Scientific Imaging Contest
The KINSC Scientific Imaging Contest is an annual contest for student-submitted images from experiments or simulations that are scientifically intriguing as well as aesthetically pleasing.
Judging is based on both the quality of the image and the explanation of the underlying science. First, second, and third place winners will have their images displayed on the walls of the KINSC.
First Place: Daniel Feshbach '20
In robotics, coverage considers how to pass over an environment. It is useful in cleaning, mine removal, and more. Here we plan paths for a circular robot which moves at an unreliable angle until encountering a wall. We model the uncertainty and assume worst cases to plan paths which guarantee to cover the depicted regions. Environment walls are black, and colors represent the coverage guarantee under upper bounds on the direction error. They are stacked in increasing order, so the red area (≤ 0.5 ◦ error), while largely obscured, is the largest coverage guarantee because it has the most precise movements.

On a KINSC funded trip to attend the International Pulsar Timing Array annual conference in New Mexico, we were given a tour of the Very Large Array. The VLA consists of 27 25 meter diameter radio antennas positioned in a Y configuration. The size of the configuration can be changed depending on the type of radio observing taking place. Radio telescopes allow us to see objects we normally wouldn’t see in optical wavelengths. With the use of radio telescopes such as the VLA, Professor Andrea Lommen’s collaboration is able to time pulsars in hopes of detecting gravitational waves.

Streptomyces coelicolor is a Gram-positive bacteria belonging to the phylum actinobacteria. This soil-dwelling microorganism biosynthesizes the natural product actinorhodin, a blue-pigmented polyketide antibiotic. When actinorhodin is released into the strain’s growth medium, the medium turns a deep blue. A Streptomyces coelicolor spore grown on a semi-solid agar plate is depicted here. In this image the bacteria has initiated its chemical warfare, releasing actinorhodin into its environment.

Ocean acidification (OA) can negatively impact many calcification-dependent organisms, including corals. In a recent experiment, samples of the octocoral Callogorgia delta were collected from the Gulf of Mexico and exposed to acidic conditions in the laboratory. The effects of OA on C. delta’s skeletal structure can be assayed with scanning electron microscopy by imaging “sclerites” – components of C. delta’s skeleton. By imaging these sclerites exposed to a variety of pH levels (both isolated and within tissue), the impact of OA on C. delta can be characterized. This work aids in identifying species that may be tolerant or sensitive to OA.

Recently, there have been detections of submillimeter galaxies at early redshifts as far back as z~7. In particular, some galaxies have strongly ionized carbon peaks in their emission spectra. In order to better understand the composition of these observed galaxies and the reason for these strong carbon emission lines, I generated simulated galaxies of early redshifts that also contain strong CIII emission in their spectra. This image is a visualization of one of my simulated submillimeter galaxies generated using Powderday and YT. The plot shows regions of extremely high density (i.e. stars and dust) in white.

Many materials exhibit photoelastic effect. What is photoelastic effect? When we put a stressed photoelastic material between optical filters, we see fringes on the material: some area is darker and some area is lighter. The variation of the intensity of lights passing through the material corresponds to the variation of the stresses within the material, and hence physicists use this effect to visualize and analyze the distribution of forces in materials. The photo above shows fringes in a photoelastic particle when it was squeezed diametrically. This research was advised by Professor Ted Brzinski at Haverford College.
First Place: Annika Salzberg '19
Trissolcus japonicus, a parasitic wasp in the superfamily Platygastroidea, emerges from a hemipteran egg. This wasp and other parasitoids of hemipterans are being studied for their possible use as a biological control agent against invasive brown marmorated stink bugs. This image was created at the Smithsonian Museum of Natural History under the supervision of Dr. Elijah Talamas using stacked light microscopy and Adobe Photoshop. It consists of over 42 stacked images, each containing between 15 and 80 images each. Special credit: USDA/Systematic Agricultural Research Service.
Second Place: Kate Rose Sullivan '18
Macrophages release calreticulin, an endoplasmic reticulum chaperone protein, to bind to target cells. Calreticulin binds to unique glycoepitopes on the cell surface. The regulation of this glycoepitope mediates the cellular localization of calreticulin and, ultimately, immune recognition for tissue homeostasis. This image demonstrates the cellular distribution of the glycoepitopes (green) within macrophages that are actively releasing calreticulin. Cell surface glycoepitopes are observed outside of phalloidin stain (red), which labels actin filaments at the periphery of the cell and dapi (blue) staining the nucleus. Confocal images were acquired in the laboratory of Dr. Irving Weissman at Stanford University and was funded by the KINSC through the Frances Velay Summer Scholars Program.
Third Place: Gabe Oppler '17
Detailed view of scalariform pitting on a stem xylem tracheid of Psaronius, an extinct tree fern from the Pennsylvanian subperiod of the Carboniferous (323-299 Ma). This tracheid was embedded in a fossil from the West Mineral, KS formation. The fossil was macerated in hydrochloric acid to liberate the organic material as part of Gabe Oppler’s investigation into the stem and root anatomy of Psaronius. Imaged under the Haverford College Scanning Electron Microscope (SEM) at 2,200x magnification.
First Place: Chloe Wang '17
This image shows an optical micrograph of corroded stainless steel, taken at Lawrence Berkeley National Laboratory during the summer of 2015. Corrosion was accelerated by an applied voltage in an electrochemical experiment, transforming this piece of stainless steel foil from a uniform sheet to a landscape of jagged holes and colorful metal oxides.
Second Place: Christopher Nagele '16
This is an image of one component of a stellar magnetic field. Stellar magnetic fields have profound effects on the spin and lifetime of their stars, but they are often mathematically complicated. It turns out that any complicated field can be built using combinations of simple fields. Analyzing the behavior of simple fields such as this one allows us to better understand the complicated behavior of real stellar magnetic fields. In this image, hotter colors denote a weaker field and are generally found farther from the star.
Third Place: Caleb Eckert '17
As part of a BioArt collaboration, HC/BMC students and artists from the Center for Creative Works, a vocational art program for adults with disabilities, painted agar plates with colorful strains of Streptomyces bacteria to produce the living biological artwork seen in the image.

The effect of Interleukin 13 (IL13) on cultured small intestine epithelial cells from a normal patient. The cultured cells show several crypts and villi characteristic of the intestinal epithelium. Cell membranes are stained green, mucin is stained red, and cell nuclei are stained blue. IL13 is a cytokine involved in inflammatory and anti-inflammatory pathways in the airways and intestinal epithelium (1). Here, the response of healthy small intestine epithelial cells to IL13 treatment is shown to involve goblet cell (mucin-producing cells) hyperplasia and mucin hypersecretion.
Second Place: Rui Fang '17
A plastic fork viewed through crossed polarizers shows beautiful multicolored patterns. This is due to birefrigence of plastics. In birefringent materials, the index of refraction of a plane-polarized light can take on two values, resulting in a phase retardation which changes the polarization of transmitted light. Different colors of light have different indices. So, through another polarizer, a fringe pattern is revealed due to color interference. Because the pattern is indicative of the varying birefringence of the material, this method called photoelasticity is often used for analyzing stress distribution.
Third Place: Matteo Miazzo '15
As part of our research, we induce controlled flow using electric and magnetic fields to produce Lorentz forces within a conductive fluid. In order to characterize this flow field, we need a way to visualize the motion. Tracer particles are seeded on top of the fluid; these particles are tracked and the paths are analyzed, allowing us to determine specific characteristics of the flow field. This image shows the paths of individual tracers, which have been randomly colored to distinguish between different particles.
