Volume VIII – March 2019 - Cover Photo: Tessellations combine the creativity of art with the laws of mathematics in the formation of beautiful patterns. By utilizing specific shapes and commands, one can generate countless varieties of patterns such as the one pictured on this year's cover. The basis of such patterns can be a simple shape or a more complicated image, such as the M.C. Escher-inspired pattern shown here (image created by Leonardo J. Anselmo '19).
Volume VII – March 2018 - Cover Photo: The Principles of Biology Laboratory (BIOL 151) has focused on exploring the microbiome of the common hop Humulus lupulus for the past 3 years as a means of giving students the opportunity to develop and implement their own unique research questions. Here, students allowed a hop leaf to grow on a petri plate with rich growth medium for microbes, and the result was a pristine configuration of bacteria and fungi in the precise shape and venation pattern as the leaf (Photo credit: Dakota M. Reinartz '18).
Volume VI – March 2017 - Cover Photo: Sea turtle breeding grounds are increasingly threatened by human encroachment, and the breeding grounds of the Cape Hatteras National Seashore are no exception. On this map of the Seashore, sea turtle nesting areas are monitored using a technology called Turtle Sense to gain more information on timeframes for hatching and emergence of a new generation. To learn more about this technology, check out the Turtle Sense article by Joshua Chamberlin '17 and Erin Clabough in this issue.
Volume V – March 2016 - Cover Photo: Using antibodies attached to fluorescent molecules along with advances in microscope technology, scientists can track the precise positions of structures within the cell in exquisite detail. Here, mammalian T cells have been treated with drugs designed to inhibit actin cables being visualized with red and green fluorescent molecules that label specific regions of the cell. By taking multiple images of these labeled cells and running them together into a movie, the precise motion of the actin cytoskeleton in response to immunological challenge to the T cells is revealed. This image was taken in the laboratory of Dr. John Hammer at the National Heart, Lung, and Blood Institute of the National Institutes of Health, Bethesda, Maryland (From J. Taylor Meinhardt '16 under the supervision of Dr. Sricharan Murugesan).
Volume IV – March 2015 - Cover Photo: Green fluorescent protein (GFP) has revolutionized molecular biology by allowing scientists to label individual proteins in a cell or, as in this photo, entire organisms. Here, the nematode Caenorhabditis elegans, a common model organism in the study of developmental biology and genetics, is labeled with GFP to provide a clear view of its body plan. The photograph was taken in the Fall 2014 semester in Gilmer Hall at Hampden-Sydney. Note the unborn C. elegans that can be seen developing inside the adult nematodes. (From Grayland W. Godfrey '15)
Volume III – March 2014 - Cover Photo: The Phamerator database is used to compare whole bacteriophage genomes for similarities and differences that will uncover information on the progression of bacteriophage evolution. The coloration between the lines in the above figure indicate regions of high sequence similarity between the genomes under comparison. (From James B. Hughes ’14)
Volume II – March 2013 - Cover Photo: This figure shows the block diagram of a virtual instrument (VI) designed to operate a UV-vis spectrometer and a potentiostat in tandem. This particular VI aids the operator in conducting spectroelectrochemistry experiments, and it will also automatically save the results of the experiments to text files for data analysis (From Stephen D. Nelson ‘13).
Volume I – March 2012 - Cover Photo: Using immunofluorescence and Calcofluor White staining, proteins called septins can be observed at the division points of budding yeast cells (Saccharomyces cerevisiae) along with an outline of the cell wall.
