Sperm quality analyses in good and bad zebrafish breeders. (A) Representation of total population distribution in terms of total motility (%). (B) Total motility (%) at different post-activation times (15 s, 30 s, 45s and 60 s) in the experimental groups (good and bad breeders)...
One possible explanation is that microscopy has been mainly applied to transverse sections, in which xylem modification would not be obvious. Even when longitudinal sections were used, research interest was focused on nematodes and/or their feeding sites, and structural modification of the xylem might...
it seems that a successful scientist is full of curiosity--he wants to find out how and why the universe works.He usually directs his attention towards problems which he notices have no satisfactory explanation,and his curiosity makes him look for underlying relationships even if the data ...
The year 1905 is sometimes called Einstein's annus mirabilis (miracle year). In that year he published four outstanding scientific papers: An explanation of the photoelectric effect indicating that light energy came in chunks or quanta. This changed thinking on the nature of light. A discussion ...
about the manymeaningsof the tetractys symbol. Most such details are dubious. The tetractys is essentially a symbol for the counting numbers themselves (1, 2, 3, 4...). This sign evokes the Pythagorean belief system which puts small whole numbers at the core of every fundamental explanation....

If you think some agent like microplastics or power transmission lines in the environment can cause illness then you need to come up with a local explanation of why and then test it. For example, microplastics might cause health problems by stimulating immune cells and cause excessive inflammation...
It should be noted that although we observed significant changes in inflammatory markers in the liver, the inflammatory foci did not show a significant difference in the histological sections. One possible explanation for this discrepancy could be that the changes of gene and protein expression level...
