The interaction between the sperm hook and the female reproductive tract, including various sperm dynamics related to their movement through the reproductive tract, has been directly observed for the first time using deep tissue live imaging.
A novel 2D-to-3D human brain organoid protocol reveals the pivotal role of FGF8 signaling in driving regional patterning and cellular diversity, while also modulating genes crucial for both normal and pathological neural development.
During zebrafish embryogenesis, dact1 and dact2 are necessary for axis lengthening and craniofacial morphogenesis, and the protease capn8 is misexpressed in dact1/2 mutants.
An analysis of vestibular projection neurons lacking their motor neuron partners resolves outstanding controversies for whether and how motor neurons shape vestibulo-ocular reflex circuit assembly.
A member of the Inhibitor of DNA-binding (Id) gene family, best known as negative regulators of tissue-specific master regulatory bHLH transcription factors, also suppresses non-apoptotic caspase activities.
New research shows that the neural circuit responsible for stabilising gaze can develop in the absence of motor neurons, contrary to a long-standing model in the field.

The double helix actin network surrounding the mitochondrial sheath of the sperm midpiece undergoes structural changes prior to the motility cessation during sperm-egg fusion.
Abolishing opposing hair cell orientation in mouse otolith and zebrafish neuromast organs preserves segregation of afferent innervation but affects zebrafish mechanotransduction and mouse vestibular reflexes.
