Decoding smell: Study reveals how odor signals shapeshift in the wind

CU Boulder researchers discovered that turbulent wind systematically reshapes odor signals as they travel, filtering some frequencies while creating new ones—patterns that animals like dogs and bees may use to navigate toward odor sources. The study, published in PRX Life, bridges physics and neuroscience to explain how animals decode complex, dynamic smell signals, with potential applications in search and rescue operations and detecting chemical leaks.
