Pheromonal communication in vertebrates
Article Abstract:
The diverse chemical nature of vertebrate pheromones and the advances in understanding the chemosensory systems and neural mechanisms underling such pheromonal effects are discussed. The studies using gene-targeted mice have displayed an unexpected diversity of chemosensory systems along with their underlying cellular and molecular mechanisms and future developments might show how the functions of the different chemosensory systems are integrated to regulate innate and learned behavioral and physiological responses to pheromones.

Calcium triggers exit meiosis II by targeting the APC/C inhibitor XErp1 for degradation
Article Abstract:
A demonstration that calcium-activated Catkin triggers exit from meiosis II by sensitizing the anaphase-promoting complex/cyclosome (APC/C) inhibitor XErp1 for polo-like kinase 1 (plx1)-dependent degradation is presented. Phosphorylation of XErp1 by calmodulin-dependent protein kinase II (CaMKII) leads to the recruitment of plx1 that in turn triggers the destruction of XErp1 by phosphorylating a site known to serve as a phosphorylation-dependent degradation signal.

Weak pairwise correlations imply strongly correlated network states in a neural population
Article Abstract:
Weak correlations between pairs of neurons coexist with strong collective behaviour in the vertebrate retina in the response of ten or more neurons. It is found that this collective behaviour is described quantitatively by model that captures the observed pairwise correlations but assume no higher-order interactions.
