The quest to unify gravity with quantum mechanics—a holy grail of theoretical physics—has led researchers down many winding paths. One promising avenue is asymptotic safety, a concept suggesting that quantum gravity, rather than collapsing into an intractable mess of infinities at high energies, reaches a stable fixed point, much like a ball settling at the…
Chasing Numbers with a Greedy Heart At first glance, the idea seems simple: take a number you want to approximate, and build it up step by step by adding or subtracting fractions—like 1/1, 1/2, 1/3, and so on—choosing at each step whether to add or subtract to get closer to your target. This process, known…
Tracing the Invisible with Cosmic Tidal Streams Galaxies are not isolated islands but dynamic cities shaped by cosmic collisions and mergers. When a small galaxy ventures too close to a larger one, gravity tears it apart, leaving behind delicate stellar streams—ghostly rivers of stars arcing through space. These streams are more than just beautiful remnants;…
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,…
Imagine trying to understand a movie by only looking at the visuals, with the sound muted. You’d miss crucial information – the dialogue, the music, the subtle sound effects that set the scene. That’s the challenge AI faces when trying to understand videos, and why researchers are working to give it a better sense of…
The Perils of AI in Healthcare: A Story of Biased Ears Artificial intelligence is poised to revolutionize healthcare, promising faster diagnoses, personalized treatments, and more efficient workflows. But a new study from researchers at Microsoft’s AI for Good Lab, the University of Sydney, and other institutions, led by Yixi Xu and Al-Rahim Habib, throws a…
The internet age has unleashed a torrent of easily copied multimedia content – videos, music, images – making copyright protection a constant battle. One clever technique used to fight piracy is multimedia fingerprinting: embedding unique identifiers into each copy of a digital work. If a pirated copy shows up, these fingerprints can theoretically trace it…
Every morning in modern cities a quiet battle unfolds on asphalt and in dashboards. Packages queued in warehouses become delicate tradeoffs of timing, routes, and human judgement as couriers weave through traffic, weather, and roadwork. The math behind that everyday drama is invisible to most of us, but it is the heartbeat of same day…
Imagine the world’s most stressful game of Tetris, but with multi-million dollar airplanes instead of colorful blocks. That’s the daily reality inside aircraft maintenance, repair, and overhaul (MRO) hangars, where optimizing space and time is the difference between profitability and gridlock. Every minute an aircraft spends waiting for maintenance is a minute it’s not generating…
Defect prediction gets a human face For decades, people have tried to forecast where software bugs will hide, usually by scanning code for telling fingerprints—the code metrics, churn rates, commit histories. The new work from researchers at the University of Tsukuba shifts the lens. Instead of treating defects as purely a code problem, they ask…
The Untapped Potential of African Languages Africa, a continent pulsating with a vibrant tapestry of over 2,300 languages, has largely remained unheard in the digital world. Speech technology—the ability of computers to understand and generate human speech—has primarily focused on a handful of dominant languages, leaving a vast linguistic landscape unexplored. This digital silence excludes…
The universe keeps a few stubborn secrets in its pocket: the densest matter, the fastest spins, and the kind of energy that can light up entire galaxies for a moment in time. Neutron stars sit right at the crossroads of all three. They’re city-sized bundles of neutrons packed so tightly that a sugar-cube amount would…
Graphs are the hidden streets of modern AI: social networks where friends connect, citation maps where topics cross-pollinate, product graphs where shoppers discover new things. In these networks, the challenge isn’t just to classify a node, but to tell when a node doesn’t fit the pattern of anything the system has seen before. That’s the…
In the world of drone racing, machines zipp through a gauntlet of gates at breakneck speeds, while human pilots read the air with instinct and nerve. A new study from Delft University of Technology asks a bigger question: could a single neural controller drive different drones as if it shared one brain across a family…
Demokritos National Research Center in Athens, Greece, home to the Institute of Nuclear and Particle Physics, is where George Savvidy and colleagues push the boundaries of how we describe massless particles. In a study threaded through the language of non-commutative geometry and deep symmetry, the author explores how photons and gravitons—the massless quanta of light…
Black holes: cosmic vacuum cleaners, or something far stranger? For decades, physicists have wrestled with the implications of these gravitational behemoths, especially when quantum mechanics enters the picture. The late Stephen Hawking famously predicted that black holes aren’t truly black but emit radiation, leading to their eventual evaporation. But this raises a thorny problem: what…
Imagine a world where robots don’t just assemble your gadgets, but also obsessively check their own work, catching tiny defects before they become big problems. That’s the promise of a new AI system called Self-Navigated Residual Mamba (SNARM), developed by researchers at Jiangxi Normal University and several other institutions. The Problem: Spotting Tiny Flaws in…
The world of quantum gases hides a strange landscape called flat bands, where an astonishing number of quantum states share the same energy. In that flat-energy terrain, even tiny interactions can tilt reality in surprising ways, turning a seemingly inert system into a stage for dramatic collective motion. A new paper led by Yi-Cai Zhang…
Imagine a world where controlling complex systems, from power grids to swarms of robots, becomes simpler and more efficient. This isn’t science fiction; it’s the promise of a new approach to control theory emerging from research at The Hong Kong Polytechnic University and Nankai University. Led by Lechen Feng, Xun Li, and Yuan-Hua Ni, their…
The Rise of the Robotic Interviewer Imagine a world where surveys are conducted not by humans, but by AI. This isn’t science fiction anymore. Researchers at VKL Research, Inc., in collaboration with SSRS, have developed an AI system capable of conducting complex, quantitative telephone surveys. Their work, recently presented at the 2025 American Association of…
