This research investigates how Melatonin regulates sleep using zebrafish models. The work identifies the MT1 receptor as essential for melatonin-induced sleep and suggests melatonin may reduce responsiveness to visual stimuli during sleep, helping explain how the brain increases arousal thresholds and maintains nighttime sleep states.

Antifreeze chemicals are toxic. This research tests new ice-recrystallization inhibitors that enter embryos easily, cause minimal developmental effects, and prevent damaging ice-crystal growth. These findings could enable long-term genetic preservation and support future ecosystem restoration.
