A DARPA program aimed at preventing attacks involving radiological “dirty bombs” and other nuclear threats has successfully developed and demonstrated a network of smartphone-sized mobile devices that can detect the tiniest traces of radioactive materials. Combined with larger detectors along major roadways, bridges, other fixed infrastructure, and in vehicles, the new networked devices promise significantly enhanced awareness of radiation sources and greater advance warning of possible threats.

On a recent sunny fall day in the nation’s capital, several hundred volunteers—each toting a backpack containing smartphone-sized radiation detectors—walked for hours around the National Mall searching for clues in a “whodunit” scavenger hunt to locate a geneticist who’d been mysteriously abducted. The geneticist and his abduction were fictitious. But the challenge this scavenger hunt was designed to address is real: The need to detect even small quantities of radioactive material that terrorists might try to bring into an urban area with the intent of detonating a “dirty bomb,” or worse.

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.

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.
