CARELESSNESS ITU PANGKAL DOSA ! Tidak mau tahu iptek juga satu sisi tak peduli. Di TV fakta seorang petinggi terhormat (dhi yang mulia Kalla) bilang gempa tak dpt diprediksi adalah kekeliruan fatal, sementara aneka media/TV negeri tetangga tengah gencar menyebarluaskan sebaliknya. Pejabat omong lancung adalah tanda negeri sakit. Akan tetap diamkah warga negeri tanpa berbuat koreksi ? KEDEGILAN BUKAN DOSA ?

Tue Mar 29,12:14 PM ET LOS ALAMOS, N.M. - Los Alamos National Laboratory scientists are using a new technique to see fingerprints on surfaces that typically make them invisible. The method uses a technology called mini-X-ray fluorescence to detect chemical elements in fingerprints without altering them, said Christopher Worley, a scientist on the project. "The conventional methods are meant to bring out fingerprint patterns with regular light � and they have to treat those with powder, which alters them," Worley said. "With this you don't have to alter it or treat it at all. We can determine the elements in a fingerprint and get a pattern at the same time." The technology focuses a tight beam of X-rays on surfaces with fingerprints and creates a computer picture out of those scans. The equipment costs about $175,000. For big labs, the method could be a great way to bring out prints that can't be seen any other way, said Vahid Majidi, another lab scientist. "The technique fills a unique niche," Majidi said. "These are prints that would otherwise be useless. If you have prints on a dark surface, for example, they really don't develop well using normal techniques. If you have prints from an adolescent or child, the chemicals in the fingertips are different and don't stick around long enough for traditional methods." The new method might also be able to tell if the person that left them handled certain types of bomb-making materials, said George Havrilla, another lab scientist. "This is a new approach to fingerprint visualization," Havrilla said. "We're lifting prints, but instead of looking at the finger's natural oils and organic residues we're looking at elemental features left behind." The technology for scanning the prints is widely available. What's new is the method the lab has created to see them � which includes computer software and ways of manipulating the machinery, Worley said. But the technique isn't for everyone. "We've already had some negative comments on it," Havrilla said with a laugh. "One reviewer told us it's just not practical. But the goal of our work was to demonstrate that it was feasible to see these things." The lab is interested in working with New Mexico police agencies to do more tests on the method, Worley added. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
