Technique adds color to electron microscope images

Researchers at the University of California at San Diego have developed a technique that adds color to black-and-white electron microscope images. The scientists create a black-and-white base layer by adding a heavy metal to the specimen, then create another layer by adding a rare earth metal that clings to specific molecules and assigning a color to it, making those molecules stand out.

Color images reveal details about Schiaparelli crash on Mars

Color images released Thursday show more detail of the site where the European Space Agency’s Schiaparelli lander crashed as it attempted to touch down on Mars last month. The photos, taken Tuesday with the Mars Reconnaissance Orbiter’s high-resolution camera, indicate the lander’s parachute has shifted positions since the crash, likely due to the planet’s wind, and more images will be taken in about two weeks to see whether any other changes occur.
