Evident Image of the Year global winner: Cross-section of a Cosmic Orange aster flower with pollen grains maturing inside anthers. Captured by Igor Siwanowicz of the United States. Igor Siwanowicz of the United States was selected as the global winner for his striking cross- section image of a Cosmic Orange Mexican aster flower that vividly depicts pollen grains maturing inside anthers. To create this image, Siwanowicz embedded isolated florets in agarose, sectioned on a vibratome and stained with Calcofluor White and Congo Red dyes. The sample was dehydrated, cleared and mounted in methyl salicylate. Siwanowicz chose to image this flower to observe how aster florets are organized before the flower opens. ?I was lucky to pick my flower buds at the right stage of development, with the pollen grains almost fully mature but still bound together in a mass,? Siwanowicz explained. ?I think this image shows the true beauty of a common flower that most of us take for granted by extending it well beyond what we can see with the naked eye. The beauty of natural form and design is present on very different scales, sometimes almost in a fractal manner?as we continue to zoom in, the form may lose familiarity but also become a new emotional experience.?
