*Vote for OpenSim!* You can help us win the NIH Song and Video Competition. Just watch and *Click Like* for the OpenSim video<https://www.youtube.com/watch?v=HLFQM1e-vJw&feature=youtu.be>. The deadline is May 9th. We are excited to be competing with this video in the NIH Common Fund Song and Video Competition <http://commonfund.nih.gov/Contests/videos>. The top 4 or 5 videos with the most “Likes” on YouTube will be shown during the Common Fund 10-Year Commemoration Symposium this June. We’d also appreciate you forwarding this to others (including colleagues, friends, and family!). *Congratulations to the Dynamic Walker Challenge Winners* We are pleased to announce the winners of the OpenSim Dynamic Walker Challenge<http://simtk-confluence.stanford.edu:8080/display/OpenSim/Dynamic+Walker+Competition+January+2014>. Geena Doak, Matthew Handford, and Alex MacIntosh each created dynamic walkers to traverse a complex terrain in OpenSim. See their videos<http://www.youtube.com/playlist?list=PLGBiefGDmSuQ-Z00FRcQpfbgRowMIxPKJ>on the OpenSim YouTube page. *OpenSim Symposium at the World Congress of Biomechanics* The World Congress of Biomechanics in Boston will feature a symposium showcasing research from nine investigators<http://www.stanford.edu/group/opensim/support/event_details.html?id=99&title=OpenSim-Symposium-at-the-World-Congress-of-Biomechanics>from the OpenSim community. The symposium is scheduled for the morning of Thursday, July 10. Learn more about the World Congress and register on the WCB website <http://wcb2014.com/>. *OpenSim Workshop at the Summer School on Neurorehabilitation* Massimo Sartori and Monica Reggiani will lead an OpenSim workshop at SSNR 2014 in Baiona, Spain. Participants will be introduced to the theory behind simulation of musculoskeletal movement in OpenSim, along with the framework of the software architecture via hands on Matlab scripting exercises. Read more and find out how to register on the workshop website<http://www.ssnr2014.org/workshopMusculoskeletal.html>and the SSNR 2014 main page <http://www.ssnr2014.org>. *New Shared Simulation Data for Running* Sam Hamner has recently posted the full dataset from his study of multi-speed running <https://simtk.org/home/nmbl_running>, so others can reproduce and extend his work. Providing shared resources for the biomechanics community is one of the core goals of the OpenSim project. We encourage you to share your models and simulations after publication. Let us know if you do and we'll add a link to our data library <https://simtk.org/home/opensim_data/>or model repository<http://simtk-confluence.stanford.edu:8080/display/OpenSim/Musculoskeletal+Models>to improve the visibility of your research. -- *Jennifer Hicks, Ph.D.* Associate Director | NCSRR<http://www.stanford.edu/group/opensim/about/index.html> R&D Manager | OpenSim <http://opensim.stanford.edu/> Stanford University 650-498-4403 | jenhicks@stanford.edu
