The structural materials that are currently used to construct homes, buildings, and infrastructure are expensive to produce and transport, wear out due to age and damage, and have limited ability to respond to changes in their immediate surroundings. Living biological materials—bone, skin, bark, and coral, for example—have attributes that provide advantages over the non-living materials people build with, in that they can be grown where needed, self-repair when damaged, and respond to changes in their surroundings.

A new DARPA program could help unlock the potential of advanced gene editing technologies by developing a set of tools to address potential risks of this rapidly advancing field. The Safe Genes program envisions addressing key safety gaps by using those tools to restrict or reverse the propagation of engineered genetic constructs.

It may not be obvious to humans, but the life of a plant is full of peril. Viruses, pests, fungi, herbicides, drought, pollution, salinity, flooding, and frost—the plants that we depend on for food, clean air, and materials are challenged by myriad threats, natural and man-made. By extension, human populations are put at risk when food security is challenged and the agricultural underpinnings of our economies are destabilized, especially when threats emerge rapidly or unexpectedly.

For decades scientists have wondered whether electromagnetic waves might play a role in intra- and inter-cell signaling. Researchers have suggested since the 1960s, for example, that terahertz frequencies emanate from cell membranes, but they’ve lacked the technology and tools to conduct reproducible experiments that could prove whether electromagnetic waves constitute purposeful signals for biological function—or if they’re merely background noise. With recent advances in technology and modeling, experiments may now be possible to test signaling hypotheses.

DARPA created the Safe Genes program to gain a fundamental understanding of how gene editing technologies function; devise means to safely, responsibly, and predictably harness them for beneficial ends; and address potential health and security concerns related to their accidental or intentional misuse.
