Antimicrobial peptides from the skin of frogs may protect against life-threatening, multidrug-resistant infections such as Pseudomonas aeruginosa, say researchers from Italy.

Using a moving 3-D computer model based on the skull and teeth of a New Zealand reptile called tuatara, researchers have revealed how damage to dental implants and jaw joints may be prevented by sophisticated interplay between our jaws, muscles and brain.

A researcher in Israel has developed an improved tool for translating lizard body lengths to weights. The new equations calculate this valuable morphological feature to estimate the weight of a lizard species in a variety of different ecosystems.
