    Why Your Brain’s Sense of Time Is So Elastic

    Our sense of time may be the scaffolding for all of our experience and behavior, but it is an unsteady and subjective one, expanding and contracting like an accordion.

    Reprinted with permission from Quanta Magazine‘s Abstractions blog. Ants, wasps, bees, and other social insects live in highly organized “eusocial” colonies where throngs of females forgo reproduction—usually viewed as the cornerstone of evolutionary fitness—to serve the needs of a few egg-laying queens and their offspring. How they got that way has been hard to explain despite more than 150 […]
