A study led by a Duke University scientist suggests that the current emphasis on controlling upstream nitrogen pollution fails to adequately address the impacts on water quality of another potential contaminant, phosphorus. Thus, according to the scientists, current strategies used by environmental managers to control excessive nutrients in coastal wetlands may not achieve their intended goals.
The finding was published in a report in the Friday, Jan. 24, 2003, issue of the journal Science by Pallaoor Venkatesh Sundareshwar, a research associate and instructor at the Duke University Wetland Center in the Nicholas School of the Environment and Earth Sciences and co-authors James Morris and Brandon Fornwalt from the University of South Carolina at Columbia, and Eric Koepfler from Coastal Carolina University in Conway, S.C. The study was funded by the National Science Foundation and the National Oceanic and Atmospheric Administration.
Sundareshwar and his co-authors worked in a pristine wetland at the University of South Carolinas Baruch Marine Field Laboratory, near Georgetown, where organisms natural interactions could be studied in the absence of human-caused pollution.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
