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.

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.

Excuse the cluttered desk please!

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...)

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.
