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.

One fifth of the US prison population are former foster children, raising questions of a causal relationship. Quasi-randomization (similar children that were either placed or not placed in foster care) indicates that being placed in foster care actually reduces future incarceration.
