They increased crop production in some areas while threatening local food security in other areas. The study, published in the Procedure of the National Academy of Sciences Led by the University of […]
Pyrolyzed ash turned into graphene to improve concrete and other compounds – ScienceDaily
Pyrolyzed plastic ash is worthless, but it may not last for long. Rice University scientists have turned their attention to the Joule heating of the material, a by-product of plastic recycling processes. A strong burst of energy makes it flash in graphs. The technique of the laboratory of the rechemist James Tour creates turbostratic graphene […]
Jellyfish create a "virtual wall" to improve performance – ScienceDaily
New research from the University of South Florida has uncovered one of the reasons jellyfish became known as "the world's most efficient swimmer." Brad Gemmell, associate professor of integrative biology, found that jellyfish produce two vortex rings, which are donut-shaped bodies of liquid beneath their translucent bodies that rotate in opposite directions. They appear as […]
Study shows waves, rainfall important parts of erosion process, providing new opportunity to improve forecasts — ScienceDaily
Scripps Institution of Oceanography at UC San Diego researchers have uncovered how rain and waves act on different parts of coastal cliffs. Following three years of cliff surveys in and near the coastal city of Del Mar, Calif., they determined that wave impacts directly affect the base, and rain mostly impacts the upper region of […]
