2017/12/06 Ocean of Things Aims to Expand Maritime Awareness across Open Seas

Ocean of Things
The internet of things connects an ever-growing number of smart devices for up-to-the-minute monitoring and tracking of many common events. Head out to most parts of the open ocean, however, and no such capability exists for real-time monitoring of maritime activity.

2017/11/21 DARPA Digging for Ideas to Revolutionize Subterranean Mapping and Navigation

Subterranean Mapping and Navigation RFI
Subterranean warfare-whether involving human-made tunnels, underground urban infrastructure, or natural cave networks-has been an element of U.S. military operations from World War II and Vietnam to Iraq and Afghanistan. As above-ground commercial and military intelligence, surveillance, and reconnaissance (ISR) capabilities continue to grow more capable and ubiquitous, adversaries are increasingly heading underground to circumvent detection.

2017/11/17 Nature’s Silent Sentinels Could Help Detect Security Threats

Caption: The Advanced Plant Technologies program aims to engineer a discreet, self-sustaining, plant-based sensor platform able to detect and report on defense-relevant stimuli in natural environments. Researchers on the program will design, build, and test modifications that achieve the desired functionality without decreasing the plants’ environmental fitness.

Few military requirements are as enduring as the need for timely, accurate information.

To meet this demand, the Department of Defense invests heavily in the development of powerful electronic and mechanical sensors, and in the manpower to maintain and operate those sensors. DARPA has been involved on the research side of the equation since the Agency's earliest days, developing technologies such as the VELA satellites and seismographs to ensure Soviet compliance with the Nuclear Test Ban Treaty.

2017/11/15 Developing “ABCs” for Exploiting New Phenomena in Light-Matter Interactions
15/11/2017 06:00:00 Darpa
Image Caption: DARPA's Nascent Light-Matter Interactions (NLM) program aims to develop theory-anchored models that could yield new structures for materials with never-before-seen electromagnetic properties. This artist's concept depicts an example of how an engineered material might be able to convert, generate, or harvest electromagnetic fields exploiting interactions that could have far-reaching effects in areas such as sensing, thermal control, frequency conversion, and dynamics.
A unique class of engineered light-manipulating materials, known as metamaterials or structured materials, makes use of patterns of strongly interacting wavelength or sub-wavelength-sized elements. Because of these intricate internal and surface structures, new properties have emerged, some exhibiting behavior that has resulted in rewriting long-understood "laws" for how light and other electromagnetic (EM) waves interact with materials. These materials have been opening up new options for controlling EM waves in many technological arenas, among them imaging, thermal control, and frequency conversion. Specific applications include night-vision, heat reflection and management in aircraft engines, and temperature regulation of electronics on satellites in the hot-and-cold extremes of space.

2017/11/08 Steven H. Walker Appointed 21st DARPA Director

Dr. Steven Walker
The Under Secretary of Defense for Acquisition, Technology, and Logistics, Ms. Ellen M. Lord, today announced the appointment of Dr. Steven H. Walker as the 21st director of the Defense Advanced Research Projects Agency (DARPA). A former DARPA program manager, deputy office director, and office director, Walker has devoted 13 of his more than 30 years of public service to the Agency and been a key figure in advancing the science and technologies associated with hypersonic flight and rapid access to space.
