Give flawed payments database time to improve

Fri, 12/05/2014 - 15:03
A federal database meant to report the financial ties between doctors and drug and device makers debuted Sept. 30, 2014, with major gaps in the data. Despite those flaws, the public should give the site the chance to improve because its value, even if mostly unrealized, is great, argue experts.

Predicting the storm: Can computer models improve stem cell transplantation?

Fri, 12/05/2014 - 14:49
Is the human immune system similar to the weather, a seemingly random yet dynamical system that can be modeled based on past conditions to predict future states? Scientists believe it is.

Teleophthalmology for screening, recurrence of age-related macular degeneration

Fri, 12/05/2014 - 14:40
No relevant delay between referral and treatment was found when teleophthalmology was used to screen for suspected age-related macular degeneration and, while teleophthalmology monitoring for recurrence of AMD did result in an average longer wait time for treatment reinitiation, it did not result in worse visual outcomes, according to a study.

3-D printed heart could reduce heart surgeries in children

Fri, 12/05/2014 - 14:40
Being able to practice on a model heart allows doctors to optimize the interventional procedure pre-operatively. 3-D models can also be used to discuss the intervention with the medical team, patients and, in the case of congenital heart defects, with parents. It helps everyone affected to better understand what the procedure will involve.

Dopamine helps with math rules as well as mood

Fri, 12/05/2014 - 14:38
Rule-applying neurons work better under the influence of the happy hormone, researchers have found. The chemical messenger dopamine – otherwise known as the happiness hormone – is important not only for motivation and motor skills. It seems it can also help neurons with difficult cognitive tasks, they report.

How stroke survivors could benefit from computer games

Fri, 12/05/2014 - 14:38
Stroke survivors can have “significant” improvement in arm movements after using the Nintendo Wii as physiotherapy, according to researchers. The popular computer remote could be customized to offer bespoke physiotherapy for stroke survivors in their own home, they say.

More smartphone play equals less fun during leisure

Thu, 12/04/2014 - 19:10
Today's smartphones are designed to entertain and are increasingly marketed to young adults as leisure devices. Not surprisingly, research suggests that young adults most often use their phones for entertainment purposes rather than for school or work. Researchers surveyed a random sample of 454 college students to examine how different types of cell phone users experience daily leisure.

Unlocking the potential of big data in the cloud

Thu, 12/04/2014 - 16:09
Cloud computing and Big Data are the two top innovation hubs in ICT. Together they have the potential to become pivotal enhancers of social transformation and economic development for many years to come, experts say.

Engineer applies robot control theory to improve prosthetic legs

Thu, 12/04/2014 - 16:08
New research enables powered prosthetics to dynamically respond to the wearer’s environment and help amputees walk. Wearers of the robotic leg could walk on a treadmill almost as fast as an able-bodied person.

Researchers develop a system to reconstruct grape clusters in 3D, assess quality

Thu, 12/04/2014 - 15:30
Software to help reconstruct grape clusters with three-dimensional computer vision techniques has been developed by scientists. The system helps to automatically assess different parameters that define the quality of the wine grape during harvest time.

Milestones in human-machine cooperation

Thu, 12/04/2014 - 14:11
Major technical progress has been made on several fronts with the Robo-Mate exoskeleton. A key focus of the initial twelve months of the Robo-Mate project was to define the various production processes of end-users from different industries (e.g. automotive, automotive components, dismantling, and scrap recycling).

The future of work: More digital piecework, less job security

Thu, 12/04/2014 - 14:11
The rapid advance of digital technology has huge repercussions for the future of work. An economist calls for a new regulatory framework that addresses the ongoing changes in the working environment.

Computer-based approach to treating anxiety may reduce suicide risk

Wed, 12/03/2014 - 21:10
A group of psychology researchers has developed a simple computer-based approach to treating anxiety sensitivity, something that could have major implications for veterans and other groups who are considered at risk for suicide. "We have been using computer-delivered interventions for many years now in an effort to more efficiently deliver effective treatments," said a psychology professor. "This study gives us evidence that a brief intervention may help to prevent suicide risk."

Check less to reduce email stress

Wed, 12/03/2014 - 19:26
Is your inbox burning you out? Then take heart -- research suggests that easing up on email checking can help reduce psychological stress. Some of the study's 124 adults -- including students, financial analysts medical professionals and others -- were instructed to limit checking email to three times daily for a week. Others were told to check email as often as they could (which turned out to be about the same number of times that they normally checked their email prior to the study).

Volunteers can now help scientists seek Ebola cure in their (computer's) spare time

Wed, 12/03/2014 - 19:24
Beginning today, anyone can download a safe and free app that will put their computer or Android-based mobile device to work to form a virtual supercomputer to help scientists screen millions of chemical compounds to identify new drug leads for treating Ebola.

World’s fastest 2-D camera, 100 billion frames per second, may enable new scientific discoveries

Wed, 12/03/2014 - 19:24
A team of biomedical engineers has developed the world’s fastest receive-only 2-D camera, a device that can capture events up to 100 billion frames per second.

Clothes that can monitor, transmit biomedical info developed

Wed, 12/03/2014 - 17:51
Smart textiles are able to monitor and transmit wearers' biomedical information via wireless or cellular networks, developers report. This technological breakthrough clears a path for a host of new developments for people suffering from chronic diseases, elderly people living alone, and even firemen and police officers.

Extraordinary throughput at supercomputing conference

Wed, 12/03/2014 - 17:48
Computer scientists moved 65 terabytes of data in under just 100 minutes at a recent supercomputing conference.

Fractal geometry: Finding the simple patterns in a complex world

Wed, 12/03/2014 - 16:12
A mathematician has developed a new way to uncover simple patterns that might underlie apparently complex systems, such as clouds, cracks in materials or the movement of the stockmarket. The method, named fractal Fourier analysis, is based on new branch of mathematics called fractal geometry. The method could help scientists better understand the complicated signals that the body gives out, such as nerve impulses or brain waves.

More Hispanics earning bachelor’s degrees in physical sciences and engineering

Wed, 12/03/2014 - 16:07
The number of Hispanic students receiving bachelor’s degrees in the physical sciences and engineering has increased over the last decade or so, passing 10,000 degrees per year for the first time in 2012. The overall number of U.S. students receiving degrees in those fields also increased over the same time, but it increased faster among Hispanics.
