The machines are fine. I'm worried about us. On AI agents, grunt work, and the part of science that isn't replaceable.

"The project isn't the deliverable. The project is the vehicle. The deliverable is the scientist that comes out the other end."

I encourage grad student advisors (and grad students) to read this. All the pithy hot takes miss the point, this is a breath of fresh air.

To spice it up, would you consider doing something on painting minis? I’d watch that! Just a thought.

Precise kinetic parameters for thermal resetting of clumped isotope signatures in biogenic and abiogenic calcites Carbonate clumped isotope (∆47) thermometry is a powerful tool to reconstruct paleotemperatures. However, episodes of heating or cooling can alter ori…

Excited to share some new #clumped #isotope bond reordering results just published in EPSL and led by Nico Kueter & Nathan Looser @eth-eaps.bsky.social. Come for the high-precisino reordering kinetics, stay for the beautiful FTIR maps!

🔔🚨 New Publication Alert!

Research has shown that the Antarctic Ice Sheet is a climate tipping element.

We found: it’s not one — it’s many.

Caesium - Image Compressor Caesium is a free software developed for simplicity and effectiveness. Compress your pictures up to 90% without visible quality loss

I know this is the nerdiest answer ever, but in your situation I’d look into caesium (strong compression maintaining high-quality pictures) + plakar ptar (large tamper-proof archives with rapid access to individual files and web-based preview gui). Good luck!

I also love integrating Typst documents with the output of Python code, which is super easy using TOML import/export.

E.g., list dozens of taxons in a floating table, then collect all listed taxons in the caption, sort them alphabetically, replace the taxons in the table by numbers and list the numbers and corresponding taxons in the caption. That took 15 mn to get right, with zero prior Typst background.

I was like you a happy LaTeX user. I tried Typst for a proposal and found that I could do fairly complicated things in functions with very little effort, even as a newcomer, that would have been impossible (to me) using TeX macros.

Living on the edge: Response of Late Cretaceous rudist bivalves (Hippuritida) to hot and highly seasonal climate in the low-latitude Saiwan site, Oman Abstract. Earth's climate history serves as a natural laboratory for testing the effect of warm climates on the biosphere. The Cretaceous period featured a prolonged greenhouse climate characterized b...

Starting the week well with a new paper! 🧑‍🔬 Here we show remarkable evidence of rudist bivalves in the hot, Late Cretaceous (75 Ma) tropics mineralizing their shells at temperatures of over 40 degrees C, hotter than any mollusc living today.

⏰New paper⏰

Proud to be part of this work led by Alex Quizon & Sierra Petersen where we show that most snails (we tested) precipitate their shells in isotopic equilibrium with seawater, enabling climate reconstructions like the one published earlier this week.

An essay on wank | deadSimpleTech This captures well the uncomfortable, slightly disorienting feeling that wank creates when you're subjected to it, wherein you're expected to speak about and think about the statement as though it says what it facially does, but also not push too hard or at all, because challenging the factuality or other face-value elements of the statement is a personal attack on the person saying it and their identity. I'm sure we've all been in such situations, unfortunately, and we can all point to lots of situations where wank is prevalent in our current society.

Long but very good:

"An essay on wank"

It names and identifies one of my least favorite genre of posts – finally I have a proper term for it!

I'm sure I've been guilty of it too in the past, so it's useful for self-regulation, too.

Increasingly convinced the main damage cell phones have done to creativity isn't decreased attention spans or what not but the elimination of productive boredom. Inspiration comes from the mind filling the void inside. Hard to make art when you're constantly silencing the silence with "content."
