apochronaut wrote Interesting to read several of the well intentioned but glib comments. I can assure you that you have no idea how out of touch with reality they are. I cannot imagine the heartaches that apochronaut and his daughter have had to face, and I have great sympathy for them and the rest ...

For quite a number of years now in my country, and I think in many, if not most western countries, mental health issues have been increasingly identified as a relatively common and serious area of concern, not just for the individuals affected but for society as a whole. There is growing concern abo...

Beautiful! (The rotifer, the video and the wetland)

HI Bob
I agree. Nice differentiation and I do like the colours.

Hi Antoni Glad to hear you are thinking of ordering the book; I think you'll find it very helpful. I should mention that the author, Eric Marson, operated a business called Northern Biological Supply (NBS) which sold slides and slide making equipment and supplies. So many of the reagents mentioned i...

Hi AntoniScott There are a great many references that could be given in answer to your question, but two that I would recommend are: Practical Microscopy by J. Eric Marson. Available from Brunel Microscopes in the UK for 12 GBP. This is general in its coverage (including botanical stains), but geare...

Terrific reference AntoniScott. Thank you very much!

Outstanding!

Ah, Bob. I'm afraid it will need more than a little polish! But I suspect the video will be very informative no matter what the language.
Tom W.

I agree with deBult on the apparent differentiation, but I like them both very much. Very attractive images for such thick sections. I too would like a link to the video.
Cheers

HI Greg I can't speak to the 2x Barlow, but I bought a 0.5x supplementary lens for my stereo scope to give a wider field of view, and increased clearance for large samples when needed. My scope uses a dovetail column rather than a round column, and so has a limited range of adjustment. I found that,...

Very, very interesting indeed to see that. Thanks for sharing.

Thanks for the response Naphthalene. I have done a little research since reading your original post. Wikipedia for example has quite a good article at https://en.wikipedia.org/wiki/Subcommissural_organ . For an organ that has been identified for such a long time, is evolutionarily ancient, is create...

Very nice work Naphthalene. Very nice sections and images indeed. I'm assuming the triangular structure in each image is the section of the subcomissural organ? I had never heard of this before, and wonder if there are any hypotheses as to it's specific secretory function.

Thank you mrsonchus
These are quite a bit more informative than the previous "No Entry" signs Very nice to see the technique so well used on botanical samples, rather than the usual pond life studies.
Tom W.

For some reason or other I can't see your images John. Am I the only one so affected?
Tom W.

Nicely done. There seems to be enough variety in the aquarium to keep anyone busy for quite a while!

Can you give me any idea (order of magnitude: minutes, hours, days) of how long it takes from completion of conjugation to completion of the programmed nuclear death process - i.e. complete resorption of the fragments of the old MAC? I wasn't sure so had to check the literature and it appears the p...

Excellent work Wes! The images are not only instructive but also attractive. Can you give me any idea (order of magnitude: minutes, hours, days) of how long it takes from completion of conjugation to completion of the programmed nuclear death process - i.e. complete resorption of the fragments of th...

Quite spectacular! Thanks for sharing.

Hi DonSchaeffer
Yes, I do like that picture!

You might also try to buy or borrow a copy of "Explore the World Using Protozoa" by O. Roger Anderson & Marvin Druger published by NSTA Press (1997).

I'm not sure if this article is accessible without a subscription to New Scientist, but if it is, it's an interesting read. https://www.newscientist.com/article/2252583-secret-to-tardigrades-toughness-revealed-by-supercomputer-simulation/ I suspect Nature will include an article on it in their brief...

Very nicely done with an excellent choice of music. Thank you.

Apparently eosin aqueous solutions are very prone to mould growth, so I suspect bacterial growth could also be an issue.
