Researchers from the Nanophotonic Technology Centre (NTC) of the Polytechnic University of Valencia (UPV) have designed new silicon nanoantennas with direct applications in communication and data processing for the next generation of reconfigurable photonic chips.  Embeddable sensors record how and when neurons fire; electrodes spark heart cells to beat or brain cells to fire; neuron-like devices could even encourage faster regrowth after implantation in the brain.  Nanowires promise to make LEDs more colorful and solar cells more efficient, in addition to speeding up computers.  A new form of electron microscopy allows researchers to examine nanoscale tubular materials while they are "alive" and forming liquids-a first in the field.  A UCLA-led team has gained a never-before-seen view of nucleation-capturing how the atomsrearrange at 4-D atomic resolution (that is, in three dimensions of space and across time).  Self-assembly and crystallisation of nanoparticles (NPs) is generally a complex process, based on the evaporation or precipitation of NP-building blocks.  New nanoparticle-based films that are more than 80 times thinner than a human hair may help to fill this need by providing materials that can holographically archive more than 1000 times more data than a DVD in a 10-by-10-centimeter piece of film.  Researches of scientists from South Ural State University are implemented within this area.  Following three years of extensive research, Hebrew University of Jerusalem (HU) physicist Dr. Uriel Levy and his team have created technology that will enable computers and all optic communication devices to run 100 times faster through terahertz microchips.  When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution.  An exotic state of matter that is dazzling scientists with its electrical properties, can also exhibit unusual optical properties, as shown in a theoretical study by researchers at A*STAR.
