Researchers use hot nano-chisel to create artificial bones in a Petri dish

In research in the journal Advanced Functional Materials, a team at the NYU Tandon School of Engineering and New York Stem Cell Foundation Research Institute (NYSF) detail a system allowing them to sculpt, in a biocompatible material, the exact structure of the bone tissue, with features smaller than the size of a single protein -- a billion times smaller than a meter.
