How fruit flies switch their body clock into winter survival mode
Researchers at Washington State University have discovered that fruit flies undergo genetic 'alternative splicing' to adapt their biological clocks for winter survival. This process shuts down reproductive systems and lowers activity levels, providing insights into seasonal biological changes.
Why it matters
Understanding these genetic mechanisms could lead to new methods for controlling agricultural pests and improving human health research related to seasonal cycles.
Scientists studying how animals survive the winter have discovered that fruit flies completely rebuild their internal biological clocks to switch into a separate seasonal mode. For context, a fruit fly is a tiny insect that feeds on ripe, rotting, or fermenting fruits and vegetables. They are usually about 2–4 millimeters long, have tan or yellowish-brown bodies, red eyes, and clear wings.There are two common ways people use the term: Household fruit flies and laboratory fruit fliesThe discovery reveals a genetic winter lock that keeps the insects in a low-activity state until warm weather returns. Led by researchers at Washington State University, the study found that the biological clock does not simply run slower in cold weather.
