A diatom, probably Guinarida species (in the middle).

Brunsviken, a freshwater lake in Stockholm, 3rd of May 2025. 600x magnification.

I am still setting up, searching for relatable proper microflora atlases and learning to add a scale bar, etc. But I drop some photos in the meanwhile. If you have recommendations on how to solve these issues, or on any other improvements, drop them in the comments below!

But first, this thing hadn't been used for years, so I had to clean it a bit. Maybe it was also just an excuse to understand how this thing works :)

It's an inverted design and has two optical paths, one for the binoculars and one for the camera.

Side view of the microscope with one of the covers open. The inside shows several mirrors and lenses redirecting the light to the different output ports.
Schematic drawing of the microscope. The light comes from the condenser at the top, moves down through the specimen, then the objective. From there it's split at a prism in two light paths. The upper one is redirected to the top where the binocular sits, the lower one is directed to a second output at the front of the device where a DSLR can be mounted.

Thought I'd do a quick re-#introduction since I just moved under this beautiful rock. Let's see what life is like in a smaller place.

I feel right at home, because I'm mostly tooting and boosting about #inaturalist #entomology #microscopy #wildlife #mothing
But that's very on-and-off, call it seasonal maybe.
I also have a long running project trying to CNC-automate my #microscope. Image processing (stacking/stitching) is in place.

I might also comment or toot about a bazillion other things, anything from computer security to tree felling.

I live in Norway, where we build routers at Celerway.

On August 13 President #Biden toured #cancer #research #facilities at Tulane University in New Orleans and deemed the developments "incredible."

Why it matters:
⭐️He announced about $150 million in federal awards during the visit as part of his #cancer "#moonshot" initiative that aims to ❇️cut the cancer death rate in half by 2047. ❇️

The big picture:

"We are the land of possibilities," the president said, adding that the funding will help get new tools into operating rooms.

Nearly 2 million Americans are diagnosed with solid tumor cancers each year, and #surgical #removal is often the first step in their treatment, the White House said.

Tulane is getting $22.9 million to invent 💥new imaging systems that will allow surgeons to see in real time if they removed all cancer cells while their patients are still under anesthesia.
It currently can take days to weeks for doctors to know if all of a tumor has been removed, according to J. Quincy Brown, the lead researcher on Tulane's project called MAGIC-SCAN.
💥The goal is to get that down to 10 minutes within the next five years, he said.

Zoom out:
Seven other teams are working on additional developments geared at making #tumor-#removal #surgeries more successful.

The awardees are
Dartmouth College,
Johns Hopkins University,
Rice University,
University of California in San Francisco,
University of Illinois Urbana-Champaign,
University of Washington and
Cision Vision in California.

Their projects include inventing a #new #microscope and creating #new #imaging #systems to visualize blood vessels and nerves

3/x Lunchtime #microscope break!

If you enjoy zoomed in #LEGO you might also be interested in some #photos of a zoomed in kevlar blanket that flew to #space in the cargo-bay of Spaceshuttle Discovery (last on STS-82, a Hubble repair mission).

The material is more reflective than it appears so very high magnification photos are difficult with my setup (an old microscope illuminated by overhead light and a smartphone hovering over it for photos).

Magnifications of 30x, 60x and 100x

The setup. This is a kevlar and kapton (something that looks like very expensive aluminum foil) composite. The kapton is at the back (not visible) where it acts as an insulating layer. The kevlar is on the exposed side to protect stuff from micro-meteorites and clumsy astronauts. It had SCRAP stamped on it.
30x magnification
60x magnification
100x magnification. Due to the thickness of the material it's not possible to get the full vertical space in focus.

1/x Have you ever wondered how #LEGO degrades when it's buried in a sandy #Danish garden for about 30 years?

I did. Here's the answer. I took photos with a #microscope (30x magnification) of an old brick (1x2 slope) found in our garden, and a newish brick found on an elfish castle.

The photos (smartphone camera held above the oculair) answer the question of what it looks like.

More info in the ALT tags.

And back to work 🙂

The two bricks. Circled is the area photographed via the microscope. The new brick is never washed. The old brick was washed with soap after found in the garden. The old one has some clear scratches. Those are not the one visible in the microscope. In there much smaller dents and filled up damage is visible.
The new brick. Smooth surface, no discoloration and rounded edges. The little white spots are dust laying on top of the brick. The photo distorts the color into a hue. In real life it's a solid red.
The old brick. Discoloration is real. Scratches of different depth. There's a variety of dents and holes with missing material. Edges are less round than in the new one but still rather ok. Clutchpower is also perfectly ok: the brick functions as a new one.
The setup. Old Dutch school microscope.
