‘Bee’ing at White House Day at the Lab

Students from Baltimore and Washington, D.C. schools trying out different scientific careers like ARS bee researcher at the White House Day at the Lab

Students from Baltimore and Washington, D.C. schools try out different scientific careers like ARS bee researcher at the White House Day at the Lab.

“Whoa! Do you have bees in there?” is not something the Secret Service asks every day, even of scientists when they come to the Eisenhower Executive Office Building, which sits next to the White House West Wing and houses most of the staff offices.

It was just a month ago that agronomist Eton Codling, from the Agricultural Research Service (ARS) Crop Systems and Global Change Lab, and I, research leader of the ARS Bee Research Lab, were on our way into the White House. We were there to represent USDA at the White House Day at the Lab to give young students a taste of exciting science careers they may never have considered or even known about otherwise. Read more »

Real Superheroes Wear Lab Coats

With support from the U.S. Department of Agriculture’s National Institute of Food and Agriculture (NIFA), the National Plant Diagnostic Network has grown into an internationally respected consortium of plant diagnostic laboratories dedicated to enhancing agricultural security by protecting health and productivity of plants in agricultural and natural ecosystems.

Dr. Ray Hammerschmidt, President of the National Plant Diagnostic Network, discusses this partnership and the benefits all Americans receive in the following guest post:

Superheroes really do work among us. But, instead of capes and cowls and ice palaces and caves, they are often found in a lab at a public university or state agriculture department, wearing lab coats and working over a microscope.

These men and women work daily to protect our communities and crops from dangerous pests and pathogens.  They are plant pathologists, entomologists, nematologists, weed scientists, and other plant scientists who work diligently to mitigate the impact of endemic, emerging, and exotic pathogens and pests that attack agricultural, forest, and landscape plants in the United States.

Conservation science is a broad, deep field that’s growing all the time. To help people brush up on conservation practices and learn about new technologies, USDA’s Natural Resources Conservation Service (NRCS) offers hundreds of free conservation webinars from its online Science and Technology Training Library.

Available live or on-demand, these webinars also count as Continuing Education Units for many different certifying organizations and programs. Read more »

Where Passion Meets Purpose: The Snow Survey

Hydrologist Randy Julander

Hydrologist Randy Julander has been managing Utah’s snow survey program for the past 24 years.

“To say I enjoy my job is an understatement,” said Hydrologist Randy Julander. “Monday is my favorite day of the week, because I get to go back to work.”

As the Snow Survey Data Collection Officer in Utah, Julander’s job is a mix of science, adventure and artistry. He weaves information from data. “Data are just numbers on a page; but information – now that’s something meaningful, something that informs decision makers,” he explained. Read more »

Genomics and Precision Agriculture: The Future of Farming

High-resolution data such as these are used by scientists to optimize crop performance in specific environmental conditions.

For nearly 400 years, Thanksgiving has been a time in North America when families come together to celebrate food and agriculture. As we reflect on yet another year, agricultural scientists at USDA continue to keep a wary eye on the future. At the end of what may be the hottest year on record, a period of drought has threatened the heart of one of the most important agricultural production zones in the United States. Water demands are increasing, and disease and pest pressures are continually evolving. This challenges our farmers’ ability to raise livestock and crops.  How are science and technology going to address the problems facing our food supply? 

To find answers, agricultural scientists turn to data—big data.  Genomics, the field of science responsible for cataloging billions of DNA base pairs that encode thousands of genes in an organism, is fundamentally changing our understanding of plants and animals.  USDA has already helped to fund and collect genomes for 25 crop plant species, important livestock and fish species, and numerous bacteria, fungi, and insect species related to agricultural production. Other USDA-supported research projects expanding these efforts are currently underway, including genome sequencing of 1,000 bulls and 5,000 insect species in the i5K initiative. But classifying and understanding DNA is only part of the story. Read more »

A Commitment to Scientific Integrity

USDA and its scientists are dedicated to excellence, transparency, and cutting-edge scientific research.

USDA is one of the world’s leading scientific research institutions for agriculture, food and nutrition. We also have the largest forestry research resource in the world. At just one USDA agency – the Agriculture Research Service – more than 2,000 scientists publish more than 4,000 research papers each year in peer-reviewed journals on their work to ensure high-quality, safe, and sustainable food and other agricultural products. This work continues year after year, and the volume and quality of our research is particularly impressive when you consider that overall funding for both public and private spending on food and agriculture research has been stagnant for many years.

Our research extends from the farm field to the kitchen table, and from the air we breathe to the energy that powers our country.  Recent work by our researchers has produced a way to use radio frequencies to kill harmful salmonella in eggs; gene silencing technology that controls mosquito populations without harming pollinators; and a new soil nitrogen test that reduces fertilizer application amounts, reduces costs for farmers, and benefits the environment.
