Clarksville, TN – For years, the area behind Ellington Hall was considered one of the least attractive spots on the Austin Peay State University (APSU) campus. The land, surrounded by sidewalks and abutting loading zones and parking lots, sloped downward into a wide, unsightly bowl that flooded during heavy rains.
Washington, D.C. – NASA states that understanding the effects of gravity on plant life is essential in preparing for human exploration beyond low-Earth orbit.
The ability to produce high-energy, low-mass food sources during spaceflight will enable the maintenance of crew health during long-duration missions while having a reduced impact on resources necessary for long-distance travel.
Pasadena, CA – The Red Planet is an inhospitable world. NASA says growing crops on Mars is far easier in science fiction than it will be in reality. Among other challenges, subzero temperatures mean water can persist on the surface only as ice, and the planet’s atmosphere offers little protection to plants (or people) from the Sun’s radiation.

Washington, D.C. – NASA says when plants take in too much energy, they don’t get fat – they lighten up. They absorb more sunlight than they need to power photosynthesis, and they get rid of the excess solar energy by emitting it as a very faint glow.
The light is far too dim for us to notice under normal circumstances, but it can be measured with a spectrometer. Called solar-induced fluorescence (SIF), it’s the most accurate signal of photosynthesis that can be observed from space.
That’s important because, as Earth’s climate changes, growing seasons worldwide are also changing in both timing and length.

Pasadena, CA – Doctors learn a lot about their patients’ health by taking their temperature. An elevated temperature, or fever, can be a sign of illness. The same goes for plants, but their temperatures on a global scale are harder to measure than the temperatures of individual people.
That’s about to change, thanks to a new NASA instrument that soon will be installed on the International Space Station called ECOSTRESS, or ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station. ECOSTRESS will measure the temperature of plants from space. This will enable researchers to determine plant water use and to study how drought conditions affect plant health.
Mono-unsaturated fats from plants, not animals may reduce risk of death from heart disease and other causes
American Heart Association Meeting Report
New Orleans, LA – Diets rich in mono-unsaturated fatty acids from plants were associated with a lower risk of dying from heart disease or other causes compared to diets rich in mono-unsaturated fats from animals, which were linked to a higher risk of death from heart disease or other causes, according to preliminary research presented at the American Heart Association’s Epidemiology and Prevention | Lifestyle and Cardiometabolic Health Scientific Sessions 2018, a premier global exchange of the latest advances in population based cardiovascular science for researchers and clinicians.
Tennessee Department of Agriculture says Buy Locally Grown Flower and Vegetable Plants With Confidence
Nashville, TN – Are you a gardener gearing up for the growing season? Local farmers markets, on-farm greenhouses, and retail garden centers are filling with gorgeous flowers and vegetable plants that promise bountiful harvests.
Experienced plant lovers know that sometimes plants can look beautiful in the store, but will soon wilt once planted. Worse, they can bring bugs and blights into your home.

Houston, TX – When plants on Earth search for nutrients and water, what drives their direction? Very simply, gravitational force helps them find the easiest path to the substances they need to grow and thrive. What happens if gravity is no longer part of the equation?
Botanists from Ohio Weslyan University leverage the microgravity environment of the International Space Station to study root growth behaviors and sensory systems in an investigation known as Gravity Perception Systems (Plant Gravity Perception).

Greenbelt, MD – Life. It’s the one thing that, so far, makes Earth unique among the thousands of other planets we’ve discovered. Since the fall of 1997, NASA satellites have continuously and globally observed all plant life at the surface of the land and ocean.
During the week of November 13th-17th, NASA is sharing stories and videos about how this view of life from space is furthering knowledge of our home planet and the search for life on other worlds.

Florida – Early Friday morning, astronauts onboard the International Space Station were busy at work, harvesting three varieties of leafy greens from the Veggie growth chamber and installing the next generation of plant research – the high-tech Advanced Plant Habitat.
The Veggie plant growth team kicked it up a notch with their sixth round of crops grown aboard the International Space Station with experiment VEG-03D. For the first time, three different plant varieties are simultaneously growing in the Veggie chamber.
