Impact of patient-to-physician messaging reviewed in study

Fri, 10/10/2014 - 19:49
While it may take time before it’s known what impact email exchanges might have on patients and their care, a new study offers some early insights into the effects on doctors, suggesting that reimbursement models and physician workflow may need to adjust to accommodate message management.

Flying robots to save lives in the Alps

Fri, 10/10/2014 - 12:40
Scientists at the University of Twente are working on robots that are expected to save lives in calamity situations in the Alps. The emphasis within this SHERPA project is on cooperation between human rescue workers, the ground robot (‘ground rover’) with a robotic arm and flying robots.

Detecting depressive states in elderly with on-line monitoring devices

Thu, 10/09/2014 - 20:36
Detecting depression in older adults through monitoring their daily routine has become a reality thanks to a new system developed by researchers. This technology can be used as an auxiliary tool for the care of elderly people, who for various reasons, such as family abandonment of or a chronic condition, tend to fall into a depressed state.

Does Facebook make you lonely?

Thu, 10/09/2014 - 20:34
Existing research on the impact of Facebook on loneliness has been examined in a recent study. The conclusion: Facebook didn't make people lonely, but lonely people were more likely to use the popular social media site.

Launch of new sensor device on Hudson River set to 'wire' river for cleaner water

Thu, 10/09/2014 - 20:33
In the race to find solutions to critical water issues, the launch of a new cost-effective water quality sensor device is the first step in overcoming hurdles of historically prohibitive costs for long-term water resource monitoring, scientists say.

Dissolvable silicon circuits and sensors

Thu, 10/09/2014 - 19:38
Electronic devices that dissolve completely in water, leaving behind only harmless end products, are part of a rapidly emerging class of technology. This technology suggest a new era of devices that range from green consumer electronics to ‘electroceutical’ therapies, to biomedical sensor systems that do their work and then disappear.

Sculpting costumes with 3-D printers is 'the way theater is headed,' say theater education experts

Thu, 10/09/2014 - 19:38
Three-dimensional printers, which already have churned out toys, prosthetic limbs and one functional car, are taking the stage — literally -- in live theater. The new technology aids speed, creativity, flexibility -- and can satisfy directors who change plans midstream, says a former Disneyland costume designer.

Tumor segmentation software receives 510k clearance from FDA

Thu, 10/09/2014 - 18:15
New imaging software that facilitates 3-D lung tumor segmentation has been incorporated into the Smart Segmentation® module of Varian’s Eclipse™ treatment planning system and has received FDA 510k clearance.

Snakes and snake-like robots show how sidewinders conquer sandy slopes

Thu, 10/09/2014 - 18:14
The amazing ability of sidewinder snakes to quickly climb sandy slopes was once something biologists only vaguely understood and roboticists only dreamed of replicating. By studying the snakes in a unique bed of inclined sand and using a snake-like robot to test ideas spawned by observing the real animals, both biologists and roboticists have now gained long-sought insights.

Computer science: 'Data smashing' could unshackle automated discovery

Thu, 10/09/2014 - 16:56
Computing researchers have come up with a new principle they call 'data smashing' for estimating the similarities between streams of arbitrary data without human intervention, and without access to the data sources.

Gene that drives aggressive brain cancer found by new computational approach

Thu, 10/09/2014 - 16:49
Using an innovative algorithm that analyzes gene regulatory and signaling networks, researchers have found that loss of a gene called KLHL9 is the driving force behind the most aggressive form of glioblastoma, the most common form of brain cancer.

The mathematics behind the Ebola epidemic

Thu, 10/09/2014 - 14:09
Researchers have calculated new benchmark figures to precisely describe the Ebola epidemic in West Africa from a mathematical perspective. Their results may help health authorities to contain the epidemic.

More efficient transformer materials

Thu, 10/09/2014 - 13:17
Almost every electronic device contains a transformer. An important material used in their construction is electrical steel. Researchers have found a way to improve the performance of electrical steel and manufacture it more efficiently, using an optimized laser process.

Miniature camera may lead to fewer accidents

Thu, 10/09/2014 - 13:17
Measuring only a few cubic millimeters, a new type of camera module might soon be integrated into future driver assistance systems to help car drivers facing critical situations. The little gadget can be built into the vehicle without taking up space. The way it works is particularly reliable, thanks to its special encapsulation.

Mining big data yields Alzheimer's discovery

Thu, 10/09/2014 - 13:17
A new way of working to identify a new gene linked to neurodegenerative diseases such as Alzheimer’s has been used by researchers. The discovery fills in another piece of the jigsaw when it comes to identifying people most at risk of developing the condition.

Engineering new, efficient vehicle powertrains

Thu, 10/09/2014 - 13:16
Car engines -- whether driven by gasoline, diesel, or electricity -- waste an abundance of energy. Researchers are working on ways to stem this wastefulness. Ultramodern test facilities are helping them to optimize the entire development process of the engine. In the laboratory, they have already raised the degree of efficiency by up to ten percent.

Online intervention tool for physician trainees may improve care of patients with substance use disorders

Thu, 10/09/2014 - 00:35
Online learning interventions and small group debriefings can improve medical residents’ attitudes and communication skills toward patients with substance use disorders, and may result in improved care for these patients, according to a new study.

Reproducibility score for SNPs associated with human disease in GWAS

Wed, 10/08/2014 - 19:36
Nine traits that are not dependent on P values to predict single nucleotide polymorphisms reproducibility in genome-wide association studies and reduce false positives have been identified by researchers. Te empirical model can be used to select SNPs for validation and prioritization, one expert said.

Mind-controlled prosthetic arms that work in daily life are now a reality

Wed, 10/08/2014 - 19:36
For the first time, robotic prostheses controlled via implanted neuromuscular interfaces have become a clinical reality. A novel osseointegrated (bone-anchored) implant system gives patients new opportunities in their daily life and professional activities.

International collaborations produce more influential science, analysis finds

Wed, 10/08/2014 - 18:09
A new analysis calculating the scientific impact of 1.25 million journal articles finds that papers with authors from multiple countries are cited more often and more likely to both appear in prestigious journals, and provides a new perspective on the changing global landscape of scientific influence.
