White fat cells (adipocytes) activate the lipolysis pathway to produce the free fatty acids that are used as heating fuel by brown adipose tissue. Nayak et al show that OPN3 is required for blue-light-enhanced activation of the lipolysis pathway. This explains the low body temperature of OPN3 mutant mice.
