Fermilab’s computing grid is more than a tech stack. It’s a living artery that pumps data, software, and collaboration across continents, fueling experiments that probe the mysteries of matter, energy, and the cosmos. For decades, the grid trusted users and machines through X.509 certificates—digital passports that could be shared and extended, but eventually grew unwieldy…
Imagine a speck of dust adrift in the inky blackness of space, colder than anything you can fathom. This isn’t just any dust; it’s the seed of a potential world, coated in a fragile layer of ice. On these icy mantles, molecules dance a slow, frozen ballet, sometimes sticking around, sometimes flitting back into the…
The world isn’t made of isolated particles; it’s a dizzying dance of interactions. We tend to think in terms of pairs: two molecules attracting, two magnets repelling. But what happens when a third body waltzes into the scene? A new study from Auburn University reveals a surprising truth about these so-called “three-body effects,” specifically on…
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 the endless maze of real‑world decision making, some puzzles are simple to state but brutally hard to solve. You want to assign 0s and 1s to a set of items — binary decisions — while also obeying a handful of rules that link those choices together. Think facility location, scheduling, or even how to…
The Large Hadron Collider keeps throwing curves at our understanding of the tiniest building blocks. Among the most intriguing players on the stage are the top quarks, heavy enough to act like test particles for the quantum rules that bind the subatomic world. Their spins don’t just flip and flop in isolation; they whisper about…
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,…
In the wild, a single photograph can be a tangle of meanings: the color blue can describe a sky, a blueberry, or a bruise on a tired face. Our brains navigate that mess by grouping related ideas and then recombining them on the fly. A recent line of work in artificial intelligence taps into that…
The world of abstract algebra often hides its deepest truths behind plain symbols and rules. Groups, at their core, are a language for symmetry: a way to describe how objects can be rearranged, twisted, or swapped and still behave like the same underlying system. The Andrews-Curtis transformations are a tiny, carefully defined toolkit within that…
Graphs aren’t just dry drawings in a math textbook; they’re living maps of real networks—how information travels, how power lines connect, how communities form and split. One of computer science’ oldest thrills is a puzzle that sounds simple on paper but hides a surprising depth: given a network with a handful of special points—terminals—how can…
On a noisy factory floor, a machine’s heartbeat can reveal looming trouble long before a bolt squeals. Engineers have long used spectrograms—visuals that turn sound into a weather map of frequencies over time—to listen in on that heartbeat. But turning a spectrogram into a trustworthy alarm has always been part science, part art. The study…
In the race to build cars that can drive themselves, engineers juggle more variables than a cockpit full of dials. Not only must the software manage steering, speed, and braking, it has to do so across a spectrum of hardware: different sensors that glimpse the road, varying actuators that respond at different speeds, and a…
In the world of real time optimization, engineers chase the best operating point for sprawling systems—think power grids, supply chains, and even the algorithms that steer your favorite apps. The catch is simple and stubborn: you rarely know the full map from input to output. You only glimpse a sliver of it through measurements, and…
The Untapped Potential of African Languages Africa, a continent pulsating with a vibrant tapestry of over 2,300 languages, has largely remained unheard in the digital world. Speech technology—the ability of computers to understand and generate human speech—has primarily focused on a handful of dominant languages, leaving a vast linguistic landscape unexplored. This digital silence excludes…
Generative AI has become a kind of writing partner—glued to keyboards, churning ideas, shaping paragraphs with a speed that feels almost magical. But beneath the flash of fluent text lies a stubborn bottleneck: the way most large language models generate one token at a time, strictly in sequence. A team from Nanjing University in China…
Wormholes have always hovered between science and myth—the imagined tunnels through spacetime that could, in principle, connect distant regions of the cosmos. A new study from the University of Texas at Dallas, led by Travis Rippentrop, Avijit Bera, and Mustapha Ishak, digs into a pressing question behind that science-fiction gloss: can these thin-walled bridges stay…
Demokritos National Research Center in Athens, Greece, home to the Institute of Nuclear and Particle Physics, is where George Savvidy and colleagues push the boundaries of how we describe massless particles. In a study threaded through the language of non-commutative geometry and deep symmetry, the author explores how photons and gravitons—the massless quanta of light…
The unbounded world of real numbers has a nasty habit: functions can surge to infinity on one side and vanish on the other. Classical polynomials, the workhorses of approximation theory, stumble when faced with that asymmetry. In a striking synthesis of old theory and modern computation, Kingsley Yeon of the University of Chicago and Steven…
Graphs are the scuffed, sprawling maps of the modern information era. They stitch together people, papers, products, and places with threads that can carry tone, time, and intention. But the real world isn’t tidy. It throws curveballs in the form of out-of-distribution, or OOD, nodes—points that don’t quite fit the patterns the model was trained…
In chemistry, reactions often feel like a walk along a map where the ground rules are supposed to be carved in stone. You follow a surface, you cross a barrier, and you measure a rate. But the quantum world isn’t content with neat maps. It braids together zero-point motion, tunneling through barriers, and sudden hops…
