This post is part of the Science Today feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research portfolio.

Breadfruit has been a hit in Melanesia, Micronesia and Polynesia for more than 3,000 years because of its many pluses:  This tropical staple food crop is plentiful and packed with nutrients.  It’s hailed by some as a possible solution to world hunger, but it could play a totally different—but equally important—role in saving lives.

Scientists with USDA’s Agricultural Research Service (ARS) have found that breadfruit flowers contain three chemicals that work wonderfully for repelling flying insects, including mosquitoes.  In Hawaii and other regions, people have known for years that burning dried clusters of the flowers, known as “male inflorescences,” can keep bugs at bay.

Uh, oh! El Día de Acción de Gracias está a la vuelta de la esquina. Usted compró un pavo en venta el año pasado y lo congeló. Usted sabe que está inocuo debido a que recientemente leyó que era seguro indefinidamente y que mantiene su calidad por un año. Pero lo que usted no sabe es cómo y dónde descongelarlo.

Primero que todo, el pavo no debe ser descongelado en las encimeras o en agua caliente. Estos métodos NO son considerados seguros y pudieran provocar enfermedades transmitidas por los alimentos. En adición, nunca descongele el pavo en el garaje, sótano, auto, en exteriores o en el balcón. El pavo, así como cualquier alimento perecedero, debe mantenerse a temperaturas inocuas durante “la gran descongelación”. Sino, en cuanto el pavo comience a descongelarse a temperaturas mayores a 40*F, las bacterias presentes antes de la congelación pueden comenzar a multiplicarse.

Uh, oh! Thanksgiving is right around the corner. You bought a turkey on sale last year and froze it. You know it’s safe because you recently read that frozen turkeys are safe indefinitely and keep good quality for a year. But what you don’t know is how or when to thaw it.

First of all, turkey should never be thawed on the counter or in hot water. These methods are NOT considered safe and may lead to foodborne illness. Also, never thaw a turkey in a garage, basement, car, on the kitchen counter, outdoors or on the porch. Turkey, as any perishable food, must be kept at a safe temperature during "the big thaw." If not, once the turkey begins to thaw and becomes warmer than 40 °F, bacteria present before freezing can begin to multiply.

You’re invited to the USDA Harvest Festival on Friday, November 22 from 10 a.m. to 2 p.m. Come celebrate the end of the growing season in the People’s Garden and at the USDA Farmers Market. Take advantage of the last opportunity of the year to shop the outdoor USDA Farmers Market located along 12th Street, SW in between Jefferson Drive and Independence Avenue in Washington, DC.

The day will be filled with fun activities and educational demonstrations that are free and fun for the whole family. Here’s a list of the planned events:

The Forest Service recently celebrated the opening of the Milwaukee Rotary Centennial Arboretum at the Urban Ecology Center - Riverside Park in Milwaukee.

In 2012, the USDA Forest Service, Eastern Region proudly joined Urban Ecology Center partners – the Rotary Club of Milwaukee, Milwaukee County Parks and the River Revitalization Foundation – in this exciting project.

The designation as a Forest Service’s Children’s Forest adds an element of wonder to the space. As visitors explore this outdoor play space, they will discover interpretive stations to help them forge a deeper connection with nature. Only one of 22 children’s forests throughout the country, this Milwaukee forest is one of only three located within a major urban area.

At USDA, we know that local and regional food systems are an important part of America’s diverse agriculture sector.   Local and regional food is a multi-billion dollar market opportunity for America’s farmers, ranchers and food businesses. From the produce vendor at one of the nation’s 8,100 farmers markets to the operating  220 food hubs across America to the robust farm to school activities in each state,  the expanding market opportunity for local and regional food continues to gain momentum

USDA stands ready to aid and assist America’s farmers and ranchers who want to participate in this growing sector. We’ve been coordinating our work via the Know Your Farmer, Know Your Food Initiative. However, our ability to continue supporting the local and regional food marketplace is at stake without the passage of a Food, Farms and Job Bill.

The holiday season has finally arrived! It’s time to find your favorite family recipes and start cooking! While many of our favorite dishes help us to remember and celebrate special times, choosing healthier options can be a challenge. Let MyPlate help you find solutions with “MyPlate Holiday Makeovers.” During our eight-week series, you’ll find ways to celebrate the season with great new resources such as recipes, a new infographic, and tips for preparing your holiday feast.

Last week, researchers from Michigan State University, Oakland University, Blue Cross Blue Shield of Michigan, and the Michigan Department of Education came out with a new study showing that when schools offer healthier snacks in vending machines and a la carte lines, students’ overall diets improve. Students in schools that offered healthier snacks consumed more fruits, vegetables and whole grains, and not just at school—at home, too.

This is encouraging news for schools and school nutrition professionals as they begin implementing the Smart Snacks in School standards, which will ensure that students are offered healthier food options during the school day. Smart Snacks in School requires more whole grains, low fat dairy, fruits, vegetables and leaner protein, while still leaving plenty of room for tradition, like homemade birthday treats and bake sale fundraisers.

With Thanksgiving right around the corner, it is the perfect time to learn more about the quality grade standards for poultry products and the “Grade A” shield you might find on the label of your family’s main dish.  Most consumers are familiar with the USDA beef grades – Prime, Choice and Select.  But did you know USDA has similar grade standards for Poultry products?

The USDA grade shields are reputable symbols of quality American poultry products.  Large-volume buyers such as grocery stores, military institutions, restaurants, and even foreign governments use the quality grades as a common “language” within the poultry industry, making business transactions easier.

Earlier this year, approximately 80 people oohed and ahhed as meteors streaked across the sky from all directions over Shasta Lake during the Perseid meteor showers. In partnership with the Shasta Astronomy Club, the Shasta-Trinity National Recreation Area provided visitors with expert information on celestial objects and events and a guided tour through the night sky.

This weekend, you have an opportunity to do the same when the 2013 Leonid meteor shower peaks on the night of Saturday, Nov. 16 into the early morning hours of Sunday, Nov. 17.  According to NASA, Leonids are bits of debris from Comet Tempel-Tuttle. Every 33 years the comet visits the inner solar system and leaves debris in its wake. Many of these have drifted across the November portion of Earth's orbit. Whenever our planet hits one, meteors appear to be flying out of the constellation Leo.  Unfortunately for meteor watchers, this year a full moon will likely wash out all but the very brightest Leonids.
