| Rapid-scanning microscope with no loss of quality Posted: 24 Aug 2012 05:57 PM PDT Scientists have developed a rapid-scanning microscope with no loss of quality.  |
| Good diet, proper exercise help protect astronauts’ bones Posted: 24 Aug 2012 10:19 AM PDT Eating right and exercising hard in space helps protect International Space Station astronauts' bones, a finding that may help solve one of the key problems facing future explorers heading beyond low Earth orbit.  |
| Superior fuel cell material developed Posted: 24 Aug 2012 07:30 AM PDT Using a mixture of gold, copper and platinum nanoparticles, researchers have developed a more powerful and longer lasting fuel cell material.  |
| Flat lens offers a perfect image Posted: 24 Aug 2012 06:35 AM PDT Applied physicists have created an ultrathin, flat lens that focuses light without imparting the distortions of conventional lenses. It operates at telecom wavelengths -- i.e., those used for fiber-optics -- and is scalable to a wider range.  |
| Simplified approach for high-power, single-mode lasers Posted: 24 Aug 2012 06:35 AM PDT Researchers have developed a new resonator that creates the purest, brightest, and most powerful single-mode quantum cascade lasers yet at the eight-12 micron range, a wavelength of great interest for both military and industrial use.  |
| Posted: 24 Aug 2012 06:34 AM PDT A technique used by animators helps scientists model how cancer cells enter the bloodstream.  |
| Joining 'unjoinable' materials: New polymer linking technology based on nano crystals Posted: 24 Aug 2012 05:25 AM PDT Ever tried to paint on top of silicone? After a few hours, the paint will peel off. Annoying. Silicone is a so-called low surface energy polymer, well known from flexible baking forms: A synthetic material that has an extremely low adhesion or "stickiness." Teflon is similarly non-sticky and well known from frying pans. Researchers have now developed the first technology which is capable of joining these two "unjoinable" materials. The technology applies passive nano-scaled crystal linkers as internal staples.  |
| Virus detector harnesses ring of light in 'whispering gallery mode' Posted: 24 Aug 2012 05:19 AM PDT By affixing nanoscale gold spheres onto a microscopic bead of glass, researchers have created a super-sensor that can detect even single samples of the smallest known viruses. The sensor uses a peculiar behavior of light known as "whispering gallery mode," named after the famous circular gallery in St. Paul's Cathedral in London, where a whisper near the wall can be heard around the gallery.  |
