Another shipwreck at the bottom of the sea of blood proteomics.

This is great news, and I hope all vendors continue to support THE vendor neutral option for MS data. Regardless, it was a shame that Skyline went without funding for a year from SCIEX

My dream is that Skyline is funded by all vendors continuously. All of #teammassspec benefits from the arrangement

New preprint! We did a systematic comparison of proteases, digestion conditions, and labeling methods for histone PTM analysis by MS-based proteomics in the Yates lab at @scripps.edu.

TL;DR: you can get great results in ~3 h of sample prep. 🧡

We need to get more mass spec proteomics folks on here and increase the size of our cluster!

1. It was not an accident.
2. It was not a staffer.
3. While the president may have dementia his racism is not due to dementia.
4. He isn’t sorry. He means every racist thought he shares.
5. His base agrees with him.
6. He will do it again.
7. No one in power will hold him accountable.

Working late at night alone in the lab as a grad student. Wrenches in both hands and touched a bare heater wire in a high voltage instrument. I was across the room before I knew what happened.

Thanks for highlighting this diversity of analyzable tau mods. Our technology is wonderful now, but this advance kicks the problem back to us. How do we think about the relationship of diverse modifications to disease? The real challenge is to formulate new questions and testable hypotheses.

Our latest article is out in Cell !

Together with the Zernicka-Goetz lab, we show that fertilization triggers proteomic asymmetry in mammalian zygotes, giving rise to alpha vs. beta 2-cell blastomeres with distinct developmental potential.

β€˜A sigh of relief’: New malaria drug succeeds in large clinical trial As existing drugs falter because of resistance, the world gets a backupβ€”but hard choices loom on how to use it

I’ve been in Toronto at the #astmh meeting these past few days and last night some very good news was presented here: A new malaria drug has proven efficacious in a large trial and could soon be approved.πŸ§ͺ

MainersΒ defeat Republican effort to institute voter ID and limit absentee voting The no side of Question 1 had 60.2% of votes to 39.8% for the yes side when the Bangor Daily News and its national partner, Decision Desk HQ, called the race at 9:26 p.m. Tuesday.

Maine has voted in a landslide to reject a Republican-supported ballot initiative that would have restricted voting access heading into the critical 2026 midterms

Vanderbilt response to the Trump β€˜compact’ is too clever by half. Dodging the immoral dominance play and pretending it’s a reasoned conversation. Vandy wishes to play ball as an elite institution on a level with MIT, Penn and UVA. Struck out looking.

Speculation: There has been a recency bias in citations for a long time, because the newer work should contain more up-to-date knowledge.

This could reverse. People might increasingly refer to work before the 2020s, because it wouldn't have been corrupted by gen AI.

These shape-shifting rings create customizable cores 1,2-oxaborines can shift into 11 different ring shapes to make modifying molecular cores easy

Turns out, boron-based heterocycles are anything but boring! In fact, some of them are pretty magical...1,2-oxaborines, for example, can be used as precursors to 11(!) other ring systems!

People need to start highlighting that Miller is actually the shadow President and the one calling the shots. When it was Musk who was doing it, it caused a rift between them so big that after he was out, Musk was bashing Trump claiming he is in the Epstein files.
