Fuel Made by Sun, Water, Carbon Dioxide, and Nanotechnology
Trees use sunlight to forge carbon dioxide and water into a useful fuel. It is an elegantly simple strategy, using renewable energy and common non-toxic elements that has worked for millions of years. Why don’t we do the same thing,

Harnessing Molecular Motors: Nanotechnology and Biology Meet to Redefine 'Lab on a Chip'
If the electric Mini can have motors in its wheels why can't science geeks get molecular motors in their labs? After graduating college I spent a good three years of my life moving small volumes of fluid from one tube to another,
