How to Map a Lightning Strike   Some scientists literally spend
their time waiting for lightning to strike.  Volcano Lightning:
How Does It Happen? DNews Video  Lightning is the second highest
cause of annual weather-related deaths in the United States,
according to the National Weather Association. It starts fires,
causes power outages and wreaks havoc on electronics systems.
The science of lightning detection has improved dramatically
since Ben Franklin flew his kite in a thunderstorm in 1752.
Researchers can now predict conditions that precede a bolt from
the blue, and track the location and strength of a strike while
it's occurring.  "We've made significant progress in
understanding the physics of lightning, but there's still lot of
work that can be done," said atmospheric scientist Phillip
Bitzer of the University of Alabama in Huntsville.  Fall from
