Funding of science
Research funding is a term generally covering any funding for scientific research, in the areas of natural science, technology, and social science. Different methods can be used to disburse funding, but the term often connotes funding obtained through a competitive process, in which potential research projects are evaluated and only the most promising receive funding. It is often measured via Gross domestic expenditure on R&D (GERD). Most research funding comes from two major sources: corporations (through research and development departments) and government (primarily carried out through universities and specialized government agencies; often known as research councils). A smaller amount of scientific research is funded by charitable foundations, especially in relation to developing cures for diseases such as cancer, malaria, and AIDS.
