Electrons in graphene can act like a perfect fluid, defying established physical laws. This finding advances both fundamental science and potential quantum technologies.
For decades, quantum physicists have wrestled with a fundamental question: can electrons flow like a flawless, resistance-free liquid governed by a universal quantum constant? Detecting this unusual state has proven nearly impossible in most materials, since atomic defects, impurities, and structural imperfections disrupt the effect.

Physicists have just made a new breakthrough in the enigmatic realm of time crystals.
For the first time, a time crystal has been built that can be directly seen by human eyes, rippling in an array of neon-hued stripes. The material’s construction could open up a whole new world of technological possibilities, including new anti-counterfeiting measures, random number generators, two-dimensional barcodes, and optical devices.
“They can be observed directly under a microscope and even, under special conditions, by the naked eye,” says physicist Hanqing Zhao of the University of Colorado Boulder.
A new supply chain attack on GitHub, dubbed ‘GhostAction,’ has compromised 3,325 secrets, including PyPI, npm, DockerHub, GitHub tokens, Cloudflare, and AWS keys.
The attack was discovered by GitGuardian researchers, who report that the first signs of compromise on one of the impacted projects, FastUUID, became evident on September 2, 2025.
The attack involved leveraging compromised maintainer accounts to perform commits that added a malicious GitHub Actions workflow file that triggers automatically on ‘push’ or manual dispatch.
