riboswitches

Today in my searches for the hot new trends in synthetic biology, I found a news article from Science Daily with an intriguing title: "Scientists Achieve First Rewire of Genetic Switches." Rewiring genetic switches sounds pretty neat, but this headline was intriguing to me first of all because it's kind of late to the party--in fact one of the first papers in modern synthetic biology back in 2000 was about engineered genetic switches: "Construction of a genetic toggle switch in Escherichia coli". When I looked more closely, the article wasn't about this kind of transcriptional switch though,…
