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

Excited to see science from @pieterdorrestein.bsky.social, @mfgrp.bsky.social, @inesthiele.bsky.social, @contaminatedsci.bsky.social and many others pushing the frontiers of microbiome research! #Microbiome #KeystoneSymposia

We are looking for a 3-year postdoc to work with Daniel Probst, Justin van der Hooft and myself on an exciting project involving federated learning and integrative omics for discovery of new antibiotics from natural products. Apply here: www.wur.nl/en/vacancy/p... Please share!

Good morning for a swim.

HT SpaceM: A high-throughput and reproducible method for small-molecule single-cell metabolomics #Cell #MassSpec www.cell.com/cell/fulltex...

It started with a concept of using data science and mass spectrometry for drug discovery with the goal to help people improve quality of their lives enveda.com. Now it’s a 🦄 that is getting a real shot at doing so with great clinical leads and in clinical trials www.youtube.com/watch?v=VafS....

Nice day on the bike. Great way to spend Labor Day week-end.

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.

So excited!

He was such an amazing individual. Loved teaching in his course.

The best of both worlds with awesome speakers that will focus on how the microbiome affects ecosystems at a mechanistic level. Can’t wait for this meeting.

When the original paper came out in 2010 I asked for the sims-ims data. They did not want to share. The journal did not serve the community well. It is not fraud but poor experiments - lack of experts in the experiments - and editorial process + hype. This is the right call by the journal.

New paper from the group. Together with Chambers Hughes, Giovanni Vitale and our amazing collaborators, we developed a multiplexed chemical metabolomics workflow to assign functional groups in non-targeted LC-MS/MS data: www.nature.com/articles/s41... Behind the paper story: go.nature.com/45ljV4d

Had a great time in the mountains with the family and friends. Glad the bear was not hungry as he was just 10 meters away from me when I turned the corner.

I am so excited about this meeting. I will cover the discovery of 10,000s new metabolites, including an entirely new class of molecules. Looking forward to hearing and discussing your science on microbiome metabolites and metabolism.

This is so nice!

At my 1st @femsmicro.org congress (in Milan!) - it's a fantastic meeting. I co-chaired a superb session on Microbial Dark Matter with @jlewillett.bsky.social, who also kicked off the session with a talk on her lab's work. 🤩 We also heard from my FEMS Microbes co-EIC Kathleen Scott! 💪🏽 #FEMS2025

Are you a top US-based scientist wanting to relocate to Australia? We are now calling for formal applications from both Australian and non-Australian citizens based in the US whose work is internationally recognised as exceptional. 📅 Applications close: Aug 29, 2025 🔗 science.org.au/gtap/?utm_so...

So fun when a post doc comes to you and shows a result where they have discovered an entirely new class of very common metabolites that have been right under our noses.

Fresh out! #microbiome #microsky #gastrosky

Sometimes one get’s to see results that just blow your mind and know instantly how impactful and transformative it is. Probably just got send by a post doc one of the most exciting results I have seen in my career - I LOVE science!! Paper will be hard to write but so fun and just wow.

Breakfast from our yard.

Good to be back biking in #SanDiego

Good news: the very low current levels of SARS-CoV-2 in wastewater, even in places where the new variants are prevalent (XFG, NB.1.8.1), suggest that any summer wave will be limited, not like previous ones www.cdc.gov/nwss/rv/COVI...

Good to be back from a great trip to the Netherlands with the family.

Great keynote by @sneumann.bsky.social at #MetSoc25, strongly advocating for #opensource , data-sharing, and making things interoperable. Glad to also spot #matchms in this universe :)

In this article published today in @metabolomicsj.bsky.social, we introduce the Korea MetAbolomics data rePository (KMAP), and describe what our team has pushed hard and what we will do, to make it standardized and harmonized with the other data repository. doi.org/10.1007/s113...

Was so good to be at the actinomycete meeting and see so many friends and co-workers- some I had not seen in a decade. Last time I attended this meeting was in 2011 and had introduced molecular networking. Now many are using it in this community to make discoveries.

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.

If you have ever wondered what might happen to short chain fatty acids made by the microbiome. Here is a large class of metabolites and how they link to biology. www.cell.com/cell/fulltex...

This is such an incredible paper. Must read if you care about metabolites and cores organ interactions. For me most interesting finding is that the liver is NOT the only organ that converts cholesterol to bile acids. But ther are so many cool onserbwtions www.cell.com/cell/abstrac...

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
