Final result (better to do the rolling-ball background subtraction before merging, and merging using Max rather than blending)

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

I finally got my hands on a MRI! Didn't help my wrist but now I have some really cool image stacks to play with 🤩

I like this movie, but a friend of mine likes to complain about the obvious stitching artifacts. I'll try harder next time, Michael. Vimentin (orange) and ER (blue) in an overnight acquisition.

iPS cell-derived cardiac myocytes (heart muscle cells) typically beat about once per second, so I usually speed up the movies I post; otherwise, scrollers might miss the action. But every now and then, a cell looks like this in real time. #CellBiology

Attempt number seven at uploading this video of intermediate filaments in an enormous COS7 cell. I have a feeling the BlueSky compression will not do it any favors.

Happy #FluorescenceFriday. This beautiful video shows slice by slice section of a zebrafish embryo's head. The embryo is almost completely transparent, proving that zebrafish is an amazing model system for microscopy.

This week's #FluorescenceFriday, we'll be treated with one of the classical models of #devbio, the neural crest cells. Here is a beautiful video of neural crest cells with GFP-tagged focal adhesion kinase (🔵) and LifeAct-RFP (🟣) migrating on a Fibronectin matrix.

ATP has many roles: energy currency, hydrotrope, and *danger signal*
Immune cells are faster after ATP exposure, F-actin (cyan) goes to the rear for nitro boost!

During my postdoc, I looked at hundreds of images like this 🤩
These are two apical caulonemal cells from moss Physcomitrium patens stained with MDY64 (shown in shades of orange). The natural autofluorescence of chlorophyll is in cyan.

This image by MDI Bio Lab's Travis Carney is a #drosophila larval brain. Neural stem cells and neurons are marked, including axons that project into the brain. The flare in the center of each lobe is part of a learning and memory center in flies.
