New research reveals how dread shapes decision-making
A new study reveals that people are far more emotionally affected by anticipating negative future outcomes than by imagining positive ones, helping to explain why many individuals avoid uncertainty and prefer decisions to be resolved sooner rather than later.

Aging zoo animals threaten long-term species conservation goals
Many mammal populations in European and North American zoos are aging—a trend that jeopardizes the long-term viability of so-called reserve populations and, with it, a core mission of modern zoos in global species conservation. This is the central finding of a new international
