Computational biologists developed a simple way to test a language model’s understanding of proteins. The method holds potential to improve a range of language models in science.

Harvard researchers reveal the earliest known Chelicerata in a new study published in Nature. The 500-million-year-old fossil, named Megachelicerax cousteaui, provides unequivocal evidence of chelicera, a feature never before seen in Cambrian arthropods. The discovery pushes back the origin of chelicerates by at least 20 million years and proves their distinctive body plan emerged during the Cambrian explosion.

A review finds that antibiotic resistance genes—capable of undermining modern medicine—can travel through the air across both cities and farmland, and argues that airborne spread represents an overlooked public health risk.

At AACR 2026, Insilico will unveil four novel cancer inhibitors discovered via its end-to-end Pharma.AI platform. By harnessing trillions of data points and millions of molecular fragments, the platform integrates generative biology for target discovery with generative chemistry for de novo molecular design, accelerating the path from data to drug candidates.

Researchers at Aarhus University report a proof-of-concept DNA needle inspired by bacteriophages that can deliver molecules directly into cells and help them remain active. In laboratory experiments, the structure avoided endosomal trapping, a major limitation in current delivery methods. The approach may support future development of RNA-based therapies and treatments for rare genetic disorders.
