Researchers urge caution on wearable health devices

Wed, 02/03/2016 - 16:10
Wearable devices to monitor health are not always reliable or secure according to research. The market for digital devices like smartwatches and fitness bands is growing, with 19 million likely to be sold worldwide this year. They can measure everything from heart rate to physical activity, temperature and even mental wellbeing.

Anonymous browsing hinders online dating signals

Wed, 02/03/2016 - 16:09
Big data and the growing popularity of online dating sites may be reshaping a fundamental human activity: finding a mate, or at least a date. Yet a new study finds that certain longstanding social norms persist, even online.In a large-scale experiment conducted through a major North American online dating website, a team of management scholars from Canada, the US and Taiwan examined the impact of a premium feature: anonymous browsing.

Researchers discover new phase of boron nitride and a new way to create pure c-BN

Wed, 02/03/2016 - 16:09
Researchers have discovered a new phase of the material boron nitride, which has potential applications for both manufacturing tools and electronic displays. The researchers have also developed a new technique for creating cubic boron nitride (c-BN) at ambient temperatures and air pressure, which has a suite of applications, including the development of advanced power grid technologies.

Collaboration between humans and robots

Wed, 02/03/2016 - 14:11
The new dimension of collaboration between humans and robots can be measured in just a few centimeters: the latest generation of high-precision sensors tells the robotic arms of today’s manufacturing assistants to stop whenever a person gets near. This happens so fast and so reliably that the otherwise standard safety barrier can be dispensed with. And it is this level of safety that makes it possible for people and machines to work hand in hand, in turn allowing companies to completely redesign how humans and robots can share tasks.

Internet use increases social inequalities

Wed, 02/03/2016 - 14:11
Internet use is driving a greater wedge in our communities, increasing existing inequalities between rich and poor, a new study reveals.

Professor creates video games that redefine art

Wed, 02/03/2016 - 00:24
Eddo Stern straddles the world of fine art and game design to ask fundamental questions about what is real.

Building a foundation for computer science for all

Tue, 02/02/2016 - 19:37
Computer science has become a new basic skill, essential in order to excel in an increasingly computational and data-intensive world. However, access to computer science (CS) at the K-12 levels remains limited. CS is taught in less than 25 percent of US high schools. Rural and high-need schools are even less likely to offer it. Moreover, in schools that do offer CS, students of color and girls often participate in very low numbers.

Using mathematics to improve human health

Tue, 02/02/2016 - 19:31
Scientists have used mathematics as a tool to provide precise details of the structure of protein nanoparticles, potentially making them more useful in vaccine design.

Exploring gambles reveals foundational difficulty behind economic theory (and a solution)

Tue, 02/02/2016 - 17:40
Ole Peters and Murray Gell-Mann asked: Might there be a foundational difficulty underlying our current economic theory? Is there some hidden assumption, possibly centuries old, behind not one but many of the current scientific problems in economic theory? Such a foundational problem could have far-reaching practical consequences because economic theory informs economic policy. The story that emerged is a fascinating example of how human understanding evolves, sticks, unsticks, and branches.

Cold War Russian cipher may finally be solved

Tue, 02/02/2016 - 17:25
The Soviet VIC cipher used in the early 1950s, long known for being complex and secure, may not be as impossible to crack as initially assumed. According to a recent article cracking the infamous Soviet VIC cipher is possible if one understands the enciphering algorithm. If one does not know the algorithm, the cipher indeed lives up to its reputation, and becomes nearly impossible to decipher.

Smallest lattice structure worldwide

Tue, 02/02/2016 - 17:12
Scientists have now presented the smallest human-made lattice structure. Its struts and braces are made of glassy carbon. They are smaller than comparable metamaterials by a factor of five. The small dimension results in so far unreached ratios of strength to density. Applications as electrodes, filters or optical components might be possible.

New method for producing tiny cracks in electrodes may mean big boost for nanoelectronics

Tue, 02/02/2016 - 16:08
The next generation of electronics, as well as ultra-sensitive medical diagnostics, could depend on near atomic scale cracks — or nanogaps — in electrodes. Now, researchers have developed a method that could pave the way for mass production of nanogap electrodes.

Can games help train future doctors and nurses?

Tue, 02/02/2016 - 14:14
Kaizen, a Web-based gaming platform, promotes learning through a mix of education, entertainment and competition. Named for a Japanese phrase meaning "continuous improvement," Kaizen presents players with short, multiple-choice scenarios designed to test their clinical knowledge.

Scientist creates artificial intelligence algorithm to monitor machinery health

Tue, 02/02/2016 - 14:12
An artificial intelligence algorithm greatly increases accuracy in diagnosing the health of complex mechanical systems. In blind tests using data coming from highly unpredictable and real-life situations, the algorithm consistently achieves over 90 percent accuracy, say the researchers.

Super Mario gets social intelligence

Computer scientists help the popular jump ‘n’ run game figures learn to observe, collaborate – and even switch allegiance.

Planning for a disease outbreak? There's a game for that

Tue, 02/02/2016 - 03:03
Computer scientists and statisticians are turning disease outbreak planning exercises into a game. They’re creating powerful new software that can predict, simulate and analyze a major disease outbreak – all in the form of an intuitive, multiplayer game.

When loved ones battle cancer, families head to Web for information more than support

Tue, 02/02/2016 - 02:59
Loved ones of cancer patients are likely to search for further information about the disease online but less inclined to seek emotional support from social media forums, according to a study. It is fairly common for loved ones of cancer patients to develop depression or anxiety disorders, but there aren't many studies focusing specifically on cancer patients' caregivers and family members, said the study's author.
