The Stuxnet worm and other covert measures appear designed to slow Iran's progress toward a nuclear bomb. But US 'miscalculations' could raise the likelihood of a costly showdown, some experts warn.
Although the threat to Los Alamos and the nation's premier nuclear research lab has passed, the mammoth wildfire raging in northern New Mexico still threatens sacred sites of American Indian tribes.
New Mexico fires entered the property of a nuclear facility in Los Alamos, Monday.
The circle of seismic activity in the Pacific Ocean, known as the "ring of fire," stretches from Australia to Russia around to Alaska and America's West Coast and down to Chile in South America. It's an area responsible for 90 percent of the world's earthquakes and 75 percent of its volcanoes. So which of the more than 26 nations in the ring has nuclear power? Only three: Japan, of course (more than 50 plants); the United States (eight reactors at four plants); and Mexico (two reactors at one plant). Here's a look at the five non-Japanese plants in the world's most active earthquake zone:
From establishing cyberwar limitation treaties to banning the 'first use' of cyberweapons, experts offer ways to head off a future major conflict in cyberspace.
Samples taken from the US site of the Trinity atomic bomb test allow scientists to better understand how to track the source of a detonated nuclear weapon.
The site of the world's first nuclear detonation, code named 'Trinity,' is seen 0.016 seconds after the explosion on July 16, 1945. The effort to build a bomb during World War II, called the Manhattan Project, led by physicist J. Robert Oppenheimer was begun in 1941.
