The Library of Congress website offers a multitude of historical images, many with no known restrictions on use. This image is derived from the 1925 Keystone stereograph titled President Roosevelt and the noted naturalist John Burroughs, at Fort Yellowstone, Yellowstone Park. The first national park in the world, Yellowstone was established in 1872.

John Burroughs was a naturalist and essayist in America whose nature writings, according to some, are eclipsed only by Thoreau's. Burroughs is credited with initiating the Nature Fakers controversy, an intriguing debate in the early 20th century nature writing, that pitted science against anthropomorphism. The debate initially targeted authors telling false stories about animals but later included authors overly sentimental about the natural world.

CHO Phase Contrast Image-3

Several live Chinese Hamster Ovary (CHO) cells in vitro as viewed through a phase contrast microscope. Visible in the photo are nuclei, nucleoli, mitochondria, and the cell boundary defined by the plasma membrane as well as other yet to be identified cellular structures.

For the next few weeks I will be working with these Chinese Hamster Ovary (CHO) cells in my Molecular Cell Biology course at MTSU. You are looking at an original picture of a group of these cells that we photographed using laboratory equipment (this is not a copy of an image from another source.) These are wild type CHO-K1 cells, the original cell line of which was started in 1957 by T.T. Puck. These cells grow in a monolayer on the bottom of the culture flask. CHO cells are commonly used in biological, genetics and medical research.

Using phase contrast microscopy allows the cells to be viewed live with out traditional staining which requires that the cells be fixed and results in quietus of the organism. Since the cells are living during observation, movement and activity of subcellular components can be easily viewed.
