An atomically thin material may lead to the thinnest-ever imaging platform. Synthetic two-dimensional materials based on metal chalcogenide compounds could be the basis for superthin devices.
It's like a scene from a gamer's wildest dreams: 12 high-definition, 55-inch 3-D televisions all connected to a computer capable of supporting high-end, graphics-intensive gaming. On the massive screen, images are controlled by a Wii remote that interacts with a Kinnect-like Bluetooth device (called SmartTrack), while 3-D glasses worn by the user create dizzying added dimensions.
Despite showing interest in web or mobile apps to help manage their type 2 diabetes, only a small number of older adults actually use them, says a new study. Approximately 2.2 million Canadians are living with type 2 diabetes, 2 million of whom are age 50 or older. A study found that although more than 90 per cent of research participants owned a computer or had daily Internet access, just 18 per cent used applications on this technology to help manage their diabetes. While almost half owned smartphones, only 5 per cent used them to manage their disease.
Researchers from the University of Southampton have revealed a breakthrough in optical fiber communications. They developed an approach that enables direct modulation of laser currents to be used to generate highly advanced modulation format signals. The research explores a radically new approach to the generation of spectrally-efficient advanced modulation format signals as required in modern optical communication systems.
Personalized advertisements on the Internet not only attract more attention, they also remain in our memory longer than impersonal ads. People who surf the internet and shop online leave many traces of their behavior behind. These data are increasingly being used by companies to present ads on their websites that are intended to meet people's individual interests and preferences.
Scientists have characterized the electronic and magnetic structure in artificially synthesized materials called transition metal oxides.
If data could be encoded without current, it would require much less energy and make things like low-power, instant-on computing a ubiquitous reality. Scientists have made a breakthrough in that direction with a room-temperature magnetoelectric memory device. Equivalent to one computer bit, it exhibits the holy grail of next-generation nonvolatile memory: magnetic switchability, in two steps, with nothing but an electric field.
For decades, neuroscientists have been trying to design computer networks that can mimic visual skills such as recognizing objects, which the human brain does very accurately and quickly. Until now, no computer model has been able to match the primate brain at visual object recognition during a brief glance. Now neuroscientists have found that one of the latest generation of 'deep neural networks' matches the primate brain.
Scientists have built a computer model that has uncovered disease-causing mutations in large regions of the genome that previously could not be explored. Their method seeks out mutations that cause changes in 'gene splicing,' and has revealed unexpected genetic determinants of autism, colon cancer and spinal muscular atrophy.
A new mapping tool makes preparing for natural disasters and responding to their aftermath easier than ever. Researchers have developed a computer model that analyzes networks of interconnected roads to predict the speediest routes for rescuers to take using real-time data uploaded by aid workers on the ground.
Scientists are tackling one of the biggest barriers to the use of robots in emergency response: energy efficiency. They are developing technology that will dramatically improve the endurance of legged robots, helping them operate for long periods while performing the types of locomotion most relevant to disaster response scenarios.
Scientists have taken a significant step in our understanding of superconductivity by studying the strange quantum events in a unique superconducting material.
Searching for new ways to develop efficient, flexible networks, physicists discovered the designs of spider webs and leaf venation, refined across thousands of years of evolution, are worthy models for the next generation of optoelectronic applications.
Big data may be the next new thing to hit the fashion industry's runways, according to a team of researchers.
Researchers have used an electric field to reverse the magnetization direction in a multiferroic spintronic device at room temperature, a demonstration that points a new way towards spintronics and smaller, faster and cheaper ways of storing and processing data.
A lens-free microscope that can be used to detect the presence of cancer or other cell-level abnormalities with the same accuracy as larger and more expensive optical microscopes, has been developed by researchers. The invention could lead to less expensive and more portable technology for performing common examinations of tissue, blood and other biomedical specimens. It may prove especially useful in remote areas and in cases where large numbers of samples need to be examined quickly.
Researchers have used several different ways of testing Hamilton's rule, the core mathematical formula of kin selection, as an explanation for the evolution of much altruistic behavior in animals. These vary in their realism and their ability to generate predictions. The variety of approaches, as well as different views about what constitutes an explanation, helps explain a divisive debate about the importance of kin selection in evolution. A new criterion of 'causal aptness' could help resolve disputes.
Bullies and mean girls have been around forever but, with the arrival of smartphones and social media, meanness has taken on new forms and dramatically extended its reach. Digital abuse is now so widespread, and such are its dramatic effects on victims, that the American Academy of Pediatrics has issued a stern warning about the risks posed by cyberbullying to adolescents’ mental health. But 'how much do we really know about how to tackle online bullies?,' asks a new study.
Research suggests effective self regulation has yet to emerge for the majority of businesses whose privacy policies keep them from sharing consumers’ private information, but are not readable by the average consumer.
