Undark is a non-profit digital magazine that focuses on the intersection of science and society.

They accept pitches from professional freelance writers — and pay professional rates. Payment reports indicate payment of around 50 cents per word, or $500 per article, and sometimes more, depending on the project.

According to their about us page:

“As journalists, we recognize that science can often be politically, economically and ethically fraught, even as it captures the imagination and showcases the astonishing scope of human endeavor. Undark will therefore aim to explore science in both light and shadow, and to bring that exploration to a broad, international audience.”

They publish “a mix of long-form, narrative-driven journalism, shorter features, profiles, essays, op-eds, book excerpts, Q&A’s, reviews, blog posts, photography, digital video, information graphics and data visualizations.”
