Neutron Vision: Going Beyond X-Rays for Advanced Imaging in the Field

DARPA’s Intense and Compact Neutron Sources (ICONS) program seeks to develop a portable unit able to generate both neutrons and X-rays. Such a device would harness the complementary strengths of the two imaging sources and enable much more detailed radiography in field settings
Seeking to expand the nation’s capability to detect and identify materials that are not easily visualized by conventional imaging technologies, DARPA today released an announcement inviting proposals to develop portable, next-generation imaging tools that combine the complementary benefits of X-ray and neutron radiography.    Article

Seeing Through the Fog (and Dust and Snow) of War

MFRF 

Degraded visibility—which encompasses diverse environmental conditions including severe weather, dust kicked up during takeoff and landing and poor visual contrast among different parts of terrain—often puts both the safety and effectiveness of tactical helicopter operations at risk. Current sensor systems that can provide the necessary visualization through obscurants struggle with latency and are too large, heavy and power-intensive to comply with military rotary wing operations.

Lightweight, Soft Exosuit Aims to Prevent Musculoskeletal Injury in Warfighters

Warrior Web 

Harvard University’s Wyss Institute for Biologically Inspired Engineering is continuing development of a lightweight, soft exosuit for DARPA’s Warrior Web program, which is aimed at creating technologies that mitigate musculoskeletal injuries among warfighters while improving performance. The Wyss team is seeking to integrate component technologies developed in separate Warrior Web efforts into a prototype suit that offers expanded capabilities. DARPA plans to test the final suit in appropriate mission profiles under realistic loads to evaluate performance. Article

Blood-cleansing “Artificial Spleen” Technology Could Increase Survival Odds for Future Sepsis Patients

Shield 

Sepsis—a life-threatening over-reaction by the immune system to infection—afflicts 18 million people a year worldwide and kills between 30 and 50 percent of them. Sepsis poses a significant threat to warfighters who suffer combat injuries that predispose them to infection. Antibiotics can kill sepsis-inducing microbes but their overuse is contributing to the threat of drug-resistant microbes and they don’t neutralize the toxins that some pathogens leave behind. Commercial dialysis equipment can remove toxins from the blood but is not built for routine use in theater. Article

SIMPLEX seeks to use mathematical models and tools to represent complex, diverse scientific data in a computable format to speed discovery, analysis and hypothesis generation. This diagram depicts the iterative discovery process that SIMPLEX aims to facilitate.

New Mathematical Tools Seen as Key to Maximizing Value of Scientific Data and Accelerating Discovery

SIMPLEX seeks to use mathematical models and tools to represent complex, diverse scientific data in a computable format to speed discovery, analysis and hypothesis generation. This diagram depicts the iterative discovery process that SIMPLEX aims to facilitate. 

The exponential growth of diverse science data represents an unprecedented opportunity to make substantial advances in complex science and engineering, such as discovery of novel materials or drugs. However, without tools to unify principles, results, models and other kinds of data into a single computational representation, it is difficult to relate data from any one scientific problem or area to the broader body of knowledge.

DARPA’s Electronic-Photonic Heterogeneous Integration (E-PHI) program has successfully integrated billions of light-emitting dots on silicon to create an efficient silicon-based laser. The breakthrough, achieved by researchers working on the program at the University of California, Santa Barbara (UCSB), will enable the production of inexpensive and robust microsystems that exceed the performance capabilities of current technologies.  Article
