This research investigates whether regeneration can be induced in animals that normally lack regenerative abilities. Using nutrient factors such as amino acids and insulin, regeneration was stimulated in mice, jellyfish, and fruit flies. The findings reveal that regeneration is a coordinated whole-body process involving energy allocation, organ remodeling, and conserved nutrient signaling pathways.

Fruit flies normally die from sleep loss due to lethal gut inflammation. But a mutant “fumin” fly, which sleeps very little, survives without inflammation. This research investigates how altered dopamine processing protects these flies, offering insight into why sleep is essential and how sleep loss contributes to disease.
