Science Friday Folgen

During an electrical system test early in in the morning of April 26, 1986, Reactor 4 of the Chernobyl Nuclear Power Plant exploded. The disaster at the plant was not caused solely by the test, however—a perfect storm of engineering and design missteps, operational errors, and cultural problems all aligned to bring about the catastrophe. In his new book, Midnight In Chernobyl: The Untold Story of the World’s Greatest Nuclear Disaster, journalist Adam Higginbotham describes the events that led up to the meltdown, the dramatic, heroic, and perhaps futile attempts to lessen the extent of the accident, and the attempts by Soviet officials to contain the political ramifications of the explosion. He joins Ira to tell us more. Plus: Every vertebrate has red blood cells—that is, except for a small family of fish from the notothenoid family known collectively as “icefish.” These Antarctic-dwelling fish have translucent blood, white hearts, and have somehow adapted to live without red blood cells or hemoglobin. H. William Detrich, a professor of marine and environmental sciences at Northeastern University, explains how scientists are trying to decipher the secrets of the mysterious icefish. What’s more terrifying than becoming a new parent? Starting out as new parents in the Newborn Intensive Care Unit, where babies spend their first days entangled in wires attached to sensors that monitor their vital signs. But in the digital age, why must wires and sensors take up so much real estate on a tiny baby? That’s the question driving the development of a new monitoring device—a small wireless sensor that takes the scary “science experiment” effect out of the NICU, and gives parents more time to cuddle with their newborn. John Rogers, professor of material science and engineering and director of the Center for Biointegrated Electronics at Northwestern University, joins Ira to discuss how the new device could transform neonatal care in the U.S. and in developing nations around the world.   Subscribe to this podcast.

DNA is the universal programming language for life, and the specific code to that program are the combination of the base pairs adenine, guanine, cytosine and thymine. But are those the only base pairs that could be used to create DNA? Scientists looking into this question were able to create 4 different base pairs that don’t exist in nature. Chemist Floyd Romesberg, biologist Jef Boeke, and bioethicist Debra Mathews tell Ira how altered genomes could be used for creating novel medicines and fuels—and whether this is considered a new form of life. Plus: The climate is changing. Globally, of course. But also in Washington, where growing numbers of Republicans are jumping behind policies that would result in meaningful action on climate change. And yet, even as Congress appears ready to at least discuss the issue, and the government’s own scientists and military leaders sound louder alarms about the impending dangers of global climate change, the White House is assembling a group of climate change adversaries to counter those mainstream views. David Titley, a retired rear admiral who founded the Navy's task force on climate change, explains. Last year, China tightened standards for recycled materials it would accept, and now local recyclers nationwide find themselves struggling to find new homes for plastics, cardboard, and other materials that fell below par. Dana Bate, health and science reporter for WHYY, tells Ira how Philadelphia and its suburbs are handling the issue in the State of Science. And Sophie Bushwick, technology editor for Scientific American, explains how extreme climate change might cause stratocumulus clouds to disappear for good, and other top science news headlines, in this week's News Roundup.

The Science Friday Book Club discussion of N.K. Jemisin’s The Fifth Season may have stopped erupting for the season, but we have one more piece of volcanic goodness for you. SciFri producer and chief bookworm Christie Taylor got the chance to speak with Jemisin at our book club meet-up, “Voyage To The Volcanoes,” at Caveat in New York City. Listen for Jemisin’s adventures in volcano research, how real-world events inspired her to build an entire society around disaster preparedness, and how knowing your neighbors can be lifesaving. At the event, we also spoke to volcanologist Dr. Janine Krippner, who helped debunk volcano myths. And SciFri staffers Lauren J. Young and Johanna Mayer explained how history’s volcanic winters have influenced art (and religion) over the centuries. So, sit back and listen while you ponder what’s percolating deep in our planet—from quakes to shifting plates. Subscribe to this podcast.
