Confocal snapshot of the junction between two portions of the Drosophila digestive tract: the midgut and the hindgut. Cell nuclei are labelled in blue, membranes in green and muscles in red. This image was taken by Irene Miguel-Aliaga. {Source.}
This is irresistible. In a paper published in the journal Cell Metabolism, biologists at the University of Cambridge use an imaging method to:
uncover a central role for the Drosophila intestine in the regulation of nutrient intake, fluid, and ion balance.

Isn't this a lovely example of the beauty of nature, even if it is hidden in the digestive tract of a fruit fly?

THE humble fruit fly (Drosophila melanogaster) has the ability to learn and remember, and to make predictions about the outcome of its behaviours on the basis of past experience. Compared to a human brain, that of the fruit fly is relatively simple, containing approximately 250,000 cells. Even so…
For most of the nineteenth century, there was an on-going debate among researchers about the organization of the nervous system. One group of researchers, the so-called reticularists, believed that the nervous system consisted of a large network of tissue, or reticulum, formed by the fused…
These pictures are stunning. I loved looking at them because I spent 4 years of my life studying the development of the fly renal tubules (which arise at the junction between the hindgut and midgut as in the first pic you posted). People used to back away from me slowly at parties when I started going on about how beautiful they were--wish I'd had pics like this to show them!
