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.
