A colored scanning electron micrograph of fruiting bodies of the fungus Aspergillus fumigatus. The round structures (conidia) are covered in tiny spores, about to be released into the air. A. fumigatus grows in household dust and decaying vegetable matter. Although harmless to healthy people, the fungus can cause complications in people with respiratory complaints or weakened immune systems. Inhalation of the spores may lead to infection of the lungs and bronchi, which can be fatal in some cases.

Lily Orchard recently started using the term tardigrade as an insult because she would really like to call her detractors a different word and tardigrade sort of sounds similar, I guess. This has inspired me put together a little educational aid:

And just in case you need a little more help spotting the difference, here's a higher res image:

False-colour scanning electron micrograph (SEM) of human nerve cells growing on the surface of an integrated circuit (silicon chip). The picture was taken in 1985 in the course of research into biohybrid circuits, & demonstrates how much smaller organic circuits are than man-made ones. Biohybrid circuits are possible electronic devices of the future that would combine organic & inorganic components.

The neurons grow on a Motorola 16000 chip, which was in use on the first Apples (pre-Macintosh) in early 80s, and e.g. on Meade telescopes up until late 90s.

I can't credit the researcher / institute on this, but there's more photographs from the same set here — I figure the band must've been flicking through the same pics back then, and any of these could've as well ended up the cover of Selfless in an alternate timeline: https://www.sciencephoto.com/contributor/syp/

Rob Kesseler is a visual artist and Emeritus Professor of Arts, Design & Science at Central Saint Martins, London. For the past twenty years he has worked with botanical scientists and molecular biologists around the world to explore the living world at a microscopic level. Using a range of complex microscopy processes he creates multi-frame composite images of plant organs.

Using scanning electron microscopy and a mix of microscopic, scientific, digital, and manual processes, artist Rob Kesseler develops coloured micrographs of the intricate patterns within pollen and seed grains, plant cells, and leaf structures. The photographs feature specifics of cellular composition that are undetectable without magnification.

Kesseler tells that as a child, his father gifted him a microscope, marking a pivotal moment in his creative career. “What the microscope gave me was an unprecedented view of nature, a second vision,” he writes, “and awareness that there existed another world of forms, colours and patterns beyond what I could normally see.” The artist says his use of color is inspired by the time he spends researching and observing, and that just like nature, he employs it to attract attention.

Dragonfly head. Colored scanning electron micrograph (SEM). Dragonflies belong to the scientific order Odonata, meaning toothed ones, because of their powerful serrated jaws. Dragonfly jaws can open as wide as their entire head, allowing them to eat large prey. When they hunt, the large compound eyes of a dragonfly allow it to sort its visual field, like a grid. Keeping their prey in the same section of the grid helps with accuracy when intercepting something mid-flight.

this whole matter of trying to sell things is so boring and distasteful. can you put some very bad (or very good) pattern ideas/requests in my ask to take my mind off it? please and thank you. anon is on.

I do want to start kicking these collections out the door on a two-week schedule (/shill) so the more nonsense ideas milling around of my brain the better, for once. Some off the top of my head:

Dressing Table – High Femme/Old Queen/Pickled Egg boudoir kitsch. Perfume bottles and roses in bell jars and Persian cat figurines and Art Nouveau vanity sets etc.

Viscera – Offal, just offal.

Diatoms, Animalcules, etc. These would especially be fun if I can figure out how to design round motifs (I've done one and it was just okay-looking and very hard) to mimic a microscope view.

Pollen grains – In a similar vein, my mother was a palynologist and I'd love to do a set of black-background motifs in the style of scanning electron micrographs.

Philately – I was a terrible stamp collector as a child (catastrophically disorganized from the word go), but I have a "postage stamp" border treatment I've been wanting to use.

Cryptids & Company – Mostly I just liked the title, "Putative Extinctions and 'Living Fossils'" is probably more the thing. Cryptids-as-such being culture-bound, I'd either want to limit myself to white-people cryptids (so like the loch ness monster and whom else? mothman?), which is it's own kind of weird, or solicit design/editorial assistance from someone qualified.

Turtle Island Food Science – American Thanksgiving is my problematic favourite holiday, and maybe that specific title is too dippy-white-Liberal to fly, but I do want to do a collection of Indigenous North American cultivated plants at some point.

Rune Stones – I was a teenage, twenty-something neopagan twenty years ago, it's true, but I still think this would be cute.

Things people actually buy at vendor markets – and it's just like, a knockoff Stanley mug, American junk food smuggled up from North Dakota, MLM leggings, essential oil jewellery and pickles

The origins of colour patterns in fossil insects revealed by maturation experiments

Published 20th September 2023

Researchers perform thermal maturation experiments on extant beetles to show how melanin-based monochromatic colour patterns are preserved in insect fossils.

The metabolic processes referred to above take place in the palisade cells and spongy mesophyll of the leaf (Figure 9.1). (...) Below the epidermis, the top layers of photosynthetic cells are called palisade cells; they are shaped like pillars that stand in parallel columns one to three layers deep (see Figure 9.1). (...) In the interior, below the palisade layers, is the spongy mesophyll, where the cells are very irregular in shape and are surrounded by large air spaces (see Figure 9.1). (...) Sun and shade leaves have contrasting biochemical and morphological characteristics:

Shade leaves increase light capture by having more total chlorophyll per reaction center, a higher ratio of chlorophyll b to chlorophyll a, and usually thinner laminae than sun leaves.

Sun leaves increase CO2 assimilation by having more rubisco and can dissipate excess light energy by having a large pool of xanthophyll-cycle components (see Chapter 7). Morphologically they have thicker leaves and a larger palisade layer than shade leaves (see Figure 9.1).

Lily, you're never going to make tardigrade an insult, this is never going to be a thing. People LOVE tardigrades! Just look at these little fellas go:

Besides, you saying that Twitter's full of tardigrades only makes the tardigrades sound bad.

The original image from Steve Gschmeissner/Science Photo Library is a colorized scanning electron micrograph of a tardigrade; microscopic sized Twitter/X.com paraphernalia added separately.

This tardigrade is seen through a colored scanning electron micrograph (SEM) Magnification: x1000. Water bears are small, water-dwelling, segmented micro-animals with eight legs that live in damp habitats such as moss or lichen 🦠

They are classed as extremophiles as they can survive dry conditions by changing into a desiccated state, in which they can remain for many years.
