News From the Field
Metabolic Reactions: Less is More in Single-celled Organisms

December 5, 2008

Adilson Motter A Northwestern University study of four single-celled organisms had some surprising results. The organisms, which differed in size and complexity of each organism's genome, used the same number of biochemical reactions when optimizing growth. And, contrary to what you might expect, each, to efficiently perform metabolic tasks such as growing fast or converting sugars to ethanol, tended to use only a small fraction of the biochemical reactions available to them in the metabolic network. Full Story

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2014, its budget is $7.2 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 50,000 competitive requests for funding, and makes about 11,500 new funding awards. NSF also awards about $593 million in professional and service contracts yearly.
