Pre-hematopoietic stem cells emerge from the aortic floor according to two radically different morphodynamics whose biomechanics rely on controlling apicobasal polarity in hemogenic precursors, which may impact on their fate.

A subset of genes in the mouse brain show dynamically regulated and unequal expression of maternally and paternally derived variants, with implications for brain development and function.

After a movement, the final posture of the arm is stabilized by a subcortical structure that mathematically integrates movement commands over time.

The genomes of animal progenitors evolved as mosaics of old, new, rearranged, and repurposed protein domains, genes and pathways and paved the way for the origin and evolution of animals.

High-speed calcium imaging from the axon initial segment shows that sodium channels are in part permeable to calcium ions.

A fly's locomotion can be decomposed into a small number of locomotor features which can be modulated by odors and other sensory information.

Models that generate tandem alignments of cell polarities are more readily compatible with the formation of PIN1 polarity patterns in plant leaf buds than the most widely accepted “up-the-gradient” model.

A three-dimensional description of the cytoskeletal arrangement, cytoplasmic flows, and cargo transport in stage 9 Drosophila oocytes accurately reproduces mRNA localizations in wild-type and mutant oocytes.

Intersectional genetics show that excitatory neurons are essential for the functional and anatomical maturation of cerebellar circuits in mice.

Across five experiments, Eurasian jays’ caching behaviour provides little evidence of the ability to integrate cues about a potential pilferer’s visual perspective and desire and, challenging previous findings, to respond to either of the two social cues independently.
