• New technology to boost food security

    A scientist in the Philippines develops a new method for keeping food fresh; brine-immersion freezing, or BIF, allows fish and meat can be stored for two to three days in styrofoam boxes without using ice, and up to six months when stored in freezers or chillers

  • Day of quantum communications in the theater nears

    The challenges so far with free space optical links, which use fibre optics for transmission, have been the turbulence or distortions from temperature differences that cause motion or wind in the atmosphere; researchers have established an optical link without distortion in test situations at a distance of 35km in stationary and flight situations

  • New high-precision chemical detector to be commercialized

    A start-up launched by the University of Delaware is preparing to commercialize a high-precision detector — a planar-array infrared spectrograph — that can identify biological and chemical agents in solids, liquids, and gases present at low levels in less than a second

  • DARPA announces a $40,000 red-balloon Network Challenge

    To celebrate the Internet’s 40th anniversary, DARPA will moor ten 8-foot red weather balloons across the continental United States during the daylight hours of 5 December; the first individual — or group — to identify the location of the balloon will receive $40,000

  • Questions raised about Obama's smart grid funding

    For the smart grid project to succeed, the business case for it needs to be widely accepted by the stakeholders involved (skeptics would say that if efficiency-mindedness was at the top of the agenda in utility boardrooms and state regulatory agencies, then no federal stimulus money would be needed to install these kinds of technologies); also: the Obama plan envisions a joint public-private smart grid expenditure of $8.1 billion — the government’s $3.4 billion is being matched by $4.7 billion in private investment; a recent analysis of what it would take to build a unified national smart grid put the tab for such a grid at $400 billion

  • The brief

    Smart grid technologies may themselves introduce new problems, such as increasing the vulnerability to cyber attack, as power grid resources become increasingly linked to the Internet

  • Robotic platform helps soldiers carry heavy gear

    Israel Aerospace Industries unveils robotic platform designed for ground forces; the platform, carrying up to 200kg of gear, follows the lead soldier from a distance; the soldiers control the platform by using simple commands, including “stop,” “fetch,” and “heel”

  • New material makes buildings more fire resistant

    New material, called “liquid granite,” is fire resistant to temperatures in excess of 1,100oC; it reduces the fire risk in buildings because, unlike concrete, it does not explode at high temperatures

  • New device to "smell" human fear

    City University London’s researchers launch a project aims to develop two sensor systems that can detect the unique chemical signature of the fear pheromone, assessing the stress of an individual and interpreting it in security-critical contexts

  • Humanoid robots to help people in hazardous environments

    Current calculations required for robots’ handling objects and avoiding collisions are based on movements in the XYZ coordinates, and are sensitive to any minor deformations in the environment, such as a flexible object that would cause the calculations to be invalid; researchers offer a new way to govern robots’ movement

  • Fingerprint technology beats world’s toughest tests

    Among the fingerprints most difficult to identify are those of brick-layers, but a new technique developed by University of Warwick researchers did so successfully; the secret: the University of Warwick researchers consider the entire detailed pattern of each print and transform the topological pattern into a standard co-ordinate system

  • Israeli company shows unmanned smart-missile pack

    A large box contains several vertically launched missiles and its own communications and power; it is generally light enough to be driven about by a Humvee or similar, parachuted down from a transport plane, dropped off by helicopter, tied down on the deck of a ship or barge; the missiles are launched by remote control

  • A new Amsterdam neighborhood floats on a lake

    The Dutch experiment with a new concept for addressing over-crowding, flooding, and rising sea-level problems: floating neighborhoods

  • New method takes 0.2 second to test for explosive liquids

    German scientists develop a novel nanoelectronic device which uses electromagnetic radiation to identify explosive liquids, or liquid components for the fabrication of explosives, in usual plastic bottles almost instantly

  • Mitchell Zakin revived the chemistry discipline at DARPA

    Mitch Zakin —who says, “I joined DARPA because it is unfettered by conventional wisdom” — will leave the agency in 2010; he has been working on developing “the infochemistry project,” which combines the powers of chemistry and information technology
