OCT may speed detection of pneumonia-related bacteria in ICU patients
Hospital medical staff may soon be able to more quickly visualize the presence of biofilm in endotracheal tubes, lessening the risk of ventilator-associated pneumonia, reports a new article the Journal of Biomedical Optics. Researchers have demonstrated that demonstrated that optical coherence tomography (OCT) can be used to determine the presence of biofilm, providing an alternative to methods requiring arduous sample preparation.

NSF CAREER award for electrically conducting polymer research
Dr. Yu Zhu at University of Akron is the recipient of a prestigious NSF CAREER Award. Zhu was awarded $538,679 for his five-year project involving the study of new types of conjugated polymers that have fused sites along their molecules, enabling hydrogen bonding. 'Understanding and controlling molecular packing in electrically conducting polymers could lead to the design of high-performance polymer electronics, which is important for applications requiring flexible, light and economical electronic materials,' says Zhu.

Students with influence over peers reduce school bullying by 30 percent
Curbing school bullying has been a focal point for educators, administrators, policymakers and parents, but the answer may not lie within rules set by adults, according to new research led by Princeton University. Instead, the solution might actually be to have the students themselves, particularly those most connected to their peers, promote conflict resolution in school.

Map shows hotspots for bat-human virus transmission risk
West Africa, sub-Saharan Africa and South East Asia are most at risk from bat viruses 'spilling over' into humans resulting in new emerging diseases, according to a new global map compiled by scientists at UCL, the Zoological Society of London (ZSL) and the University of Edinburgh. The map shows risk levels due to a variety of factors including large numbers of different bat viruses found locally, increasing population pressure, and hunting bats for bushmeat.

Tiniest chameleons deliver most powerful tongue-lashings
A new study reports one of the most explosive movements in the animal kingdom: the mighty tongue acceleration of a chameleon just a couple of inches long. The research illustrates that to observe some of nature's best performances, scientists sometimes have to look at its littlest species.

Improving accuracy in genomic mapping with time-series data
Researchers at the University of Minnesota and BioNano Genomics have improved a nanochannel-based form of mapping by using dynamic time-series data to measure the probability distribution, or how much genetic material separates two labels, based on whether the strands are stretched or compressed. They detail their work this week in Biomicrofluidics.

Researchers find that in race stereotypes, issues are not so black and white
Recent race-related events in Ferguson, Mo., St. Louis, Baltimore, Chicago, Charleston, S.C., and New York City -- all point to the continuing need to study and understand race relations in modern America. These events show how race and stereotypes are intertwined and can lead to explosive situations and protests. Now, three Arizona State University researchers have approached this problem by asking, why do white Americans' stereotypes of black Americans take the particular forms they do?

Carnegie Mellon develops new method for analyzing synaptic density
Carnegie Mellon University researchers have developed a new approach to broadly survey learning-related changes in synapse properties. In a study published in the Journal of Neuroscience, the researchers used machine-learning algorithms to analyze thousands of images from the cerebral cortex. This allowed them to identify synapses from an entire cortical region, revealing unanticipated information about how synaptic properties change during development and learning.
