Anthropic's Claude computes nine-loop quantum physics amplitude

New Capabilities

Home of Lance Dixon, who verified the nine-loop result

A small physics calculation just became a marker for AI capability. The six-particle scattering amplitude in planar N=4 super-Yang-Mills, a favorite testing ground for theorists, had sat at eight loops since 2023β€”until Anthropic's Claude pushed it to nine in late August 2026, running unsupervised for days at a cost of a few thousand dollars.

The race to practical superconductors

New Capabilities

Leading nickelate superconductor research

Scientists just cracked a problem that's plagued superconductor research for decades: how to make these wonder materials work without crushing them under diamond-anvil pressures. In February 2025, teams at SLAC and Stanford stabilized nickelate superconductors at everyday pressure using substrate compression, while University of Houston researchers locked in a superconducting state using a rapid pressure-release technique.

The Rubin Observatory opens its eye on 20 billion galaxies

New Capabilities

Completed LSST Camera construction

On June 23, 2025, the Vera C. Rubin Observatory released its first images. A 3.2-gigapixel camera, the largest ever built for astronomy, captured 10 million galaxies in a single frame. In just 10 hours of test observations, it found 2,104 asteroids nobody knew existed, including seven near-Earth objects; for the next decade, it will photograph the entire Southern Hemisphere sky every three nights.
