A region of high heat flow in the
Earth's crust is described in the
September 4 issue of NATURE. Such
"hot spots", it says, may soon be
tapped as sources of geothermal
power.
The issue also contains an article
nuclear explosions and ozone. It
says that if anyone was foolish
enough to start a nuclear war, the
resulting destruction of the ozone
layer could make Earth uninhabitable.
