NASA's Curiosity rover has identified a diverse set of organic molecules on Mars, including a nitrogen-bearing compound similar in structure to DNA precursors. The finding strengthens the case that ancient organic material can survive in the Martian subsurface, though it does not prove past life because the compounds could also come from geology or meteorites. Phys.org reports: The study was led by Amy Williams, Ph.D., a professor of geological sciences at the University of Florida and a scientist on the Curiosity and Perseverance Mars rover missions. Curiosity landed on Mars in 2012 to find evidence that ancient Mars had conditions that could support microbial life billions of years ago; the Perseverance rover, which landed in 2021, was sent to look for signs of any ancient life that might have formed.

Among the 20-plus chemicals identified by the experiment, Curiosity spotted a nitrogen-bearing molecule with a structure similar to DNA precursors -- a chemical never before spotted on Mars. The rover also identified benzothiophene, a large, double-ringed, sulfurous chemical often delivered to planets by meteorites. "The same stuff that rained down on Mars from meteorites is what rained down on Earth, and it probably provided the building blocks for life as we know it on our planet," Williams said. The findings have been published in the journal Nature Communications.

BrianFagioli shares a report from NERDS.xyz: An international team of scientists has done something chemistry has never seen before. IBM, working alongside researchers from the University of Manchester, Oxford University, ETH Zurich, EPFL, and the University of Regensburg, has created and characterized a molecule whose electrons travel through its structure in a corkscrew-like pattern, fundamentally altering its chemical behavior. The findings were published today in Science. The molecule, known as C13Cl2, is the first experimental observation of what scientists call a half-Mobius electronic topology in a single molecule. To the researchers' knowledge, nothing like it has ever been synthesized, observed, or even formally predicted. And proving why it behaves the way it does required something equally extraordinary -- a quantum computer.

The whole thing started at IBM, where the molecule was assembled atom by atom from a custom precursor synthesized at Oxford. Working under ultra-high vacuum at near-absolute-zero temperatures, researchers used precisely calibrated voltage pulses to remove individual atoms one at a time. The result is an electronic structure that undergoes a 90-degree twist with each circuit through the molecule, requiring four complete loops to return to its starting phase. That is a topological property that has no counterpart anywhere in chemistry's existing record. What makes it even more interesting to folks who follow materials science is that this topology can be switched. The molecule can move reversibly between clockwise-twisted, counterclockwise-twisted, and untwisted states. That means electronic topology is not just a curiosity to be stumbled upon in nature -- it can be deliberately engineered. That is a big deal.

The quantum computing angle here is not just a supporting role. Electrons within C13Cl2 interact in deeply entangled ways, each influencing the others simultaneously. Modeling that requires tracking every possible configuration of those interactions at once -- something that causes computational demands to grow exponentially and can quickly overwhelm classical machines. A decade ago, researchers could exactly model 16 electrons classically. Today that number has crept to 18. Using IBM's quantum computer, the team was able to explore 32 electrons. Quantum computers can represent these systems directly rather than approximate them, because they operate according to the same quantum mechanical laws that govern electrons in molecules. In this case, that capability helped reveal helical molecular orbitals for electron attachment -- a fingerprint of the half-Mobius topology -- and exposed the mechanism behind the unusual structure: a helical pseudo-Jahn-Teller effect.

With NASA's Mars Sample Return mission delayed into the 2030s, engineers are certifying the Perseverance rover to keep operating for many more years while it continues collecting and safeguarding Martian rock samples. Ars Technica reports: The good news is that the robot, about the size of a small SUV, is in excellent health, according to Steve Lee, Perseverance's deputy project manager at NASA's Jet Propulsion Laboratory (JPL). "Perseverance is approaching five years of exploration on Mars," Lee said in a press briefing Wednesday at the American Geophysical Union's annual fall meeting. "Perseverance is really in excellent shape. All the systems onboard are operational and performing very, very well. All the redundant systems onboard are available still, and the rover is capable of supporting this mission for many, many years to come."

The rover's operators at JPL are counting on sustaining Perseverance's good health. The rover's six wheels have carried it a distance of about 25 miles, or 40 kilometers, since landing inside the 28-mile-wide (45-kilometer) Jezero Crater in February 2021. That is double the original certification for the rover's mobility system and farther than any vehicle has traveled on the surface of another world. Now, engineers are asking Perseverance to perform well beyond expectations. An evaluation of the rover's health concluded it can operate until at least 2031. The rover uses a radioactive plutonium power source, so it's not in danger of running out of electricity or fuel any time soon. The Curiosity rover, which uses a similar design, has surpassed 13 years of operations on Mars.

There are two systems that are most likely to limit the rover's useful lifetime. One is the robotic arm, which is necessary to collect samples, and the other is the rover's six wheels and the drive train that powers them. "To make sure we can continue operations and continue driving for a long, long way, up to 100 kilometers (62 miles), we are doing some additional testing," Lee said. "We've successfully completed a rotary actuator life test that has now certified the rotary system to 100 kilometers for driving, and we have similar testing going on for the brakes. That is going well, and we should finish those early part of next year."

An anonymous reader shared this report from the Los Angeles Times: Popular podcast host Steven Bartlett has used an AI clone to launch a new kind of content aimed at the 13 million followers of his podcast "Diary of a CEO." On YouTube, his clone narrates "100 CEOs With Steven Bartlett," which adds AI-generated animation to Bartlett's cloned voice to tell the life stories of entrepreneurs such as Steve Jobs and Richard Branson. Erica Mandy, the Redondo Beach-based host of the daily news podcast called "The Newsworthy," let an AI voice fill in for her earlier this year after she lost her voice from laryngitis and her backup host bailed out...

In podcasting, many listeners feel strong bonds to hosts they listen to regularly. The slow encroachment of AI voices for one-off episodes, canned ad reads, sentence replacement in postproduction or translation into multiple languages has sparked anger as well as curiosity from both creators and consumers of the content. Augmenting or replacing host reads with AI is perceived by many as a breach of trust and as trivializing the human connection listeners have with hosts, said Megan Lazovick, vice president of Edison Research, a podcast research company... Still, platforms such as YouTube and Spotify have introduced features for creators to clone their voice and translate their content into multiple languages to increase reach and revenue. A new generation of voice cloning companies, many with operations in California, offers better emotion, tone, pacing and overall voice quality...

Some are using the tech to carpet-bomb the market with content. Los Angeles podcasting studio Inception Point AI has produced its 200,000 podcast episodes, in some weeks accounting for 1% of all podcasts published that week on the internet, according to CEO Jeanine Wright. The podcasts are so cheap to make that they can focus on tiny topics, like local weather, small sports teams, gardening and other niche subjects. Instead of a studio searching for a specific "hit" podcast idea, it takes just $1 to produce an episode so that they can be profitable with just 25 people listening... One of its popular synthetic hosts is Vivian Steele, an AI celebrity gossip columnist with a sassy voice and a sharp tongue... Inception Point has built a roster of more than 100 AI personalities whose characteristics, voices and likenesses are crafted for podcast audiences. Its AI hosts include Clare Delish, a cooking guidance expert, and garden enthusiastNigel Thistledown...

Across Apple and Spotify, Inception Point podcasts have now garnered 400,000 subscribers.

NASA has lost contact with its MAVEN Mars orbiter after it passed behind Mars. When it remerged from behind the planet, the spacecraft never resumed communications. SpaceNews reports: MAVEN launched in November 2013 and entered orbit around Mars in September 2014. The spacecraft's primary science mission is to study the planet's upper atmosphere and interactions with the solar wind, including how the atmosphere escapes into space. That is intended to help scientists understand how the planet changes from early in its history, when it had a much thicker atmosphere and was warm enough to support liquid water on its surface.

MAVEN additionally serves as a communications relay, using a UHF antenna to link the Curiosity and Perseverance rovers on the Martian surface with the Deep Space Network. NASA's Mars Odyssey and Mars Reconnaissance Orbiter spacecraft also serve as communications relays for the rovers, but are both significantly older than MAVEN. The spacecraft has suffered some technical problems in the past, notably with its inertial measurement units (IMUs) used for navigation. In 2022, MAVEN switched to an "all-stellar" navigation system to minimize the use of the IMUs.

MAVEN has enough propellant to maintain its orbit through at least the end of the decade. NASA's fiscal year 2026 budget proposal, though, zeroed out funding for MAVEN, which cost $22.6 million to operate in 2024. MAVEN was one of several missions "operating well past the end of prime mission" the proposal would terminate, despite MAVEN's role as a communications relay.

Curiosity Stream, the decade-old science documentary streaming service founded by Discovery Channel's John Hendricks, expects its AI licensing business to generate more revenue than its 23 million subscribers by 2027 -- possibly earlier. The company's Q3 2025 earnings revealed a 41% year-over-year revenue increase, driven largely by deals licensing its content to train large language models. Year-to-date AI licensing brought in $23.4 million through September, already exceeding half of what the subscription business generated for all of 2024.

The streaming service's library contains 2 million hours of content, but the "overwhelming majority" is earmarked for AI licensing rather than subscriber viewing, CEO Clint Stinchcomb said during the earnings call. Curiosity Stream is licensing 300,000 hours of its own programming and 1.7 million hours of third-party content to hyperscalers and AI developers. The company has completed 18 AI-related deals across video, audio, and code assets.

An anonymous reader quotes a report from the Washington Post: Winning the lottery isn't what brought Carrie Edwards her 15 minutes of fame. It was giving it all away. Standing alone in her kitchen one day in September, the Virginia woman was thunderstruck to discover she had won $150,000 in a Powerball drawing. As she was absorbing her windfall, she said, "I just heard as loud as you can hear God or whoever you believe in the universe just say, this is -- it's not your money." Then came a decision: She would donate it all to her three most cherished charities (source paywalled; alternative source). [...] Her journey to the lucky prize started when she walked into a 7-Eleven with a friend who wanted to buy two Powerball tickets. The jackpot for the Sept. 6 drawing was topping $1.7 billion, the second-largest amount ever. Edwards, 68, hardly ever played the lottery, but her friend was an active player who gave her two pieces of advice: Always buy a paper ticket, rather than getting them online. And the Powerball multiplier is a scam, don't do it. She ignored him on both accounts.

She created a Virginia Lottery account on her phone. Then, instead of the typical strategies of using family birthdays and lucky numbers, she went to ChatGPT -- which she had only recently started using for research -- and asked, "Do you have any winning numbers for me?" "Luck is luck," replied the chatbot. Then it gave numbers that she plugged in -- paying the extra dollar for the Power Play to multiply anything she might win. She initially thought luck wasn't on her side when she didn't win the massive jackpot. But what she didn't realize is that she'd picked the "draw two" option, meaning her numbers were reentered for the next drawing. When she got a notification on her phone that she had won, she said, she thought it was a scam, or maybe she'd won something small, like $10. Just to satisfy her curiosity, she logged into her account and saw that she had matched four of the five numbers plus the Powerball in that second drawing. It would have been a $50,000 payout, but the multiplier tripled her winnings.

alternative_right shares a report from Phys.org: For the first time, a new study has tested the effectiveness of trigger warnings in real life scenarios, revealing that the vast majority of young adults choose to ignore them. A new Flinders University study has found that nearly 90% of young people who saw a trigger warning still chose to view the content, saying that they did so out of curiosity, rather than because they felt emotionally prepared or protected. The findings published in the Journal of Behavior Therapy and Experimental Psychiatry aligned with a growing body of lab-based research suggesting that trigger warnings rarely lead to the avoidance of potentially distressing material.

"We've decided to support image-based search," announced the product manager for Firefox Search. Powered by the AI-driven Google Lens search technology, they promise the new feature offers "a frictionless, fast, and a curiosity-sparking way to (as Google puts it) 'search what you see'." With just a right-click on any image, you'll be able to:

- Find similar products, places, or objects
- Copy, translate, or search text from images
- Get inspiration for learning, travel, or shopping

Look for the new "Search Image with Google Lens" option in your right-click menu (tagged with a NEW badge at first). This is a desktop-only feature, and it will start gradually rolling out worldwide. Note: Google must be set as your default search engine for this feature to appear.

We'll be listening closely to your feedback as we roll it out. Some of the things we're wondering about:

Does the placement in the context menu align with your expectations?
Would you prefer the option to choose your visual search provider?
Where else would you like entry points to visual search (e.g. when you open a new tab, in the address bar, on mobile devices, etc.)

We can't wait to hear your thoughts as the rollout begins!
Some thoughts from WebProNews: Mozilla emphasizes that this is an opt-in feature, giving users control over activation, which aligns with the company's longstanding commitment to privacy and user agency.

Yet, for industry observers, this partnership with Google raises intriguing questions about competitive dynamics in the browser space, where Firefox has historically positioned itself as an independent alternative to Chrome... This move comes at a time when browsers are increasingly becoming platforms for AI-driven enhancements, as evidenced by recent updates in competitors like Microsoft's Edge, which integrates Copilot AI. Mozilla's decision to leverage Google Lens rather than developing an in-house solution could be seen as a pragmatic step to accelerate feature parity, especially given Firefox's smaller market share. Insiders note that by tapping into established technologies, Mozilla can focus resources on core strengths like privacy protections, potentially attracting users disillusioned with data-heavy ecosystems... While mobile users might feel left out, the phased rollout over the next few weeks allows for feedback loops through community channels, a hallmark of Mozilla's open-source ethos.

Data from similar integrations in other browsers suggests visual search can boost engagement by 15-20%, per industry reports, though Mozilla has not disclosed specific metrics yet... Looking ahead, Mozilla's strategy appears geared toward incremental innovations that bolster user retention without alienating its privacy-focused base. If successful, this could help Firefox claw back some ground against Chrome's dominance, estimated at over 60% market share. For now, the feature's gradual deployment invites ongoing dialogue, underscoring Mozilla's community-driven model in an industry often criticized for top-down decisions.

After 26 years and over 1,000 episodes, Melvyn Bragg is stepping down as presenter of BBC Radio 4's In Our Time, leaving behind a legacy of intellectual curiosity and broadcasting excellence. While he will no longer host the series, he will remain involved with the BBC and is set to launch a new project in 2026. The BBC reports: Over the last quarter of a century, Melvyn has skilfully led conversations about everything from the age of the Universe to 'Zenobia', Queen of the Palmyrene Empire. He has welcomed the company of the brightest and best academics in their fields, sharing their passion and knowledge with a fascinated audience right around the globe. While he will be much missed on In Our Time, Melvyn will continue to be a friend of Radio 4 with more to come to celebrate his extraordinary career, and a new series in 2026 (details to be announced soon).

Melvyn Bragg says: "For a program with a wholly misleading title which started from scratch with a six-month contract, it's been quite a ride! I have worked with many extremely talented and helpful people inside the BBC as well as some of the greatest academics around the world. It's been a great privilege and pleasure. I much look forward to continuing to work for the BBC on Radio 4. Thank you for listening." [...] In Our Time will be back on Radio 4 with a new presenter who will be announced in due course.

Vivaldi CEO Jon von Tetzchner has doubled down on his company's refusal to integrate generative AI into its browser, arguing that embedding AI in browsing dehumanizes the web, funnels traffic away from publishers, and primarily serves to harvest user data. "Every startup is doing AI, and there is a push for AI inside products and services continuously," he told The Register in a phone interview. "It's not really focusing on what people need." The Register reports: On Thursday, Von Tetzchner published a blog post articulating his company's rejection of generative AI in the browser, reiterating concerns raised last year by Vivaldi software developer Julien Picalausa. [...] Von Tetzchner argues that relying on generative AI for browsing dehumanizes and impoverishes the web by diverting traffic away from publishers and onto chatbots. "We're taking a stand, choosing humans over hype, and we will not turn the joy of exploring into inactive spectatorship," he stated in his post. "Without exploration, the web becomes far less interesting. Our curiosity loses oxygen and the diversity of the web dies."

Von Tetzchner told The Register that almost all the users he hears from don't want AI in their browser. "I'm not so sure that applies to the general public, but I do think that actually most people are kind of wary of something that's always looking over your shoulder," he said. "And a lot of the systems as they're built today that's what they're doing. The reason why they're putting in the systems is to collect information." Von Tetzchner said that AI in browsers presents the same problem as social media algorithms that decide what people see based on collected data. Vivaldi, he said, wants users to control their own data and to make their own decisions about what they see. "We would like users to be in control," he said. "If people want to use AI as those services, it's easily accessible to them without building it into the browser. But I think the concept of building it into the browser is typically for the sake of collecting information. And that's not what we are about as a company, and we don't think that's what the web should be about."

Vivaldi is not against all uses of AI, and in fact uses it for in-browser translation. But these are premade models that don't rely on user data, von Tetzchner said. "It's not like we're saying AI is wrong in all cases," he said. "I think AI can be used in particular for things like research and the like. I think it has significant value in recognizing patterns and the like. But I think the way it is being used on the internet and for browsing is net negative."

"For a few dozen people in the world, the downside of living with a rare immune condition comes with a surprising superpower — the ability to fight off all viruses..." notes an announcement from Columbia University. "At first, the condition only seemed to increase vulnerability to some bacterial infections. But as more patients were identified, its unexpected antiviral benefits became apparent." Columbia immunologist Dusan Bogunovic discovered the individuals' antiviral powers about 15 years ago, soon after he identified the genetic mutation that causes the condition... Bogunovic, a professor of pediatric immunology at Columbia University's Vagelos College of Physicians and Surgeons, soon learned that everyone with the mutation, which causes a deficiency in an immune regulator called ISG15, has mild, but persistent systemic inflammation... "In the back of my mind, I kept thinking that if we could produce this type of light immune activation in other people, we could protect them from just about any virus," Bogunovic says.

Today, Bogunovic is closing in on a therapeutic strategy that could provide that broad-spectrum protection against viruses and become an important weapon in next pandemic. In his latest study, published August 13 in Science Translational Medicine, Bogunovic and his team report that an experimental therapy they've developed temporarily gives recipients (hamsters and mice, so far) the same antiviral superpower as people with ISG15 deficiency. When administered prophylactically into the animals' lungs via a nasal drip, the therapy prevented viral replication of influenza and SARS-CoV-2 viruses and lessened disease severity. In cell culture, "we have yet to find a virus that can break through the therapy's defenses," Bogunovic says...

Bogunovic's therapeutic turns on production of 10 proteins that are primarily responsible for the broad antiviral protection. The current design resembles COVID mRNA vaccines but with a twist: Ten mRNAs encoding the 10 proteins are packaged inside a lipid nanoparticle. Once the nanoparticles are absorbed by the recipient's cells, the cells generate the ten host proteins to produce the antiviral protection. "We only generate a small amount of these ten proteins, for a very short time, and that leads to much less inflammation than what we see in ISG15-deficient individuals," Bogunovic says. "But that inflammation is enough to prevent antiviral diseases...."

"We believe the technology will work even if we don't know the identity of the virus," Bogunovic says. Importantly, the antiviral protection provided by the technology will not prevent people from developing their own immunological memory to the virus for longer-term protection.
"Our findings reinforce the power of research driven by curiosity without preconceived notions," Bogunovic says in the announcement. "We were not looking for an antiviral when we began studying our rare patients, but the studies have inspired the potential development of a universal antiviral for everyone."

"James Cameron has a confession: he can't write Terminator 7..." according to the Guardian, "because reality keeps nicking his plotlines." "I'm at a point right now where I have a hard time writing science-fiction," Cameron told CNN this week. "I'm tasked with writing a new Terminator story [but] I don't know what to say that won't be overtaken by real events. We are living in a science-fiction age right now...."

What Cameron should be looking for is a complete system reboot to reinvigorate the saga in the way Prey brought fans back to Predator and Alien: Romulus restored interest in slimy Xenomorphs. All evidence suggests that the 70-year-old film-maker is far more interested in the current challenges surrounding AI, superintelligences and humankind's constant efforts to destroy itself, which doesn't exactly lend itself to the sort of back-to-basics, relentless-monsters-hunt-a-few-unlucky-humans-for-two-hours approach that has worked elsewhere. The challenge here seems to be to fuse Terminator's core DNA — unstoppable cyborgs, explosive chase sequences, and Sarah Connor-level defiance — with the occasionally rather more prosaic yet equally scary existential anxieties of 21st-century AI doom-mongering. So we may get Terminator 7: Kill List, in which a single, battered freedom fighter is hunted across a decimated city by a T-800 running a predictive policing algorithm that knows her next move before she does. Or T7: Singularity's Mom, in which a lone Sarah Connor-type must protect a teenage coder whose chatbot will one day evolve into Skynet. Or Terminator 7: Terms and Conditions, in which humanity's downfall comes not from nuclear warfare but from everyone absent-mindedly agreeing to Skynet's new privacy policy, triggering an army of leather-clad enforcers to collect on the fine print.

Or perhaps the future just looks terrifying enough without Cameron getting involved — which, rather worryingly for the future of the franchise, seems to be the director's essential point.
"The only way out is through," Cameron said in the CNN interview, "by using our intelligence, by using our curiosity, by using our command of technology, but also, by really understanding the stark probabilities that we face."

In the meantime, Cameron is working on a new film inspired by the book Ghosts of Hiroshima, a book written by Charles Pellegrino, one of the consultants on Titanic. "I know what a meticulous researcher he is," Cameron told CNN in a recent interview. (Transcript here.) CAMERON: He's talked about this book for ages and ages and sent me early versions of it. So, I've read it with interest, great interest a number of times now. What compels me out of all that and what I think the human hook for understanding this tragedy is, is to follow a handful, specifically two will be featured of survivors, that actually survived not only the Hiroshima blast, but then went to Nagasaki and three days later were hit again.... This film scares me. I fear making this film. I fear the images that I'm going to have to create, to be honest and to be truthful.
CNN also spoke to former U.S. Energy secretary Ernest Moni, who is now a CEO at the nonprofit global security organization, the Nuclear Threat Initiative: MONI: There remains a false narrative that the possession of these nuclear weapons is actually making us safer when they're not. That's the narrative I think, ultimately, we need to change. Harry Truman said, quite correctly, these nuclear weapons, they are not military weapons. Dropped on a city, they indiscriminately kill combatants, non-combatants, women, children, etc. They should not be thought of as military weapons, but as weapons of mass destruction, indiscriminate mass destruction when certainly dropped in an urban center.
Thanks to long-time Slashdot reader schwit1 for sharing the article.

"Search engines still require users to use critical thinking to interpret and contextualize the results," argues Aaron French, an assistant professor of information systems. But with the rise of generative AI tools like ChatGPT, "internet users aren't just outsourcing memory — they may be outsourcing thinking itself." Generative AI tools don't just retrieve information; they can create, analyze and summarize it. This represents a fundamental shift: Arguably, generative AI is the first technology that could replace human thinking and creativity.

That raises a critical question: Is ChatGPT making us stupid...?

[A]s many people increasingly delegate cognitive tasks to AI, I think it's worth considering what exactly we're gaining and what we are at risk of losing.
"For many, it's replacing the need to sift through sources, compare viewpoints and wrestle with ambiguity," the article argues, positing that this "may be weakening their ability to think critically, solve complex problems and engage deeply with information."

But in a section titled "AI and the Dunning-Kruger effect," he suggests "what matters isn't whether a person uses generative AI, but how. If used uncritically, ChatGPT can lead to intellectual complacency." His larger point seems to be that when used as an aid, AI "can become a powerful tool for stimulating curiosity, generating ideas, clarifying complex topics and provoking intellectual dialogue.... to augment human intelligence, not replace it. That means using ChatGPT to support inquiry, not to shortcut it. It means treating AI responses as the beginning of thought, not the end."

He believes mass adoption of generative AI has "left internet users at a crossroads. One path leads to intellectual decline: a world where we let AI do the thinking for us. The other offers an opportunity: to expand our brainpower by working in tandem with AI, leveraging its power to enhance our own." So his article ends with a question — how will we use AI to make us smarter?

Share your own thoughts and experiences in the comments. Do you think your AI use is making you smarter?

"I wonder who actually uses AI and why," writes Slashdot reader VertosCay: Out of pure curiosity, I have asked various AI models to create: simple Arduino code, business letters, real estate listing descriptions, and 3D models/vector art for various methods of manufacturing (3D printing, laser printing, CNC machining). None of it has been what I would call "turnkey". Everything required some form of correction or editing before it was usable.

So what's the point?
Their original submission includes more AI-related questions for Slashdot readers ("Do you use it? Why?") But their biggest question seems to be: "Do you have to correct it?"

And if that's the case, then when you add up all that correction time... "Is it actually helpful?"
