Sad to see, but sounds necessary. The cost of maintaining all current features of OSF would be $4-5 million/yr -- far more than I ever realized. This should serve as a reminder to us all that open science is not a service an external group provides, it's a responsibility that lies with all of us.

Over the next several months, we will phase out some popular OSF features. These changes do not affect current public content, which remains safe and accessible. We have prepared support material to help users adapt. I am very sorry for the disruption to your work. Please read this post for details.

As a proud SIPS member since 2019, receiving a SIPS Commendation for ManyBeds means a great deal to me ♥️ A huge thank you to SIPS and to the kind person who nominated our project – whoever you are! 🙏 Make sure to check out the other commended and awarded projects as well. They’re doing amazing work!

Congratulations to the project “ManyBeds,” which received🏆2026 SIPS commendation! The ManyBeds project is a Big Team Science study that utilizes multi-site data collection and a many-analysts approach to test whether sounds played during sleep can reliably strengthen memories. buff.ly/nXEl73t

Puzzled that an #lme4 model that didn't converge before now reported no issues, I found that as of lme4 1.1-38, "derivative-based convergence checks are now skipped for models with large data". I can't find any more information - what's best practice here? Assume the model is "fine"? 1/3 #rstats

preprint alert 🚨 1/ Can we accurately detect sequential replay in humans using Temporally Delayed Linear Modelling (#TDLM)? In our recent study, we could not find any replay and decided to dig deeper by running a hybrid simulation with surprising results. Link to preprint & details below 👇

Proud to share this new meta-science article—our analysis of 255 preclinical opioid addiction studies highlights a pressing need for better transparency and reproducibility. Big thanks to Justine Blackwell and @alexh.bsky.social – it was an honor working with you on this project! :)

Alarming results in our new metascience article. NO cases of study preregistration and NO cases where authors shared their analysis code, across all 255 articles we found using animal models of opioid addiction from 2019-2023 onlinelibrary.wiley.com/doi/full/10....

🚨 Deadline extended: We’ve set the #ManyBeds registration deadline to August 31st! 🗓️ If you're interested in contributing to sleep and memory research, there’s still time to get involved. 🧠💤 Join us and help advance this important work. Sign up now! 👇

An article about data visualization was retracted 1.5 years after I pointed out errors. The notice says that "concerns were raised". I spend dozens of hours contacting authors and editors, reproducing analyses, and following up on ignored emails. But I'm not mentioned in the retraction notice.
