Why you keep falling for the same person, and 9 other things worth discussing this week

This week: a German research team built a water contamination test that runs on a smartphone and gives you an answer in under a minute. A Cornell professor has a gardening trick that involves water, a paper towel, and one night. A Bristol startup figured out what to do with festival urine! Arielle and Karissa also talk about the psychology of why you keep falling for the same type, Earth Day turning 56, and the free home reset that's apparently all about the "invisible layer." And for the first time, an Optimist Daily's Emissary shout-out goes out! Therese highlights Emily Oakley and Michael Appel of Three Springs Farm in Oklahoma, two farmers who've spent over two decades working on food, land, and community.
