Center for Open Science

COS is announcing important changes to the Open Science Framework (OSF). OSF Projects—used for project collaboration, file mgmt, & storage—is being phased out as an active workspace over the next 6 months. This change does not affect persistence & accessibility of existing public projects. (🧵1/2)

Coming up! 💻 How to Use the OSF API Oct. 29 With OSF’s two APIs, users can glean valuable insights into research activities on OSF, and manage and automate tasks. This webinar will introduce you to OSF’s APIs and give you the basics to get started with them. Register: cos-io.zoom.us/webin...

During the talk, Ludo will outline a new vision for research communication based on the Publish, Review, Curate (PRC) model—one that places openness, transparency, community participation, and scholarly judgment at its core. Register: publish-review-curate.org/2026/09/07/l...

Join us for the “Publish, Review, Curate (PRC): Shaping the future of scholarly publishing” launch event, where Ludo Waltman @ludowaltman.bsky.social, Scientific Director, Center for Science and Technology Studies (CWTS) at Leiden University, will give a keynote talk.

The report identifies some key issues with equitable #OpenScience. 💰 Open access fees some authors can’t afford 👥 Standards that exclude some people ⚖️ Uneven infrastructural coverage 🏅 Unrewarded labour What else belongs on the list? www.researchprofessionalnews.com/rr-news-euro...

Medical Teacher is the first health professions education journal to adopt Registered Reports. In this model, study plans are peer-reviewed before data collection, with publication decisions based on methodological rigor rather than the nature of the findings. Read more: www.tandfonline.com/...

I've used the pre-registration template and I perceived it as very useful. I recommend it to all researchers working with choice experiments. Not only it serves #openscience, but further it helps you not to forget important design issues before implementation of the DCE.

"Estimators based on meta-analysis methods that correct for potential bias in the original study were close to unbiased when synthesizing the original study and replication...meta-analytic estimates were substantially closer to the effect size of the replication compared to the original study."

COS researchers and collaborators have developed and piloted Registered Revisions—an approach designed to reduce uncertainty and publication bias when substantive changes to a study’s analysis are requested during peer review Noah Haber previews what's in the report:

Running a metadata enrichment project in the open? COMET pilot teams refined a Project Doc Template to record objectives, collaborators, outputs and lessons learnt, so others can trust and reuse the work. Try it and tell us what you'd change. #ScholarlyMetadata #OpenResearchInformation

Our journal, book and chapter checklists help researchers assess where to publish and make informed choices. Different researchers need different formats. That’s why we’re delighted to launch an interactive journal checklist: bit.ly/47oYBLp

Up on the COS.io blog now: "What is in the Registered Revisions Meta Trial Development Report" www.cos.io/blog/what-is... Yeah this is a post about a post about a report. But it's an unusual report worth a read, since it focuses on all the lessons learned, dead ends, straight up errors, etc.
