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.
