Slashdot reader sciencehabit shared this report from Science magazine: Elephants love showering to cool off, and most do so by sucking water into their trunks and spitting it over their bodies. But an elderly pachyderm named Mary has perfected the technique by using a hose as a showerhead, much in the way humans do. The behavior is a remarkable example of sophisticated tool use in the animal kingdom. But the story doesn't end there. Mary's long, luxurious baths have drawn so much attention that an envious elephant at the Berlin Zoo has figured out how to shut the water off on her supersoaking rival—a type of sabotage rarely seen among animals. Both behaviors, reported today in Current Biology, further cement elephants as complex thinkers, says Lucy Bates, a behavioral ecologist at the University of Portsmouth not involved in the study. The work, she says, 'suggests problem solving or even 'insight.''

The Free Software Foundation turns forty on October 4, 2025 "and we will end our thirties on a high note!" they announced this week: We wish we were celebrating the achievement of software freedom for all computer users, but we're not there yet. Until our mission becomes reality and we can retire, instead, we are celebrating forty years of activism, and all that we have achieved. Since our founding in 1985, we laid out many stepping stones on the road to software freedom, and we're eager to continue building the road ahead. We will celebrate our fortieth in the spirit of bringing the international free software community together, discussing what we can do next to make the world freer, and celebrating how far we've come. We're aiming for a libre planet! Sounds familiar? Instead of hosting one LibrePlanet conference in 2025, we're planning a jam-packed anniversary year, filled with several new and exciting activities! We'll begin the anniversary year with an unprecedented memorabilia auction, starting as a silent auction on March 17, and culminating in a virtual live auction on March 23. By moving out of the FSF office, we got to sort through all the fun and historically important memorabilia and selected the best ones. This is your chance to get your very own personal souvenir of the FSF, from original GNU art to a famous katana and the very same VT220 that was standing on the FSF's front desk, and which people used to display ASCII art or to play free software games. Let's claim the month of May as libre planet (or libre local) month! We're inviting free software supporters like you anywhere in the world, to organize an in-person community meetup in your area to bring people together. We're setting up a small fund for these local gatherings, can send stickers, flyers, ideas and tips, and you can invite an FSF staff member to give a talk or workshop during your event and of course, we'll help promote it... Then, on the actual birthday of the FSF on October 4, 2025, there will be a big celebration in Boston, MA, and the entire free software community is invited... These are just some of the big ticket items we have worked out, but there is more! Keep an eye out on the FSF's pages, we'll be posting exact information on everything upcoming. They're looking for volunteers — and they also suggest organizing a community meetup in your area. Plus, there's also an FSF Anniversary Logo Contest. "We would like to source the fortieth anniversary logo design directly from a free software supporter. Everyone is welcome to submit a design (or even multiple designs) no matter your previous experience in design." The winning design "will be chosen by the community and ultimately immortalized in the history of the FSF," according to the announcement — displayed on the FSF homepage, printed on all celebration materials, "and possibly even stamped on some merchandise." But of course, the contest's requirements include respecting everyone's freedoms: - The logo must be produced using exclusively free software editing tools, such as GIMP, Krita, or Inkscape; - Any fonts used in the design must be under the SIL Open Font license or another free license... "The final logo will be released under CC BY, attributed to the FSF."

NASA hopes to stimulate in-space manufacturing through a multi-year "laser beam welding collaboration" with Ohio State University. The project "seeks to understand the physical processes of welding on the lunar surface," according to NASA.gov, "such as investigating the effects of laser beam welding in a combined vacuum and reduced gravity environment." The goal is to increase the capabilities of manufacturing in space to potentially assemble large structures or make repairs on the Moon, which will inform humanity's next giant leap of sending astronauts to Mars and beyond. "For a long time, we've used fasteners, rivets, or other mechanical means to keep structures that we assemble together in space," said Andrew O'Connor, a Marshall materials scientist who is helping coordinate the collaborative effort and is NASA's technical lead for the project. "But we're starting to realize that if we really want strong joints and if we want structures to stay together when assembled on the lunar surface, we may need in-space welding." The ability to weld structures in space would also eliminate the need to transport rivets and other materials, reducing payloads for space travel. That means learning how welds will perform in space. To turn the effort into reality, researchers are gathering data on welding under simulated space conditions, such as temperature and heat transfer in a vacuum; the size and shape of the molten area under a laser beam; how the weld cross-section looks after it solidifies; and how mechanical properties change for welds performed in environmental conditions mimicking the lunar surface. "Once you leave Earth, it becomes more difficult to test how the weld performs, so we are leveraging both experiments and computer modeling to predict welding in space while we're still on the ground," said O'Connor. In August 2024, a joint team from Ohio State's Welding Engineering and Multidisciplinary Capstone Programs and Marshall's Materials & Processes Laboratory performed high-powered fiber laser beam welding aboard a commercial aircraft that simulated reduced gravity. The aircraft performed parabolic flight maneuvers that began in level flight, pulled up to add 8,000 feet in altitude, and pushed over at the top of a parabolic arc, resulting in approximately 20 seconds of reduced gravity to the passengers and experiments. While floating in this weightless environment, team members performed laser welding experiments in a simulated environment similar to that of both low Earth orbit and lunar gravity. Analysis of data collected by a network of sensors during the tests will help researchers understand the effects of space environments on the welding process and welded material. They performed that laser-beam welding in a vacuum chamber during the parabolic flight (on a Boeing 727), according to the article — and successfully completed 69 out of 70 welds in microgravity and lunar gravity conditions. "The last time NASA performed welding in space was during the Skylab mission in 1973... "Practical welding and joining methods and allied processes, including additive manufacturing, will be required to develop the in-space economy."

Nathan Sobo "joined GitHub in late 2011 to build the Atom text editor," according to an online biography, "and he led the Atom team until 2018." Max Brunsfeld joined the Atom team in 2013, and "While driving Atom towards its 1.0 launch during the day, Max spent nights and weekends building Tree-sitter, a blazing-fast and expressive incremental parsing framework that currently powers all code analysis at GitHub." Last year they teamed up with Antonio Scandurra (another Atom alumnus) to launch a new startup called Zed (which in 2023 raised $10 million, according to TechCrunch). And today the open source blog It's FOSS checks in on their open-source code editor — "Zed Editor". Mainly written in Rust, it supports running in CLI, diagnosing project-wide errors, split panes, and markdown previews: By default, any added content is treated as plain text. I used the language switcher to change it to Rust so that I would get proper syntax highlighting, indentation, error detection, and other useful language-specific functions. The switch highlighted all the Rust elements correctly, and I then focused on Zed Editor's user interface. The overall feel of the editor was minimal, with all the important options being laid out nicely. [Its status bar] had some interesting panels. The first one I checked was the Terminal Panel, which, as the name suggests, lets you run commands, scripts, and facilitates interaction with system files or processes directly from within the editor. I then moved to the Assistant Panel, which is home to various large language models that can be integrated into Zed Editor. There are options like Anthropic, GitHub Copilot Chat, Ollama, OpenAI, and Google AI... The Zed Editor team has also recently introduced Zed AI in collaboration with Anthropic for assisting with coding, allowing for code generation, advanced context-powered interactions, and more... The real-time collaboration features on Zed Editor are quite appealing too. To check them out, I had to log in with my GitHub account. After logging in, the Collab Panel opened up, and I could see many channels from the official Zed community. I could chat with others, add collaborators to existing projects, join a call with the option to share my screen and track other collaborators' cursors, add new contacts, and carry out many other collaborative tasks. One can also use extensions and themes to extend what Zed Editor can do. There are some nice pre-installed themes as well.

"The Rust trademark policy has been updated and a new draft is available to view," announced the Rust Foundation this week. The last proposed trademark policy (in April of 2023) was criticized by open source advocate Bruce Perens in The Register as "far awry of fair use which is legally permitted." The Rust Foundation says this new version has "incorporated a number of suggestions from the Rust community," in a blog post that summarizes the feedback and enumerates specific ways it's been addressed: 1. We primarily plan to lean on community reports for enforcement and have no intention of spending our limited resources policing the work of small creators. 2. We have removed the non-legal language summary and instead have clarified wording throughout as best we can while keeping the policy valid. 3. The Rust trademark does not cover use of the word "Rust" in general and instead pertains to its use in relevant technical settings. 4. We have updated the logo usage policy. Color modifications are allowed. 5. The non-endorsement rule is about managing perception of official affiliation with the Foundation and Rust Project, and is thus subjective. 6. We removed restrictions on the use of "Rust" and "Cargo" in package names. The crates prefixes "rust-" and "cargo-" are no longer reserved to the Rust Project. 7. We will usually allow the community to use the marks on limited merchandise (more details in the updated draft).... [T]he central purpose of these updates is to empower all Rustaceans to engage with the Rust language ecosystem more confidently. As a final step in this process, we invite you to review the updated policy and share any blocking concerns you might have... Thank you to everyone who weighed in with helpful suggestions on the initial trademark policy draft we shared. The level of engagement and passion within the Rust community is inspiring to all of us at the Rust Foundation. The tech news site Heise Online writes "It is noticeable that the language is much clearer and dispenses with a lot of legal jargon," in a piece which argues the new draft "should calm the waves and create clarity." The new draft is not only formulated more simply, but is also significantly shorter. Some restrictions have been softened in the new rules or have disappeared completely... Meanwhile, the Foundation has also adapted its logo so that it is clear which logo stands for the programming language and which for the Foundation. The use of the name Rust is explicitly permitted to identify projects that are either written in the programming language or are compatible with it... Before the new trademark rules come into force, the Rust Foundation is collecting feedback on the current draft. The web form is open until November 20, 2024.

Sodium-ion batteries are cheaper than lithium-ion batteries — and they're also more environmentally friendly. And "In the past few years, sodium-ion battery production has increased in the United States," reports the Washington Post, with a new factory planned to manufacture them "in the same way as lithium-ion batteries, just with different ingredients. Instead of using expensive materials like lithium, nickel and cobalt, these will be made of sodium, iron and manganese..." Last month, sodium-ion battery manufacturer Natron Energy announced it would open a "gigafactory" in North Carolina that would produce 24 gigawatt hours of batteries annually, enough energy to charge 24,000 electric vehicles. But sodium-ion batteries are still early in their development compared with lithium-ion, and they have yet to hit the market on a massive scale. "It's unlikely sodium-ion could displace lithium-ion anytime soon," said Keith Beers, polymer science and materials chemistry principal engineer at technical consultancy firm Exponent... The biggest limitation of sodium-ion batteries is their weight. Sodium weighs nearly three times as much as lithium, and it cannot store the same amount of energy. As a result, sodium-ion batteries tend to be larger. Jens Peters, an economics professor at the University of Alcalá in Madrid, said the energy density could be improved over time in sodium-ion batteries. But, he added, "what we found out so far in our assessments is that it is not a game changer." Sodium-ion batteries are touted to be the environmentally friendly alternative to their lithium-ion counterparts, thanks to their raw materials. Sodium, iron and manganese are all abundant elements on the planet, so they require less energy to extract and cost less... Sodium-ion batteries also last longer than lithium-ion ones because they can withstand more charge cycles, said Wendell Brooks, co-CEO of Natron Energy. "Our product can have millions of cycles," said Brooks, "where lithium-ion would have three to five thousand cycles and wear out a lot faster...." Sodium-ion batteries aren't the best fit for smartphones or electric vehicles, which need to store lots of energy. However, one advantage is their low cost. And they could be a good candidate in situations where the size of the battery isn't a concern, like energy storage. "When something is built out to support grid or backup storage, it doesn't need to be very dense. It's staying put," Beers said. Natron will invest nearly $1.4 billion in the factory "to meet the rapidly expanding demand for critical power, industrial and grid energy storage solutions," according to their announcement. "Natron's high-performance sodium-ion batteries outperform lithium-ion batteries in power density and recharging speed, do not require lithium, cobalt, copper, or nickel, and are non-flammable... Natron's batteries are the only UL-listed sodium-ion batteries on the market today, and will be delivered to a wide range of customer end markets in the industrial power space, including data centers, mobility, EV fast charging, microgrids, and telecom, among others."

On Tuesday Massachusetts voted to become the first state to allow gig-working drivers to join labor unions, reports WBUR: Since these gig workers are classified as independent contractors, federal law allowing employees the right to unionize does not apply to them. With the passage of this ballot initiative, Massachusetts is the first state to give ride-hailing drivers the ability to collectively bargain over working conditions. Supporters have said the ballot measure "could provide a model for other states to let Uber and Lyft drivers unionize," reports Reuters, "and inspire efforts to organize them around the United States." Roxana Rivera, assistant to the president of 32BJ SEIU, an affiliate of the Service Employees International Union, that had spearheaded a campaign to pass the proposal, said its approval shows that Massachusetts voters want drivers to have a meaningful check against the growing power of app-based companies... The Massachusetts vote was the latest front in a years-long battle in the United States over whether ride-share drivers should be considered to be independent contractors or employees entitled to benefits and wage protections. Studies have shown that using contractors can cost companies as much as 30% less than employees. Drivers for Uber and Lyft, including approximately 70,000 in Massachusetts, do not have the right to organize under the National Labor Relations Act... Under the Massachusetts measure, drivers can form a union after collecting signatures from at least 25% of active drivers in Massachusetts, and companies can form associations to allow them to jointly negotiate with the union during state-supervised talks. But the Boston Globe points out that the measure " divided labor advocates in Massachusetts, some of whom worry it would in fact be a step backward in the lengthy fight to boost the rights of gig workers." Those concerns led the state's largest labor organization, the AFL-CIO, to remain neutral. But two unions backing the effort, the SEIU 32BJ and the International Association of Machinists, say allowing drivers to unionize, even if not as full employees, will help provide urgently needed worker protections and better pay and safety standards.

Friday "would have been his 38th birthday," writes the EFF, remembering Aaron Swartz as "a digital rights champion who believed deeply in keeping the internet open..." And they add that today the official web site for Aaron Swartz Day honored his memory with a special podcast "featuring those carrying on the work around issues close to his heart," including an appearance by Brewster Kahle, founder of the Internet Archive. The first speaker is Ryan Shapiro, FOIA expert and co-founder of the national security transparency non-profit Property of the People. The Aaron Swartz Day site calls him "the researcher who discovered why the FBI had such an interest in Aaron in the years right before the JSTOR fiasco." (That web page calls it an "Al Qaeda phishing expedition that left Aaron with an 'International Terrorism Investigation' code in his FBI database file forever," as reported by Gizmodo.) Other speakers on the podcast include: Nathan Dyer of SecureDrop, Newsroom Support Engineer for the Freedom of the Press Foundation with an update on SecureDrop Tracey Jaquith, Founding Coder and TV Architect at the Internet Archive, discussing "Microservices, Monoliths, and Operational Security — The Internet Archive in 2024." Tracy Rosenberg, co-founder of the Aaron Swartz Day Police Surveillance Project and Oakland Privacy, with "an update on the latest crop of surveillance battles." Ryan Sternlicht, VR developer, educator, researcher, advisor, and maker, on "The Next Layer of Reality: Social Identity and the New Creator Economy." Grant Smith Ellis, Chairperson of the Board, MassCann and Legal Intern at the Parabola Center, on "Jury Trials in the Age of Social Media." Michael "Mek" Karpeles, Open Library, Internet Archive, on "When it Rains at the Archive, Build an Ark — Book bans, Lawsuits, & Breaches." The site also seeks to showcase SecureDrop and Open Library, projects started by Aaron before his death, as well as new projects "directly inspired by Aaron and his work."

This week Discover magazine looks at evidence — both old and new — for a ninth planet in our solar system: "Orbits of the most distant small bodies — comets or asteroids — seem to be clustered on one half or one side of the solar system," says Amir Siraj [an astrophysicist with Princeton University]. "That's very weird and something that can't be explained by our current understanding of the solar system." A 2014 study in Nature first noted these orbits. A 2021 study in The Astronomical Journal examined the clustering in the orbit and concluded that "Planet Nine" was likely closer and brighter than expected. Astrophysicists don't agree whether the clustering in the orbit is a real effect. Some have argued it is biased because the view that scientists currently have is limited, Siraj says. "This debate for the last decade has a lot of scientists confused, including myself. I decided to look at the problem from scratch," he says. In a 2024 paper, Siraj and his co-authors ran simulations of the solar system, including an extra planet beyond Neptune. "We did it 300 times, about 2.5 times more than what was done previously," Siraj says. "In each simulation, you try different parameters for the extra planet. A different mass, a different tilt, a different shape of the orbit. You run these for millions of years, and then you compare the distribution to what we see in our solar system...." They found that the perimeters for this possible planet were different than what has been previously discussed in the scientific literature, and they supported the possibility of an unseen planet beyond Neptune. Scientists hope a new telescope will have the potential to see deeper into the solar system. In 2025, the Vera C. Rubin Observatory on Cerro Pachón — a mountain in Chile, is expected to go online. The observatory boasts that in the time it takes a person to open up their phone and pose for a selfie, their new telescope will be able to snap an image of 100,000 galaxies, many of which have never been seen by scientists. The telescope will have the largest digital camera ever built, the LSST. Siraj says he expects it will take "the deepest, all-sky survey that humanity has ever conducted." So, what might the Rubin Observatory find past Neptune? Based on the current literature, Siraj sees a few possibilities. One is that the Rubin Observatory, with its increased capabilities, might be able to see a planet beyond Neptune... "Next year is going to be an enormous year for solar system science," he says. NASA points out that the Hawaii-based Keck and Subaru telescopes are also searching for Planet X, while "a NASA-funded citizen science project called Backyard Worlds: Planet 9, encourages the public to help search using images captured by NASA's Wide-field Infrared Survey Explorer (WISE) mission. And starting next year the Rubin observatory will also "search for more Kuiper Belt objects. If the orbits of these objects are systematically aligned with each other, it may give more evidence for the existence of Planet X (Planet Nine), or at least help astronomers know where to search for it. "Another possibility is that Planet X (Planet Nine) does not exist at all. Some researchers suggest the unusual orbit of those Kuiper Belt objects can be explained by their random distribution." Thanks to long-time Slashdot reader Tablizer for sharing the news.
