#Julialang folks, did you check out Tachikoma.jl TUI framework yet? It looks pretty wild. I'm thinking of testing it out as a frontend for a bioinfo dashboard for a collaborator. Hope the author is planning on giving a talk at the upcoming JuliaCon! github.com/kahliburke/T...

This whole saga is amazing 1) Bot makes PR to matplotlib; it's closed as slop 2) Bot writes blog post attacking matplotlib maintainer 3) Ars Technica article about this 4) Article gets retracted for fake quotes (AI again!) 5) It was a crypto grift all along social.treehouse.systems/@ariadne/116...

Pyritised, metamorphosed, and faulted #Archean microbial mats from South Africa. I love the colours on this one. #geology #paleontology
The structure and detail in these Archean microbial mats from South Africa are fantastic. I could look at these all day. Deets in the alt text. #Geology #Paleontology
Here’s a really nice alluvial fan I thought you should see

For Day50 of photoshopping @lastweektonight.com's John Oliver with fossils in the hopes that he saves the Paleontological Research Institution Celebrating 90yrs of mollusk research at PRI! John is joined by a number of other H. sapiens who love science (and fun)-tag them all! 🧪🦑⚒️🐌 #fossils #savePRI
Day49 of photoshopping @lastweektonight.com's John Oliver with fossils in the hopes that he saves the Paleontological Research Institution For Father's day, John (H. sapiens) is showing us Vaderlimulus tricki (UCM 140.25), a very paternal(😉) horseshoe crab from Bicknell and Pates, 2020 #savePRI ⚒️🦑
I sometimes take advantage of the analytical equipment at my real job. This is a Cambrian arthropod (probably not a Beckwithia) from the Wheeler shale of Utah. I used the XRF (X-ray fluorescence) to highlight iron and phosphorus. This is a 500 Ma digestive system. #FossilFriday
I am pleased to announce that my department (EAS at Nebraska) is hiring a teaching postdoc for AY 2025-2026 in the area of Earth Materials! I'm not on the committee but am spreading the word to my mineralogy/petrology networks on behalf of the committee. See ad for more details.

Unsurprisingly, @tressiemcphd.bsky.social is spot-on in this analysis: “A.I.’s most revolutionary potential is helping experts apply their expertise better and faster. But for that to work, there has to be experts.” www.nytimes.com/2025/03/29/o...

A.I. is just what we need in the post-fact era: less research and more predicting what we want to hear.

We are assuming this was a planetary scientist traveling to the Lunar and Planetary Science Conference
Le Monde reporting that a French scientist traveling to Houston to attend a conference was denied entry to US after a search of his phone & computer revealed messages critical of Trump's science cuts, "which [says CPB] conveyed hatred of Trump & could be qualified as terrorism".

Who’s guilty of the discrepancy between minerals and whole-rock chemistry in plutons? Melt extraction might be innocent—mineral reequilibration is likely the real culprit! Fresh out on Pi Day by me, Brenhin @brenhinkeller.bsky.social, & Changqian! doi.org/10.1029/2024...

New: A NOAA lab in Hawaii that is connected to the longest-running observation of global greenhouse gas concentrations is slated for closure in August, according to a list of lease terminations Democratic members of Congress shared with @washingtonpost.com.
Trump moves to close government lab that tracks planet-warming pollution
The lab is connected to the Mauna Loa Observatory, where scientists gather data to produce the Keeling Curve, a chart on the daily status of atmospheric carbon dioxide concentrations.
