Engineers find antioxidants improve nanoscale visualization of polymers
Reactive molecules, such as free radicals, can be produced in the body after exposure to certain environments or substances and go on to cause cell damage.
Cervone elected to lead AGU natural hazards section

Leaf fossils show severe end-Cretaceous plant extinction in southern Argentina
Fossil leaf assemblages from Patagonia, Argentina, suggest that vegetation in South America suffered great losses following an astroid impact but rebounded quickly.
Putting on the pressure improves glass for fiber optics
Researchers from Penn State and AGC Inc. in Japan suggest that the silica glass used for fiber optic cables would have less signal loss if it were manufactured under high pressure.
Deep, slow-slip action may direct largest earthquakes and their tsunamis
A team of geoscientists thinks the key to understanding some destructive earthquakes may lie in the deep, gradual slow-slip behaviors beneath the subduction zones.
