National laboratories are research facilities funded by the government, primarily in the United States. They focus on scientific research and development in various fields, including energy, environmental science, and national security. These labs often collaborate with universities, private companies, and other research institutions to advance technology and innovation. The Department of Energy oversees many national laboratories, such as Los Alamos National Laboratory and Oak Ridge National Laboratory. These facilities conduct experiments, develop new technologies, and provide expertise to address complex challenges facing the nation, contributing to both scientific knowledge and practical applications.
