AND IT'S GREAT WITH PROSCIUTTO
Trichloroethane is widely used as a cleanser in microchip
manufacturing. Unfortunately, it also attacks the planet's
ozone layer, so chipmakers are looking for a substitute. Now
AT&T may have one in N-butyl butyrate, a chemical found in, of
all things, cantaloupes, peaches and plums. In fruit, it
contributes to overall flavor; in the atmosphere, it should help
reduce mankind's siege of the ozone layer, in turn relieving
the onslaught of cancer- and cataract-causing ultraviolet light.
SEX AND THE SINGLE WORM
Every biologist knows that females spend a lot of energy
making a small number of eggs, while males churn out huge
quantities of sperm almost effortlessly. Not so, says a scientist
who has studied the sex life of a worm no bigger than an
apostrophe. Male soil nematodes that copulate a lot -- and thus
produce a lot of sperm -- live only two-thirds as long as fellow
worms that copulate but don't make sperm, according to a report
in Nature. University of Arizona researcher Wayne Van Voorhies
warns that it may be a mistake to make the leap from worms to
humans, but women live, on average, six years longer than men.
