Millions of years ago, fish in both northern and southern
polar waters adapted to a cooling climate by evolving
antifreeze proteins that kept them from freezing in

Safer Way to Monitor Volcanoes
Volcano expert Stanley Williams of Arizona State University
in Tempe barely survived an eruption that killed several
