Studying locusts in virtual reality challenges models of collective behavior

A recent VR study on locusts' navigation challenges classical models of collective swarming behavior, revealing internal cognitive decision-making processes. The findings suggest that locusts do not follow fixed interaction rules as previously thought, but instead respond to their sensory environment with probabilistic decision-making.

Prevalence and control of diabetes among US adults

The study found that the prevalence of adults with diabetes did not significantly change between 2013 and 2023. However, glycemic control among those with diagnosed disease worsened, particularly among young adults. This trend is concerning due to its potential impact on lifetime risk of cardiovascular events.

Scientists discover key protein in resilience to stress

A study published in Nature Neuroscience found that overexpressing cannabinoid receptor type 1 (CB1) in astrocytes promotes resilience to chronic social stress by reducing anxiety levels and depressive symptoms. The researchers also discovered an association between CB1 receptors and depressive symptoms in human brains.
