The face-off: AI versus rule-based scanners In the quiet, meticulous world of software security, two kinds of detectors keep watch over our code: the veteran static analyzers that run on rules, and the newer, flexible minds built from large language models. The former move like seasoned searchlights, scanning for known patterns of danger—SQL injections, hardcoded…
Knot theory often feels like a treasure map for loops: you search for patterns in entangled strands and the rules they obey when they twist and untwist. Torus knots, which wrap around a doughnut-shaped surface n times in one direction and m times in the other, sit on the frontier between computation and wonder. Their…
Can artificial intelligence truly understand the subtleties of human politics? A new study from the University of Copenhagen, led by Ilias Chalkidis, Stephanie Brandl, and Paris Aslanidis, throws cold water on that idea. Their research delves into the surprisingly complex task of using AI to identify populism in political speech, revealing unexpected limitations in even…
In the growing chorus of artificial intelligence that can describe a photo, translate a caption, or answer a riddle about a chart, a stubborn question keeps echoing: can these systems really combine multiple skills at once, or do they stumble when the task demands several abilities at the same time? It’s a bit like asking…
Imagine a drum, taut and ready to resonate. Now, imagine we want to muffle its sound, not by damping the drumhead, but by strategically placing an almost invisible obstacle inside. The question is: where should that tiny obstruction go to produce the greatest silencing effect? The Mathematical Drum This seemingly simple puzzle forms the core…
When researchers peek at the vast universe of all possible rules that could relate a handful of items, they often discover that the most famous ideas travel across boundaries—from pure math to computer science to everyday intuition. A recent study by Rudolf Berghammer of Kiel, Jules Desharnais of Université Laval, and Michael Winter of Brock…
When a politician speaks, cameras capture the moment; when those moments travel through the internet, they can be rewritten in the blink of an editing tool. Deepfakes have moved from curiosities to everyday threats, and the question isn’t whether we can detect fakes after they arrive, but how to prevent them from being born in…
Cinematography is the language that makes a frame more than a snapshot. It’s the grammar of where the camera sits, how wide the world feels, when the light leans in, and how a scene tells you where to look next. In the modern era, vision-language models (VLMs) have learned to describe images and even generate…
The night sky keeps its secrets in milky whispers, especially in its bustling nurseries of young stars. For years, astronomers have watched star clusters light up in surprising ways: splits in their main sequences, and elongated turns in their evolutionary diagrams that hint at more than a single way to grow up. A recent study…
Underground mines are like hidden cities carved into rock, where the air is thick with dust, temperatures swing like weather vanes, and danger can arrive as quietly as a murmur in the dark. When things go wrong, seconds count and visibility can vanish in smoke, vibration, or dust. In that high-stakes void, robots and smart…
Universality Hidden in Noise In the quiet mathematics of quantum physics, noise usually seems like a villain: it spoils delicate quantum effects, blurs interference patterns, and makes clean predictions slip through our fingers. Costa, Ribeiro, and De Luca flip that script. They investigate a one‑dimensional chain of free (non‑interacting) fermions subjected to different forms of…
Imagine a world where even the most battered, low-resolution recording devices could capture crystal-clear audio, filtering out background noise and interference with stunning accuracy. This isn’t science fiction; it’s the promise of a new approach to signal processing developed by researchers at Rutgers University. Led by Morriel Kasher, Michael Tinston, and Predrag Spasojevic, their work…
On a quiet afternoon, you walk into a living room and your brain instantly sketches a map: a chair tucked beside a coffee table, a plant basking in the corner, the TV mounted above a console. You can tell who’s where, who’s touching whom, and even how close one thing sits to another. That effortless…
In the race to render photorealistic scenes at interactive speeds, the shape of a single bounding box can decide whether a scene feels instant or stuttery. Real-time ray tracing hinges on a data structure called a bounding volume hierarchy, or BVH, to decide quickly which objects a ray might hit. The tighter the bounding volumes,…
Space near the most extreme objects in the universe behaves like a carnival mirror: it twists light, stretches time, and turns simple paths into elaborate loops. Around massive, compact bodies, photons can get stuck in orbit, tracing circles that look almost musical in their precision. These light rings, or null circular geodesics, are more than…
Intro Large language models have become the modern wild west of text: powerful, versatile, and increasingly hard to pin down. As their capabilities scale, so do the tricks people devise to coax them into saying or doing things their designers don’t intend. Among the cleverest strategies are obfuscation-based jailbreaks, where a malicious request is hidden…
Numbers, those seemingly immutable pillars of reality, often harbor hidden depths. We use them to measure, count, and define the world around us, but sometimes, mathematicians turn the lens inward, exploring the strange, self-referential properties that numbers possess. A new study from Ningbo University in China dives into one such peculiar corner of number theory,…
Online disinformation is not just a matter of wrong facts; it’s an emotion machine. Anger, outrage, and fear propel shares faster than any truth check can catch up. In Japan, researchers at the Institute of Information Security in Yokohama have tested a new approach that targets the moment of sharing, not the post after it…
In labs and on laptops, researchers chase a new kind of lab partner: a tool that can read a paper, translate its methods into code, set up experiments, and tell us what happened. The dream sounds like science fiction until a flood of AI systems, many built on large language models, makes it feel almost…
In the vast, buzzing world of distributed computers, every participant carries a fingerprint—an identity that helps everyone coordinate, compete, and survive. When a system wants to rename those fingerprints, it’s not enough to hand out new numbers. The new identities must be unique, fit into a smaller pool than the original, and ideally preserve the…
