A Root Beer-Based Discovery that Saved Lives

Science can do more than improve people’s lives; sometimes it can save them.

Consider the contributions of the late Allene Rosalind Jeanes, an Agricultural Research Service (ARS) chemist at what is now the National Center for Agricultural Utilization Research in Peoria, Illinois. Her efforts are particularly worth celebrating this Veteran’s Day.

Jeanes studied polymers (large molecules composed of many repeated subunits) found in corn, wheat and wood. She spent long hours investigating how bacteria could produce polymers in huge fermentation vats. Eventually, she found a way to mass produce dextran, a type of polymer, so that it could be used as a blood volume “expander” to sustain accident and trauma victims who have lost massive amounts of blood and need to get to a hospital for a transfusion.

People behind Scientific Innovation at USDA

Dr. Woteki works with 4-H members.

The past eight years have been an extraordinary time for agricultural science, and for the application of new insights from other fields to enhance agricultural productivity and the overall agricultural economy. As the final days of this administration are approaching, it gives me a great deal of pride to look back at what USDA has accomplished in the areas of research and innovation.

Scientific research is a fundamental part of our mission at USDA. But, ultimately, what’s behind all the science is people – people who do the research and people who are affected by it. As USDA’s Chief Scientist and Under Secretary for Research, Education and Economics, I’ve met and worked with both as I’ve traveled across the country and around the world. Read more »

Using Science to Help Keep Food Safe: A Day in the Life of a USDA Laboratory Auditor

Isaac Gene Sterling

A fascinating part of Gene Sterling’s job is learning the different uses for the products that are being tested by USDA audited laboratories across the country. Did you know that peanuts are used in sauces, gravy and soup mixes as well as snack foods?

July is the height of summer grilling season, and throughout the month USDA is highlighting changes made to the U.S. food safety system over the course of this Administration. For an interactive look at USDA’s work to ensure your food is safe, visit the USDA Results project on Medium.com and read Chapter Seven: Safer Food and Greater Consumer Confidence.

From soup to nuts, we use science to help ensure the quality of agricultural products for consumers worldwide. As a Microbiologist for USDA’s Agricultural Marketing Service (AMS), I am one of a small group of highly-qualified auditors that travel across the country to certify over 70 private laboratories. These labs are consistently testing to verify the quality and wholesomeness of U.S. food and agricultural products.

Our Laboratory Approval Service approves, or accredits, labs that test agricultural products in support of domestic and international trade. Our programs cover a variety of products from aflatoxin testing in peanuts and tree nuts to export verification for meat and poultry products. Read more »

Using Market Data to Feed the World

Consumer and Industry Outreach, Policy, Markets and Trade graphic

Science and data may hold the key to how the world will feed 9 billion people by 2050, and USDA Research and Science Action Plan will help guide the way.

In 2050, there will be about 9 billion people in the world. How do you feed 9 billion people? Clearly, we need more food, greater production, and more efficient processes, but how do we achieve that and how does that translate to success?

The answer may be found through science and data.  USDA works hard to provide good data to decision makers on the farm, in the field, at the lab and in the office place. This data includes economic information that characterizes and evaluates global market performance and keeps food and agricultural systems working smoothly.  Information includes data on crop production, farm income, food and agricultural prices, trade, nutrition, and food security.

Students Intrigued Enough to ‘Worm’ Their Way into Ag Science

Future Scientists Program teachers in the field with ARS research entomologist John Goolsby

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.

How College Catapults Students to Ag Careers

Gracie Valdez explains how traveling around the world helped her to want to pursue a career in international agricultural development and trade.

Growing up, the question of the day often started with “why” or “how” because I loved discovering things. Though my specific interests morphed from archaeology to geology to biology, I knew I wanted to be a scientist since the 5th grade.  In college, I chose to study biology, which exposed me to many different aspects of the field.  College was the springboard that sharpened my focus and led me to becoming the ecosystem ecologist I am today.  Recognizing National College Signing Day, I hope that today’s inbound students consider studying science, technology, engineering and math (STEM) subjects to help meet our future agricultural challenges.
