How processes below a volcano are linked to seismic signals at the surface is described by scientists from the petrology group of the Ruhr-Universität Bochum and their colleagues from Bristol in a paper published today in Science. They analyzed the growth of crystals in the magma chamber and used results obtained from the monitoring of seismic signals. The research could ultimately help to predict future volcanic eruptions with greater accuracy.

Many people anticipating the creation of an invisibility cloak might be surprised to learn that a group of American researchers has created 25 000 individual cloaks.
But before you rush to buy one from your local shop, the cloaks are just 30 micrometres in diameter and are laid out together on a 25 millimetre gold sheet.

A forensic approach that links changes deep below a volcano to signals at the surface is described by scientists from the University of Bristol in a paper published today in Science. The research could ultimately help to predict future volcanic eruptions with greater accuracy.
Using forensic-style chemical analysis, Dr Kate Saunders and colleagues directly linked seismic observations of the deadly 1980 Mount St. Helens eruption to crystal growth within the magma chamber, the large underground pool of liquid rock beneath the volcano.

Science magazine has awarded a prize for Inquiry-Based Instruction to a Case Western Reserve University class that melds biology, computer modeling, mathematical analysis and writing.
"Dynamics of Biological Systems," taught by Biology Professor Hillel Chiel and three graduate assistants, abandons traditional lectures altogether in favor of learning by doing. The teachers call the class an example of the use of the continual improvement model in education.

GAINESVILLE, Fla. — Doping may be a no-no for athletes, but researchers in the University of Florida's physics department say it was key in getting unprecedented power conversion efficiency from a new graphene solar cell created in their lab.

CARNELIAN BAY, Calif. — Results of a new U.S. Geological Survey study conclude that faults west of Lake Tahoe, Calif., referred to as the Tahoe-Sierra frontal fault zone, pose a substantial increase in the seismic hazard assessment for the Lake Tahoe region of California and Nevada, and could potentially generate earthquakes with magnitudes ranging from 6.3 to 6.9. A close association of landslide deposits and active faults also suggests that there is an earthquake-induced landslide hazard along the steep fault-formed range front west of Lake Tahoe.
