Today I mused that a good way to describe research in our lab is: sometimes I wish I had access to a real engineer, and sometimes @paleoproteomicist.bsky.social wishes he had access to a real bioinformatician

You mean there are people who actually turn their test circuits into PCBs instead of just leaving them on a breadboard forever?

I did it in my first humidity paper. Two fragmentation patterns from the same compound that trend in opposite directions vs. x, with different colors/symbols. Pretty straightforward pubs.acs.org/doi/abs/10.1...

Sometimes when I give lab tours to kids or just laymen I refer to DART as "the little leaf blower" and DESI as "the little pressure washer"

Which I can understand, but there should be a simple cutoff once you get to # of reviewers. (They won't do that because then people would wait as long as possible to click the "accept" link, hoping others do it first)

Last year a revised version was returned to me, and I kept scrolling, scrolling through reviewer comments...and I was the 8th reviewer. The paper wasn't that long or complicated! I thought editors had trouble finding reviewers?

The Delaware Valley Mass Spec Discussion Group is BACK!!
Join us at Villanova University on 3/17 for networking and a presentation by John Kellie with AstraZeneca.

I put through a purchase request to my admin team with an "estimated $300 tariff tax" on the quote a few days ago, but it hasn't been paid out yet. I wonder how much this will cost.

If you're at Pittcon in March, check out my symposium with Ralf Zimmermann: "100 Years of Photoionization Mass Spectrometry: History, Principles and Current Applications", Tuesday morning March 10. 4 speakers talk history and their original research

That's what happens when half of abstracts are submitted on the last day. But at least they extended the deadline to the 16th.

Sure you can teach your child to be interested in books, but then she'll get you sick and demand you read aloud all weekend with a sore throat instead of silently watching the Olympics

ASMS already has at least 3,584 abstract submissions. I was one of the earliest to submit at the end of December, and my collaborator's abstract just went through, so I subtracted our tracking numbers. And there's still ~8 hours to go!

Did you ever get annoyed that someone failed to cite your old work, only to remember that you never actually published it in a journal?

I watched the Brad Pitt move F1 on the plane (as the artists intended, no doubt). There's a blink-and-you'll miss it shot of GC vials in the round carousel of an Agilent autosampler. Fuel analysis, I guess, which doesn't exactly work in the context of the scene but is plausible

I have a couple ASMS shoulder bags, they are my standard laptop bag for travel. This morning a kid on the metro asked if my bag said mass spectroscopy, because they just learned about that in AP chemistry. I told him you say "spectrometry" or you'll sound like a 70-year-old organic chemist

Every time I fly in January I travel with the fascist contingent who have been touring the city all week. Last year it was the weekend after the inauguration; today it's right after the anti-choice March for Life

Sometimes you read an older paper that is pretty uncomplicated and you think, "well, someone had to do it first".

Other times you read an older paper and think, "like 5 other groups proved the same incremental thing in this 5-year span".

I've got a Chinese national presenting in my Pittcon symposium in March, and the process is underway.
