Most popular teen movies don’t reflect the true challenges of adolescence, suggests new research. Unlike a typical high school student, protagonists in movies, for example, are rarely shown to struggle with the physical aspects of puberty, and typically excel at initiating romantic relationships.

Only around 1% of turtles are affected by cancer – far less than in mammals or birds. Scientists have found the strongest evidence to date that cancer is extremely rare in turtles – which could help prevent and even fight the disease in humans.

In 2010, a female chimpanzee stuck a blade of grass in her ear and left it there, for no apparent reason. Others adopted the behaviour, and some chimps in the group still do it today. This shows that, like humans, other animals also copy seemingly pointless behaviours from one another.
