Stardust Comet Encounter
Yesterday, NASA's Stardust spacecraft had a successful encounter with Comet Wild-2. The spacecraft was launched in 1999 with a mission to flyby Wild 2, obtain a sample of the comet, and return it to Earth. (NASA has a great press kit, that details the mission, etc.) The sample will touch down on January 15, 2006, at a US Air Force base in Utah, when Wild flies by Earth and drops its payload. I hope the NASA kids have a good, secure place to ready when they open that capsule -- I've seen movies!
The first chef
First came fire ... and then, as the camera shifts to the soon to be late-village idiot, you're left wondering -- just what was going through that mind -- and food is put on the fire, for the first time, and cooking is accidentally discovered by humanity. The first chef is ridiculed by grunts, then the local thug tries a sample of the burnt carcass, and soon, everybody gets queued at the McDonalds drive-thru. What happened? 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...
