Workshop
On June 11 and June 12, 2019, the National Academies convened a workshop to explore the growing understanding of how the interplay between humans and microbes affects host physiology and causes noncommunicable diseases. Discussions included an overview of colliding epidemics, emerging research on associations between infectious and noncommunicable diseases, risks posed by chronic diseases to the development and severity of infectious diseases, and the influence of the microbiome. Workshop participants also examined the challenges and opportunities of convergence, the integration of health care delivery models and interventions, potential approaches for research, policy, and practice in the immediate-term, and potential directions for the long-term. This publication summarizes the presentations and discussions from the workshop.

Workshop_in_brief
Obesity remains one of the most pressing public health challenges in the U.S., contributing to increased risks of chronic disease, mobility limitations, and health care costs. While physical activity is widely recognized as a cornerstone to prevent and treat obesity, questions remain about effective ways to integrate movement into clinical care and daily life - particularly in light of new obesity management medications, evolving technology, and diverse individual needs.
The National Academies' Roundtable on Obesity Solutions convened a workshop in July 2025 which explored physical activity not only as a mechanism for weight management but also as a critical component of holistic health and well-being. The workshop also examined the effectiveness of physical activity across prevention and treatment settings; integrating physical activity into clinical, community, and policy frameworks; and the influence of emerging technologies on obesity care. This Proceedings of a Workshop-In Brief summarizes discussions and presentations from the workshop.

Transit agencies use electrical traction (overhead catenary or third rail)—which is typically designed using high alternating-current or direct-current voltages—for the propulsion of trains. The running rails are used as part of the system to return negative power to substations. Insulated joints (IJs) are trackwork components installed in the rails to provide train control circuits and traction power segment separation between blocks.
TCRP Research Report 255: Investigation and Mitigation of Insulated Joint Electrical Failure: A Guide, from TRB's Transit Cooperative Research Program, provides information on how to identify arcing at IJs, methods to diagnose the contributing factors, underlying causes, strategies for investigating IJ failures, and examples of how others have mitigated arcing.

Billions of gallons of water per day are channeled from northern California to drier Central and Southern California through the network of dams, canals, and other features that comprise the federal Central Valley Project (CVP), operated by the U.S. Bureau of Reclamation (USBR), and the State Water Project (SWP), operated by the California Department of Water Resources. At least two thirds of California's population and more than 4 million acres of California farmland rely in whole or in part on water delivered by these projects. In addition to delivering water to meet diverse demands, the Projects must also protect six endangered fish species, including Delta smelt, longfin smelt, Sacramento River winter-run Chinook salmon, Central Valley spring-run Chinook salmon, California Central Valley steelhead, and the southern distinct population segment of North American green sturgeon.
At the request of the USBR, the National Academies of Sciences, Engineering, and Medicine established a committee to conduct a biennial review of the monitoring, modeling, and other relevant scientific activities of the CVP and the SWP. This first report in the series examines three actions designed to help protect the fish - the Shasta Coldwater Pool Management Action, the Old and Middle River Flow Management Action, and the Summer-Fall Habitat Action for Delta Smelt. The report evaluates the scientific basis for each of the actions, along with monitoring and modeling needs, and makes specific recommendations for strengthening each of them to help them reach their stated goals.

Individuals and families across the United States face growing challenges in accessing timely, high-quality primary care, which is essential to overall health and well-being. The delivery of such care is becoming more complex, placing undue strain on primary care clinicians and exacerbating existing workforce shortages.
A National Academies committee recently examined the inputs and functions needed for interprofessional teams to successfully and sustainably deliver high-quality primary care. The committee concluded the nation must support the primary care workforce through appropriate and supportive payment; hold payers, states, and health systems accountable in ensuring that such payment reaches primary care practices; and sufficiently train an interprofessional workforce. This report offers nine specific recommendations for how federal agencies and other key players can better support the provision of high-quality, interprofessional, team-based primary care.

The Gulf of Alaska and the Southern Gulf Coast have been the sites of the two worst oil spills in U.S. history, Exxon Valdez (1989) and Deepwater Horizon (2010), respectively. These spills had devastating impacts on the environment, human health, the local economy, the seafood industry, and local communities’ way of life. While the incidents differed in many ways, the response and recovery efforts both worked to restore the environment and help communities move on from their losses.
To explore best practices and lessons learned from these oil spills, the National Academies of Sciences, Engineering, and Medicine's Gulf Research Program launched a three-part workshop series to bring together people with connections to the Exxon Valdez and Deepwater Horizon oil spills to discuss the challenges, successes, and areas where improvements could be made. The first workshop was held in Anchorage, Alaska in October 2024; the second workshop was held in Thibodaux, Louisiana in December 2024; and the final workshop was held in Washington, D.C. in March of 2025. This publication summarizes the presentations and discussions of the workshops.

Military families raising children with autism often face unique challenges in accessing consistent, high-quality care across frequent moves and deployments. Applied behavior analysis, or ABA, is widely recognized as an effective intervention for many autistic individuals, yet military families report barriers that delay or restrict their access to these services.
The report The Comprehensive Autism Care Demonstration: Solutions for Military Families examines how the Department of Defense's autism care demonstration program is serving families and whether ABA should be covered as a TRICARE Basic benefit. Drawing on a careful review of the scientific literature, the report finds that ABA meets the Department's own standards for reliable medical evidence and should be formally authorized as a TRICARE Basic benefit.
The report identifies key areas where current demonstration policies differ from clinical standards. These include restrictive rules around assessments, limited flexibility in treatment goals and settings, and administrative requirements that impose unnecessary burdens on both families and ABA providers.
