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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Using social networking sites like Facebook and Twitter to spread information during campus emergencies can help keep students safer, according to new research.
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.
Scientists have demonstrated how semiconductors can be soldered and still deliver good electronic performance.
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.
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.
A new, automated method for classifying hundreds of kilometres of the deep sea floor in a way that is more cost efficient, quicker and more objective than previously possible has been developed by researchers.
