The Delta variant now accounts for the vast majority of new COVID-19 infections in the United States. New models suggest the variant is driving a stark increase in daily case counts. Already, hospitals in some communities in Florida have matched their peaks from the days before the vaccines. The CDC has revised its guidelines about who needs to wear a mask and why. In this hour, we talk about what a Delta wave looks like, who is most at risk, and what’s different now as we mark 450 days of the pandemic. Learn more about your ad choices.

In 2018, science journalist Lynda Mapes drew international attention for her day-by-day coverage of the female orca known as "Tahlequah," who carried her dead newborn calf more than 1000 miles through the Salish Sea before finally letting her go. That reporting formed the basis for Mapes's newest book "Orca: Shared Waters, Shared Home," which explores the sophisticated social networks that orcas form and the environmental threats that are driving them to extinction.

Not much can beat sipping a coffee or drink from the cafe as you gaze over the SF skyline heading to work — or returning home — on one of the ferries that crisscross the San Francisco Bay. But the pandemic lockdown hit the ferries hard: From one day to the next, the Golden Gate Ferry went from operating six vessels a day, to two. In this hour, we get the latest on when ferry service will be restored to pre-pandemic levels, hear about new routes and plans for a “green fleet” and learn why ferries are key in a disaster.

To sweat is human. That’s according to science journalist Sarah Everts, whose new book “The Joy of Sweat” explores the biology of what she calls our “oddly flamboyant” way of controlling body temperature. We’ll hear why some of us are more profuse -- and smellier -- perspirers than others, what drives our cravings for sweaty workouts and hot soaks and why we still spend billions annually on products to hide the effects of our natural cooling system.

In the first retrospective of his work on the West Coast, SFMOMA’s current exhibition on electronic art pioneer Nam June Paik features more than 200 works from the artist whose five-decade career “changed the way we look at screens.” One of most acclaimed of the first generation of video artists, Paik’s early work in the 1960s changed perceptions of television, video and the boundary between art and spectator through its integration of camera, video, music and performance. We’ll talk about Paik’s work and legacy, and we’ll hear from contemporary video artists who will discuss Paik’s impact on their own art. Learn more about your ad choices.

For our inaugural Forum Book Club, we’ve picked Maceo Montoya’s “Preparatory Notes for Future Masterpieces.” The book interweaves its narrative with drawings and scholarly footnotes to tell the story of an aspiring painter with grand ambitions. This would-be artist faces several roadblocks: he is coming of age in 1940s New Mexico with no economic means to support his dreams and, instead of painting, he writes long notes for future works of art. Montoya takes readers along the narrator’s quest to become a celebrated artist — a journey that takes unusual turns including runs in with Chicanx historical figures such as activist Reies Lopez Tijerina and writer Oscar Zeta Acosta. In this comical and satirical tale, Montoya takes aim at what it means to tell a Chicano story, which Chicano narratives are elevated and who gets to become an artist. We’ll meet on the air to talk with Montoya and hear readers’ comments, reactions and questions. Learn more about your ad choices. Visit megaphone.fm/adchoices

Recent space flights by Jeff Bezos and Richard Branson have raised the tantalizing question of whether space travel is in our near future. Space exploration has traditionally been the venture of governments, but with last November’s launch of an astronaut crew to the International Space Station by Elon Musk’s company SpaceX, commercial flights to deep space seem more tangible. But is privatized space travel by billionaires just a vanity project? Or is this a huge step towards tackling space, the final frontier?   Learn more about your ad choices.

PG&E announced yesterday that it will bury power lines in high wildfire risk areas of California, amounting to 10,000 miles of lines, enough to reach about halfway around the earth. The utility says the plan would also eliminate the need to order power shutdowns during high fire risk events. We’ll talk with an expert about the advantages of underground power lines and what they cost. Learn more about your ad choices. Visit megaphone.fm/adchoices
