Long-term space missions pose serious health risks. A new study from McGill University uncovers how space travel alters gut bacteria and metabolism. The research, published in npj Biofilms and Microbiomes, highlights concerning changes in the gut microbiome of mice on the International Space Station (ISS). These changes were observed over three months.
Researchers used advanced genetic tools to analyze gut bacteria, liver function, and intestinal genes. The study, backed by NASA and global space agencies, found critical shifts in the gut-liver axis. This pathway regulates metabolism and immune function, making these changes a major concern for astronaut health related to space travel.
DISRUPTIONS IN GUT-LIVER CONNECTION
Scientists observed notable alterations in gut bacteria linked to liver and intestinal gene activity. These disruptions may weaken the immune system and trigger metabolic imbalances. Risks include glucose and lipid dysregulation, which could affect astronauts’ health on long-duration space travel missions.
EXPERT INSIGHTS ON SPACEFLIGHT CHANGES
“Spaceflight extensively alters astronauts’ bodies, yet we still don’t fully understand why,” said lead researcher Emmanuel Gonzalez. He emphasized that combining genetic and microbiome analysis helps identify patterns and potential solutions related to space travel.
PREPARING FOR FUTURE MISSIONS
These findings go beyond current spaceflights. They offer crucial insights for future Moon and Mars missions. Understanding how space travel affects the human body is essential for ensuring astronaut safety in deep space exploration.
ADVANCING SPACE HEALTH RESEARCH
Scientists continue to explore the complexities of space travel’s effects on human physiology. This study marks a vital step toward protecting astronauts and paving the way for longer missions beyond Earth.
