Advanced computing capabilities are used to tackle a rapidly growing range of challenging science and engineering problems, many of which are compute- and data-intensive as well. Demand for advanced computing has been growing for all types and capabilities of systems, from large numbers of single commodity nodes to jobs requiring thousands of cores; for systems with fast interconnects; for systems with excellent data handling and management; and for an increasingly diverse set of applications that includes data analytics as well as modeling and simulation. Since the advent of its supercomputing centers, the National Science Foundation (NSF) has provided its researchers with state-of-the-art computing systems. The growth of new models of computing, including cloud computing and publically available by privately held data repositories, opens up new possibilities for NSF. In order to better understand the expanding and diverse requirements of the science and engineering community and the importance of a new broader range of advanced computing infrastructure, the NSF requested that the National Research Council carry out a study examining anticipated priorities and associated tradeoffs for advanced computing. This interim report identifies key issues and discusses potential options. Future Directions for NSF Advanced Computing Infrastructure to Support U.S. Science and Engineering in 2017-2020 examines priorities and associated tradeoffs for advanced computing in support of NSF-sponsored science and engineering research. This report is an initial compilation of issues to be considered as future NSF strategy, budgets, and programs for advanced computing are developed. Included in the report are questions on which the authoring committee invites comment. We invite your feedback on this report, and more generally, your comments on the future of advanced computing at NSF.
As the availability of high-throughput data-collection technologies, such as information-sensing mobile devices, remote sensing, internet log records, and wireless sensor networks has grown, science, engineering, and business have rapidly transitioned from striving to develop information from scant data to a situation in which the challenge is now that the amount of information exceeds a human's ability to examine, let alone absorb, it. Data sets are increasingly complex, and this potentially increases the problems associated with such concerns as missing information and other quality concerns, data heterogeneity, and differing data formats. The nation's ability to make use of data depends heavily on the availability of a workforce that is properly trained and ready to tackle high-need areas. Training students to be capable in exploiting big data requires experience with statistical analysis, machine learning, and computational infrastructure that permits the real problems associated with massive data to be revealed and, ultimately, addressed. Analysis of big data requires cross-disciplinary skills, including the ability to make modeling decisions while balancing trade-offs between optimization and approximation, all while being attentive to useful metrics and system robustness. To develop those skills in students, it is important to identify whom to teach, that is, the educational background, experience, and characteristics of a prospective data-science student; what to teach, that is, the technical and practical content that should be taught to the student; and how to teach, that is, the structure and organization of a data-science program. Training Students to Extract Value from Big Data summarizes a workshop convened in April 2014 by the National Research Council's Committee on Applied and Theoretical Statistics to explore how best to train students to use big data. The workshop explored the need for training and curricula and coursework that should be included. One impetus for the workshop was the current fragmented view of what is meant by analysis of big data, data analytics, or data science. New graduate programs are introduced regularly, and they have their own notions of what is meant by those terms and, most important, of what students need to know to be proficient in data-intensive work. This report provides a variety of perspectives about those elements and about their integration into courses and curricula.
"Summary of a Workshop on Mississippi River Water Quality Science and Interstate Collaboration summarizes presentations and discussions of Mississippi River and basin water quality management, monitoring, and evaluation programs that took place at a workshop that was held in St. Louis on November 18-19, 2013. The workshop examined a wide array of challenges and progress in water quality monitoring and evaluation in states along the Mississippi River corridor, and provided a forum for experts from U.S. federal agencies, the Mississippi River states, nongovernmental organizations, and the private sector to share and compare monitoring and evaluation experiences from their respective organizations."--Publisher's description.
"The United States has been a generous sponsor of global health programs for the past 25 years or more. This investment has contributed to meaningful changes, especially for women and children, who suffer the brunt of the world's disease and disability. Development experts have long debated the relative merits of vertical health programming, targeted to a specific service or patient group, and horizontal programming, supporting more comprehensive care. The U.S. government has invested heavily in vertical programs, most notably through the President's Emergency Plan for AIDS Relief (PEPFAR), its flagship initiative for HIV and AIDS. PEPFAR and programs like it have met with good success. Protecting these successes and continuing progress in the future depends on the judicious integration of vertical programs with local health systems. A strong health system is the best insurance developing countries can have against a disease burden that is shifting rapidly and in ways that history has not prepared us for. Reaching the poor with development assistance is an increasingly complicated task. The majority of the roughly 1 billion people living in dire poverty are in middle-income countries, where foreign assistance is not necessarily needed or welcome. Many of the rest live in fragile states, where political volatility and weak infrastructure make it difficult to use aid effectively. The poorest people in the world are also the sickest; they are most exposed to disease vectors and infection. Nevertheless, they are less likely to access health services. Improving their lot means removing the systemic barriers that keep the most vulnerable people from gaining such access. Investing in Global Health Systems discusses the past and future of global health. First, the report gives context by laying out broad trends in global health. Next, it discusses the timeliness of American investment in health systems abroad and explains how functional health systems support health, encourage prosperity, and advance global security. Lastly, it lays out, in broad terms, an effective donor strategy for health, suggesting directions for both the manner and substance of foreign aid given. The challenge of the future of aid programming is to sustain the successes of the past 25 years, while reducing dependence on foreign aid. Investing in Global Health Systems aims to help government decision makers assess the rapidly changing social and economic situation in developing countries and its implications for effective development assistance. This report explains how health systems improvements can lead to better health, reduce poverty, and make donor investment in health sustainable"--
"For over a century, field stations have been important entryways for scientists to study and make important discoveries about the natural world. They are centers of research, conservation, education, and public outreach, often embedded in natural environments that range from remote to densely populated urban locations. Because they lack traditional university departmental boundaries, researchers at field stations have the opportunity to converge their science disciplines in ways that can change careers and entire fields of inquiry. Field stations provide physical space for immersive research, hands-on learning, and new collaborations that are otherwise hard to achieve in the everyday bustle of research and teaching lives on campus. But the separation from university campuses that allows creativity to flourish also creates challenges. Sometimes, field stations are viewed as remote outposts and are overlooked because they tend to be away from population centers and their home institutions. This view is exacerbated by the lack of empirical evidence that can be used to demonstrate their value to science and society. Enhancing the Value and Sustainability of Field Stations and Marine Laboratories in the 21st Century summarizes field stations' value to science, education, and outreach and evaluates their contributions to research, innovation, and education. This report suggests strategies to meet future research, education, outreach, infrastructure, funding, and logistical needs of field stations. Today's technologies - such as streaming data, remote sensing, robot-driven monitoring, automated DNA sequencing, and nanoparticle environmental sensors - provide means for field stations to retain their special connection to nature and still interact with the rest of the world in ways that can fuel breakthroughs in the environmental, physical, natural, and social sciences. The intellectual and natural capital of today's field stations present a solid platform, but many need enhancements of infrastructure and dynamic leadership if they are to meet the challenges of the complex problems facing the world. This report focuses on the capability of field stations to address societal needs today and in the future."--
The Arctic has been undergoing significant changes in recent years. Average temperatures are rising twice as fast as they are elsewhere in the world. The extent and thickness of sea ice is rapidly declining. Such changes may have an impact on atmospheric conditions outside the region. Several hypotheses for how Arctic warming may be influencing mid-latitude weather patterns have been proposed recently. For example, Arctic warming could lead to a weakened jet stream resulting in more persistent weather patterns in the mid-latitudes. Or Arctic sea ice loss could lead to an increase of snow on high-latitude land, which in turn impacts the jet stream resulting in cold Eurasian and North American winters. These and other potential connections between a warming Arctic and mid-latitude weather are the subject of active research. Linkages Between Arctic Warming and Mid-Latitude Weather Patterns is the summary of a workshop convened in September 2013 by the National Research Council to review our current understanding and to discuss research needed to better understand proposed linkages. A diverse array of experts examined linkages between a warming Arctic and mid-latitude weather patterns. The workshop included presentations from leading researchers representing a range of views on this topic. The workshop was organized to allow participants to take a global perspective and consider the influence of the Arctic in the context of forcing from other components of the climate system, such as changes in the tropics, ocean circulation, and mid-latitude sea surface temperature. This report discusses our current understanding of the mechanisms that link declines in Arctic sea ice cover, loss of high-latitude snow cover, changes in Arctic-region energy fluxes, atmospheric circulation patterns, and the occurrence of extreme weather events; possible implications of more severe loss of summer Arctic sea ice upon weather patterns at lower latitudes; major gaps in our understanding, and observational and/or modeling efforts that are needed to fill those gaps; and current opportunities and limitations for using Arctic sea ice predictions to assess the risk of temperature/precipitation anomalies and extreme weather events over northern continents.
"On November 7-8, 2013, the Institute of Medicine's Roundtable on Environmental Health Sciences, Research, and Medicine held a workshop to discuss approaches related to identifying and reducing potential environmental public health risks to new and existing industrial chemicals present in society. Industrial chemicals include chemicals used in industrial processes or commercial products, not including those found in food, pesticides, or pharmaceuticals. Identifying and Reducing Environmental Health Risks of Chemicals in Our Society is a summary and synthesis of the presentations and discussions that took place during the two days of the workshop. The workshop examined successes and areas for improvement within current regulatory programs for assessing industrial chemical safety, frameworks for chemical prioritization to inform targeted testing and risk management strategies, concepts of sustainability and green chemistry that support the design and use of safer alternatives, and efforts to reduce the risk of chemicals in our society."--Publisher's description.

The California Institute for Regenerative Medicine (CIRM) was created in 2005 by The California Stem Cell Research and Cures Act (Proposition 71) to distribute $3 billion in state funds for stem cell research. The passage of Proposition 71 by the voters of California occurred at a time when federal funding for research involving human embryonic stem cells was uncertain, given the ethical questions raised by such research. During its initial period of operations, CIRM has successfully and thoughtfully provided more than $1.3 billion in awards to 59 California institutions, consistent with its stated mission. As it transitions to a broadened portfolio of grants to stimulate progress toward its translational goals, the Institute should obtain cohesive, longitudinal, and integrated advice; restructure its grant application review process; and enhance industry epresentation in aspects of its operations. CIRM's unique governance structure, while seful in its initial stages, might diminish its effectiveness moving forward. The California Institute for Regenerative Medicine: Science, Governance, and the Pursuit of Cures recommends specific steps to enhance CIRM's organization and management, as well as its scientific policies and processes, as it transitions to the critical next stages of its research and development program.
"According to recent reports, the United States currently accounts for less than one-third of global research and development spending, and it is projected that this fraction will decline to 18% by 2050. These statistics, compounded by the recognition that the United States no longer maintains technological superiority across all research fields, highlight the need for the U.S. research community to stay abreast of emerging science and technology (S & T) around the world, to leverage others' investments, and to seek out collaborations in areas where researchers need to remain at the leading edge. ... This report considers DoD strategies in the three Services for leveraging global S & T and implementation and coordination of these strategies across DoD. The report explores models for global S & T engagement utilized by other domestic and foreign organizations. Strategic Engagement in Global S & T assesses how the ongoing globalization of S & T may impact research funding and priorities and workforce needs, as well as issues of building and maintaining trusted relationships and avoiding technology surprises"--Publisher's description.
Potential health effects from chemicals that disrupt endocrine function pose an environmental health concern because of their ability to interfere with normal hormone function in human and wildlife populations. The endocrine system regulates biological processes throughout the body and is sensitive to small changes in hormone concentrations. Endocrine-disruptor research has focused primarily on chemicals that affect three hormone pathways that play important roles in reproduction and development - the estrogen, androgen, and thyroid hormone pathways. Some of this research has identified dose-response relationships that have nonmonotonic curves. Nonmonotonic dose-response curves (NMDRs) are of concern because they do not follow the usual assumption made in toxicology that as dose decreases the response also decreases. The existence of NMDRs has been a controversial topic for decades, and there has been considerable debate about their implications for how chemicals are tested and for how risks from such chemicals are assessed. Toxicity tests are designed to identify hazards and to characterize dose-response relationships, so tests are aimed at finding a (high) dose that elicits a response, and dose-response is explored by testing lower doses spaced to identify statistically a no- or lowest-observed-adverse-effect level. The concern for NMDRs is that such studies, as currently designed, might not detect the inflection of the dose-response curve if only a few doses are tested or if the change in inflection occurs below the range of doses tested. Another concern is that some NMDRs are found for biological effects that are not usually evaluated in toxicity tests. If current testing strategies are inadequate to account for NMDRs, changes to risk assessment practices might be necessary. To help address these issues, the U.S. Environmental Protection Agency (EPA) developed a draft State-of-the-Science Evaluation: Nonmonotonic Dose Responses as they Apply to Estrogen, Androgen, and Thyroid Pathways and EPA Testing and Assessment Procedures. EPA asked the National Research Council to conduct an independent review of this evaluation to ensure that it is scientifically sound and of high quality. Review of Environmental Protection Agency's State-of-the-Science Evaluation of Nonmonotonic Dose-Response as they Apply to Endocrine Disrupters evaluates whether EPA's evaluation presents a scientifically sound and high-quality analysis of the literature on NMDRs. This report reviews how well the EPA evaluation described how the assessment was performed, whether consistent methods and criteria were applied in the analysis of different evidence streams, and whether appropriate methods were applied to evaluating the evidence. The report makes recommendations to improve EPA's process and strengthen the evaluation.
Advances in the life sciences - from the human genome to biotechnology to personalized medicine and sustainable communities - have profound implications for the well-being of society and the natural world. Improved public understanding of such scientific advances has the potential to benefit both individuals and society through enhanced quality of life and environmental protection, improved K-12 and undergraduate science education, greater understanding of human connections to the natural world, and more sustainable policies and regulations. Yet few systems of support exist to help life scientist communicators share their research with a broad range of public audiences, or engage the public in discussions about their work. Sustainable Infrastructures for Life Science Communication is the summary of a two-part workshop convened in December 2013 and January 2014 by the National Research Council Roundtable on Public Interfaces of the Life Sciences to identify infrastructure-related barriers that inhibit or prohibit life scientists from communicating about their work and characteristics of infrastructure that facilitate or encourage scientists to engage with public audiences. The workshop featured both formal presentations and panel discussions among participants from academia, industry, journalism, the federal government, and nonprofit organizations. The presentations highlighted the motivations of and challenges to life scientist communicators, theoretical approaches to science communication, examples of different types of infrastructure to support science communication, and the need for building more sustainable science communication infrastructures. This report considers communication infrastructure across a range of life science institutions, including federal agencies, academia, industry, and nonprofit organizations and explores novel approaches to facilitate effective science communication.

The quality of engineering in the United States will only be as good as the quality of the engineers doing it. The recruitment and retention of talented young people into engineering therefore need to be top national priorities, given the crucial importance of engineering to our prosperity, security, health, and well-being. Only 4.4 percent of the undergraduate degrees awarded by US colleges and universities are in engineering, compared with 13 percent in key European countries (the United Kingdom, Sweden, Finland, Denmark, Germany, and France) and 23 percent in key Asian countries (India, Japan, China, Taiwan, South Korea, and Singapore). In the past, the United States has been able to attract engineering graduate students and professionals from other countries to meet the need for engineering talent in the public and private sectors. But other countries are providing increasingly attractive opportunities for engineers, with excellent salaries, facilities, and economic growth potential. The United States can no longer assume that the best engineering talent in the world will want to come to this country. The Importance of Engineering Talent to the Prosperity and Security of the Nation is the summary of a forum held during the National Academy of Engineering's 2013 Annual Meeting. Speakers discussed the opportunities and challenges of creation and wise use of engineering talent, and made recommendations for recruitment and retention strategies. This report assesses the status of engineering education in the U.S. and makes recommendations to promote and improve engineering education.
The National Assessment of Educational Progress (NAEP) - often called "The Nation's Report Card" - is the largest nationally representative and continuing assessment of what students in public and private schools in the United States know and can do in various subjects and has provided policy makers and the public with invaluable information on U.S. students for more than 50 years. Unique in the information it provides, NAEP is the nation's only mechanism for tracking student achievement over time and comparing trends across states and districts for all students and important student groups (e.g., by race, sex, English learner status, disability status, family poverty status). While the program helps educators, policymakers, and the public understand these educational outcomes, the program has incurred substantially increased costs in recent years and now costs about $175.2 million per year. A Pragmatic Future for NAEP: Containing Costs and Updating Technologies recommends changes to bolster the future success of the program by identifying areas where federal administrators could take advantage of savings, such as new technological tools and platforms as well as efforts to use local administration and deployment for the tests. Additionally, the report recommends areas where the program should clearly communicate about spending and undertake efforts to streamline management. The report also provides recommendations to increase the visibility and coherence of NAEP's research activities.
From daily commutes to cross-country road trips, millions of light-duty vehicles are on the road every day. The transportation sector is one of the United States' largest sources of greenhouse gas emissions, and fuel is an important cost for drivers. The period from 2025-2035 could bring the most fundamental transformation in the 100-plus year history of the automobile. Battery electric vehicle costs are likely to fall and reach parity with internal combustion engine vehicles. New generations of fuel cell vehicles will be produced. Connected and automated vehicle technologies will become more common, including likely deployment of some fully automated vehicles. These new categories of vehicles will for the first time assume a major portion of new vehicle sales, while internal combustion engine vehicles with improved powertrain, design, and aerodynamics will continue to be an important part of new vehicle sales and fuel economy improvement. This study is a technical evaluation of the potential for internal combustion engine, hybrid, battery electric, fuel cell, nonpowertrain, and connected and automated vehicle technologies to contribute to efficiency in 2025-2035. In addition to making findings and recommendations related to technology cost and capabilities, Assessment of Technologies for Improving Light-Duty Vehicle Fuel Economy - 2025-2035 considers the impacts of changes in consumer behavior and regulatory regimes.
The National Academies of Sciences, Engineering, and Medicine convened a workshop on February 4th and 5th, 2021 to review the issues related to safety of passengers and employees in commercial air transportation, for domestic and international travel, during the COVID-19 pandemic. The workshop explored best practices to assess and mitigate COVID-19 transmission risks experienced during the travel chain, from the departure airport entrance to the destination airport exit. The workshop also identified areas where more research is needed to address gaps in understanding. This publication documents the presentations and discussions held during the workshop, and is presented as a synthesis of the workshop.
The National Institutes of Health (NIH) asked the National Academies of Sciences, Engineering, and Medicine to conduct a quadrennial review of its Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs, in accordance with a legislative mandate. Using quantitative and qualitative analyses of data, this report reviews the operations and outcomes stemming from NIH's SBIR/STTR awards. Drawing on published research and conducting new analyses based on both publicly available data and applicant data provided by NIH, Assessment of the SBIR and STTR Programs at the National Institutes of Health analyzes (1) the effectiveness of NIH's processes and procedures for selecting SBIR and STTR awardees; (2) the effectiveness of NIH's outreach to increase SBIR and STTR applications from small businesses that are new to the programs, from underrepresented states, and from woman-owned and minority-owned businesses; (3) collaborations between small businesses and research institutions resulting from the programs; and (4) a range of direct economic and health care impacts attributable to the programs.
While the world continues to respond to the COVID-19 pandemic, novel influenza viruses persist as a constant pandemic threat. The global response to COVID-19 has pushed the boundaries on what is possible for rapid pandemic response in several areas, including vaccine research, development, manufacturing, equitable distribution, allocation, and administration. If well understood and sufficiently adapted, these actions could be applied to future pandemic and seasonal influenza vaccine preparedness efforts. However, developing and delivering these more effective vaccines to meet the demand goes beyond simply technical challenges and includes issues across governance, financing, research, supply chain, and public engagement. To address these challenges, the National Academies of Sciences, Engineering, and Medicine convened a virtual public workshop in May of 2021 to discuss the emerging evidence on unprecedented actions related to COVID-19 that could inform and advance pandemic and seasonal influenza vaccine preparedness efforts and subsequent response. This Proceedings of a Workshop provides a high-level summary of the presentations and discussions that occurred during the workshop.
Surmounting the Barriers: Ethnic Diversity in Engineering Education is the summary of a workshop held in September 2013 to take a fresh look at the impediments to greater diversification in engineering education. The workshop brought together educators in engineering from two- and four-year colleges and staff members from the three sponsoring organizations: the National Science Foundation, the National Academy of Engineering and the American Society for Engineering Education. While the goal of diversifying engineering education has long been recognized, studied, and subjected to attempted interventions, progress has been fitful and slow. This report discusses reasons why past recommendations to improve diversity had not been adopted in full or in part. Surmounting the Barriers identifies a series of key impediments, including a lack of incentives for faculty and institutions; inadequate or only short-term financial support; an unsupportive institutional and faculty culture and environment; a lack of institutional and constituent engagement; and inadequate assessments, metrics, and data tracking. The report also shares success stories about instances where barriers to diversity have been identified and surmounted, and the resources that could enable real solutions to implement steps toward progress.
The United States has long made substantial investments in clinical research with the goal of improving the health and well-being of our nation. There is no doubt that these investments have contributed significantly to treating and preventing disease and extending human life. Nevertheless, clinical research faces a critical shortcoming. Currently, large swaths of the U.S. population, and those that often face the greatest health challenges, are less able to benefit from these discoveries because they are not adequately represented in clinical research studies. While progress has been made with representation of white women in clinical trials and clinical research, there has been little progress in the last three decades to increase participation of racial and ethnic minority population groups. This underrepresentation is compounding health disparities, with serious consequences for underrepresented groups and for the nation. At the request of Congress, Improving Representation in Clinical Trials and Research: Building Research Equity for Women and Underrepresented Groups identifies policies, procedures, programs, or projects aimed at increasing the inclusion of these groups in clinical research and the specific strategies used by those conducting clinical trials and clinical and translational research to improve diversity and inclusion. This report models the potential economic benefits of full inclusion of men, women, and racial and ethnic groups in clinical research and highlights new programs and interventions in medical centers and other clinical settings designed to increase participation.
New research in psychology, neuroscience, cognitive science, and other fields is published every day, but the gap between what is known and the capacity to act on that knowledge has never been larger. Scholars and nonscholars alike face the problem of how to organize knowledge and to integrate new observations with what is already known. Ontologies - formal, explicit specifications of the meaning of the concepts and entities that scientists study - provide a way to address these and other challenges, and thus to accelerate progress in behavioral research and its application. Ontologies help researchers precisely define behavioral phenomena and how they relate to each other and reliably classify them. They help researchers identify the inconsistent use of definitions, labels, and measures and provide the basis for sharing knowledge across diverse approaches and methodologies. Although ontologies are an ancient idea, modern researchers rely on them to codify research terms and findings in computer-readable formats and work with large datasets and computer-based analytic techniques. Ontologies in the Behavioral Sciences: Accelerating Research and the Spread of Knowledge describes how ontologies support science and its application to real-world problems. This report details how ontologies function, how they can be engineered to better support the behavioral sciences, and the resources needed to sustain their development and use to help ensure the maximum benefit from investment in behavioral science research.
