Anthropic says its Claude AI solved a nine-loop particle physics challenge, an extremely complex calculation in quantum field theory. Nine-loop computations involve vast numbers of terms and are traditionally done with specialized software and significant human effort, so a successful AI solution would mark a milestone for AI in theoretical physics. The claim is drawing attention from researchers assessing how far AI models can go in advanced scientific work.

Researchers at the University of Naples Federico II report that theoretical physics methods have helped reveal the molecular mechanisms governing extrachromosomal DNA in tumors. These circular DNA fragments, separate from chromosomes, are known to promote cancer growth and drug resistance. The study applies physical modelling to understand their behavior, potentially opening new avenues for cancer research and treatment strategies.
- 8AI computes record 9-loop physics amplitude▼AI beats human record, independently computes 9-loop physics amplitude | Most real-world calculations stop at 2, 3 loops | Inshorts
An AI system has reportedly set a record by independently computing a 9-loop physics amplitude, a Feynman diagram calculation far beyond typical human work. Most real-world perturbative calculations in quantum field theory stop at 2 or 3 loops due to their complexity. The result highlights how machine learning is beginning to automate some of the most demanding mathematical tasks in theoretical physics.

Claude, the AI assistant developed by Anthropic, is claimed to have beaten a record associated with physicist Lance Dixon by computing a nine-loop physics amplitude. The claim suggests a major step for artificial intelligence in theoretical physics, where multi-loop amplitudes describe particle interactions and are notoriously hard to calculate.
- 12Black Holes Might Shed 'Hair' and Turn Into Boson Stars●A Black Hole Could Spit Itself Out of Its Own Hair, Leaving a Boson Star in Its Wake https://www. sciencealert.com/a-bla
A new physics idea suggests a black hole could shed its 'hair' — the quantum properties that distinguish it — by ejecting them, transforming into a boson star in the process. The concept, reported by ScienceAlert, challenges the classic 'no-hair theorem' that black holes are defined only by mass, charge and spin. Science commentators are sharing the story widely, intrigued by its implications for black hole physics.

Physicists propose that under certain conditions a black hole could shed its 'hair' — quantum fields trapped around it — and transition into a boson star, an exotic object made of particles with no surface or event horizon. The idea, reported by ScienceAlert, touches on the 'no-hair theorem' and could offer new ways to test black hole physics through gravitational wave observations.
