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.
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 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.
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 is driving a greater wedge in our communities, increasing existing inequalities between rich and poor, a new study reveals.
Eddo Stern straddles the world of fine art and game design to ask fundamental questions about what is real.
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.
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.
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.
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.
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.
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.
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.
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.
Computer scientists help the popular jump ‘n’ run game figures learn to observe, collaborate – and even switch allegiance.
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.
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.
Researchers are using a mathematical tool to help determine which concussion patients will go on to suffer migraine headaches, according to a new study.
Inventory management has been the focus of three researchers for more than 10 years, Their latest study developed a new mathematical model to apply to inventory problems.
New transparent metamaterials under development could make possible computer chips and interconnecting circuits that use light instead of electrons to process and transmit data, representing a potential leap in performance.
