The formation of these tiny, fleeting objects at the LHC represents one way theorists have sought to resolve anomalies in our understanding of the basic structure of spacetime, while the method used to look for them demonstrates a new way of searching for new particles. https://phys.org/news/2026-09-physicists-quantum-black-holes-lhc.html General Physics Fri, 18 Sep 2026 14:20:07 EDT news708954181 One big dream of ultrafast science has been to watch changes in nanoparticles or biomolecules on their natural timescale. Experimentally, this can be realized by taking two snapshots of the same object only femtoseconds apart. However, no detector is fast enough to record the two snapshots separately—they end up on top of each other in a single image. https://phys.org/news/2026-09-ray-pulses-capture-nanoparticle-moments.html Nanophysics Mon, 07 Sep 2026 11:00:07 EDT news707992670 Physics is most readily applied to relatively simple systems: a pendulum, two electrons colliding or the structure of the solar system.

Traditionally, such entanglement has relied on active control and repeated measurements. Now, physicists at the Institute of Science and Technology Austria (ISTA) have realized a fully autonomous method for distributed entanglement using a "quantum bath" of correlated light particles. Published in Physical Review X, their work experimentally confirms a 20-year-old prediction and could provide a new platform for applied quantum technologies. https://phys.org/news/2026-07-physicists-year-theory-boost-quantum.html Quantum Physics Tue, 14 Jul 2026 10:40:04 EDT news703233448 As the global semiconductor industry enters the so-called 2-nanometer process era, the actual size of transistors—the core components of semiconductor chips—still remains above 10 nm. How much smaller, then, can transistors get?
