Exact replicas of a man’s thumb bones have been made for the first time using a 3D printer. The breakthrough paves the way for surgeons to replace damaged or diseased bones with identical copies built from the patients’ own cells.
“In theory, you could do any bone,” says Christian Weinand of the Insel Hospital in Berne, Switzerland, head of the team that copied his thumb bones. “Now I can put spares in my pocket if I want,” he says.
I think survival is at stake for all of us all the time. It always has been individually, and now it has become demonstrably an issue that concerns all of us… I strongly feel that every poem, every work of art, everything that is well done, well made, well said, generously given, adds to our chances of survival by making the world and our lives more habitable.
