A system of opposing genetic forces determines why mammals develop a single row of teeth, while sharks sport several, according to a study published today in the journal Science. When completely ...

Tooth analysis is often performed to study mammalian evolution and the adaptations that occur over the evolutionary timeframe. These adaptations, which are linked to genetic modifications, have ...

The U.S. National Institutes of Health National Institute of Dental and Craniofacial Research (NIDCR) has awarded a five-year, $2.3 million grant renewal to New York University (NYU) College of ...

Researchers at Eindhoven University of Technology for the first time have shown the earliest stages in biomineralization, the process that leads to the formation of bones, teeth and sea shells. They ...

As scarce as hen's teeth? Well, that depends. Researchers in Wisconsin discovered some years ago while working with a chicken embryo for another study that the bird had rudimentary teeth. They ...

Even with only jaws, Tanyka amnicola adds a new character to an ancient ecosystem that scientists are still trying to sketch ...

University scientists have identified a gene responsible for initiating the normal development of tooth roots in mammals. Researchers made this discovery by creating a mouse lacking the gene ...
