Shielding astronauts from cosmic rays, and planning the end of fossil fuels
Science Magazine PodcastShow Notes
First up on the podcast, how do we protect astronauts when they leave the shelter of Earth’s protective magnetic fields and face the slow, constant bombardment of space radiation? Freelance science journalist Elie Dolgin joins host Sarah Crespi to discuss what we know about the damage from high-velocity particles and the research being done to curb their biological toll.
Next on the show, modeling the fall of fossil fuels during the decarbonization of energy systems, with civil engineer and environmental sociologist Emily Grubert and historian and engineer Joshua Lappen, both at the University of Notre Dame. The pair wrote a policy forum on predicting chokepoints or “minimum viable scales” in the decline of fossil fuel networks—in effect, when a system might get too small to maintain its function. Understanding how to keep things online until they are no longer needed is important to maintain energy for all, as renewables grow and mines, pipelines, and refineries shrink.

A newly resurfaced photo taken by Rosalind Franklin—photo 49—shows she was aware of the helical structure of DNA and explains why her published image—photo 51—does not have indications of her understanding of its shape.
First up on the podcast, producer Meagan Cantwell and Newsletter Editor Christie Wilcox discuss a few stories from ScienceAdviser, including why Nazi Germany was unlikely to ever make an atomic bomb, a gene that might prevent gray hairs, and 140 years of cheese history from a Swiss basement.
First up on the podcast, freelance science journalist Robin George Andrews describes Japan’s upcoming Martian Moons eXploration mission that will nab a sample from the surface of Mars’s moon Phobos. The material, due back to Earth in 2031, could reveal the origins of this mysterious moon, the past habitability of Mars, or even hints of life itself.
