The following links pertain to histological artifacts.  These are structures or colors that are seen under a microscope that have no correlation to the biological state of the tissue.  We can see something that looks like a vacuole that is just a hole.  We can see a free floating nuclei that is simply some granulated stain on the slide.  Be careful to note when and where artifacts may happen.  It is unlikely that anything we find will actually be alien or a new discovery:
