Seattle, WA - July 9, 2003 - VizX Labs today announced the release of the Version 2003.3 update to GeneSifter.Net. Available online now, the update was delivered complete and ahead of schedule to GeneSifter.Net users.

"Biological science changes daily," said VizX CEO Tom Ranken. "Operating GeneSifter.Net through the Internet enables us to update biological data, add new statistical methods, and enhance other features instantly. The result is that the latest scientific techniques are automatically available to every user of GeneSifter.Net with each quarterly release."

Version 2003.3 adds important new features to GeneSifter.Net that take advantage of its web-based design by integrating biological information from diverse online sources. For example, GeneSifter's One-Click Gene Summary™ now features links to metabolic pathways diagrams and genetic researchers can now easily find known functions of genes with the new Ontology Overview Report. The release also adds powerful statistical techniques and integrates new biological information. Enhanced functionality assists users in navigating through the system, exporting data, and creating graphics.

Today's announcement continues VizX Labs' unique program of quarterly updates of the GeneSifter.Net system to keep researchers ahead of the curve on the latest developments in statistical analysis, data management, and genomic information.
