By deep characterisation of 186 N-glycan standards, we @thencfg.bsky.social have made the most comprehensive targeted LC-MS glycomic assay to date.
Non-reduced native glycan analysis is key.
We hope this enables anyone with QqQ and interest in #glycotime to measure specific N-glycan structures.

🚀 Over 1k public datasets in @pride-ebi.bsky.social now have direct links to GEO, unlocking matched transcriptomics data! Final stats are dropping this week, but this is a big step toward a unified way to annotate #multiomics and build cross-database references in #PRIDE. 🧬🔗 #FAIRdata

Fascinating article about a cluster of ALS cases. If you think about it, this is a situation in which the researchers skimmed a large number of variables and identified a correlate which is then considered the potential cause.>

I am re-sharing since I don't get the feeling anyone noticed this pearl of wisdom (not by me). People I know who frequently "win" at pitches/proposals are following the Heilmeier formula: from simple communicating up to presenting concisely on project webpages to full on proposals.
I have an abbreviated version of the Heilmeier Catechism written on a post it note on my computer (What, Who, What do w/it, Impact) and didn't know it was part of a formal thing. If you want to know the best way frame any pitch, this is how. 100% an IYKYK situation.

🦷 Enamel proteins identify a female Byzantine ascetic - challenging assumptions that extreme religious self-punishment was just for men.

In harsh, arid environments where DNA doesn't survive, proteins in tooth enamel can still reveal biological sex.

I am trying to curate available CO-IP MS data for a protein and am appalled and saddened by the number of publications without MS raw/search data. I did not think this would be the case! #TeamMassSpec

I took biochem in 2001, and for nearly 20 years read amino acid sequences daily… and I never knew Dayhoff named them or even the logic behind things like Q until last Friday (h/t Mike Janech). Also, this is another big Dayhoff moment for me. She was incredible!
