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.

Malaria parasites have simplified and adapted their mitochondrial metabolism to lack fatty acid synthesis but retain an unusual acyl carrier protein required for stability of the core iron-sulfur cluster biogenesis complex.

Mechanically induced injury of zebrafish lateral-line organs shares key features of damage observed in noise-exposed mammalian ears, such as inflammation and synapse loss, yet, unlike mammals, rapidly repairs following damage.

RTN3 is upregulated upon RNA viral infection, in turn suppresses antiviral responses by impairing TRIM25-mediated RIG-I K63-linked polyubiquitination and decreases neutrophil populations and inflammatory infiltration, representing a novel inflammatory resolution.

The nutrient composition of food alters both the size of gut epithelial cells and the ability of the stem cell niche to control tissue turnover, resulting in changes in size at the organ level.

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

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.
