Screen to beam technology: The rise of haptic interfaces

Wed, 11/23/2016 - 19:26
Haptic interfaces have been readily adopted because of their intuitive ease of use and convenience. Obvious examples are the screens for your mobile phone or other computing devices where keyboards have been eliminated. A combination of two technologies can provide both ease of use in information analysis and a wide area of application in sharing and making use of the analysis.

New quantum states for better quantum memories

Wed, 11/23/2016 - 14:07
How can quantum information be stored as long as possible? An important step forward in the development of quantum memories has been achieved by a research team.

Mothers' early support boosts children's later math achievement

Wed, 11/23/2016 - 00:30
Early math knowledge is as important as early literacy for children's subsequent achievement. In fact, research has shown that early math skills predict later school success better than early reading skills, and can even predict income in adulthood. Now a new longitudinal study has found that young children whose mothers supported them during play, specifically in their labeling of object quantities, had better math achievement at ages 4-½ and 5 years.

Supersonic spray yields new nanomaterial for bendable, wearable electronics

Tue, 11/22/2016 - 22:48
An ultrathin film of fused silver nanowires that is both transparent and highly conductive to electric current has been produced by a cheap and simple method devised by an international team of nanomaterials researchers.

Google Glass technology may slow down response time

Tue, 11/22/2016 - 17:40
Heads-up display technology -- think Google Glass -- offers lots of information to users in seconds, literally in front of their eyes. Access to information is critical in today's fast-paced world, but new research indicates that the multitasking needed to process that readily available information may slow down the brain's response time.

Malware turns PCs into eavesdropping devices

Tue, 11/22/2016 - 17:39
Researchers have demonstrated malware that can turn computers into perpetual eavesdropping devices, even without a microphone.

Scientists unveil software that revolutionizes habitat connectivity modeling

Tue, 11/22/2016 - 17:35
A trio of scientists has unveiled a groundbreaking computational software called "GFlow" that makes wildlife habitat connectivity modeling vastly faster, more efficient and superior in quality and scope.

Single photon converter: key component of quantum internet

Tue, 11/22/2016 - 17:27
A team of physicists has constructed and tested a compact, efficient converter capable of modifying the quantum properties of individual photons. The new device should facilitate the construction of complex quantum computers, and in the future may become an important element in global quantum networks, the successors of today’s Internet.

Innovative technique to curtail illegal copying of digital media

Tue, 11/22/2016 - 17:22
In today's digital world it can be challenging to prevent photos, videos and books from being illegally copied and distributed. A new light-based technique is making it more practical to create secure, invisible watermarks that can be used to detect and prosecute counterfeiting.

Pushing boundaries of drone control for extreme conditions

A researcher aims to maximize the capabilities of drones regardless of platform or environmental conditions.

Shaking things up with more control

Tue, 11/22/2016 - 16:10
Excessive vibrations – excessive to the point of injury – have been prominent in the news recently, but researchers have developed an algorithm that could help machines avoid getting trapped in resonant motion. Using a combination of computer simulations and experiments, they found that by carefully increasing and decreasing the speed of a rotor, they could nudge it past its resonant frequency.

Researchers demonstrate ability of machine-learning algorithms in echocardiographic interpretation and diagnosis of HCM

Tue, 11/22/2016 - 13:08
Computer algorithms can automatically interpret echocardiographic images and distinguish between pathological hypertrophic cardiomyopathy (HCM) and physiological changes in athletes' hearts, according to research.

Spray printed crystals to move forward organic electronic applications

Tue, 11/22/2016 - 12:59
New technology could revolutionize printed electronics by enabling high quality semiconducting molecular crystals to be directly spray-deposited on any surface.

New clues emerge in 30-year-old superconductor mystery

Mon, 11/21/2016 - 22:40
One of the greatest mysteries of experimental physics is how so-called high-temperature superconducting materials work. Despite their name, high-temperature superconductors operate at chilly temperatures less than minus 135 degrees Celsius. They can be used to make superefficient power cables, medical MRIs, particle accelerators, and other devices. Cracking the mystery of how these materials work could lead to superconducting devices that operate at room temperatures, and could revolutionize electrical devices.

A good combination: Model and experiment for a deeper look

Mon, 11/21/2016 - 21:28
Doctors performing medical check-ups want a full picture of the patient's health without using the scalpel. Engineers who want to investigate the stability of a bridge without cutting into it are in the same position. Non-destructive testing methods play a major role in guaranteeing quality and safety, driving substantial interest in refined methodologies. Now researchers have developed a method that gives a precise picture of the inner world of objects combining a computerized model and experiment.

Weather the storm: Improving Great Lakes modeling

Mon, 11/21/2016 - 19:46
Water and atmospheric processes are inseparable. Now, there is a supercomputer model that couples climate and hydrodynamic factors for the Great Lakes region. The new model will be useful for climate predictions, habitat modeling for invasive species, oil spill mitigation and other environmental research.

What your choice of smartphone says about you

Mon, 11/21/2016 - 19:42
Android users are more honest than iPhone users say psychologists, in a study published this week which is the first to find a link between personality and smartphone type.

Computer scientists work to prevent hackers from remotely controlling cars

Mon, 11/21/2016 - 16:23
A luxury vehicle today contains multiple computers. During an hour's drive, it thus produces multiple gigabytes of data. Even less expensive vehicles are now brimming with information technology. The growing interconnection of the individual components opens dangerous security holes. One of these has now been closed by computer scientists -- with the help of software that manufacturers can retrofit into any car.
