Genetic screens and functional assays utilizing reporter mRNAs triggering NGD or COMD provide a basis for understanding the unique contributions of each pathway to translation-coupled mRNA decay and contextualizes their effects in the larger cellular process of translation surveillance.
As Caenorhabditis elegans adult hermaphrodite germ cells leave the stem cell niche, they associate with a pair of somatic gonad cells that were thought to be symmetrical, but that actually take on dramatically different positions in the organ.
The structure of the yeast RSC complex, a member of the SWI/SNF chromatin remodeling family, determined by cryo-electron microscopy, reveals a conserved structural core and the mode of nucleosome engagement.

Drosophila synaptotagmin 7 functions to restrict SV availability and release, but does not act as the Ca2+ sensor mediating the asynchronous release and facilitation remaining in synaptotagmin 1 mutants.
A previously undetected dynamic cell structure orients the mitotic spindle of germ stem cells and grows over one daughter cell, thus helping to balance niche retention with niche exit.
Single synaptic vesicle imaging shows that kinetically distinct endocytic pathways are differentially regulated by calcium and temperature, and influence the fidelity of synaptic vesicle protein retrieval.
