At a blistering 1.125 terabytes per second, a new optical communication system developed by University College London (UCL) researchers has created a new
record for the fastest ever data transfer rate for digital information. At the quoted rate, say the researchers, the entire HD series of the TV show Game of Thrones could be downloaded in less than one second.
Researchers from Vanderbilt University in Nashville, Tennessee have created the world's smallest continuous spirals. Made from gold, the spirals exhibit a set of very specific optical properties that would be difficult to fake, making them ideal for use in identity cards or other items where authenticity is paramount.
Using visible light magnified through a compound series of lenses to image small objects, standard optical microscopes have been with us for many centuries. Whilst continually being improved, the result of these many advances of optics and image-capturing techniques means that many high-end optical microscopes have now reached the limit of magnification possible as they push the resolution properties of light itself. In an attempt to resolve this issue, scientists at the University of Buffalo (UB) have created a prototype visible light "hyperlens" that may help image objects once only clearly viewable through electron microscopes.
