Your privacy online: Health information at serious risk of abuse, researchers warn

Mon, 02/23/2015 - 17:26
There is a significant risk to your privacy whenever you visit a health-related web page, some researchers warn. An analysis of over 80,000 such web pages shows that nine out of ten visits result in personal health information being leaked to third parties, including online advertisers and data brokers.

3D printed guides can help restore function in damaged nerves

Mon, 02/23/2015 - 15:41
Scientists have succeeded in using a 3-D printed guide to help nerves damaged in traumatic incidents repair themselves. The team used the device to repair nerve damage in animal models and say the method could help treat many types of traumatic injury.

Fever alarm armband: A wearable, printable, temperature sensor

Mon, 02/23/2015 - 13:43
Researchers have developed a 'fever alarm armband,' a flexible, self-powered wearable device that sounds an alarm in case of high body temperature. The flexible organic components developed for this device are well-suited to wearable devices that continuously monitor vital signs including temperature and heart rate for applications in healthcare settings.

Independent home living or healthcare facility? Web tool to speed data collection

Fri, 02/20/2015 - 16:08
By 2030, one in five Americans will be age 65 or older. To understand the role neighborhoods play in seniors' ability to 'age in place' -- living safely and independently in one's home of choice rather than in a healthcare facility -- researchers created a web application that speeds up researchers' data collection.

New technique for making graphene competitor, molybdenum disulfide

Thu, 02/19/2015 - 19:46
Researchers have made an advance in manufacturing molybdenum disulphide, a 2-D material that could compete with graphene for replacing silicon in next-generation electronics. By growing flakes of the material around 'seeds' of molybdenum oxide, they have made it easier to control the size, thickness and location of the material.

Minimizing 'false positives' key to vaccinating against bovine TB

Thu, 02/19/2015 - 19:46
New diagnostic tests are needed to make vaccination against bovine tuberculosis (bovine TB) viable and the number of false positives from these tests must be below 15 out of every 10,000 cattle tested, according to research.

Tracing languages back to their common ancestors through the statistics of sound shifts

Thu, 02/19/2015 - 18:30
A statistical technique that sorts out when changes to words’ pronunciations most likely occurred in the evolution of a language offers a renewed opportunity to trace words and languages back to their earliest common ancestor or ancestors.

New NIST tools to help boost wireless channel frequencies and capacity

Thu, 02/19/2015 - 16:56
To help solve growing problems with wireless bandwidth crowding and support the next generation of mobile technology, researchers are developing measurement tools for channels that are new for mobile communications and that could offer more than 1,000 times the bandwidth of today's cell phone systems.

Mobile app with evidence-based decision support diagnoses more obesity, smoking, and depression

Thu, 02/19/2015 - 16:24
Smartphones and tablets may hold the key to getting more nurses to diagnose patients with chronic health issues like obesity, smoking, and depression -- three of the leading causes of preventable death and disability.

Supercomputer simulations explore how an air-reed instrument generates air flow and sound

Thu, 02/19/2015 - 15:17
Toyohashi Tech's researcher has succeeded in directly predicting sound radiating from a recorder for the first time all over the world. The calculations for this study took two weeks using about 100 nodes of supercomputers. The findings contribute to proposal of a new design of musical instrument easy-to-play or totally new musical instruments.

New approach to distributing computations could make multicore chips much faster

Thu, 02/19/2015 - 15:17
Computer chips' clocks have stopped getting faster. To keep delivering performance improvements, chipmakers are instead giving chips more processing units, or cores, which can execute computations in parallel. But the ways in which a chip carves up computations can make a big difference to performance.

Neck pain can be changed through altered visual feedback

Thu, 02/19/2015 - 15:16
Using virtual reality to misrepresent how far the neck is turned can actually change pain experiences in individuals who suffer from chronic neck pain, according to research.

Digital games and classroom learning: Study finds helpful features, gaps

Thu, 02/19/2015 - 14:04
A new report on how teachers use video games in classrooms identifies features they find most useful to track student learning, as well as gaps where better tools could help link games more closely to the curriculum.

How social media can help, hurt companies during product recalls

Wed, 02/18/2015 - 19:14
Companies are starting to embrace social media as a viable disclosure channel for product recalls, with the goal of limiting and repairing damage to the firms' reputation. Using a sample of 405 consumer product recalls between 2000 and 2012, researchers found that corporate social media, in general, lessens negative price reactions to product recall announcements.

Social media can help alert students during campus emergencies, study finds

Wed, 02/18/2015 - 19:14
Using social networking sites like Facebook and Twitter to spread information during campus emergencies can help keep students safer, according to new research.

How income fraud made the housing bubble worse

Wed, 02/18/2015 - 14:30
New research reveals that, in low-income zip codes, IRS-reported incomes and earnings reported on mortgages in fact differed wildly from 2002 to 2005. The researchers place the blame for falsified earnings listed on mortgage applications -- which the researchers call "buyer income overstatement" -- on brokers producing mortgages intended to be sold as securities.

New solder for semiconductors creates technological possibilities

Tue, 02/17/2015 - 20:40
Scientists have demonstrated how semiconductors can be soldered and still deliver good electronic performance.

Building a more versatile frequency comb: Newly developed frequency combs can operate at higher power

Tue, 02/17/2015 - 18:12
Researchers have developed a room temperature frequency comb with increased power based on quantum cascade lasers. Since the discovery of optical frequency combs in the 1990s, many applications in metrology, spectroscopy, and frequency synthesis have emerged. Similar to the way a grandfather clock's pendulum ticks off the seconds before signaling the gears to turn its hands, frequency combs count oscillations and convert them into useful electronic signals.

Some bilinguals use emoticons more when chatting in non-native language

Tue, 02/17/2015 - 16:46
One group of bilingual speakers used emoticons more often when typing in their second language in casual, online communication than they did when typing in their native tongue, a study has found.
