Scientists solve the mystery of how Botox attacks nerves and eliminates wrinkles
... authorities suspect was a cheap, non-FDA-approved imitation
of Botox. The botulinum toxin works by invading nerve cells, where it releases an enzyme that prevents muscle contraction. In recent years, scientists have determined that the enzyme binds to specific sites on proteins called SNAREs, which form a com...

Elephants imitate sounds as a form of social communication

to maintain individual-specific relationships, "study co-author Stephanie Watwood of WHOI said. "Our study suggests that elephants may be using their vocal learning abilities in a similar manner, and opens a fascinating new area for research on how e...

remains elusive in monkeys, this experiment found that monkeys recognise when they are being imitated. Ten pigtailed macaques were tested by two experimenters. One experimenter imitated the monkeys' actions with an object, the other performed tempora...
