Brain model reveals how neural chaos is kept under control
A model of the brain’s visual cortex suggests how neural activity can remain highly variable without making perception unstable. Researchers found that mechanisms resembling excitation, inhibition and slower self-regulation can prevent tiny differences in initial brain activity from producing radically different outcomes.

Light pollution reshuffles predators and prey beneath the water
Even moderate artificial light that reaches the surface of a lake at night can change the distribution of predators and prey and disrupt the natural migrations of zooplankton. Limiting the light that reaches water bodies can help preserve natural relationships between aquatic organisms.
