Folks in Chatham should read this Scientific American article about the problem of abandoned uranium mines. When some of their mines ceased to be profitable 20 years ago, Tronox (née Kerr-McGee) just up and left, abandoning their mines. Folks living in the area are terribly sick, their very homes are radioactive, and radioactivity levels at the site are so high that their off the scale of the EPA's geiger counters. It'll cost hundreds of millions to clean up. It's great to ask what Virginia Uranium is going to do to make the Coles Hill mine safe while they're there, but what are they going to do to make it safe once they're done? Is it possible to make them post a bond for the life of the mine that will cover the cost of closing down the mine safely?
A mother tracked every time that her newborn son woke and slept for the first year of his life. The resulting chart is really interesting. It takes about eight months for a baby's sleep patterns to become (relatively) consistent and well-defined. The first couple of months is just a mess—there's just no forecasting when it'll be awake and when it'll be asleep.
Usually, art created by prehistoric cultures has faded with time. Lascaux's vivid colors were lost due to exhaled CO2. Ancient Greek and Roman sculptures have lost their paint—we admire white, smooth marble, not the brightly painted works that they were created as. But aboriginal rock art in Western Australia looks as good as it ever did, some 40,000 years after it was created. That's because it was made with paint impregnated with fungi that constantly renews itself. Bajillions of bacterial generations later, it's as fresh as it was when it painted.
