Copyright / DMCA
Scientific facts are explained in original language while copyrighted expression and imagery are respected.
Original editorial work
We do not copy journal articles, abstracts, news stories, charts, photographs or press releases. Short quotations are used sparingly when necessary and attributed.
Federal material
Many works created by U.S. federal employees as part of their official duties are not protected by U.S. copyright, but federal websites may also contain copyrighted third-party work. We verify the status of the specific material, follow requested attribution, avoid agency logos, and never imply government endorsement.
Facts and discoveries
Facts and scientific discoveries can be reported, but a source's particular wording, illustration, photograph, table or chart may be protected. Our normal practice is to extract verified facts, write a new explanation and link readers to the source.
Rights concerns
A rights holder may contact the editorial team with the page URL, identification of the work, contact information and a good-faith statement of the concern.
Response
We will review credible notices promptly and may remove or replace disputed material while the issue is investigated.
