But a newly developed technique has found a way to bring them back to life in some cases. Researchers have now used the approach to resurrect the teeth and recognize the […]

Internal Bone Structure Reveals Loading and Walking Behavior

The form and structure of bones change as a result of the forces to which they are subjected. Researcher Patrik Christen of Eindhoven University of Technology (TU/e) has used this fact to determine the load using the bone structure. This knowledge can be important in predicting the progress and treatment of bone diseases, as well […]

Seelig created the fledgling enzyme […]
