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.

The acoustic representation of the outside world in the midbrain of a bat becomes more precise as it uses double clicks to locate closer objects.

Bioinformatics and experimental approaches identify families of membrane proteins requiring the co-ordinated action of the Sec pathway and Tat pathways for their integration and define features of the polypeptides that mediate interaction with these pathways.

Single episodes of voluntary exercise induced a functional increase in hippocampal synapses mediated by activity-dependent expression of the BAR protein Mtss1L, acting as a novel early effector of synapse formation.

Dimers of Bak assemble into clusters without using a distinct protein-protein interface, which may explain the apparent difficulties in obtaining high resolution structures of the pore complex and in targeting dimer-dimer interactions to regulate apoptosis.

Evolutionary bioinformatics and experimentation are applied to the components of the Tat protein transport system to elucidate the structure of the membrane-bound receptor complex and to deduce a molecular description for its substrate-triggered activation.

Some species of bats hunt for insects that are resting on surfaces by detecting interruptions in the echoes from that surface, suggesting that resting on rough surfaces may help insects to evade detection by echolocation.

Correlative microscopy and electron cryo-tomography on apoptotic HeLa cells reveal remodeling of outer and inner mitochondrial membranes, Bax cluster ultrastructure and ATP synthase reorganization in ruptured mitochondria.

Measurements of bar-headed geese flying in a wind tunnel in hypoxia reveal that these birds sustain aerobic flight at high altitude via a reduction in metabolism.

The Fat-regulated scaffolding protein Dlish controls the activity, levels and cortical localization of Warts-inhibiting myosin Dachs by linking Dachs to a critical Dachs regulator, the DHHC palmitoyltransferase Approximated, and to the Fat-mediated regulation of Dachs stability.
