Comment les coraux adaptent-ils les lois de la cristallographie?

Abstract:
Le squelette du corail rouge, qui prend des formes arborescentes variées, est constitué de briques élémentaires qui ne sont rien d'autres que des microcristaux de calcite magnésienne. Comment ces animaux gèrent-ils les lois de la cristallographie pour élaborer des formes aussi complexes ? Cette question qui relève du domaine de la biominéralisation connaît depuis quelques années un intérêt croissant du fait de nouveaux outils d'investigation, et du développement des recherches sur les matériaux biomimétiques et les nanoparticules. L'étude par microscopie électronique à balayage (MEB), diffraction d'électrons retrodiffusés (EBSD) et microscopie électronique à transmission (MET) du squelette du corail rouge de Méditerranée menée par une équipe du Centre Interdisciplinaire de Nanoscience de Marseille (CNRS, Universités d'aix marseille) associée à des chercheurs de l'Insitut de Ciencies del mar (Barcelone) et du California Institute of Technology (EU) permet de comprendre l'agencement des cristaux de calcite qui aboutit aux formes libres du corail. De nouveaux concepts de structures cristallines sont discutés dans cet article à paraître dans l'American Mineralogist.
