Elizabeth Taylor's heart-shaped diamond known as the "Taj Mahal" is at the center of a legal squabble between the trustees of the glamorous actress' estate and Christie's auction house.

Founded in 1952, the mine is considered the first big strike in the burgeoning market for uranium, mostly to fuel the growing U.S. standoff with the Soviet Union.

An obstacle to greening L.A.'s energy portfolio is the DWP's contract with a Utah plant, which requires the city to buy coal power until 2027.

A settlement in last year's fatal West Virginia coal-mine explosion is welcome, but much more needs to be done to ensure the safety of America's miners.

The young miners descend on rickety ladders made of branches into the makeshift coal mines dotting Jaintia Hills in northeast India, scrambling sideways into “rat hole” shafts so small that even kneeling becomes impossible. Lying horizontally, they hack away with picks and their bare hands: Human labor here is far cheaper than machines. Many wear flip-flops and shorts, their faces and lungs blackened by coal. None has a helmet. Two hours of grinding work fills a cart half the size of a coffin that they drag back, crouching, to the mine mouth, where a clerk credits their work. Most earn a dollar or two an hour.
