Volumetric 3D printing promises nearly instant builds

Fri, 12/08/2017 - 22:18
By using laser-generated, hologram-like 3D images flashed into photosensitive resin, researchers have discovered they can build complex 3D parts in a fraction of the time of traditional layer-by-layer printing.

Producing hydrogen from methane in a cleaner, cheaper way

Fri, 12/08/2017 - 22:17
A ceramic membrane makes it possible to produce compressed hydrogen from methane with near-zero energy loss.

Revolutionizing electronics using Kirigami

Fri, 12/08/2017 - 20:23
A research team has developed an ultrastretchable bioprobe using a 'Kirigami' designs. The Kirigami-based bioprobe enables one to follow the shape of spherical and large deformable biological samples such as heart and brain tissues. In addition, its low strain-force characteristic reduces the force induced on organs, thereby enabling minimally invasive biological signal recording.

'Toolboxes' for quantum cybersecurity

Fri, 12/08/2017 - 14:55
A quantum information scientist has developed efficient 'toolboxes' comprising theoretical tools and protocols for quantifying the security of high-speed quantum communication.

Insights on fast cockroaches can help teach robots to walk

Fri, 12/08/2017 - 14:55
Scientists show for the first time that fast insects can change their gait -- like a mammal's transition from trot to gallop. These new insights could contribute to making the locomotion of robots more energy efficient.

Screen time before bed linked with less sleep, higher BMIs in kids

Thu, 12/07/2017 - 23:25
It may be tempting to let your kids stay up late playing games on their smartphones, but using digital devices before bed may contribute to sleep and nutrition problems in children, according to researchers.

Virtual reality makes journalism immersive, realism makes it credible

Thu, 12/07/2017 - 23:25
Virtual reality technology may help journalists pull an audience into their stories, but they should avoid being too flashy, or their credibility could suffer, according to a team of researchers.

Hydropower dam energy without sacrificing Mekong food supply: New research offers solution

Thu, 12/07/2017 - 19:17
Nearly 100 hydropower dams are planned for construction along tributaries off the Mekong River's 2,700-mile stretch. In a new article, researchers present a mathematical formula to balance power generation needs with the needs of fisheries downstream.

Rules for superconductivity mirrored in 'excitonic insulator'

Thu, 12/07/2017 - 18:22
Physicists dedicated to creating the working components of a fault-tolerant quantum computer have succeeded in creating an 'excitonic insulator,' a previously unseen state of matter that could be useful for encoding information in a topological quantum computer.

5G set to revolutionize communications and to transform industry

Thu, 12/07/2017 - 17:59
The new generation of 5G mobile networks is the future of the Information and Communication Technologies (ICT) sector -- a true technological revolution that will deliver the Internet of Things.

Security flaw found: 10 million banking app users at risk

Wed, 12/06/2017 - 21:23
Researchers have developed a tool to perform semi-automated security testing of mobile phone apps. After running the tool on a sample of 400 security critical apps, they were able to identify a critical vulnerability in banking apps.

Some video games are good for older adults' brains

Wed, 12/06/2017 - 19:16
Playing 3D-platform video games on a regular basis may improve cognitive functions in seniors and increase grey matter in a brain structure called the hippocampus, a new study suggests.

Controlling spin for memory storage

Wed, 12/06/2017 - 17:25
Researchers have learned how to manipulation of a material's magnetism, making room for faster magnetic memory devices.

Smartphone health apps miss some daily activity of users

Wed, 12/06/2017 - 17:24
The iPhone's Health app and its built-in pedometer miss a significant number of users' steps during a typical day, a new study has found. That's good news for people who self-monitor their physical activity; they are probably getting more exercise than they realize. But the results should raise some caution among researchers who want to tap into the smartphone's enormous potential for gathering health data.

Try this! Researchers devise better recommendation algorithm

Wed, 12/06/2017 - 17:24
Most recommendation systems use a measure called cosine similarity, which seems to work well in practice. Last year, a team of researchers used a new theoretical framework to demonstrate why, indeed, cosine similarity yields such good results. Now they are reporting that they have used their framework to construct a new recommendation algorithm that should work better than those in use today, particularly when ratings data is "sparse" -- that is, when there is little overlap between the products reviewed and the ratings assigned by different customers.

Towards data storage at the single molecule level

Wed, 12/06/2017 - 17:19
Similar to normal hard drives, so-called spin-crossover molecules can save information via their magnetic state. A research team has now managed to place a new class of spin-crossover molecules onto a surface and to improve its storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold.

New algorithm repairs corrupted digital images in one step

Tue, 12/05/2017 - 19:48
Computer scientists have designed a new algorithm that incorporates artificial neural networks to simultaneously apply a wide range of fixes to corrupted digital images. The researchers tested their algorithm by taking high-quality, uncorrupted images, purposely introducing severe degradations, then using the algorithm to repair the damage. In many cases, the algorithm outperformed competitors' techniques, very nearly returning the images to their original state.

In first, 3-D printed objects connect to WiFi without electronics

Tue, 12/05/2017 - 18:01
Engineers have developed the first 3-D printed plastic objects that can connect to other devices via WiFi without using any electronics, including a laundry bottle that can detect when soap is running low and automatically order more.

Experiment demonstrates quantum mechanical effects from biological system

Tue, 12/05/2017 - 18:01
Using green fluorescent proteins obtained from Escherichia coli, researchers have demonstrated quantum mechanical effects from a biological system.

Protein-folding simulations sped up

Tue, 12/05/2017 - 17:00
Proteins are huge molecules whose function depends on how they fold into intricate structures. To understand how these molecules work, researchers use computer modeling to calculate how proteins fold. Now, a new algorithm can accelerate those vital simulations, enabling them to model phenomena that were previously out of reach. The results can eventually help scientists better understand and treat diseases like Alzheimer's.
