A new report appearing in The Journal of Leukocyte Biology (http://www.jleukbio.org) argues that human missions to Mars, as well as all other long-term space flights might be compromised by microbial hitchhikers, such as bacteria. That's because long-term space travel packs a one-two punch to astronauts: first it appears to weaken their immune systems; and second, it increases the virulence and growth of microbes. This combination of factors makes it vital for scientists to find tools that can help people cope with these microscopic hitchhikers before they lead to disease, especially since astronauts will not have the ability to return home to a hospital...
