Scientists have made major improvements in computer processing using an emerging class of magnetic materials called 'multiferroics,' and these advances could make future devices far more energy-efficient than current technologies.
Classroom programs designed to improve elementary school students' social and emotional skills can also increase reading and math achievement, even if academic improvement is not a direct goal of the skills building, according to a study. The benefit holds true for students across a range of socio-economic backgrounds.
Mini-computers with head-mounted display like 'Google Glass' don't just alarm privacy activists. Rather, they also enable applications increasing data protection. Computer scientists demonstrate this by combining Google Glass with cryptography methods and novel techniques of image processing to withdraw money at cash machines or to read encrypted documents.
Researchers have developed a computational tool designed to guide future research on biochemical pathways by identifying which components in a biological system are related to specific biochemical processes, including those processes responsible for gene expression, cell signaling, stress response, and metabolism.
The statistical evaluation of digital user data is of vital importance for analyzing trends. But it can also undermine the privacy. Computer scientists have now developed a novel cryptographic method that makes it possible to collect data and protect the privacy of the user at the same time.
Scientists have created a robotic drumming prosthesis with motors that power two drumsticks. The first stick is controlled both physically by the musicians’ arms and electronically using electromyography (EMG) muscle sensors. The other stick “listens” to the music being played and improvises.
The last decade has seen a remarkable shift in how people use the internet in relation to their health and it is now talked of as a routine feature of being ill. This study examined interviews with patients conducted between 2001 and 2013 and explored how people talked about the internet, capturing changing attitudes towards the use of the internet for health across the last decade.
Researchers have analyzed the websites of nearly 50 banks from the EU to check whether any user, even if disabled, has equal access. The results show that this right is not fulfilled in 74 percent of cases, and therefore they demand greater interest from financial entities in this technological and social problem.
New technology could make flexible electronics such as roll-up tablet computers, widely available in the near future. So far, this area of electronic design has been hampered by unreliability and complexity of production.
NASA has successfully concluded a remotely controlled test of new technologies that would empower future space robots to transfer hazardous oxidizer -- a type of propellant -- into the tanks of satellites in space today.
Researchers have succeeded in producing a prototype of a vibration-damping material that could change the world of mechanics forever. The material of the future is not only able to damp vibrations completely. It can also specifically conduct certain frequencies further.
Radio waves are used for many measurements and applications, for example, in communication with mobile phones, MRI scans, scientific experiments and cosmic observations. But 'noise' in the detector of the measuring instrument limits how sensitive and precise the measurements can be. Now researchers have developed a new method where they can avoid noise by means of laser light and can therefore achieve extreme precision of measurements.
D-Wave quantum processor passes tests indicating that it uses special laws of quantum mechanics to operate. A key task for researchers has been to determine whether D-Wave processors operate as hoped -- using the special laws of quantum mechanics to offer potentially higher-speed processing, instead of operating in a classical, traditional way.
Making your own stuff with a 3-D printer is vastly cheaper than what you'd pay for manufactured goods, even factoring in the cost of buying the plastic filament. Yet, you can drive the cost down even more by making your own filament from old milk jugs. And, while you are patting yourself on the back for saving 99 cents on the dollar, there's a bonus: you can feel warm and fuzzy about preserving the environment. Making your own plastic 3-D printer filament from milk jugs uses less energy -- often a lot less -- than recycling milk jugs conventionally.
Disasters both natural and human-caused can damage or destroy data and communications networks. New information on strategies that can mitigate the impacts of these disasters.
Criminals don't have to pick your pocket to get what they want out of your mobile. But a certifiably secure operating platform is being developed by researchers so that consumers can be confident that their mobile data is safe.
A split-second snapshot of an early stage of protein formation could someday lead to more effective antibiotics. Proteins are the worker bees of cells. They get rid of waste, transmit cellular signals and carry out the chemical reactions that enable the human body to function. Without proteins, cells would be unable to function, replicate, and die. Viruses, bacteria and cancer cells also need proteins to reproduce. Using computer modelling, researchers examined the role of one specific protein, and its ultimate effect on health.
Software developers are spending about the half of their time detecting errors and resolving them. Projected onto the global software industry, this would amount to a bill of about 312 billion US dollars every year. Researchers are now automating the process.
In the future, computers and humans will cooperate more seamlessly: perhaps by easier access to data or by the intuitive control of programs and robots. Conference exhibits along this line include gesture-controlled communication, firewalls to data management and computer-supported surgery.
An increasing number of unsecured, computer-guided production machinery and networks in production facilities are gradually evolving into gateways for data theft. New security technologies may directly shield the sensitive data that is kept there.
