I just finished an exhausting push to file 20 suggestions at SINCESLICEDBREAD.COM. (Twenty!) Go have a look.
Too tired of politics to post anything more on that depressing subject, I will pause to offer a few techie snippets. Thrive.
Cheap Chemical Sensors: Electronic "noses" made from printed electronics could detect toxic chemicals inexpensively.
Technology already exists that can sniff out chemicals in the air and water -- but the detecting devices are expensive, limiting their use. Now Vivek Subramanian, electrical engineering professor at the University of California, Berkeley, has made arrays of sensors cheap enough that they could be widely distributed for monitoring toxins in the environment.
The goal is to "identify environmental problems before they become severe, then react to them," says Subramanian. "One of the major requirements, if we want to do this, is ultra-low cost," he says. Subramanian makes his array of inexpensive chemical sensors using organic semiconductors and inkjet printing technology. The first generation of his devices, which would still rely on costly silicon-based technology to process signals from the sensors, would run about 30 cents a piece, Subramanian estimates. That's a bargain compared with several hundred dollars for today's sensors, he says. Subramanian reported on his work at the Materials Research Society meeting in Boston this week. http://technologyreview.com/NanoTech-Devices/wtr_15947,303,p1.html
(Need I mention this is another EARTH predictive hit ;-)
-A cure for computer viruses that spreads in a viral fashion could immunize the Internet, even against pests that travel at lightning speed, a mathematical study reveals. "Honeypot" computers would be linked to one another via a dedicated and secure network and distributed across the Internet. The honeypots would attract a virus, analyze it... http://www.kurzweilai.net/email/newsRedirect.html?newsID=5069&m=15453

In his report, entitled Do potential Seti signals need to be decontaminated?, he suggests the Seti scientists may be too blase about finding a signal. "In science fiction, all the aliens are bad, but in the world of science, they are all good and simply want to get in touch."
