Scientists Develop Kill Switches In Case Bioengineered Microbes Go Rogue

schwit1 quotes UPI:
Scientists at Harvard have developed a pair of new kill switches that can be used to thwart bioengineered microbes that go rogue. Researchers have been testing the use of bioengineered microbes for a variety of purposes, from the diagnosis of disease in the human body to the neutering of mosquitoes. But there remain concerns about releasing manipulated microbes into nature. Could their augmented genes have unintended consequences? Could they morph and proliferate? Kill-switches ensure the microbes effectively shutdown, or commit suicide, after they’ve executed their intended function. While kill switches have proven effective in the lab, researchers suggest kill-switch technologies needed to be improved to ensure safety in real-world environs… The researchers detailed their new kill switches in a new paper published this week in the journal Molecular Cell. “This study shows how our teams are leveraging synthetic biology not only to reprogram microbes to create living cellular devices that can carry out useful functions for medicine and environmental remediation, but to do this in a way that is safe for all,” said Donald Ingber, founding director of the Wyss Institute.
