Across the airwaves that knit our connected world, energy use is the quiet cost of speed. Bands get crowded, signals race through cities, and the hardware at the edge chews power to keep everything crisp. A new line of research argues we can cut waste not by adding more boxes but by rethinking how the…
In a world where a satellite can beam VPN-level upgrades to a smartphone, the future of connectivity depends on more than just faster chips or clever apps. It hinges on a big question: how do you design a network that spans space, air, and ground—three very different kinds of reality—without losing track of who talks…
The latest work from IIT Madras researchers Suresh Govindarajan and Jagannath Santara digs into the math‑heavy heart of two‑dimensional quantum theories. It sits at the crossroads of abstract number theory and the physics of tiny, symmetrical universes. Their arena is the holomorphic modular bootstrap, a method born to classify rational conformal field theories by reading…
Foundations Enter Pathology, Changing the Data Game Highlights: Big neural networks trained on unlabeled data can unlock delicate pathology tasks with far less labeled data. When you look at a whole slide image from a tumor tissue, you’re staring at a billion little pixels that tell a story—one that pathologists have learned to read through…
Why rounding numbers is just the start We all know that computers can’t store numbers with infinite precision. They round, truncate, and approximate. But what happens when the object we want to store isn’t a single number but a whole probability distribution? This is the challenge tackled by March T. Boedihardjo at Michigan State University…
In the heart of CERN’s sprawling accelerator complex, protons collide with ferocity, and the universe reveals its tiniest secrets in flashes of light and spray of particles. The LHCb experiment isn’t chasing the famous Higgs particle this time; it’s listening for whispers from quarks—the fundamental building blocks of matter—that rarely survive long enough to become…
In the quantum world, information can get lost not in a single puff of dust but through a slow, intricate tangle of interactions. It’s like dropping a spark into a crowded ballroom: the spark travels, flickers away, and reappears elsewhere, not as a neat message but as a sprawling pattern that’s almost impossible to follow…
From the sky, the world collapses into a mosaic of roads, rooftops, and moving silhouettes. Unmanned aerial vehicles, or UAVs, promise a kind of overhead commonsense: see more, cover more ground, react faster. Yet teaching a fleet of drones to understand a scene together while talking a language that doesn’t drown in data is a…
In the sprawling, unseen choreography of the Internet, traffic engineering is the conductor. It tries to route flows across a web of cables and satellites so that apps don’t stall, videos don’t freeze, and cloud services don’t grind to a halt. As networks grow from thousands to millions of links—think cloud WANs, data-center fabrics, and…
The Puzzle of Perfect Approximation At the heart of mathematics lies a deceptively simple question: how well can we approximate real numbers by rational ones? This question, which echoes through centuries of mathematical thought, is the essence of Diophantine approximation. It’s about finding integer solutions that come tantalizingly close to hitting a target defined by…
The paper you’re about to read asks a deceptively simple question: does tossing more predictors into a model always improve forecasts, especially when the world around us keeps changing? In finance, where regimes flip from calm to chaotic as fast as a quarterly report drops, the answer is almost certainly not. The authors show that…
Statistics has a habit—p-values hum in the background, guiding decisions with a number that is easy to misread. The new work from East Carolina University’s Department of Public Health, led by Paul W. Vos, proposes a reframing: a universal scale for test statistics that makes the extremeness of data feel tangible, whether you’re looking at…
In a world racing toward smarter devices, the challenge isn’t just collecting data but turning it into quick, trustworthy decisions where they matter most. Imagine autonomous vehicles, delivery drones, or factory robots that must both feel their surroundings and decide what to do in the blink of an eye. A new study from a team…
The night sky hides a slow, patient chorus. Among the many voices, carbon-rich stars on the edge of life—giant stars that puff out smoky, carbon-filled dust—sing in a dusty, infrared whisper. In the Large Magellanic Cloud, a nearby dwarf galaxy neighbor of our Milky Way, these stars offer a particularly rich concert. Their infrared glow…
The Big Bang theory, while remarkably successful, has some nagging inconsistencies. One of the most puzzling is the unexpected uniformity of the cosmic microwave background (CMB) radiation—the afterglow of the Big Bang. This uniformity suggests a period of incredibly rapid expansion known as inflation, but the details of inflation remain mysterious. A Missing Piece of…
The room is quiet, and the two strangers sit across from each other, one weaving a story, the other probing with questions. For a long time, humans have tried to read deception from tiny, flickering signs: a flick of the eye, a hesitant pause, a slight tremor in the voice. The new study from Stockholm…
The entanglement entropy you’ve heard about is a way to measure how tangled quantum systems are with each other. It’s a concept that has lit up discussions in quantum field theory, quantum gravity, and holography. But when you bring gauge symmetry into the picture—think of electromagnetism, or the color forces of quantum chromodynamics—the usual recipe…
In the data-hungry world of modern AI, there’s a quiet revolution happening at the edge: federated learning, where many devices collaborate to train a shared model without handing over their private data. It sounds perfect on paper, but the wireless airwaves that carry gradients and updates aren’t private by default. Signals broadcast in the open…
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…
Imagine watching a video where a dog smoothly transforms into a cat, or a forest scene melts into a snowy landscape with seamless grace. What was once the domain of painstaking animation is now within reach, thanks to a new AI framework developed at Nanyang Technological University and ByteDance Inc., led by researchers Zuhao Yang,…
