Because basal cell lesions are so common, doctors recommend a thorough skin exam every three years for those between 20 and 40 years old, and yearly for people 40 and older to detect any abnormal growths. And in between, they suggest avoiding the sun during its peak intensity in the middle of the day. If you have to go outside, protect yourself with sunscreen and clothing. If you're worried about a new growth or an existing one that has changed its appearance, see a skin specialist; he can take a tiny sample of the lesion and determine...
Nowhere has Silicon Valley had a more direct impact on biology than in the invention of the miniature laboratory bench known as the DNA microarray. Microarrays detect active genes by exploiting the fact that when the two strands of a gene in the double-stranded DNA molecule are separated, each can readily pick its partner out of a crowd of similar molecules. In a typical microarray, thousands of single-stranded gene fragments are fastened to a platform--usually a silicon or glass wafer but sometimes a nylon sheet. The finished assemblage can be as small as a postage stamp...
...form of noninvasive, "black blood" magnetic-resonance-imaging technique allows doctors to detect problem spots in carotid arteries, the aorta and coronary arteries before patients develop symptoms of atherosclerosis or stroke. The high-resolution MRI blacks out blood flow, offering doctors a clear view of the blood vessels and allowing them to precisely measure the thickness of their walls. Though the black-blood technique still needs improvement, doctors hope the technology will eventually identify those at risk of heart attack long before they have...

...sense to lay off on the strings and backup singers when he recorded Melba and George. Just a strummed guitar, bass, piano (with ace session man Pig Robbins at the ivories), fiddle, dobro and a tasty pedal steel (played by the incomparable Buddy Emmons). I don't even detect a drum beat on this track. In part, this was an attempt to cash in on the early-'60s craze for all types of folk music; no matter, the results are glorious...
