Robotically assisted bypass surgery reduces complications after surgery, cuts recovery

Tue, 10/28/2014 - 12:26
Robotically assisted coronary artery bypass grafting surgery is a rapidly evolving technology that shortens hospital stays and reduces the need for blood products, while decreasing recovery times, making the procedure safer and less risky, experts say.

Lack of A level maths leading to fewer female economists in England

Tue, 10/28/2014 - 12:25
A study has found there are far fewer women studying economics than men, with women accounting for just 27 per cent of economics students, despite them making up 57 per cent of the undergraduate population in UK universities. The findings suggest less than half as many girls (1.2 per cent) as boys (3..8 percent) apply to study economics at university, while only 10 per cent of females enroll at university with an A level in maths, compared to 19 per cent of males.

Accuracy of mobile phone population mapping demonstrated

Tue, 10/28/2014 - 12:24
Population maps based on anonymous mobile phone call record data can be as accurate as those based on censuses, an international team of researcher has demonstrated. Their findings show maps made using mobile records are detailed, reliable and flexible enough to help inform infrastructure and emergency planners; particularly in low income countries, where recent population density information is often scarce.

Citizen science network produces accurate maps of atmospheric dust

Mon, 10/27/2014 - 16:03
Measurements by thousands of citizen scientists in the Netherlands using their smartphones and the iSPEX add-on are delivering accurate data on dust particles in the atmosphere that add valuable information to professional measurements. The research team analyzed all measurements from three days in 2013 and combined them into unique maps of dust particles above the Netherlands. The results match and sometimes even exceed those of ground-based measurement networks and satellite instruments.

Insightful mathematics for an optimal run

Mon, 10/27/2014 - 14:04
Sure, we can become better runners by hydrating well, eating right, cross training, and practice. But getting to an optimal running strategy with equations? That's exactly what a pair of mathematicians propose in a new paper.

Organizational needs often forgotten in developing countries’ IT education

Mon, 10/27/2014 - 12:53
A shortage of skilled IT service management professionals constitutes an obstacle for the efficient use of information and communication technology, and is a particular challenge for the least developed countries, such as Tanzania. Tanzanian universities offer a high level of education in, for example, computer science and software design, but not in information technology.

Record data transmission over a specially fabricated fiber demonstrated

Mon, 10/27/2014 - 12:52
Researchers report the successful transmission of a record high 255 Terabits/s over a new type of fibre allowing 21 times more bandwidth than currently available in communication networks. This new type of fiber could be an answer to mitigating the impending optical transmission capacity crunch caused by the increasing bandwidth demand.

Breakthrough in molecular electronics paves way for new generation of DNA-based computer circuits

Sun, 10/26/2014 - 23:52
Scientists have announced a significant breakthrough toward developing DNA-based electrical circuits. Molecular electronics, which uses molecules as building blocks for the fabrication of electronic components, has been seen as the ultimate solution to the miniaturization challenge. However, to date, no one has actually been able to make complex electrical circuits using molecules. Now scientists report reproducible and quantitative measurements of electricity flow through long molecules made of four DNA strands, signaling a significant breakthrough towards the development of DNA-based electrical circuits.

The right to privacy in a big data world: When properly understood, privacy rules essential, experts say

Sat, 10/25/2014 - 19:25
In the digital age in which we live, monitoring, security breaches and hacks of sensitive data are all too common. It has been argued that privacy has no place in this big data environment and anything we put online can, and probably will, be seen by prying eyes. In a new article privacy law expert makes the case that when properly understood, privacy rules will be an essential and valuable part of our digital future.

Relationships benefit when parents, adult children use multiple communication channels

Fri, 10/24/2014 - 18:20
Adult children's relationship satisfaction with their parents is modestly influenced by the number of communication tools, such as cell phones, email, social networking sites, they use to communicate, research has found.

Jetpacks and flamethrowers: Team infuses science into 'Minecraft' modification

Fri, 10/24/2014 - 16:07
The 3-D world of the popular “Minecraft” video game just became more entertaining, perilous and educational, thanks to a comprehensive code modification kit, “Polycraft World.”

Novel software application can stratify early-stage non-small cell lung cancer patients

Thu, 10/23/2014 - 18:23
Computer-Aided Nodule Assessment and Risk Yield, is a novel software tool that can automatically quantitate adenocarcinoma pulmonary nodule characteristics from non-invasive high resolution computed tomography images and stratify non-small cell lung cancer patients into risk groups that have significantly different disease-free survival outcome.

Should a Facebook 'like' be protected free speech?

Thu, 10/23/2014 - 18:20
One billion Facebook users generate 2.7 billion “likes” per day (or 1,875,000 every minute). Increasingly, social media has become a form of social and political engagement, and 47 percent of Facebook users have “liked” political cause-related comments. Protected free speech is a luxury the Western world has long enjoyed, authors of a new article say.

Some online shoppers pay more than others, study shows

Thu, 10/23/2014 - 17:22
Numerous instances of price steering and discrimination on many popular e-commerce retail and travel websites have been uncovered by new research. That's not necessarily a bad thing, researchers say -- so long as the companies are transparent.

Precise, programmable biological circuits

Thu, 10/23/2014 - 14:07
Several new components for biological circuits have been developed by researchers. These components are key building blocks for constructing precisely functioning and programmable bio-computers. "The ability to combine biological components at will in a modular, plug-and-play fashion means that we now approach the stage when the concept of programming as we know it from software engineering can be applied to biological computers. Bio-engineers will literally be able to program in future."

Moving in the quantum world

Thu, 10/23/2014 - 13:18
Simulating the behavior of a single particle can be quite a challenging task in physics; after all, it is microscopic and we usually cannot watch in real time. It becomes even more complicated when you realize that the particle has to follow the laws of quantum physics, which allow it be in two or more places at the same time through a phenomenon called superposition. Understanding how a quantum particle behaves is necessary to enhance our fundamental understanding of the laws of physics.

A strong welfare state mitigates the impact of the Great Recession

Thu, 10/23/2014 - 13:18
There is a general correlation between unemployment and suicide among men. But the weaker the unemployment protection in the country, the stronger the connection. These findings are reported in a comparative study covering thirty countries, focusing the impact of the Great Recession on unemployment and suicide rates.

Online dermatologic follow-up for atopic dermatitis earns equivalent results

Wed, 10/22/2014 - 20:39
An online model for follow-up care of atopic dermatitis, better known as eczema, that gave patients direct access to dermatologists resulted in equivalent clinical improvement compared to patients who received traditional in-person care, a study finds.

Unexpected benefits of adjustable rate mortgages

Wed, 10/22/2014 - 16:35
As would be expected during a time of consumer deleveraging, households applied more than 70 percent of their mortgage savings to reducing outstanding credit card debts. Not only did the lower payments reduce mortgage defaults but credit card delinquencies fell. 'These choices had significant impact on foreclosures, house prices and employment in regions that were more exposed to interest rate declines,' the researchers concluded.
