New 'chemical radar' among national security innovations in ACS podcast
Date:9/4/2008

of Global Challenges includes:

  • Development of an "optical fingerprinting" technique for early detection of smallpox, anthrax, and other bioterrorism agents. The device could be used in football stadiums, airports, shopping malls, areas where large numbers of people might be exposed to attacks.

  • A new rapid detection method for ricin, a dangerous plant toxin found in castor beans with no known antidote. With 100 million pounds of castor bean waste produced annually, a potential source of the toxin is readily available. The test detects minute quantities of castor bean DNA.

  • A rugged antibacterial coating made of carbon nanotubes coated with a natural microbe-fighting substance known as lysozyme that scientists long have dreamed of using to battle pathogens. The coating can be applied to a variety of surfaces, and withstands common household cleaners.

The podcasts are available without charge for listening on computers and downloading to portable digital audio devices at iTunes and other podcasting sites. They also can be accessed on ACS's Global Challenges web site. The site provides audio links and full transcripts of each podcast. Additional resources on each Global Challenges topic also are available, on the site, including information for consumers, students, and educators.

Other Global Challenges topics to date include:

  • Providing safe drinking water. Scientific advances promise to help almost 1.2 billion people in developing countries who lack access to pure water, and ensure safe water supplies for people in developed countries.

  • Fresh water from the sea. Almost 97 per cent of Earth's water is salty water in the oceans and brackish water inland. Advances in water desalination technology are making more of this water available for drinking, agriculture, and ind
