A change in social status can quickly lead to a change in the quality of the seminal fluid produced by a male Chinook salmon as he responds to increased reproductive competition from higher-status males.
Everyday soundscapes dynamically engage attention towards target sounds or salient ambient events, with both attentional forms engaging the same fronto-parietal network but in a push-pull competition for limited neural resources.
The gene Odd-paired is a late-acting regulator of zygotic gene expression, functioning coordinately with Zelda to influence chromatin accessibility and affecting genes expressed along both axes of Drosophila embryos.
Chronic engagement of Natural killer cell inhibitory receptors by MHC-I molecules maintains a high activity of the mTOR pathway allowing subsequent amplification of signaling through activating receptors upon acute stimulation.
ME31B is a general repressor of gene expression in the Drosophila early embryo, repressing translation before the maternal-to-zygotic transition and stimulating mRNA decay after activation of the zygotic genome.
