NASA sponsored scientists have discovered by knowing the salt content of the ocean’s surface, they may be able to improve the ability to predict El Nino events. Scientists, studying the western Pacific Ocean, find regional changes in the saltiness of surface ocean water correspond to changes in upper ocean heat content in the months preceding an El Nino event. Knowing the distribution of surface salinity may help predict events.
Salinity and temperature combine to dictate the ocean’s dens
White tea extract reveals anti-cancer, anti-aging properties
Scientists at University Hospitals of Cleveland and Case Western Reserve University have proven that ingredients in white tea are effective in boosting the immune function of skin cells and protecting them against the damaging effects of the sun. The discovery that white tea extract protects the skin from oxidative stress and immune cell damage adds another important element in the battle against skin cancer.

Data gathered by Penn State engineers in a volunteer effort at the World Trade Center tragedy, suggests that simple, inexpensive microphones dropped into the rubble of a collapsed building may be able to aid search and rescue teams despite ground level noise.
Dr. Thomas B. Gabrielson, associate professor of acoustics and senior research associate at Penn State’s Applied Research Laboratory, says, “In conventional survivor searches, noise generating activities at the surface must be stopped
Scientists have long touted carbon nanotubes as a futuristic means of delivering drugs, fortifying brittle materials and conducting current in miniaturized circuits. But attempts to introduce actual nanotubes into these roles have often been stopped in their tracks by the slender filaments stubborn and unhelpful tendency to clump together in solution.
Now scientists at the University of Pennsylvania have found that a readily available chemical, a surfactant called sodium dodecylbenzen
When 29-year-old Eric Lange suddenly experienced several hours of mental confusion last July, physicians at Cedars-Sinai Medical Center naturally ordered brain scans and carotid artery studies in their first search for a cause. With the initial exams turning out OK, Eric’s neurologist pursued other clues and ended up finding a heart defect called a patent foramen ovale, or PFO. A blood clot was believed to have slipped through the defect and out of the normal route of circulation that would
As Rebecca Brown kayaked down the Nolichucky River in North Carolina one summer, she followed a path similar to many of her own study subjects. Seeds and other propagules often float downstream before settling along riverbanks. Rampant with change, these areas offer a nutrient-rich location for new plants, yet pose the danger of sweeping vegetation away in a flood. It is this high volatility that makes the area resource rich and perfect for invasive and native plants to put down their roots. In a stu
