A U.S. scientist urges that equal attention be given to phosphorus and nitrogen produced by human activity that are degrading water quality and aquatic life. University of North Carolina at Chapel Hill Professor Hans Paerl notes the priority has historically been given to controlling phosphorus. But Paerl argues nitrogen imbalance is equally damaging and a dual nutrient strategy is necessary to manage the problem effectively. The combination of human population growth, urbanization and...

New study argues need for dual nutrient strategy to improve aquatic ecosystemsExcess phosphorus and nitrogen produced by human activities on neighboring land is making its way into our coastal waters and degrading both water quality and aquatic life. Although historically the priority has been to control phosphorus, Professor Hans Paerl, from the University of North Carolina in the US, argues that nitrogen imbalance is equally damaging. He adds that a dual nutrient strategy "“ tackling...

Presidential Executive Order Makes Restoration of Bay a National Priority HARRISBURG, Pa., May 14 /PRNewswire-USNewswire/ -- Environmental Protection Secretary John Hanger today outlined how new, clearly-defined and attainable nutrient reduction goals for the Chesapeake Bay and a presidential order calling for increased federal participation in the cleanup will accelerate recovery of the bay while greatly improving the health of Pennsylvania's rivers and streams. Hanger represented...

U.S. government oceanographers say they've determined plankton carbon particles in the Southern Ocean never reached the deep ocean. Jim Bishop and Todd Wood of the U.S. Department of Energy's Lawrence Berkeley National Laboratory studied the fate of carbon particles originating in plankton blooms using data deep-diving Carbon Explorer floats collected around the clock for more than a year. The discovery that most of the carbon never reaches the deep ocean deals a blow to the simplest version...

The discovery of a soccer-ball-shaped molecule made of 60 carbon atoms was a minor revolution in chemistry: Fullerenes are spherical, highly symmetrical molecules made of carbon atoms, and are the third form of carbon after diamond and graphite. However, the C60 "soccer ball" is not the only fullerene by far. Among its less stable relations is the C80 fullerene. There are seven different possible structural forms that have 80 carbon atoms in a symmetrical, spherical arrangement. Among the...

British scientists say the Earth's crops and drinking water could be adversely affected if predicted climate changes occur in rainfall patterns. Scientists from North Wyke Research say they have determined, for the first time, how the rate at which dried soil is rewetted affects the amount of phosphorus lost from the soil into surface water and subsequently into the surrounding environment. Martin Blackwell, one of the project leaders, said the study's preliminary results show the changing...

Crop growth, drinking water and recreational water sports could all be adversely affected if predicted changes in rainfall patterns over the coming years prove true, according to research published this month in Biology and Fertility of Soils. Scientists from Biotechnology and Biological Sciences Research Council (BBSRC)-funded North Wyke Research have found for the first time that the rate at which a dried soil is rewetted impacts on the amount of phosphorus lost from the soil into surface...

Scientists have developed a new approach for surveying phosphorylation, a process that is regulated by critical cell signaling pathways and regulates several key cellular signaling events. The research, published by Cell Press in the April 10th issue of the journal Molecular Cell, describes the regulation of a previously uncharacterized protein and demonstrates that it plays an important role in cancer cell invasion.Many cancers, including melanoma, are associated with mutations in the gene...

Polluted water from Chicago has helped create a dead zone in the Gulf of Mexico, where excess algae suffocates marine life, says a U.S. Geological Survey study. Chicago was named the top offender in the study of the causes of nitrogen and phosphorus pollution in the 8,000 square-foot dead zone, Chi-TownDailyNews.org reported Friday. The study released Thursday examined sources for 150 watersheds in the Mississippi River Basin. Chicago's Metropolitan Water Reclamation District, or MWRD, ranked...

University of Hawaii at Manoa researchers involved in novel strategy Phytoplankton comprise the forests of the sea, and are responsible for providing nearly half of the oxygen that sustains life on Earth including our own. However, unlike their counterparts on land, the marine plants are nearly exclusively microscopic in size, and mostly out of human sight. Consequently, we are still in a very early stage of understanding even the most basic aspects of phytoplankton biology and ecology. In a...

In chemistry, a phosphate is a polyatomic ion or radical consisting of one phosphorus atom and four oxygen. In the ionic form, it carries a -3 formal charge, and is denoted PO43-. In a biochemical setting, a free phosphate ion in solution is called inorganic phosphate, to distinguish it from phosphates bound in the form of ATP, or perhaps in DNA or RNA. Inorganic phosphate is generally denoted Pi. Inorganic phosphate can be formed by the reactions of ATP, or ADP, with the formation of the...
