I started a 7x5 challenge. I want to play more of the games we own and explore some of the possibilities hiding in these boxes. Hopefully I didn't bite off more than I can chew.

@skyfaller @nancywisser I wonder how the Academy of Natural Sciences of #Philadelphia came to be the publisher of a book about #Montana’s #diatoms. Where are all the Montanan academic presses?

They oughta be ashamed that they let some east coast press publish the definitive work about their state’s diatoms, written by the curator of the Montana Diatom Collection! Is there no state pride in Big Sky Country??

When I ordered "Fishes of the Wissahickon" from Drexel, they accidentally sent me "Diatoms of Montana and Western North America: Catalog and Atlas of Species in the Montana Diatoms Collection" by Loren Bahls instead. They're sending the correct book, but they don't want me to return "Diatoms of Montana".

What should I do with "Diatoms of Montana"? It's two volumes, pretty thick. If I lived in Montana I'd probably hang on to it, but I'm not that into diatoms or Montana.

Protein shell discovery reveals how #diatoms capture CO₂ so effectively https://phys.org/news/2024-10-protein-shell-discovery-reveals-diatoms.html

"diatom pyrenoids are encased in a lattice-like protein shell... not only gives the pyrenoid its shape, but it helps create a high CO2 concentration in this compartment. This enables Rubisco to efficiently fix CO2"

Protein shell discovery reveals how #diatoms capture #CO₂ so effectively
Using #photosynthesis, they absorb large amounts of #CO2 and convert it into nutrients that feed much of #ocean life. Researchers discovered a protein shell that plays a key role in the diatoms' CO2 fixation. Using cutting-edge imaging technologies such as cryo-electron tomography, researchers were able to reveal molecular architecture of so-called #PyShell protein sheath and decipher its function.
