Many quantum effects can be observed only when a small number of particles is studied—individual atoms, molecules or photons, for example, carefully shielded from the rest of the world. But what about macroscopic objects, consisting of an unimaginably large number of particles? Can they, too, display effects that provide a direct glimpse into the quantum world? https://phys.org/news/2026-06-high-degree-quantum-entanglement-centimeter.html Condensed Matter Tue, 16 Jun 2026 17:00:04 EDT news700831442 A University of Melbourne researcher has placed the strongest constraints yet on certain rare decays of subatomic particles, narrowing the window for where new "hidden" particles could be lurking. https://phys.org/news/2026-06-rare-meson-decays-tighten-hidden.html General Physics Tue, 16 Jun 2026 15:40:04 EDT news700829881 Researchers around the world are racing to develop new quantum-based systems for sensing, communication, computing and control that have the promise of outperforming traditional systems.

How much smaller, then, can transistors get? KAIST researchers have developed a technology to predict that limit through quantum mechanical, atom-level calculations. https://phys.org/news/2026-06-atomic-simulations-transistor-scaling-limits.html Nanophysics Mon, 15 Jun 2026 10:00:05 EDT news700734001 Most people have seen nylon listed as a material on their clothing tags, but nylon is used in an array of other products, too, including automotive parts, wire insulation and medical supplies. Unfortunately, one of the building blocks of nylon, adipic acid, is produced from petroleum-derived benzene through energy-intensive processes and has a rather high carbon footprint. However, there may be a better way to produce this ubiquitous polymer. https://phys.org/news/2026-06-years-overlooked-material-poised-reshape.html Biochemistry Sun, 14 Jun 2026 12:40:01 EDT news700402907 Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, developed by Beichen Huang and colleagues at Tsinghua University and by Luca Toscani De Col and colleagues at the Vienna Center for Quantum Science and Technology in Austria, exploit the nucleus of a thorium-229 atom to keep time with extraordinary precision—possibly surpassing even the best atomic clocks available today. https://phys.org/news/2026-06-nuclear-clocks.html General Physics Fri, 12 Jun 2026 13:00:03 EDT news700484008 Birds in flocks, bacteria and cells: In many collective systems, individual elements respond to only part of their surroundings, seemingly defying Newton's third law of motion—action equals reaction. These exceptions are known as nonreciprocal interactions. A Dresden physics team working with Roderich Moessner, a founding member of the Würzburg–Dresden Cluster of Excellence ctd.qmat, has now developed a theory that makes it possible to describe these interactions efficiently and simulate them far more precisely. https://phys.org/news/2026-06-birds-newton-theory-sharpen-flocks.html General Physics Fri, 12 Jun 2026 10:20:07 EDT news700473061 Quantum materials, materials with properties that are governed by the laws of quantum mechanics, have proved to be highly promising for the development of ultra-efficient electronic devices, quantum processors, highly precise sensors and various other technologies.

When a very massive star has exhausted its nuclear fuel, radiation pressure can no longer provide sufficient counterforce to gravity. The star then collapses under its own mass until only a single point remains: the singularity. https://phys.org/news/2026-06-collapsing-stars-spawn-mini-universes.html General Physics Thu, 11 Jun 2026 15:20:04 EDT news700401421 Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which garnered a Nobel Prize in 1953, brought into clear view structures inside cells that had previously been too faint or washed out for biologists to study. https://phys.org/news/2026-06-physicists-phase-contrast-electron-microscopy.html Optics & Photonics Thu, 11 Jun 2026 14:00:06 EDT news700394697 Can networks of genes be stimulated using resonance? Researchers at the Niels Bohr Institute are investigating whether the protein p53, which activates a range of different genes, can be induced to communicate with the body's cells "on command."

Individuals with relatively little power possess a variety of behavioral strategies to counterbalance or regulate power differences. In humans, these strategies include criticism, ridicule, disobedience, or even the expulsion or execution of powerful individuals. Similar inequality-reducing behaviors, which carry comparable social costs, are also found in animal societies. https://phys.org/news/2026-06-animals-behaviors-alphas.html Plants & Animals Tue, 09 Jun 2026 15:00:01 EDT news700229941 Are two sets of data genuinely different, or is it because of randomness? This question, known as the two-sample testing problem, becomes notoriously difficult in modern datasets, because they are often high-dimensional, complex, and differences between them can take countless subtle forms. https://phys.org/news/2026-06-hidden-geometry-kernel-methods-complex.html Mathematics Mon, 08 Jun 2026 17:50:03 EDT news700156321 Superconductors, materials that conduct electricity with zero electrical resistance at specific temperature ranges, have proved very promising for the development of quantum computers and other cutting-edge technologies.

Einstein's theory of general relativity predicts that black holes obey a set of rules, known as the laws of black hole mechanics. These rules somewhat resemble the laws of thermodynamics, which delineate how energy, heat, and entropy behave in our universe. https://phys.org/news/2026-06-violating-3rd-law-black-hole.html General Physics Wed, 03 Jun 2026 07:00:04 EDT news699524996 MIT engineers are testing a new propulsion system that combines the power and speed of conventional chemical thrusters with the precision and fuel-efficiency of electrical thrusters.

The disk in question surrounds the young star AB Aurigae. Although it appears to generally rotate in accordance with the laws of physics, certain regions close to the star show an unexpected departure from this behavior.
