Ultraviolet radiation leads to secretion of an appetite-boosting hormone in male mice, but experts say it’s not yet clear whether the mechanism applies to humans.

The Scientist speaks with organismal biologist Xavier Glaudas about possible reasons for his recent finding that male Montpellier snakes cannibalize female conspecifics.

A study suggests that mutations in the gene that encodes the T1R1/T1R3 taste receptor allowed primates that relied on insects for protein to transition to eating leaves and fruit.

A study of 19 postmenopausal women found that eating a bar of chocolate in the morning affected their bodies differently than eating it at night, but neither led to weight gain.

The hormone, which is well known for regulating appetite, appears to influence neuronal development—a finding that could shed light on disorders such as autism that involve dysfunctional synapse formation.
