For more than fifty years, researchers have been studying exactly how aspirin affects the human body. Despite thousands of publications on the topic, our understanding is still incomplete.
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.

The Defense Advanced Research Projects Agency (DARPA) Defense Sciences Office (DSO) is sponsoring a Proposers Day webcast to provide information to potential proposers on the objectives of an anticipated Broad Agency Announcement (BAA) for the Gamma Ray Inspection Technology (GRIT) program.
The Gamma Ray Inspection Technology (GRIT) program seeks transformational approaches to achieving high-intensity, tunable, and narrow-bandwidth gamma ray production, but in a compact form factor suitable for transporting the source to where the capability is needed.
The Rapid Threat Assessment (RTA) program aims to provide critical information to speed production of medical countermeasures to protect U.S. forces against novel chemical and biological weapons. Such weapons have historically been mass-produced within a year of discovery. Development of countermeasures, however, currently takes far longer. Using current methods and technologies, researchers require decades of study to gain a cellular-level understanding of how new threat agents exert their effects.
