Inside the Tylenol Pathway: An Interactive Lesson in Why Biology Is Hard

Tylenol is one of the most thoroughly mapped drugs in human biology. Watch the safe and toxic pathways branch, saturate, and fail — and see why AI drug discovery needs to see all of it at once.

Stack diagram showing the four layers AI drug discovery depends on: a data base layer of genomic, clinical, and experimental data; a pathway layer with cell-type-specific and time-resolved edges; a digital twins and simulation layer with virtual cells and organ-scale models; and AI drug discovery outcomes including target discovery, lead optimization, and in-silico Day Zero success. On the right, a multi-omic foundation model functions as an AlphaFold of pathway state.

The Pathway Layer: What AI Drug Discovery Needs to Build Next

AI drug discovery's biggest gap isn't models — it's pathway infrastructure. Six investments biology needs before AI can deliver on its promise.
