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.

Newly developed liquid crystal elastomer material could enable advanced sensors
At Kent State University, Peter Palffy-Muhoray, Ph.D., associate director of the Liquid Crystal Institute and professor of chemical physics, has been collaborating with the world's experts in liquid crystal elastomers research. Recently, he and his graduate assistant along with colleagues from Japan's Kyoto Institute of Technology developed the first type of cholesteric liquid crystal elastomers with special properties that enable it to precisely emit laser light, without the use of mirrors, while being stretched.

Evergreens at risk
In a broad analysis of climate change scenarios, researchers see a grim future for evergreen forests in the Southwest region of the United States. Using field reports, validated regional predictions and computer models, they project a 72 percent loss of needleleaf evergreens by 2050, almost 100 percent by 2100.

TSRI and St. Jude scientists study single 'transformer' proteins with role in cancer
A new study led by scientists at the Scripps Research Institute and St. Jude Children's Research Hospital shows how a protein involved in cancer twists and morphs into different structures. This protein has many functions and, when mutated, has been shown to interfere with cells' normal tumor suppressing ability.

Workforce homogeneity limits creativity, discovery, and job satisfaction; nonetheless, eighty-one percent of US science, technology, engineering, and math (STEM) university faculty members are men. The relative dearth of women in the field is a long-recognized problem -- but it's one that may be on its way to a solution.

New research shows same growth rate for farming, non-farming prehistoric people
Prehistoric human populations of hunter-gatherers in a region of North America grew at the same rate as farming societies in Europe, according to a new radiocarbon analysis. The findings challenge the commonly held view that the advent of agriculture 10,000-12,000 years ago accelerated human population growth.

Protecting a few students from negative stereotypes benefits entire classroom
Interventions targeted at individual students can improve the classroom environment and trigger a second wave of benefits for all classmates, new research shows. The findings, published in Psychological Science, a journal of the Association for Psychological Science, indicate that sharing a classroom with greater numbers of students who participate in a brief intervention can boost all students' grades over and above the initial benefits of the intervention.
