Researchers at Stanford University have completed the first quantitative, scientific comparison of alternative energy solutions by assessing not only their potential for delivering energy for electricity and vehicles, but also their impacts on global warming, human health, energy security, water supply, space requirements, wildlife, water pollution, reliability and sustainability. Based on their model, they found that the best sources of alternative energy are wind, concentrated solar, and geothermal energy. The worst are nuclear, clean coal, and ethanol-based fuels.

Stanford researchers have found that voters are subconsciously swayed by candidates who share their facial features. In three experiments, researchers at the Virtual Human Interaction Lab worked with cheap, easy-to-use computer software to morph pictures of about 600 test subjects with photos of politicians. And they kept coming up with the same results: For the would-be voters who weren't very familiar with the candidates or in perfect lockstep with their positions or political parties, the facial similarity was enough to clinch their votes.

A team of scientists at Stanford University has tracked the movement of carbon nanotubes through the digestive system of mice. They've determined that the nanotubes are expelled and do not exhibit any toxicity in the mice. As a result, the study paves the way toward future applications of nanotubes in the treatment of cancer and tumor. Previous research by the same team demonstrated that nanotubes can be used in cancer treatments. Nanotubes can be used to destroy cancer cells in two ways. One method involves shining light on the nanotubes, which activates the nanotubes and generates heat to destroy cancer cells. Another method involves attaching medicine to the nanotubes, which are able to accurately "find" cancerous cells without impacting healthy cells.
