Fruit flies reset their internal clock by actively changing their surroundings

Fruit flies can regain rhythmic behavior in constant light conditions, demonstrating a preference for structured daily patterns.

• Constant illumination disrupts the circadian clock in fruit flies, leading to uncoordinated movement.
• Flies exposed to both dark and illuminated areas in constant light showed the ability to restore rhythmic behavior.
• The restored rhythms were linked to molecular changes in neurons that regulate behavior.
• Improved sleep quality was observed in rhythmic flies compared to those with disrupted rhythms.
