...microarray--is one of the most powerful tools in modern biology. Genetic material from the cell being studied is poured over the microarray and incubated in a solution containing fluorescent snippets of the same genes. If a gene is active, a corresponding gene on the microarray glows under UV light--a visual snapshot of the cell's genetic script. "Microarrays," says Brown, "offer an easy way to see the language the genome uses to send instructions that define every cell in your body...
...trouble shows up right away. Water skiers, or snow skiers for that matter, can develop a type of temporary blindness, called photokeratitis, that occurs when reflected sunlight actually burns the cornea, the clear covering over the eye. Other conditions may be triggered after years of exposure. Studies have linked UV radiation to an increased risk of cataracts, in which the lenses of the eyes become cloudy, as well as to macular degeneration, in which the cells in the central part of the retina slowly...
...Whether you're eyeing a $175 pair of Persols or a $20 bargain from the drugstore, make sure there's an official decal indicating that the lenses absorb 99% to 100% of the UVA and UVB rays. What you shouldn't accept, however, is any nonspecific wording such as "UV block" or "maximal UV protection." Specific numbers should always be attached...
...strange box appears outside your bedroom window? You can try calling the company to ask if it will move the thing. (That's what Metricom, in the interest of fostering good community relations, finally did for me.) Alternatively, there are a number of products designed to keep out UV light that can also block radio waves. Radio frequencies travel easily through glass, but not through bricks or metal. 3M sells Neutral Series Scotchtint, a professionally applied coating that covers windows with a nearly transparent layer of metal. MSC Specialty Films offers a similar product. If you're desperate...
Lines, colors, positions of shapes-—additions and subtractions run rampant throughout Mondrian’s paintings. Displayed in the exhibit are the fruits of exhaustive research, as UV photos show changes to the works. His works were in a constant state of flux...
