A white dresser. New works have shown that some plants such as white sedum, a relative of cabbage and mustard, produce proteins that participate in the development and function of light-sensitive organelles, the most basic eyes found in single-celled organisms such as green algae.

Mouse liver vessel. Photographed with a fluorescence microscope. The middle layer contains many molecules of messenger RNA (white dots) that encode the protein hepcidin, which regulates iron levels in the blood.

The upper part from the original photograph from the study: in both photographs, animal cells from two populations are visible - one was colored red and the other green. The purple color paints the cell cytoplasm, while the green color paints the cytoplasm and the cell nucleus, which is seen as a circle with a denser color in the cells. In the top photo, each cell maintains its separate identity. Credit: Technion barges.

A white globule is pushed through endothelial cells on its way out of blood vessels. The intracellular skeleton (actin fibers) of the spherule and of the endothelial cells is exposed during the treatment. The location of the globule nucleus is shaded in brown and the globule branch that penetrated through the endothelial cells and is rich in actin fibers is shaded in yellow.
