Can a large language model (LLM) truly understand code, or does it merely mimic the appearance of comprehension? This question lies at the heart of a new study from Zhejiang University and University College London, which introduces CodeReasoner, a novel framework that significantly boosts the code reasoning abilities of LLMs. The researchers, led by Lingfeng…
The Uncanny Valley of Conversation: Why Even the Best AI Struggles with Interruptions We’ve all been there. Mid-sentence, a friend chimes in, a question pops into your head, or a sudden noise distracts you. Human conversation is a messy, beautiful dance of interruptions, digressions, and overlapping speech. But for AI, even the most advanced conversational…
What the paper is really about Mathematicians love to think with pictures. The authors of this work, Jordi Delgado, Marco Linton, Jone Lopez de Gamiz Zearra, Mallika Roy, and Pascal Weil, bring that instinct to a very old idea in group theory: viewing complex algebraic objects as geometric or combinatorial gadgets you can twist, fold,…
Unraveling the Hidden Architecture of Family Networks Family is often described as the fundamental unit of society, a web of connections that shapes who we are and how we relate to the world. But beneath the surface of individual households lies a sprawling, intricate network of relationships stretching across generations. Understanding how this vast family…
When you ask a modern language model to solve a problem, you’re not just asking it for a number or a neat sentence. You’re inviting it to chain thoughts, weigh possibilities, and land on an answer that feels right. Yet the way the problem is framed—the style of reasoning you encourage the model to use—can…
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…
Space near the most extreme objects in the universe behaves like a carnival mirror: it twists light, stretches time, and turns simple paths into elaborate loops. Around massive, compact bodies, photons can get stuck in orbit, tracing circles that look almost musical in their precision. These light rings, or null circular geodesics, are more than…
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…
In the grand game of nuclei, protons and neutrons are players in a delicate dance. When two atomic nuclei collide at high speed, sometimes a proton—effectively a charged guest—gets traded or removed. The likelihood of that charge-changing event, called a charge-changing cross section (CCCS), carries the fingerprints of how protons are distributed inside the nucleus….
The study from Tuvi Etzion at the Technion introduces a new kind of combinatorial object—Steiner systems that ride on a mixed alphabet. Think of a code as a club sandwich of letters, with each column allowed to use a different bread—some slices may use size-2 alphabets, others size-5. And yet, the whole sandwich has a…
The Hidden World of Training Data Imagine building a house without ever inspecting the bricks. That’s essentially how we’ve been training large language models (LLMs) – relying on massive datasets without the tools to easily scrutinize their contents. These datasets are colossal, often encompassing hundreds of billions of words, and until now, researchers have lacked…
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…
Unveiling Hidden Order in Randomness: A Deep Dive into Young Tableaux Imagine a world built from LEGO bricks, but instead of simple squares, the bricks are shapes defined by mathematical objects called integer partitions. These partitions, represented visually as Young diagrams, form the building blocks of intricate structures. Now, picture these diagrams arranged randomly –…
Unlearning in plain sight: why forgetting matters in a world of image synthesis In an era when computers can conjure lifelike pictures from a few words, the power to forget specific ideas from these systems becomes not just a feature, but a moral responsibility. The study weaves a quieter kind of magic: it teaches a…
Curricula are more than a checklist of courses. They are living maps of how a university whispers from one topic to the next, from introductory ideas to the frontier edges of a discipline. A pair of researchers from Caltech and Georgia Tech have given us a new vocabulary for reading that map, revealing its shape…
Perfectly Balanced, Yet Mysteriously Unstable Imagine a perfectly balanced seesaw. It’s a picture of equilibrium, stability. Now, imagine that even the slightest nudge sends it crashing to one side, revealing a hidden instability. That, in essence, is the unexpected discovery at the heart of a recent paper from researchers at Nankai University, the University of…
In a square lattice built from tiny magnetic rods, light is not merely a wave; it’s a traveler navigating a city laid out by symmetry and magnetism. The traveler’s routes aren’t dictated only by the bulk of the material but by the way the city is cut and rearranged. A new study from Nanyang Technological…
In the hot, dense aftermath of heavy-ion collisions at the Large Hadron Collider, protons and neutrons melt into a foggy soup called the quark-gluon plasma. Inside this furnace, fast-moving quarks and gluons sprint through a medium that behaves like a near-perfect liquid, reshaping their journeys in ways that scientists are only beginning to decode. One…
A Universe of Voices: How One Observatory Is Tackling Language Barriers in Science The Vera C. Rubin Observatory, perched atop Cerro Pachón in Chile, is poised to revolutionize our understanding of the cosmos. Its colossal 8.4-meter Simonyi Survey Telescope and 3200-megapixel camera will map the southern sky with unprecedented detail, potentially uncovering billions of stars…
Imagine a world where elections perfectly reflect the will of the people, yet simultaneously protect the interests of even the smallest minority groups. This might sound utopian, but a new study from the University of Southern California, led by researchers Fatih Erdem Kizilkaya and David Kempe, delves into the surprisingly complex mathematics of achieving this…
