Algae grew for 40 generations on the ISS; spaceflight produced 50% more DNA changes than Earth

Researchers have successfully cultivated microalgae aboard the International Space Station to study their genetic stability. The Space Algae-1 experiment recorded a 50% increase in DNA polymorphisms compared to ground controls. Nasa is examining the implications of these changes for potential long-duration space missions. Following this, the Space Algae-2 experiment will investigate an edible cyanobacterium known as Spirulina. This research focuses on understanding the evolutionary responses of
