We will probably elect at president who will yet again bend to the donor class and form a few committees about this stuff

If you spliced Charlie Kirk with a mouse and then turned the racism and sexism from 9.5 to 11 you'd get this guy

That's good to know, friend. I was getting a little mad, but now I realize that was silly.

This a word cloud from the titles of ~1100 terminated NSF grants.

It is hard not to see these grant terminations as an attack on the training of the future United States scientific workforce.

Getting mad at an old friend because he isn't as publicly mad about something as you are? You're better than that.

You fucking kidding me? There has been great concern. Maybe more so on social mediums though. Sorry for not meeting your threshold of concern

Because I live in the USA, I can't have an opinion about Iran? What Iranian friends and coworkers who have heard about friends, family, and colleagues not sure if they are dead or alive. The Iranians I know on social media think the 30K killed by Iranian government is underestimated.

Your take here is that because the US and Israeli governments are acting horrifically, this makes the government of Iran heroic? They are all bloodlusting oligarchs. Iran would kill as many Iranians as Israel has killed Palestinians if that's what it took for them to stay in power.

Isn't it remarkable to head into middle age and consider that for more than 75% of my life, my country has been led by someone who was (or is) a confirmed or suspected sex pest

Yes this is a Science account, but its also a political account because we can't do science if ICE shoots us in the street for protecting our fellow humans.

RINRUS: A Toolkit for the Construction of Reproducible and Reliable QM-Cluster Models of Enzyme Active Sites | ChemRxiv Effectively constructing an enzyme active site model is not only the most important task involved in quantum mechanical (QM) modeling of enzymes, it is also one of the most difficult. Without widely agreed-upon standards for selecting, truncating and ...

I am stoked to share the pre-print for our walkthrough and review of applications with RINRUS (residue interaction network residue selector) the Python package my group has been working on for ~10 years to standardize and automate QM-cluster model construction!

Theoretical Electronic Spectroscopy of Gas Phase Transition Metal Acetylide Cations (MCCH+, M = ScΒ·Β·Β·Zn) C2H radicals and CnH polyynes are among the most abundant interstellar polyatomic molecules, predominantly observed in molecular clouds and planetary nebulae. While the C2H– anion is considered a plausible component in the interstellar medium (ISM), it has not yet been detected. Given the extensive study of interstellar polyynes, MCCH/MCCH+ species are also expected to exist in the ISM. Via fundamental metal–carbon bonding, MCCH/MCCH+ molecules exhibit strong polarity, enhancing the intensity of their rotational transitions and improving the chances of astronomical observation. Theoretical spectroscopy enables the generation of molecular reference data to aid in detections. In this study, highly accurate single reference coupled cluster theory [CCSD(T)] is compared to multireference configuration interaction theory (MRCISD+Q) to survey the electronic structure of 3d metal mono acetylide cations (MCCH+, where M = Sc to Zn) which could catalyze gas phase reactions in cold astrochemical environments. CCSD(T) and MRCISD+Q theories gave equivalent predictions of ground electronic states for all cations excluding CoCCH+. The MRCISD+Q ground state for CoCCH+ (4Ξ¦) is multireference and multiconfigurational, and single reference coupled cluster energies could not be converged. The investigated electronic states of MCCH+ arise from interactions between the 1Ξ£+ ground state of the C2H– anion and the metal dication (M2+). A thorough analysis of multireference character of electronic states is reported. The 3Ξ  excited state of NiCCH+ was the variationally accessible electronic state with the strongest reported multireference character (T1 diagnostic = 0.15, D1 diagnostic = 0.55, C02 = 0.26). Harmonic vibrational frequencies, infrared intensities, and dipole moments are computed for the identified ground states. Theoretical characterization of the ground and excited electronic states of these specific ions will assist in their astronomical detection, constrain laser spectroscopy experiments of the neutral species, and guide characterization in synthetic laboratories.

holy moly, my 100th peer reviewed publication!!! We look at fundamental gas phase organometallic bonding with CCSD(T) and MRCI, get super accurate ionization energies of the 3d MCCH series, and find several challenging cases for electronic structure theory.

Thanks Jay. I'm perpetually hard on myself. I know I need to view this as valuable reading/writing/me-time, rather than as some kind of professional set of New Years resolutions that must change my entire life for the better. Are you planning on coming to SERMACS in Memphis in 2026?

About to embark on sabbatical next month, but conservatively planned due to family and funding constraints. I feel like I've already squandered the time and it hasn't even started yet. Anyone have tips on how to make the most of life?

AI should be used to make strong skills stronger, but we are training multiple generations of K-12+college+grad school that they should use AI to make their weak or non-existent skills strong... what could possibly go wrong?

One of the saddest part about going through Andrew Weatherall's DJ/radio set archive in reverse chronological order is that I have hit the late 90's, there are few full track listings, and suddenly Shazam can't ID any of the best tracks.

Isn't academia great? Yesterday I got my 100th paper accepted, nearly finished a grant proposal, started SERMACS mass emails, finished grading for the semester. Today I'm panicking about a collaborator who can't submit paperwork on time, and one of my grad students quit.
