How many of us have said this–”Yeah, I could definitely stand to lose a few pounds”–usually with a self-deprecating chuckle?

In reality, obesity is no laughing matter in the United States.  Did you know that an obese person spends over $1,530 more per year on health care than a person with normal weight spends according a 2010 report by the Congressional Budget Office?  Rates of childhood obesity in the U.S. have more than tripled in the past 30 years, and rates of adult obesity have doubled in that time.

Most of us accept that some services—such as waste water treatment and emergency response, for example—have an economic value. As citizens, we decide to support these services for our safety, security and comfort. And yet there are many other functions going on every day, all around the world, that are not directly supported but still enable our planet to maintain favorable living conditions for all living creatures—functions like bees pollinating our crops, forests absorbing excess carbon dioxide, or dung beetles breaking down animal wastes.

The U.S. Department of Agriculture (USDA) Bee Research Laboratory displays a live bee colony in a two-sided glass case at 2012 Smithsonian Folklife Festival, Thursday, June 28, 2012 on the National mall in Washington, D.C. One of the three themes this year is “Campus and Community.” It celebrates the 150 years of the USDA and the Land-Grant University System. The USDA and the Land-Grant system extend education across the country, contributing to American agriculture success and rural prosperity. “Campus and Community” has demonstrations, discussions, hands-on activities, and entertainment to that showcase the many ways that this partnership works to improve American agriculture and rural life.

This week, representatives from USDA have been down on the National Mall, staffing hands-on exhibits about food safety, bioenergy and even bees.  Agricultural Research Service (ARS) scientists have, for years, been studying Colony Collapse disorder (CCD), which has been attacking honey bee colonies since 2006.

At 11:00 am today, Agriculture Deputy Secretary Kathleen Merrigan, will be helping open the 2012 Smithsonian Folklife Festival, hosting visitors from around the world who will come to the Mall in Washington, D.C. for this annual event.  The Department of Agriculture (USDA) is the only federal agency lucky enough to be located right on the Mall, and this year we’re also honored to be a part of the Folklife Festival, celebrating our 150-year partnership with the Land Grant University system. “Campus and Community: Public and Land Grant Universities and USDA at 150” is one of the three themes highlighted at the Festival this year.

USDA scientists, agricultural experts and speakers will be partnering with representatives from 29 Land Grant Universities (LGUs) to showcase all the great work we do together to support agricultural production, education and rural communities across America.  USDA works hand-in-hand with Land Grant and public universities to put research into action locally, regionally and globally.

Painting by Taina Litwak of a new species of tiny parasitic wasp in the genus Perischus. Done in 2011 for Dr. Matt Buffington. The painting starts with a pencil drawing done through the microscope of a dead pinned specimen. Details for this painting were included which only are visible in scanning electron microphotographs, as the species is so very small. The painting itself is done digitally in Adobe Photoshop. The species was first collected in South America in 2010 and is involved with parasitizing a species complex of flies which lay eggs in cucurbit plants (melon, cucumber and squash family).

I am a scientific illustrator on staff with the Systematic Entomology Lab, in the Plant Sciences Institute, ARS, located in the Smithsonian Institution’s Museum of Natural History. Last week, I had the pleasure of meeting Secretary Vilsack, who was interested in several of my paintings of newly described species of insects that I entered in the U.S. Department of Agriculture’s (USDA) 2012 Employee Art Exhibit.  As I answered his questions, it occurred to me that people may not associate USDA with artistry or illustration and that my job as “Scientific Illustrator” may in fact seem unusual to many.

Although corn is perhaps the most familiar player on the American biofuel scene, scientists with USDA’s Agricultural Research Service (ARS) say in the long run, barley and its byproducts could prove to be a viable renewable fuel option. Read more »
