1) Daily Regional Weather Forecasts in Support of Vortex2. Quan Zhou, Beth Plale, Keith Danielson, Robert Ping, Janae Cummings and Alan Mauro. The Vortex 2 campaign funded by the National Science Foundation was a 6-week effort Spring 2010 to position instruments near mesoscale severe storms as they were forming. The Data To Insight Center of Indiana University executed short-term regional weather forecasts each day of the 6-week campaign. The visualization unfolds the daily location of a regional weather forecast done in support of Vortex2 field effort that took place May-June 2010 by using the World Wide Telescope (WWT) Tool - a web 2.0 visualization software environment. Moreover, this visualization uses times series and three-dimensional geospatial visualization techniques to display spatial distribution and temporal relation for Vortex2 data set. The video employs voice-over and text to convey the importance of a forecast in relation to actual weather.

2) Gallery of images created in live leaves by chloroplast movements. Margaret Dolinsky and Roger Hangarter. Our objective is to showcase an art/science collaboration in which aesthetic experience is the vehicle to examine photosynthesis in the context of its central role in life on Earth. This collaboration has resulted in a collection of high resolution images and time-lapse movies that reveal the process of chloroplast movements. The images portray the movements as they occur from the level of a single cell to the whole leaves. The resultant images display how the subcellular changes affect the optical properties of leaves, which illustrates how chloroplast positioning maximizes photosynthesis. This presentation will give visitors the opportunity to examine the results of how chloroplasts act as living pixels that move in response to light to render the art in a living canvas. The exhibition will display a number of high resolution art images created in living leaves to illustrate the dynamic biology of green plants.

3) High Performance Computing for Designing Groundwater Remediation Systems. Loren Shawn Matott, Camden Reslink, Christine Baxter, Beth Hymiak, Shirmin Aziz, Adrian Levesque and Martins Innus. This research involves the design of cost-effective systems to safeguard the nation's groundwater supplies from contaminated sites. What looks like a colorful whirlpool in the image is actually a remediation cost-surface containing many peaks and valleys. Valley locations outside of the red area are sub-optimal and easily entrap computer algorithms which seek to identify the best design point on the cost surface. In this way the image dramatically illustrates the problem of "artificial minima" which bedevils engineers tasked with cleaning up solvent-contaminated groundwater.

4) Molecular Simulations of the Dynamic Properties of Wild Type and Mutated 14-3-3σ Proteins. Albert, William, Michael Boyles, David Reagan, Jing-YuanLiu and Divya Neelagiri. Protein-protein interactions are important for biological functions. Aberrant interaction events can cause diseases such as cancer and diabetes, yet how proteins recognize each other and form stable complexes is not fully understood. In this work, we used 14-3-3σ as a model and introduced small changes that alter the binding affinity of the protein chains. We then investigated the dynamic properties of the interfacial cores of the wild type and mutant 14-3-3σ by performing water explicit molecular dynamics simulations. We observed a highly packed interfacial core that has a low water exchange rate in the wild type 14-3-3σ but not in the F25G mutant. This suggest that the properties of the interfacial core are critical to specific protein-protein interactions and that the interfacial core may serve as the nucleation seeding site for strong hydrophobic interactions which has been recognized as the driving force for protein association. The outcome of this study will help us understand the principle question of how proteins recognize each other. The molecular dynamics simulations were computed using Indiana University supercomputing resources. Visualizations were produced using the Visual Molecular Dynamics (VMD) software. Artistic enhancements and final video production were accomplished using Autodesk Maya and Adobe After Effects.

5) Places & Spaces: Mapping Science. Katy Börner and Todd Theriault. For centuries, cartographic maps of earth and water have guided human exploration. They have marked the border between the known and the unknown, firing the imagination and fueling the desire for new knowledge and new experience. Over time, geographic maps have become more accurate, more sophisticated, but the thirst for discovery, along with the need for maps to guide our travels, remains undiminished.

Today, our opportunities for discovery reside less in physical places than in abstract spaces. The sea of information is one such space, and it is ever growing, ever changing. Search engines can retrieve facts from this ocean of data, but they cannot answer larger questions about the seascape as a whole: How big is this ocean? How can we navigate to the useful islands of knowledge? How is knowledge interlinked on a global scale? In which areas is it worth investing time, effort, and resources?

Drawing from across cultures and across scholarly disciplines, the Places & Spaces: Mapping Science exhibit demonstrates the power of maps to address these vital questions about the contours and content of human knowledge. Created by leading figures in the natural, physical, and social sciences, scientometrics, visual arts, social and science policymaking, and the humanities, the maps in Places & Spaces allow us to better grasp the abstract contexts, relationships, and dynamism of human systems and collective intelligence.

Now entering its ninth year, the exhibit has traced the evolution of science maps, featuring the best examples of knowledge domain mapping, novel location-based cartographies, data visualizations, and science-inspired art works. Individually and as a whole, the maps of Places & Spaces allow data to tell stories which both the scientist and the layperson can understand and appreciate.

6) Visualization of Globular Star Clusters. DavidReagan, WilliamSherman, Enrico Vesperini, Anna Lisa Varri and Chris Eller. Dr. Vesperini uses IU’s supercomputers to simulate the formation and dynamical evolution of globular star clusters. Indiana University’s Advanced Visualization Lab utilized the open-source application ParaView to create visual representations of three such simulations. The first shows the gravitational collapse of a globular cluster. The second follows the evolution of two stellar populations in a globular cluster. The third shows the evolution of a rotating stellar system with a central toroidal (or donut-shaped) structure.

7) Visualization of Nuclear Pasta. DavidReagan, Andre S.Schneider, Charles J.Horowitz, JosephHughto, Don K.Berry, Eric A.Wernert, and Chris Eller. Some massive stars die in giant supernova explosions that squeeze all of the empty space out of atoms until their nuclei start to touch and interact in complex ways to form a neutron star 100 trillion times denser than water. Dr. Horowitz and his group use IU’s supercomputers to simulate these events, where nuclei merge into spaghetti- and lasagna-like structures called nuclear pasta. Indiana University’s Advanced Visualization Lab utilized the open-source application ParaView to create stereoscopic visualizations which allow the researchers to study the formation of these intricate structures and explore their properties.

8) Visualization of the Buffalo Inner and Outer Harbor. Martins Innus, Adrian Levesque, Ayla Abyad, Jacob Brubaker, and Hans Baumgartner. We will describe our experience developing an interactive visual application which supports the study of viable Buffalo Harbor Bridge locations and alternatives, as well as helping advance the project through an Environmental Impact Statement (EIS), by providing stakeholders and inte
