Winner: Best Scientific Visualization SC19; Primary energy source of life from Birth of Planet Earth TCBG UIUC 2019-12-16 | Winner: Best Visualization Award, Scientific Visualization & Data Analytics Showcase, SC19 conference. "An accessible visual narrative for the primary energy source of life from the fulldome show Birth of Planet Earth" (Accompanying paper: sc19.supercomputing.org/proceedings/sci_viz/sci_viz_files/svs110s2-file1.pdf)Conversion of sunlight into chemical energy, namely photosynthesis, is the primary energy source of life on Earth. An explanatory visualization depicting this process is presented in the form of an excerpt from the fulldome show Birth of Planet Earth. This accessible visual narrative shows a lay audience, including children, how the energy of sunlight is captured, converted, and stored through a chain of proteins to power living cells.https://www.ks.uiuc.eduhttp://avl.ncsa.illinois.eduspitzcreativemedia.com

Mechanism of Bacterial Adhesion in Staphylococcal Infection Revealed with Atomic detail TCBG UIUC 2018-03-29 | What makes pathogenic bacteria so persistent? Researchers from the Beckman Institute at the University of Illinois and the University of Munich (LMU) decipher the physical adhesion mechanism of a widespread pathogen virulence factor. Staph infections are caused by staphylococcus bacteria, types of germs commonly found on the skin of healthy individuals. Most of the time, these bacteria cause no problems or result in relatively minor skin infections. However, according to the Mayo Clinic, septicemia (also known as blood poisoning) can occur when staph bacteria enter a person’s bloodstream. The bacteria can travel to locations deep within the body causing infections. Particularly vulnerable regions are medical devices such as artificial joints or cardiac pacemakers. Not surprisingly, staph infections are the leading cause of healthcare-related, so called nosocomial infections.Read more:http://science.sciencemag.org/content/359/6383/1527

Developing a Complete In Silico Model of a Minimal Cell TCBG UIUC 2016-12-04 | This video illustrates the vision of the Center in developing a complete in silico model of a minimal cell. It was submitted as part of the Center's collaborative application to the MacArthur Foundation's 100&Change program. In collaboration with geneticists and microscopists, the Center will leverage its large-scale modeling software and expertise to completely describe a 400 nm cell on all time and length scales, helping to usher in a new era in biomedicine.Materials taken from Center work or collaborators, except for the Biochemical Pathways poster (created by Dr. Gerhard Michal; electronic version: © 2014 F.

Example VMD VR movie: inside the HIV-1 capsid TCBG UIUC 2016-03-24 | This video is an early example of VR movies that can be produced with the latest versions of the popular molecular visualization program VMD.For best 3-D viewing, use the YouTube player app for your smartphone with a Google Cardboard VR viewer, or similar (g.co/cardboard), and set the video quality to the highest setting that your device can play smoothly.The movie will also play in a standard desktop or tablet web browser, however it will not be shown in stereo 3-D, although you can still use the mouse to rotate the view around you as the movie plays.About the movie:This movie shows the interior of the HIV-1 capsid and solvent bath, but with only 1% of the ions shown in the solvent for ease of viewing.Learn more about the HIV-1 capsid and other retroviruses here:http://www.ks.uiuc.edu/Research/HIVThe omnidirectional stereoscopic ray tracing techniques used for production of this movie are described in our paper: "Atomic detail visualization of photosynthetic membranes with GPU-accelerated ray tracing":http://dx.doi.org/10.1016/j.parco.2015.10.015The movie was rendered a 4096x4096 resolution using an omnidirectional stereoscopic projection, with ambient occlusion lighting and shadows. The movie was produced running VMD in parallel on the Blue Waters Cray XK7 supercomputer at NCSA, U. Illinois, using 256 NVIDIA Tesla K20X GPUs with the TachyonL-OptiX GPU-accelerated ray tracing engine implemented in VMD 1.9.3.For more information about VMD, please visit the VMD home page:http://www.ks.uiuc.edu/Research/vmd/
