Clusters of aluminum metal atoms become superconductive at surprisingly high temperatures Posted: 25 Feb 2015 10:22 AM PST Clusters of atoms known as 'superatoms' represent an entirely new family of superconductors -- one that appears to work at temperatures well above standard superconductors.

Parkinson's disease patients have reduced visual contrast acuity Posted: 25 Feb 2015 09:27 AM PST An iPad® application has been developed that can help physicians screen for Parkinson's Disease, report researchers. Patients with Parkinson's disease (PD) often have difficulties with visual acuity in low-contrast images. Because they may have normal high-contrast vision, this is often overlooked during routine eye exams, but this new app can help to identify the problem.

When it comes to the digital playground we need to stop crying wolf Posted: 25 Feb 2015 08:42 AM PST Kids are leading the transition to digital media today. But, while too much time online could cause developmental problems, media consumption habits may not be making our children less bright or sociable, after all.

Uncertainties must be taken into account in fisheries stock assessment Posted: 25 Feb 2015 06:41 AM PST Fisheries stock assessment provides information on the status of fish stocks and the impact of fishing on stock development. Since no direct information on fish stock size or fishing mortality rates is available, any conclusions are based on indirect information and the combination of various information sources. By applying new mathematical methods, the uncertainties related to fisheries stock assessment can be taken into account, thus providing more reliable assessments to support decision-making.

Novel computer model designed to understand cardiovascular diseases Posted: 25 Feb 2015 05:25 AM PST A novel three-dimensional, multiscale and multicomponent model of endothelial cells monolayer, the inner lining of artery, has been developed by researchers to identify the cellular mechanisms involved in cardiovascular diseases (CVD). New research based on the model is able to identify the main cellular pathways involved in the initiation and progression of the disease.
