In the second episode of Season 2, Alexa Cohn and Jonathan Sogin take us through two new papers detailing a novel operon structure and antibiotic resistance mechanism. For molecular and non-molecular biologists alike, this episode is sure to bring out the science in Food Science. But, it’s not all about science - Alexa tries painting and Jonathan attempts karate; they definitely won’t be quitting their day jobs anytime soon.
