Nick talks to genetics researcher & writer Razib Khan. Razib did graduate work in genetics at the University of California-Davis and recently founded a genomics data startup. He also runs a Substack, "Unsupervised Learning," where he write a lot of fascinating articles, usually on the subjects of human evolutionary & population genetics, personal genomics, and more. Nick and Razib discussed: how the story of human evolution has changed over the past two decades; genomics technology & ancient DNA; Neanderthals, Denisovans & ancient humans; personal genomics (e.g. 23AndMe, Ancestry.com); Razib's experience as a writer on Substack.

Nick talks to Christian Luscher, MD, PhD, a neuroscientist at the University of Geneva whose lab studies the cellular mechanisms that underlie drug reinforcement, dependence and addiction. Dr. Luscher talks about the nature of addictive drugs in the brain, how ketamine works, and the latest research from his lab look at how ketamine's unique effects within the brain's reward circuitry enable it to be psychoactive & reinforcing, but have a very low addiction liability (in rodents). He also discusses what this research may mean for the use of ketamine as a therapeutic treatment for depression in humans. LEARN MORE & SPPURT M&M: All M&M content is available on Substack.

Nick talks to anthropologist Dr. Michael Winkelman, who was a professor at Arizona State University for many years, where he studied topics related to shamanism as practiced by early hunter gatherer societies, and other topics related to human cultural evolution. He is now retired and conducts independent research from Brazil, where he now lives. They discuss: what shamanism is & the core features of shamanic ritual practices across historical hunter gatherer cultures; how the various ritual practices associated with shamanism were used by forager societies (e.g. symbolism, group dance and drumming) & the use of psychedelics; evolution of shamanism & religion from prehistoric times to the present; role religion and spiritual practices have played in human evolution; how human culture is akin to virtual reality & how human ritual practices help sculpt the narratives that form within human cultures that regulate human behavior; future of religion & spirituality in the modern age & whether the use of psychedelics as entheogenic substances might have a role to play in that.

Nick talks to Dr. David Cohen, a professor at the UCLA Luskin School of Public Affairs. His research looks at psychoactive drugs (prescribed, licit, and illicit) and their desirable and undesirable effects as socio-cultural phenomena “constructed” through language, policy, attitudes, and social interactions. They discuss: prescription psychiatric drugs, including SSRIs, benzodiazepines and stimulants (e.g. Adderall); the history of how some of the most widely prescribed psychiatric drugs came to be so popular; how pharmaceutical companies go about marketing these drugs and the conditions they aim to treat to both physicians and the public; the quality of the evidence supporting their use; what we are learning about the potential for dependency, long-term health effects, and actual level of benefit that comes from chronic psychiatric drug use; why many psychiatric drugs are increasingly prescribed in combination; and more.
