SCIENCE

| Detective Search for Resistant Organisms |
Antibiotics were once called miracle drugs because they revolutionized
treatment of disease, curing bacterial infections that used to lead
to debilitation and, all too often, death. Not only humans, but also
livestock and pets have benefited from these wonder drugs. But over
the years, some bacterial pathogens have developed resistance to the
antibiotics that once spelled their doom. All the while, bacteria
continue to do what they do best—adapt in order to survive.

SOCIETY

| One Farm, One Operator? Not on the Largest Farms |
 The
high average age of primary operators on U.S. farms—56 years
in 2002—has led to concern about the future of farming. However,
some potential "replacement farmers" are currently working
as secondary operators on larger, multiple-generation farms. Today's
commercial farms often require more management and labor resources
than one person can provide. Thus, some farms have more than one operator,
defined as anyone who makes day-to-day decisions about the farm business. |

| Mothers' Beverage Choice Vital to Girls'
Bone Health |
Parents concerned about a young daughter's bone health should
make milk part of their child's mealtime routine. This is according

| The Price is Right: Economics and Obesity |

crisis proportions and grabbed national headlines. While Americans
at the turn of the 20th century may have aspired to be plump, by now
most people are aware of the health problems associated with excess
weight. Diet books top the bestseller list, the electronic and print
media overwhelm us with nutrition do's and don'ts, but progress is
slow or even nonexistent. The reality is that we eat too much and
move too little.
