Microtubule nucleation from the nuclear envelope in fission yeast involves repurposing of nuclear export proteins for a non-export-related function, docking cytoplasmic proteins at nuclear pore complexes.
Specific glutamylation of some α-tubulin isotypes affects kinesin-1 localization and transport processes that depend on it, but their absence can speed up transport, possibly explaining why some large cells express α-tubulin isotypes that are not glutamylated.
The crystal structure of bacterial RNA polymerase bound to the transcription bubble reveals key features that support the formation of a double-strand/single-strand DNA junction at the upstream edge of the −10 element where bubble formation initiates.
The crystal structure of Thermus transcription activation complexes containing the transcriptional activator CarD reveals a new mechanism for the activation of transcription.

A large-scale transcription factor screen reveals over twenty novel adipogenic regulators: most notably ZEB1, which exerts essential transcriptional control of fat cell differentiation.
The molecular mechanism behind how emetine inhibits the ribosome of the human malaria parasite, along with structural details of the complex formed, is revealed at high resolution using cryo-electron microscopy.

Early life adversity (ELA) accelerated PV+ interneuron development in BLA and delayed the ability of pre-adolescent mice to express, but not form, an auditory conditioned fear memory in childhood.
Bats' uniquely robust innate antiviral immune defenses select for faster transmitting viruses likely to generate extreme virulence upon spillover to secondary hosts with immune systems divergent from those of bat.
