image: This is an optical micrograph of an ultrastable gold substrate that improves the imaging resolution of electron cryomicroscopes. Each hole, which is used to support frozen samples in the vacuum of the electron microscope, is approximately one micrometer in diameter. This material relates to a paper that appeared in the Dec. 12 2014 issue of Science, published by AAAS. The paper, by Christopher J. Russo and Lori A. Passmore at Medical Research Council in Cambridge, UK, was titled, "Ultrastable gold substrates for electron cryomicroscopy." view more
