Want to give a shout for the non-targeted LC-MS metabolomics food database 食レポ・植レポ・物レポ metabolites.in/foods created and maintained by Dr. Nozomu Sakurai at National Institute of Genetics in Japan. Over 200 foods (C18 column 90min gradient with MS2 and MS3 spectra)

I have experienced a very similar learning curve with the metabolomics - few compound berries in the metabolomic feature forest ;)

For all those people thinking that we should relax social distancing I give you exhibit A on what happened last time. We have to distance from one another until a vaccine or cure is found. Fact, not politics.

Just realized ... mzmine was 15 years old few days ago (counting by 1st paper): bit.ly/30ICblU First code written TurkuBioscience, and now, mainly thanks to Tomáš Pluskal who joined project few yrs later with new ideas, this is truly a community-driven effort.

A postdoc position available in my new lab. Excited to dive into the amazing chemistry that plants have developed over millions of years of evolution? Interested in metabolomics and computational tools? Ready to run a brand new ultra high-resolution mass spec? Send your CV! :)

Voting now open for the board of the Metabolomics Society-iety. See my statement of purpose for 1) Promoting inclusion/diversity, and 2) Advocating for open data sharing practices. RT/like/vote if you share these goals for the #metabolomics community. tinyurl.com/y3zppf3n

Wonderful 1st tweet of 2021. I'm excited & proud to announce that our method for urinary untargeted #metabolomics is on ChemRxiv bit.ly/2LkUSaU. 4-years in the making, this method offers an automated high-precision approach for urinary metabolomics. Input is most welcome

Dr. Biswapriya Misra Romanas Chaleckis @isabel_meister5 Pei Zhang Thank you so much! This one has been near & dear to our heart for many years now. The Herculean efforts by @isabel_meister5 & Romanas Chaleckis really demonstrate some of the challenges w/ large-scale untargeted #metabolomics. Not the least of which is data processing. Thank you MS-DIAL!

We (Ken-ichiro Kamei and @QadoRodi) put our 1st manuscript in collaboration with GIAR-KI lab (Romanas Chaleckis Craig Wheelock) in bioRxiv! "Spatiotemporal Determination of Metabolite Activities in Multiple Corneal Epithelium Barriers on a Chip" biorxiv.org/content/10.110… #organs_on_a_chip #MPS

We still have a position open for a new developer of the mzmine! Looking for a talented coder in Java who is interesting in advanced scientific applications.

Pre-metabolomics intro is really nice!

There is a PhD opportunity in my lab focused on the development of the mzmine. Please spread the word!

Signs of easing COVID-19 restrictions in Japan in everyday life - masks are voluntary in the gym since yesterday 😷—>😀 I was almost missing the previous hypoxic experiences today 😜

Why large majority of ESI mass spectra in libraries are in positive ionization mode (e.g., NIST 20 75% positive, 25% negative)? Legacy of low pH/reversed-phase?

N-acyl-glycines (C2-C23) look promising as RT calibrants (Novel Peak Shift Correction Method Based on the Retention Index for Peak Alignment in Untargeted Metabolomics | Analytical Chemistry pubs.acs.org/doi/full/10.10…). How stable are N-acyl-glycines?

This paper shows that exposure of the mother to exposome molecules found that are part of car tires and other rubber materials end up in the brains of the unborn.
