Short notes from across the sciences.

November 12, 2026 A research system using an unreleased Anthropic model has produced a proof of the Aaronson–Ambainis conjecture, concerning limits on quantum computational speedups. The proof has been checked using Lean, examined by independent mathematicians, and supplemented by alternative arguments. Its implications are substantial but specific Read more...
November 12, 2026 Mathematician Teng Zhang reports a proof of a conjecture posed in 1958 by Paul Erdős, Fritz Herzog, and George Piranian. The conjecture identifies which polynomial lemniscates have maximal length. The proposed solution combines complex analysis with rigorous computer- assisted estimates for finitely many degrees Read more...
November 12, 2026 Researchers at MIT and Northeastern University have developed metamaterials based on irregular, multiscale networks rather than repeating structural units. Experiments demonstrate improved impact absorption, distributed deformation, and adjustable stiffness. Published in Nature, the work suggests that carefully designed structural disorder can outperform conventional order Read more...
November 10, 2026 Anthropic reports that 1,000 cooperating Claude Fable 5.2 agents formalized Fermat's Last Theorem in thirty hours, with minimal human intervention. An earlier system required eleven days. The achievement suggests striking progress in automated mathematical formalization, although independent verification remains essential Read more...
November 10, 2026 Anthropic says the agents began with minimal prompts, developed their own coordination methods, and used a list of intermediate theorem statements rather than mathematical references. The resulting formalization reportedly required one-third as many computational action tokens as the earlier attempt and produced a proof seven times shorter. Read more...
November 9, 2026 After four decades of searching, CERN’s LHCb experiment has found evidence of an exceptionally rare particle decay, predicted to occur once in ten billion events. The result, statistically significant at 3.2 sigma, agrees with the Standard Model but requires further confirmation Read more...
November 9, 2026 An Anthropic study of 207,000 scientific AI sessions finds that researchers predominantly use language models for data analysis and writing, rather than generating hypotheses. Mathematics and computer science show particularly high adoption. The findings suggest a substantial gap between AI’s present uses and its scientific ambitions Read more...
November 5, 2026 Researchers at Anthropic have determined the three-dimensional structure of a previously uncharacterized vault-like protein particle produced in bacteria. Claude assisted with protein searches, experimental design, purification, and electron-microscopy analysis. The discovery may illuminate the evolutionary origins and still-mysterious functions of cellular vaults Read more...
November 5, 2026 OpenAI reports progress in using frontier models to design mechanical components, electronic circuits, and manufactured devices. A prototype incorporating AI-generated mechanical and electrical designs was manufactured, although production required human corrections. Industrial collaborations are exploring applications in automotive engineering and manufacturing Read more...
November 4, 2026 Researchers at CERN report evidence of a beauty meson decaying into two muons, an event predicted to occur roughly once in ten billion decays. The signal reaches 3.2 standard deviations, below the five-sigma discovery threshold. The result agrees with the Standard Model Read more...
November 4, 2026 Researchers introduce Strategist, an AI system that develops, tests, and reuses reasoning procedures across tasks. On thirty benchmarks, it reportedly outperforms the strongest baseline on twenty-four, achieving comparable average accuracy at 39 percent lower inference cost. Independent replication remains to be established Read more...
November 3, 2026 Physicists studying uranium ditelluride have discovered a previously hidden phase boundary that resolves an apparent violation of thermodynamics. Their measurements establish a tetracritical point and provide direct evidence that competing superconducting states can combine into a more complex form of superconductivity Read more...
November 3, 2026 Researchers at CERN report evidence of a rare decay in which a neutral beauty meson produces two muons. The signal, extracted from years of collision data, could eventually provide a sensitive test of particle physics beyond the Standard Model Read more...
November 2, 2026 A research-level mathematics challenge attracted 228 submissions comprising 4,802 pages of proofs and more than one million lines of code. Organizers report a complete formal proof of one open conjecture. Their AI-assisted evaluation system reduced false-positive judgments substantially Read more...
November 2, 2026 Using ultracold atoms in an optical lattice, physicists observed bound excitations moving coherently under conditions that immobilize individual particles. The experiment directly probes fracton-like behavior, in which conservation laws restrict motion but permit collective movement and scattering Read more...
