Today, we’re featuring the audio version of California magazine’s recent cover story, “Into the Ishi Wilderness.” In 1911, a Yahi Native American man walked out of the wilderness near Oroville, California.

Geneticists are exploring de-extincting extinct and near-extinct species, but ethical and logistical problems abound. Laura and Leah sit down with a genetic engineer and an ecologist from UC Berkeley to understand how de-extinction works and the unintended consequences of playing god. Life, uh, finds a way.Support the show

Since the first human left Earth’s atmosphere in 1961, few earthlings—and even fewer private citizens—have had the opportunity to “boldly go” there. But, with new advancements from SpaceX, Blue Origin, and other spaceflight companies, wealthy tourists could soon be booking rooms in hotels in outer space. As with any new industry, the rise of space tourism raises some new, sometimes uncomfortable, questions: Are we colonizing space? Is this just another exclusive vacation experience for the ultra-rich? Why are billionaires spending so much money on space tourism when there are plenty of humans on Earth without food, housing, or health insurance? Laura and Leah speak with two UC Berkeley grads, including the fifth-ever space tourist and one of the minds behind the universe’s first space hotel.Support the show

Five years after 29-year-old, terminally ill Brittany Maynard makes national news by choosing to end her life early, medically assisted death continues to face enormous legal and social barriers. And yet public support of the practice is high. As life-expectancy and palliative care improve, we face new questions: Under what circumstances are people allowed to choose when and how they die? And how might rethinking the conversation and practices around death change our very conception of it? To find out, Laura and Leah speak with California’s leading end-of-life doctor and a healthy octogenarian who plans to quit while she’s ahead.Support the show
