Science Friday

Scientists studying climate models say there’s a high chance this will be an El Niño year—and that we could be in for a “super” El Niño. The difference is indicated by sea surface temperatures in part of the Pacific Ocean rising a little—or a lot—above their long-term average.

El Niño is one half of what climatologists call the ENSO, the El Niño-Southern Oscillation. The oscillation operates on a roughly 3-7 year cycle, changing the path of the jet stream and shifting weather conditions around the world. An El Niño year, for instance, typically brings wetter weather in the western U.S. but dryer conditions in the Pacific Northwest, and can be a drought buster for regions such as southern California.  But shifting ocean currents also have the potential to affect marine ecosystems, leading to algal booms, coral bleaching, and more.  

Climate scientist Dillon Amaya joins Host Ira Flatow to describe the role of the El Niño in shaping world weather, and what effects a particularly strong El Niño year might have on global ecosystems.

Guest: 

Dr. Dillon Amaya is a research scientist at the NOAA Physical Sciences Laboratory in Boulder, Colorado.

In April, the crew of Artemis II got an unprecedented tour of the far side of the moon, and they brought back a proverbial shoebox full of pictures. Lunar scientist Kelsey Young stayed on Earth, and helped guide the astronauts through their photo shoots from Mission Control.

Young talks with Host Flora Lichtman about how the science team chose their shot list, how to lead distant astronauts in their scientific observations, and what researchers are learning from the images and in-the-moment descriptions captured by the Artemis II crew.

Guest: 

Dr. Kelsey Young is the Artemis science flight operations lead for NASA's Science Mission Directorate.

When Kemi Doll was in medical school, she learned that Black women are twice as likely to die from uterine cancer as white women, and also suffer disproportionately from other uterine-related conditions. What wasn’t explained was why. Now a gynecologic oncologist, Doll has made it her mission to change these trends and improve care for Black women. 

She joins Flora to discuss her new book, “A Terrible Strength: The Hidden Crisis of the Black Womb and Your Survival Guide to Healing.” They explore the way systemic racism and the normalization of Black women’s pain lead to later diagnoses of uterine cancer and poorer health outcomes for a range of gynecologic conditions including fibroids, endometriosis, and heavy periods. And Doll explains the problem with using reproductive health as a synonym for uterine health. 

Guest: 

Dr. Kemi Doll is a gynecologic oncologist and professor at the University of Washington Schools of Medicine and Public Health.

Breaking news out of eastern Oklahoma! A hole in the sky has opened. Through it, an unidentified turtle-shaped craft has descended. Alerts say that this is first contact. 

So it goes in the sci-fi thriller “Hole in the Sky.” In the book, author Daniel H. Wilson imagines this moment where we meet alien life for the first time. It’s set in the heart of Cherokee Nation and follows characters including a military man, a NASA scientist, and a Cherokee father named Jim who is just trying to survive the alien entity.

Wilson joins Flora for a conversation about the book and how he integrated elements of Cherokee culture with science fiction. They get into the ways we project our own fears—like genocide and slavery—onto aliens, and how science fiction helps us imagine the unimaginable. 

The SciFri Book Club is reading “Hole in the Sky” during May and June. Join us to read along! 

Read an excerpt from “Hole in the Sky.”

Guest: 

Dr. Daniel H. Wilson is a Cherokee citizen and bestselling author of “Robopocalypse,” “Hole in the Sky,” and several other books. He holds advanced degrees in machine learning and robotics and lives in Portland, Oregon.
