Scientists from Madagascar, the U.S. and Europe have described a new orchid species found up in the forest canopies of central Madagascar. The orchid, named Solenangis impraedicta, boasts a nectar spur that reaches 33 centimeters (13 inches) in length, making it the longest of any known plant relative to its flower size.

In 1862, when Charles Darwin was sent a specimen of orchid from Madagascar with its incredible nectar tube measuring a full 30 centimetres long, he exclaimed in a letter to a friend: 'Good heavens, what insect can suck it!'

Researchers have discovered that one population of white-faced capuchin monkeys in Panama have entered the Stone Age. The monkeys have started using stone tools to break nuts and shellfish, making them the fourth type of primates to do so after us.
