There so much to learn what microbes are doing inside us. Glad to be part of this work, thanks to Pieter and the whole team.

It’s so nice that an important paper led by yasin - is out. www.nature.com/articles/s41.... This paper is a key milestone as it is the foundation for data science across data repositories through indexing and metadata harmonization of 1.6 million files (although much more now due to updates). 1/n

This paper represents a great effort by @roman-bushuiev.bsky.social and his brother @anton-bushuiev.bsky.social. The DreaMS foundation model for mass spectra of small molecules now opens lots of avenues for possible downstream applications. It might be a game changer for computational metabolomics.

I'm looking at a paper in a decent journal that claims to have separated glucose, mannose and fructose on a Waters C18 BEH column. There's no detailed methodology and there's no chromatograms. This seems just impossible. What do we do about this sort of thing? #Metabolomics

Free access to 2,656 metabolites from 9 platforms measured at 56 time points and covering 6 challenges "suffered" by 15 healthy volunteers: The HuMet Repository - Watching human metabolism at work www.sciencedirect.com/science/arti... All data provided in an interactive repository: humet.org

We thank all the co-authors - and many others that are not part of the paper - for the wonderful discussion on this topic. The discussion is an important education to the field and needs to be accurately presented - including existing computational solutions to handle.

Many discoveries will (probably have already) line up due to this crucial data driven strategy. Grateful to @pieterdorrestein.bsky.social and the entire team that i could contribute and be part of this very important data driven reverse #metabolomics workflow led by @vincentlamoureux.bsky.social

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

It’s not every day one gets to publish an article with NASA astronauts. This journey started in 2019 and withe the goal to understand the microbial and chemical make-up of the space station. We had lots of experience with analysis from swabs on earth.

Early in life, secondary bile acids are generated by colonizing microbes, associated with risks of immune-mediated diseases and act as immunomodulatory substances. Great collaborative study now online!

Happy to share this preprint from our team, great collaboration with Mikael Knip, @pieterdorrestein.bsky.social, @lahesmaalab.bsky.social, and @petterbrodin.bsky.social . Special kudos to @santoshlamichhane.bsky.social. www.medrxiv.org/content/10.1... #T1D #bileacids #autoimmunity #metabolomics

This is such nice work, glad we could be part of it. Is shows how microbial bile acid amidates that differs in diabetic infants during their development could lead to immune dysbiosis.

Check out our new #preprint, a collaborative effort to explore emerging #bile acids (also referred as MCBAs) during early life. Briefly, here we analyzed MCBAs in early life and found distinct age-related trajectories linked to gut #microbiota, #immune modulation & islet #autoimmunity progression.

Important #PFAS news - Independent experts convened by the WHO's International Agency for Research on Cancer have classified #PFOA as carcinogenic to humans (Group 1) and #PFOS possibly carcinogenic to humans (Group 2B). In the past, manufacturers' mercenary scientists have questioned that evidence.

How does metabolomics help agriculture? Human health? A brief overview of this fungal metabolite-Fumonisin B2- shows the importance of this overlap. Check out more at cmmc.gnps2.org Another impactful study of this metabolite: pubs.acs.org/doi/full/10.1021/jf0718906

Our latest article "Data sharing restrictions are hampering precision health in the EU" Here is the open acces link: rdcu.be/d6Bgd #precisionmedicine 🧬💊🧪

Here the authors used molecular networking to discover PFASs and reanalyze public data sets to show they are observed in data from seven countries. Such a nice reuse of public data - but also alarming as they are seen in data going back to 2005. www.nature.com/articles/s41...
