Forces that hold rapidly spinning near-Earth asteroid together discovered Posted: 13 Aug 2014 10:20 AM PDT Astronomers studied near-Earth asteroid 1950 DA and discovered that the body, which rotates extremely quickly, is held together by cohesive forces called van der Waals, never detected before on an asteroid.

Gearing up to keep women from fleeing IT profession Posted: 13 Aug 2014 10:09 AM PDT A new article shows employers and experts where to invest resources to reverse the exodus of women from the IT workforce. Studies show that women are significantly underrepresented in the IT field, and the number of women who've graduated with degrees in computer and information science have plummeted from 37 percent in 1985 to 18 percent in 2011. The failure to "stop the bleeding" stems, in part, from the industry's reliance on an oft-cited, outdated and under-studied research model, said one expert.

3-D microscope method to look inside brains Posted: 13 Aug 2014 10:00 AM PDT A method for turning a small, $40 needle into a 3-D microscope capable of taking images up to 70 times smaller than the width of a human hair has been developed by scientists. the microscope technique works when an LED light is illuminated and guided through a fiberoptic needle or cannula. Returned pictures are reconstructed into 3-D images using algorithms.

Embedded wireless motion detector device on conventional insect trap for analysis purpose Posted: 12 Aug 2014 08:51 PM PDT Researchers have developed a prototype insect trap that utilizes motion sensor and wireless technology to detect insect and transmit data to the researcher at the base station located away from the study area.

Foam favorable for oil extraction: Experiments visualize methods for enhanced recovery from wells Posted: 12 Aug 2014 01:38 PM PDT Researchers demonstrate that foam may be a superior fluid to displace and extract tough-to-reach oil. In tests, foam pumped into an experimental rig that mimicked the flow paths deep underground proved better at removing oil from formations with low permeability than common techniques involving water, gas, surfactants or combinations of the three.

Copper foam turns carbon dioxide into useful chemicals Posted: 12 Aug 2014 01:37 PM PDT Scientists have discovered that copper foam could provide a new way of converting excess carbon dioxide into useful industrial chemicals.

Digital literacy reduces cognitive decline in older adults, experts find Posted: 12 Aug 2014 01:37 PM PDT Researchers have found a link between digital literacy and a reduction in cognitive decline, according to a study. The data measures delayed recall from a 10-word-list learning task across 5 separate measurement points. Higher wealth, education and digital literacy improved delayed recall, while people with functional impairment, diabetes, cardiovascular diseases, depressive symptoms or no digital literacy showed decline.

Insights into a new class of semiconducting materials Posted: 12 Aug 2014 01:35 PM PDT A new paper describes investigations of the fundamental optical properties of a new class of semiconducting materials known as organic-inorganic 'hybrid' perovskites.

Imaging system guides brain tumor removal to improve patient outcomes Posted: 12 Aug 2014 01:34 PM PDT NIBIB-funded researchers have developed an imaging system that rapidly and accurately detects a molecular marker found in brain gliomas. It promises to improve the precision of these difficult surgeries by enabling the complete removal of the tumor, while reducing residual damage to brain tissue and neural function.

Making eco-friendly 'pre-fab nanoparticles': Versatile, water-soluble nano-modules Posted: 12 Aug 2014 01:33 PM PDT Materials chemists, polymer scientists and device physicists have reported on a breakthrough technique for controlling assembly of nanoparticles over multiple length scales that may allow cheaper, ecologically friendly manufacture of organic photovoltaics and other electronic devices.

Prostate cancer diagnosis improves with MRI technology Posted: 12 Aug 2014 10:35 AM PDT MRI technology has been melded with a traditional ultrasound prostate exam to create a three-dimensional map of the prostate that allows physicians to view growths that were previously undetectable. "With an ultrasound exam, we are typically unable to see the most suspicious areas of the prostate so we end up sampling different parts of the prostate that statistically speaking are more likely to have cancer," said one expert. "The MRI is a game-changer. It allows us to target the biopsy needles exactly where we think the cancer is located. It's more precise."

Drastically reducing number of potential future hip fractures with new tool Posted: 12 Aug 2014 09:17 AM PDT A new tool is being developed by experts that automatically searches medical images for early signs of osteoporosis in the spine by identifying fractures there and could help reduce the number of future potentially fatal hip fractures. Scientists intend to develop specialist computer software that can be easily incorporated into radiology departments in hospitals.
