How do you set exposure limits to protect human health in a closed container floating in space? Valerie Ryder, a toxicologist at the NASA Johnson Space Center, takes co-hosts Anne Chappelle and David Faulkner into the small world of space toxicologists, where they also discuss research involving lunar dust, bone loss, and CO2.

The Piketon Massacre

The most notorious mass murder in Ohio’s history happened on the night of April 21, 2016 in rural Pike County. Four crime scenes, thirty-two gunshot wounds, eight members of the Rhoden family left dead in their homes. Two years later a local family of four, the Wagners, are arrested and charged with the crimes. As the Wagners await four back-to-back capital murder trials, the KT Studios team revisits Pike County to examine: crime-scene forensics, upcoming legal proceedings, and the ties that bind the victims and the accused. As events unfold and new crimes are uncovered, what will it mean for all involved? What will it mean for Pike County?
