This template was developed by Overleaf and the National Academy of Science to allow authors to prepare and edit their Contributed or Direct Submission manuscripts.

The template will work for both regular and Plus research reports.

Additional instructions for direct submission and editing on Overleaf are included. The original template is available here:
