| Under pressure, sodium, hydrogen could undergo a metamorphosis, emerging as superconductor Posted: 13 Jun 2011 01:22 PM PDT In the search for superconductors, finding ways to compress hydrogen into a metal has been a point of focus ever since scientists predicted many years ago that electricity would flow, uninhibited, through such a material.  |
| Faster computer graphics: Digitally mimicking photographic blur caused by moving objects Posted: 13 Jun 2011 08:38 AM PDT Researchers have developed new techniques for computing blur much more efficiently. The result could be more convincing video games and frames of digital video that take minutes rather than hours to render.  |
| Beam of X-ray laser light with shortest wavelength successfully produced Posted: 13 Jun 2011 02:38 AM PDT Researchers in Japan have successfully produced a beam of X-ray laser light with a wavelength of 1.2 Angstroms, the shortest ever measured. This record-breaking light opens a window into the structure of atoms and molecules at a level of detail never seen before.  |
| First telecommunications wavelength quantum dot laser grown on a silicon substrate Posted: 12 Jun 2011 10:41 PM PDT A new generation of high-speed, silicon-based information technology has been brought a step closer by researchers in the UK. The team's research provides the first demonstration of an electrically driven, quantum dot laser grown directly on a silicon substrate (Si) with a wavelength (1300-nm) suitable for use in telecommunications.  |
| Single GFP-expressing cell is basis of living laser device Posted: 12 Jun 2011 10:28 PM PDT Researchers have developed a device in which a single cell genetically engineered to express green fluorescent protein is used to amplify the light particles called photons into nanosecond-long pulses of laser light.  |
