Microbial 'Cheaters' Help Scientists ID 'Social' Genes
February 13, 2008
The first genome-wide search for genes governing social behavior has found that even the simplest social creatures--the amoebae Dictyostelium discoideum--have more than 100 genes that help regulate their cooperative behavior. This study marks one of the first large-scale attempts to combine evolutionary biology with genomics in a systematic search for genes tied to social behavior.
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.
