It was a pleasure to work with writer Andrea Teagle on this @knowablemag.bsky.social article about progress toward a functional cure for HIV. 🧪https://knowablemagazine.org/content/article/health-disease/2025/lasting-remission-hiv-with-broadly-neutralizing-antibodies
Achieving lasting remission for HIV
People infected with HIV must take antiretroviral drugs for life. But promising trials using engineered antibodies suggest that ‘functional cures’ may be in reach.

How a humble weed became a superstar of biology
Arabidopsis thaliana was always an unlikely candidate for the limelight. But 25 years ago, the diminutive thale cress launched the botanical world into the molecular era.
