Researchers at the University of Leeds have uncovered new clues to the origins of life on Earth. The team found that a compound known as pyrophosphite may have been an important energy source for primitive lifeforms. There are several conflicting theories of how life on Earth emerged from inanimate matter billions of years ago "“ a process known as abiogenesis. "It's a chicken and egg question," said Dr Terry Kee of the University of Leeds, who led the research. "Scientists are in...

The evolution of complex life forms may have gotten a jump start billions of years ago, when geologic events operating over millions of years caused large quantities of phosphorus to wash into the oceans. According to this model, proposed in a new paper by Dominic Papineau of the Carnegie Institution for Science, the higher levels of phosphorus would have caused vast algal blooms, pumping extra oxygen into the environment which allowed larger, more complex types of organisms to thrive....

Algae--already being eyed for biofuel production--could be put to use right away to remove nitrogen and phosphorus in livestock manure runoff, according to an Agricultural Research Service (ARS) scientist. That could give resource managers a new eco-friendly option for reducing the level of agricultural pollutants that contaminate water quality in the Chesapeake Bay. Microbiologist Walter Mulbry works at the ARS Environmental Management and Byproduct Utilization Research Unit in Beltsville,...

NSF-supported ecologist James Elser is internationally recognized as an expert on phosphorus in biology and ecology, and his research could help to change society's views on phosphorus use and conservation Earth Day is celebrated by more than 1 billion people worldwide, but before 1969, it was a nascent idea seeking fertile ground (so to speak). This makes one wonder how a scientific concept, for example, conservation of a chemical element, can be transformed into a broader movement. The...

New research in the FASEB Journal shows that high levels of phosphate in sodas and processed foods accelerate the aging process in mice and contribute to age-associated complications such as chronic kidney disease Here's another reason to kick the soda habit. New research published online in the FASEB Journal (http://www.fasebj.org) shows that high levels of phosphates may add more "pop" to sodas and processed foods than once thought. That's because researchers found that the high levels of...

Balancing phosphorus levels in crop lands is a key factor that is often overlooked in discussions of global food security, according to a paper published in the International Journal of Agricultural Resources, Governance and Ecology. Current global issues include carbon footprints, water resources and climate change. However, the non-renewable element phosphorus for plant growth is often overlooked in the global context. Biologist John Lott of McMaster University, in Hamilton, Ontario,...

Research by astrobiologist William Bains suggests that if life has evolved on the frozen surface of Saturn's moon, Titan, it would be strange, smelly and explosive compared to life on Earth. Dr Bains will present his work at the National Astronomy Meeting in Glasgow on Tuesday April 13th. "Hollywood would have problems with these aliens" says Dr. Bains. "Beam one onto the Starship Enterprise and it would boil and then burst into flames, and the fumes would kill everyone in range. Even a tiny...

New research at Brown University explains how a key enzyme, PP1, functions in protein-protein interactions. In a paper published online in Nature Structural & Molecular Biology, Wolfgang Peti has described how PP1 "chooses" proteins. The finding is important, because erroneous PP1 regulation can cause numerous diseases, including cancer, diabetes and Parkinson's. Protein phosphorylation is a process by which proteins are flipped from one activation state to another. It is a crucial...

A study by Agricultural Research Service (ARS) scientists shows that sugarcane can tolerate flooded conditions for up to two weeks. That's good news for growers who are using best management practices for controlling phosphorous runoff into the Everglades. Phosphorous stays attached to the soil for a long time even with the moderate rates of phosphorous fertilizer applied to sugarcane in Florida. If growers immediately drain their flooded fields after heavy rains have stirred up the soil,...

WEST PALM BEACH, Fla., March 5 /PRNewswire/ -- The Everglades Agricultural Area (EAA) receives praise for its proven success in cleaning water south of Lake Okeechobee by two top state environmental agencies in their annual restoration report. The 2010 South Florida Environmental Report, published by the Florida Department of Environmental Protection and the South Florida Water Management District, reveals the EAA achieved a 68 percent reduction in phosphorus loads in 2009 and an overall...

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...
