In-flight sensor tests a step toward structural health monitoring for safer flights Posted: 29 Sep 2014 09:39 AM PDT A flight test program is underway on nine commercial aircraft flying regular routes that are carrying sensors to monitor their structural health, alongside their routine maintenance. The flight tests are part of a Federal Aviation Administration certification process that will make the sensors widely available to U.S. airlines.

From diamonds to super computers Posted: 29 Sep 2014 08:45 AM PDT By exchanging specific atoms inside the mineral structure, quantum bits, required to process complex operations faster, could be stabilized.

Predicting landslides with light Posted: 29 Sep 2014 06:38 AM PDT A team of researchers in Italy are expanding the reach of optical fiber sensors 'to the hills' by embedding them in shallow trenches within slopes to detect and monitor both large landslides and slow slope movements.

'Autotune' software to make it quicker, easier and cheaper to model energy use of buildings Posted: 29 Sep 2014 06:37 AM PDT Building Energy Modeling uses computer simulations to estimate energy use and guide the design of new buildings as well as energy improvements to existing buildings.

Ultra-fast semiconductor nano-lasers turn on and off faster than any before Posted: 29 Sep 2014 06:03 AM PDT Physicist have develop ultra-fast semiconductor nano-lasers. One thousand billion operations per second – this peak value has now been achieved by semiconductor nano-lasers.

Mimicking brain cells to boost computer memory power Posted: 29 Sep 2014 06:03 AM PDT Researchers have brought ultra-fast, nano-scale data storage within striking reach, using technology that mimics the human brain. The researchers have built a novel nano-structure that offers a new platform for the development of highly stable and reliable nanoscale memory devices.

Predicting electric power outages before they happen Posted: 26 Sep 2014 06:35 PM PDT Power outages are often the result of automated protection measures that ensure power surges or downed power lines don't injure people, damage trees, damage appliances or impact other parts of the grid.

New tool assesses skill development in robotic microsurgery Posted: 26 Sep 2014 11:07 AM PDT A new standardized assessment provides a useful tool for tracking surgeons' progress as they develop the skills needed to perform robot-assisted microsurgery, reports a study.

High-throughput cell-sorting method can separate 10 billion bacterial cells in 30 minutes Posted: 26 Sep 2014 07:10 AM PDT A new, high-throughput method for sorting cells has been developed, capable of separating 10 billion bacterial cells in 30 minutes. The finding has already proven useful for studying bacterial cells and microalgae, and could one day have direct applications for biomedical research and environmental science -- basically any field in which a large quantity of microbial samples need to be processed.
