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.

The old proverb: “You can’t see the forest for the trees” should have continued with a line saying that it’s even harder to see below the trees. Because seeing under trees, their root system to be exact, is how scientists understand and appreciate the things that will determine what we all see in our future forests. A new publication just released by the US Forest Service seeks to help forest managers recognize important root diseases and provide the best management strategies.

Ordinarily, we depend on decay organisms to break down wood to recycle enormous amounts of above ground materials such as leaves, limbs, and tree trunks. Without these subterranean decomposers, we would find ourselves buried in forest debris. But what makes beneficial decay organisms go bad and attack the root systems of living trees?  In a word, disease.

Environmental trading markets are springing up across the nation with goals of facilitating the buying and selling of ecosystem services and helping more private landowners get conservation on the ground.

USDA Secretary Tom Vilsack and EPA Administrator Gina McCarthy joined Virginia Governor Terry McAuliffe in December 2014 to announce the state’s first trade under its nutrient trading program for stormwater.

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.

Just like a smart phone helps users learn, communicate and make important decisions, smart technology—known as precision agriculture—helps farmers know and apply critical information about the right investments in fertilizer, seed, pesticide and water needed to produce their crops. Through new technologies, farmers produce more efficiently and see an increase in profits while improving stewardship of ecosystems and local communities.

To talk about precision agriculture is to talk about mapping the amount of a crop grown per acre (yield) or the types of soils in a given area. It also includes the technology that automatically guides farm machines and controls variables like the rates of seeds, fertilizers or chemicals.

When Hurricane Matthew hit last month, disaster struck as high flood waters devastated communities up and down the East Coast. Agricultural producers in Eastern North Carolina were hit especially hard and suffered devastating losses to crops, livestock, and property.

Secretary Vilsack recently designated 39 counties in North Carolina as primary natural disaster areas, in addition to 15 contiguous counties. This week, I traveled to the state to visit some of the communities that were affected. I saw a peanut farm littered with uprooted plants and cracked shells. I met with an organic tobacco producer whose top soil had completely washed away. I visited a sweet potato and soybean farm that suffered hundreds of thousands of dollars in losses. We drove by washed out roads and gutted homes with waterlogged furniture piled high on the side of the road.

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.

The 567 federally-recognized Native American Tribes are unique in their own way—from their languages and family structure, to their clothing and food. Tribes are working hard to revive their roots to help reconnect their heritage to the land, rekindle their spiritual bonds and cultural traditions, and raise awareness amongst future generations; especially tribal youth in line to inherit the land.

USDA’s Natural Resources Conservation Service (NRCS) works with the tribes like the Choctaw Indians, comprised of nearly 10,000 members across the United States, to farm and harvest hickory king corn and other heirloom white varieties, and process them to make hominy. Hominy is made from dried corn kernels, but it is expensive to purchase. NRCS provides the tribe with technical assistance to help transform idle land into a hominy-making enterprise–enabling the tribe to provide their own locally-grown, fresh produce, and cut their expenses by growing the corn.

For the second year, the U.S. Forest Service is part of the administration’s Every Kid in a Park program, an initiative to provide American fourth graders with a free pass to more than 2,000 federal land and water sites for them, their siblings and up to three adults.

The pass includes access to 153 national forests, 20 grasslands and one tall grass prairie managed for the public by the Forest Service and other lands and waters managed by six other federal agencies. Some state parks also honor the pass.

Habitat conservation practices make a difference for lesser prairie-chickens. That's the finding of a recent scientific study – the first part of a multi-year study – described in a new report from the Lesser Prairie-Chicken Initiative (LPCI).

LPCI, led by USDA’s Natural Resources Conservation Service (NRCS), works with partner organizations and ranchers to improve habitat and address threats to the bird. Since 2010, more than 1 million acres of habitat have been restored on working lands.

I was thrilled to celebrate with key partners and contributors in Napa County, California, recently at an event to recognize the critical safeguarding accomplishment we achieved together, that of eradicating the invasive European grapevine moth (EGVM) from the United States.

Leaders from the USDA, Animal and Plant Health Inspection Service (APHIS), the California Department of Food and Agriculture (CDFA), and the California County Agricultural Commissioners came together with growers and industry representatives, who found and implemented the right tools to safeguard California grapes. In front of these critical partners, I was proud to recognize the extraordinary individual and group contributions that made the eradication of EGVM possible.
