Who needs supplements when you have kiwis?
|
view preview
Researchers from University of Otago have found that a natural fruit source of vitamin C – kiwifruit – is vastly superior to a purified supplement form. The researchers are studying kiwifruit as a source of dietary vitamin C and found that in mice eating kiwifruit, vitamin C uptake was five times as effective as taking a purified supplement form. The study was recently published in the American Journal of Clinical Nutrition, the highest ranking journal for human nutrition research. ...

Unusual defence mechanism
|
view preview
|
While the video may look like a trick an owner could teach their animal to do, some birds actually do play dead to avoid predation. If they feel in danger, they will essentially 'play dead' since predators are more interested in live, healthy prey than dead prey.

This is not an optical illusion
|
view preview
See anything peculiar? If you look closely, you'll see an Eastern screech owl hiding in plain sight. These owls are nocturnal and their amazing camouflage allows them to go largely unnoticed in the daytime. These owls only grow to about 22 cm (8.5 in) tall and weigh about 244 grams (8.6 oz), but they have been observed hunting squirrels and rats who rival them in length and weight. Eastern screech owls are found in North America from Canada all the way down to Mexico. ...

This fish looks like it can perform hypnosis
|
view preview
Stargazer fish have their eyes situated on the tops of their heads and can bury themselves in the sediment with only their faces sticking out. Some species lure prey with a worm-shaped projection that comes out of their mouths. They are toxic and some can deliver a 50 volt shock!

The Wobbegong shark
|
view preview
Not all sharks are built for speed. This bottom-dwelling wobbegong shark stays near the ocean floor. Its camouflage allows it to go largely unnoticed, until its prey wanders too close or thinks the tassels are something to eat. Then, the wobbegong leaps into action, devouring the unlucky fish, squid, or crustacean. They’ve even been seen swallowing other sharks whole!

The Bushveld rain frog
|
view preview
The Bushveld rain frog is found in Southern Africa. When threatened, it puffs itself up to ward off potential attackers. The frogs are sexually dimorphic, and the male is too small to mount the female properly to reproduce. The white secretion you see on the back of the frog is actually an adhesive that holds the male in place during copulation.

Ring trick
|
view preview
Belugas apparently fashion their own entertainment by creating bubble rings and then catching them. A beluga at Sea World Kamogawa, near Tokyo, was snapped in the act, and another at the Shimane Aquarium has been seen performing the trick.

Quench your thirst with tears
|
view preview
This pretty little moth from Madagascar, Hemiceratoides hieroglyphica, frequents birds at night and drinks their tears using a specialised harpoon-like proboscis. In the image, H. hieroglyphica prepares to drink tears from a sleeping common Newtonia ( Newtonia brunneicauda).

Personal drones – another step to absolute laziness
|
view preview
Engineers are building special drones that will deliver food to your table – or home. Besides the iTray, which brings customers sushi at a Japanese restaurant in London (above), researchers have developed a 'tacocopter' and 'pizzacopter' that can traverse six kilometers in ten minutes. But don’t get your hopes up yet, there are plenty of technological barriers to overcome before drones deliver pizzas to our homes.
