Bullying is not easy to define, namely because there is no one way to bully. It comes in many forms, from physical playground scuffles to verbal attacks. Even governments have a hard time defining it, often referred to as a repeated behaviour with the intent to hurt someone either physically or emotionally. By this definitions, there are many ape and monkey bullies, too. In fact, any hierarchical society is likely to have bullies in its midst.

An unfortunate monkey at the bottom of the hierarchy is repeatedly attacked and picked upon by those higher up in the group - they are sometimes beaten up every day. Bullying amongst rhesus macaques, for example, seems to release tensions among the higher-ups. Bullying seems to reinforce their bonds, a ...

Did you know one quart of horseshoe crab blood costs $15,000 dollars?

The critter's blue blood is a sort of bacteria killing machine that clots around ‘invaders’, eliminating them and protecting horseshoe crabs from lethal infections. Researchers have been harnessing the power of this blue blood to test medical supplies for contamination.

Birthmarks are congenital marks on the skin that appear at birth and occasionally disappears spontaneously. The term nevus refers to a benign cutaneous tumor consisting of blood capillaries. Such tumors, which rarely spread from their original site and are not dangerous, vary in color according to whether the capillaries composing them carry arterial or venous blood. The popularly termed cherry marks and port-wine stains (shown below) are nevi on a level with the surface of the skin. Certain other vascular nevi, commonly known as strawberry or raspberry marks (scientifically known as hemangiomas), are slightly elevated above the surface. These can appear anywhere on the body's surface, including the airway within the nose. The former Soviet ...

Even though being afraid of the dark sounds childish, our fear of the dark is an evolutionary trait that we picked up to survive real-life predators stalking the night. Researchers have hypothesised that this innate fear stems from a point of human history when we were nowhere near the top predators we are today. Humans only really became super predators with the advent of technology, which wasn’t that long ago.

Before technology, our ancestors were constantly on the look-out for predators that wanted nothing more than to chow down on human sandwiches. To make that even scarier, most of these predators hunted at night - a time of day when we are especially vulnerable to attack because of our relatively poor eyesight.  

This means that it was ...

Launched into orbit three years ago, a vial of Scotland's 'space whisky' is due home so researchers can see how the conditions in space affect flavour. This is one small step for man, one giant leap for whisky.

At first, it just looks like a worm. But when you peek closer, it slithers like a snake. It sticks its tongue out like a snake. It creeps you out like a snake.

Discovered under a rock in 2006 in Barbados, this thread snake is as thin as spaghetti and smaller than any of the 3,100 other known snake species. Researchers believe it is the smallest a snake can evolve to be.

As its scientific name suggests, the Antilles pinktoe tarantula (Avicularia versicolor) changes color as it matures. The spider’s abdomen turns from blue to pink or red and the carapace becomes metallic green.

Antilles pinktoe tarantulas are native to Guadeloupe, Dominica and Martinique in the Caribbean Sea. They are arboreal (tree-dwelling) species, and can spin elaborate funnel webs in which they spend most of their time. Though these tarantulas are naturally docile, they are quick and can jump up to 30 cm far or high! ...
