How long can ancient DNA survive, and how much stuff do we need to escape poverty?
Pushing ancient DNA past the Pleistocene, and linking agriculture to biodiversity and infectious disease
First up on this week’s show, Staff Writer Erik Stokstad brings a host of fascinating stories, from the arrival of deadly avian flu in the Galápagos to measuring the effect of earthworms on our daily bread. He and host Sarah Crespi start off the segment discussing just how much stuff you need to avoid abject poverty and why measuring this value can help us balance human needs against planetary sustainability.

Is ultrasound guidance a good option for peripheral intravenous cannulation in adults?
The intravenous administration of fluids and drugs, and the drawing of blood samples requires the placing of a catheter or cannula into a vein using a needle in a procedure known as peripheral intravenous cannulation. There are different ways to guide the procedure and a new Cochrane Review from December 2022 looks at the effect of using ultrasound guidance. In this podcast, Edoardo Ostinelli from the University of Oxford talks with lead author Masafumi Tada from Kyoto University in Japan, about the review. (Source: Podcasts from The Cochrane Library)

What are the most effective interventions during pregnancy for preventing stillbirth?
The Cochrane Pregnancy and Childbirth Group has done many reviews of interventions that might prevent stillbirth and, in December 2020, they brought these together in an overview. In this podcast, one of the Group ’s researchers, Dell Horey, talks with lead author Erika Ota, a professor at the St. Luke’s International University in Japan, about the findings.

Audio long-read: Thundercloud Project tackles a gamma-ray mystery
Researchers in Japan are trying to understand why thunderstorms fire out bursts of powerful radiation.Gamma rays – the highest-energy electromagnetic radiation in the universe – are typically created in extreme outer space environments like supernovae. But back in the 1980s and 1990s, physicists discovered a source of gamma rays much closer to home: thunderstorms here on Earth.Now, researchers in Japan are enlisting an army of citizen scientists to help understand the mysterious process going on inside storm clouds that leads to them creating extreme bursts of radiation.This is an audio version of our feature: Thunders...

How Hiroshima survivors helped form radiation safety rules, and a path to stop plastic pollution
Contributing Correspondent Dennis Normile talks about a long-term study involving the survivors of the Hiroshima and Nagasaki bombings. Seventy-five years after the United States dropped nuclear bombs on the two cities in Japan, survivors are still helping scientists learn about the effects of radiation exposure.
Also this week, Sarah talks with Winnie Lau, senior manager for preventing ocean plastics at Pew Charitable Trusts about her group’s paper about what it would take to seriously fight the flow of plastics into the environment.
This week’s episode was produced with help from Podigy.
