Studying the Genetics of Organisms in Space

At NASA's Kennedy Space Center, organisms in a Petri plate are exposed to blue excitation lighting in a Spectrum prototype unit. NASA scientists and engineers are developing experiments to determine how different organisms, such as plants, microbes or worms, develop under conditions of microgravity. via NASA http://ift.tt/2ySUIzn
