Bermuda land snail: An animal 'back from the dead'

The greater Bermuda land snail was thought to have disappeared for many years until an empty shell turned up in the territory's capital city, Hamilton.

Live snails were then found among litter in a nearby alleyway.

Some were flown to Chester Zoo for a unique breeding programme.

More than 4,000 snails raised at the zoo have now been taken back to the island and released.

Many more captive snails will soon be returned to their homeland to help give the species a new lease of life.

Chinese tombs yield earliest evidence of cannabis use

Researchers have uncovered the earliest known evidence of cannabis use, from tombs in western China.

The study suggests cannabis was being smoked at least 2,500 years ago, and that it may have been associated with ritual or religious activities.

Traces of the drug were identified in wooden burners from the burials, according to BBC.

The cannabis had high levels of the psychoactive compound THC, suggesting people at the time were well aware of its effects.

Fish become pessimistic and lovesick if they're torn apart from their true lover

Humans aren't the only species whose mental state is affected when they lose their lover, according to Daily Mail.

Female cichlids, a type of monogamous fish that primarily dwells in South America, become depressed and lovesick when their mate is removed and they're placed with a non-preferred male partner, a new study has found.

Researchers came to this conclusion after the female fish took longer to investigate boxes that either contained food or were empty, demonstrating symptoms of apathy.

Plant extinction 'bad news for all species'

The lost plants include the Chile sandalwood, which was exploited for essential oils, the banded trinity plant, which spent much of its life underground, and the pink-flowered St Helena olive tree.

The biggest losses are on islands and in the tropics, which are home to highly valued timber trees and tend to be particularly rich in plant diversity, according to BBC.

Scientists at the Royal Botanic Gardens, Kew, and Stockholm University found that 571 plant species had disappeared in the last two and a half centuries, a number that is more than twice the number of birds, mammals and amphibians recorded as extinct (a combined total of 217 species).
