So. My partner and I have a holiday tradition where we go to at least one, sometimes multiple, bookstores and buy each other piles of books. It's a fun once-a-year splurge, and so we both usually end up with a great array of new and secondhand books to enjoy throughout the year. We ended up delaying things until Powell's had their Friends and Family sale, and hit up a couple of their locations along with a few other local bookstores. I got some pretty awesome stuff this year, but this has to be my best find:

It's exactly the kind of thing one would use to bait a trap for me (along with assorted cheese and warm, cozy wool socks). I collect field guides, and this one is delightfully niche. I almost put it back after reading the title because I've been trying to cut back a little on adding to my pretty, artistic vintage field guides in favor of up to date books for research. But then I looked inside:
Tumblr media
Look at that. This isn't just discussing the general fur patterns and textures of mammal hairs. It's a bunch of microscopic photos of each type of hair of each species listed, showing unique cuticle textures that can be used to identify an animal based on a single hair. I mean, this is one of those areas of nature identification I knew existed but had just never really delved into myself.
Oh, and it's been out of print for ages and is basically impossible to find online. The chances of me finding this again were pretty slim. And for fourteen bucks less 30%? SOLD.
Tumblr media
I really appreciate how several canids were included, like the gray wolf, coyote, coydog, German shepherd, and Labrador retriever (really cool to see how the textures of the two domesticated breeds differed!) I can also see where this would be really useful if you have some sort of pack-hunting canids going after livestock and you manage to find a bit of hair; I wonder how many wild species would be exonerated in cases where it's actually domestic or feral dogs causing trouble?
Tumblr media
I'm also really intrigued by this note on the porcupine's page. Is it caution over issues identifying porcupine hairs, or did Moore et. al. write an entire study (or book) on reasons to exercise caution when collecting and examining a porcupine's hairs? (Probably best to save the examination for hairs that are not still attached to said porcupine.)
Anyway. This is a really cool addition to the field guide collection that's got me wanting to break out my microscope once I have the book manuscript done and have a little more time.

1 & 2. maybe some kind of hair styling cap? wig holder? last time i went, someone had unwrapped it.
3. delightful octopus jug!
4. there were about 6 other microscopes. one had migrated to the dishes section.
5. surprisingly heavy bird-thing for only 99 cents! a steal!
6. creepy clown caterpillar bookend. it was still there the last time i went.
7. another bird-thing. looks handmade? not sure of its purpose.

Atomic force microscopy, or AFM, is a widely used technique that can quantitatively map material surfaces in three dimensions, but its accuracy is limited by the size of the microscope's probe. A new AI technique overcomes this limitation and allows microscopes to resolve material features smaller than the probe's tip. The deep learning algorithm developed by researchers at the University of Illinois Urbana-Champaign is trained to remove the effects of the probe's width from AFM microscope images. As reported in the journal Nano Letters, the algorithm surpasses other methods in giving the first true three-dimensional surface profiles at resolutions below the width of the microscope probe tip.

Science Saturday
Here are a few pages and plates from A Practical Treatise on the Use of the Microscope by notable English microscopist and histologist John Quekett (1815-1861), published in London by Hippolyte Bailliere in 1848. Bailliere was a prominent science and medical publisher whose imprint has survived as a medical imprint of the Elsevier publishing group. 
A classic in its field, the book includes nine engraved and lithographed plates and 241 wood engravings. It opens with a 46-page history of the microscope that remains definitive to this day. It then describes a number of microscopes and instruments with exquisite illustrations and detailed descriptions of the rationale and function for each instrument. Part two of the treatise provides detailed instructions on the use of the microscope and ends by detailing various methods for preparing specimens for microscopic examination.
John Quekett was conservator of the Hunterian Museum in Glasgow, a long-time secretary of the Microscopical Society and then its president, and he was a fellow of the Linnean Society and the Royal Society. His Practical Treatise was enormously influential among professionals and amateurs, and even Prince Albert came to him for instruction. His legacy is commemorated by the Quekett Microscopical Club, established in 1865.

Waterfleas carrying eggs
A Striking Short Film Documents the Otherworldly Organisms Living Just Beneath the Water’s Surface
With the aid of multiple microscopes, filmmaker and photographer Jan van IJken (previously) unveils the otherwise imperceptible maneuvers and bodily transformations of plankton. He focuses on a diverse array of underwater organisms, which all fall under the same taxonomy because of their inability to swim against the tides and are crucial to life on Earth, providing half of all oxygen through photosynthesis. Set against black backdrops, the marine drifters appear otherworldly in shape and color, and the filmmaker documents water flea eggs visible through translucent membranes, the spiked fringe of cyanobacteria, and the minuscule movements of various creatures as they wriggle across the screen.

UNISTAR 76mm Eyepiece and Moon Filter's Astronomical Reflecting Telescope
The UNISTAR 76mm Eyepiece and Moon Filter's Astronomical Reflecting Telescope WT76700 with Adjustable Tripod is a great entry-level telescope for beginners looking to explore the universe. With its powerful 76mm aperture and adjustable tripod, this telescope offers an exceptional viewing experience for amateur astronomers.
The telescope comes with a 76mm aperture, which is the diameter of the lens that gathers light from distant objects. This aperture size is perfect for viewing the moon, planets, and other celestial objects. The telescope also comes with a 700mm focal length, which is the distance from the lens to the point where the light is focused. This allows for sharp and clear images of distant objects.
One of the most unique features of the UNISTAR 76mm Eyepiece and Moon Filter's Astronomical Reflecting Telescope is the included moon filter. The moon filter is designed to reduce the glare of the moon, making it easier to observe the surface details of the moon. This filter is particularly useful during full moon phases when the moon is brightest.... for more
