Scientists got a surprise recently when a team of physical chemists at Stanford University studied a common hydrogen reaction. Scientists got a surprise recently when a team of physical chemists at ... Continue reading
A New Twist on Fiber Optics
By twisting fiber optic strands into helical shapes, researchers have created unique structures that can precisely filter, polarize or scatter light. Compatible with standard fiber optic lines, these ... Continue reading
Distant Mountains Influence River Levels 50 Years Later
Rainfall in the mountains has a major influence on nearby river levels, and its effects can be seen as much as 50 years after the rain has fallen, according to hydrologists funded by the National ... Continue reading
Arctic Carbon a Potential Wild Card in Climate Change Scenarios
The Arctic Ocean receives about 10 percent of Earth's river water and with it some 25 teragrams [28 million tons] per year of dissolved organic carbon that had been held in far northern bogs and other ... Continue reading
Searing Heat, Little Package
Engineers have created a miniature hotplate that can reach temperatures above 1100C (2012F), self-contained within a 'laboratory' no bigger than a child's shoe. The micro-hotplates are only a few ... Continue reading
