Name That Species
Extremophiles are microbes
that have adapted to extreme
environments, such as Utah's
Great Salt Lake. But new
microorganisms can be found
in everyday places, and
scientists are showing
school kids how to discover

Scum-Free Fish Tank
Chemical engineers developed
a pump that splits into two
pieces, a propeller for the
interior of the aquarium and
a motor for the exterior,
connected across the glass
wall by strong magnets. The
magnet is made of neodymium,
