         The Research and Related Activities appropriation enables the United States to provide leadership and promote progress across
            the expanding frontiers of scientific and engineering research and education.
         
         The major research program activities of NSF are:
         Biological Sciences.âThis activity supports understanding how complex living systems function and interact with each other and with non-living
            systems, which has direct impact on issues of national importance related to the economy, food, human welfare, and the environment.
            Research in this activity promotes scientific progress through support of research that crosses scales, from molecules to
            cells through organisms to ecosystems. This activity's investment portfolio includes projects on understanding the fundamental
            characteristics of biological energy systems, the changing dynamics of the biosphere, and infrastructure and research resources
            such as databases, research centers, and observatories, and efforts to broaden participation and develop the next generation
            of biological researchers.
         
         Computer and Information Science and Engineering.âThis activity supports investigator initiated research in all areas of computer and information science and engineering,
            helps develop and maintain cutting-edge national computational and information infrastructure for research and education generally,
            and contributes to the education and training of the next generation of computer and computational engineers.
         
         Engineering.âResearch supported by this activity aims to increase U.S. engineering capability and strength, and focus that capability
            and strength on areas that are relevant to national problems and long-term needs. This activity also includes small business
            innovation research.
         
         Geosciences.âThis activity supports research and associated infrastructure to advance knowledge of the properties and dynamics of the
            planet on which we live. Research includes understanding the causes and implications of earth system dynamics, as well as
            disruptive processes such as earthquakes and storms.
         
         Mathematical and Physical Sciences.âResearch in this activity is directed at increasing understanding of natural laws and phenomena across the astronomical
            sciences, chemistry, materials sciences, mathematical sciences, and physics. Research support is available in multiple modalities
            ranging from multi-user facilities and mid-scale instrumentation to individual investigator awards, from sites for undergraduate
            research experiences to early career faculty development and collaborative and international efforts.
         
         Social, Behavioral, and Economic Sciences.âThis activity supports research, education, and infrastructure in the social, behavioral, cognitive, and economic sciences
            and funds the collection and dissemination of statistics on the science and engineering enterprise.
         
         Office of International Science and Engineering.âThis activity serves as the focal point of international activities at NSF. In addition to strategic funding and co-funding
            that targets catalytic partnerships and workforce-building international research opportunities, OISE advances NSF's global
            science leadership through extensive interactions with U.S. and global counterpart agencies and organizations.
         
         Office of Polar Programs.âThis activity supports Arctic and Antarctic research and operational science support and other related activities for United
            States polar research programs, including the funding to reimburse Federal agencies for logistical and other related activities
            supported by the United States Antarctic Program.
         
         Integrative Activities.âThis activity supports emerging cross disciplinary research efforts and major research instrumentation. This activity also
            provides support for the Science and Technology Policy Institute. The Experimental Program to Stimulate Competitive Research
            broadens participation of States and regions in science and engineering by helping institutions expand their research capacity
            and competitiveness.
         
         The United States Arctic Research Commission (USARC) is an independent agency, funded through NSF's appropriations. USARC promotes Arctic research and recommends national Arctic
            research policies to guide Federal agencies in developing and implementing their research programs in the Arctic region.

         The Education and Human Resources (EHR) appropriation funds and manages a comprehensive set of programs that further NSF's
            goals of ensuring a diverse, globally competitive U.S. science, technology, engineering, and mathematics (STEM) workforce,
            as well as a scientifically literate population. To advance those goals, EHR collaborates with other NSF research units, federal
            agencies, and promotes public-private partnerships. EHR supports research on STEM teaching and learning to provide the evidence
            base for improvements in education at all levels in the STEM disciplines. Supporting development and effective implementation
            of new learning technologies is also a priority. EHR's pre-K-12 education-research programs, for example, develop and test
            new instruction materials for students and teachers, which incorporate the latest advances in teaching, learning, and education
            technologies. STEM teacher-education opportunities occur throughout the full continuum, from pre-service and in-service, through
            life-long learning. Research programs at the undergraduate level improve curricula, strengthen laboratory courses, enhance
            faculty effectiveness and lead education reforms in STEM disciplines. Advanced technological education programs strengthen
            student preparation for the high-technology workforce. Support of graduate-level STEM education primarily includes fellowships
            and traineeships to sustain U.S. leadership in global science and technology. All EHR programs aim to broaden participation
            of groups underrepresented in STEM fields by, for example, improving infrastructure and academic programs at minority-serving
            institutions.  EHR activities also include programs supported by H-1B non-immigrant visa fees, which provide undergraduate
            and graduate scholarships in STEM disciplines, improve educational opportunities for students, and provide research opportunities
            for STEM teachers and students.

         This account consists of contributions from foreign governments, organizations, and individuals to fund various cooperative
            efforts in science, research, and education. These efforts include major international projects, such as operation of the
            Gemini telescopes, and the NSF ocean discovery program. Other smaller activities supported include cooperative research, joint
            seminars, exchange of senior scientists, short-term research development visits, international conferences, and support for
            certain special functions of NSF and the National Science Board. These funds are not otherwise available.
