Functioning 'mechanical gears' seen in nature for the first time

a plant-hopping insect found in gardens across Europe - has hind-leg joints with curved cog-like strips of opposing 'teeth' that intermesh, rotating like mechanical gears to synchronise the animal's legs when it launches ...

Biological tools create nerve-like polymer network

Using a succession of biological mechanisms, Sandia National Laboratories researchers have created linkages of polymer nanotubes that resemble the structure of a nerve, with many out-thrust filaments poised to gather or send ...

Researchers generate electricity from viruses

Imagine charging your phone as you walk, thanks to a paper-thin generator embedded in the sole of your shoe. This futuristic scenario is now a little closer to reality. Scientists from the U.S. Department of Energy's Lawrence ...

Biologists create beetle with functional extra eye

On "Game of Thrones," a three-eyed raven holds the secrets of the past, present and future in a vast fantasy kingdom. But for real-world biologists, a "three-eyed beetle" may offer a true glimpse into the future of studying ...

Components based on nature's example

They are lightweight and yet strong and resilient: straw, bamboo, bones and teeth owe their surprising strength to their cleverly designed internal structures and a judicious combination of materials. The same principles ...
