By simply casting a look towards our surroundings we can say that the amazing "inventions" of nature compete with the most advanced high technologies. The convergence between the living and the artificial world gave birth to an increasingly fecund science called bionics. This term was used for the first time by major... |

A squid is like a mass of gelatinous tissues. Still, its razor-sharp parrot-like beak is one of the toughest natural materials.

At a first glance, the association of the words "metal" and "rubber" seems to be at least illogical, if not absurd. The material properties of natural rubber that make it an elastomer and a thermoplastic are exactly the ones engineers try to avoid by using metal.But metal has one problem, that makes scientists turn... |

Would you feel confident to race against a Viper or a Corvette when you're in a 20-year-old pickup-truck? Probably not. But would you feel safer driving a 4.3 tons Hummer H1 truck on a busy highway? You surely would, don't even try denying it. I guess that's why the number of SUVs sold in the US is co... |

It may take as little as ten years for the airplanes on long, international flights to be made more out of plastic than metal. The most modern aircrafts of today are made of aluminum, a light but strong material than can be easily obtained from natural compound.The airliners of tomorrow will be made of advanced carb... |
