3D printing used to replace woman's jaw
This is really cool. Doctors were able to create a titanium jaw using a 3d printer to replace a woman's infected one.
Ten-year-old Clara Lazen built a model of a never-before-seen molecule in a science class. Her teacher passed it along to a chemist at Humboldt State. It turns out to be similar to nitroglycerin, but with a different structure. Clara is a co-author on the paper.
Science depends on engineering
I touched on this concept in Is engineering science? Scientific progress is made possible through engineering advancements.
