Scientists find two tiny new snails with shells that close like doors

A large Danish study found that children diagnosed with ADHD or autism today more closely resemble their peers in the general population than those diagnosed 10 years ago. The shift suggests that rising diagnosis rates may partly reflect broader identification and changing diagnostic patterns, rather than only an increase in the underlying conditions.

African elephants use dozens of different medicinal plants to treat themselves and their families when they are sick. This is the conclusion of a study which interviewed people who live and work alongside the elephants in the Mount Elgon region of Kenya. These particular animals have long intrigued scientists with their extraordinary behaviour - they are known as salt-mining elephants, because they go into caves and scrape the rock with their tusks to extract minerals for their diet.

Ariel, one of Uranus’ moons, may once have contained a subsurface ocean more than 100 miles deep beneath its fractured icy shell. The finding, combined with similar evidence from Miranda, suggests the distant Uranian system could harbor multiple hidden ocean worlds.

September's full Moon will rise across on Saturday 26 September. The best viewing conditions currently look to be across southern and eastern parts of the UK.
