Amazing dataset describing the metabolic profiles of 66 E. coli transporter knockouts by @sulheim.bsky.social with Peter Doubleday and @nzamboni.bsky.social. The tool, set up by @lambdapp.bsky.social and Eric Ulrich allows you to explore for yourself. Enjoy! Pre-print here: doi.org/10.1101/2025...

This project wouldn't been possible without Peter Doubleday and @nzamboni.bsky.social at @imsb-eth.bsky.social. Peter conducted >10,000 mass spec analyses 🤯. So grateful for this opportunity to team up with the best of the best in metabolomics 😍 Read more: www.biorxiv.org/content/10.1... #microsky

We are beyond happy to see so many contributions from the #SIRIUScommunity at tat #Metabolomics2025. Don't miss the opportunity to get in touch and gain first-hand insights how you can integrate SIRIUS into your annotation workflow.

I've been asked about my slides on the #ZenoTOF8600. We uploaded the poster, which includes the data and comments, plus all key data and results at polybox.ethz.ch/index.php/s/.... Feel free to reshare or to ping me for more.

This was funny until I realized I am the one who has to prove it. 👀👀

A study using an n=1 experiment with single standards at 0V CID reported that 70% of detected ions were in-source fragments (ISFs). www.nature.com/articles/s42... This finding was extrapolated to suggest that ISFs affect all metabolomics experiments to this degree. A counterpoint. rdcu.be/ebFwc 1/n

I'm happy to share a correspondence in @naturemetabolism.bsky.social in which I was involved. #metabolomics #lipidomics www.nature.com/articles/s42...
