    At the Bottom of the Bottom of the World

    As we in North America emerge from a remarkably mild winter, the brief and sunny summer in the world’s deep south is drawing to a rapid close. Antarctica’s days are becoming shorter, and come the vernal equinox the South Pole will enter into its yearly hibernation—six months of dusk and night. Researchers from Columbia University…
