Tripping Hard For Science
Episode of
Nerdette
What’s it like to give people hallucinogenic drugs and study what happens? How might these drugs be used for therapy? And what causes people to take drugs in the first place? That’s what we asked Harriet de Wit, who runs the University of Chicago’s Human Behavioral Pharmacology Laboratory, where she administers drugs like LSD, ecstacy and psilocybin to volunteers in an effort to learn more about the human nervous system. “The whole world of researchers is feeling very cautious,” de Wit tells us, “cautiously optimistic — that if the drugs are used under controlled circumstances, they might have some potential benefits.”Let’s get funky.

Greta gives 'Booksmart' four out of four Gretas, a new rating system we've devised specifically for this wonderful new movie. Why's it so good? Well, it’s smart, funny, a little raunchy, and it embraces so many gorgeous, gut-wrenching elements of what it means to be a smart, funny teenage girl. This week on Nerdette, we talk with the wonderful Kaitlyn Dever and Beanie Feldstein (the stars of the film) about the movie's themes: Friendship, growing older, sexuality, feminism, and dealing with high expectations. Bottom line: GO SEE IT.

De-Extinction: How, Why, And What If?
Episode of
Nerdette
Scientists around the world are trying to figure out how to mitigate the potentially disastrous impacts of climate change. Among the innovative ideas? De-extinction. “De-extinction is a scientific movement that’s aiming to recreate close versions of extinct species,” said Britt Wray, the author of Rise of the Necrofauna: The Science, Ethics, and Risks of De-Extinction. Wray says the idea is to create close facsimiles of “keystone species,” or animals that had a profound impact on their ecosystems. As you can imagine, de-extinction brings up a lot of questions, including: How on earth do you replicate an ancient zebra-horse? What happens when countries can create patents for lab-grown animals? And why would we want woolly mammoths to roam the arctic again? Wray tackles all those questions, and more, on the latest episode of Nerdette.
