The third interview discussing preprints in the Global South features Alex Mendonça (interviewed by the 2025 ASAPio Fellow Tolulope Ogunniyi), who discusses the important work of @scielo.org Preprints in improving preprint submission and sharing across Latin America—particularly in Brazil.

Very much enjoyed last week's meeting in Cambridge about the Publish-Review-Curate (PRC) model for scholarly publishing. There were lots of highly inspiring discussions, including an important discussion about strengthening coordination between initiatives in this area. asapbio.org/reimagining-...

Rapidly-growing research and data demands have prompted many institutions to develop cross-functional models that combine the strengths of libraries, IT, research computing, and research administration. 🏛️ Four institutions reflect on building cross-campus collaborations:

We just preprinted a huge meta-meta-analysis examining the effects of exercise on cognition, memory, and executive function In short - 2239 effect sizes - extreme between-study heterogeneity - extensive publication bias - some subgroup/exercise-specific effects More below (doi.org/10.31234/osf...)

🚧 OSF Planned Maintenance The OSF will be unavailable today (Wednesday, December 10) from 7:00–10:00 p.m. ET / 00:00–03:00 UTC (Thursday, December 11).

Search for papers on reproducibility, replicability, or robustness and you’ll find plenty of results—and plenty of inconsistency in how those terms are used. A new COS blog by Brian Nosek shares SCORE’s working definitions and links to a short preprint with more detail. www.cos.io/blog/increas...

💻🤖 What does it mean to be "machine-first FAIR"? And how can this benefit research conducted by (and for) humans? Our VP of #OpenResearch, Mark Hahnel, shares why we need to embrace the #AI research revolution with open & #FAIRdata. 🔗 Read his post: https://ow.ly/e7oe50XAtht#OpenResearch#AI#FAIRdata#AcademicSky

Random colleagues in other disciplines now commonly say "the code's on OSF". It's just so great to see an academic org like COS, that goes beyond advocating for change, and actually builds the tools and services that make science work better. More!

Over the past decade, COS has worked closely with partners across Europe. We’re now starting the process of establishing a formal presence in the EU to deepen that collaboration while continuing to support researchers worldwide. Read more: www.cos.io/blog/expandi...

In 2024, DataSeer and @cos.io entered into a partnership designed to help support COS’ pioneering Lifecycle Journal. A little over a year after our partnership began, published articles that have undergone customized DataSeer checks are now appearing in the journal! dataseer.ai/2025/12/02/r...

Each year, hundreds of people donate to COS, helping keep OSF free and strengthening our open scholarship training and community support across research fields. This #GivingTuesday, we’d be grateful for your support: www.cos.io/support-yef25.

ASAPbio Fellow Fotis Mystakopoulos @elibrarydude.bsky.social spoke with Ashley Farley @openaccessmaven.bsky.social, Senior Officer of Knowledge and Research Services at the Gates Foundation, about how a major funder is accelerating open science through preprints. buff.ly/KR2lbjg

👏Congratulations to all the winners, including SIPS co-founder Simine Vazire @simine.com , who was recognized for "pioneering methodological rigor, reproducibility, and collaborative research in psychology."🏆

In Psychology Today, @ijzerman.bsky.social examines why citation counts are poor signals of research quality, highlighting COS-developed TOP Factor as a better alternative. TOP "measures whether journals implement practices that make research transparent and verifiable" 💡

PsyArXiv is pleased to welcome new member institutions! ✨Eindhoven University of Technology ✨New York University ✨Tilburg University ✨University College London Member institutions are integral to helping PsyArXiv deliver preprint posting and reading to its users at no charge.

Better together, indeed! Learn how @researchorgs.bsky.social and @orcid.org's systems interact and complement each other enhancing data quality and adding valuable trust markers to researchers’ records. buff.ly/daQAyWQ

Turning abstract policy into real-world practice is challenging, and sometimes messy. In the coming months, COS will highlight how we and other in the research community are putting the TOP Guidelines into action in real research settings. 💡 Learn more in our blog post:

“Simine Vazire talks the talk and walks the walk,” writes @briannosek.bsky.social @cos.io. 🏆 The €150,000 award allows her to continue prioritizing research rigor and honors the mentors, colleagues, and students who made her work possible. Short interview: www.youtube.com/watch?v=0H3g... (3/4)

If you want your work to be reproducible, you have to remember that others don't have the insider knowledge you have. You have to be explicit. This morning I was able to recreate a file made by someone else because they explicitly documented their definitions, calculations, and their assumptions. 🫶

All of the teams did better than randomly selecting scores and none of the teams did better than selecting 0.5 as a constant score. Round 2 is getting started. If you think you can do better, join! Prizes: $15k for 1st, $12k for 2nd, $6,750 for 3rd. More info: www.cos.io/blog/predict...

Round 1 results of our predicting replicability challenge are released! The Challenge capitalizes on interest in using AI methods to do scientific tasks. Ten teams tried to predict replication outcomes from unreleased SCORE findings. Results? Not so hot! Post: www.cos.io/blog/predict...

Earlier this year, COS launched the Predicting Replicability Challenge, a public competition to advance automated assessment of research claims. Round 1 results are now available! New teams are welcome to join for Round 2. 📊 Read more on our blog :

Why post a preprint instead of waiting for peer review? You get your work out fast, claim research priority, and protect it against plagiarism. Plus, they’re open access! Boosting your visibility and impact. Curious? Learn how preprints can work for you👇 #Preprints #OpenAccess #PhDsky

One year ago we launched the MetaROR (MetaResearch Open Review) publish-review-curate platform. This has been one of the most exciting things I've been involved in over the past year. Very grateful to everyone who has contributed to the development of MetaROR!

"By grounding TOP 2025 implementation in real world scenarios led by ourselves and other organizations, we hope to galvanize greater action across the research community — and invite the community to join us in implementing the TOP Guidelines in their policies." 🎉

Super exciting to see COS committing to putting TOP into practice in its own roles as a publisher, funder, and research performing organization. I'm particularly looking forward to seeing the implementation for the research team - so much great metascience coming out of this group.

Academic libraries play a key role in open science support, but what does that look like in practice? COS convened librarians & research professionals to discuss how they partner w/ researchers, administrators, & others to grow open scholarship awareness & participation. 📚:

@rnls.bsky.social is kicking us off! Why is #ResearchAssessment so important?
