I’m excited about my new website redesign! Check it out here: jessholz.com (ignore the text in the link preview I’m having trouble with cache-ing). Stay tuned, I’ll be updating the archive section with tons of plankton videos this month. #sciart

My good friend Kricket is deeply dedicated to studying the organism Stentor. Despite chronic illness and limited resources, she drives hours to the lab whenever she can. She’s been invited back to MBL this summer- please consider helping fund her stay! gofund.me/86b6b2f11 #plankton #microscopy

This amoeba from a Charles river culture featured in my solo exhibition that just came down- it started eating a dying flagellate- but the flagellate actually jumped out of its mouth! I’ve never seen that before. The amoeba did catch up with it and eat it tho. #sciart #microscopy #plankton

FINAL WEEK for Plankton Paintings: Footprints of the Invisible at Harvard Ed Portal. Next thursday is the last day to see it, it’s been a great run! I’ve really enjoyed bringing local plankton to center stage, and had some wonderful conversations. #sciart #microscopy

For #fluorescencefriday I present boring brown ‘junk’, debris, marine snow- consisting of decaying organisms and plant matter, that become colorful galaxies under fluorescence. I always wonder about the histories of living organisms present in these debris. Sample from the Charles river #sciart

Anyone know what the coiled structure is in these fluorescence photos? The coil seems to be only visible if the tissue is destroyed. 200-400x magnification, autofluorecence of a sample collected from punching through ice in a shallow part of the Charles river, Boston. #sciart #microscopy

Thanks everyone for coming to the opening of Plankton Paintings: Footprints of the Invisible. Had great turnout and the artist talk went well. My mom, sister, and friend from Milwaukee even flew out. Super special to share this with everyone. #sciart

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

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

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

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

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

I’ll be ‘performing’ with lively plankton from the Charles river at MIT museum Sept 12th, 7pm. Composer Senem Pirler will respond to the plankton movements with sound. Would love to see you there! #sciart #microscopy

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

I’m excited to announce Plankton Painting as a live audiovisual event/concert, in collaboration with Dr. Senem Pirler who will respond to the rhythms, textures, and motion of these lively organisms through sound. Boston folk, I’d love to see you there! mitmuseum.mit.edu/programs/pla... #sciart

Plankton painting at MIT museum was a blast! I’m stoked that 80 ppl came, the auditorium was almost full. See paintings from today at: flickr.com/PlanktonPainting Bosmina bloom in the Charles river right now, made things interesting. #sciart #microscopy

Boston folk, I’ll be doing a plankton painting workshop at MIT museum next weekend July 12th 11-12:30pm. Come see plankton from the harbor and the Charles, and print out your timelapse creation. There will be plankton stickers! #sciart #microscopy

Excited about these insect eye prepared slides I just got. I’ve always been super fascinated by insect eyes, starting in 2007 with my first installation ‘Eye art with corpses’, insect eyes made out of cast lenses surveying a scene of death and destruction below (crushed bugs). #sciart #microscopy

Slime mold cytoplasmic streaming. Physarium Polycephalum is a multinucleate giant single cell! Super new to slime molds but I’m hooked. Fist 20 secs sped up but the rest is not, the streaming is just -super- fast. Watch for flow reversals. #sciart #microscopy

1 more kids plankton painting workshop under my belt. Despite the screen they just loved looking through the eyepiece, to the point where they were arguing who got to go on it next. Neighborhood block party will feature an exhibition of their prints! #microscopy #plankton

Was going to rest today but got distracted watching decomposition under the microscope. The bosmina from Chandler pond were starting to decompose, so I did timelapse of bacteria trails (and occasional ciliates). Really quite haunting watching the bacteria start to take over. #sciart #microscopy

Jess Holz @jessholz.bsky.social · 11/05/2025

First plankton painting workshop at Artisans Asylum went great! I hope to do many more. Everyone got time to scope and left with a print. 4th pic/painting reminds me of constellations. Anyone looking for educational art/science workshops in the northeast hit me up. #microscopy #timelapse #sciart

3 kids microscopy workshops in a row last week- whew! Still tired. But really cool getting to introduce them. #plankton #sciart

omg. my sis crocheted a bunch of plankton (etc) including a copepod! I’ve decided the sombrero worm and copepod are friends- what should I name them? Between this and Paul’s cartoons this week I’m in nerd heaven. #sciart #microscopy

Jess Holz @jessholz.bsky.social · 26/04/2025

Big plankton poster is printed, it was labor of love. I wanted something with the major groups and stuff we see a lot that I can point to during workshops. The zooplankton cartoons make great coloring pages too! #plankton #sciart #microscopy

Jess Holz @jessholz.bsky.social · 24/04/2025

Yessss. Zooplankton cartoons! :) Many thanks Paul, @phyrexianmetamour.bsky.social for these amazing critter cartoons in the style of pokemon. Rotifer, ciliate, cladoceran & copepod- loving the 'speed' of the copepod, the 'ear' motion of the rotifer, etc. These bring me joy. #microscopy #sciart

Super weird debris covered thing ‘walking’ on a diatom from the charles river, with another diatom attached to it, along for the ride. For the life of me could not make out what it was. #sciart #microscopy #plankton

More timelapse plankton from the Charles river, first pic is w/ phase contrast. Heavy with Synura trails. I never noticed before but the Synura have this little green dot in their flagella under fluorescence, super cool. #sciart #microscopy
