How do tarantulas walk on walls?

It is a question scientists have long wanted to answer, why is it that large and heavy spiders like tarantulas are able to anchor themselves to slippery vertical surfaces without falling?

A team from Newcastle University have found the answer and the discovery helps explain how spiders first evolved their silk-spinning abilities.

Nature's Super Materials

In the pursuit of stronger, cleaner, and altogether better materials, scientists are turning to Mother Nature for inspiration. Biomimicry (literally "imitating life") is a field of science that studies naturally occurring processes and designs and looks for ways to mimic them. In this slide show, see some of the amazing structures and properties that animals and plants have evolved, and learn about new human-made super-materials they are giving rise to.

See some of Nature's stickiest, toughest, and cleanest materials, and learn how they are inspiring new products.

Bulletproof Skin??? Can we make a bulletproof human?

Scientists have created bulletproof skin by using spider silk... Actually, it's created using Spider Goats - goats that have genetically modified to have spider DNA in their milk. Believe it!

Researchers Create 'Bulletproof Skin'

Silk — one of the strongest natural materials known — has a long history of use in combat: Legend has it that Genghis Khan once issued tightly woven silk vests to his horsemen as protection against their enemies' arrows. Researchers have now taken silk one step further, and developed a fabric made of silk proteins that is strong enough to stop a bullet. Their ultimate goal: To give a person a layer of bulletproof skin. Here, a brief guide to this breakthrough:
