“Infectious pathogens like Salmonella typhimurium employ a startling array of techniques to skillfully outwit the body’s defense mechanisms and produce illness. Through their expression of genes—the fundamental building blocks of cellular physiology—such microbes ingeniously adapt to varied environments, modifying their disease-causing potential or virulence.

Although the study of a broad range of microbial virulence factors is now well advanced, many pieces of the puzzle are still missing…spaceflight experiments have shown that Salmonella gene expression and virulence are profoundly altered by microgravity, with the pathogenic cells undergoing a significant increase in their infectious disease potential….” Full Slice

Just think about what might be found if we choose to actually look more often.

[Note that many are those that claim there are NO valuable rewards from our so called fixation on space flight]
