March 2012 - As of March 16th, museum visitors can explore the hidden world of cells at Naturalis. A new exhibit called the Cell Zoomer will be placed in the hall Research in Progress. The exhibit consists of an enormous touch screen that allows visitors to zoom in on the tiny body of a zebra fish. The animal was mapped microscopically by the Electron Microscopy Section of Leiden University Medical Centre. This innovative visualisation technology allows scientists to study a complete animal at the cellular level for the first time.
