Plant Development: Should I Stop or Should I Grow?

Plant Development: Should I Stop or Should I Grow?

Plant growth is tightly controlled through the integration of environmental cues with the physiological status of the seedling. A recent study now proposes a model explaining how the plant hormone ethylene triggers opposite growth responses depending on the light environment.

Should I Stay or Should I Go

This paper considers migration as an investment decision. It develops a continuoustime stochastic model to explain the optimal timing of migration, in the presence of ongoing uncertainty over wage differentials. The results show that individuals prefer to wait before migrating, even if the present value of the wage differential is positive, because of the uncertainty and the sunk costs associat...

Should I stay or should I go?

In this issue of Neuron, Lee et al. (2016) assessed the brain-wide effects of stimulating the direct and indirect pathway by optogenetic activation of D1 and D2 striatal neurons. This work demonstrates the exquisite power of combining cell-type-specific perturbation methods with focal and whole-brain measurements of brain activity.

Should I Stay or Should I Go?

Data from a longitudinal study of older adults in an upstate New York county (N = 333) show that poor housing “fit” increases the likelihood that older adults are currently considering a move, as does lower residential satisfaction. Those adults who said only that they “might consider moving” focused on health transitions that might signal a need for a new housing situation. Residential satisfa...
