An AI wrote 16 working viruses: a genome model trained on DNA from across the tree of life designed new bacteriophages, and 16 of the roughly 300 built in the lab infected E. coli. A mix of them cleared antibiotic-resistant strains that natural phages could not. (CNN)
Uber open-sourced the security layer for its coding agents: ADR watches what Cursor, Claude Code and five other agent platforms actually do on employee machines, then triages sessions for suspicious behaviour. It ships with a benchmark of 300-plus tasks and 133 MCP servers covering all 17 known agent attack techniques. (GitHub)
Replit's engineers ship 5.8 times more code each: Amjad Masad says lines contributed per engineer rose that much in six months without quality slipping, and an internal bot now answers business questions off Notion, Postgres and the codebase. He cancelled most of the company's analytics vendors after rebuilding them in-house. (Platformer)
