DARPA-funded engineers at UC San Diego have developed a material that could reduce signal losses in photonic devices. The advance has the potential to boost the efficiency of various light-based technologies including fiber optic communication systems, lasers, and photovoltaics.

DARPA has always been at the forefront of #ArtificialIntelligence, driving the technology forward, so it's no surprise that we have some pretty definitive views as to where it's headed. Amid the hype and bluster about #AI, DARPA's John Launchbury attempts to demystify the technology by explaining what it currently can do, what it currently cannot do, and where it is headed.

The Global Positioning System (GPS) is the predominant means of obtaining positioning, navigation, and timing information for military and civilian systems and applications. However, the radio frequency basis for GPS also means that its signals cannot penetrate seawater, and thus undersea GPS is effectively denied. DARPA's POSYDON program aims to develop an undersea system that provides omnipresent, robust positioning across ocean basins. By ranging to a small number of long-range acoustic sources, an undersea platform would be able to obtain continuous, accurate positioning without surfacing for a GPS fix.

Coming soon to tech-savvy ears near you: "The Geolocator," Episode 7 of our "Voices from DARPA" podcast. Program Manager Lin Haas will share his insights on position, navigation, and timing technologies, and let us know how he's preparing for a world without GPS.

"The Geolocator" comes out tomorrow, Feb. 14, at 2:00 PM EST. You will be able to access it at http://www.darpa.mil/about-us/podcast.

Time is of the essence when an infectious disease epidemic threatens. And yet, current methods and technologies for containing the spread of disease are inadequate; treatments can take many months, years, or even decades to develop, distribute, and administer. DARPA's new Pandemic Prevention Platform (P3) program aims to cut that response time to 60 days or less, developing a platform technology that can tackle ANY infectious viral threat, whether it's one humans have encountered before or not. Learn more, including what steps will be required to bring this idea to fruition, at: http://www.darpa.mil/news-events/2017-02-06a.

In her final "all hands" presentation to Agency staff, Former DARPA Director Arati Prabhakar highlighted 12 research programs that have the potential to fundamentally recast military capabilities, change national security outcomes, and reshape how future societies live and work.

The presentation took place on December 12, 2016, at DARPA.

Our new RadioBio program will explore whether electromagnetic waves are purposefully transmitted and received within or between cells. If so, DARPA will seek to apply those insights not just to biosystems, but also to communication in cluttered electromagnetic environments.

Over the past several years, DARPA-funded researchers have pioneered RNA vaccine technology, a medical countermeasure against infectious diseases that uses coded genetic constructs to stimulate production of viral proteins in the body, which in turn can trigger a protective antibody response. As a follow-on effort, DARPA funded research into genetic constructs that can directly stimulate production of antibodies in the body. DARPA is now launching the Pandemic Prevention Platform (P3) program, aimed at developing that foundational work into an entire system capable of halting the spread of any viral disease outbreak before it can escalate to pandemic status.

If it is successful, the P3 platform would offer a stark contrast to the state of the art for developing and deploying traditional vaccines—a process that does not deliver treatments to patients until months, years, or even decades after a viral threat emerges.

DARPA’s SideArm research effort seeks to create a self-contained, portable apparatus able to horizontally launch and retrieve unmanned aerial systems (UAS) of up to 900 pounds.

In December 2016, Aurora Flight Sciences successfully tested a full-scale technology demonstration system that repeatedly captured a 400-pound Lockheed Martin Fury UAS accelerated to representative flight speeds via an external catapult. The system is capable of recovering aircraft up to 1,100 pounds, exceeding DARPA’s design objectives.

The work is funded by DARPA's TERN program. Learn more and see a video of the SideArm demonstration at: http://www.darpa.mil/news-events/2017-02-06.

From the Cyber Grand Challenge to the real world, ForAllSecure's Mayhem software is now being tested in certain kinds of commercial software to see if the tools can automatically find and fix flaws. (Story by MIT Technology Review)
