| New material puts a twist in light Posted: 18 Jul 2014 08:04 AM PDT Scientists have uncovered the secret to twisting light at will. It is the latest step in the development of photonics, the faster, more compact and less carbon-hungry successor to electronics. A random find in the washing basket led the team to create the latest in a new breed of materials known as metamaterials. These artificial materials show extraordinary properties quite unlike natural materials. |
| Revealed: The mystery behind starling flocks Posted: 18 Jul 2014 06:56 AM PDT The mystery behind the movements of flocking starlings could be explained by the areas of light and dark created as they fly, new research suggests. The research found that flocking starlings aim to maintain an optimum density at which they can gather data on their surroundings. This occurs when they can see light through the flock at many angles, a state known as marginal opacity. The subsequent pattern of light and dark, formed as the birds attempt to achieve the necessary density, is what provides vital information to individual birds within the flock. |
| 'Nanocamera' takes pictures at distances smaller than light's own wavelength Posted: 17 Jul 2014 03:05 PM PDT Researchers have demonstrated that an array of novel gold, pillar-bowtie nanoantennas can be used like traditional photographic film to record light for distances that are much smaller than the wavelength of light. A standard optical microscope acts as a 'nanocamera' whereas the pillar-bowtie nanoantennas are the analogous film. |
| Math can make the Internet 5-10 times faster Posted: 17 Jul 2014 06:48 AM PDT Mathematical equations can make Internet communication via computer, mobile phone or satellite many times faster and more secure than today. A new study uses a four minute long mobile video as an example. The method used by the Danish and US researchers in the study resulted in the video being downloaded five times faster than state of the art technology. The video also streamed without interruptions. In comparison, the original video got stuck 13 times along the way. |
