We’re in the midst of the largest vaccine rollout of our lives. A turning point, we hope. But it’s complicated — medically, logistically, philosophically. Who will get it first? Will it work? And, as a new variant of the virus emerges, will we get it in time? We decided to take you behind the scenes, talking with people who volunteered for trials, and to those scientists and reporters who trace every part of our search for immunity.

Not everyone has a nice, big yard to stretch out in while sheltering in place from COVID-19. But maybe you don't need one. People are using virtual spaces to live out the real experiences they miss — like coffee shops, road trips, even building your own house on a deserted island, or Walden Pond. In a world where we're mostly confined to our homes and Zoom screens, does the line between virtual and real-life space mean much anymore?

We’ve all been changed by the experience of living through a pandemic. We figured out how to sanitize groceries, mute ourselves on Zoom and keep from killing our roommates. But we’re also tackling bigger, existential questions — how can we, individually and collectively, find meaning in the experience of this pandemic?

Over the past decade, plant scientists have quietly transformed the way we think of trees, forests and plants. They discovered that trees communicate through vast underground networks, that plants learn and remember. If plants are intelligent beings, how should we relate to them? Do they have a place in our moral universe? Should they have rights?

Human identity cannot be separated from our nonhuman kin. From forest ecology to the human microbiome, emerging research suggests that being human is a complicated journey made possible only by the good graces of our many companions. In partnership with the Center for Humans and Nature and with support from the Kalliopeia Foundation, To The Best Of Our Knowledge is exploring this theme of "kinship" in a special radio series.

Before the time of commercial flights and road trips, we traveled to far off places without taking a single step. All you had to do was open a book. From Africa to England, to a kamikaze cockpit, and to realms of fantasy. Books aren’t just books. They’re passports to anywhere.
