New discovery about the formation of new brain cells
The generation of new nerve cells in the brain is regulated by a peptide known as C3a, which directly affects the stem cells' maturation into nerve cells and is also important for the migration of new nerve cells through the brain tissue, reveals new research from the Sahlgrenska Academy published in the journal Stem Cells. view more (2009-11-24)

Hybrid bluegrasses analyzed for use in transition zone
The transition zone can be one of the most challenging places to maintain high-quality turfgrass; changeable growing conditions in these regions often prove too hot for some grasses and too cold for others. Finding turfgrass that thrives in these challenging environments can be perplexing for turf management professionals and homeowners alike. view more (2009-11-05)
For African violets, 'hands off' means healthier
African violets have a mixed reputation. Their delicate, colorful flowers and furry, soft leaves make them a favorite among home gardeners and growers. But the striking plants are often regarded as temperamental: a precise recipe of light, moisture, warm temperatures, high humidity, and fertilizer is required to encourage african violets to grow... view more...

Tsunami evacuation buildings: another way to save lives in the Pacific Northwest
Some time soon, a powerful earthquake will trigger a massive tsunami that will flood the Pacific Northwest, destroying homes and threatening the lives of tens of thousands of people, says Yumei Wang, a geotechnical engineer at the Oregon Department of Geology and Mineral Industries in Portland. view more (2009-10-20)
Stanford study identifies cellular mechanism that causes lupuslike symptoms in mice
Macrophages, the scavenger cells of the body's immune system, are responsible for disposing of dying cells. Stanford University School of Medicine researchers have identified one pathway in this important process in mice that, if disrupted, causes a lupuslike autoimmune disease. view more (2009-10-19)

Biofuel production could undercut efforts to shrink Gulf 'Dead Zone'
Scientists in Pennsylvania report that boosting production of crops used to make biofuels could make a difficult task to shrink a vast, oxygen-depleted "dead zone" in the Gulf of Mexico more difficult. view more (2009-09-17)
Oxygen-saturated blood reduces levels of damaged heart tissue following a heart attack
Results of a clinical trial published today in Circulation: Cardiovascular Interventions demonstrate that an infusion of blood that is "supersaturated" with oxygen (SS02) can reduce the amount of damaged heart muscle immediately following a life-threatening heart attack. view more (2009-09-16)
Biologists discover 'death stench' is a universal ancient warning signal

Golf course putting greens show their age
Just like the rest of us, golf courses show their age-especially on putting greens, which experience more foot traffic than anywhere else on golf courses. Putting greens, which comprise only about 1.6% of the total area on most courses, require more intensive management than any other part of the course. view more (2009-09-04)
Ocean-drilling expedition cites new evidence related to origin and evolution of seismogenic faults
New research about what triggers earthquakes, authored by Michael Strasser of Bremen University, Germany, with colleagues from the USA, Japan, China, France, and Germany, will appear in the Aug. 16 2009 issue of Nature Geoscience. view more (2009-08-18)
Listening to rocks helps researchers better understand earthquakes
When Apollo punished King Midas by giving him donkey ears, only the king and his barber knew. Unable to keep a secret, the barber dug a hole, whispered into it, "King Midas has donkey ears," and filled the hole. But plants sprouted from the hole, and with each passing breeze, shared the king's secret. view more (2009-08-18)
Parasite causes zombie ants to die in an ideal spot
A study in the September issue of The American Naturalist describes new details about a fungal parasite that coerces ants into dying in just the right spot-one that is ideal for the fungus to grow and reproduce. view more (2009-08-12)
Physicists make crystal/liquid interface visible for first time
"Imagine you're a water molecule in a glass of ice water, and you're floating right on the boundary of the ice and the water," proposes Emory University physicist Eric Weeks. "So how do you know if you're a solid or a liquid?" view more (2009-08-11)
