The retarding effect of a ribosome-bound internal ribosome entry site on eukaryotic protein synthesis is largely overcome following translocation of tripeptidyl-tRNA.

Phasic microfilament behaviors of the growth and stabilization of cortical actin caps are driven by distinct combinations of actin regulatory proteins, which display features of a deep competition for G-actin.

Spontaneous elongation of epithelial colonies is related to the orientation of the mean nematic cell elongation field, as shown and tested with experiments and theory.

Polarized assembly of cell-cell junctions drives Drosophila axis elongation.

Cylicin 1 and Cylicin 2 are essential components of the sperm perinuclear theca and their loss results in impaired spermiogenesis and thus in infertility in mice and men.

Polymerase θ is among the most proficient terminal transferases known and switches between three different mechanisms of terminal transferase activity.

Light signals adjusting the brain's daily clock induce distinct waveform changes in molecular clock gene rhythms at dawn and dusk, and trigger regionally differential clock changes.

Geometrical features of microtubule arrays regulate the collective activity of motor and non-motor proteins.

Structure-function analysis of the super elongation complex formed when HIV replicates inside cells reveals that the HIV-1 Tat protein binds to a cleft between P-TEFb, an enzyme that is involved in normal transcription, and AFF4, a protein that is used to build the super elongation complex

A variant of SELEX introduced here to induce abiotic evolution in a molecular system enables to observe and study speciation, the nature of fitness, and the interplay between use of resources and interactions between individuals.
