Gathering of Planets
On March 22nd, if you find some clear skies after sundown, you're in for a show that doesn't happen very often. Mercury, Venus, Mars, Saturn and Jupiter will all be in the sky, and they will all be viewable by eye. This won't happen again until 2008, so if you miss it, you've got four years to wait. Check out the NASA site for the best viewing times, and where to look.

Richard Wrangham of Harvard believes there's more to cooking than evolutionary history would have you believe. Wrangham points out that there is no way homo sapiens could survive on just raw food. Raw food just doesn't give up calories as easily as cooked food -- and raw food makes the digestive system expend more energy to get at those calories. Cooking on the other hand breaks complex molecules down, allowing the digestive system to make easy work of them -- and cooking also softens food, allowing the body to get to the calories with less effort...
