A $2 portable HIV test chip that combines PCR-level sensitivity with home-test simplicity. Using magnetic microparticles, custom probes, and automated processing, it delivers rapid color-change results from a single drop of blood. The system could diagnose HIV and other viruses quickly, affordably, and anywhere.

This research introduces a computational method that detects up to one trillion RNA viruses hidden in standard RNA-sequencing data. By targeting protein signatures shared across all RNA viruses, the approach reveals viral RNA that previously went unnoticed. This enables large-scale viral discovery, tracking, and potential breakthroughs in understanding disease mechanisms.
