The study of protein structures is a very complex and delicate one, focusing on tiny formations at a very small scale. But this field of research could soon benefit from a large push forward, as researchers recently announced the development of a new laser technology, which allows the use of light pulses to grow High... |

The RepRap project managed to give birth to something that you might call a printer only if you think outside the box. The RepRap (Replicating Rapid-prototyper) device is able to replicate and update itself whenever it is necessary. In order to update itself, the unit prints its own parts.According to software develo... |

A squid is like a mass of gelatinous tissues. Still, its razor-sharp parrot-like beak is one of the toughest natural materials. The beak of a jumbo squid can sever the nerve cord of a large fish, paralyzing it, and they can do this to divers as well. But each time they bite, powerful forces exert pressure on the soft... |

Only one thing comes to my mind when talking about carbon nanotube electrical properties, conductive transparent polymer plastics, which pretty much have a wide range of applications, especially in the manufacturing process of solar cells. It seems that the conductivity of a carbon nanotube additive can be changed re... |

Carbon nanotubes have been considered for some time now the perfect building blocks for the future generation of ultrafast computers, but working with such small structures is no easy task, especially while trying to line them up into a specific architecture. This wouldn't be so big a deal, however it disables t... |

Science fiction materials have turned real. Steel strong plastic has been created by a team at the University of Michigan by imitating the brick-and-mortar molecular structure of the seashells. But unlike steel, the new material is lighter and transparent, even if not stretchy enough. The new plastic is built of lay... |

People spend annually $10 billion for chewing gum, but this leaves a sticky mess all around us, which is everywhere: from streets to cinema seats. And removing discarded gum is also an industry of millions of dollars. Now, a British company has announced the development of an easy-to-remove chewing gum. The team at t... |

Imagine a piece of paper that would move and have the shape of a fish. A Harvard team led by biomedical engineer Kit Parker has developed thin sheets of elastic film studded with rat heart muscle cells that can turn this into reality. The muscle-bound sheets react to electricity, as muscles contract, bend and flex th... |

A surgery can be performed very well, but one of the most dangerous side effects are infections. Only in US, each year 2 million people get infected while in the hospital and over 90,000 die. This number is much higher in developing countries, with less technology and less hygienic conditions. Penicillin could be emp... |

Harvesting solar energy is a clever way to make use of a clean and renewable fuel. You don't need to dig the ground for it, there are no pipes and powerplants, and best of all, it's ecological. Unfortunately, existent solar cells are not too efficient and often too expensive.A new development made by resea... |
