SciLine is supported by philanthropies that are committed to open and accurate communication among scientists, journalists, and the public as an essential ingredient of evidence-based decision-making and of democracy itself.

Generous founding and sustaining support for SciLine has been provided by the Quadrivium Foundation, with additional support from the Chan Zuckerberg Initiative, the John S. and James L. Knight Foundation, the Rita Allen Foundation, the Schmidt Family Foundation, the Google News Initiative, the Alfred P. Sloan Foundation, the Heinz Endowments, the Zakaria Family Foundation, and the Leo Model Foundation.

SciLine is based at and receives in-kind support from the nonprofit American Association for the Advancement of Science (AAAS). SciLine is editorially independent from its funders and from AAAS business operations, including its journals and EurekAlert!, the science news-release distribution service.
