Stitched for strength: The physics of jamming in stiff, knitted fabrics

School of Physics Associate Professor Elisabetta Matsumoto is unearthing the secrets of the centuries-old practice of knitting through experiments, models, and simulations. Her goal? Leveraging knitting for breakthroughs in advanced manufacturing—including more sustainable textiles, wearable electronics, and soft robotics.

Matsumoto, who is also a principal investigator at the International Institute for Sustainability with Knotted Chiral Meta Matter (WPI-SKCM2) at Hiroshima University, is the corresponding author on a new study exploring the physics of ‘’—a phenomenon when soft or stretchy materials become rigid under low stress but soften under higher tension.

The study, “Pulling Apart the Mechanisms That Lead to Jammed Knitted Fabrics,” is published in Physical Review E, and also includes Georgia Tech Matsumoto Group graduate students Sarah Gonzalez and Alexander Cachine in addition to former postdoctoral fellow Michael Dimitriyev, who is now an assistant professor at Texas A&M University.

Compact setup successfully detects elusive antineutrinos from nuclear reactor

Neutrinos are extremely elusive elementary particles. Day and night, 60 billion of them stream from the sun through every square centimeter of Earth every second, which is transparent to them. After the first theoretical prediction of their existence, decades passed before they were actually detected. These experiments are usually extremely large to account for the very weak interaction of neutrinos with matter.

Scientists at the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg have now succeeded in detecting antineutrinos from the reactor of a using the CONUS+ experiment, with a detector mass of just 3 kg. The work is published in Nature.

Originally based at the Brokdorf nuclear power plant, the CONUS experiment was relocated to the Leibstadt nuclear power plant (KKL) in Switzerland in the summer of 2023. Improvements to the 1 kg germanium semiconductor detectors, as well as the excellent measurement conditions at KKL, made it possible for the first time to measure what is known as Coherent Elastic Neutrino-Nucleus Scattering (CEvNS).

This One Sleep Habit Could Be Secretly Wrecking Your Health

New research reveals that irregular sleep patterns, not just how long we sleep, may significantly raise the risk of numerous diseases. A major international study published in Health Data Science has revealed strong links between sleep patterns and the development of 172 different diseases. By ex

Columbia Engineers Develop Radiation-Hardened Chips for the Large Hadron Collider

In one of the most extreme environments on Earth—the Large Hadron Collider—normal electronics fail almost instantly. But engineers at Columbia University have created custom microchips that not only survive the collider’s intense radiation but play a pivotal role in unlocking the secrets of the univ

Astronomers Finally Crack the Mystery of Cosmic X-Ray Blasts

The mysterious cosmic explosion has been traced to a massive stellar explosion. A global team of astrophysicists, led by researchers from Northwestern University and the University of Leicester (England), may have identified the origin of fast X-ray transients (FXTs), mysterious, fleeting bursts of
