The collaborative work of graduate student Gabriel Harp and Chris Landau (MFA ’06) on the Organelle View project was published in the January issue of Nucleic Acids Research.
“The project makes a gigantic leap in the distribution of biological data–moving it beyond the conventional representations of names and numbers to embrace the visual and organismal aspects of cellular and molecular forms”, says Harp.
“Organelle View is a scientific visualization application allowing users to dynamically generate a visual interpretation of data from Organelle DB. Organelle View presents a searchable interface with a three-dimensional representation of an archetypical cell. Rather than representing organelles and subcellular structures by text, Organelle View offers an artist’s rendering of a cell and its major organelles. At present, we have chosen a budding yeast cell (S.cerevisiae) as the model for Organelle View, largely because protein localization has been studied quite extensively in yeast; future versions of Organelle View will incorporate additional cell types from other organisms.”

Now more than ever, the concepts, practices, and influences of evolutionary biology communicate experiences of evolution in contemporary life and culture. How do we understand these experiences? The mechanisms of natural selection, sexual selection, migration, mutation, and genetic drift are common in biological systems, yet they are frequently misunderstood. How do we understand and interpret these mechanisms in society? How can we communicate these concepts in ways that also engage our senses?
We broadcast a call for creative work that explores the diversity of forms communicating,commenting on, and engaging mechanisms of evolutionary change and the science of evolutionary biology.
The responses varied. We received submissions largely from artists in six countries and across many different types of media and traditions. In this exhibition, we brought together those works that, through their forms and content, demonstrate the comical, impassioned, and sometimes sublime experiences of everyday evolutionary mechanisms.

Pictured is a comparison of an infected (top) and uninfected (bottom) freshwater snail, Potamopyrgus antipodarum. The parasite is called Microphallus, and can colonize the snail hen the snail passively ingests Microphallus eggs while feeding. The snail serves as an intermediate host for the parasite–meaning that the parasite needs the snail’s resources to develop and reach its next host. Often these final hosts are waterfowl, though in the lab mice are used for experimental purposes.

The cover photograph demonstrates sexual dimporphism in a flowering plant, Silene latifolia. I made the image while working as a research assistant in Lynda Delph’s lab in the Department of Biology at Indiana University in Bloomington. The
Pictured are the female (left) and male (right) reproductive organs. Notice the extreme differences in size. There is enough genetic variation in many populations of Silene latifolia such one can reduce or expand the degree of dimorphism by artifically selecting on a physical trait such as calyx width or flower number.
