Electronic skin points the way north

Thu, 11/15/2018 - 7:45am
Researchers have developed an electronic skin (e-skin) with magnetosensitive capabilities, sensitive enough to detect and digitize body motion in the Earth's magnetic field. As this e-skin is extremely thin and malleable, it can easily be affixed to human skin to create a bionic analog of a compass. This might not only help people with orientation issues, but also facilitate interaction with objects in virtual and augmented reality.

What's next for smart homes: An 'Internet of Ears?'

Thu, 11/15/2018 - 5:30am
A pair of electrical engineering and computer science professors have been experimenting with a new suite of smart-home sensors. Their system would read not only the vibrations, sounds -- and even the specific gait, or other movements -- associated with people and animals in a building, but also any subtle changes in the existing ambient electrical field.

Putting food-safety detection in the hands of consumers

Wed, 11/14/2018 - 10:19am
Researchers have developed a wireless system that leverages the cheap RFID tags already on hundreds of billions of products to sense potential food contamination -- with no hardware modifications needed. With the simple, scalable system, the researchers hope to bring food-safety detection to the general public.

Study opens route to ultra-low-power microchips

Mon, 11/12/2018 - 4:18pm
Researchers have developed a new way of controlling magnetism in materials, which could lead to new low-power technologies for memory, computing, and sensing devices.

New framework pushes the limits of high-performance computing

Mon, 11/12/2018 - 4:17pm
Researchers found a way to give high-performance computing data systems the flexibility to thrive with a first-of-its-kind framework called BespoKV, perhaps helping to one day achieve the HPC goal of performing at the exascale, or a billion billion calculations per second.

AI capable of outlining in a single chart information from thousands of scientific papers

Mon, 11/12/2018 - 6:59am
Scientists have developed a Computer-Aided Material Design (CAMaD) system capable of extracting information related to fabrication processes and material structures and properties -- factors vital to material design -- and organizing and visualizing the relationship between them. The use of this system enables information from thousands of scientific and technical articles to be summarized in a single chart, rationalizing and expediting material design.

Big data used to predict the future

Fri, 11/09/2018 - 7:14am
Technology is taking giant leaps and bounds, and with it, the information with which society operates daily. Nevertheless, the volume of data needs to be organized, analyzed and crossed to predict certain patterns. This is one of the main functions of what is known as 'Big Data', the 21st century crystal ball capable of predicting the response to a specific medical treatment, the workings of a smart building and even the behavior of the Sun based on certain variables.

Artificial intelligence may fall short when analyzing data across multiple health systems

Fri, 11/09/2018 - 7:14am
A new study shows deep learning models must be carefully tested across multiple environments before being put into clinical practice.

Making steps toward improved data storage

Fri, 11/09/2018 - 7:14am
Researchers created the world's most powerful electromagnetic pulses to control a data-storage material's physical form, leading to a potential way to scale down memory devices and revolutionize how computers handle information.

Codebreaker Turing's theory explains how shark scales are patterned

Wed, 11/07/2018 - 3:49pm
A system proposed by world war two codebreaker Alan Turing more than 60 years ago can explain the patterning of tooth-like scales possessed by sharks, according to new research.

Batteryless smart devices closer to reality

Wed, 11/07/2018 - 2:29pm
Researchers have taken a huge step towards making smart devices that do not use batteries or require charging.

Summer birth and computer games linked to heightened short-sight risk in childhood

Tue, 11/06/2018 - 3:47pm
Summer birth and hours spent playing computer games are linked to a heightened risk of developing short or near sightedness (myopia) in childhood, indicates a twin study.

Why some Wikipedia disputes go unresolved

Tue, 11/06/2018 - 2:18pm
Study identifies reasons for unsettled editing disagreements and offers predictive tools that could improve deliberation.

How ideas go viral in academia: Where idea starts is key

Tue, 11/06/2018 - 12:04pm
How ideas move through academia may depend on where those ideas come from as much as their quality, a new study suggests.

Brain-computer interface advances improve prosthetics, therapies

Tue, 11/06/2018 - 9:14am
Advances in connecting neural stimulation to physical control of the body are transforming the development of prosthetics and therapeutic training for people with disabilities, according to new research.

Subtle visual cues nudge users to reveal more in online forum

Tue, 11/06/2018 - 8:16am
Pictures may be worth a thousand words, but icons may be even more powerful in nudging people to disclose more information online, according to an interdisciplinary team.

New attacks on graphics processors endanger user privacy

Mon, 11/05/2018 - 11:31am
Web browsers use GPUs to render graphics on desktops, laptops, and smart phones. GPUs are also used to accelerate applications on the cloud and data centers. GPUs are usually programmed using application programming interfaces, or APIs, such as OpenGL. OpenGL is accessible by any application on a desktop with user-level privileges. Since desktop or laptop machines by default come with the graphics libraries and drivers installed, the attack can be implemented easily using graphics APIs.

One step closer to complex quantum teleportation

Fri, 11/02/2018 - 7:59am
For future technologies such as quantum computers and quantum encryption, the experimental mastery of complex quantum systems is inevitable. Scientists have now succeeded in making another leap. While physicists are trying to increase the number of so-called qubits, the other researchers are pursuing the idea to use more complex quantum systems. The developed methods and technologies could in the future enable the teleportation of complex quantum systems.

To fight email scammers, take a different view, literally

Thu, 11/01/2018 - 10:37am
A team of researchers is helping law enforcement crack down on email scammers, thanks to a new visual analytics tool that dramatically speeds up forensic email investigations and highlights critical links within email data. Email scams are among the most prevalent, insidious forms of cybercrime.
