Grass is a big deal in football – a really big deal.  Nearly every day of the week, untold millions of people watch players step out onto lush, green fields painted with white.

All aspects of the game are tough. Even growing and maintaining a real turf grass field has its challenges, like freezing temperatures, rain, and damage from tackles and foot traffic.  So what type of grass can hold up to all that? Horticultural specialists and plant breeders throughout the land-grant university cooperative extension system, as well as USDA researchers from Agricultural Research Service, are working to answer that question.  USDA’s National Institute of Food and Agriculture supports their research with Hatch Act funding.

Did you know that NASA has a mini veggie farm at the International Space Station that grows lettuce? Every day, ground-breaking scientific research is taking place to improve food production practices in order to feed people on Earth and in space.

Earlier this week in USDA’s People's Garden, local 4-H and FFA students gathered to plant sister seeds to lettuce grown on the International Space Station, which will be harvested in about a month. By getting their hands dirty, students were able to ask questions about what it takes to grow food under a variety of conditions. This is particularly important as our nation’s farmers and ranchers look to feed a growing world population.

Happy National Farm to School Month! Every October, the USDA Farm to School team is overwhelmed with stories of how farm to school programs are affecting kids, producers, and communities. Having now made 221 grants to school districts and other entities across the country to pursue projects that bring more local foods into schools and teach kids about where their foods comes from, we experience a steady stream of encouraging stories throughout the year. Stories about local farmers proudly supplying grains for a district’s whole grain baked goods; stories about school food service staff dressing up like fruits and vegetables to encourage healthy eating; stories about kids growing beets in the school garden and then devouring them when they show up in the cafeteria. During Farm to School Month, these anecdotes proliferate--on social media, on blogs, and via news stories. They inspire us, amuse us, and sometimes even make us tear up, but they don’t unequivocally prove that these programs work. For that, we rely on studies and surveys, on journal articles and evaluation results.

Living memorials serve as a reminder of fathers and mothers, sons and daughters, brothers and sisters, neighbors and friends—but also of the power of community to reflect, rebuild and renew. Our research suggests that living memorials demonstrate the role of nature in contemporary times not only as a symbol, but as an innate and purposeful response to loss that calls forth a common humanity and compassion for others.

In other words, they demonstrate how people use nature to be resilient to loss.

Indigenous people of the Andes Mountains in South America have farmed the nuña bean (a.k.a. “Peruvian Popping bean”) as a staple crop for centuries. Its colorful, nutty-flavored seed is especially prized for its tendency to pop open when roasted—a cooking method that requires less firewood than boiling in fuel-scarce regions.

At the Agricultural Research Service’s Western Regional Plant Introduction Station in Pullman, Washington, plant geneticist Ted Kisha curates an edible dry bean collection that includes 91 accessions of high-altitude nuña beans grown by Andean farmers in Peru, the origin for this legume member of the Phaseolus vulgaris family.

U.S. Forest Service Research and Development celebrates a century of existence this year and while we don’t all get the opportunity to work directly with our researchers and scientists, we all benefit from their contributions.

We are extremely fortunate as an agency to have our own Research & Development branch. It has allowed us to not only develop the science that we need to do our jobs but also to apply it to our present and future initiatives. We are a science-based organization and many of the solutions to the challenges we face derive from the team’s work.

Food safety is a top priority for consumers, especially when it comes to the leafy greens in salads. Researchers at the University of Arizona have discovered natural methods to sanitize these vegetables using ingredients commonly found in the kitchen, such as oregano, cinnamon, and vinegar.

Plant extracts, essential oils, and organic sanitizers have all proved effective in killing bacteria on leafy greens and extending their shelf life. When emulsified in the water used to wash these leaves, the approach compares to (and sometimes even works better than) bleach or hydrogen peroxide.

Scientists from the University of Texas at El Paso (UTEP) are working with stakeholders to determine the course their research will take.  The result, they say, is better science that is more useful to end users – and the scientists learn a lot, too.

Rather than have their own science-based questions direct their research, Dr. Josiah Heyman and his research partner Dr. William Hargrove will let stakeholders – the actual users of their science – point the way.  According to Heyman, this “participatory approach” is science for the public’s sake, not for the scientists’ sake.  The two lead a multi-institutional, multi-national project that is tackling drought-driven water supply issues in the Southwest.

It can reach heights of 200 feet and live 500 years, and occupies landscapes across the western United States. Some say its bark has an unforgettable smell resembling vanilla or even cinnamon, and this tree is one tough cookie. It grows in a variety of soils and climates and survives fires that consume other species. It is also an ecologically and economically valuable tree that provides food, habitat and ponderous (heavy) lumber.

It is the iconic ponderosa pine. But the world is changing, and ponderosa pine is vulnerable to climate shifts, high-intensity wildfires and bark beetles — as well as development that replaces trees. To keep the ponderosa pine standing tall, researchers are looking for answers in its genes.

The release of the USDA’s 2014 Technology Transfer Report highlights the groundbreaking discoveries made by USDA researchers, who continue to push the envelope and come up with new and exciting innovations. The scientific advancements in knowledge and the creation of new technologies directly impact Americans in that they create safer environments and provide efficient solutions for a wide range of issues. Here are just four of the transformative innovations that can be found in the USDA Tech Transfer Report:
