Glad to see this news story highlighting our recent lipid interactome database, a resource we hope will help the broader scientific community. @ohsummi.bsky.social @ohsunews.bsky.social news.ohsu.edu/2026/02/25/n...

New database may unlock potential of lipids in treating, preventing disease
OHSU scientists lead development of so-called ‘Google maps’ for how lipids interact with proteins inside cells.

Can we improve peer review? We think we can! Check out an experiment I helped with as part of @solvingforsci.bsky.social 's mission to make science better. And if you don't want to read the whole bioRxiv manuscript, here's an overview of the main findings: solvingfor.org/news-posts-d...

Federal funding of biomedical research has been a remarkably successful partnership, with benefits that are so intertwined in our daily lives that they can be easy to take for granted. So what will we lose if the U.S. continues to defund research? theconversation.com/cuts-to-scie...

Cuts to science research funding cut American lives short − federal support is essential for medical breakthroughs
The National Institutes of Health has been integral to scientific progress in treating countless human diseases. Without its support, patients will ultimately pay the price.
