ARS, NASA Join Forces To Monitor Earth’s Water Supply

Scientists with the USDA Agricultural Research Service (ARS) have teamed up with NASA to use satellites to monitor the water cycle on Earth, specifically “evapotranspiration” — the amount of water that enters the atmosphere through evaporation and transpiration from plants. Transpiration occurs during photosynthesis when plants take up carbon dioxide and release oxygen. That information is especially important for farmers …

Scientists Bring in Arch Enemy to Deal With Brown Marmorated Stink Bug

A tiny wasp may be the solution for managing an agricultural pest causing major economic damage to fruit, vegetable, and field crops in North America and Europe. Agricultural Research Service (ARS) scientists are currently studying Trissolcus japonicus, commonly known as the samurai wasp, to see if this parasitoid wasp is the right biological control agent for reducing brown marmorated stink bug (Halyomorpha …

Breeding Honey Bees for Adaptation to Regionalized Plants and Artificial Diets

Honey bees could be intentionally bred to thrive on plants that are already locally present or even solely on artificial diets, according to a recent U.S. Department of Agriculture Agricultural Research Service (ARS) study. ARS researchers found individual bees respond differently to the same diet and that there is a strong genetic component involved in how they respond to nutrition. This …

New Food Freezing Concept Improves Quality, Increases Safety and Cuts Energy Use

Shifting to a new food freezing method could make for safer and better quality frozen foods while saving energy and reducing carbon emissions, according to a new study by U.S. Department of Agriculture’s Agricultural Research Service (ARS) and University of California-Berkeley scientists. “A complete change over to this new method of food freezing worldwide could cut energy use by as …

Microalgae is the Bee’s Knees

We love to eat the honey that honey bees produce, but what do honey bees eat? The usual answer to this question is nectar and pollen. However, malnutrition in honey bees – a major reason why they’re growing more susceptible to pathogens, parasites, and pesticides – is a growing issue in the world of agriculture. This problem is exacerbated by …

Scientists Serve Up Vaccine Cocktail for Protecting Cattle from Disease

Scientists with the Agricultural Research Service (ARS) have developed a new experimental vaccine to protect cattle from the bacterium that causes Johne’s disease, Mycobacterium avium subsp. paratuberculosis (MAP). Johne’s disease, also known as paratuberculosis, is a chronic intestinal disorder that can cause diarrhea, weight loss, poor health and sometimes death in afflicted cattle. In the United States, Johne’s disease is …

ARS Scientists Develop Prediction Technologies to Reduce Soil Loss

Agricultural Research Service scientists designed seven of the top ten—13 of the top 25—most used predictive technologies/simulation models that are reducing the loss of soil to erosion around the world, according to a recently published study. Although originally developed for cutting down soil losses due to erosion from agricultural practices, today these models also are reducing soil loss from erosion …

Piglets Pay the Price of Mom’s Heat Stress

Piglets born to heat-stressed sows may carry the burden of their mom’s discomfort later in life in the form of health complications and diminished performance. Now, this so-called “in utero heat stress” may also hypersensitize the piglet’s immune system, potentially doing more harm than good to the young animals, a team of Agricultural Research Service (ARS) and university scientists has …

Good Bacteria Could Contribute in Fight Against Pathogens in Beef Processing Facilities

Disease-causing bacteria like Escherichia coli O157:H7 and Salmonella enterica could survive sanitization in beef processing facilities. Scientists and collaborators in the United States Department of Agriculture’s (USDA), Agricultural Research Center (ARS) are investigating how this happens while also seeking approaches to solve the problem. E. coli O157:H7 (a Shiga toxin-producing E. coli) and S. enterica are two disease-causing bacteria (pathogens) associated with foodborne illnesses in the United States. …

An Organic Alternative to Combatting Spotted Wing Drosophila

Scientists from the Agricultural Research Service (ARS) are working to understand how something can be equally effective as both a government-approved food additive and as a pesticide. Methyl benzoate is a naturally occurring compound produced by plants. The U.S. Food and Drug Administration long ago approved methyl benzoate for human use; its fruity and floral aroma makes it a staple …
