Riparian buffers -- the vegetated border along streams and wetlands -- may decrease the amount of nitrogen that enters water bodies and the width of these buffers may have a positive relation to a decrease in nitrogen levels.

Scientists have identified a new technique for cleansing contaminated water and potentially purifying hydrogen for use in fuel cells, thanks to the discovery of a innovative type of porous material.

Researchers have discovered through genetic analyses a metabolic pathway in bacteria comprised of just three genes, all known to be players in metabolism. This pathway was previously shown to be involved in synthesizing modified membrane lipids but the new data indicates it also has a major role in cell division. This is the first identification of a pathway responsible for regulating bacterial cell size.
