Building a digital ant gallery, from the ground up

A project called Antscan has generated high resolution images of thousands of ants, representing over 700 species. To make it happen, researchers brought preserved ants from collections around the world to a particle accelerator in Germany. There, a powerful synchrotron X-ray source combined with a vial-swapping robot allowed the researchers to build a collection of 3D ant images, inside and out. Each voxel (like a 3D pixel) has a resolution of 1.22 micrometers—enough to see the tiny hairs on ant bodies, and distinguish individual muscle fibers. Antscan researcher Julian Katzke joins us to describe the background of the project, and how the images could be used for science and art. Check out Antscan images at our website. Guest: Dr. Julian Katzke is a postdoc at the Smithsonian National Museum of Natural History.  He worked on the AntScan project while a PhD student at the Okinawa Institute of Science and Technology.
