after announcing that foreign students are being banned from Havard, Noem warns "this should be a warning to every other university to get your act together."

We're away from our lovely light and temperature controlled incubators @exoceanlab.bsky.social, but that doesn't mean we can't keep our plankton happy. @biosstation.bsky.social water baths to the rescue. If you've ever wondered what culturing for trace isotope systems looks like, it's this! #d11B
Dozens of small plastic flasks, each containing an individual foram sit in a temperature controlled water bath, under lights.

When your plankton sample smiles back at you 😊 💙. My colleague Maria Kavanaugh @lifewesea.bsky.social captured this on the IFCB today on board the @noaa.gov F/V Shimada where we are collecting samples in the N. Cali Current. Sometimes the ocean just sends you a little love. #Phytoplankton #Diatoms

I can feel the anxiety from aaaalllll the way across the pond. The anxiety here is palpable as well.

I’m not going to retweet that NOAA propaganda post about deep sea mining. Instead, I’ll tell you that I don’t know a single NOAA scientist who would promote deep sea mining in this way, because the available science we have does not justify exploitation of deep sea habitats for minerals.

Universities have documentation on awards status. Why take screenshots? downloads? Is any of this actually necessary? Grant intake info resides at institutional research offices. (admittedly, I saw this and instantly downloaded an excel spreadsheet of my grants, but am not sure this is necessary)

Led by Caitlin Reynolds, we (@jennfehrenbacher.bsky.social+ myself+others) have a paper out showing how #Globorotalia #foraminifera captured via #plankton tow can be successfully cultured using marine snow as food! A few persisted >2 months in the lab! 🧪 🌊 pubs.geoscienceworld.org/cushmanfound...
Fig. 4 caption in Reynolds et al. 2024: Globorotalia truncatulinoides (GT22) that grew an additional chamber after 34 days in the laboratory at the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center. The final chamber, panel A, is laboratory grown calcite as determined using measurements of the full length of the entire test (panel B). L1 is the first measured length of GT22 when brought to the laboratory and L2 is the final measurement after the foraminifera was morgued. The ΔL represents the growth of new calcite. In our study, we measured the length of 39 different chambers (F, F1, F2, and F3) on 13 different foraminifera (panel C) and determined 54 microns (mm) is the median length added to the foraminifera after each chamber has grown. In GT22, the ΔL was 52 mm, demonstrating laboratory grown calcite.Fig. 5 Caption in Reynolds et al. 2025: LA-ICP-MS profiles of 87Sr/88Sr ratio through the last 4 chambers in the final whorl of a Globorotalia menardii specimen (GM19) grown in 87Sr labeled seawater in the laboratory at the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center.

The tulips at the Wooden Shoe Tulip Farm in Woodburn, Oregon are in full bloom. It is truly a spectacular sight.

Hello! I'm Michael Warren and I write about birds/nature in early culture. The Cuckoo's Lea is out soon and with cuckoos now arriving this seemed like the perfect time for my debut post. I'll be posting lots on birds in our place-names, starting with cuckoos tomorrow! #naturewriting #birdsandplace

We have a little zoo here with 5 pets (few foster fails during COVID). Last summer, they were chillin' in my back yard & I got these great photos.... little pet photoshoot. The only one that wouldn't cooperate was Gus the Russian Blue (not pictured). #fosterfails #snowshoe #tabby #caturday

These are some very unhappy Globigerina bulloides #Forams. I have no idea what is going on here. Are they decalcifying? What are the vacuoles around the specimen? Until this field season, I had never observed this. These were also in the high CO2 "bad water". Has anyone observed this before?

There is debris in the spines here, typically a sign the forams is not doing well. They usually clear debris quickly. There was cytoplasm streaming on the spines, so it was definitely still alive. The shell is very thin.

I just found what I thought were deleted photos from our 2023 field season of #forams grown in "The Bad Water" (pCO2 = 800ppm). The forams weren't happy, but the symbionts were! Here, we captured the moment the organic template formed in the final chamber of Orbulina universa for #transcriptomics

We updated our products page to include info about pricing & product availability. Previous website info stated we did not yet have aluminum slides holders, but those are IN STOCK! www.micropaleoworks.com #micropalenotology #microslides #forams (better looking website coming soon).
Photo is of a box of micropaleontology slides of the 4-hole variety. 4-hole micropaleontology slide in an aluminum slide holder shown next to a blue pencil with the words MicroPaleoWorks - A Foraminarium Company inscribed on the pencil.This photograph shows 3 different micropaleontology slides in aluminum holders. There is a 24-hole slide, an assemblage slide with 60-grid background, and a 4-hole slide.

Posting past #NSFfunded #fieldwork photos. Here is a cultured Globigerina bulloides #foraminifera from our 2023 field season. We tried to capture the moment the organic membrane it templates calcite onto formed so we can identify shell matrix proteins #basicresearch #proteomics #biomin #NERCfunded
