E-health vital in battle against heart disease say cardiology leaders

Tue, 08/25/2015 - 01:21
E-health is vital to winning the battle against heart disease, cardiology leaders said. The novel paper outlines how the ESC will exploit e-health in education and research, while tackling issues of quality control and data security.

Electronic trigger reduces delays in evaluation for cancer diagnosis

Tue, 08/25/2015 - 01:19
Electronic triggers designed to search for key data, developed by researchers at Baylor College of Medicine and Michael E. DeBakey Veterans Affairs Medical Center, were able to identify and reduce follow-up delays for patients being evaluated for a diagnosis of colon or prostate cancer.

Issues surrounding security tools for software developers

Mon, 08/24/2015 - 17:05
For software programmers, security tools are analytic software that can scan or run their code to expose vulnerabilities long before the software goes to market. But these tools can have shortcomings, and programmers don't always use them. New research tackles three different aspects of the issue.

The Rubik's Cube of economics

Mon, 08/24/2015 - 15:49
Like the Rubik's Cube, a three-dimensional combination puzzle where every twist also scrambles the face opposite of it, economics puzzles are similarly interlinked -- a change in policy may lead to repercussions elsewhere.

Autism: Transforming behavioral therapy with technology

Mon, 08/24/2015 - 15:47
Using computer vision, signal processing and privacy protection, a doctoral student, along with electrical and computer engineering professors, have developed "MEBook," a combination of a social narrative and gaming system that psychologists and parents can use as behavioral therapies for autistic children.

Who will develop psychosis? Automated speech analysis may have the answer

Mon, 08/24/2015 - 15:08
An automated speech analysis program correctly differentiated between at-risk young people who developed psychosis over a two-and-a-half year period and those who did not. In a proof-of-principle study, researchers found that the computerized analysis provided a more accurate classification than clinical ratings.

Smooth robot movements reduce energy consumption by up to 40 percent

Mon, 08/24/2015 - 10:49
By minimizing the acceleration of industrial robots, energy consumption can be reduced by up to 40 percent -- while retaining the given production time. This is the result of a new optimization algorithm.

Next gen electronics: Superlattice design realizes elusive multiferroic properties

Fri, 08/21/2015 - 18:17
With a new design that sandwiches a polar metallic oxide between insulating materials at the nanoscale, the resulting multiferroic superlattice could open the door for improved electronics.

Photon-based rather than electron-based computers? 'Magic' sphere for information transfer

Fri, 08/21/2015 - 17:16
A professor has made the 'magic' sphere for information transfer. In several years our computers, nanoantennas and other kinds of equipment will operate on the base of photons, rather than electrons. Even now we are practically prepared to accomplish this switch. If it happens, the spheres may become one of the elementary components of new photonic devices.

Novel nanostructures for efficient long-range energy transport

Fri, 08/21/2015 - 12:27
An interdisciplinary group of researchers report on nanofibers, which enable for the first time a directed energy transport over several micrometers at room temperature. This transport distance can only be explained with quantum coherence effects along the individual nanofibers.

How can we improve data sharing of biomedical research across the globe?

Fri, 08/21/2015 - 12:27
With the globalization of biomedical research and growing concerns about possible pandemics of diseases such as HIV, SARS, and Ebola, international data-sharing practices are of growing interest to the biomedical science community. A new special journal issue presents guidelines, protocols, models, and new resources to improve data sharing across the globe.

Ecologists roll a century's work on food-webs into a single model

Thu, 08/20/2015 - 18:47
A new model presents a common mathematical structure that underlies the full range of feeding strategies of plants and animals: from familiar parasites, predators, and scavengers to more obscure parasitic castrators and decomposers. Now ecologists can view all food-web interactions through the same lens using a common language to understand the natural world.

Cellphone data can track infectious diseases

Thu, 08/20/2015 - 17:47
Tracking mobile phone data is often associated with privacy issues, but these vast datasets could be the key to understanding how infectious diseases are spread seasonally, according to a study.

New, stable 2-D materials with revolutionary new properties

Thu, 08/20/2015 - 13:54
Newly developed 2-D crystals are capable of delivering designer materials with revolutionary new properties. By protecting the new reactive crystals with more stable 2D materials, such as graphene, via computer control in a specially designed inert gas chamber environments, these materials can be successfully isolated to a single atomic layer for the first time.

Social security, social safety

Thu, 08/20/2015 - 12:23
Security and safety could be improved if researchers from very disparate disciplines - humanities, computer science and politics - were to work together, according to new research. Moreover, such coordinated efforts online would improve crisis management during natural disasters, terrorist attack or cyber warfare.

Imaging software could speed up breast cancer diagnosis

Thu, 08/20/2015 - 01:11
New software could speed up breast cancer diagnosis with 90 percent accuracy without the need for a specialist, according to research. This could improve breast cancer management, particularly in developing countries where pathologists are not routinely available.

Activity trackers not as accurate for some activities

Wed, 08/19/2015 - 21:24
Activity trackers can provide a good overall estimate of calories burned, but a new study finds they're less accurate when measuring certain activities, such as strength training.

Supercomputers listen to the heart

Wed, 08/19/2015 - 16:07
New supercomputer models have come closer than ever to capturing the behavior of normal human heart valves and their replacements, according to recent studies. The studies focused on how heart valve tissue responds to realistic blood flow. The new models can help doctors make more durable repair and replacement of heart valves.

Algorithm interprets breathing difficulties to aid in medical care

Wed, 08/19/2015 - 14:36
Researchers have developed an efficient algorithm that can interpret the wheezing of patients with breathing difficulties to give medical providers information about what's happening in the lungs. The work is part of a larger, ongoing project to develop wearable smart medical sensors for monitoring, collecting and interpreting personal health data.
