...Alzheimer's work harder to answer easy mental tests than other people. How can doctors tell? On the MRI, the area of the brain responsible for thinking lights up more than other areas. The tool may one day be used as a kind of mental stress test to detect Alzheimer's earlier, much as a treadmill tests for heart disease today...
...column of warm air that rises from the feet to the top of one's head, catching constantly shedding skin cells. Settles even has a catchy name for this phenomenon: the human thermal plume. He has created a portal, similar to a walk-through metal detector, that can detect the presence of microscopic amounts of explosive material in the plume...
Travelers passing through the detector will feel a rush of air as a fan blows the plume--and the dead skin cells with it--into a particle separator, which is able to detect the presence of bombmaking materials and other contraband sticking to the skin. Though the invention is thus far being designed only to detect bombs, Settles says his portals could also be used to detect illegal narcotics, smuggled money and evidence of chemical or biological weapons...
...will be about 1,500 miles from its target. Over the next six to eight minutes, the interceptor will try to hunt down its prey and guide itself into a suicidal collision with the warhead. It will be receiving guidance from far below as early-warning radar systems detect the incoming warhead. These systems hand off data to a so-called X-band radar system based on Kwajalein, which stabs the sky with a narrow beam of electronic pulses. The X-band's shorter wavelengths and advanced signal-processing capabilities give it the power to "draw" a clear image...
Mammograms have saved the lives of tens of thousands of women over the past 20 years. Though mammograms are not perfect, their ability to detect small tumors gives doctors and their patients the option of treating the cancer while it is in an early, more curable stage. And yet by the time even a small tumor is picked up on a mammogram, odds are it has been growing for five to seven years. What if doctors could find even younger (and therefore presumably easier to treat) breast tumors? That's the question that a group of researchers asked themselves...
