Engineers and biologists have found that #bird feathers act like specialized heat sinks that shed infrared radiation through the #atmosphere.Species living in open #grasslands are especially effective at using this method to stay cool under the #sun. The finding could help researchers design new materials for passive cooling in human #buildings. https://www.sciencealert.com/bird-feathers-may-shed-heat-into-space-engineers-explain#birds #physics #engineering #nature #science #biology #evolution #thermodynamics #ornithology #biomimicry
