from around the globe on new uses for agricultural products.

Soy blocks the sun
A soy-based sunscreen has become the platform for an entire
class of cosmetics. The SoyScreen formula, designed by ARS
scientists in the late 1990s, is now being sold by iSoy
Technologies Corporation of Cary, Ill. as a key ingredient
in wrinkle-prevention products marketed by a major cosmetics
company.

Blueberry brain boost
Blueberries have boosted brain activity in laboratory rats
suffering from neuritic plaque buildup, often seen in
Alzheimer’s disease. Researchers at Tufts University in
Boston fed adult rats, with the telltale brain buildup, a
diet containing blueberry extracts. The control rats with a
similar condition were fed standard fare.
After eight
months, memory-maze tests showed rats with blueberry-extract
diets fared as well as those with no buildup, and scored
much higher than rats not fed the berry extracts.

Too hot for pests
A fiery habanero
pepper, developed by USDA researchers, not only blasts taste
buds but pests too. The Tiger Paw-NR pepper, developed at
the U.S. Vegetable Laboratory in South Carolina, is
resistant to nematodes that can seriously damage pepper
plants. The natural resistance offers an alternative to
applying chemicals to combat the nematodes. Based on the
standard heat scale, the new habanero pepper is more than
three times hotter than a typical habanero and more than 100
times hotter than an
average jalapeno.

Catnip
cologne
ARS
researchers in Maryland have identified a catnip-oil
compound that attracts natural predators to destructive
aphids and mites. Iridodial imitates the pheromones of the
male lacewing. This natural cologne attracts both male and
female lacewings, which then feed on the damaging mites and
aphids, providing natural biological pest control.

Film at 11
Dairy and biofuel
byproducts may soon keep food fresher. Scientists at the
USDA Eastern Regional Research Center in Pennsylvania have
discovered a process that combines water with milk casein
and glycerol to produce an edible film for protecting food.
Glycerol is left over from biodiesel production.
Like conventional
packaging, edible films can extend the shelf life of many
foods, protect products from damage, prevent exposure to
moisture and oxygen, and improve appearance. From: USDA-ARS,

Soy for bones
Brazilian scientists have determined that soy-based yogurt
and exercise help increase bone density. Researchers found
that soy isoflavones in yogurt were capable of preventing
bone loss or even increasing bone mass in laboratory rats.
Through a series of tests on various control groups, rats
receiving both the yogurt and exercise fared best.

Easing menopause
Naturally-occurring edible plant compounds called
polyphenols have been shown to help battle unwanted side
effects of menopause. Scientists at the University of
Alabama, Birmingham have conducted studies that show
polyphenols found in grapes, soy and kudzu can help blunt
cognitive loss, hypertension and insulin resistance. The
natural treatments also showed fewer side effects than
standard hormone replacement therapy.

Bright eyes
Nutritional
supplements of omega-3 fatty acids may prevent eye disease
according to researchers at the Harvard Medical School and
National Eye Institute.
A study found
that increased consumption of omega-3 improves the balance
with omega-6 fatty acids, which have been linked to an
increase in risk of retinopathy, a sight-threatening disease
affecting four million premature infants and diabetics in
the United States. Increased omega- 3 consumption reduced
abnormal blood vessel growth in the eyes, which is a
hallmark of retinopathy.
Omega-3 fatty
acids are in fish, flax and eggs from chickens fed diets
containing flax.

Nutty fuel
While America’s biodiesel
industry is now fueled primarily by soybean oil, scientists
are working on other nutty options. ARS researchers at the
National Peanut Research Laboratory in Georgia are testing
peanut varieties not suited for commercial edible standards,
but are high in oil and with low production-input costs.
Scientists say soybeans produce about 50 gallons of fuel per
acre, while peanuts can produce 120 to 130 gallons of
biodiesel per acre.
