a leaf of eriachne ciliata grass Two groups, or clades, of grasses that once had a common ancestry diverged, ultimately leaving the PACMAD clade more predisposed to evolve a more efficient "C4" means of photosynthesis when carbon dioxide is restricted than grasses in the BEP clade. In a new study in the Proceedings of the National Academy of Sciences, a Brown University-led team pinpoints the anatomical differences between the clades that led to the PACMAD's tendency toward C4.

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.
