Claude agents spotted a repeating DNA pattern beside a little-studied enzyme in viruses that infect bacteria. Researchers found related arrangements and measured short RNAs from the array. What the system does remains unknown.

Researchers fed measured results from laboratory-tested proteins back into a protein language model. Across five protein families, the approach generated candidates that performed better in the study's assays. This is a protein-engineering method, not evidence of a new medicine or benefit to patients.

AlphaFold 3 extends structure prediction beyond proteins to interactions involving DNA, RNA, small molecules and antibodies. Its benchmark gains can guide experiments, but a predicted structure is not proof of binding or biological effect.
