Surfer's ear points to ancient pearl divers in Panama

While examining a skull from an ancient burial ground in a pre-Columbian village in Panama, Nicole Smith-Guzmán, bioarchaeologist at the Smithsonian Tropical Research Institute (STRI), was surprised to discover an example ...

From receptor structure to new osteoporosis drugs

Biomechanics of chewing depend more on animal size, not diet

Chewing: We don't think about it, we just do it. But biologists don't know a lot about how chewing behavior leaves telltale signs on the underlying bones. To find out, researchers at the Jacobs School of Medicine and Biomedical ...
