cat food that they have eaten for years. Changing the way the food smells might solve the problem

A handful of plankton fossils buried in a small chunk of rock show that the oceans were teeming with life before the Late Ordovician mass extinction, the second most severe on record

If you want to run FreeBSD on a laptop, you’re often yanked back to the Linux world of 20 years ago, with many components and parts not working and other issues such as sleep and wake problems. FreeBSD has been hard at work improving the experience of using FreeBSD on laptops, and now this has resulted in a list of laptops which work effortlessly with the venerable operating system.

It may sound unbelievable to some, but not everyone has a datacenter beast with 128GB of VRAM shoved in their desktop PCs. Around the world people tell the tale of a particularly fierce group of Linux gamers: Those who dare attempt to play games with only 8 gigabytes of VRAM, or even less.

Physicists have shown how time can effectively be reversed for some quantum systems, which would allow for new ways to harvest energy

The incompleteness theorem is accepted as part of the mathematical canon today, but columnist Jacob Aron says it was a bombshell when Kurt Gödel first introduced it. Gödel’s seminal work directly contradicted one of the great minds of mathematics and limited the field forever

Two extremely precise experiments agree with a previously shocking measurement of just how big the proton is, which may help future searches for new particles

You might have seen this, one of the strangest and most primitive experiences in macOS, where you’re asked to press keys next to left Shift and right Shift, whatever they might be. Perhaps I can explain.

This post aims to be a high level introduction to using USB for people who may not have worked with Hardware too much yet and just want to use the technology. There are amazing resources out there such as USB in a NutShell that go into a lot of detail about how USB precisely works (check them out if you want more information), they are however not really approachable for somebody who has never worked with USB before and doesn’t have a certain background in Hardware.

The months keep coming, and thus, the monthly progress reports keep coming, too, for Redox, the new general purpose operating system written in Rust. This past month, there’s been considerable graphics improvements, better deadlock detection in the kernel, improved Unicode support thanks to switching over to ncurses library variant with Unicode support, and much more.

From 2024, but still accurate and interesting: Plan 9 is unique in this sense that everything the system needs is covered by the base install. This includes the compilers, graphical environment, window manager, text editors, ssh client, torrent client, web server, and the list goes on.

Anos is a modern, opinionated, non-POSIX operating system (just a hobby, won’t be big and professional like GNU-Linux) for x86_64 PCs and RISC-V machines. Anos currently comprises the STAGE3 microkernel, SYSTEM user-mode supervisor, and a base set of servers implementing the base of the operating system.

This year sees 35 years since 2.11BSD was announced on March 14, 1991 – itself a slightly late celebration of 20 years of the PDP-11 – and January 2026 brought what looks to be the venerable 16-bit OS’s biggest ever patch! Much of the 1.3 MB size is due to Anders Magnusson, well-known for his work on NetBSD and the Portable C Compiler.

Four NASA astronauts have now travelled further from Earth than any humans before them, as they flew around the moon during the Artemis II mission on 6 April

Anyone remember the KDE 4.0 themes Oxygen and Air? Well, several KDE developers have been working tirelessly to bring them back, which means they’re patching it up, fixing bugs, and generally making these classic themes work well in the current releases of KDE Plasma 6.

This is a great post, but obviously it hasn’t convinced me: The folks waving their arms and yelling about recent models’ capabilities have a point: the thing works. This project finished in three weeks.

Iodine deficiency is on the rise among people in the UK, the US and Australia. A century ago this led to drops in IQ, height and thyroid health – and the modern fancy salt fad may be leading to a resurgence, says columnist Alice Klein

Cornish sea salt crystals, pink Himalayan rock salt, smoked salt flakes – the use of gourmet salts is on the rise. But columnist Alice Klein finds it may be leading to a resurgence in iodine deficiency, with harmful consequences

Another major improvement in Redox: a brand new scheduler which improves performance under load considerably. We have replaced the legacy Round Robin scheduler with a Deficit Weighted Round Robin scheduler.

You’d think if there was one corner of the open source world where you wouldn’t find drama it’d be open source office suites, but it turns out we could not have been more wrong. First, there’s The Document Foundation, stewards of LibreOffice, ejecting a ton of LibreOffice contributors.

This is the first of a series of articles in which you will learn about what may be one of the silliest, most preventable, and most costly mishaps of the 21st century, where Microsoft all but lost OpenAI, its largest customer, and the trust of the US government.

I assume I don’t have to explain the difference between big-endian and little-endian systems to the average OSNews reader, and while most systems are either dual-endian or (most likely) little-endian, it’s still good practice to make sure your code works on both.

An incredibly powerful flash of X-rays spotted by the Einstein Probe telescope appears to be a kind of explosion first theorised more than 30 years ago

Recognising rhythmic patterns was thought to require a big brain, but a series of experiments has shown that buff-tailed bumblebees have this ability, too

Nelson Dellis credits techniques like the method of loci for his extraordinary memory. Now, brain scans have revealed the parts of his brain that this approach taps into, and how we can use it to improve our own recall

A galaxy spotted by the James Webb Space Telescope, known as Hebe, that existed just 400 million years after the big bang appears to contain extremely pure and young stars

If you are unlucky enough to have been bitten by a snake, you are unlikely to want to repeat the experience. Not so for Tim Friede, who intentionally exposes himself to deadly bites in the hope of developing a treatment for the 5 million people who are bitten each year

I don’t like to cover “current events” very much, but the American government just revealed a truly bewildering policy effectively banning import of new consumer router models. This is ridiculous for many reasons, but if this does indeed come to pass it may be beneficial to learn how to “homebrew” a router.

Why do so many people keep falling for the same trick over and over again? With an over $400 billion gap between the money invested in AI data centers and the actual revenue these products generate, Silicon Valley slowly returned to the tested and trusted playbook: advertising.

By reimplementing these features using capabilities, we made the kernel simpler by moving complex scheme and namespace management out of it which improved security and stability by reducing the attack surface and possible bugs.

Of course, it was only a matter of time before the time-honoured tradition of the demoscene also got infected by “AI”. For me personally, generative AI ruins much of the fun. I still enjoy creating pixel art and making little animations and demos.

Even if the conflict in the Middle East ends today, higher fuel, fertiliser and pesticide prices will lead to a food shock in the coming months. There is no easy way out, but accelerating the net-zero transition will help prevent future shocks

Cognitive decline, mental health and heart disease are all shaped by the deep links between heart and brain – with major implications for diagnoses and treatment

Researchers have identified genetic material from a vast range of organisms contaminating the shroud, said to have wrapped Jesus's body, further complicating the question of the cloth's true origin
