Last year, Kenya lost 278 elephants to poachers, as compared to 177 in 2010. On the continent of Africa as whole, elephants have declined from an estimated 700,000 in 1990 to 360,000 today due to the demands of the ivory trade. Spend some time with University of Notre Dame researchers Elizabeth A...
As soon as women quit hormone therapy, their rates of new breast cancer decline, supporting the hypothesis that stopping hormones can lead to tumor regression, according to a report e-published in Cancer Epidemiology, Biomarkers, & Prevention.
A weak tropical low pressure area known as System 92S, and locally called Irina caused flooding over northern Madagascar less than two weeks after deadly flooding by Tropical Cyclone Giovanna in the south and central part of the island nation. NASA's TRMM satellite measured System 92S's rainfall ove...
A new discovery involving two Simon Fraser University scientists could lead to a little known and benign bacterium becoming a vital new tool in the development of a vaccine against human immunodeficiency virus (HIV).
Slowing or preventing the development of Alzheimer's disease, a fatal brain condition expected to hit one in 85 people globally by 2050, may be as simple as ensuring a brain protein's sugar levels are maintained. That's the conclusion seven researchers, including David Vocadlo, a Simon Fraser Uni...
In the United States alone, approximately 6 million people suffer from an irregular heartbeat called atrial fibrillation (AF), and since the incidence increases with age, it is predicted that 15.9 million Americans will be affected by 2050. The most devastating side effect of AF is stroke, but a new...
Scientists from the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawaii – Manoa (UHM) and colleagues recently discovered that land-based plant material and coastal macroalgae indirectly support the increased abundances of bottom fish in submarine canyons, like...
A chemically altered osteoporosis drug may be useful in fighting malaria, researchers report in a new study. Unlike similar compounds tested against other parasitic protozoa, the drug readily crosses into the red blood cells of malaria-infected mice and kills the malaria parasite. The drug works at ...
The frigid McMurdo Dry Valleys in Antarctica are a cold, polar desert, yet the sandy soils there are frequently dotted with moist patches in the spring despite a lack of snowmelt and no possibility of rain. A new study, led by an Oregon State University geologist, has found that that the salty so...
NASA satellites have been watching the low pressure area called System 92S for days, and infrared imagery from NASA's Aqua satellite showed cloud temperatures were cooling, indicating the storm was getting more organized after it moved over northern Madagascar. Now it may be headed for landfall in M...
A long-standing controversy regarding the semiconductor gallium manganese arsenide, one of the most promising materials for spintronic technology, looks to have been resolved. Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab)in collaboration with s...
Humans are frequently blamed for deforestation and the destruction of environments, yet there are also examples of peoples and cultures around the world that have learned to manage and conserve the precious resources around them. The Yanesha of the upper Peruvian Amazon and the Tibetans of the Himal...
