Science Friday Folgen

To mark Earth Day, we asked you to tell us about your favorite places on the planet. You took us to the woods near Traverse City, Michigan, to a lake in Oklahoma, to Long Island Harbor where you spent your summers as a kid.  Basking in a sea breeze and admiring a sunset are basic human pleasures. But how do you take these moments and turn them into meaning? How do you pin those feelings down with words?  Joining Host Flora Lichtman are two poets who make that attempt for their livelihood: Jane Hirshfield, founder of Poets for Science, and Kimberly Blaeser, founding director of Indigenous Nations Poets and former Wisconsin poet laureate. Guests:  Kimberly Blaeser is a poet, founding director of Indigenous Nations Poets, and former Wisconsin Poet Laureate. Jane Hirshfield is a poet, essayist, and translator. She is the author of “Ledger” (Knopf, 2020) and nine other books of poetry. She’s based in San Francisco, California. Transcripts for each episode are available within 1-3 days at sciencefriday.com.

What makes Earth special, and why are we here at all? In his book “Why Do We Exist?

He joins Host Flora Lichtman to celebrate our place in the cosmos.  Read an excerpt from "Why Do We Exist?" Guest:  Dr. Hakeem Oluseyi is an astrophysicist and author of “Why Do We Exist?

Nearly all Americans have some type of PFAS, commonly known as “forever chemicals,” in their blood. The chemicals, which are linked to numerous health issues, were first regulated in drinking water at the federal level two years ago (though some limits have been rolled back). But, back in 2018, New Jersey became the first state to adopt its own drinking water standards for PFAS. Now, researchers at Rutgers University have crunched the data to see how well it worked. They found that levels of the regulated chemicals dropped by as much as 55%.  Host Ira Flatow talks with the lead author of the study, cancer epidemiologist Hari Iyer about the significance of his findings and his plans to study the possible link between PFAS and prostate cancer.
