Interested in science, natural history, preserving biodiversity. Restoring and protecting a 2-acre prairie remnant for 20+ years 😱 ... I have a lot of questions.

Weird word of the day: "kleptosquamy." The testate amoeba Awerintzewia cyclostoma steals scales from other amoeboid organisms to build its own shell. This one has robbed Quadrulella, Netzelia, various euglyphids, and even an Acanthocystis. Kleptosquamy! #amoebae #ProtistsOnSky #biology #nature

I have questions.
How does this even happen without destroying at least one crucial enzyme if not myriad enzymes in one fell swoop … mutation?

Implications for exobiology?
So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

If you are interested in a primary source for the beginning of next semester, may I recommend the earliest recorded indigenous description of Appalachia, translated by yours truly?
I'm working on a published version and would love any feedback you have as well.

Perhaps it’s just an indicator of my age, but I really feel Windows 11 should perform better than Windows 10, perhaps more stable and require fewer updates and rebooting while a person is trying to get some work done.
Also, restart should actually restart. Maybe young coders don’t know this?

Twitter accounts are based in Russia. BlueSky accounts are based in homes with, frankly, too many books, plants, obsolete cables, and pieces of rustic pottery, that could do with a bit of a tidying up, to be honest.

Okay … aside from often trying to read late at night and falling asleep, I’m also compelled to look stuff up to learn more when I’m reading. It’s going to require months to get through this book. 🫠

When consuming the world through a 6 inch piece glass and metal, it’s hard to discern what’s AI made.
Instead, actively participate in physical reality (sans device) and connect with the makers of the things you buy directly.
This deepens our bonds to each other and is often fun as hell.
