Fermilab’s computing grid is more than a tech stack. It’s a living artery that pumps data, software, and collaboration across continents, fueling experiments that probe the mysteries of matter, energy, and the cosmos. For decades, the grid trusted users and machines through X.509 certificates—digital passports that could be shared and extended, but eventually grew unwieldy…
In 1945, the mathematician Paul Erdős nudged a seemingly simple geometric question into the spotlight: if you take n unit vectors in the plane and flip each one’s direction with a fair coin, how often does the resulting sum land inside the unit disk? It’s a question about randomness, balance, and how far a collection…
In the sprawling, unseen choreography of the Internet, traffic engineering is the conductor. It tries to route flows across a web of cables and satellites so that apps don’t stall, videos don’t freeze, and cloud services don’t grind to a halt. As networks grow from thousands to millions of links—think cloud WANs, data-center fabrics, and…
In the quiet back rooms of global health data, millions of adverse event reports flow in from clinics, labs, and public health campaigns around the world. Some describe the same patient, the same drug, and the same reaction, filed at different times by different reporters. Others are follow ups that should be linked, yet slip…
In the quiet borders of math and physics, scientists chase whispers of information that arrive through noise. Some whispers come from faraway echoes of a signal we can’t see directly, and the challenge is to reconstruct what happened from the clues left in a handful of measurements. That task is what mathematicians call an inverse…
Symmetry isn’t just about pretty patterns in wallpaper or snowflakes. In mathematics, symmetry is a precise language that encodes how many ways you can shuffle a system without changing its essential shape. The objects behind this language are called finite groups, and they come with a catalog of elements that behave in specific, rule-bound ways….
When we dream about machines that can read minds, the conversation often skims the surface of science fiction. Yet a new paper from an international team dares to step into that territory with unusual clarity and a wink of provocation. The authors claim to have built an AI that passes two classic tests of Theory…
The world of finite groups is the ultimate catalog of symmetry. Mathematicians crowd into it not with physical objects, but with abstract ideas: how objects can be rearranged, what counts as the same under a twist, and what hidden patterns emerge when you probe a group with its own representations. A character table is like…
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…
The Moon has long been a canvas for both hard science and human imagination. It is a place where the quiet arithmetic of rock, light, and gravity meets our stubborn urge to write stories about what we find there. In the past decade, advances in imaging and computation have started to tilt the balance toward…
On city streets where autonomous shuttles roam, a safety valve lurks behind the scenes: a human hand that can guide or override the machine from afar. The new paper from Technische Universität München sketches a blueprint for how a control center could orchestrate a fleet of automated vehicles on public roads, stitching together safety, regulation,…
In the quiet corners of mathematical physics, four-dimensional spaces can whisper secrets about how the universe might behave at its smallest scales. The paper by Lars Andersson and Bernardo Araneda—written from the vantage points of the Beijing Institute of Mathematical Sciences and Applications and the University of Edinburgh—takes a delicate, almost breath-like approach to those…
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…
On the desk of Keele University a lighthearted but surprisingly pointed paper proposes a single, sweeping idea: everything in the universe can be sorted into three buckets meat, vegetable and soup. The authors say they have built the most ambitious classification scheme yet, one that could cover both the planet and the cosmos, if you…
The night sky hides more than just stars. It hides a chorus of worlds orbiting those stars, some so close that their light can barely escape the star’s glare. For decades, astronomers have tried to tune that glare down without erasing the faint whispers of distant planets. Now a collaboration led by Yinzi Xin at…
In a world of rapid clips and clever edits, our brains read a scene not just from what happens, but from the sequence in which things unfold. A bottle opens, then it closes; a hand lifts, then it rests. The order matters. Machines, however, have often treated a video as a collage of stills, where…
The universe keeps a tempo, a distant drumbeat that grows louder when galaxies collide and their central black holes begin a slow waltz toward merger. For decades, scientists have listened with ground-based detectors to the aftershocks of stellar-mass black holes colliding in faraway corners of the cosmos. A different orchestra waits in the quiet, low-frequency…
Blood clots are not static sculptures; they are living, bending mechanical systems that must yield to the river of blood while resisting it. The scaffold of a clot is fibrin, built from the protein fibrinogen, which is transformed into a fibrous network when the body needs to stop bleeding. In a study from Bennett University…
In the quiet, humming world of quantum cryptography, the dream is simple: a group of people should share a secret that no one—not even a boundless computer—can crack. The physics of light and information promises that kind of security, but the real world isn’t perfectly quiet. Noise, lost signals, and finite data can turn a…
In the data-driven world, researchers want to learn from sensitive information without exposing the individuals behind the numbers. Differential privacy, a formal way to guard each person’s imprint, has long traded a bit of accuracy for a large shield of confidentiality. Yet as data grow in dimension and messiness—think dozens or hundreds of variables per…
