How cats conquered the world

They often have a funny way of showing their affection, but domestic cats may owe their love of curling up on human laps to the ancient Egyptians.

A genetic study on feline remains dating back 9,000 years has revealed a lineage of cats from Egypt began spreading around the world around 3,000 years ago.

These creatures interbred with local animals and left distinct DNA that persist in our pets to this day.

The scientists behind the research believe the Egyptian cats were so successful because they had developed traits that made them better 'companions' than other types of wildcat.

Is Your Child Smarter than An Ape?

An experiment has revealed that most children surpass the intelligence levels of chimpanzees before they reach four years old.

The experiment, which was done by a group of researchers and led by Professor Thomas Suddendorf at, tested for foresight, which is said to distinguish humans from animals, according to Daily Mail.

The experiment saw researchers drop a grape through the top of a vertical plastic Y-tube.

The researchers then monitored the reactions of a child and chimpanzee in their efforts to grab the grape at the other end, before it hit the floor.

Secrets behind T. Rex's Bone Crushing Bites: T. Rex Could Crush with 8,000 Pound Bite Forces

The giant Tyrannosaurus rex pulverized bones by biting down with forces equaling the weight of three small cars while simultaneously generating world record tooth pressures, according to a new study by research team, according to Science daily.

In a study Professor of Biological Science Gregory Erickson and Paul Gignac, assistant professor of Anatomy and Vertebrate Paleontology, explain how T. rex could pulverize bones -- a capacity known as extreme osteophagy that is typically seen in living carnivorous mammals such as wolves and hyenas, but not reptiles whose teeth do not allow for chewing up bones.

The battle for nesting sites among the birds and the bees

Competition for nesting sites could explain why some birds and bumblebees are declining faster than others.

Research suggest animals that build their nests in early spring may win the fight for available habitat at the expense of late breeders, according to BBC.

Conservation efforts should focus on ensuring rare species have enough places to nest, say scientists.

For example, areas could be left to grow wild between spring and summer to help bumblebees establish nests.

Drug that creates a 'real sun-tan' could prevent cancer

Scientists have developed a drug that mimics sunlight to make the skin tan, with no damaging UV radiation involved.

The drug tricks the skin into producing the brown form of the pigment melanin in tests on skin samples and mice, according to BBC.

Evidence suggests it will work even on redheads, who normally just burn in the sun.
