This image may look like some kind of neon winter wonderland,
but it is actually a microscopic view inside a human intestine. More specifically, the image
represents the cells that make up intestinal tissue. They just so happen to
look like Christmas trees, together with a bit of snow from Photoshop! Dr Alex
Greenhough and Paloma Ordonez Moran from the School of Cellular and Molecular
Medicine at the University of Bristol created the image.
