Nature sometimes copies its own particularly successful developments. A team of scientists from the Max Planck Institute of Colloids and Interfaces in Potsdam and the Ben-Gurion University at Beer-Sheva in Israel has now found that the teeth of the Australian freshwater crayfish Cherax quadricarinatus are covered with an enamel amazingly similar to that of vertebrates. Both materials consist of calcium phosphate and are also very alike in terms of their microstructure. This extremely hard substance has apparently developed in freshwater crayfish independently from vertebrates, as it makes the teeth particularly strong.

A recent study published in the May/June 2012 issue of General Dentistry, the peer-reviewed clinical journal of the Academy of General Dentistry, found that an alarming increase in the consumption of sports and energy drinks, especially among adolescents, is causing irreversible damage to teeth—specifically, the high acidity levels in the drinks erode tooth enamel, the glossy outer layer of the tooth.
