Ancient human ancestor Australopithecus sediba had unique diet: study
When it came to eating, an upright, 2-million-year-old African hominid had a diet unlike virtually all other known human ancestors, says a study led by the Max Planck Institute of Evolutionary Anthropology ...
Trapped dental 'calculus' holds clues to ancient human diets and health
Many ancient human teeth, including specimens tens of thousands of years old, still hold onto tiny pieces of food -- and even bacteria. Anthropologists are studying the tartar attached to ancient human teeth ...
Researcher cuts teeth in new method
University of Alberta researcher Nicole Burt took up an odd moonlighting job to further her research. She became a surrogate tooth fairy.
Under the microscope #15 - Elephant fish embryo
Dr Andrew Gillis shows us an embryonic skate head and explains how the red denticles dotted all over it have very similar properties to human teeth.
Nanocrystals make dentures shine
German chemists succeeded in producing a new kind of glass-ceramic with a nanocrystalline structure, which seems to be well suited to be used in dentistry due to their high strength and its optical characteristics. ...
Endangered orangutans offer a new evolutionary model for early humans
Starving orangutans in Borneo may be teaching us new lessons about human evolution.
New evidence for the earliest modern humans in Europe
