Summary

To study the biological differences brought on by space travel, NASA sent one twin into space and kept another on Earth in 2015. Now, researchers from that project are trying to replicate that work planet-side to see whether the differences in gene expression were due to extreme stress or were specific to being in space. Sarah Crespi talks with Online News Editor Catherine Matacic about a “control” study using what might be a comparably stressful experience here on Earth: climbing Mount Everest. Catherine also shares a recent study that confirmed what one reddit user posted 5 years ago: A single path stretching from southern Pakistan to northeastern Russia will take you on the longest straight-line journey on Earth, via the ocean. Finally, Sarah talks with Roland Kröger of the University of York in the United Kingdom about his group’s study published this week in Science. Using a combination of techniques usually reserved for materials science, the group explored the nanoscale arrangement of mineral in bone, looking for an explanation of the tissue’s contradictory combination of toughness and hardness. This week’s episode was edited by Podigy. Listen to previous podcasts.
