The bursts of rainbow colors in this photograph are mesmerizing, yet microbes are fighting for their lives in the background. Michael P. Zach of the University of Wisconsin-Stevens Point, snapped this image of a salt sample he collected in a hot, arid valley near Death Valley National Park in California. Zach crushed the salt, placed it under a microscope slide and added a drop of water. Suddenly a slew of microbes came to life as the salt crystals dissolved, and when the water started evaporating, he took a picture. The colors come from light passing through the growing crystals, which act like prisms.
