Scientists have discovered that fruit flies use a more sophisticated method than previously thought to track smells in turbulent air. Traditionally, it was believed that flies followed a simple “surge and cast” model, flying upwind when they detected an odor and moving side to side when they lost it. However, a team led by neuroscientist Vanessa Ruta at Rockefeller University found that flies have a more advanced way of navigating. They conducted experiments using a fly-sized treadmill, where flies were tethered over a floating ball in darkness. By controlling the direction and intensity of apple cider vinegar odors, researchers observed how flies responded to changing chemical landscapes. This study reveals the complexity of olfactory navigation in fruit flies, despite their tiny brains, and highlights the intricate ways animals interact with their environments.
