The 7-24 GHz Gap: A 6G Bottleneck The airwaves hum with data. Every decade, a new generation of cellular technology arrives, promising faster speeds and greater connectivity. But this progress isn’t a smooth, upward trajectory; it’s a series of leaps and bounds, punctuated by moments of intense engineering problem-solving. Right now, the wireless world is…
Why Tibetan Is the Next Frontier for Language AI In the sprawling landscape of artificial intelligence, the spotlight often shines on languages like English, Chinese, or Spanish—languages with millions of digital footprints and oceans of data. But what happens when AI tries to learn a language spoken by millions yet barely represented online? Tibetan, with…
The Unexpected Persistence of Heat Imagine a ripple spreading across a still pond. The initial disturbance dictates the shape and spread of the waves. Similarly, in the world of heat equations, the initial conditions—how temperature is distributed at the outset—heavily influence how heat diffuses over time. A new study from the Australian National University, led…
When a therapist asks you to tell your story, you expect more than polite phrases and quick fixes. You want a partner who hears you—not just the words you say, but the hesitations you swallow, the silences you fear, and the values you’re trying to protect. A study published in 2025, led by Keita Kiuchi…
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…
Waiting-Only Broadcasts Turn Hard Verification into a Solvable Puzzle In a world where billions of devices whisper to one another at once, the question of whether a distributed protocol behaves the way we intend becomes almost a public-transport puzzle: too many moving parts, too many possible paths, and a clock that never stops. The new…
Intro — a quiet harmony inside cryptography’s wild algebra Boolean functions are the backstage crew of modern cryptography: tiny, binary machines that help scramble and unscramble information in ways that look random but are governed by precise rules. Among these, a special breed called bent functions stands out for its perfect nonlinear charm. They’re the…
Cosmology keeps bouncing between elegant ideas and stubborn facts. The universe’s accelerating expansion is one of those stubborn facts, a puzzle that makes physicists reach for big ideas and clever math. One recent twist adds a dose of geometry to the mix: could the shape of space itself, including dimensions we don’t directly experience, be…
Imagine a perfectly balanced scale, where each side represents a different aspect of a mathematical structure. This analogy, while imperfect, helps capture the essence of Sudeshna Basu’s groundbreaking work on Banach spaces, a field of mathematics dealing with abstract vector spaces. Basu’s research, conducted while visiting the National Institute of Science Education and Research Bhubaneshwar,…
The hum of the engine, the rush of the highway—driving is a symphony of sensations. But what if your car could understand not just your actions, but your inner state? What if it could detect subtle shifts in your physiology, your stress levels, even your fatigue, before you consciously realize them yourself? A New Window…
On the surface, a thin film laced with tiny, highly polarizable inclusions might look like a quiet stage for basic physics. Yet when you shine an electric field perpendicular to that film, the system begins to perform a surprisingly elaborate dance. The lead performers are dipoles—tiny magnetic or electric moments that arise in response to…
Why Protein Sequencing Feels Like a Puzzle Missing Pieces Proteins are the molecular machines of life, but unlike DNA, reading their sequences is a bit like trying to solve a jigsaw puzzle with many pieces hidden or erased. While DNA sequencing has leapt forward with technologies that read single molecules, protein sequencing still struggles with…
In the dance of video understanding, the hardest partner isn’t the neural network or the language model at the end of the chain. It’s the tokens—the little bits of visual information the model carries from frame to frame. Each video yields a torrent of tokens, and even sampling a handful of frames can explode into…
Researchers at the Indian Institute of Technology Madras have developed a groundbreaking artificial intelligence model that can accurately predict the properties and stability of titanium nitride (Ti-N) compounds. This seemingly niche achievement ripples far beyond the lab, potentially impacting everything from aerospace engineering to the design of medical implants. The Titanium Nitride Enigma Titanium nitride…
Selmer Towers Stabilize in Function Field Arithmetic Across Neighborhoods The language of arithmetic is older than memory and yet the modern versions keep surprising us with new rooms to explore. In the world of number theory, Iwasawa theory studies how arithmetic information grows as you climb towers of field extensions, especially those tied to a…
Imagine a world where eye exams could reveal hidden diseases, not just through what your doctor sees, but through intricate patterns invisible to the naked eye. That future might be closer than we think, thanks to a groundbreaking study by researchers at Zhejiang Normal University and Wenzhou Medical University, led by Shoujun Huang and Qi…
Video compression has always been a guessing game between how little you can store and how good the picture looks when you pull it back. The newest twist flips the coin: instead of storing a movie frame as a mosaic of pixels, you train a tiny neural network to learn how to draw the scene…
Generative AI has a talent for spotting patterns in images, texts, and sounds, but it still depends on the right kind of training material. The right kind is not just a pile of pictures or sheets; it is data that respects the structure of what it represents. VisionScores is a bold attempt to give machines…
The tiny stage is a metal surface, the performer a single electron spin pinned to a defect or molecule, and the spotlight is an electric field that can coax the spin to dance. In this world, researchers aren’t just watching quantum quirks; they’re designing the choreography with electric pulses, no magnetic coils required. The paper…
Highlights of a Hidden Force Highlights: Magnetic fields thread stars as quietly as gravity threads planets, yet they sculpt their winds, pulsations, and destinies. A small, stubborn fraction of massive stars carry fossil magnetic fields at their surfaces, unlike the sun’s dynamo-generated magnetism. By watching how light splits, polarizes, and shifts as stars spin, scientists…
