Just like adults, children as young as 3 tend to judge an individual's character traits, such as trustworthiness and competence, simply by looking at the person's face, new research shows. And they show remarkable consensus in the judgments they make, the findings suggest.

The research, led by psychological scientist Emily Cogsdill of Harvard University, shows that the predisposition to judge others based on physical features starts early in childhood and does not require years of social experience. The study is published in Psychological Science, a journal of the Association for Psychological Science.

Many breast cancer survivors experience fatigue and other debilitating symptoms that persist months to years after their course of treatment has ended.

Now researchers at the Winship Cancer Institute of Emory University have found clues that may explain how these symptoms can linger. Chemotherapy, one of the major treatments for breast cancer, can leave a long-lasting epigenetic imprint in the DNA of breast cancer patients' blood cells. That imprint is associated with biological signs of inflammation up to six months after the completion of treatment. Inflammation in turn is believed to cause symptoms like fatigue.

The findings are now published online in the journal Brain, Behavior and Immunity.

The ice-free season across the Arctic is getting longer by five days per decade, according to new research from a team including Prof Julienne Stroeve (UCL Earth Sciences). New analysis of satellite data shows the Arctic Ocean absorbing ever more of the sun's energy in summer, leading to an ever later appearance of sea ice in the autumn. In some regions, autumn freeze-up is occurring up to 11 days per decade later than it used to.

The research, published in a forthcoming issue of the journal Geophysical Research Letters, has implications for tracking climate change, as well as having practical applications for shipping and the resource industry in the Arctic regions.

Decades ago, when the Outcome Based Education movement was trying to take hold, educators who were already overburdened did not want to be saddles with managing social and emotional development of diverse classrooms and the competing goals of parents.

Parents agreed that turning over the social development of children to school districts was a bad idea but a new paper says that classroom programs designed to improve elementary school students' social and emotional skills also increase reading and math achievement, even if academic improvement is not a direct goal of the skills building. The benefit holds true for students across a range of socio-economic backgrounds, they say.

According to the results of a recent study, soil color changes in the atmosphere basically through the oxidation of chemical substances in the soil. The fundamental mechanism is the remodeling effect of micro-structures because of motion effects and chemical reactions of the water–soil–electrolyte–atmosphere system leading to the coupling and transforming of soil particles. The above provides a theoretical foundation for the assessment and forecast of the stability of the geotechnical environment.

COLUMBIA, S.C. — Dispersants are often used in oil spill responses because they may mitigate the environmental impacts of the spill by moving the oil from the water surface into the water column enhancing its biodegradation. While this process helps reduce the likelihood of oil exposure to marine wildlife such as seabirds and marine mammals, aquatic toxicity on marine communities from the dispersant and the chemically dispersed oil needs to be considered more carefully.
