Sue...
Going through some low power microscope shots I took this spring I came across a couple of these "baby" leaf hoppers. Thought readers of this post might be interested in a closer look at these little critters. Kinda cute actually! They can be seen HERE.

Walt... is the 40X the same objective the previous owner used? I know nothing about savart plates, but I do have an Olympus DIC set-up. I know for certain that I can't assume that, for example, all 10X objectives will work with the 10X prism. Some don't work at all. Even within Olympus brand objecti...

Ken... Anyway the letter said that they made "a repair" as a courtesy I wouldn't put too much weight on that. I think there are a a few "form" answers and pieces of correspondence that these service departments use. Seems to me I recall scratching my head a little over the language on repair documen...

Ken... the sensor is most certainly covered by the warranty. Could it be that there was some very stubborn dirt or dust on the anti-aliasing filter that you thought was a sensor flaw, and what Canon did was a very thorough cleaning? (which would not be covered by a warranty).

Tom... I see the exact thing fairly regularly. I don't know the cause, but my guess is that it has something to do with oxygen depletion under the central area of the cover slip. It is very common to find that all manner of protists and many bacteria tend to congregate toward the edges, and particul...

Graham... you have always been very inventive! I look forward to seeing more of the results from your hybrid system. I have found that occasionally certain diatoms (and some other "hard" multifaceted subjects like certain amoeba tests made up of tiny sand particles) do not always work out well in DI...

CO 2 is pretty commonly used as an anesthetic in genetic research studies of fruit flies. It will knock out most insects. If you have them in a small container, a short blast injected into the jar will usually do the trick. Ethyl acetate is one of the substances most recommended by entomologists for...

Rik... thanks for posting this, it's fun to see peoples set-ups. Probably there are a lot better ways to get the same or better results, and I hope to hear about them next week. I'm not so sure, looks good to me :wink: Since I suspect there will be interest in this, I hope you don't mind if I throw ...

I am at a loss at why it is so popular You are not alone! I have had a TV as long as I can remember, but when I hear the statistics of the number of hours the "average" person watches each week and compare it to my viewing I am astounded! I have never even seen an episode of American Idol, Desparat...

Amoeba mealtime

I watched this small green flagellate approach and move up against the surface of this amoeba. Big mistake. The amoeba slowly extended a welcoming pseudopod around the little fella, and next thing you know it's a food vacuole! http://www.krebsmicro.com/forumpix/4panelamoe.jpg http://www.krebsmicro.c...

Cyclops (Copepod) "tailfeathers"

The patterns formed by these rear appendages on these tiny crustaceans are fun to examine. While I normally avoid the colorful results possible with the DIC slider, opting for a more "natural" look, I could not resist trying a couple of colorful abstract renditions of this subject. Olympus BHS, Olym...

The monkey part is puzzling... but not the Lewis part: Its species name honors Captain Meriwether Lewis who was the first to collect the plant near Lemhi Pass on the border of today's Montana and Idaho, probably on August 12, 1805; it may be found in the same place today. It was named by Frederick P...

Rik... I had to go back and check since I actually did it last year. There were 94 images in the stack. The background originally was a solid blue, but I fooled around digitally putting some slight cloud "texture" in it.

Subalpine Wildflowers (closeups), Mount Rainier NP

Three wildflowers from a quick trip to Mount Rainier NP. The first is a particular favorite of mine... I'm always amused when I look closely at the tiny, perfect, floral elephant heads .
