Thanks to the efforts of a dedicated science teacher from New Jersey, a valuable piece of soil science history is now available for viewing and research among the special collections at USDA’s National Agricultural Library (NAL) in Beltsville, Maryland.

Jill Guenther, who has taught Earth and space science for 29 years, discovered the antique soils collection tucked away in a classroom cabinet. “I knew it was something special, and I wanted to use it as a display when teaching erosion and conservation issues,” she 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 »

USDA’s National Agricultural Library (NAL) has launched a fascinating online collection of historical diet and nutrition publications issued by the U.S. Government. The Historical Dietary Guidance Digital Collection (HDGDC) combines more than 900 documents representing over 100 years of history. Through this digital collection, users can explore the evolution of American food, diet and nutrition, reflecting the most current science of the time. This unique resource is the first of its kind to offer comprehensive online access to historical government nutrition publications. Read more »

Food Safety is Everybody’s Business

Consumers should be vigilant about handling and cooking food properly—food safety is everybody’s business.

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.

USDA’s summer road trip may have come to an end, but many folks are still firing up the grills as summer winds down. With that, consumers still need to be conscious of food safety—from checking temperatures of grilled meat to discarding perishables that have been sitting out too long. A quick U-turn on our road trip explores USDA’s Agricultural Research Service (ARS) food safety research program, which addresses complex food safety challenges by developing scientific information and new technologies to control foodborne contaminants.

Frost on the Chickens

A phone call to USDA’s National Agricultural Library (NAL) seeking the original magazines with Robert Frost’s first published prose has now given rise to the library’s newest online exhibit. But why did a Frost aficionado call an agricultural library looking for these?

Because, before Robert Frost became ROBERT FROST, he was a chicken farmer with 300 white Wyandotte hens from 1900 to 1909 in Derry, New Hampshire. However, Frost wasn’t ever really a good fit for farming—he had serious hay fever, for one—and coops and eggs were a long way from four Pulitzer prizes for poetry. Read more »

Meet Your Wellness Goals in the New Year with the USDA DRI Calculator for Healthcare Professionals App

New “USDA Dietary Reference Intakes (DRI) Calculator for Healthcare Professionals” app allows users to keep track of nutrient calculations and recommendations based on the DRI values.

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.

The USDA National Agricultural Library’s (NAL) Food and Nutrition Information Center (FNIC) today launched its mobile application, or “app,” which calculates Dietary Reference Intakes (DRIs).  The “USDA Dietary Reference Intakes (DRI) Calculator for Healthcare Professionals” app allows users to keep track of nutrient calculations and recommendations that are based on the DRI values in a more convenient and user-friendly format. Through this new app, healthcare professionals can save time in the nutrition care process for patients and clients, while having access to credible nutrition guidance.

The National Academy of Science’s Institute of Medicine first developed the DRIs in the mid-1990s. DRIs are recommended amounts of each nutrient a healthy person should consume to prevent deficiency or harmful health effects. Initially presented in tables, this information allows healthcare professionals to use the DRIs to assess and plan diets for groups or individuals. For example, if you are a female between 19 and 50, your registered dietitian or doctor may recommend that you increase your dairy consumption to meet the 1,000mg/day calcium recommendation outlined in the DRIs. The DRIs are also used in policy-making such as setting calorie and sodium guidelines for healthy school lunches. Read more »
