Machine learning and experimental tests of receiver bias identify signal components critical to correct species classification in guenons, linking face pattern diversity to selection for species discrimination.
Reconstruction of great auk population dynamics suggests that hunting pressure alone could have been responsible for their extinction, demonstrating that even abundant, widespread species can be vulnerable to intense exploitation.
The juxtacrine signaling molecule EphA7, when expressed on terminally-differentiated myocytes, non-cell-autonomously induces adjacent myoblasts to also commit to terminal differentiation leading to rapid coordinated differentiation across the entire population.
β3-AR signalling via cGMP in cardiomyocytes is regulated via phosphodiesterase 2 and 5 degradation, it is potentially cardioprotective, but dysregulated in heart failure through signal redistribution and higher phosphodiesterase activity.
Distinct regulation endows two isoforms of the transcription factor LIN-29 with distinct functions to achieve coordinated execution of separate juvenile-to-adult transition events in Caenorhabditis elegans..
