From heart to skin to hair, ‘Replaceable You’ dives into the science of transplant
From pig organs to 3D printing: The future of transplants – Science writer Mary Roach’s latest book, “Replaceable You: Adventures in Human Anatomy,” explores the history and future of replacing human body parts, from 16th-century prosthetic noses to modern advances in gene editing and 3D-printed tissue. Roach traces how pigs became the standard model for organ transplants, why genetic editing is crucial to reduce rejection and how scientists are working to print muscle that mimics natural structures.
