Seldom do protists show up in public places (as man-made creations; plenty of them thrive happily unseen), especially those who reside where the sun don't shine: the hindgut of wood-eating termites and cockroaches.
This Mayorella 's (?) nucleus is smiling and wishing you a very happy day =) The auspicious pattern is formed by heterochromatin clumps. To the right of the nucleus is a contractile vacuole -- devoid of any emotion this time.
I may have mentioned a few times to never mess with amoebae. Let me reiterate how lucky we are to be a few orders of magnitude of size removed from those creatures.
Frontonia are a large, gluttonous species of ciliates, which makes them a wonderful, colourful, subject of microphotography. Despite the modest appearance of their mouth, they can swallow some impressively big prey -- the suture beneath the mouth can open to widen the engulfment.
I'll return to blogging by starting off with a stunningly boring micrograph. Here, you can see a narrow blob, with a blob attached, and a stem below.
A free-living cyanobacterium (above) lies next to its brethren from a distant past, now a chloroplast coiled up and trapped (for good) within a eukaryotic cell (bottom).
Here's a diatom (alga in a glass case), probably Cymbella sp. (apparently also called "rock snot"...), sitting atop a stalk of mucilage. These diatoms can sometimes be seen on rocks in creeks and streams as fuzzy brown stuff growing, comprised of large colonies.
I meant to throw these stockfish photos up during Science Online as compensation, but there wasn't exactly any downtime at that conference. At all. Shocking and entirely unexpected, I know.
Back from #scio13, an awesome conference on online science communication in Raleigh, NC. Fingers poised for MOAR blogging! For now, I'll drop some hints for the yet-unsolved Mystery Micrograph from a while ago.
Microbiologists might comprise the vast majority of people who get excited about sewage and other putrid-smelling places. A sample of activated sludge or a treatment pond make wonderful presents for bacteriologists and protistologists alike.
