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.

Clever battery completes stretchable electronics package: Can stretch, twist and bend -- and return to normal shape 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.

'NanoVelcro' device to grab single cancer cells from blood: Improvement enables 'liquid biopsies' for metastatic melanoma 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.
