Die Oberfläche einer "alten" Münze bei 25facher Vergrößerung. Es handelt sich um eine 10-Kč-Münze (Tschechische Kronen) mit dem Prägejahr 2009, die aus unbekannten Gründen für eine unbekannte Zeit auf einem unbefestigtem Parkplatz in unmittelbarer Nähe zur Nordküste der Insel Rügen verbrachte, bevor ich sie im Oktober 2024 gefunden habe. Die Wetterbedingungen wie Wind und Regen haben wahrscheinlich ebenso zum Zustand der fortgeschrittenen Alterung beigetragen wie das gelegentliche Überfahrenwerden durch Autos. Viele Details wie das hier erkennbare Währungssymbol und das Prägejahr auf der Rückseite waren nur unter dem Mikroskop sicher erkennbar.
The surface of an "old" coin at 25x magnification. It is a 10 Kč coin (Czech koruna) minted in 2009, which for unknown reasons spent an unknown amount of time on an unmade parking ground in close proximity to the Northern coast of the Isle of Rügen, Germany, before I found it in October 2024. The weather conditions like wind and rain likely contributed to the condition of advanced aging as being occasionally overrun by a car. Many details like the currency symbol shown here or the minting year were only clearly visible under the microscope.
Die Oberfläche des Endes (Epiphyse) eines Vogelknochens unbekannter Vogelart, gefunden an einem Strand im Norden der Insel Rügen, bei 25facher Vergrößerung. Aufgrund der langen Wirkung von Wasser und Sonne ist der Knochen vollständig mazeriert.
The surface of the end (epiphysis) of a bird bone of unknown bird species, found at a beach in the North of the Isle of Rügen, at 25x magnification. Due to the prolonged effects of water and sun, the bone is fully macerated.

Found these guys swimming in a droplet of ocean water. There must have been a billion of them! This is at 1000x magnification, so you can imagine how amazingly tiny they are.

A filament of an unidentified organism. This filament, in spite of appearing as an empty skeleton, is motile. Magnified 400x. Collected from the yellow mud at the Weep Site, near Drawbridge, in the Don Edwards San Francisco Bay National Wildlife Reserve.
Because I haven't had a chance lately to sit down and take some new microscopy photos, I've uploaded a few scraps here from old sessions.
There are "fuzzy" heterogenous deposits in capillary walls located in bottom-center and bottom-right of micrograph. Mesangial & para-mesangial regions are expanded due to deposition of this substance

2003 electron micrographs of an indian shell bead, taken while I was at Humboldt State University.
(Sadly, I don't have any further notes on the bead or it's origins handy...)
