Stanford researchers used AI “digital twins” of pregnant women’s immune systems to identify two common drugs that may help prevent preterm birth

The SIMCO study was published in Science Advances on 2026-10-21 by Brice Gaudilliere's team. Reddit commenters questioned whether a true digital twin of a complex biological system is possible and whether causal claims hold.
