Michael Polansky is training an AI model on skin that’s still alive
Not a celebrity vanity project. Michael Polansky is training AI on living human tissue to discover skincare compounds — a novel data source that could reshape how biotech validates molecules before human trials.

Why it matters
This represents a novel application of AI training on biological systems (living skin tissue as a data source for compound discovery), which is a frontier capability play in biotech AI. The ability to train models on live tissue rather than static datasets or animal models is a methodological breakthrough that practitioners in biotech and AI need to understand.
