DARPA’s SIGMA program—whose goal is to prevent attacks involving radiological “dirty bombs” and other nuclear threats—concluded its biggest and longest test deployment of vehicle-mounted radiation detectors in Washington, D.C., in February. For approximately seven months starting in July 2016, the fleet of D.C. Fire and Emergency Medical Services ambulances was outfitted with DARPA-developed nuclear and radiological detectors, providing the first city-scale, dynamic, real-time map of background radiation levels throughout the Capital as well as identifying any unusual spikes that could indicate a threat.

A DARPA program that is developing a field-deployable system for onsite neutralization of bulk stores of chemical warfare agents (CWA) has successfully demonstrated a novel waterless soil-scrubbing technology that safely neutralized toxic chemicals simulating sarin, soman, and mustard agents. Created under the Agency’s Agnostic Compact Demilitarization of Chemical Agents (ACDC) program, the technology demonstrated greater than 99.9999% removal of the simulants, without creating any hazardous waste by-products.
Picture an intelligence officer in the field. She is trying to piece together a suspected threat, and has access to someone who may have a role in carrying it out. There may be traces of biological or chemical agents on his clothing or hair. She can look for them, but they’re transient, and often present in such low concentrations that she’ll need to send samples to a laboratory. Or she can check his epigenetic markers, read a history of any time he’s been exposed to threat agents, and start piecing together a chain of evidence right there in the field, in real time.
Bacteria underpins much of our world, acting behind the scenes to affect the health and behavior of animals and plants. They help produce food, provide oxygen, and even reshape the environment through a vast array of biological processes. They come in a phenomenal number of strains—many still unknown—and thrive in different ecological and environmental niches all over the world. But while their diverse behaviors makes them essential to life, bacteria can also be deadly.
Advanced commercially available technologies—such as additive manufacturing (3-D printing), small-scale chemical reactors for pharmaceuticals, and CRISPR gene-manipulation tools—have opened wide access to scientific exploration and discovery. In the hands of terrorists and rogue nation states, however, these capabilities could be misused to concoct chemical, biological, radiological, nuclear, and high-yield explosive (CBRNE) weapons of mass destruction (WMD) in small quantities and in form factors that are hard to detect.
