El Nino Bursts Through Temperature Record Months Before Peak

The current El Nino has already surpassed the highest Pacific temperature anomaly recorded in the modern era, reaching 3.05C above the 1991-2020 average months before its expected peak. The commonly used ONI measure is also on the verge of breaking the 2015 record. Forecasts cited by The Guardian suggest the event could reach about 4.0C later this year. From the report: The latest data shows the temperature rise at the heart of El Nino in the Pacific Ocean has now reached 3.05C. That is higher than the 3.02C set in late November 2015, the previous high set in the 150 years of modern records. This temperature is measured against the average of 1991-2020. The preferred measure of most meteorologists uses a 30-year rolling average as a reference and so takes account of human-caused global heating. This metric, called ONI (Nino3.4), is on the brink of breaking the record, just one-hundredth of a degree below the 2015 record. Both metrics are underpinned by data from the US National Oceanic and Atmospheric Administration (NOAA). The most recent forecasts predict a peak of 4.0C in November and December, according to the average of 14 different models assessed by climate scientist Zeke Hausfather. That is a level so far above previous events that Hausfather called it "mind-blowing," while others have described it as "Godzilla-level." Any temperature rise above 0.5C is deemed an El Nino; above 2C is officially called a "very strong" El Nino -- often referred to as a "super" El Nino. The current El Nino is likely to be the largest in at least 1,000 years and will pile extra heat into an atmosphere in which temperatures are already rising rapidly due to human-caused global heating. This double whammy means 2027 is expected to "blow apart" previous records and become the hottest year ever recorded.

Microbes Could Survive On Saturn's Moon Enceladus

New research suggests Enceladus may be an especially promising place to search for extraterrestrial life: microbes similar to those found near Earth's hydrothermal vents survived in lab conditions designed to mimic the Saturnian moon's subsurface ocean. A separate study also found that material blasted from Enceladus' plumes may naturally separate and concentrate salts, organics and potential biosignatures into individual ice grains, potentially making them easier for future spacecraft to detect. "That is great news in the search for life," Frank Postberg, lead author of one and co-author of the other of these new studies and professor at Freie Universitat Berlin, said in a statement. "Future spacecraft will have to analyze many individual ice particles in the plume. But if they come across one with microbial material in it, they could identify biosignatures in the particle relatively easy with already available technology." Space.com reports: Enceladus isn't the only place in our solar system with water -- so, why is it so exciting in the search for life? Well, it has to do with the seafloor of its extensive, liquid ocean. Down deep at the bottom of this body of water, scientists think hydrothermal processes, or movement or reactions with hot water under the surface, are taking place. The plumes shooting upward from the ocean also contain trace amounts of salts and organic compounds. NASA's Cassini spacecraft found these traces when it flew through the plumes over a decade ago. Between the hydrothermal activity and the organics and minerals in the water, this moon's ocean has a number of aspects that could be involved in supporting life. What's more, using a combination of Cassini data, theoretical models and laboratory experimentation, in Postberg's new study the team found that the plume's water droplets blasting out into space at up to 621 miles per hour (1,000 kilometers per hour) don't freeze as quickly as expected. Before, scientists thought the freeze would happen instantaneously once the droplets reached space, but Postberg and fellow researchers say they found the freezing would actually happen much slower. They also found that during this freezing process, the salt, organic compounds (and maybe possible signs of life) in the water droplets separate from one another. Not only that, but the team says that as the particles are blasted out into space, they should often collide with the icy cracks of the planet's surface. This ultimately would leave behind tiny shards of frozen droplets with individually separated out components. Essentially, it's like the planet has organized its oceanic ingredients into tiny, frozen particle fragments. This work is described in two new studies published in the journal Science Advances here and here.

Bananas That Don't Go Brown To Hit Supermarkets Thanks to DNA Editing

An anonymous reader quotes a report from The Guardian: It is the bane of every fruit bowl: sliced banana that turns brown before it has reached the table. But such woes could soon be a thing of the past, with gene-edited bananas that keep their freshly peeled color now one step closer to reaching British shoppers. According to Tropic, the Norwich-based agricultural-biotechnology company that developed the fruit, the bananas have the same taste and texture but stay "fresh, yellow and appetizing long after peeling and slicing." Gilad Gershon, the chief executive of Tropic, said the flesh of the new banana resisted browning for an extra day or two -- and longer if chilled. He added that the innovation could make it easier to add bananas to prepackaged products such as fruit salads and breakfast pots, as well as reducing waste. [...] Tropic developed the bananas by using a gene-editing technology called Crispr-Cas9 to alter all three copies of a single gene within the fruit. As a result, they were able to reduce the production of polyphenol oxidase, an enzyme that causes browning. A similar approach has been effective in reducing browning in other produce, including mushrooms. Tropic said the non-browning bananas could reduce food waste and CO2-equivalent emissions along the supply chain by more than 25%. "This could support an annual reduction in CO2 emissions of over 9m tonnes in the banana export market alone," the company said. [...] Gershon said Tropic had gained regulatory approval for the non-browning bananas in 10 other countries including Japan, Brazil and the Philippines. The fruit is already being grown in Latin America.

MotifCentral: all things Motif/Xt/Xlib

Over the last few days and weeks or so, a few of the people I follow and interact with on Fedi have been talking about centralising information, tools, applications, and expertise from the Motif (and Xt, Xlib, and X11) ecosystem. There's a ton of information, resources, and actively maintained applications out there, but it's all spread out and sometimes difficult to find, and so Thomas Adam - one of the core developers of FVWM, among other things, as well as creator of CoW (FVWM for Wayland, more or less) - has created an effort to centralise all of this. Motif Central brings together information about Motif, Xt, Xlib and X11: how they fit together, how to program with them, and where to find the manuals, examples and historical material that explain them. Begin with the X programming stack, build your first Motif application, or explore the programming resources. The history pages describe the libraries' origins, while the archive guide helps you navigate older documentation. ↫ MotifCentral There's been a whole flurry of activity around Motif lately, including the updated and maintained fork we talked about a few weeks ago. The people loosely collaborating on MotifCentral also submitted patches to CDE to make sure it works on the new Motif fork, with the CDE developers setting up a build pipeline for easier testing. Making sure CDE, the classic Motif desktop environment, works well with the maintained Motif fork quite a few people seem to be rallying around is a worthwhile effort. We're still quite far from a complete(-ish) modern Motif ecosystem, but it's very heartwarming to see just how many people are actually still interested in it. My perhaps misguided hope is that we can somehow get to a modernised Motif/CDE desktop environment and applications, making it possible to more easily run a modern Motif environment on Linux and the BSDs. One may dream.

Windows 10 breaks far less often than Windows 11

Windows 11 received its September update on the 8th of this month, and within days Microsoft had acknowledged or investigated problems involving Remote Desktop, USB audio, Linux and WSL-based apps like Claude Cowork, and enterprise domain issues. Windows Latest also found File History failures, Explorer.exe crashes, and AMD GPU instability, with an emergency update following on September 14 that still did not fix everything. This got us curious, and we looked back across the nine monthly updates released from January through September 2026 and, rather unsurprisingly, Windows 10 update history isn't infected with nearly as many bugs as that of Windows 11. ↫ Abhijith M B at Windows Latest Of course, Windows 10 also isn't getting nearly as much attention from Microsoft, but that's kind of the whole point, isn't it? Whenever Microsoft touches something, especially over the last 5 years or so, it's one cascade of failures after the other, eroding trust in Windows' updates even more (if that's even possible). In that light, why would you want to use Windows 11 and all the headaches that come with it, when Windows 10 is right there, still being supported, albeit without the latest bells and whistles that only seem to break Windows 11 anyway? If you really do need or want to use Windows, consider switching back to Windows 10 whenever the usual Windows reinstallation time draws near. You won't lose much, but will gain quite a bit in the process. Of course, this won't be a responsible or usable choice forever, but at this point in time, I definitely think it's the optimal choice for quite a few people.

Amiga screens: a primer

One of the unwritten rules of the Internet seems to be that whenever something Amiga-related is mentioned, at least one Amiga fan (myself included) must show up and try to explain the concept of screens. Amiga screens can have different resolutions, we'll tell you, and one can drag them, we'll say, and other Amiga users rally in agreement, while non-Amiga users probably still don't get what's so great about screens. Until now, when this text has been written, in the hope of converting unsuspecting normies into full-blown Amiga screen lovers. ↫ Carl Svensson A deeply technical look at not just how the Amiga managed to achieve this stunning functionality way back in the '80s on machines with 7MHz and less RAM than a keyfob, but also how this functionality can be useful. I've always found the concept of screens on the Amiga quite interesting, and Svensson's article does a great job at demystifying the whole concept. Of course, expect a lot of lovely Amiga OS screenshots.

Resigning from Arch Linux

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.
