• Teams show robust radio techniques at Spectrum Challenge event

    Radios are used for a wide range of tasks, from the most mundane to the most critical of communications, from garage door openers to first responders to military operations. Wireless devices often inadvertently interfere with and disrupt radio communications, and in battlefield environments adversaries may intentionally jam friendly communications. To stimulate the development of radio techniques that can overcome these impediments, the agency launched its Spectrum Challenge — a competitive demonstration of robust radio technologies that seek to communicate reliably in congested and contested electromagnetic environments without direct coordination or spectrum preplanning.

  • Microbial power storage can do the job

    Oil and gas can be converted into electricity in line with demand, but wind, water, and sun cannot be adapted as readily to fluctuations in power consumption. Efficient power storage solutions must satisfy two essential criteria: Their own consumption of resources must be as low as possible, and surplus power must be stored within seconds. The results of a pilot study have now demonstrated that a microorganism-based process developed by is unequalled in the way it satisfies both of these criteria.

  • Smartphone “microscope” can detect a single virus, nanoparticles

    Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair. Researchers have created a portable smartphone attachment that can be used to perform sophisticated field testing to detect viruses and bacteria without the need for bulky and expensive microscopes and lab equipment. The device weighs less than half a pound.

  • Extracting maximum energy from currents

    In the long sprint to find new sources of clean, low-cost power, slow and steady may win the race — the slow-moving water of currents and tides, that is. Just as wind turbines tap into the energy of flowing air to generate electricity, hydrokinetic devices produce power from moving masses of water.

  • World's first grid-scale isothermal compressed air energy storage system

    A New Hampshire company has completed construction and begun startup of the world’s first megawatt-scale isothermal compressed air energy storage (ICAES) system. The system stores and returns megawatts of electricity to provide long-term grid stability and support integration of renewable energy sources like wind and solar. Unlike chemical battery systems, ICAES performance does not degrade over its lifetime or need frequent replacement. No hazardous materials are used.

  • History of explosives highlighted in museum exhibit

    For more than seventy years, Los Alamos National Laboratory has been a frontrunner in explosives research, development, and applications. To highlight the Laboratory’s work in the field of explosives, the Bradbury Science Museum is opening a new exhibit, titled “The Science of Explosives.”

  • Unified military intelligence picture dispels the fog of war

    Military operations depend upon the unimpeded flow of accurate and relevant information to support timely decisions related to battle planning and execution. To address these needs, numerous intelligence systems and technologies have been developed over the past twenty years, but each of these typically provides only a partial picture of the battlefield, and integrating the information has proven to be burdensome and inefficient. DARPA’s Insight program aims to bring real-time, integrated, multi-source intelligence to the battlefield.

  • Bomb-detecting lasers to improve security checkpoints

    Research has put the possibility of bomb-detecting lasers at security checkpoints within reach by developing a laser that can detect micro traces of explosive chemicals on clothing and luggage. The laser not only detects the explosive material, but it also provides an image of the chemical’s exact location, even if it’s merely a minute trace on a zipper.

  • Flexible vehicle-arrest system stops cars involved in crime, terrorism

    Researchers have developed a mathematical model that could help engineers design a flexible vehicle-arrest system for stopping cars involved in criminal activity or terrorism, such as suspect car bombers attempting break through a check point, without wrecking the car or killing the occupants.

  • New detectors for chemical, biological threats

    In the late 1990s, Sandia scientists developed a simple-to-use handheld chemical detector for the military, the MicroChemLab. Ever since, Sandia has improved such microfluidics- and microelectromechanical (MEMS) systems-based instruments that identify chemicals based on gas chromatography, or GC, and resonator-style instruments such as surface acoustic wave (SAW) detectors. The lab’s researchers are building on this sensor work to invent tiny detectors that can sniff out everything from explosives and biotoxins to smuggled humans.

  • Top Five most awesome robots

    In the last decade, robots have often been employed on the battlefields of Iraq and Afghanistan, usually to seek out hidden bombs. More and more of these the robots are now being adopted by first response agencies to help in search-and-rescue operations in the wake of disasters. The growing interest in – and usefulness of — robotics have also inspired a series of competitions and challenges, some of which are directed at high-school and college students, to encourage budding scientists to go into the field of robotics.

  • 3D Earth model accurately pinpoints source of earthquakes, explosions

    During the cold war, U.S. and international monitoring agencies could spot nuclear tests and focused on measuring their sizes. Today, they are looking around the globe to pinpoint much smaller explosives tests. Researchers are working on developing a 3-D model of the Earth’s mantle and crust called SALSA3D. The purpose of this model is to assist the U.S. Air Force and the international Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) in Vienna, Austria, more accurately locate all types of explosions.

  • New technology improves IED detection

    Improvised explosive devices, or IEDs, are homemade bombs that can both injure and kill civilians and service members. One solution to the problem of IEDs is to find them before they explode by detecting the chemicals used in the explosives. Scientists at the U.S. Naval Research Laboratory (NRL) have developed a technology, using silicon to fabricate a sensor that may revolutionize the way trace chemical detection is conducted

  • Unmanned undersea platform network to help better deploy naval capabilities

    Today’s naval forces rely primarily on highly capable multifunctional manned platforms, such as ships and submarines. Even the most advanced vessel, however, can only be in one place at a time, making the ability to respond increasingly dependent on being ready at the right place at the right time. New Hydra program aims to make it easier, faster, and cheaper to deploy crucial capabilities worldwide.

  • World's smallest drone may be a search-and-rescue tool

    See video

    Researchers have designed, built, and tested the world’s smallest open source autopilot for small unmanned aircraft. A smaller and lighter autopilot — it weighs only 1.9 grams — allows these small flying robots to fly longer, fit into narrower spaces, or carry more payloads such as cameras. This makes them more suitable to be used, for example, rescue operations.
