A calculator and a clipboard aren't enough for this college-level summer course. Backpacks slung over the shoulders also contain the necessities -- insect repellant, a canteen of water and perhaps a roll of biodegradable toilet paper. This summer, classroom learning has been converted to outdoor experiences for about 50 forestry majors.
Looking for ways to increase producer profits while conserving environmental resources drives modern agricultural science, say a trio of USDA Agricultural Research Service (ARS) researchers at the Conservation and Production Laboratory at Bushland.
When a farmer looks at a clump of good Panhandle soil, what's in the dirt isn't readily evident to the eye. The action starts at the molecular level where particulate matter and life forms include the pathogens which cause disease. And, for area sugar beet growers, diseases in that mix can have devastating consequences to yield, and profits.
Starting this year, two agricultural engineers at the USDA-Agricultural Research Service Conservation and Production Agricultural Research Laboratory are gathering data to compare the efficiency of low-energy precision (LEPA) and low-elevation spray (LESA) application devices with the more common overhead spray heads.

Tanks may be destructive by nature, but with the help of the Texas Agricultural Experiment Station, the U.S. Department of Defense is trying to make them more environmentally benign. A water-quality monitoring project at Fort Hood, Texas is helping determine how soil erosion may be impacted by military training exercises. The information will be used to reduce environmental impacts.
Researchers already know ryegrass can save water and provide good forage for South Texas ranchers, but using it to best advantage with cattle can be a tricky business. Researchers have found that cattle with some fiber in their diet before they are turned onto the grass have good weight gains and fewer digestive problems, but the facts on exactly how and when to balance cattle diets are still somewhat elusive.
Researchers at the University of Wisconsin-Madison have found that limiting calorie intake later in life can stall some of the muscle deterioration that normally accompanies aging. Reported in the June FASEB Journal, the research involved age-related fiber loss and enzyme and gene abnormalities in rat muscle.

The National Science Foundation (NSF) awards Small Business Innovation Research (SBIR) grants to stimulate technological innovation that meets federal research and development needs. NSFÃs SBIR budget for 1997 is $50 million. The program makes it financially possible for small firms to undertake high risk, cutting-edge research with strong potential for commercial results. The following are a few of the many SBIR success stories.
Technology being developed at the Department of Energy's Oak Ridge National Laboratory to save lives on the battlefield and in hospitals closer to home could one day be used in baby cribs to help prevent Sudden Infant Death Syndrome.
Embargoed for 5 p.m. EDT, June 14 -- In the Annals of Internal Medicine multicenter AIDS cohort study researchers report that a concise decision tree using two tests in combination -- viral load measurements and CD4 T cell counts -- determine progression to AIDS and death from AIDS in HIV-infected individuals.
A combination of measuring plasma viral load (the amount of genetic material in circulating virus) and CD4+ lymphocytes in people who are HIV-infected gives the most accurate prediction of the time when those people will develop AIDS. This information forms a critical part of the decision about when to begin antiretroviral therapy.
Researchers at Northwestern University have constructed a tiny nanoscale phototonic resonator that is a hundred times smaller than the cross-section of a human hair--so small that it can only be seen with an electron microscope. When combined with an equally tiny semiconductor laser, these components can form nanoscale photonic integrated circuits that are a thousant times smaller than those currently in use, and which should be cheaper to fabricated and more efficient to use.

As every parent knows, children can display their feelings in many ways. They can hang their heads, whine and cry or kick and scream. On the other hand, they may bottle up their feelings and do nothing. Janice Zeman, University of Maine assistant professor of psychology, is taking a close look at the emotional lives of children from pre-school age through the teen years. She and her doctoral students have been asking questions and observing children directly in situations designed to elicit sadness, frustration or anger.
A preliminary study conducted at Albany Medical Center of a new imaging agent has shown promising results that may lead to significant improvements in the early detection of pulmonary embolism (blood clots in the lungs) of hospitalized patients.
Patients who have heart attacks, or myocardial infarction, were no more likely to delay seeking emergency treatment when an insurance copayment was required than if a copayment was not required, according to the results of a five-year study released today. The study, conducted by a University of Colorado Health Sciences Center assistant professor, appears in the June 12 issue of The New England Journal of Medicine.
If you borrow as much as a lender will give you to purchase a home, you may be spending more than you can afford, says a Purdue University expert on family budgeting. "The mortgage payment is only 60 percent of total housing costs," says Flora Williams, associate professor of family and consumer economics. "People underestimate the cost of owning a home, and rules on affordability need to be changed in light of a growing number of personal bankruptcies."
Nature's tiniest ice cubes are providing new information about the unique properties of water. A Purdue University study shows that when water molecules are cooled to very low temperatures, naturally arrange themselves into small cubic structures that come in two forms.
Harvard Medical School researchers have identified a method to control growth hormone (GH), which can cause retinal neovascularization, an abnormal growth of new blood vessels that can destroy sight. This discovery, reported in the June Science, could lead to new ways of preventing and treating certain eye diseases.

Clouds of primordial gas located near the outer reaches of the Universe appear to be infant galaxies whose behaviors are surprisingly similar to their grown-up counterparts, including our own Milky Way. According to new studies by astrophysicists at University of California, San Diego, the fact that these protogalaxies form relatively thick disks that rotate as rapidly as the mature gallaxies we see today contradicts accepted theory.
Businesses are getting caught in the squeeze between wage and price inflation, says the director of the Center for Economic Studies at Babcock Graduate School of Management, Wake Forest University. Gary Shoesmith, director of the center, says " If interest rates increase this summer, businesses will feel the full brunt. But consumers, receiving higher and higher wage gains, are not nearly as affected."
