In the Review in this issue, B. A. Grzybowski et al. describe reaction-diffusion systems for intracellular transport and control. How do cells build, operate, and position structures for cell division, gradient sensing, signal transduction and amplification, and cell motility?
In a Highlight, T. B. Rauchfuss discusses the biosynthesis of the fastest natural hydrogenase.

In the Communications section, E. L. Chaikof et al. describe how to synthesize stable micellar structures from the self-assembly of diblock copolypeptides with cysteine residues at the diblock interface (see picture), thus affording a new class of protein nanoparticles.
N. Iwasawa et al. present a gold-catalyzed tandem cyclization of dienol silyl ethers to produce derivatives of bicyclo[4.3.0]nonane.
S. Mecking et al. succeeded in generating linear semicrystalline polyesters from plant fatty esters.
