Lupins produce colourful blossoms and nutritious beans. Just how these plants draw water has now for the first time been observed in three dimensions by a University of Potsdam team at the HZB-BER II neutron source in Berlin. They improved the temporal resolution of neutron tomography more than onehundred-fold and obtained a detailed 3D image every ten seconds. This ultrafast neutron tomography is suitable as well for analyses of dynamic processes in other materials.
New research could help claypan farmers improve yields while saving costs.
A first test of humans' ability to modify clouds would help explain the behavior of clouds and aerosols, while also testing a possible future climate emergency measure.
Researchers writing in Microchemical Journal are bringing attention to the fact that commonly used antibiotic drugs are making their way out into the environment, where they can harm microbes that are essential to a healthy environment. Their review article has been selected for the Elsevier Atlas Award, which recognizes research that could significantly impact people's lives around the world or has already done so.
New research supports using different soil moisture measurement systems for more accurate wildfire risk assessment in Oklahoma and similar areas.
A University of Alaska Fairbanks study looking at the physics of tidewater glaciers has yielded new insights into what drives their retreat-and-advance cycles and the role that climate plays in these cycles.
Using a publicly available climate model, Berkeley Lab researchers 'hindcast' the conditions that led to the Sept. 9-16, 2013 flooding around Boulder, Colo. and found that climate change attributed to human activity made the storm much more severe than would otherwise have occurred.
Three new species of toads have been discovered living in Nevada's Great Basin in an expansive survey of the 190,000 square mile ancient lake bottom. 'We've found the toads in small, wet habitats surrounded by high-desert completely cut off from other populations,' Dick Tracy, renowned biology professor at the University of Nevada, Reno, said. 'These are absolutely new, true species that have been separated from other populations for 650,000 years.'
Studies of naturally carbonated mineral water have given scientists insight on how to locate hot water springs -- potential sources of sustainable geothermal energy.
Small mountain glaciers play a big role in recharging vital aquifers and in keeping rivers flowing during the winter, according to a new study published in Geophysical Research Letters, a journal of the American Geophysical Union. The study also suggests that the accelerated melting of mountain glaciers in recent decades may explain a phenomenon that has long puzzled scientists -- why Arctic and sub-Arctic rivers have increased their water flow during the winter even without a correlative increase in rain or snowfall.
