Psychedelics are evolutionarily ancient compounds produced by fungi, plants, and microbes. Humans also synthesize psychedelics. Researchers want to know how and why.

Steven Barker is on a forty-seven-year-long journey to understand the mind-blowing science of psychedelics.

The antidepressant properties of hallucinogenic drugs may stem from their ability to bind to intracellular serotonin receptors, a study suggests.
