We’ll talk with some of the pioneers in psychedelic research — from Amanda Feilding’s boundary-busting work to Robin Carhart-Harris’ theory of the "entropic brain."

2019 was an important year throughout the African diaspora — the 400th year since enslaved Africans first arrived in the United States. In Ghana — once the center of the European slave trade — 2019 was declared "the year of return" and the start of a campaign to encourage descendants of enslaved Africans to re-connect with the land of their ancestors.
