Could Small Springs Beat Batteries?

MIT scientists have found that carbon nanotubes could be formed into tiny springs capable of storing as much energy, pound for pound, as the best lithium-ion batteries - potentially more durably and reliably.

Will electric vehicles finally take off?

This week’s question concerns electric vehicles. For decades, electric vehicles have been touted as the solution to zero emissions motoring. However, costly batteries and the lack of a supporting infrastructure have stunted electric vehicle development. U.S. and offshore automakers continue to step up electric vehicle development, and some say they expect limited production electric cars to emerge in the next few years. What do you think? Will electric vehicles finally take off? Yes or no?

A Natural Clean-Up Technology

Researchers at North Carolina State University are demonstrating that trees can be used to degrade or capture fuels that leak into soil and ground water. Through a process called phytoremediation, plants and trees remove pollutants from the environment or render them harmless.

Algae Blooms Broaden Battery Possibilities

Blooms of Cladophora algae may be troublesome, but they do have a positive side. Researchers at the Ångström Laboratory of Sweden's Uppsala University have discovered that the cellulose nanostructure of these algae can serve as an effective coating substrate for use in environmentally friendly batteries.

Tree Totally Powers Custom Circuit

Last year, MIT researchers found that plants generate a voltage of up to 200 millivolts when one electrode is placed in a plant and the other in the surrounding soil. A University of Washington team followed up on this research, and has run a custom circuit entirely off tree power.

Are you worried about contracting swine flu?

This week's question concerns swine flu. According to a recent report prepared by the President's Council of Advisors on Science and Technology, the H1N1 flu virus, commonly called swine flu, could infect anywhere from 30 to 50 percent of the U.S. population during the fall and winter months. In a worst-case scenario, the virus could cause anywhere from 30,000 to 90,000 fatalities, primarily among children and young adults. Although an H1N1 vaccine is being prepared, it is not expected to be available until mid-October, which some experts say could be too late. So we're curious - are you worried about contracting swine flu?
