| 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. |
| Posted: 18 Jul 2014 06:57 AM PDT Twisting a screwdriver, removing a bottle cap, and peeling a banana are just a few simple tasks that are tricky to pull off single-handedly. Now a new wrist-mounted robot can provide a helping hand -- or rather, fingers. Researchers have developed a robot that enhances the grasping motion of the human hand. |
| '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. |
