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?

Should there be an airline “passenger bill of rights”?

This week’s question concerns the rights of airline passengers. Several recent incidents of airline passengers being stranded on planes for up to six hours may have strengthened the case for a “passenger bill of rights” pending in Congress. The bill would require stranded planes to return to the terminal after a certain amount of time, and mandate that airlines improve customer service measures such as providing food and water during long delays and establish a customer complaint hotline. Air carriers argue such measures would only increase runway congestion and flight cancellations, further infuriating passengers.

What do you think? Should there be an airline “passenger bill of rights”? Yes or no?
