Fresh corn and homegrown tomatoes are as much a part of the traditional American scene as apple pie.  Scientists with USDA’s Agricultural Research Service (ARS) have applied cutting-edge technology to learn more about these longtime favorites and, in the long run, make them even better.

As part of an international consortium of 300 researchers, ARS scientists recently sequenced the genome of the domesticated tomato.  This achievement is expected to lower production costs and speed up efforts to improve the United States’ $2 billion tomato crop, making the plant better equipped to combat the pests, pathogens, drought and diseases that now plague growers. That’s good news for tomato fans, because since 2000, Americans have been consuming an average of 19 pounds of tomatoes per person every year.

Are you an organic grain farmer or thinking of becoming one?  Or maybe you’re wondering about strategies for improving soil quality or using less pesticide?  If so, then you could benefit from research and outreach conducted by staff at the Sustainable Agricultural Systems Laboratory (SASL) at USDA’s Agricultural Research Service (ARS) in Beltsville, MD.

USDA’s National Institute of Food and Agriculture has funded two projects through the Organic Agriculture Research and Extension Initiative (OREI) that are helping ARS-SASL reach organic producers.  Both projects are setting a high standard for extension activities.

Sustainability is an important issue in government, with city planners, state agencies, and the federal government all talking about ways they can adapt to climate change, population growth, and the increasing pressures on natural resources that are coming as the century unfolds.  So, in order to further the conversation about sustainability in the federal government, the National Academy of Sciences held a two and a half day symposium on science, innovation, and partnerships for sustainability solutions on May 16-18, in Washington DC.

People often get confused when observed weather patterns run contrary to climate projections.  For instance, those living in the Mid-Atlantic States hear from experts that the region has now moved into a dry savanna-like climate zone, but yet two winters ago over 40 inches of snow fell in a single month.  But weather is highly variable regardless of the state of the climate.  Individual weather events like this one are different than "climate," which refers to long-term trends over decades.  And further, climate change could produce more extremes at both ends of the weather spectrum even while a region shifts into a seemingly contrary climate state.

In an attempt to make science and technical concepts of projecting climate change clearer to the public, the U.S. Forest Service has published a report simplifying complex information and resources.

To many of locals in western North Carolina, they’re called wild leeks.  Some call them ransoms and still others call them wood garlic because of their pungent smell. Nevertheless, ecologists simply call them ramps. This native plant has been useful to humans since inhabiting the eastern regions of the U.S. and Canada.  Still today, locals harvest ramps for food, medicinal preparations, and to sell at markets and spring festivals.

Many teachers use creative methods to keep their students engaged in the curriculum they are teaching. Some methods work far better than others. For one group in Hawaii, teachers are using gardening to boost their science, technology and math classes, while placing an emphasis on Hawaii’s need for more experiential science learning related to agriculture and sustainability.

Recent warming of terrestrial climates combined with decreased stream flows has raised concerns about possible increases in stream temperatures in the Pacific continental United States. Loss of cold, clean water in the region has major implications for human use and for sensitive coldwater fishes, such as salmon and trout. In a joint project, the U.S. Geological Survey (USGS), U.S. Forest Service’s Pacific Northwest Research (PNW) Station, and Oregon State University (OSU) researchers assessed the climate effects on cold water in low and high human-influenced sites using long-term stream temperature data from the USGS and the Forest Service.

April, the springboard to warm, sunny weather, is National Minority Health Month—a good time to focus on the sun, vitamin D insufficiency for African-Americans, and the ways that monitoring its intake have improved.

Vitamin D is primarily produced by exposure to the sun’s ultraviolet rays. However, African-Americans have more melanin in their skin, resulting in the reduction of the body’s ability to make the vitamin from sun exposure.

To help those in need make ends meet, the Federal Government offers a variety of assistance programs.  Some provide cash, but more offer in-kind assistance such as subsidized rents or assistance with home energy bills. USDA provides eligible households with in-kind assistance in the form of Supplemental Nutrition Assistance Program, or SNAP, benefits to buy groceries (formerly called the Food Stamp Program). But these benefits, and other in-kind assistance, are not counted as income when the Census Bureau calculates official poverty rates.  Not accounting for these benefits understates the resources of U.S. families who receive them and masks the greater relative hardship of those who do not.
