'Funneling' behind severe flooding on the Clyde

Thu, 09/15/2016 - 12:55
A “funneling” effect has been a major factor in severe flooding on the River Clyde in recent years, according to a study by English mathematicians.

Big pixel initiative develops remote sensing analysis to help map global urbanization

Wed, 09/14/2016 - 18:20
Researchers are using unique tools to map urban areas around the globe, potentially revolutionizing large-scale analysis of urbanization, land use and city growth.

Complex materials can self-organize into circuits, may form basis for multifunction chips

Wed, 09/14/2016 - 17:09
Researchers studying the behavior of nanoscale materials have uncovered remarkable behavior that could advance microprocessors beyond today’s silicon-based chips.

To image or not?

Wed, 09/14/2016 - 14:57
A Library of Evidence has now been launched, a free, publicly accessible online resource to help clinicians choose the most appropriate imaging tests based on the best available research evidence. The resource is designed to avert unnecessary imaging and contain rising health care costs associated with this practice. The Library debuts on the eve of a new federal law that mandates the use of evidence-based decision-support systems by clinicians caring for federally insured patients. Over time, the Library will expand to include other domains of clinical decision-making, such as choosing appropriate medications or ordering other tests and procedures.

Pioneering research paves the way towards exascale optical networks

Wed, 09/14/2016 - 13:03
In the face of increasing bandwidth demands, ground-breaking research has demonstrated solutions for network infrastructure to address the looming network capacity crunch.

Similar nanomaterials behave differently: Why?

Wed, 09/14/2016 - 12:58
Nanotubes can be used for many things: electrical circuits, batteries, innovative fabrics and more. Scientists have noted, however, that nanotubes, whose structures appear similar, can actually exhibit different properties, with important consequences in their applications. Carbon nanotubes and boron nitride nanotubes, for example, while nearly indistinguishable in their structure, can be different when it comes to friction. A new study has created computer models of these crystals and studied their characteristics in detail and observed differences related to the material’s chirality.

Computer algorithm illuminates need of high-volume hospitals and standard care for transplant patients

Tue, 09/13/2016 - 21:34
Using the results from a computerized mathematical model, researchers investigated whether they could improve heart and lung transplantation procedures by transferring patients from low-volume to high-volume transplant centers.

Hybrid computational strategy for efficient sequencing of massive genome datasets

Tue, 09/13/2016 - 18:15
Computing experts have developed a novel hybrid computational strategy to efficiently discover genetic variants on an unprecedented scale.

New fabric uses sun and wind to power devices

Tue, 09/13/2016 - 18:15
Fabrics that can generate electricity from physical movement have been in the works for a few years. Now researchers have taken the next step, developing a fabric that can simultaneously harvest energy from both sunshine and motion.

Language delivers fourfold speedups on big-data problems

Tue, 09/13/2016 - 17:41
Experts are presenting a new programming language, called Milk, that lets application developers manage memory more efficiently in programs that deal with scattered data points in large data sets.

Touchscreens may boost motor skills in toddlers

Tue, 09/13/2016 - 16:47
Does your toddler use a touchscreen tablet? A recent study has shown that early touchscreen use, and in particular actively scrolling the screen, correlates with increased fine motor control in toddlers.

Tuning materials and devices to adapt to their environment

Tue, 09/13/2016 - 16:45
By leveraging molecular beam epitaxy deposition and high-quality materials with large dielectric constants, researchers pursue future radio-frequency materials and devices capable of being 'tuned' to adapt to changing environments.

Understanding how flat phosphorus grows

Tue, 09/13/2016 - 16:09
Modeling the growth of tiny flakes of a two-dimensional form of phosphorus could help researchers one day produce better electronics, say scientists.

Peculiar metals? Insulator or conductor

Tue, 09/13/2016 - 15:57
The electronic energy states allowed by quantum mechanics determine whether a solid is an insulator or whether it conducts electric current as a metal. Researchers have now theoretically predicted a novel material whose energy states exhibit a hitherto unknown peculiarity.

Lightweight robots in manual assembly

Tue, 09/13/2016 - 14:05
In recent years, human-robot cooperation – also known as human-robot collaboration, or HRC – has taken center stage at trade fairs. The term applies to any situation where robots work directly alongside humans without safety barriers on the manufacturing floor. In such cases, the work zones of robots and workers overlap instead of being strictly separated. The low entry prices and big media interest in the technology created a wave of hype. But is the cost really all that low, and are the new robots really safe? Or is it a case of companies having unrealistic expectations?

App vs. website: Which best protects your privacy?

Mon, 09/12/2016 - 19:16
Should you use the app -- or a web browser -- for that? That's the ques­tion that researchers ask in a new study that explores how free app- and web-based ser­vices on Android and iOS mobile devices com­pare with respect to pro­tecting users' privacy.

Lightweight, wearable tech efficiently converts body heat to electricity

Mon, 09/12/2016 - 17:27
Researchers have developed a new design for harvesting body heat and converting it into electricity for use in wearable electronics. The experimental prototypes are lightweight, conform to the shape of the body, and can generate far more electricity than previous lightweight heat harvesting technologies.

3D printed material helps to regenerate bone

Mon, 09/12/2016 - 16:27
A biomaterial with the ability to serve as a support for regenerating bone tissue has been developed by researchers. The material is biodegradable and can be printed in 3D with controlled porosity.

New software helps to identify course of cancer metastasis, tumor 'evolution'

Sat, 09/10/2016 - 02:35
Tumors also differ among patients with the same type of cancer, so how is a physician able to prescribe a tailored regimen for the patient? Researchers approach to infer the evolutionary track of tumor cells by surveying two types of mutations -- somatic copy number alterations and single-nucleotide alterations -- derived from multiple samples taken from a single patient.

What's nature worth? Count the selfies
