Federal financing of science research, which has risen quickly since the Obama administration came to power, could fall back to pre-Obama levels if the incoming Republican leadership in the House of Representatives follows through on its list of campaign promises.

In the Republican platform, Pledge to America, the party vows to cut discretionary nonmilitary spending to 2008 levels. Under that plan, research and development at nonmilitary agencies  including those that sponsor science and health research  would fall 12.3 percent, to $57.8 billion, from the Mr. Obama’s request of $65.9 billion for fiscal year 2011.

An analysis by the American Association for the Advancement of Science looked at what would happen if all of the agencies were cut to the 2008 amounts. The National Institutes of Health would lose $2.9 billion, or 9 percent, of its research money. The National Science Foundation would lose more than $1 billion, or almost 19 percent, of its budget, and the National Oceanic and Atmospheric Administration would lose $324 million, or 34 percent.
