Out breeding depression in Caenorhabditis tropicalis is due to common maternal-offspring incompatibilities that interact with a highly heterogeneous genetic background and may provide a short-term advantage to inbreeding.
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.
The arcuate nucleus kisspeptin neurons express multiple transmitters but use only the neuropeptide kisspeptin to drive the episodic secretion of gonadotropin-releasing hormone.

During perceptual decision-making, some errors on easy decisions (lapses) are not simply mistakes, but instead reflect strategic decisions to explore actions associated with uncertain rewards.
Temperature-dependent fasciation mutants of Arabidopsis unexpectedly connect mitochondrial RNA processing to the control of cell proliferation during lateral root morphogenesis via electron transport chain activity and reactive oxygen species production.
