| Researchers test holographic technique for restoring vision Posted: 26 Feb 2013 10:42 AM PST Researchers are testing the power of holography to artificially stimulate cells in the eye, with hopes of developing a new strategy for bionic vision restoration. Computer-generated holography, they say, could be used in conjunction with a technique called optogenetics, which uses gene therapy to deliver light-sensitive proteins to damaged retinal nerve cells. In conditions such as retinitis pigmentosa (RP), these light-sensing cells degenerate and lead to blindness.  |
| Non-brittle glass possible: In probing mysteries of glass, researchers find a key to toughness Posted: 26 Feb 2013 08:40 AM PST Glass doesn't have to be brittle. Scientists propose a way of predicting whether a given glass will be brittle or ductile -- a property typically associated with metals like steel or aluminum -- and assert that any glass could have either quality.  |
| Connecting the (quantum) dots: First viable high-speed quantum computer moves closer Posted: 26 Feb 2013 08:40 AM PST Scientists have developed a new method that better preserves the units necessary to power lightning-fast electronics, known as qubits. Hole spins, rather than electron spins, can keep quantum bits in the same physical state up to 10 times longer than before, the report finds.  |
| Posted: 26 Feb 2013 08:38 AM PST Researchers have demonstrated a stretchable lithium-ion battery -- a flexible device capable of powering their innovative stretchable electronics. The battery can stretch up to 300 percent of its original size and still function -- even when stretched, folded, twisted and mounted on a human elbow. The battery enables true integration of electronics and power into a small, stretchable package that is wirelessly rechargeable.  |
| Infrared digital holography allows firefighters to see through flames, image moving people Posted: 26 Feb 2013 07:14 AM PST Firefighters now have a new tool that could help save lives. A team of researchers have developed a new technique using digital holography that can "see" people through intense flames -- the first time a holographic recording of a live person has been achieved while the body is moving. The new technique allows imaging through both.  |
| Newly observed properties of vacuums: Light particles illuminate the vacuum Posted: 26 Feb 2013 06:21 AM PST Researchers have succeeded in showing experimentally that vacuums have properties not previously observed. According to the laws of quantum mechanics, it is a state with abundant potentials. Vacuums contain momentarily appearing and disappearing virtual pairs, which can be converted into detectable light particles.  |
| Protecting fish from antidepressants by using new wastewater treatment technique Posted: 26 Feb 2013 05:11 AM PST Researchers have developed a new technique to prevent pharmaceutical residues from entering waterways and harming wildlife.  |
| Posted: 25 Feb 2013 06:22 AM PST Researchers have refined a method they previously developed for capturing and analyzing cancer cells that break away from patients' tumors and circulate in the blood. With the improvements to their device, which uses a Velcro-like nanoscale technology, they can now detect and isolate single cancer cells from patient blood samples for analysis.  |
