Hijacking of the cell by its uninvited invaders is one of the coolest things in biology. Not only do these parasites leech off its food, they also ride along with the cell machinery itself — modifying parts of it for their own benefit, of course...
While we transition from paleontology back to protistology, let's make a short stop along the way. A stop in downtown Chicago, of all places. You know, the ideal place for finding living critters and fossils, right?...
Yes, Indiana has coral reefs. More on that in a bit. A couple days ago I entered a trilobite doodling spree, and have come up with a sort of technique for drawing them.
Mystery Micrograph revival time! Y'all failed the previous one, but fear not -- there are plenty more to come! The subject of the last puzzle, shown below, is the surface of a testate amoeba -- namely, the organic test of Arcella spp...
Out in nature, you may notice that critters often like to be on top of one another, or inside one another. Of course, I'm talking about endo- and ectosymbioses (inside and on the surface, respectively)...
Giardia is a cute flagellate with two nuclei, eight flowing flagella and an impressive sucker plate that makes it look rather like a catfish. Their elegant swimming patterns are reminiscent of one as well...
One night, when I was definitely completely sober in every way possible (of course!), it struck me that while both the European and Chinese zodiacs (ones I'm familiar with) display a nice variety of animals with and without backbones (I happen to be spineless according to the European one, and scaly and flame-breathing according to the Chinese version), somehow the ancients have missed out on a very major and obvious group -- the protists...
A quickie post to assure y'all I'm still around. Got a few proper posts coming soon! Remember our testate amoeba friends, the arcellinids? Here is a pair of Arcella s (Arcellae?) in the midst of division...
Bleary-eyed and staggering, many of us partake in a morning coffee ritual before mustering the courage to face the daily workload. In addition to psychoactive chemicals (drugs, anyone?)...
For me, the second more relaxing activity after microscopy is vector art. And then regular art. (This excludes non-activities, such as napping in the sun, and staring at life passing by...
