Science Bulletins: Monitoring Mount Etna -- Magma on the Move
cientists in Sicily are collecting an enormous amount of data to monitor moving magma inside Mount Etna, one of the most active volcanoes in the world. Nearly a million people live on the volcano's flanks, so being able to predict an eruption could be a matter of life and death. In this Earth Bulletin, visit the volcano's snowy slopes and learn how scientists from the Italian National Institute for Geophysics and Volcanology record seismic activity, measure gases seeping up through the ground, s
Science Bulletins: Yellowstone: Monitoring the Fire Below
Three of the most catastrophic volcanic eruptions in geologic history occurred at a place now visited by nearly four million people a year: Yellowstone National Park. The magma chamber responsible still lies beneath, and continues to steam, heat, and shift the park landscape. Science Bulletins talks with the geologists regularly monitoring these disquieting signals to understand where this active region lies in its volcanic life span.
Science Nation - Metal Foam
By: nsf New material absorbs seven to eight times the energy absorbed by similar foams. Mechanical and aerospace engineering professor Afsaneh Rabiei set out to make a material as light as aluminum and stronger than stainless steel. Her goal was to create something that could be used in products that would save lives, save energy and eventually save money, all at the same time.

When Tennyson is describing how Tithonus feels he is most probably describing his own feelings of desolation since his dear friend Arthur Hallam died of a stroke at the age of
