American Factories Lag in Adopting A.I. This Drugmaker Is an Exception.

In a sterile Bristol Myers Squibb lab about an hour north of Boston, scientists in scrubs and hairnets transfer living cells to a 2,000-liter stainless steel bioreactor that grows them for weeks. The goal is to produce proteins that are genetically engineered to attack cells that cause disease. Tiny variations in heat, light or pH level can stop the cells from growing, causing drug shortages that endanger patients. Typically scientists would have to wait to see what went wrong during that fragile process, but now artificial intelligence is used to…
