Brain imaging and behavioral analysis reveal two opposing states of hunger, represented by anti-correlated lateral and caudal hypothalamic dynamics that are important for the homeostatic control of feeding in zebrafish.
The cAMP-dependent protein kinase A controls the switch from actively sprouting new blood vessel formation to vessel quiescence by reducing endothelial autophagy through phosphorylation-mediated destabilisation of ATG16L1.
MmuPV1, a papillomavirus that infects laboratory mice (Mus musculus), is discovered to be sexually transmitted, providing a new animal virus model to study sexually transmitted human papillomaviruses (HPVs).
Grid cells lose their hexagonality during hippocampal inactivation, but maintain temporal and spatial synchrony between pairs of cells, implying that hippocampus does not determine phase relations between grid cells.
The histone modification H3K9me2 marks peripheral heterochromatin and ensures positional information is safeguarded through cell division such that individual lamina-associated domains are re-established at the nuclear periphery in daughter nuclei.
