New Imaging Technology Could Reveal Cellular Secrets

Researchers have married two biological imaging technologies, creating a new way to learn how good cells go bad. "Let's say you have a large population of cells," said Corey Neu, an assistant professor in Purdue University's Weldon School of Biomedical Engineering. "Just one of them might metastasize or proliferate, forming a cancerous tumor. We need to understand what it is that gives rise to that one bad cell."

Cryo Electron Tomography: Unique Capability for Structural Biology Investigations

Cryo Electron Tomography: Unique Capability for Structural Biology InvestigationsCryo electron tomography's (CET) ability to visualize three dimensional biological structures - ranging in size from molecular to cellular - fills a critical gap between techniques with atomic resolution, such as x-ray diffraction (XRD) and nuclear magnetic resonance (NMR), and conventional light microscopy. However, it is CET's ability to investigate biological structures in their unperturbed, native context that makes it an indispensable tool in the currently exploding field of structural biology. more
