A novel experiment shows that ocean acidification decreases freeze tolerance in blue mussels, which may limit their ability to redistribute poleward in response to climate warming.

Experiments reveal mechanisms through which Caenorhabditis elegans zygotes depleted of Aurora A or lacking centrosomes spontaneously establish two posterior PAR-2 domains, one at each pole, in a curvature-dependent manner.

Tubulin engages unique lateral interactions without longitudinal ones during microtubule polymerization, leaving holes of a few subunits size potentially at the origin of tubulin exchange within their shaft.

A combination of genetics, behavior and physiology demonstrate that cool and moisture sensing rely on overlapping combinations of sensory receptors in Drosophila.
Unique heterochrony in the cranial segments in bichirs triggers the early formation of their external gills, and might be informative about developmental mechanisms facilitating increased breathing capacity.
Recordings from serotonin-producing neurons in the brain reveal that these neurons are highly activated by sudden changes in previously familiar environments, potentially explaining why serotonin is important for learning to adapt to such changes.
A minimal cell-like system with defined geometry has been used to investigate the establishment and spatial control of a protein gradient that positions the bacterial cell division machinery.

A digital flesh model of the sail-backed dinosaur Spinosaurus was tested and performed very poorly in water, favoring the view of this dinosaur as a two-legged, wading ambush predator of large fish in shallow waterways and not an aquatic dinosaur.
Cytonemes mediate, and are essential for, Wingless signaling from the Drosophila wing disc to disc-associated myoblasts and for Delta-Notch signaling from these myoblasts to the dorsal air sac primordium.
