John Arnst walked away from the lab bench, then returned to it to process far-flung influenza samples and wound up promoting a flu vaccine campaign for K–12 schools in North Central Florida. At one point, he smashed more than 200 tomatoes in two hours for a project involving Salmonella and then couldn’t bear to eat any for more than a year. He graduated from the University of Florida in 2013 with degrees in English and biology. He was a science writer for 91亚色传媒 Today for about four years. He is now a freelance science writer.
