Colloids get complex
Article Abstract:
The term soft-matter denotes materials that are easily deformed by external stresses and encompasses liquid crystals, polymers, surfactants and colloids. Self-organization of soft-matter components can create complex and beautiful structures where their basic constituents have characteristic sizes of between several nanometers and several micrometers and crucially have the potential to self-organize, forming regular three-dimensional structures.

Mechanism limiting centrosome duplication to once per cell cycle
Article Abstract:
An in vitro system using Xenopus egg extract and purified centrioles in which both centriole and disengagement and centriole growth occur, are described. It is shown that centriole disengagement requires the protease separase at anaphase and that the disengagement licenses centriole duplication in the next cell cycle.

Insights into microtubule nucleation from the crystal structure of human gamma-tubulin
Article Abstract:
The 2.7-angstrom-crystal structure of human gamma-tubulin bound to GTP-gammaS is reported. The results revealed a curved conformation for gamma-tubulin-GTPgammaS, similar to that seen for GDP-bound, unpolymerized alpha beta-tubulin.
