  • 2017/03/23 Turning to Chemistry for New “Computing” Concepts
    As the complexity and volume of global digital data grows, so too does the need for more capable and compact means of processing and storing data. To address this challenge, DARPA has announced its Molecular Informatics program, which seeks a new paradigm for data storage, retrieval, and processing. Instead of relying on the binary digital logic of computers based on the Von Neumann architecture, Molecular Informatics aims to investigate and exploit the wide range of structural characteristics and properties of molecules to encode and manipulate data.
  • 2017/03/17 Taking Animal Magnetism to the Extreme
    Each beat of your heart or burst of brain activity relies on tiny electrophysiological currents that generate minuscule ripples in the surrounding magnetic field. These field variations provide the basis for a range of research tools and diagnostic techniques with mouthful names like magnetoencephalography (MEG) and magnetocardiography (MCG). But tapping into biology's faint magnetic fields requires heroic and costly measures, including high-tech shields to block the larger, potentially confounding magnetic forces all around us and boutique magnetic field sensors that require expensive and cumbersome liquid helium cooling.
  • 2017/03/16 Bushwhacking into Unexplored Transistor Territories
    Since the advent of microelectronics in the mid-20th century, humanity has been on a nonstop sprint to eke more speed, power efficiency, and computational power from the sextillions (1021) of ever more miniaturized transistors that have come to underlie so much of the modern technoscape.
  • 2017/03/16 Toward Machines that Improve with Experience
    Self-driving taxis. Cell phones that react appropriately to spoken requests. Computers that outcompete world-class chess and Go players. Artificial Intelligence (AI) is becoming part and parcel of the technological landscape-not only in the civilian and commercial worlds but also within the Defense Department, where AI is finding application in such arenas as cybersecurity and dynamic logistics planning.
  • 2017/03/15 The Uncertainty Wrangler
    In the latest episode of DARPA podcast series, Voices from DARPA, Fariba Fahroo of the Agency's Defense Sciences Office discusses just how pivotal mathematics can be for, in her words, "keeping our models honest." By characterizing the uncertainties inherent in the computer models we use to better understand complex phenomena, such as the flow of air over aircraft surfaces and through high-performance engines, as well as to design, engineer, and control today's ever more complicated civilian and military systems, Fahroo aims to develop modeling frameworks by which these systems can be built and deployed with more confidence and insight than ever into their strengths and vulnerabilities.
  • 2017/03/15 Progress Toward an Ability to Recover Unmanned Aerial Vehicles on the Fly
    DARPA recently completed Phase 1 of its Gremlins program, which envisions volleys of low-cost, reusable unmanned aerial systems (UASs)-or "gremlins"-that could be launched and later retrieved in mid-air. Taking the program to its next stage, the Agency has now awarded Phase 2 contracts to two teams, one led by Dynetics, Inc. (Huntsville, Ala.) and the other by General Atomics Aeronautical Systems, Inc. (San Diego, Calif.).
  • 2017/03/01 Radioactive Threat Detection System Completes Emergency Vehicle Test Deployment in Nation’s Capital
    DARPA's SIGMA program-whose goal is to prevent attacks involving radiological "dirty bombs" and other nuclear threats-concluded its biggest and longest test deployment of vehicle-mounted radiation detectors in Washington, D.C., in February. For approximately seven months starting in July 2016, the fleet of D.C. Fire and Emergency Medical Services ambulances was outfitted with DARPA-developed nuclear and radiological detectors, providing the first city-scale, dynamic, real-time map of background radiation levels throughout the Capital as well as identifying any unusual spikes that could indicate a threat.
  • 2017/02/09 DARPA Selects SSL as Commercial Partner for Revolutionary Goal of Servicing Satellites in GEO
    In an important step toward a new era of advanced, cost-effective robotic capabilities in space, DARPA today announced that it has selected Space Systems Loral (SSL), based in Palo Alto, CA, as its commercial partner for the Agency's Robotic Servicing of Geosynchronous Satellites (RSGS) program. DARPA and SSL seek to develop technologies that would enable cooperative inspection and servicing of satellites in geosynchronous orbit (GEO), more than 20,000 miles above the Earth, and demonstrate those technologies on orbit.
  • 2017/02/07 RadioBio: What role does electromagnetic signaling have in biological systems?
    For decades scientists have wondered whether electromagnetic waves might play a role in intra- and inter-cell signaling. Researchers have suggested since the 1960s, for example, that terahertz frequencies emanate from cell membranes, but they've lacked the technology and tools to conduct reproducible experiments that could prove whether electromagnetic waves constitute purposeful signals for biological function-or if they're merely background noise. With recent advances in technology and modeling, experiments may now be possible to test signaling hypotheses.
  • 2017/02/06 SideArm Prototype Catches Full-Size Unmanned Aerial System Flying at Full Speed
    Few scenes capture the U.S. Navy's prowess as effectively as the rapid-fire takeoff and recovery of combat jets from the deck of an aircraft carrier. The ability to carry air power anywhere in the world, and both launch those aircraft to flight speed and bring them to a stop over extremely short distances, has been essential to carriers' decades-long dominance of naval warfare. To help provide similar capabilities-minus the 90,000-ton carriers-to U.S. military units around the world, DARPA's SideArm research effort seeks to create a self-contained, portable apparatus able to horizontally launch and retrieve unmanned aerial systems (UASs) of up to 900 pounds.
