The National Academy of Sciences (NAS) is a United States nonprofit, non-governmental organization. NAS is part of the National Academies of Sciences, Engineering, and Medicine, along with the National Academy of Engineering (NAE) and the National Academy of Medicine (NAM). As a national academy, new members of the organization are elected annually by current members, based on their distinguished and continuing achievements in original research. Election to the National Academy is one of the highest honors in the scientific field. Members of the National Academy of Sciences serve pro bono as "advisers to the nation" on science, engineering, and medicine. The group holds a congressional charter under Title 36 of the United States Code. Founded in 1863 as a result of an Act of Congress that was approved by Abraham Lincoln, the NAS is charged with "providing independent, objective advice to the nation on matters related to science and technology. ... to provide scientific advice to the government 'whenever called upon' by any government department." The Academy receives no compensation from the government for its services. Overview , the National Academy of Sciences includes 2,493 NAS members and 491 international members. It employed about 1,100 staff in 2005. Some 190 members have won a Nobel Prize. By its own admission in 1989, the addition of women to the Academy "continues at a dismal trickle", at which time there were 1,516 male members and 57 female members. The National Academy of Sciences is one of the 135 member organizations of the International Science Council (ISC). Although there is no formal relationship with state and local academies of science, there often is informal dialogue. The National Academy is governed by a 17-member Council, made up of five officers (president, vice president, home secretary, international secretary, and treasurer) and 12 Councilors, all of whom are elected from among the Academy membership. Agencies of the United States government fund about 85 percent of the Academy's activities. Further funding comes from state governments, private foundations, and industrial organizations. The Council has the ability ad-hoc to delegate certain tasks to committees. For example, the Committee on Animal Nutrition has produced a series of Nutrient requirements of domestic animals reports since at least 1944, each one being initiated by a different sub-committee of experts in the field for example on dairy cattle. The National Academy of Sciences meets annually in Washington, D.C., which is documented in the
