Scientists have discovered complex organic molecules within the icy plume erupting from Saturn's moon Enceladus, strengthening the case that its hidden saltwater ocean may harbor the conditions for life. The Guardian reports: The sixth largest of Saturn's moons, Enceladus has become one of the leading contenders in the search for bodies that could harbor extraterrestrial life, with the Cassini mission -- which ended in 2017 -- revealing the moon has a plume of water ice grains and vapors erupting from beneath the surface at its south pole. The phenomenon has since been captured by the James Webb space telescope, with the plume reaching nearly 6,000 miles into space. The source of this material is thought to be a saltwater ocean that lies beneath the moon's icy crust.
Now researchers studying data from the Cassini mission say they have discovered organic substances within the plume, with some types of molecule detected there for the first time. Dr Nozair Khawaja, a planetary scientist at Freie University Berlin and lead author of the work, said the results increased the known complexity of the chemistry that is happening below the surface of Enceladus. "When there is complexity happening, that means that the habitable potential of Enceladus is increasing right now," he said. Writing in the journal Nature Astronomy, Khawaja and colleagues reported how their previous work had revealed the presence of organic substances and salts within ice grains found in a ring of Saturn, known as the "E-ring," that is composed of material ejected from Enceladus. [...]
While the new findings do not show that there is life on Enceladus, Khawaja said they indicate there are complex chemical pathways at play that could lead to the formation of substances that could be biologically relevant. The results, he added, support plans by the European Space Agency (ESA) to investigate the moon for signs of life. "I think all the signals are green here for Enceladus," Khawaja said. The findings add momentum to ESA's proposed mission to directly search for biological signs around 2042. According to the ESA, the mission will consist of an orbiter around Enceladus that will also fly through the plumes, as well as a lander that will touch down in the south pole region of the moon.

The Apache Software Foundation has unveiled a major branding overhaul that retires its three-decade-old feather logo after criticism from Native American activists. In its place is a new oak leaf design to symbolize endurance, resilience, and global reach. Along with the new visual identity, the group will emphasize "The ASF" as its shorthand name while keeping its full legal title intact.
Apache.org explained: "The oak is one of the most enduring trees and is found around the world. It grows slowly but steadily, supporting vast ecosystems and lasting for centuries. In the same way, The ASF has served as a stable, resilient steward of open source for more than 25 years and is looking to the long future ahead. Choosing the oak leaf as our new logo represents the enduring power of our ethos: community over code."

Physicists have confirmed Stephen Hawking's 1971 black hole area theorem with near-absolute certainty, thanks to gravitational waves from an exceptionally loud black hole collision detected by upgraded LIGO instruments. New Scientist reports: Hawking proposed his black hole area theorem in 1971, which states that when two black holes merge, the resulting black hole's event horizon -- the boundary beyond which not even light can escape the clutches of a black hole -- cannot have an area smaller than the sum of the two original black holes. The theorem echoes the second law of thermodynamics, which states that the entropy, or disorder within an object, never decreases.
Black hole mergers warp the fabric of the universe, producing tiny fluctuations in space-time known as gravitational waves, which cross the universe at the speed of light. Five gravitational wave observatories on Earth hunt for waves 10,000 times smaller than the nucleus of an atom. They include the two US-based detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) plus the Virgo detector in Italy, KAGRA in Japan and GEO600 in Germany, operated by an international collaboration known as LIGO-Virgo-KAGRA (LVK).
The recent collision, named GW250114, was almost identical to the one that created the first gravitational waves ever observed in 2015. Both involved black holes with masses between 30 and 40 times the mass of our sun and took place about 1.3 billion light years away. This time, the upgraded LIGO detectors had three times the sensitivity they had in 2015, so they were able to capture waves emanating from the collision in unprecedented detail. This allowed researchers to verify Hawking's theorem by calculating that the area of the event horizon was indeed larger after the merger. The findings have been published in the journal Physical Review Letters.

Germany has already met its 2028 goal for reducing coal-fired power generation, so won't need to order the shutdown of any plants for a second year running, the country's regulator said. From a report: Germany has an interim 2028 target of reducing coal-fired power by 8.7 gigawatts, and as of Sept. 1 it had exceeded this level by about 10%, the Federal Network Agency said on its website on Monday.
Almost two thirds of Germany's electricity comes from renewables and excess solar power production has frequently pushed prices below zero, making burning coal less profitable. Yet Europe's largest economy remains heavily dependent on the fossil fuel and is still the European Union's biggest polluter.

FFmpeg 8.0 brings GPU-accelerated video encoding via Vulkan -- and can now subtitle your videos automatically using integrated speech recognition. From a report: At the start of the week, the FFmpeg project released its eighth major version. It's codenamed "Huffman" after the Huffman code algorithm, which was invented in 1952, making it one of the oldest lossless compression algorithms.
[...] The changelog lists 30 significant changes, of which the top new feature is integrating Whisper. This means whisper.cpp, which is Georgi Gerganov's entirely local and offline version of OpenAI's Whisper automatic speech recognition model. The bottom line is that FFmpeg can now automatically subtitle videos for you.

The Document Foundation, which operates the popular open source productivity suite LibreOffice, is positioning the suite's newest release, v25.8, as a strategic asset for digital sovereignty, targeting governments and enterprises seeking independence from foreign software vendors and cloud infrastructure.
The Document Foundation released the update last week with zero telemetry architecture, full offline capability, and OpenPGP encryption for documents, directly addressing national security concerns about extraterritorial surveillance and software backdoors. The suite requires no internet access for any features and maintains complete transparency through open source code that governments can audit. Government bodies in Germany, Denmark, and France, alongside national ministries in Italy and Brazil, have deployed LibreOffice to meet GDPR compliance, national procurement laws, and IT localization mandates while eliminating unpredictable licensing costs from proprietary vendors.
"It's time to own your documents, own your infrastructure, and own your future," the foundation wrote in a blog post.

Mark Tyson writes via Tom's Hardware: On this day 34 years ago, an unknown computer science student from Finland announced that a new free operating system project was "starting to get ready." Linus Benedict Torvalds elaborated by explaining that the OS was "just a hobby, [it] won't be big and professional like GNU." Of course, this was the first public outing for the colossal collaborative project that is now known as Linux. Above, you can see Torvalds' first posting regarding Linux to the comp.os.minix newsgroup. The now famously caustic, cantankerous, curmudgeon seemed relatively mild, meek, and malleable in this historic Linux milestone posting.
Torvalds asked the Minix community about their thoughts on a free new OS being prepared for Intel 386 and 486 clones. He explained that he'd been brewing the project since April (a few months prior), and asked for direction. Specifically, he sought input about other Minix users' likes and dislikes of that OS, in order to differentiate Linux. The now renowned developer then provided a rough summary of the development so far. Some features of Linux that Torvalds thought were important, or that he was particularly proud of, were then highlighted in the newsgroup posting. For example, the Linux chief mentioned his OS's multithreaded file system, and its absence of any Minix code. However, he humbly admitted the code as it stood was Intel x86 specific, and thus "is not portable."
Last but not least, Torvalds let it be known that version 0.01 of this free OS would be out in the coming month (September 1991). It was indeed released on September 17, 1991, but someone else decided on the OS name at the last minute. Apparently, Torvalds didn't want to release his new OS under the name of Linux, as it would be too egotistical, too self-aggrandizing. He preferred Freax, a portmanteau word formed from Free-and-X. However, one of Torvald's colleagues, who was the administrator for the project's FTP server, did not think that 'Freax' was an appealing name for the OS. So this co-worker went ahead and uploaded the OS as 'Linux' on that date in September, without asking Torvalds.

Last month, Python "reached the highest ranking a programming language ever had in the TIOBE index," according to TIOBE CEO Paul Jansen.
"We thought Python couldn't grow any further, but AI code assistants let Python take yet another step forward."
According to recent studies of Stanford University (Yegor Denisov-Blanch), AI code assistants such as Microsoft Copilot, Cursor or Google Gemini Code Assist are 20% more effective if used for popular programming languages. The reason for this is obvious: there is more code for these languages available to train the underlying models. This trend is visible in the TIOBE index as well, where we see a consolidation of languages at the top. Why would you start to learn a new obscure language for which no AI assistance is available? This is the modern way of saying that you don't want to learn a new language that is hardly documented and/or has too few libraries that can help you.
TIOBE's "Programming Community Index" attempts to calculate the popularity of languages using the number of skilled engineers, courses, and third-party vendors. It nows gives Python a 26.14% rating, which TechRepublic notes "is well ahead of the next two programming languages on this month's leaderboard: C++ is at 9.18% and C is 9.03%." But the first top six languages haven't changed since last year...
- Python
- C++
- C
- Java
- C#
- JavaScript
Since August of 2024 SQL has dropped from its #7 rank down to #12 (meaning Visual Basic and Go each rise up one rank from their position a year ago, into the #7 and #8 positions).
In the last year Perl has risen from the #25 position to #9, beating out Delphi/Oracle Pascal at #10, and Fortran at #11 (last year's #10). TIOBE CEO Jansen "told TechRepublic in an email that many people were asking why Perl was becoming more popular, but he didn't have a definitive answer. He said he double-checked the underlying data and found the increase to be accurate, though the reason for the shift remains unclear."

Jim Lovell, the legendary NASA astronaut who commanded the Apollo 13 "successful failure" mission, has died at age 97. From a report: Lovell was already well-known among NASA astronauts, having flown to space on the Gemini 7, Gemini 12 and Apollo 8 missions, before he was selected to command Apollo 13, which would have marked the third successful crewed moon landing for NASA. But during the ill-fated mission -- which carried Lovell as well as astronauts John Swigert Jr. and Fred Haise Jr. on board -- an oxygen tank located on the crew's service module exploded when they were about 200,000 miles (322,000 kilometers) away from Earth.
Lovell delivered the news to mission control, saying "Houston, we've had a problem." With the damage effectively taking out the crew's power source and other life support supplies, the Apollo 13 crew had to abruptly abandon their trek to the lunar surface and use several engine burns to swing around the far side of the moon and put themselves on a course back toward Earth. The three-person crew made a high-stakes splashdown return in the South Pacific Ocean about three days after the tank explosion, marking the conclusion of what has come to be known as the "successful failure" of the Apollo missions. The ordeal was fictionalized in Ron Howard's 1995 film "Apollo 13." [...]
Lovell was the first astronaut to make four spaceflights, totaling more than 715 hours in space. He was part of NASA's second-ever astronaut class, selected in September 1962 and nicknamed the "New Nine." And joining the Apollo 13 crew after having first served on Apollo 8, which intentionally circumnavigated the moon but did not land on its surface, made Lovell the first human ever to see the moon up close for a second time.
