Body dissatisfaction, negative affect, and engagement in healthy behaviors: The conditional effect of future-self continuity.

The relationship between body dissatisfaction and negative affect is complex, with some research suggesting that this combination motivates individuals to engage in more health-related behaviors; while other studies find it increases unhealthy behavior. To bridge this gap, it may be the case that to the extent these individuals have continuity between their present and future selves, the more likely they are able to make positive health-related choices with this future self in mind. We examined individuals ( = 344; 51.

Variation of heavy metal concentrations (Ag, Cd, Co, Cu, Fe, Pb, V, and Zn) during the life cycle of the common cuttlefish Sepia officinalis.

The developmental changes in the concentration of 8 essential and non-essential heavy metals (Ag, Cd, Cu, Co, Fe, Pb, V, Zn) in the tissues (digestive gland, cuttlebone and whole animal) of the common cuttlefish Sepia officinalis collected in the bay of the river Seine were monitored from the end of the embryogenesis until the adult reproductive stage. Compared to embryos, juveniles after hatching displayed much higher concentrations of Ag, Cu, Fe and Zn, suggesting an efficient incorporation from seawater. Conversely, the amounts of Cd, Pb and V in hatchlings remained constant suggesting that these metals are barely bioavailable for juveniles.
