"Scientists have discovered a virus that is a tiny bit human, carrying a gene it stole from our ancestors about 100,000 years ago," writes the New York Times. "And this virus may be using our own gene to infect us." Phys.org explains that it's "both an important gene for brain function and a jumping gene capable of moving and inserting itself into genomes." BC200 is found only in humans and related primates and was discovered in the late 1980s as an abundant noncoding RNA in human neurons. Although BC200's physiological function is poorly understood, evidence suggests it may be involved in regulating the translation of neuronal messenger RNAs into proteins... The researchers also suspect that BC200 jumped in skin cells because these are the only cells known to be infected by molluscum contagiosum virus (MCV). The gene is also abnormally expressed in some tumors and overexpressed in the brains of patients with Alzheimer's disease, suggesting its jumping ability could play roles in these diseases. [Cedric Feschotte, a senior author of the study] said he and his colleagues would like to explore whether the molluscum contagiosum virus uses BC200 to manipulate human host cells. They are also interested in better understanding the gene's role in disease, including breast and other types of tumors in which it is abnormally expressed, and whether it jumps in cancer cells and causes mutations.

While most magnets have two poles (north and south, or positive and negative), recent advances in quantum mechanics have revealed an "octupolar order," writes Phys.org, where a pattern of particles in a crystalline structure "behaves as if it has eight magnetic poles rather than the familiar two." Now, a team led by quantum physicists at the University of Toronto has established a new method for observing quantum magnetic states using light to probe the atomic vibrations produced as electrons spin. The work is a critical first step toward harnessing multipolar magnetism for practical technologies, including next-generation data storage and computing devices. "We identified new signatures of a hidden type of magnetic state which cannot be detected using ordinary probes," says Arun Paramekanti, a professor in the Department of Physics and the Center for Quantum Information & Quantum Control in the Faculty of Arts & Science at the University of Toronto, and senior author of a study published in Physical Review Letters that describes the findings. "Our research opens up the possibility for using higher-order magnets in several applications including controllable read-write memory elements found in everyday computers...." By directing a special type of rotating light at magnetic materials, the team observed a clear optical fingerprint of the otherwise hidden magnetic order.... The findings offer a new tool for uncovering and manipulating previously inaccessible forms of magnetism, opening new avenues for quantum technology development.

404 Media reports: "We will not add facial recognition to our devices," Flock CEO Garrett Langley said in a recent video. But other, third-party companies are telling cops that they are willing to add facial recognition to data gathered by Flock cameras in order to "close that gap." A company called VIDIZMO is advertising the capability to export footage from FlockOS to its own platforms that do facial recognition, behavior prediction, and racial and gender analysis on live camera feeds. VIDIZMO is a several decades-old video analysis and database company that has started offering facial recognition technology to cops within the last six months. In a May email to Johnson City, Tennessee, deputy police chief Michael Adams, a salesperson from VIDIZMO wrote that the company's product could do facial recognition on both Flock and Axon [body-worn camera] data in "one searchable platform...." VIDIZMO's CEO, Nadeem Khan, told 404 Media on a video call that the company has not yet started running facial recognition tech on footage from Flock cameras, and that it has not actually built the specific tool that would export data from Flock's system to its own platform (though the company advertises this capability online, and the company already sells other facial recognition products). But Khan said VIDIZMO "would love to do the integration," and that he believes facial recognition "is the way the world is going, the way the world will have to be," and that he thinks Flock should offer the capability itself in a way that "balances privacy, security, and the freedom that we enjoy in this country." The article notes that VIDIZMO says on its website, "You can identify individuals from seven races: White, Black, Indian, East Asian, Southeast Asian, Middle Eastern, and Latino Hispanic." VIDIZMO adds that stores or cities can also then do "demographic analysis" for marketing purposes by determining the races or ages of people showing up....

Google launched its Googlebooks platform a week ago, and a lot of people were wondering what this meant for Chrome OS and Chromebooks. Since Googlebooks and its Android-based Googlebook OS lack the management frameworks markets like schools require, Chromebooks will continue to be available for now, until such time Googlebooks catch up in that regard. However, in a support document, Google states that update support for all Chromebook devices will end in 2034: ChromeOS devices will continue to receive regular updates and security patches through mid-2034. For qualifying devices purchased today whose 10-year support lifecycle extends beyond 2034, Google is committed to supporting your transition to Googlebook OS, with many devices offering direct migration paths. ↫ Google support document Google promised 10 years of updates for all Chromebooks, and it's now breaking that promise for anyone buying a Chromebook between now and whenever the last Chromebook rolls off the production line. Sadly, we live in a world where corporations are free to make and break whatever promises they want virtually free of consequences, and as society we're so used to it that anti-consumer behaviour like this barely elicits a shrug. Google does state that "many newer commercial Chromebook models will be capable of upgrading to Googlebook OS", but that, too, is just another promise - and a vague, one at that - so who knows how many devices will actually be capable of upgrading out in the real world. On top of that, we have no idea if Googlebooks will just be yet another in a long line of quickly abandoned Google tablet/laptop projects, further adding to the uncertainty. Stuff like this should not be legal.

In June 2008 Apple announced Mac OS X Snow Leopard, proudly boasting that it would have "no new features". Instead of piling on new things, Snow Leopard aimed to build on the success of its predecessor, Leopard, opting to focus on under-the-hood performance and stability improvements throughout the system. 18 years later, Apple is taking a similar approach with macOS 27. Golden Gate aims to fix the missteps of last year's Tahoe, promising an expansive set of improvements and "a more responsive and delightful experience". Does it hold up? Here are just some of the bugs I've encountered in my daily use over the past couple of weeks. ↫ Chester at SquareOrbits I'm getting some real Windows 11 vibes from this long list of bugs and issues, further underlining my perception that Apple completely lost the plot when it comes to Mac OS X (in the past) and MacOS (today). These are not the kind of things you'd find in the heydays of Mac OS X, back when I was a devout user, and makes me glad I abandoned ship long, long ago (around the time of the Intel transition). I don't see stuff like this in GNOME or KDE, and while not nearly as bad as Windows 11, the cracks are obvious. I am by no means an expert at how Apple is run and how it organises itself, but as a layperson I do wonder if the company is simply trying to do too much - too many different platforms, too many different crucial components it all develops internally, too many different markets to please. Things are going to fall through the cracks when you try to keep this many plates spinning.

Over the last few weeks, we have been doing research on the integration of our official distribution packages when installed on a target system. In this context we have been looking at the current uses of alpm-install-scriptlet(5) files and alpm-hooks(5) in around 120 package source repositories (alpm-source-repo(7)) to better understand the underlying functionality and use-cases these two integrations offer and target. In this article we are going to look at how these two systems work, how Arch Linux is currently using them and attempt to provide suggestions for when to use which.

This is just a short note on my blog that I have resigned from Arch Linux a package maintainer, developer and security team. I've spent around 10 years as an AUR maintainer, security team, Package Maintainer and then Developer. I implemented support for debug packages, did the initial POC work that would become the git migration and even somehow managed to pull of an online conference during The Plague with the help of others.
