Hierarchical super-structure identified by polarized light microscopy, electron microscopy and nanoindentation: Implications for the limits of biological control over the growth mode of abalone sea shells

Andreas S Schneider, Birgit Heiland, Nicolas J Peter, Christina Guth, Eduard Arzt, Ingrid M Weiss BMC Biophysics 2012, 5:19 (12 September 2012)

Abstract | Full text | PDF | PubMed |  Editor’s summary

The hierarchical super-structure of abalone mollusc shells can be revealed by conventional light microscopy methods, opening the potential to study shell growth mechanisms in vivo at high resolution.

Intracellular chemical gradients: morphing principle in bacteria

Robert G Endres BMC Biophysics 2012, 5:18 (7 September 2012)

Abstract | Full text | PDF | PubMed |  Editor’s summary

Robert Endres discusses a new study in BMC Biophysics that supports the emerging view that intracellular chemical gradients can exist in bacterial cells, and how these may limit in vitro analyses.
