REE Shows Children in Rural America How Ag Science Rocks

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research portfolio.

You may be surprised by the answers you get when you ask a group of middle schoolers, “What do you like about science?”

Recently, 30 twelve and thirteen year-olds from the Coleman and TL Weston Middle schools in Greenville, Mississippi summed up their answers up with one brief sentence: “I like learning new things about the world around me.” Read more »

When people think about keeping our homeland safe, they don’t usually think about animal diseases that threaten our nation’s economy and food supply, but USDA scientists do. Years of dedicated research on foot-and-mouth disease (FMD) is paying off.

A team of USDA’s Agricultural Research Service (ARS) scientists and their U.S. Department of Homeland Security (DHS) collaborators received the DHS Secretary’s Exceptional Service Gold Medal Award at a recent ceremony in Washington, D.C. The award recognizes outstanding leadership or service distinguished by achievements of national or international significance that improves our homeland security. The team successfully developed and licensed the world’s first molecular FMD vaccine for cattle—the most significant scientific accomplishment in FMD vaccine development in the past 50 years and the first FMD vaccine that can be manufactured in the United States.

Fast-Food Purchasers: Examining Their Time-Use Patterns

Time-use patterns may provide clues to what motivates purchases of fast food, in a new study from USDA’s Economic Research Service.

Time is a limited resource. Deciding on how to utilize each minute in your 24-hour day is crucial.  However, the choice between using a portion of the day for food shopping, cooking, and cleaning up versus grabbing a fast food meal can have implications for our health and diet quality as well as other aspects of well-being. While fast-food purchases may save time, they have been linked to Americans’ poor diet quality and expanding waistlines.

Time-use patterns may provide clues as to what motivates fast-food purchases and in this way may help inform policies and other initiatives aimed at improving Americans’ diet quality.  Recently, we used time-use diaries from a nationally representative survey to examine how the time-use decisions of those who purchase fast food on a given day differ from the average of the U.S. population.

Most are familiar with the phase, “Sleep tight, don’t let the bed bugs bite,” but few people know what a bed bug looks like or problems they can cause. From World War II until just recently, bed bugs were not at all common in the United States.  Bed bugs are now found in many homes, apartments, college dorm rooms, and even in public facilities such as theaters, hospitals, schools, and libraries.  Now that bed bugs are back, everyone needs to know how to recognize them, how they move from one location to the next, and where they hide so we can prevent large infestations.

Why Test Seeds?

Before the late 1800’s, there weren’t any standards or laws overseeing the seed trade.  This allowed individuals to take advantage of the unorganized seed market by selling low quality seed to buyers.  In some instances, what was sold wasn’t even seed at all.

Unfortunately, even the most seasoned seed buyers can’t always tell what they will get when purchasing seed.  Will the seed grow?  If it does grow, what will it grow into?  Will these seeds contain a disease that will hurt my other crops?  Will the packet contain other unwanted weeds that will reduce my yield, hurt my animals, or destroy my land?  The worst part is that the outcome of your purchase won’t be known for months after you buy and “try” to grow them.  In the late 1800’s, these questions asked by millions of people around the world led to the rapid development of laboratories tasked with using science to predict seed quality.  Read more »
