• June 4, 2006: UltraScan 8.0 released
  Changes in this release include improvements in the database code for managing experimental result data. Major re-design work has been accomplished on the Windows version of UltraScan to permit directly communicating with the public UltraScan LIMS, and to facilitate public supercomputer access. In addition, a redesigned archiving utility now offers complete platform portability of UltraScan data archives between all platforms.

• April 4-5, 2006: UltraScan Workshop at the 15th International AUC Conference

• March 25, 2006: Public UltraScan LIMS Portal released

  This website provides public database support for the UltraScan Laboratory Information Management System (LIMS) to users of the UltraScan software. You can use this portal to store your sedimentation data and associated data for your experiments in the UltraScan LIMS. Authorized users can use this portal to gain access to our HPC supercomputing resources.

• March 11, 2006: UltraScan 7.3 released

  This release offers a number of new features, among them is one that allows exchange of finite element models between different methods. All models can be loaded into the new Finite Element Matching program that allows to view residuals, time invariant noise, and 3D distributions for Spectrum Analysis plots. Also available is a new portal that permits access to a remote cluster for faster 2-D spectrum analysis on a parallel system. Also available is a downloadable archive of the complete UltraScan source code.

• February 26 - March 1, 2006: 2006 Workshop

  For more information, please visit the UltraScan Workshop page.

• July 17, 2005: UltraScan 7.2 released

  This release includes an important bug fix in the enhanced van Holde - Weischet method that avoids the "Not enough datapoints for divsion..." error. Also, the equilibrium fitting routine has been re-written to gain a significant 12-15 fold speedup during fitting, especially for very large datasets with many scans. This version also includes a preview of the 2-dimensional spectrum analysis.

• June 27-29, 2005: Analytical Ultracentrifugation Workshop

  Please mark your calendar for this year's Analytical Ultracentrifugation Workshop. The workshop will focus on problem solving with the analytical ultracentrifuge. The topics will range from hydrodynamic theory, experimental design, hands-on software training with UltraScan for data analysis and presentation, the new LIMS database system, and training on how to maintain the XLA/I instrument and diagnose instrument problems.

• April 28, 2005: UltraScan 7.1a released

  This release includes several bug fixes and offers three new ports of UltraScan: NetBSD, Sun Sparc Linux, and Sun Solaris 9.

• April 10th, 2005: UltraScan 7.1 released

  This is mostly a maintenance release with several bug fixes and also some GUI improvements.

• February 18th, 2005: UltraScan 7.0 released

  Among the new features:

  • All new LIMS database system
  • LIMS web portal for use with Apache and PHP module.
  • LIMS C(s), C(D) and C(MW) implementation
  • New highly efficient and highly accurate Finite Element implementation for Lamm equation solution (Adaptive Space-Time Finite Element Method: ASTFEM - submitted to Biophysical Journal)
  • New License Manager simplifies dealing with UltraScan licenses
  • Documentation updates
  • lots and lots of bug fixes,

• September 1st, 2004: UltraScan AccessGrid Seminar Series Announced
