Anything related to things that are too small to see them with the eye, and the tools used to observe them.

This space is quite general in scope - microscopes, microbiology, small component electronics, questions about buying optical components, etc.

Tarantula (Acanthoscurria geniculata) embryo showing expression of genes that pattern the legs and body wall. Right side has curved abdomen, 4 walking legs, and 1 pedipalp (head accidentally removed). Left side has curved abdomen and 1 walking leg (the rest accidentally removed).

The pink/white stripes are where the gene "odd-skipped" is expressed, which marks where the leg joints will form.

Are image uploads not allowed here? Only URLs? Thanks! Hoping this community grows and flourishes! :)

The school year just ended but I wanted to show off what my class was able to accomplish with some cheap high school microscopes. The images below are under-leaf impressions of diocot and monocot plants which show the stomata used to control water evaporation. To avoid the preparation of slicing leaves themselves we painted a thin layer of nail polish on the underside. Peeling this dry layer off results in a mold of the leaf itself which can then be attached to a blank slide with cellophane tape.

Dicot @400x

Monocot @400x

I have to admit, not my most successful attempt at the "apply violence until the die is visible" method of decapping ever. The silver stuff to the right is the broken off silicon.

I put a drop of liquid from my lotus flower's vase under the microscope and noticed a lot of bdelloid rotifers, so I decided to record one at 400x magnification.

I also used this opportunity to upload a video to a PeerTube instance. It is actually a bit of work to find an appropriate instance willing to register new users, as many of them accept a narrow range of topics and 'microscopy videos' is usually not one of them.
