Microscopic defects in ice influence how massive glaciers flow, study shows
As they seep and calve into the sea, melting glaciers and ice sheets are raising global water levels at unprecedented rates. To predict and prepare for future sea-level rise, scientists need a better understanding of how fast glaciers melt and what i.....»»
From ashes to alerts: Science helps protect Colorado travelers
In the summer of 2021, travelers in Colorado's Glenwood Canyon were safely evacuated before massive mounds of mud and rocks buried highways and destroyed bridges, thanks to a debris flow warning system developed in part by the U.S. Geological Survey......»»
Speeding up calculations that reveal how electrons interact in materials
Materials scientists and engineers would like to know precisely how electrons interact and move in new materials and how the devices made with them will behave. Will the electrical current flow easily within the material? Is there a temperature at wh.....»»
Producing gold nano-particles (and hydrogen) in water without the need for toxic chemicals
In a surprise discovery, Flinders University nanotechnology researchers have produced a range of different types of gold nanoparticles by adjusting water flow in the novel vortex fluidic device—without the need for toxic chemicals. The article, "Na.....»»
