...Scientists have identified the defective gene that causes Wilson's disease, a disorder that destroys the liver and brain. The gene prevents the liver from removing the excess copper that enters the body in food; eventually, the metal hurts the liver and leaks into the brain. The finding could lead to a screening test and more effective treatment...
...mining industry sees nothing outlandish in the risk Crown Butte proposes to take with the nation's oldest national park, and nothing funny about the claiming of ski runs by environmental jokers. Hard-rock mining (for gold, copper, silver and other metals) once ruled the Rocky Mountain states. The industry is foreign-dominated now (18 of the 25 largest gold mines in the country are owned by non-U.S. firms, most of them Canadian). Only one Western job in 1,000 is directly tied to metal mining. But mining interests have not lost the knack of command, nor have...
...biggest problem here and throughout the Rockies is acidic drainage. Gold-bearing rock tends to contain large quantities of sulfur, which form sulfuric acid when exposed to air and water. The acid puts such highly toxic metals as copper and cadmium into solution, and the poisons kill aquatic life. That happened before when Henderson was mined...
...create superconductors --those almost magical materials that allow electricity to flow through them with no resistance whatsoever. When scientists get the temperature high enough, superconductors could, among other wonderful things, make computers more powerful, turn electric cars practical and improve energy efficiency by offering a superior alternative to copper wiring. At stake in this competition is far more gold than the Olympic judges could ever award...
...some cases the flashing, the layer of material between a building's outer walls and inner walls used to keep out precipitation, has deteriorated. While all flashing wears down over time, most of the older buildings used more durable materials, usually lead-coated copper, that lasts for about 100 years, says Michael N. Litton, acting director of the Office of Physical Resources...
