Tiny skaters beneath the arctic ice rewrite the limits of life

Hidden within Arctic ice, diatoms are proving to be anything but dormant. New Stanford research shows these glass-walled algae glide through frozen channels at record-breaking subzero temperatures, powered by mucus-like ropes and molecular motors. Their astonishing resilience raises questions about how life adapts in extreme conditions and highlights the urgency of studying polar ecosystems before they vanish.
