Stainless Steel’s Appeal Stretches from the Kitchen to the Dairy Farm

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.

Stainless steel’s all the rage in gourmet kitchen design, but its appeal could soon extend well beyond the kitchen to the nation’s dairy farms, thanks to intriguing discoveries by Agricultural Research Service (ARS) scientists at the agency’s Animal Waste Management Research Unit in Bowling Green, Ky.

Perfecting the ‘Perfect’ Food

How does one improve upon perfection?  By definition, that’s an impossible task, but a team of scientists is working to help breeders of the “near-perfect” food so they can improve production around the world.

The Science of Autumn Colors

Like a lot of people, I remember being taught when I was young that the brilliant autumn foliage of deciduous trees was caused by the cold temperatures of autumn frosts.  I believed this until I became a horticulturist, studying the intricate system that plants use to prepare for winter’s harsh weather.  Where I work, at the U.S. National Arboretum, we grow about 10,000 different kinds of trees and shrubs and have an overwhelming variety of fall color right now.

Sly Red Fox Outed by Scientific Sleuthing

New research featured in the April/May 2011 issue of Science Findings, a monthly publication of the Forest Service’s Pacific Northwest Station, can assist efforts aimed at conserving potentially imperiled populations of the North American red fox. “When most people think of the red fox, they envision the ones that thrive in low-elevation, human-dominated landscapes,” said lead author Keith Aubry. “But there are other extremely elusive and rarely seen populations that live only in isolated alpine and subalpine areas in the mountains of the Western United States.”

DNA Research that can Assist with Understanding the Effects of Climate Change

In a scientific achievement that is important in planning for future climate scenarios, and for protecting some endangered animal species, U.S. Forest Service research geneticist Bryce Richardson and research ecologist Michael Schwartz, have sequenced more than 40 billion base pairs of DNA from 130 samples of plant,  animal and fungal species. The tree species were as diverse as tan oak, sugar pine and sagebrush.

This DNA sequencing is more than 12 times the amount of information in the human genome, which has about 3.3 billion base pairs. The massive undertaking, known as the Western Forest Transcriptome Survey, is a collaborative effort between four U.S. Forest Service research stations and four universities.

USDA Holds Plant Variety Protection Office Board Meeting

Innovation was the buzz word during the 2011 USDA Science and Technology Plant Variety Protection Office (PVPO) Board Meeting.

The PVPO, part of the Agricultural Marketing Service’s (AMS) Science and Technology Program, gives legal intellectual property rights, similar to patents, to breeders of new varieties of plants which are produced by seeds such as corn and soybean or by tubers such as potatoes. The program protects intellectual property rights by offering certificates to owners of unique plant varieties so that they can introduce them to the marketplace.  The board, made up of a diverse group of experts in the plant variety development field, met to discuss pressing industry matters and address how the PVPO conducts its business.

Human Ecology Mapping and “All-Lands” Conservation

U. S. Forest Service social scientist Lee Cerveny has carved out a special niche in the world of research. While her colleagues go into national forests and other protected areas to study things like trees and wildlife, she enters these natural environments to study humans – how they interact with and use a range of sites and resources.
