Article Correctness Is Author's Responsibility: Space travel can make the gut leaky

Bacteria, fungi, and viruses can enter our gut through the food we eat.

Biomedical scientist have now found that simulated microgravity, such as that encountered in spaceflight, disrupts the functioning of the epithelial barrier even after removal from the microgravity environment.
