DARPA’s SIGMA program, which began in 2014, has demonstrated a city-scale capability for detecting radiological and nuclear threats that is now being operationally deployed. DARPA is building off this work with the SIGMA+ initiative that is focused on providing city- to region-scale detection capabilities across the full chemical, biological, radiological, nuclear, and explosive threat space.
X-rays and gamma rays have a wide range of applications including scanning suspicious maritime shipping containers for illicit materials, industrial inspection of materials and processes, and medical diagnostic and therapeutic procedures. Current technologies, however, are not ideal. X-rays produce a continuum of energies that limit their inspection and diagnostic performance, and gamma rays can only be produced at specific energies unique to a given radioactive isotope.
Breakthroughs in the science of programmable gene expression inspired DARPA to establish the PReemptive Expression of Protective Alleles and Response Elements (PREPARE) program with the goal of delivering powerful new defenses against public health and national security threats. DARPA has now selected five teams to develop a range of new medical interventions that temporarily and reversibly modulate the expression of protective genes to guard against acute threats from influenza and ionizing radiation, which could be encountered naturally, occupationally, or through a national security event.
As some 300,000 cheering race fans packed the stands at this year’s Indianapolis 500, behind the scenes an advanced network of sensors kept constant vigilance, providing security officials real-time awareness of any potential weapon-of-mass-destruction/terror (WMD/WMT) threat. The deployment marked the first time that DARPA’s SIGMA+ network seamlessly integrated radiological and chemical sensors with biological threat sensors from the Department of Homeland Security’s Countering Weapons of Mass Destruction (CWMD) Office.
In this episode of the Voices from DARPA podcast, Mark Wrobel, a program manager since 2019 in the agency’s Defense Sciences Office (DSO), chronicles progress in the SIGMA+ program and its potential near-term relevance to monitoring the environment for SARS-CoV-2, the virus that causes COVID-19.
