Psilocybin shows context-dependent effects on social behavior and inflammation in female mice modeling anorexia

Researchers found that psilocybin reduced novelty-seeking in control mice, but heightened it in anorexia model mice. Inflammation levels were also altered, contradicting expectations based on human studies. The study's findings have implications for understanding anorexia nervosa and the potential therapeutic effects of psychedelics.

The environment shapes the organization of ant societies

Research reveals three major types of ant societies: small colonies with a single queen and diverse workers in tropical regions, large colonies with multiple queens and uniform workers in deserts, and temperate regions with polygynous and monomorphic colonies. Environmental conditions shape these social structures on a global scale.
