Trillions of microorganisms live on and in the human body, many of them essential to its function and health. These organisms, collectively known as the microbiota, outnumber cells in the body by at least five times.
Microorganisms in the intestinal tract, the gut microbiota, play an especially important role in human health. An investigation on the International Space Station, Rodent Research-7 (RR-7), studies how the gut microbiota changes in response to spaceflight, and how that change in turn affects the immune system, metabolic system, and circadian or daily rhythms.
Research shows that the microbiota in the mammalian digestive tract has a major impact on an individual’s physiology and behavior. In humans, disruption of microbial communities has been linked to multiple health problems affecting intestinal, immune, mental and metabolic systems.
The investigation compares two different genetic strains of mice and two different durations of spaceflight. Twenty mice, ten of each strain, launch to the space station, and another 20 remain on the ground in identical conditions (except, of course, for the absence of gravity). Mice are a model organism that often serves as a scientific stand-in for other mammals and humans.
Fecal material collected from the mice every two weeks will be examined for changes in the gut microbiota. Researchers plan to analyze fecal and tissue samples after 30 and 90 days of flight to compare the effects of different durations of time in space.
With a better understanding of relationships between changes such as disruption in sleep and an imbalance of microbial populations, researchers can identify specific factors that contribute to changes in the microbiota. Further studies then can determine proactive measures and countermeasures to protect astronaut health during long-term missions.

Not all books can be comforting, not all books are make-believe, not all books are heart-racing suspenseful; Gavin De Becker’s The Gift of Fear is all three. Gavin De Becker, the author, shares with us the stories of his clients who were raped by strangers, celebrities stalked by ‘regular people’, obsessed coworkers and more. He dissects them to show them, and us, where and when we should trust our gut and how it really isn’t our gut, but our logical mind setting off warning flags that society has told us to ignore.
I’m reminded of an SVU episode wherein thinking she’s just being racist, a young white girl allows a big black guy into her apartment to help her unload her groceries—she didn’t need the help, and she wasn’t being racist, there was something about him that she knew was off but told herself she should ignore it and then got raped. There are people who are racist, this book nor I ignore that, but just as women have been taught to smile, we have all been taught to be kind and understanding—even when we shouldn’t be. Sometimes it doesn’t matter much, but sometimes it means the end of our lives. He reminds us, me, of the phrase “look at someone’s actions, not at someone’s words”—he reminds us that people choose to be nice, charming—it doesn’t mean they are. He gives a list and more descriptions about Pre-Incident Indicators: methods used by those trying to get something from you that they are used to people ignoring:
Trying to make you two a team
Making you feel sympathy
Locking you down and trying to force a connection
Making a situation where you feel it’d be rude to not speak to THIS COMPLETE STRANGER
Trying to get you into your debt
Trying to make a deal with you, when really they could just leave
Refusing to hear the word no
People say this book could save your life, no. It reminds you that you already have the power to save and fight for your life, you just have to recondition yourself to listen to yourself and trust what someone is showing you. The aspects of this book being real and harrowing are obvious, the issues of comforting is how it allows us to trust ourselves again. This book isn’t just for young women, mothers, or the elderly. I’ve shared this book with managers, coworkers, friends and more. Share this book, read it’s tales and learn how you can survive. It’s awful, but as we know have work-place shootings as part of our fire safety, and the access the internet provides others with our personal details, this book is only becoming more important
