| Nanoparticles can act like liquid on the outside, crystal on the inside Posted: 12 Oct 2014 10:49 AM PDT A surprising phenomenon has been found in metal nanoparticles: They appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal configuration.       |
| New records set for silicon quantum computing Posted: 12 Oct 2014 10:48 AM PDT Two research teams working in the same laboratories have found distinct solutions to a critical challenge that has held back the realization of super powerful quantum computers. The teams created two types of quantum bits, or "qubits" -- the building blocks for quantum computers -- that each process quantum data with an accuracy above 99%.  |
| Bioinspired coating for medical devices repels blood, bacteria Posted: 12 Oct 2014 10:48 AM PDT Medical devices implanted in the body or in contact with flowing blood present two critical, life-threatening challenges for doctors treating their patients: blood clotting and bacterial infection. A team of scientists and engineers has developed a new surface coating for medical devices using FDA-approved materials. The coating repelled blood from more than 20 medically relevant substrates the team tested -- made of plastic to glass and metal -- and also suppressed biofilm formation.  |
| Revving up fluorescence for superfast LEDs Posted: 12 Oct 2014 10:48 AM PDT Engineering researchers have made fluorescent molecules emit photons 1,000 times faster than normal -- a record in the field and an important step toward superfast light emitting diodes and quantum cryptography.  |
| A novel platform for future spintronic technologies Posted: 12 Oct 2014 10:48 AM PDT Spintronics is a new field of electronics, using electron spin rather than charge. Scientists have now shown that a conventional electrical insulator can be used as an optimal spintronic device.  |
| Detecting depressive states in elderly with on-line monitoring devices Posted: 09 Oct 2014 01:36 PM PDT Detecting depression in older adults through monitoring their daily routine has become a reality thanks to a new system developed by researchers. This technology can be used as an auxiliary tool for the care of elderly people, who for various reasons, such as family abandonment of or a chronic condition, tend to fall into a depressed state.  |
| Launch of new sensor device on Hudson River set to 'wire' river for cleaner water Posted: 09 Oct 2014 01:33 PM PDT In the race to find solutions to critical water issues, the launch of a new cost-effective water quality sensor device is the first step in overcoming hurdles of historically prohibitive costs for long-term water resource monitoring, scientists say.  |
| MRI machine provides in-depth analysis of strokes Posted: 09 Oct 2014 12:38 PM PDT A new, innovative way to classify the severity of a stroke, aid in diagnosis and evaluate potential treatments has been revealed by researchers. "Stroke affects millions of adults and children worldwide," said one expert. "This research offers a new technique for the chemical analysis of metabolites during stroke and a means of evaluating dynamic changes in cell processes and size in living tissue."  |
| Sculpting costumes with 3D printers is 'the way theater is headed,' say theater education experts Posted: 09 Oct 2014 12:38 PM PDT Three-dimensional printers, which already have churned out toys, prosthetic limbs and one functional car, are taking the stage — literally — in live theater. The new technology aids speed, creativity, flexibility — and can satisfy directors who change plans midstream, says a former Disneyland costume designer.  |
