We thought it was evolution, but an experiment with pencils shows that tips like teeth and thorns may owe their rounded shape to mechanical wear. Most of us have been stung by a bee, bitten by an ...

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 ...

The animal kingdom is no stranger to astonishing abilities, including the remarkable power to regenerate lost or damaged body ...

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 ...

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 ...

Tooth root development relies on precise coordination of cellular signals, yet the underlying mechanisms remain unclear. Researchers have uncovered how two proteins, Gli2 and Gli3, work together to ...
