Tight junctions (blue dots) between cells are connected areas of the plasma membrane that stitch cells together. Adherens junctions (red dots) join the actin filaments of neighboring cells together.

UNIGE scientists have revealed the key role played by a form of actin in the mechanics of epithelial membranes and the dynamics of components of cell-cell junctions.

A solar cell is made of two types of semiconductors ... of positively charged holes (which are vacancies due to the lack of valence electrons). Near the junction of the two layers, the electrons on ...
