Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have determined the atomic-level structure of a zinc-transporter protein, a molecular machine that regulates levels ...

Teeth are composites of mineral and protein, with a bulk of bony dentin that is highly porous. This structure allows teeth to ...

Teeth may look simple on the outside, but inside they are complex structures made of minerals, proteins, and tiny channels ...

Advanced imaging revealed a sharp zinc increase toward the tooth pulp, tracking higher dentine porosity. The results could ...
