Extraembryonic tissue spreading in the scuttle fly Megaselia abdita requires mechanical decoupling from the underlying yolk sac.

The noninvasive visualization of dermal M1 and M2 macrophage phenotypes is shown for the first time in vivo.

The capacity to sustain effort to obtain rewards over time depends on the levels of the antioxidant glutathione in the nucleus accumbens - a brain region critical for motivated behavior - and can be boosted with a nutritional intervention (N-acetylcysteine).

The subjective time of social interactions reflects one's autistic-like tendency and is critically mediated by oxytocin, indicating that time perception is ingrained with personality traits, which likely have neuroendocrine origins as per previous research.

Complex and distributed plasticity processes are revealed by a functional and pharmacological analysis of visual habituation learning in larval zebrafish.

The genomic architecture of allopatric species is a mosaic of many conserved genes and a few adaptive ones, reflecting balance between conservation of ancestral functions and evolution of new features.

Social deficits in IRSp53/Baiap2-mutant mice accompany decreases in prefrontal neuronal firing variability, burst firing, and social information decoding accuracy, and memantine-dependent NMDAR inhibition, which rescues social deficits, alleviates burst firing, suggesting that burst firing links NMDAR dysfunction with social deficits.

The perception of time is influenced by movement environments, with slower movements associated with shorter perceived time intervals.

An expanded map of mouse cortex reveals the expansion of retinotopic organization into barrel and retrosplenial cortices.

Increasing adult-born neurons in the dentate gyrus reduces neuronal loss and chronic seizures in female mice using a mouse model of temporal lobe epilepsy.
