Data shows no slowdown in global warming – 2014 hottest year on record

Contrary to recent reports that there has been a hiatus in global warming, with improvements in measurements scientists conclude that the rate of warming over the first 15 years of this century has, in fact, been as fast or faster than that seen over the last half of the 20th century. 2014 was the hottest year on record.

These sharks are known for their ability to make sudden and sharp turns as the unique wide-set placement of their eyes allows them a vertical 360-degree view, which is ideal for stalking their prey.

Coral reef fish ‘help protect jobs’

Jobs, ecotourism and diving industries can benefit from having a diverse supply of weed-eating fish on the world’s coral reefs, scientists say. Despite their small size, relative to the sharks and whales that often get more attention, herbivorous fish play a vital role in maintaining the health of coral reefs, which support the livelihoods of 500 million people worldwide, according to a study published this month in the journal Ecology.
A new study by researchers at the University of Cambridge has shown that the dottyback, a small predatory reef fish, can change the colour of its body to imitate a variety of other reef fish species, allowing the dottyback to sneak up undetected and eat their young. Its Latin name, Pseudochromis, means false damselfish - giving clue to its mimicry abilities.
