Chemist Lee Cronin is working on a 3D printer that, instead of objects, is able to print molecules. An exciting potential long-term application: printing your own medicine using chemical inks.
It’s relatively easy to imagine a new medicine, a better cure for some disease. The hard part, though, is testing it, and that can delay promising new cures for years. In this well-explained talk, Geraldine Hamilton shows how her lab creates organs and body parts on a chip, simple structures with all the pieces essential to testing new medications — even custom cures for one specific person.
Modern medicine is in danger of losing a powerful, old-fashioned tool: human touch. Physician and writer Abraham Verghese describes our strange new world where patients are merely data points, and calls for a return to the traditional one-on-one physical exam.
Maxillofacial surgeon Iain Hutchison works with people whose faces have been severely disfigured. By pushing to improve surgical techniques, he helps to improve their lives; and by commissioning their portraits, he celebrates their humanity. NOTE: This talk contains images of disfigured and badly injured faces that may be disturbing — and Hutchison provides thoughtful answers as to why a disfigured face can shock us so deeply. Squeamish? Hide your screen from 12:10 – 13:19, but do keep listening. Portraits shown in this talk come from Mark Gilbert.
What does it take to regrow bone in mass quantities? Typical bone regeneration — wherein bone is taken from a patient’s hip and grafted onto damaged bone elsewhere in the body — is limited and can cause great pain just a few years after operation. In an informative talk, Molly Stevens introduces a new stem cell application that harnesses bone’s innate ability to regenerate and produces vast quantities of bone tissue painlessly.
Tissue engineer and TED Fellow Nina Tandon is growing artificial hearts and bones. To do that, she needs new ways of caring for artificially grown cells — techniques she’s developed by the simple but powerful method of copying their natural environments.
