A new study has found that 5- to 6-year-olds view people's environments, not their skin color, as the most important determinant of their behavior and psychological characteristics. These findings contradict the idea that views of race that are known to lead to prejudice such as believing that race naturally divides the world into distinct kinds of people's inevitably develop early in childhood.

Surprisingly, cloudy, gray and humid winter days can actually cause the snowpack to warm faster, increasing the likelihood of melt during winter months when the snowpack should be growing, the authors report. In contrast, under clear skies and low humidity the snow can become colder than the air, preserving the snowpack until spring.

Sea turtle crisis: Moisture, not just heat impacts sex of sea turtle hatchlings  

Male sea turtles are disappearing and not just in Australia. Researchers found that 97 to 100 percent of hatchlings in southeast Florida have been female since 2002. They are the first to show why and how moisture conditions inside the nest in addition to heat affect the development and sex ratios of turtle embryos, using a novel technique they developed to estimate sex ratios with a male-specific, transcriptional molecular marker Sox9.

Two-dimensional circuit with magnetic quasi-particles  

Whether smart phone, computer or dialysis machine -- there is no electronic device without chips and their electronic components inside. The individual circuit elements are therefore often wired using three dimensional so called bridge constructions. Physicists are now working on a more efficient variation, where specific quasiparticles named magnons instead of electrons are being used. They have shown for the first time, in an initial model, that magnon current flow is possible in an integrated
