Smartest bird to have ever lived
|
view preview
Bought from a pet shop, Alex the parrot was the subject of a 30-year experiment by psychologist Irene Pepperberg, who demonstrated that language, communication and intelligence are not just the result of a large primate brain; “lesser” animals also possess high cognitive ability. Alex could count, knew more than 100 words and even understood syntax. When he died, his last words to Pepperberg were: “You be good, see you tomorrow. I love you”

Ginger monkeys!

view preview
Some species of lutung monkeys from Southeast Asia are born with bright orange coats. Called natal coats, they're thought to have evolved to stop adult males killing young males. In a rare subspecies, the golden coat is sometimes retained into adulthood.

This fish looks like a melon
|
view preview
This is the red-eyed gaper, a type of anglerfish that can be found up to 2km below the ocean's surface. Its large head and red blobby face may not look too attractive, but the gaper lures prey in with the shiny patch between its eyes.

World's stinkiest plant
|
view preview
The three-metre-tall titan arum is one of the world’s stinkiest flowers. It smells like rotting flesh to attract flies and other insects which get stuck at the base and digested. It also only blooms for a few hours to a few days, so is often only seen in bloom in gardens rather than in the wild.

Would you eat this mysterious blue fish?
|
view preview
Lingcods are sometimes found with amazing, edible blue flesh. A bile pigment called biliverdin seems to be the cause, but exactly how it gets into the flesh of the fish remains a mystery.

Did you know that bees and flowers communicate using electric fields?
|
view preview
Researchers discover that bees and flowers communicate using electric fields. "It turns out flowers have a slight negative charge relative to the air around them. Bumblebees have a charge, too. The plant's electric field is changed by the proximity of that positively charged bee. And once the bee leaves, the field stays changed for 100 seconds or so. That's long enough for the altered field to serve as a warning for the next bee that buzzes by. She won't stop to investigate a flower that's already been visited." ...

Evolution is sneaky
|
view preview
While this little guy may look like some sort of 'Hummingbee' it's actually a Bee Fly. They sneak their eggs into beehives, where their larvae can parasitize bee larvae and eat their food reserves!

Does it rain in the Sun?
|
view preview
Physicists have figured out how colossal rainstorms are formed in the Sun's atmosphere, and it's surprisingly similar to how we get our rain. It turns out that plasma rain falls on the sun at 200 000 km/h. Each raindrop is the size of Ireland!

Beautiful double red rainbow
|
view preview
This double red rainbow was photographed over a Greek sunset by Manolis Thravalos. The optical phenomena is a result of Rayleigh scattering, which is the scattering of light by tiny particles in the atmosphere. This scattering is what causes the Sun to appear yellow and the sky to appear blue, and also results in red sunsets where the atmosphere is thicker around the horizon.
