So you can only imagine their delight, when they stumbled upon an unexpected treasure trove of perfectly preserved shipwrecks, many of which are known from historical sources, but have never been seen before....

While parrots are usually credited as the avian world’s best mimickers, the title probably belongs to the aptly named superb lyrebirds. Endemic to Australia, the ground birds are extremely shy and difficult to approach. Hence, though researchers have known of their ability to imitate everything, from other birds, to humans, and even car alarms and chainsaws, very little was known about their lifestyle in the wild. Now thanks to a team of researchers led by Dr. Anastasia Dalziell, a Postdoctoral Associate at the Cornell Lab of Ornithology, we finally have some insight into these amazing ancient animals that have been around for millions of years....

Researchers had long known that Aboriginal Australians once used boomerangs for hunting and digging. Now, a new study suggests that the natives created ‘killer’ versions of the iconic Australian souvenirs to fight internal battles as well....

Coral reefs are one of the most diverse and important ecosystems on Earth. Not only do they provide food and habitats for the fish and seafood we eat, but they also shelter many other organisms that are crucial for ocean food chains. Experts estimate they contribute about $30 billion USD to the global economy annually, through tourism, fisheries, and coastal protection. Unfortunately, warming ocean waters, acidification, and over-fishing are killing the beautiful reefs at unprecedented levels....

Listen up Potterheads! Muggle student scientists from the U.K.’s University of Leicester have been researching some critical matters: do the spells and potions that Harry Potter and his fellow wizards use really need magic to work or do they have a scientific basis?
