The Dictionary of Obscure Sorrows 'Nanocable' could be big boon for energy storage Thanks to a little serendipity, researchers at Rice University have created a tiny coaxial cable that is about a thousand times smaller than a human hair and has higher capacitance than previously reported microcapacitors. The nanocable, which is described this week in Nature Communications, was produced with techniques pioneered in the nascent graphene research field and could be used to build next-generation energy-storage systems. It could also find use in wiring up components of lab-on-a-chip processors, but its discovery is owed partly to chance. "We didn't expect to create this when we started," said study co-author Jun Lou, associate professor of mechanical engineering and materials science at Rice. "At the outset, we were just curious to see what would happen electrically and mechanically if we took small copper wires known as interconnects and covered them with a thin layer of carbon."

The Global Brain Institute The GBI uses scientific methods to better understand the global evolution towards ever-stronger connectivity between people, software and machines. By developing concrete models of this development, we can anticipate both its promises and its perils. That would help us to steer a course towards the best possible outcome for humanity. Objectives (for more details, check our strategic objectives and activities) Assumptions We see people, machines and software systems as agents that communicate via a complex network of communication links. Challenges that cannot be fully resolved by a single agent are propagated to other agents, along the links in the network. The propagation of challenges across the global network is a complex process of self-organization.

The Invisibility Cloak You've Been Waiting For Everyone from Harry Potter to working physicists are fascinated with cloaking devices. In science fiction, capes can make kids invisible, but in real life, scientists have only been able to hide certain wavelengths of light — and so far those have been in the part of the spectrum we can’t see. But now, researchers at at the University of Rochester have used simple, inexpensive, off-the-shelf components to hide objects in the visible spectrum of light. In other words, now you see it; now you don’t. When Will We Have Real Invisibility Cloaks? Such a system doesn’t work to fully hide you from the bad guys, but it could eliminate blind spots in vehicles or let surgeons see through their hands during delicate operations. The basic idea behind cloaking is to manipulate light waves, forcing them around an object, like sending river water around a stone. The video shows the effect. At the moment, the set up is not perfect. Top 10 Uses For Invisibility Tech via Phys.org Credit: J.

Lettre Édu_Num Langues vivantes N°25 — Langues vivantes Sommaire Cette lettre fait un zoom sur les dernières nouveautés de l'actualité du numérique pour l'enseignement.Elle propose pour se former au numérique des ressources (sites, applications ...) et des exemples d'usages sous forme de scénarios pédagogiques. La sélection des exemples d'usages du numérique provient essentiellement du résultat des travaux académiques mutualisés (TraAM) qui chaque année permettent à huit académies d'expérimenter et de rendre compte de pratiques pédagogiques utilisant les outils numériques.Elle vous tient informés sur les événements et l'actualité du numérique en général. Lors du salon Educatice a été inaugurée la nouvelle formule de la lettre d'information TIC'Édu qui devient désormais Édu_Num, avec un nouveau visuel. Parmi les objectifs de cette nouvelle version : l'intégration de plus de vidéos, de plus de contributions des académies et de lettres thématiques plus fréquentes. La première lettre Édu_Num a été publiée ce mois-ci.

Global Dynamics Processes: the Pattern which Connects from KaliYuga to Tao Antiláser Diseño[editar] Se disparan dos láseres idénticos, uno contra el otro, a través de un material absorbente de la luz, tal como el silicio. Este método sustituye el medio de ganancia de un láser con un material que presenta propiedades opuestas. El dispositivo enfoca dos rayos láser de una frecuencia dada en una cavidad en la que existe un material semiconductor, un disco de silicio que va alineando las ondas luminosas. Aplicaciones[editar] Entre los posibles usos que se podrían atribuir al antiláser se incluye la fabricación de interruptores ópticos para computadoras y equipos de transmisión eléctrica, a través de líneas de fibra óptica.[16] Véase también[editar] Láser Referencias[editar]

VHIL: Virtual Human Interaction Lab - Stanford University A 3D-printed running shoe that regenerates itself Running shoes are becoming increasingly sophisticated – but this one may well top them all. London-based designer Shamees Aden is developing a shoe that can be printed in 3D so that it fits a foot just like an extra layer of skin. The material used in printing the shoes is known as protocells. These are basic molecules which are not themselves alive but which can be combined to create living organisms. Aden is developing the shoe together with Dr Martin Hanczyc, an expert on protocell technology from the University of Southern Denmark. By mixing various types of these ’dead’ molecules, they will try to create materials that can be programmed to behave in different ways, depending on pressure, light and heat, thus providing extra cushioning if needed. Hanczyc explains the background of his protocell research in this TED talk. Shoe regenerates at night For the shoes to function optimally, they need to be soaked in a liquid protocell solution when not in use.
