saw 3 tardigrade exoskeletons with a single egg inside, including this one in the timelapse above, anyone know much about this tactic?

Had a blast at Artisans Asylum open studios scoping tardigrades. Made some fun timelapse too with the ciliates in the sample providing the ‘scribbles’. Def attracted nerdy types with the tardigrades, but even people who didn’t know what they were were captivated by their cute little wiggles.

Nice to see artwork from my new scope finally on paper. Gearing up for Artisans Asylum open studios this Saturday 2-7pm. I’ll be selling plankton stickers and will have a live tardigrade station! #sciart #microscopy

Boston folk, Artisans Asylum fall open studios is next Saturday, 2-7pm. I will be setting up a live tardigrade station in my studio! :) Would love to see you there. tinyurl.com/FallIntoMaking #sciart #microscopy

I just love their pigment designs does anyone know about the function?

If anyone on here knows how to ID polychaete larva, I’d love to work with you on getting to the species level on these worms I always find in Boston harbor. I could provide a ton of photos, if I knew what to image for an ID. I know they are spionid but that’s it. #sciart #microscopy #plankton

anyone on here an expert on fluids?

For #fluorescencefriday I just thought these neurons in the lateral geniculate nucleus were pretty. #sciart #microscopy #confocal

Really loved this part of Plankton Performance at MIT museum. This part of Movement II: Charles river is done using timelapse and fluorescence microscopy. Note all the filamentous cyanobacteria. Big red blobs are rotifers with chlorophyll in their bellies swimming around. #sciart #experimentalvideo

Also anyone have an id on this mystery critter from the Charles river I followed during the performance?

Hope to do a lot more collabs with Senem. Also my friend who works at the museum gave us the cutest gifts afterward. MIT museum has a killer gift shop- and for my stuff it’s just a fantastic space. Copepod bigger than a human on that screen! #sciart

I’m a day late for #fluorescencefriday but I had a blast at MIT museum ‘performing’ with live improvised sound by Dr. Senem Pirler. Vid shows fluorescence microscopy of the Charles river, note all the cyanobacteria. #sciart #plankton

Last call for tickets for this unique concert! This is a big one for me so Boston folk, I’d love it if you could join. Video shows the trails of diatoms in timelapse. mitmuseum.mit.edu/programs/pla... #sciart

Plankton Performance, this Friday 7pm at MIT museum. I will be collaborating with plankton from the Charles river under my leicamicrosystems.bsky.social microscope, while Senem Pirler responds to their movements and behavior with sound. mitmuseum.mit.edu/programs/pla... #sciart

A rare green fluorescent flagellate, ‘swimming plant’, trails in timelapse under fluorescence microscopy. Anyone know what causes green fluorescence in marine critters? 99.9% of flagellates I find are red from chlorophyll. Sample collected from Boston harbor. #sciart #algae #plankton

Lovely vacation with my folks on Mt Desert Island in Maine. Amazing spot on the water, I brought a little scope and had a blast looking at sea life. Even the lichen next to the house had tardigrades! #sciart #microscopy

Also this unknown arthropod (I think) literally crawled out from under the coverslip! Made a beeline for my stage clips but then got confused and turned back. Never had anything like this happen before. I thought have looked at it but does anyone know what it is (sorry just have this vid)

Doesn’t this polychaete look a bit like Toothless? #sciart #zooplankton

Started my vacation with a family visit to my studio, looking at water from the harbor. My sister Brit is the one that crocheted me all the adorable critters (great for workshops too). And we found a polychaete that looked like toothless! Below. #microscopy #sciart
