An atomically thin material may lead to the thinnest-ever imaging platform. Synthetic two-dimensional materials based on metal chalcogenide compounds could be the basis for superthin devices.

Europe shows that humans and large predators can share the same landscape

Posted: 19 Dec 2014 10:01 AM PST

The recovery of large carnivores in Europe is a great success for nature conservation. At one third of mainland Europe, at least one species of large carnivore is present, according to a new article. It is an excellent example that humans and carnivores can share the same landscape, say researchers.

Signs of Europa plumes remain elusive in search of Cassini data

Posted: 18 Dec 2014 04:47 PM PST

A fresh look at data collected by NASA's Cassini spacecraft during its 2001 flyby of Jupiter shows that Europa's tenuous atmosphere is even thinner than previously thought and also suggests that the thin, hot gas around the moon does not show evidence of plume activity occurring at the time of the flyby. The new research provides a snapshot of Europa's state of activity at that time, and suggests that if there is plume activity, it is likely intermittent.

Early caregiving experiences have long-term effects on social relationships, achievement

Posted: 18 Dec 2014 05:13 AM PST

A new study has found that sensitive caregiving in the first three years of life predicts an individual's social competence and academic achievement, not only during childhood and adolescence, but into adulthood. The study used information from 243 individuals who were born into poverty, came from a range of racial/ethnic backgrounds, and had been followed from birth to age 32.

NASA data underscore severity of California drought

It will take about 11 trillion gallons of water (42 cubic kilometers) -- around 1.5 times the maximum volume of the largest U.S. reservoir -- to recover from California's continuing drought, according to a new analysis of NASA satellite data.
