Attribution of Extreme Weather Events in the Context of Climate Change (2016)

A report from the National Academies of Sciences, Engineering, and Medicine concludes it is now possible to estimate the influence of climate change on some types of extreme events. The science of extreme event attribution has advanced rapidly in recent years, giving new insight to the ways that human-caused climate change can influence the magnitude or frequency of some extreme weather events. This report examines the current state of science o... More >>

Effective Chemistry Communication in Informal Environments (2016)

Chemistry plays a critical role in daily life, impacting areas such as medicine and health, consumer products, energy production, the ecosystem, and many other areas. Communicating about chemistry in informal environments has the potential to raise public interest and understanding of chemistry around the world. However, the chemistry community lacks a cohesive, evidence-based guide for designing effective communication activities. This repor... More >>

Refinements to the Methods for Developing Spacecraft Exposure Guidelines (2016)

Human spaceflight is inherently risky, with numerous potential hazards posed at each phase of a mission. Some of the potential health risks arise from the effects of microgravity on the body and from the environmental conditions associated with living and working in spacecraft. Several hundred chemicals are likely to be found in the closed environment of the spacecraft, and as the frequency, complexity, and duration of human spaceflight... More >>

Review of the U.S. Global Change Research Program's Update to the Strategic Plan Document (2016)

This report reviews a draft update to the U.S. Global Change Research Program's 2012 Strategic Plan, finding that overall the Program is moving forward well and that the draft Update identifies a number of critical research questions and strategies to address needs for science-based information on global change. However, the report notes that the draft Update does not yet outline priorities for meeting urgent information needs, nor does i... More >>

Reducing the Use of Highly Enriched Uranium in Civilian Research Reactors (2016)

Since 1978, U.S. policy and programs have sought to minimize or phase out the use of highly enriched uranium fuel in civilian research and test reactors around the world to prevent the misuse of the fuel to make nuclear weapons. Despite some progress, converting the remaining research reactors to less proliferation-prone low enriched uranium fuel has proven to be a slow process. This report identifies successes and challenges that remain in th... More >>
