AI Use Appears to Have a "Boiling Frog" Effect on Human Cognition, New Study Warns A new study claims to offer the first causal link between AI dependency and cognitive erosion. Researchers warn of long-term implications.

NEW: A new pre-print study offers the first causal evidence that outsourcing reasoning tasks to AI can rapidly erode users' independent performance AND their will to persist despite difficulty.

"People’s persistence drops... they’re also not willing to try without AI.”

This whole post by @couchmicroscopy.bsky.social💯!!! When I found out she used to come to the island i work at, i wondered why (affected by others, assumed she joined her husband working in Arecibo, but no, she kept coming long after he was not), but then again, i am here, too, in a symbiosis oasis.

MidSEC 2026

To my #protistsonsky and 🦑friends, I am co-organizing this meeting: "Midwater Science and Engineering Community" (MidSEC) Conference. If you work with or are interested in midwater protists (radiolaria, foram, deep water coccolithophores, etc) (or animals) it may be of interest to you!

Rare microbial relict sheds light on an ancient eukaryotic supergroup - Nature The discovery of an unusual protist named Solarion arienae, which has a mitochondrial genome with some intriguing features, provides insight into the early radiation of eukaryotic groups.

I'm personally keen to not introduce new names when the original work/are valid. Marek's paper (and Disparia) was out as a preprint since May and the question could go both ways. Solarion + Meteora as Caelestes work well imo. But, I'm fan of Promethea and I think both papers are awesome! One love 😁

When I've first seen the transformation under a microscope, the integration and disappearance of the flagellum, back then we had no idea what group of protists it could be, if it's even a eukaryote, it blew my mind. One can be seen in the Supplemental video 3. It keeps blowing my mind.

Thank you! Well, but.. it IS a tiny ball, forming extrusome tentacles, when it is NOT a flagellate!

✨ A study in nature.com from our Faculty at @unikarlova.cuni.cz reveals Solarion arienae, a rare #protist forming a newly identified eukaryotic supersroup Disparia. A unique window into early #eukaryotic cell #evolution. 🌍🔬👏

Is it a flagellate? A tiny ball with tentacles? Contamination in my ciliate culture? NEW SUPERGROUP OF EUKARYOTES? Yes to all 4! Meet Solarion - just out in #Nature doi.org/10.1038/s415... Huge congrats to Marek Valt, Cepicka Lab & the star team! Very happy to be part of this project. #ProtistsOnSky
