The bad bug hiding in the bush 🪲

Antibiotic-resistant Acinetobacter baumannii hiding in a flower-like bed of crystallized buffer, exposed by the probing electrons of TEM.

🎉 Good news everyone !

The #CIME @EPFL electron microscopy image contest now requires participants to submit their work under a #CreativeCommons license. 🔬

 https://www.epfl.ch/research/facilities/cime/index-html/image-gallery/image-of-the-moment/

Result: These images can now circulate freely including here on the #fediverse!

So I’ll take the opportunity to share a few here. ✨

Whole-mouse imaging the hard way: Clearing, then slicing + block-face imaging with beam-scan / sensor scan-line synchronization and continuous stage movement in an oblique imaging setup (ViSOR).
This time, they scaled it up to whole-mouse and used pre-cleared mouse bodies (ARCHmap-blockface-ViSOR):

Here's a #MicroscopyMonday segmentation of some neurons from the optic lobe, or visual processing area of the #Drosophila fruit fly's brain. The #connectome for the full optic lobe was released in 2024 by #HHMIJanelia, Google, and the University of Cambridge, with support from the Wellcome Trust.
This segmentation of #MicroscopyMonday data reconstructs neurons of the "MANC", or male adult nerve cord, from the #Drosophila fruit fly. The nerve cord is like a spinal cord and connects the brain and muscles. #HHMIJanelia, Google, and the University of Cambridge released this work in 2023.
A use of #MicroscopyMonday data is making segmentations. Here's one, of #Drosophila protocerebral bridge and nodulus neurons, from the 2020 Hemibrain by #HHMIJanelia and Google. Michał Januszewski and Viren Jain's team made an initial segmentation with #AI flood-fill algorithms...

Ya boi is back with more microscope photos :3

Here are a few pics of a cool looking filamentous algae I found looking at more bog water under the microscope. I don't know too much about algae species (yet!) so I can't say much in terms of identification for this specimen, but it's certainly pretty to look at!

#MicroscopyMonday – No this is NOT an aerial view of the Grand Canyon.

This is a scanning electron microscopy image of the cranial sutures in the rat skull. 🔬💀🐀 These are fibrous joints where the bones of the skull interdigitate, allowing for flexibility and growth during infancy and early childhood before fusing in adulthood.

Happy #MicroscopyMonday!
Here is a kymograph of a cell crawling into a microchannel. Each horizontal row of pixels represents a line drawn from outside (green) through a channel (purple) at 5 second timepoints. ~1/2 way down (20 min) a cell fully enters the channel and takes off!
