Summary from elsewhere
The International Space Station (|SS) has low microbial diversity, which could lead to astronaut health issues, according to a study published in Cell.
Researchers found that the microbial communities resemble those found in sanitized environments like hospitals rather than natural settings.
Co-senior study author Pieter Dorrestein explains that increasing microbial exposure could improve astronaut health during long-term space travel.
The study suggests incorporating natural elements, like soil, into the ISS to enhance microbial diversity and astronaut well-being.
The study in question:
My understanding of the lore is that Martians got so good at fighting pathogens, they eradicated all of them, which lead to their immune systems gradually weakening over generations.
Oh yeah! I think I remember that now. So that explains why we can’t catch stuff from them cos they haven’t got anything to pass on.
