Notes

  • Scientists identified previously unknown hair-like structures on beagles' tongues.
  • These structures facilitate the rapid spreading and evaporation of saliva, aiding in canine thermoregulation.
  • BioCCS is a new material developed based on the mechanism of canine tongue structures.
  • BioCCS surface features microscopic grooves to enable rapid liquid distribution.
  • Nanowires embedded within the grooves of BioCCS weaken intermolecular bonds in water, enhancing evaporation rates.
  • The technology is designed for cooling applications in electronics.

Part of a longer story

This is day 2 of 2 in Development of Bio-inspired Cooling Technologies, which has been running since 2 August 2026. Reading it whole is usually worth more than reading today alone — the exam asks how something developed.
