Climate change has increased concern over possible changes in Earth’s physical climate system, including its atmosphere, land surfaces, and oceans. Some of these changes could occur abruptly—within a few decades or even years—leaving little time for society and ecosystems to adapt. In a new report, an expert panel assembled by the National Research Council summarizes the current state of knowledge about abrupt climate change.
The nation’s transportation systems have a profound impact on our economy, quality of life, and resilience to disasters. Roadways, railways, airways, ports and waterways, public transit systems, pipelines, bike paths and sidewalks are the lifeblood of modern society.
The National Academy of Engineering (NAE) launched a new website for its Frontiers of Engineering Education program, which brings together some of the nation’s most engaged and innovative engineering educators in order to recognize, reward, and promote effective, substantive, and inspirational engineering education.
Concerns over the contributions of fossil fuels to pollution and climate change, in addition to other factors, have led to policies that encourage the development of renewable sources of energy such as biofuels. As biofuels become more prevalent, it is important to understand how such policies may impact human health.
Past research has suggested that memories are somewhat dynamic, rather than being set in stone. As a result, people can develop “memories” of events that never actually happened. A new study published in Proceedings of the National Academy of Sciences (PNAS) used MRI brain scanning to pinpoint the region of the brain responsible for flexible memory processes that allow people to revise memories to include new (and sometimes false) information.
The Global Network of Science Academies (IAP) and the InterAcademy Medical Panel (IAMP) recently issued a joint statement on "Antimicrobial Resistance: A Call for Action" highlighting the critical role that antimicrobial drugs play in today's medical practices and drawing attention to the dramatic increases in the number of pathogens developing resistance to these drugs.
Among the recipients of the 2013 Presidential Medal of Freedom are Daniel Kahneman, a member of the National Academy of Sciences (NAS) and Mario Molina, a member of the NAS and the Institute of Medicine (IOM). The Presidential Medal of Freedom, awarded this year on Nov. 20 at the White House, is the nation's highest civilian honor. It is presented to individuals who have made especially meritorious contributions to the security or national interests of the United States, to world peace, or to cultural or other significant public or private endeavors.
Although reconstruction of physical infrastructure such as roads, bridges, and houses is often the most visible aspect of post-disaster recovery, reconstruction and improvement of public health, medical, and social services plays an important role in overall community recovery.
Many National Academies studies have examined the evidence, causes, and impacts of climate change. At the heart of efforts to understand and respond to climate change are scientific models that allow us to piece together the Earth’s past climate patterns, understand current trends, and predict future climate variations. Explore these Academies resources for a window into the methods used to produce and apply climate models:
The 9th annual meeting of the African Science Academies recently convened officials of national science academies in Africa, Europe, and the U.S., as well as policymakers and researchers from around the world, to discuss the role of biotechnology in Africa's development.
