NEW TECH: How a ‘bio digital twin’ that helps stop fatal heart attacks could revolutionize medicine

Without much fanfare, digital twins have established themselves as key cogs of modern technology. A digital twin is a virtual duplicate of a physical entity or a process — created by extrapolating data collected from live settings. Digital twins enable simulations to be run without risking harm to the physical entity; they help inform efficiency gains made in factories and assure the reliability of jet engines, for instance.
