Just posting to host this, so I can get an ID on these bugs.
If you know what this is, please give me a clue.
Scale bar is 50 micrometers

Le pédoncule peut s'accrocher aux rochers, aux plantes ou toute autre surface immergée. Quand les cellules de la diatomée se divisent, lors de la multiplication végétative, le pédoncule se divise aussi, formant parfois des masses de pseudopodes branchés. La nuisance de ces formations n'est pas liée à la cellule elle-même, mais à leur production massive de pédoncules extracellulaires. Les substances extracellulaires polymériques (EPS), qui forment les pédoncules sont constituées initialement de polysaccharides et de protéines, formant une structure complexe, multi-couches qui résiste à la dégradation naturelle.
40x 0.65NA objective. HD video focus stacked.
Tried an oblique light from the top, which really doesn't do the subject any favors
Microscope at IITA Bioscience Center for magnification of slide and chromosome counts. Photo by IITA.
This model microscope does not win many points on ergonomics; not with the focus knob at the back. The reason for placing it there, is that the mechanism that raises and lowers the objectives is rather chunky. By turning the focus knob, a linear actuator lifts or lowers the objective carousel. Of course, it is possible to raise them too high and crush the objective into the table. If you have never cracked a slide, you never have used a microscope! (After I wired the microscope up, though, the carousel gets stuck just below the maximum height...)
The 96-wells plate was the first thing I built for this MOC. It set the scale for the whole project... I know, I said it is 1:1, but actually more like 9:10 - when measuring the microplate. The cross table came next. The size of the plate determined the required swing out, that, in turn, for the size of the stage, and so on. I was quite pleased to come up with a trick to put two wheels above each other, the x-axis and y-axis controls, so to speak.
In my research, which focuses on alternatives to antibiotics in the face of growing anti-microbial resistance (AMR), I am struck by how tiny agents can cause such global upset, with AMR predicted to kill 10 million a year by 2050, eclipsing both cancer and pandemics like Covid-19. Can we prevent such a bleak prediction from becoming a reality?
Science is a quest to remove ambiguity through experimentation and observation, nonetheless, we cannot always trust our eye. Without augmentation, our human abilities fail to sense scales of the very large or small. However, telescopy and microscopy address this by bending light to the will of the operator and thus bring into focus worlds otherwise unseen.
In line with the theme of ‘2020 Vision’, this photo captures the multiple refractions that take place to make the invisible visible, bringing clarity to the obscure: the microscope’s eyepiece, my glasses and my eye. Indeed, in this photo, shot on a Fujifilm HS30EXR in the microbiology research laboratory, the camera itself provides a fourth lens: a lens within a lens within a lens within a lens, highlighting the power of a simple technology to observe bacterial behaviour and possibly alter the course of the future.

Biologist is something that defines me. From an early age I had an enormous curiosity. I wanted to know why things worked they way they did. Life fascinates me. Biology was my favorite subject in school. I read tons of books about life and how biological processes worked. Now I study life science, and I love research.
This is one of my work benches. Microscope, samples, sample list, empty petri dishes and tons of other junk, most of which isnt mine.
Mysteries of life, watch out, because Im here to unravel you!
Four shots like this one, always the opaque part of the microscope slide barely broke.
Interesting, the rough surface let the glass more resistant?
Usually I would think the opposite.
