These are the ultimate retro pants—and they are depicted to be 3,000 years old! They were found by archaeologists working at the Yanghai cemetery, in western China.

The two marmosets - small, New World monkeys - had been a closely bonded couple for more than three years. Then, one fateful day, the female had a terrible accident. Her partner left two of their infants alone in the tree and jumped down to apparently comfort and mourn her. Humans mourn their dead, of course, and some recent studies have strongly suggested that chimpanzees do as well. This new observation suggests that mourning is more widespread among primates than previously thought.

You see those embedded spirals of green, pink and blue? The green and blue spirals are actually the exact same colour.

When the green and pink colours are placed side-by-side, they enhance each other’s darker tones, making them look like completely new colours. How we perceive colours is dependant on the light and shadow surrounding them and on the placing of contrasting colours side by side.

This is what eyeball stitches look like after a cornea transplant. Beautiful and terrifying all at once.

The happiest animal in the world: The Quokka! It can be found on some smaller islands off the coast of Western Australia.

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." ...
