First evidence of cohesin folding occurring in vivo and during cohesion together with a detailed description of the structural aspects of cohesin's elbow folding through a series of novel structures.

The helical bacterium Helicobacter pylori patterns cell wall synthesis using two distinct cytoskeletal proteins, CcmA and MreB, to achieve its characteristic shape.

Rheological properties of the environment regulate sperm swimming and navigational behavior through suppression or reactivation of sperm rolling around its longitudinal axis.

Salamanders originate as metamorphosed with a biphasic lifestyle as shown by the palate shape and several non-shape features associated with the vomerine teeth, with diverse ecological types displayed in living species achieved in the Early Cretaceous.

Low-field single-sided magnetic resonance diffusion methods detect and measure permeability of sub-micron compartments which likely include cell processes, organelles, and cellular vesicles within ex vivo mouse spinal cords.

Naturalistic animal behavior exhibits a complex organization in the temporal domain, whose variability stems from hierarchical, contextual, and stochastic sources and can be naturally explained in terms of metastable attractor models.

Dynamic dopaminergic signaling modulates the timing of reward-related movements by tuning the moment-to-moment probability of their onset.

Simultaneous quantification of each of the main motor programs in the roundworm C. elegans yields new insights into the neural mechanisms that coordinate animal behavior.

For initiation of cell-wall insertion, the cross-linking enzyme PBP2 stably binds to a component of the cell envelope that is different from MreB filaments.

Sex-specific characteristics of the fruit fly courtship behavior are not specified by a single binary switch, but as a combination of traits that are modularly specified by separable genetic switches.
