Ivory has been used since prehistorical times to produce objects with high symbolic value (figurines, beads, ornaments...) which therefore constitute important archaeological records of socio-cultural habits of past societies. By combining polarized light imaging, electron microscopy and X-ray scattering, the origin of the checkboard pattern visible on elephant ivory has now been elucidated.

In brain slices, resolving fast Ca2+ fluorescence signals from submicron structures is typically achieved using two-photon or confocal scanning microscopy, an approach that limits the number of scanned points.

Cancer cells are usually found to be softer than normal cells, but their stiffness changes when they are in contact with different environments because of mechanosensitivity. For example, they adhere to a given substrate by tuning their cytoskeleton, thus affecting their rheological properties.

Proteins are not fixed, they constantly change their conformation due to fluctuations in their energy landscape. Beyond a certain temperature, these dynamic changes of conformation are important, proteins undergo what is called a dynamic transition. This work examines the effect of pressure on this transition observed originally 30 years ago.

Cells are sensitive to their mechanical environment: pressure or shear can provoke biochemical responses. In order to accurately test the reaction of adherent cells to mechanical stimulations, we developed magneto-active substrates.
