Photography: DNA

Posted Posted in Arts

By Riley Galton, Genetics ’14 Deoxyribonucleic acid, or DNA, encodes all of the instructions necessary for the beautiful figures and forms that can be found in the biological world. All plants, animals, and humans— subjects that are so familiar to the photographer—share the same underlying, four-letter genetic code. It is this simple molecular code that gives rise to the incredible diversity of living things, which in turn makes them so rewarding to photograph. My goal for this project was to investigate the form of the DNA itself—a form that is seldom seen, but always there. To do this, I isolated DNA from strawberries and photographed it using a macro lens.

Population Vector

By Jennifer Jahncke, Psychology ’14 Something we talk about a lot in neuroscience in terms of topics like visual perception and locomotion is population vectors. A population vector is the sum of each component vector. In this image, with the trees converging to a vanishing point, the population vector would be the vector in the center of the cluster (though not quite to scale; in reality it would have a larger magnitude).
