I love molecules microbes make and mass spectrometry. I can spend hours looking at MS/MS with the dream we can annotate every molecule.

Such an amazing school of metabolomics in Brazil. Such a beautiful county. Thanks for the invite to describe why metabolomics is like reading a book with 93% of words missing.

Switching the clocks twice a year hurts Americans' health. A modeling study of county-level solar light patterns, time policy, health data, and circadian models suggests a permanent shift to Standard Time would reduce obesity and strokes. In PNAS: www.pnas.org/doi/10.1073/...

Such awesome day today at UC-Riverside. Got to spend time with two of my science children and their team (science grandchildren). Just so fun thanks to Ming for the pic. And got to go biking with @func-metabo-lab.bsky.social

HT SpaceM: A high-throughput and reproducible method for small-molecule single-cell metabolomics
Single-cell metabolomics (SCM) can probe metabolic heterogeneity but is hindered by
low sensitivity for small molecules, limited scalability, and the lack of standardized
frameworks for data analysis....

Yes reach out to Yasin for this project. It will allow a worldwide picture of the environmental metabolome. This can be already published or not yet published data but will need world coordinates.
Interested in a co-authorship?
We’re building a tool for repository-scale untargeted #metabolomics and #exposomics of #environmental data. To make it the best it can be, we’re looking for people willing to share high-resolution LC-MS/MS (DDA) data from #water, #soil, #sediment, and related samples.

He was such an amazing individual. Loved teaching in his course.
Saddened to learn of the passing of Moselio "Elio" Schaechter—Distinguished Professor at Tufts, SDSU and UCSD—humanist and visionary leader in the fields of microbiology and scientific communication—mentor, friend, and inspiration to me and so many others
