The power of weak ties in gaining new employment
An experiment using data from 20 million LinkedIn profiles shows how much we rely on people we know less well to land new jobs.
Study reveals how environment and state are integrated to control behavior
A simple animal model shows how stimuli and states such as smells, stressors, and satiety converge in an olfactory neuron to guide food-seeking behavior.
Divorce is more common in albatross couples with shy males, study finds
In a long-studied population of wandering albatrosses, females are less likely to stick with a shy mate.
