Elephants may never forget but now it seems they can now also grasp the need to co-operate. This palces them in an "elite group" of intelligent and socially complex animals.

Researchers from Cambridge University built apparatus originally designed to carry out the same experiment on chimps. The test consisted of two elephants having to work together, by each pulling a rope in order to tug a platform towrds them.

A new service to help tackle invasive pond species is being launched by Cornwall Wildlife Trust.

Pond Check aims to raise awareness of the threat of non-native plants that are invading Cornish ponds and waters.

The free service is targeting six of the most invasive aquatic plants including creeping water primrose, floating pennywort, parrot’s feather, New Zealand pygmy weed, large flowered water weed and the curly waterweed.
