Jupiter's Radio Storms
Jupiter's intense storms, occurring near the planet's magnetic poles, create radio waves that travel all the way to Earth. Ham radio operators have been listening to the sounds, in the 18 to 32 MHz range, and now you can too. NASA is providing streaming audio from the University of Florida's Radio Observatory, that's been listening to Jupiter. You may hear overlapping music and voices from terrestrial radio stations that interferes with the radio waves coming from Jupiter. Check out the NASA site for more information on this really cool phenomena!
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...
