- 1Blood tests explain why astronauts get constipated in space▼Blood tests reveal why astronauts get constipated in space
Researchers say blood tests have identified why astronauts often suffer constipation during spaceflight, pointing to changes in the body measurable in the blood while in orbit. The finding sheds light on a common but rarely discussed problem of long-duration missions and could help protect crew health on future trips to the Moon and Mars.

An article in The Conversation examines how astronauts' sleep is disrupted in orbit, where the absence of a normal day-night cycle throws off circadian rhythms. It explores what space travel reveals about the biology of sleep and how those lessons could improve sleep health for people on Earth.
- 3The Ideal Candidates for Interstellar Travel●The Ideal Candidates for Interstellar Travel https:// buymeacoffee.com/newscafe/the- first-biological-astronauts-sent-be
A discussion is under way about which biological organisms would make the best candidates for humanity's first missions beyond the solar system, arguing that humans themselves are unlikely to be the first biological astronauts sent that far. The piece points to research on hardy life forms suited to long-duration interstellar conditions, prompting debate about what future deep-space exploration might actually look like.

A doctoral student at the University of Mississippi is researching how microbes could be used to support future lunar habitats. The work explores ways microorganisms might help sustain life on the Moon, such as aiding resource production or environmental control for astronauts. The university has highlighted the project, drawing attention to the growing role of biology in space exploration and the student's contribution to this emerging field.
- 7Microgravity Simulation Reveals Unexpected Changes in Human Cell DNA●Scientists Simulated Microgravity in Human Cells and Found Something Unexpected About DNA
Scientists simulated microgravity conditions in human cells in the laboratory and discovered unexpected effects on DNA. The findings add to growing evidence that altered gravity can influence how genetic material behaves, with implications for astronaut health and long-duration space missions. Details of the study and the exact nature of the DNA changes were not specified in available coverage.
