Moonshot: Spy corn
With synthetic biology, a new way to tell when danger is in the air
In the same spirit that drove the engineers of the Apollo 11 mission to accomplish what had seemed impossible, Raytheon's innovators are working on world-changing technologies that push the limits of what people can do. Here, as part of the series we call "The Next Moonshots," we explore how synthetic biology can turn ordinary things into extraordinary intelligence-gathering tools.
WHAT IT WILL BE
Specially engineered crops and other living things that react to something in the environment – such as harmful chemical or biological agents – then change their appearance slightly as a secret signal to those who need to know.
WHY WE NEED IT
Analyzing the air in a combat zone without actually being there would protect troops, and doing it unbeknownst to the enemy would be an intelligence win. It's just one potential use of synthetic biology – an emerging and ethically complex field that, when done responsibly, could bring major improvements in areas such as military technology, healthcare, agriculture and energy.
WHY IT'S A MOONSHOT
There's no way around it: Synthetic biology means you're altering nature. It requires attributing everything about an organism back to something in its cellular structure, then treating those cells like computer chips, inserting circuits and essentially reprogramming until you get the desired effect.
It's hard enough to do that once, but to get synthetic biology to work, you have to do it repeatedly, said Susan Katz, a computer scientist at Raytheon BBN technologies. You have to do it at scale.
"Cells are so smart," she said. "You have to work really hard to get them to do what you want them to do, and get them to do it over and over again."
WHAT IT TAKES
Modeling, testing and engineering discipline. Synthetic biology starts with using computer-aided design tools to draw circuits and simulate their response to certain situations, then analyzing the data and making adjustments along the way. It's a little less exciting than putting things in test tubes – but no less important.
"Bringing that kind of discipline, of building systems and testing systems, into this area, gives us a lot of experience that is very useful," Katz said.
HOW IT WILL CHANGE THE WORLD
At its best, synthetic biology could create highly precise medications, crops that need less water, materials that require no petroleum and meat that requires no animals (and produces no harmful emissions).
"The sky is the limit for the advances that can be made in the health and welfare of the world's population," Katz said. "The world can be a better place with this technology."
