At first sight, it looked like a crime place. A drought cadaver was lying face downward, half stuck in the ice. An accidental death or a crime? Or just another mountaineering victim at 3,200 m (10,660 ft) height in the Tirol Alps? The Ice Man was found in September 1991 by casualty by a couple of German mountaineers ... |

Graphene is a one-atom-thick sheet of carbon and was really hard to separate from graphite in a laboratory until 2004, when researchers used nothing more than clear adhesive tape to break apart the countless layers of graphene from an everyday pencil. Rensselaer Polytechnic Institute's Department of Physics, App... |

The design of the electric motor, which converts electrical energy into mechanical energy, hasn't changed much since it was invented, some 50 years ago. New technological developments in the field of superconductors are about to change that.El Hadj Ailam and colleagues working at the Université Henri Poincaré i... |

A natural fabric is impossible to be preserved: being organic, in just a few years at most, bacteria decompose the material. In fact, all that is organic (wood, leather, paper) is out of archaeologists' reach. That's why Greek archaeologists were very surprised to discover a rare 2,700-year-old piece of f... |

When Columbus made his first steps on the American ground (or better said, Caribbean), his mind was set on an El Dorado, a realm of gold and silver riches. And indeed, they soon discovered two El Dorados: the Inca and the Aztec Empires. In 1532, Incas paid to Pizzaro, the conquistador of their empire, a ransom consi... |

The crockery was the first technological process through which people handled high temperatures and complicate chemical reactions of oxidation and reduction. 8,000 years ago, European populations were using malachite (a copper oxide) to get colorants. Perhaps ancient people noticed the transformations suffered by thi... |
