Harvard Paper Explores Possibility That Object Approaching From Beyond Solar System Is Hostile Alien Technology

A strange interstellar object is hurtling its way toward our pale blue dot — and according to a Harvard astronomer, there's a chance it's not a benign asteroid or comet, but instead some harmful form of alien tech. In a new, yet-to-be-peer-reviewed paper, Harvard astronomer Avi Loeb — the same scientist who suggested that 'Oumuamua, the first interstellar object ever detected back in 2017, was alien in nature — teamed up with researchers from the Britain-based Initiative for Interstellar Studie

Top AI Researchers Concerned They’re Losing the Ability to Understand What They’ve Created

Researchers from OpenAI, Google DeepMind, and Meta have joined forces to warn about what they're building. In a new position paper, 40 researchers spread across those four companies called for more investigation of AI powered by so-called "chains-of-thought" (CoT), the "thinking out loud" process that advanced "reasoning" models — the current vanguard of consumer-facing AI — use when they're working through a query. As those researchers acknowledge, CoTs add a certain transparency into the inn

Team AA: Here are our favorite phone wallpapers

Hadlee Simons / Android Authority Whether it’s our weekly Wallpaper Wednesday series or backgrounds from specific devices, we’re all about sharing wallpapers with you folks. But what are our favorite wallpapers that we use on our own Android phones? Well, I asked the Android Authority team for their favorite backgrounds. Some team members used wallpapers showing their loved ones and were thus unable to share their backgrounds. Fortunately, we still had more than a few cool submissions from oth

Research leaders urge tech industry to monitor AI’s ‘thoughts’

AI researchers from OpenAI, Google DeepMind, Anthropic, as well as a broad coalition of companies and nonprofit groups, are calling for deeper investigation into techniques for monitoring the so-called thoughts of AI reasoning models in a position paper published Tuesday. A key feature of AI reasoning models, such as OpenAI’s o3 and DeepSeek’s R1, are their chains-of-thought or CoTs — an externalized process in which AI models work through problems, similar to how humans use a scratch pad to wo

Scientists Are Sneaking Passages Into Research Papers Designed to Trick AI Reviewers

Artificial intelligence has infected every corner of academia — and now, some scientists are fighting back with a seriously weird trick. In a new investigation, reporters from Japan's Nikkei Asia found more than a dozen academic papers that contained invisible prompts meant to trick AI review tools into giving them glowing write-ups. Examining the academic database arXiv, where researchers publish studies awaiting peer review, Nikkei found 17 English-language papers from 14 separate institutio

Could a Paper Plane Thrown from the ISS Survive the Flight?

Sometimes there are profound questions in life that must be answered, like "What is the meaning of existence?", "Are we alone in the universe?" or "What happens if you throw a paper airplane from the International Space Station?" Luckily, that third one has finally been answered, because of course someone would eventually. A new paper from Maximilien Berthet and Kojiro Suzuki from the University of Tokyo looks at "the dynamics of an origami space plane during Earth atmospheric reentry" – in ot

AI could help humans copilot space missions one day, researchers find

Ignatiev/Getty Images Sci-fi authors and screenwriters have long envisioned AI companions helping humans as they explore the cosmos. Sometimes things go well (Commander Data was a friendly and reliable Starfleet officer), other times not so much ("I'm afraid I can't do that, Dave"). Now, AI-assisted spacefaring -- like so many other concepts that, not so long ago, seemed utterly far-fetched -- could soon become a practical reality.

Researchers seek to influence peer review with hidden AI prompts

In Brief Academics may be leaning on a novel strategy to influence peer review of their research papers — adding hidden prompts designed to coax AI tools to deliver positive feedback. Nikkei Asia reports that when examining English-language preprint papers available on the website arXiv, it found 17 papers that included some form of hidden AI prompt. The paper’s authors were affiliated with 14 academic institutions in eight countries, including Japan’s Waseda University and South Korea’s KAIST

Is It Cake? How Our Brain Deciphers Materials

One of the greatest questions of the modern age is: Is it cake? As in: Is it an espresso machine, or cake? Paint can, or cake? Air fryer, or …? Millions of viewers have watched rapt as TikTok bakers slice or bite into inedible-looking objects with fluffy, frosting-filled innards … or have tuned into Is It Cake?, the aptly named Netflix show. Why? As a form of entertainment, this kind of visual trick is hardly new. For centuries, artists have delighted in fooling us into thinking one material is

Bombshell Research Finds a Staggering Number of Scientific Papers Were AI-Generated

Like any crappy human writer, AI chatbots have a tendency to overuse specific words — and now, scientists are using that propensity to catch their colleagues when they secretly use it in their work. As the New York Times reports, scientists estimate, based on an analysis of those overused terms, that there could already be hundreds of thousands of academic papers written with the assistance of AI. In a new study published in the journal Science Advances, researchers from Germany's University o

What Apple's controversial research paper really tells us about LLMs

CHRISTOPH BURGSTEDT/SCIENCE PHOTO LIBRARY/Getty Generative AI models quickly proved they were capable of performing technical tasks well. Adding reasoning capabilities to the models unlocked unforeseen capabilities, enabling the models to think through more complex questions and produce better-quality, more accurate responses -- or so we thought. Last week, Apple released a research report called "The Illusion of Thinking: Understanding the Strengths and Limitations of Reasoning Models via the

Mathematical Illustrations: A Manual of Geometry and PostScript

This manual has been available on this site since about 1996, with improvements taking place frequently. The current version has been published as a book of about 350 pages by Cambridge University Press. By agreement with the Press, however, it will remain posted on this web site. Many improvements in the current version over previous ones are due to the (anonymous) referees of the Press, whom I wish to thank heartily. I also wish to thank Lauren Cowles, of the New York office of the Press, for
