The city is a living organism, its streets veins through which countless vehicles, pedestrians, and buses move in a rhythm that never quite repeats. Researchers are getting closer to giving traffic signals a form of perception—so they can respond not just to a fixed script, but to the actual beat of daily life. A recent…
When a class of budding programmers hands in a program, the scene in the grading room often resembles a cross between detective work and interpretation. You don’t just check if the code runs; you sift through intent, strategy, and the student’s grasp of a concept. In a striking study from BITS Pilani in Pilani, India,…
Highlights A new statistical approach makes externally controlled single-arm trials more trustworthy by marrying two ideas: balancing covariates to mimic a randomized comparison, and modeling outcomes to guard against misspecification. The result is a doubly robust method that performs well when either the covariate balance model or the outcome model is correct, improving precision and…
The Electron–Ion Collider project at Brookhaven National Laboratory is blueprinted to push photons and protons into one tunnel and coax them to behave. At the heart of that ambition lies a delicate balancing act in the Hadron Storage Ring, in a cooling section known as IR2, where electrons and hadrons ride together to reduce the…
In the quiet, exacting world of functional analysis, a single vector can host an entire drama of motion. Apply a linear operator to it again and again, and watch the orbit wander through the space like a restless traveler mapping out every street corner. If that traveler visits every neighborhood, frequently enough, we call the…
The classroom of the near future isn’t just a room with a whiteboard and a projector. It’s a place where conversation with a computer — a chatty, patient, endlessly available helper — can reshape how students learn. The surge of generative AI tools like ChatGPT has flipped the script on study habits, prompts, and even…
In many physical problems, a boundary isn’t just a line on a map; it’s a stage that reshapes the entire drama. The fractional Laplacian, a mathematical gadget that captures how things hop, wiggle, or spread in space with a nonlocal twist, plays nicely on an infinite plane but behaves very differently when you confine it…
In the quiet corners of mathematics where shapes grow teeth and personality, convex lattice polytopes are not just pretty pictures. They are shapes built from the integer grid, with vertices sitting neatly on lattice points. Think of them as geometric fossils shaped by the arithmetic of Z4 or Z3 and so on, where every corner…
Imagine a world where translating between any two languages is as effortless as a casual conversation. That’s the ultimate goal driving researchers in the field of natural language processing (NLP), a quest complicated by the sheer number of languages spoken around the globe—over 7,000, to be exact. The Language Barrier: A Mountain to Climb Current…
Self- Calibration Might Unmask the True Cosmic Shear Signal Cosmic shear is one of the gentlest, most telling shadows in the night sky. It’s the subtle warping of distant galaxies as their light threads through the invisible web of dark matter. When scientists map this distortion across the sky, they’re effectively sketching the distribution of…
Imagine a crowded highway where cars can only travel in specific lanes. That’s similar to how optical fibers, the backbone of the internet, transmit data. Each ‘lane,’ or wavelength, carries a stream of information. As our demand for bandwidth explodes, we need better ways to manage and direct this flow of light. One promising solution…
A Big Challenge for Soft Robots Soft robots promise a gentler touch, resilience to impact, and a kind of adaptability that rigid machines can only envy. But as these squishy machines scale from cute centimeter toys to meter-long tools for real work, control stops being a neat afterthought and becomes the whole game. Pneumatic actuation—blasting…
The circle group is more than a pretty metaphor for a clock face. It’s a compact, beloved stage for ideas at the heart of algebra, analysis and topology. On that stage, points sit around a circle, and sequences of integers push those points along, sometimes nudging them toward zero, sometimes nudging them away. In a…
In the whirl of a city’s daily traffic, cameras don’t just capture chaos; they catalogue patterns. Most systems for watching video learn what normal looks like and flag anything that strays. But anomalies aren’t always dramatic plot twists. They hide in subtle pockets of a scene, a motion that refuses to conform, or a glimpse…
The world is messy. Reinforcement learning (RL), a powerful technique for training AI agents, has shown remarkable success in controlled environments like video games. But real-world scenarios are rarely so neat. Robots break down. Traffic patterns shift. User preferences evolve. How do you build an AI that can handle these unpredictable variations – without explicitly…
A New Way to Decode Wireless Channels Without Breaking a Sweat Wireless networks are the hidden nervous system of our digital lives. They must keep up with people who move, cars that zip by, and devices that wander through crowded streets. In practice, that means the radio channel—the way the air reshapes a signal as…
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…
Counting people in a photo isn’t just a nerdy puzzle; it’s a real‑world skein of tiny decisions: who counts, who’s occluded, where a group ends and a stray limb begins. For years, researchers trained counting systems with a blunt signal: either the count was right, or it wasn’t. But in messy scenes—dense crowds, shifting light,…
The moment you ask a smart assistant to draft something, you’re stepping into a tiny social experiment. The model replies, you point out what’s off, and suddenly the exchange isn’t a single push toward an answer but a back-and-forth dance toward a better one. Real conversations with AI rarely land in a neat one-shot victory;…
The Large Hadron Collider is a machine built for big questions and tiny clues. The Standard Model has steered physics for decades, but as scientists push its boundaries, they keep returning to the same stubborn mystery: what lies beyond the known particles and forces? A new analysis from the ATLAS Collaboration at CERN takes a…
