Single-molecule TIRF microscopy, biochemical assays and mathematical modeling demonstrate how actin-branch nucleation by the Arp2/3 complex is coordinately regulated by two biochemically distinct activators.
A chemical screen reveals that a compound used to treat a parasitic disease can trigger pluripotent stem cells to become neurons, uncovering a novel mechanism behind neuronal development.

The need for efficient pre-RNA splicing during early embryonic development of Drosophila indicates that the constraints imposed by the cell cycle are a force capable of driving changes in Eukaryotic gene architecture.
Zebrin-positive cerebellar Purkinje cells fire at lower frequencies than zebrin-negative cells, indicating that cerebellar circuits are not physiologically homogeneous.
Direct modification by endogenous peroxide of a conserved cysteine in the molecular chaperone BiP decouples its ATPase and peptide-binding activities, allowing for enhanced polypeptide holdase activity during oxidative stress.
An immune system pattern recognition receptor potentiates anti-tumor innate immune responses, offering new insight into anti-tumor activity of the innate immune system.
