Living Machines
The goal of bio-mechanical research has always been on totally artifical organs - afterall, that's where the glory is - being able to developed a completely artificial heart, or lung, or whatever other critical organ to keep us going. How about an intermediate step however? A cyborb organ if you will? Well, Univeristy of Michigan internist, David Humes, has done just that - he's managed to create a bioartificial kidney - a pastic device packed with kidney cells, that in clinical trials, is showing some promise.

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...
