How do you get tent caterpillars and termites to follow a circle on a piece of paper? Paint the circle with pheromones.

This was one of the many cool facts that kids and adults learned perusing the USDA exhibits at the USA Science & Engineering Festival this past weekend.   I joined thousands of people during this three-day event designed to revive interest in science, technology, engineering, and mathematics (STEM) and promote careers in those fields.

April, the springboard to warm, sunny weather, is National Minority Health Month—a good time to focus on the sun, vitamin D insufficiency for African-Americans, and the ways that monitoring its intake have improved.

Vitamin D is primarily produced by exposure to the sun’s ultraviolet rays. However, African-Americans have more melanin in their skin, resulting in the reduction of the body’s ability to make the vitamin from sun exposure.

Of the many factors that make farming risky, weather is particularly important. With this year’s unseasonably warm March, some farmers are taking a risk they hope pays off in a big way. Despite the peril of a spring frost, many farmers are planting corn almost a month earlier than the usual mid-April planting dates.

As they wait to see what happens with the weather, these farmers, along with analysts, policymakers and others interested in U.S. agriculture, will pay close attention to the Crop Progress report issued weekly by USDA’s National Agricultural Statistics Service (NASS).

To help those in need make ends meet, the Federal Government offers a variety of assistance programs.  Some provide cash, but more offer in-kind assistance such as subsidized rents or assistance with home energy bills. USDA provides eligible households with in-kind assistance in the form of Supplemental Nutrition Assistance Program, or SNAP, benefits to buy groceries (formerly called the Food Stamp Program). But these benefits, and other in-kind assistance, are not counted as income when the Census Bureau calculates official poverty rates.  Not accounting for these benefits understates the resources of U.S. families who receive them and masks the greater relative hardship of those who do not.

Porcine reproductive and respiratory syndrome (PRRS) is a disease that costs the U.S. pork industry an estimated $664 million per year. Recently, scientists have made a breakthrough in research efforts to curb the disease.

A consortium of scientists from around the country, with funding from USDA’s National Institute of Food and Agriculture (NIFA) and Agricultural Research Service (ARS), have discovered a genetic marker in pigs that identifies whether or not a pig has reduced susceptibility to PRRS.

Each day, the work of USDA scientists and researchers touches the lives of every American: from the farm field to the kitchen table – from the air we breathe to the energy that powers our country.

No matter where you look, USDA science is on the cutting edge, helping improve American agriculture, providing insight into our health and nutrition, and protecting our natural resources.

For over 100 years, USDA scientists and research funding have supported the farmers and ranchers who produce a safe and abundant food supply for our families. This work has helped sustain an agricultural trade surplus since the 1960s and led to the record farm income we’re enjoying today.

Join us tomorrow for a Twitter chat to discuss womens' increasing role in science, technology, engineering and math (STEM). We'll be sitting down with Jenna Jadin, Ph.D, Office of the Chief Scientist and Dionne Fortson Toombs, Ph.D., National Institute of Food and Agriculture (NIFA) to answer your questions from our USDA Twitter handle, @USDA. We look forward to seeing you, and check out the Department of Energy's blog for additional info!

This week marks the 19^th year of World Water Day. The United Nations Conference on Environment and Development designated this day as an annual international event focusing on the importance of sustaining and managing fresh water resources.  This year’s theme is water and food security.  This is such a critical issue to not only to our international friends, but also for U.S. farmers, ranchers, growers, consumers, and conservationists.

As more and more Americans are working to become fit and healthy, one of the top athletic clothing companies – Under Armour – has been building a team to help improve its use of natural fibers.  Relying on cutting edge research to provide products that wick away moisture, Under Armour products traditionally were not made of the classic sporting apparel material - cotton.  However, since early 2011, one of the company’s most popular items has been Charged Cotton™, a line of clothing that uses cotton -- the fabric of our lives.
