...more futuristic image search, which can scan and recognize facial images, is being developed by Massachusetts-based Viisage. It focuses on unique marks on the human face--cheekbones, tip of the nose--and can cross-reference pictures with databases, much to the interest of law-enforcement and intelligence agencies. In Florida, the Pinellas County sheriff's office has outfitted troopers' cars with a system that uses Viisage technology. If a trooper sees someone acting suspiciously, the officer can take a digital image of the person, upload it to a database of criminals, and get back any hits. How hard...
...favor Fackelmann did may well have saved his life. The scan revealed a major blockage in one of his coronary arteries. A few days later, doctors propped open the dangerously clogged blood vessel with a stent, thereby preventing what could have been a heart attack. "I would have been one of those guys who was just out jogging with my son or playing basketball and died," Fackelmann says. "There was never any reason for me to suspect that there was such a dramatic lesion in my heart...
What that means is that millions of patients will probably get the treatment that better matches their condition. Some doctors are already starting to use the scans to figure out which of their otherwise healthy-seeming patients need to be taking cholesterol-lowering drugs like statins, and may even be able to decide what to do in marginal cases without having to resort to an invasive angiogram. Patients with a clean scan, on the other hand, can feel confident that they don't need statins or other medication, along with their potential side effects...
...trouble is that there's no single type of scan that easily and inexpensively shows you everything you need to know about the heart. In addition, some tests are better at evaluating anatomy--the physical structure of the heart--while others tell you more about how well various parts are working. Doctors need to know both kinds of information before deciding the best course of treatment. Frequently, a new set of answers raises new questions, however, which require more extensive testing. The ultimate goal, cardiologists say, is to find the single test that provides "one-stop shopping" and eliminates...
...vigilant and largely unsung astronomers who scan the skies for asteroids that could threaten the Earth, there is some good news and some bad news about 2004MN4. This was the initial designation for an asteroid that caused a flurry of alarm among scientists when it was discovered last December apparently heading for a frightening rendezvous with our planet on April...
