Future Scientists Program teachers in the field with ARS research entomologist John Goolsby, learning about his research on bio-control for Giant Reed (Arundo donax) in the Rio Grande Valley.
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.
The goal of USDA’s Hispanic-Serving Institutions National Program (HSINP) Future Scientists Program is to enhance the scientific knowledge of teachers, helping them to become more effective in encouraging student interest and progress in science. Teachers in the program attend two-day summer institutes at Agricultural Research Service (ARS) labs nationwide, where scientists introduce them to various research projects. ARS researchers share scientific knowledge with the teachers, who then share it with their students to encourage them to become future scientists.
One of the catalysts for this lofty goal is a tiny, inconspicuous and innocuous caterpillar—the corn earworm that wreaks havoc in corn fields nationwide as an agricultural pest. This program began in 2003. I brought 10 teachers into the ARS Southern Plains Agricultural Research Center (SPARC) in College Station, Texas, for a summer institute that included teachers studying in corn research plots searching for corn earworm caterpillars in 100-degree heat! It was the first time I made caterpillars the focus of this program. Read more »

You probably know that climate change affects how we grow food, but you might not know that how food is grown also affects our climate. This interplay is at the heart of an Agricultural Research Service (ARS) project called “Soil and Air,” a concerted effort to feed the Earth’s 7.5 billion people while protecting the planet.
Farmers and ranchers produce food at the intersection of soil and air, which in turn impacts soil and air quality. For instance, warmer air creates warmer soil, leading to different compositions of bacteria and other microbes in the ecosystem and to increased moisture loss through evaporation. Read more »

About once every five years since 1991, the National Beef Quality Audit (NBQA) brings together producers, consumers, academia, and government in a collaborative research and data collection exercise that spans the entire U.S. beef industry. Funded by the Cattlemen’s Beef Board (the beef checkoff program), the NBQA assesses the current status of the industry regarding production processes and practices that ultimately affect consumer demand for beef.
The audit uses a multi-phase approach to identify the top challenges the fed-beef (cattle raised for meat production) industry faces. The NBQA first gathers data to measure current quality and consistency of U.S fed-beef, and then quantifies the level to which cattle producers are applying common sense husbandry techniques, specifically the Beef Quality Assurance principles, to safeguard that quality. The results are translated into practical guidance for continued improvement in the production of fed-beef and, in turn, consumers’ acceptance of the end products found in stores. Read more »
Summer meals help close the nutrition gap children face when schools let out for summer — when children no longer receive school meals they relied on throughout the school year.
The following guest blog discusses the importance of USDA Summer Meals Programs, which provide children with healthy food during the summer, when the school meals they depend on disappear. Childhood memories shared by the writer demonstrate how critical healthy meals are to the growth and development of children. USDA’s approaches to making summer meals accessible are also highlighted.

When I was young, summers seemed to last forever. Days were long and hot in rural South Texas.
One thing I looked forward to after riding my bicycle all over the neighborhood was a nice lunch prepared by my grandmother Angelita. Meals like arroz con pollo (rice with chicken) or carne guisada (stewed meat) with a side of beans provided the energy I needed to keep up with an adventurous summer.
Good food not only helps your body climb hills when you’re a kid, but it helps your brain develop in order to learn new stuff. For some children in our communities, though, not enough healthy food is available for them to enjoy and help them grow. Luckily, a very helpful program exists that communities can use to tackle this problem: USDA’s Summer Meal Programs. Read more »

All this month we will be taking a look at what a changing climate means to Agriculture. For APHIS, changes in environmental conditions will increase the likelihood of shifts in the distribution and nature of current domestic diseases, invasive species and agricultural pests. These changes will likely influence the dynamics of invasion and establishment of these diseases and pests, and therefore much of APHIS’ work. Understanding and adapting to these changes is therefore critical to meeting our mission.
Vampire bats rank high on the list of animals that scare us the most. Spooky Halloween tales of their blood-sucking, nocturnal, and secretive habits have likely led to their bad reputation. The fact that some also carry and spread the deadly rabies virus doesn’t help.
The common vampire bat feeds on the blood of Central and South American wildlife and livestock. They also sometimes bite and feed on the blood of people. Recently, vampire bats have been documented within 35 miles of the Texas border. This has caused concern and speculation about the potential movement of vampire bats to areas within the United States as a result of rising global temperatures. To gain a better understanding of the likelihood of such movement, USDA-APHIS geneticist Dr. Toni Piaggio with the Wildlife Services National Wildlife Research Center partnered with U.S. Geological Survey scientist Dr. Mark Hayes to analyze and map the potential distribution of vampire bats under various climate scenarios.

Spring brings new life to the fields and forests and wild turkeys are one of the most interesting spectacles this time of year. Male turkeys gobble and strut to attract the attention of hen turkeys. Hens, in turn, go off and lay their eggs- one egg each day until the clutch is complete and the hens then begin incubation.
Unfortunately, this spring more than ever, wild turkeys across the U.S. are facing an increasing threat from a new and rapidly expanding population of nest predators…feral swine. Feral swine, also known as wild pigs, feral hogs, and wild boars, are not native to North America and are the descendants of domestic swine which either escaped or were liberated. In some cases, feral swine are intentionally released to create new hunting opportunities. But these opportunities come at the expense of other wildlife, including ground nesting birds such as the wild turkey. Feral swine are highly adaptable and can learn to seek out turkey nests even before the hen starts incubation, consuming the eggs when left unprotected. When a partially completed clutch is depredated, the hen is forced to start over, depleting vital reserves within herself as well as risking lower nest success and chick survival. Read more »
