Windows XP was recently retired along with the iconic photo of a verdant green field on rolling hills that was the operating system’s default wallpaper.

This photo, called “Bliss,” had puzzled me for some time as it looked so familiar.

Nearly 46 years ago, Echo Summit, on the forest 10 miles west of South Lake Tahoe in California, was the site of a high-elevation training facility. At an elevation of 7,377 feet, the 400-meter oval track, carved out of a stand of pine trees, was designed to prepare athletes for high-altitude conditions that were similar to those in Mexico City, where the Games would be held. The site was later declared a California historic landmark.

Today, in a major step to advance the President’s Climate Data Initiative, the Obama administration is inviting leaders of the technology and agricultural sectors to the White House to discuss new collaborative steps to unleash data that will help ensure our food system is resilient to the effects of climate change.

More intense heat waves, heavier downpours, and severe droughts and wildfires out west are already affecting the nation’s ability to produce and transport safe food. The recently released National Climate Assessment makes clear that these kinds of impacts are projected to become more severe over this century.

Ramadan will end this week.  This month of fasting concludes with Eid ul-Fitr, and on this festive day it is forbidden to fast. Those commemorating this holiday attend prayer, visit with family and friends, and celebrate. While traditions vary, one component stays the same – FOOD. If you plan on celebrating this “Festival of Breaking the Fast” follow the four simple steps for food safety to keep your loved ones foodborne illness-free: clean, separate, cook and chill.

During Eid ul-Fitr, observers visit the homes of family, friends and neighbors. As with most family gatherings and celebrations, children often play while adults talk. Also like most family gatherings and celebrations, food is usually served, in the form of a small snack or a large meal. As you and your family make your holiday visits, make sure your children clean their hands before they enjoy the day’s treats.

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.

How would you like to learn more about your personal health while contributing to science as a volunteer in a human nutrition research study?

Seventeen years ago, I saw an ad for such a study. I attended an information session to learn more, applied and was accepted. Looking back, it was a positive experience for me, and I’d do it again if I could.

Every time I explore a farmers market I become a kid again. It brings back memories of snacking on sun-ripened figs from my backyard with dad or squeezing for perfectly ripe tomatoes at the neighborhood farm stand with mom. The existence, uniqueness and vibrancy of farmers markets can be a positive experience full of exploration and deliciousness for any age. It sure is for me.

USDA is committed to helping all of America’s children, families and communities not only have access to healthy affordable food, but form positive associations with these healthy foods. Visiting a farmers market offers a unique learning environment where you can be introduced to fresh, local produce; a variety of sights, tastes and smells; as well as meet neighbors, farmers and vendors.

The Molokai Land Trust (MLT) is a partner of USDA’s Natural Resources Conservation Service in its efforts to restore native landscapes on the Island of Molokai in Hawaii. MLT and NRCS have partnered together on many projects, including the one highlighted in this post. Justin Fritscher, NRCS.

The endangered wedge-tailed shearwater and other at-risk plant and wildlife species find sanctuary in the coastal dune ecosystem of Hawaii. But like many native ecosystems in the state, this one suffers from the effects of human development and invasive plants and animals.

In an effort to restore ecosystems in the region, the Molokai Land Trust, or MLT, on the Island of Molokai, is working to restore and replant native vegetation and remove threats from invasive species.

On May 30, the double-hulled voyaging canoe Hōkūle‘a set sail from the Hawaiian Islands on a more than 50,000-mile, 26-country journey around the world. The crew’s mission: to spread the word about the importance of world conservation.

The dual-masted, 62-foot Hōkūle‘a, along with her escort the voyaging canoe Hikianalia, will travel to Tahiti, New Zealand, Indonesia, South Africa around Cape Horn, Brazil and Florida, and through the Panama Canal before heading to Rapa Nui (Easter Island). At Rapa Nui, younger crewmembers will take the helm and sail back to Hawaii.

These days, it seems like it’s easier than ever to turn a good idea into reality. This is the era of Kickstarter, where entrepreneurs can connect with potential investors at the click of a button.

Of course, it takes more than money to grow an idea. It takes an atmosphere that fosters creativity and rewards innovation. And at a deeper, less obvious level, it requires strong, secure infrastructure—roads and bridges, but also internet access and community facilities like hospitals and schools—that improves connectivity and access to information, moves products to market, and makes communities competitive and attractive to new businesses and investments.

In deep East Texas, pine trees are king. Towering pines line the roads and blanket the rolling countryside and national forests. Loblolly and slash pine dominate the landscape in contrast to the area’s historic longleaf pine trees that once reigned.

The reduced number of longleaf pines has not gone unnoticed by landowners and conservationists. In response to the striking loss of longleaf pine trees from Texas to Florida, USDA’s Natural Resources Conservation Service (NRCS) launched the national Longleaf Pine Initiative, which provides technical and financial assistance for conservation practices that help restore longleaf pine forests and enhance existing pine stands.
