What do you get when you mix rigid and elastic polymers with a laser-scanning 3D printing technique? If you are researchers at ETH Zurich, you get robot hands with bones, ligaments, and tendons. In ...
Experts have been puzzled by recently discovered fossils from the hand of an extinct human relative, Paranthropus boisei. They have been surprised by a mix of human-like and gorilla-like traits in the ...
Measurement of hand bone mineral density (BMD) by use of digital X-ray radiogrammetry (DXR) could have a role in the assessment of localized bone loss as well as generalized osteoporosis, both of ...
