No matter what part of the country you grew up in, most of us have fond childhood memories of the wildflowers that sprung up each year around our homes, parks and roadsides.
For many, this fondness has carried into our adult years. This week, we celebrate National Wildflower Week as a way to share our interest and to increase public awareness for wildflowers in the landscape.
The beauty of wildflowers can indeed stir up memories of a certain place or time. But the wildflowers that are native to a particular place also serve an important function in the ecology of that place. Read more »

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 the USDA’s rich science and research portfolio.
When you think of agriculture do you think of science and engineering? You should! Farmers are some of our original scientists, tinkering with plant varieties and farming techniques to find ways to reliably grow food. At USDA, we still do that kind of research in a never-ending effort to find better ways to produce food, fuel, and fiber. We also do a lot of research you might not think of when you think about agriculture: from forensic genetic analysis to track down unwanted pests to figuring out how to turn spent grain from distilleries into biodegradable kitty litter.
On April 26-27, the 3rd Annual USA Science and Engineering Festival took over the Walter E. Washington Convention Center in Washington, D.C. Over 325,000 people came out to celebrate discovery and innovation through over 3,000 hands-on activities and 150 performances and lectures. USDA pulled all of the stops to show our geeky side and hopefully convince a few young booth visitors to consider agriculture when they think about careers in science. Read more »

How do you find something that doesn’t want to be found – something that has evolved to be cryptic, elusive, and stealthy? That is the question asked of APHIS geneticist Dr. Antoinette Piaggio. She and others at the National Wildlife Research Center (NWRC) – the research arm of the APHIS Wildlife Services program – are investigating new ways to track and locate invasive Burmese pythons.
Burmese pythons have made a home in Florida competing with and feeding on native wildlife. Experts agree that new tools and techniques are crucial to monitoring and controlling the spread of this elusive snake.
“Burmese pythons are semi-aquatic and can be very hard to detect given their elusive nature and cryptic coloration,” states Piaggio. “We’ve developed a new detection method that uses environmental DNA, thereby eliminating the need for seeing or handling snakes.” Read more »

California is the “bread basket” of American agriculture. In 2012, California’s 80,500 farms and ranches produced a record $44.7 billion in produce, dairy, and meats. With more than 400 crop varieties grown in the State, California produces nearly half of all U.S. grown fruits, nuts and vegetables.
To help ensure this basket stays full, the California Department of Food and Agriculture (CDFA) partners with APHIS Wildlife Services (WS) to address wildlife damage issues to agriculture. Some of the more recent work involves the development of repellents to protect crops from birds. Read more »
At the APHIS Otis Lab in Massachusetts, employees conduct research for several APHIS forest pest emergency response and eradication programs, including Asian longhorned beetle (ALB), Asian gypsy moth (AGM), emerald ash borer (EAB), and Sirex noctilio woodwasp.
In addition to the existing science-based eradication protocols for fighting an Asian longhorned beetle (ALB) infestation, such as surveying trees and removing infested ones, the USDA’s Animal and Plant Health Inspection Service (APHIS) relies on on-going research to not only improve current protocols, but also to develop new ones.
APHIS’s Center for Plant Health Science and Technology continues research to develop attractant-baited traps designed to lure and capture adult insects. The attractants include plant odors and pheromones, which are naturally occurring chemicals created and used by insects to communicate with each other. These attractants are used to lure beetles to traps that are hung on trees that the beetle will attack. Traps can aid in early detection of insects in areas where survey staff may not be working. When the traps are checked by staff members and a beetle is found, nearby trees may be surveyed to determine if they are infested. This year, the traps will be placed in the spring and early summer in strategic locations in all three ALB-affected states: New York, Massachusetts, and Ohio. APHIS is also working with the U.S. Forest Service and Penn State University on their research with similar ALB traps. Read more »
While most people have a mental image of research that involves scientists in lab coats, bubbling test tubes and beakers, and technical language that can seem complex, much of the groundbreaking research conducted by USDA scientists actually ends up on your plate, in your home, or on your back. Their discoveries in the lab truly translate into science you can see.
For example, many of us make a conscious effort to eat healthier and cut calories, but it can be tough when faced with a favorite snack, like French fries. USDA scientists have figured out a way to make French fries healthier. Before frying, scientists exposed potato strips to a few minutes of infrared heat. This forms a crispy outer shell on the outside of the fries, which helps to reduce their oil uptake and ultimately reduces calories per serving. If adopted commercially, this method is great news for both food processors and our waistlines. Read more »
