Sangay Volcano Erupts in Ecuador

This past December, our team trekked up a remote, active volcano in Ecuador known as Sangay, “The Giver.” We collected more than 60 geologic samples from lava flows and rocks all up and down the slopes, which will help us better understand the working of this and other volcanoes around the world.

One month after we departed, Sangay started erupting with ferocity again. This renewed activity, first detected by airline pilots, was captured in photographs from the Macas, Ecuador region and has been imaged by satellite, all seen below.

According to MIROVA (Middle InfarRed Observation of Volcanic Activity), which looks at MODIS (Moderate Resolution Imaging Spectroradiometer) data aboard the Terra EOM and Agua EOS satellites, since January 15, 2015, there has been detectable thermal activity at the summit of Sangay, with a multitude of thermal alerts with significant radiant heat emitting from its summit region (spanning from 1 to 10 MW). Significantly, at 03:20 (UTC) on Jan 26, 2015, a thermal anomaly of 75 —> Read More Here

Caging of molecules allows investigation of equilibrium thermodynamics

High performance materials for gas storage, thermal insulators or nanomachines need a thorough understanding of the behavior of the material down to the molecular level. Thermodynamics, which have been developed two hundred years ago to increase the efficiency of steam engines, typically observes and averages over a large number of molecules. Now a team of scientists has developed a methodology, to investigate the equilibrium thermodynamics of single molecules. —> Read More Here
