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.

Team of #HZDR & #CNRS explains how #diatoms interact with #uranium. As algae can be the starting point for the accumulation of harmful substances in the food chain, the results help to better understand the impact of the release of uranium on natural cycles.

🚨 ALERT: Scientists discover microscopic ocean drama! 🤯🔬 After 60 years of intense observation, it turns out #diatoms and #dinoflagellates have been battling for biomass supremacy in the North Atlantic. 🌊 Clearly, Mother Nature is more compelling than any Netflix series. 🎬🍿

Study resolves diatom tree of life, could offer clues to Earth's puzzle
Research finds #diatoms evolved slowly for 100 million years and then experienced an evolutionary burst of #speciation 170 million years ago.

"Such deposits are like a time capsule containing valuable information about past ecosystems and the inhabiting biological communities, their population development and genetic changes"

#Diatom phytochromes integrate the underwater light spectrum to sense depth: Carole Duchêne et al. https://www.nature.com/articles/s41586-024-08301-3

"These photoreceptors enable them to detect changes in the light spectrum in the water column, thereby providing information regarding their vertical position within it."
