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
30.05.2025 14:16 โ ๐ 20 ๐ 7 ๐ฌ 2 ๐ 0This 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.

There's no detailed methodology and there's no chromatograms. This seems just impossible. What do we do about this sort of thing? #Metabolomics

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.

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.

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.
