The researchers behind this work hail from the Institute of Applied Physics and Computational Mathematics in Beijing, with collaborators at Tsinghua University. Led by Tianhao Liu and Linjie Song, and including Qiaoran Wu and Wenming Zou, the team tackles a striking question about how many distinct states can exist when several quantum fluids share a…
Glimmers of a future where software not only speaks in confident sentences but actually plans, reasons, and orchestrates real-world labs aren’t just sci‑fi. A team led by Purdue University chemist Gaurav Chopra has built SciBORG, a modular framework that lets large language model (LLM) powered agents plan, reason, and execute long, multi-step scientific tasks while…
Imagine a world where software bugs fix themselves. Not magically, of course, but through the power of artificial intelligence. That future is closer than you might think, thanks to a new technique developed by researchers at the University of Waterloo, Canada. Their approach, called AssertFlip, uses large language models (LLMs) to automatically generate tests that…
Imagine a microscopic dance, a precise ballet of radiation, targeting a tumor with the grace of a surgeon’s scalpel. This is the essence of brachytherapy, a cancer treatment where radioactive sources are carefully placed near tumors. While incredibly effective, planning this procedure is incredibly challenging and time-consuming –– until now. Researchers at Leiden University Medical…
In mathematics, researchers sometimes borrow a familiar map and aim it at a wild, alien landscape. Guirardel and Perin take the well-trodden idea of an algebraic group and ask a bold question: what happens when the field is replaced by a group, specifically a torsion-free hyperbolic group? The answer, surprisingly orderly, reads like a structural…
In the world of computer vision, turning a handful of photos into a believable map of the world is like assembling a city skyline from silhouettes. The problem is not just about finding where all the buildings stand, but about knowing what the buildings’ sizes and angles really are. If you don’t know exactly how…
Why Detecting Anomalies Is More Than Just Spotting a Needle in a Haystack In the world of artificial intelligence, teaching machines to recognize when something is off—an anomaly—is a bit like training a guard dog to bark only at strangers, not family members. But what if the dog doesn’t know who the family is? This…
In the quiet, gnawing world of stomach cancer, catching a tumor early can be the difference between a slim chance and a survivable one. Gastric cancer remains a major global killer, and the early, subtle signs are easy to miss. A new study from a consortium led by the University of Macau proposes a bold…
Gravity is not just a tug of war. In the crowded nursery where young stars keep company with gas, dust, and newborn planets, the frame you pick to describe the motion can tilt the entire story. The latest work from a collaboration led by Aure9lien Crida at Universite9 Cf4te db4Azur (Observatoire de la Cf4te db4Azur)…
A New Four-Loop Calculation: Peering Deeper into the Quantum Realm Quantum field theories (QFTs) are the fundamental language of particle physics, describing how particles interact at the most basic level. Think of them as incredibly detailed recipes for the universe, specifying how different ingredients (particles) combine to form all the phenomena we observe. One crucial…
The dream of a seamless digital assistant, a sort of modern-day JARVIS, is closer than you might think. But a new benchmark from researchers at Fudan University, Shanghai AI Lab, and the University of Hong Kong reveals a surprising truth: even the most advanced AI agents are surprisingly clumsy when it comes to handling everyday…
Invisible Borders in the Underworld We tend to think of property rights as a hallmark of civilization—legal titles, deeds, and courts that keep disputes from turning violent. But what happens when the law steps aside? In the shadowy world of organized crime, especially in urban drug markets, property rights don’t vanish; they morph into informal,…
In biology labs around the world, the humble light microscope is a constant companion. It’s quick, cheap, and can reveal the tiny architecture of a cell, a neuron, or a budding organoid. But the very physics that makes it accessible also makes it hard to trust what you see. Widefield microscopes, the kind that sit…
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…
Three-dimensional quantum matter hides strange creatures called fractons, excitations so oddly tethered to their surroundings that they barely move unless they team up with others. In the wild world of fracton phases, some particles can glide within planes, others crawl along lines, and some are stuck unless they’re joined with the right partners. The paper…
High in the ladder of abstraction, mathematics sometimes feels like mapping weather on a planet we can barely glimpse. You’re looking at a landscape made of equations, curves, and angles, and yet the real drama happens behind the scenes. For a certain class of geometric shapes called projective hypersurfaces, the weather is written in derivatives:…
The Hunt for Habitable Worlds: A Cosmic Treasure Hunt Imagine a vast, star-studded ocean, each star a sun potentially harboring planets. For decades, we’ve known exoplanets exist, worlds orbiting distant suns. But finding truly Earth-like planets — those with conditions potentially suitable for life — remains a holy grail of astronomy. A new report from…
Physicists are chasing gamma rays bright enough to cut through copper, yet produced in a device small enough to fit in a university lab. The latest result from a multinational team led by E. Gerstmayr at Queen’s University Belfast shows that a single petawatt‑class laser can, in a span of tens of femtoseconds, conjure a…
Beta decay is one of those quiet keystones of physics. It’s the process by which a neutron turns into a proton, an electron, and a ghostly neutrino, a tiny rearrangement that reverberates from the heart of atoms to the fabric of the cosmos. For decades, scientists have used clever tricks to predict how fast these…
In a new working paper, Ted Sichelman, a professor of law at the University of San Diego, asks a bold question: what if the laws that govern physical reality themselves have orders—first order, second order, and beyond—just like social rules do? His central idea is not that the cosmos is lawless, but that physical law…
