Levent Alpöge, a mathematician who works at the artificial intelligence (AI) company Anthropic, casually announced on X ('hello there the jacobian conjecture is false thanx') that he had found a counterexample to the Jacobian conjecture, a very old and well-known problem in a field of mathematics called algebraic geometry. He had done this using Anthropic's large language model Claude Fable 5, released to the general public only a few weeks ago. https://phys.org/news/2026-07-tiny-social-media-mathematicians-rethinking.html Mathematics Wed, 22 Jul 2026 07:40:03 EDT news703918802 A new study led by MIT researchers could drive the development of more energy-efficient digital displays—such as flat-screen TVs, augmented and virtual reality headsets, smartphone screens, medical imaging devices and even large-area ambient lighting surfaces—that also generate richer, brighter colors. https://phys.org/news/2026-07-simple-solution-lifespan-quantum-dots.html Nanophysics Fri, 10 Jul 2026 14:00:06 EDT news702888058 Multiferroics are materials that exhibit more than one prominent "ferroic" property, such as ferromagnetism and ferroelectricity. One of their most advantageous features is that they allow engineers to control their magnetic states with electric fields or vice versa, due to an effect known as magnetoelectric coupling. https://phys.org/news/2026-06-interlayer-doping-room-temperature-multiferroics.html Condensed Matter Wed, 24 Jun 2026 08:40:01 EDT news701346383 A KAIST research team has succeeded, for the first time, in synthesizing the core raw material for fabricating asymmetric MXene, a so-called "Janus-faced" nanomaterial that can perform distinct functions because of differing atomic compositions on its two sides, paving the way for the development of multifunctional materials with applications such as removing radioactive pollutants and shielding electromagnetic waves. https://phys.org/news/2026-06-janus-nanomaterials-pave-capturing-radioactive.html Nanomaterials Thu, 11 Jun 2026 11:00:10 EDT news700391943 What if eyes could use light to heal themselves?

They crack differently than expected, or react in ways that are hard to explain. The answer often lies in their atomic structure. Is it neatly arranged, as in a crystal, or disordered, as in glass? Researchers at the University of Twente have now created a material that is both simultaneously. In two directions it is disordered; in the third, perfectly ordered. Their findings have been published in Nature Communications. https://phys.org/news/2026-03-chaos-layered-material-disorder-coexist.html Nanomaterials Mon, 23 Mar 2026 18:00:07 EDT news693489902 Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to encode signals or images. Yet controlling these properties independently remains difficult, especially when light can enter a device from either side. https://phys.org/news/2026-03-mbius-surface.html Optics & Photonics Wed, 04 Mar 2026 10:00:06 EST news691838582 In some solid materials under specific conditions, mutual Coulomb interactions shape electrons into many-body correlated states, such as Wigner crystals, which are essentially solids made of electrons. So far, the Wigner crystal state remains sensitive to various experimental perturbations.
