Five Planes Unveil Geometry’s Hidden Grammar.

Geometry sits at a peculiar crossroads. It houses the smooth continuity of lines and surfaces while also harboring a stubborn discrete side: how many ways can pieces intersect, split space, and create new regions? Stefan Forcey, at The University of Akron, leads us into that boundary in Counting Plane Arrangements via Oriented Matroids. The paper…

AI Predicts Chip Power Problems Faster Than Ever

The Power Struggle Within a Chip Modern computer chips are breathtakingly complex. Imagine a city crammed onto a surface smaller than a fingernail, with billions of microscopic transistors interacting in intricate patterns. These transistors need power, and distributing that power efficiently is a huge challenge. A critical problem is what engineers call “IR drop,” the…

The Binary Dance Behind the SMC’s Be Stars

Massive stars rarely lead solitary lives. In the Small Magellanic Cloud, a nearby dwarf galaxy with a tiny metal content, astronomers have a natural laboratory where stellar duets can be studied in exquisite detail. The environment’s metal paucity means winds are weaker and the life stories of giant stars are written in binary ink. A…

Is Speed in Graphs Always Worth Its Message Cost?

In the world of distributed computing, speed is measured in two ways that rarely line up perfectly: how many rounds of communication you need (time) and how many messages you churn through (the bill for bandwidth, energy, and processing). For decades, researchers have chased near-optimal time with clever protocols, then separately chased tight message budgets…

Two-Graph Insplitting Reveals Hidden Conjugacy in 2D Shifts

Two-dimensional shifts of finite type are like sprawling mosaics where each tile carries a rule about its neighbors. The math of these systems is famously slippery: local constraints produce global patterns, and two seemingly different viewpoints can describe the same dynamical universe in surprising ways. In a bold, multi-institution collaboration, Samantha Brooker, Priyanga Ganesan, Elizabeth…

LHC Detects a Hint of Something Unexpectedly Broad

A Glimmer in the Data The Large Hadron Collider (LHC) at CERN, that colossal atom-smasher buried beneath the Franco-Swiss border, has once again yielded intriguing results. A recent analysis by the CMS Collaboration, reinterpreting data from a previous search, hints at something unexpected: a broad resonance, a phenomenon that shakes up our understanding of particle…

Muons Take a Winter Turn in the Summer Sky

Seasonal Mystery of Muon Showers When the atmosphere hums with the heat of July, a quiet chorus travels underground: muons raining down from the sky, born in cosmic-ray showers high above. The NOvA Collaboration, working at Fermilab with researchers from around the world, has been watching a peculiar twist in that chorus. The rate at…

When Friends Vanish: Can AI Still Learn Together?

Imagine a group project where one member suddenly disappears, taking their notes and expertise with them. That’s the challenge facing decentralized federated learning (DFL) when a client drops out permanently. DFL is a cutting-edge AI technique where multiple devices (like smartphones or sensors) collaborate to train a machine learning model without sharing their raw data…
