• Web services could work with sensitive data -- without decrypting the data

    A cryptographic method could allow cloud services to work with sensitive data without ever decrypting it; a novel technique could see future Web services work with sensitive data without ever being able to read it; several implementations of a mathematical proof unveiled last year will allow cryptographers to start making the proposal more practical.

  • Fibertect absorbent can clean Gulf oil spill's crude, holds toxic oil and mustard vapors

    New material — raw cotton-carbon Fibertect — can absorb oil up to fifteen times its weight; the material can clean up crude oil and adsorb toxic polycyclic aromatic hydrocarbon vapors which sicken oil spill clean-up crew members; also, the material has been tested to successfully remediate mustard vapors such as those found from dumped munitions

  • Robot assembles itself, then flies

    Soldiers and first responders often find themselves in situations of surveillance or search and rescue, in which they may have to figure out on the fly what size and shape surveillance or search-and-rescue robot they need; Swiss researchers develop a flying platform made up of autonomous wheeled vehicle that lock together to share the task of controlled and autonomous flight; this self-sufficient wheeled DFA has another advantage: if one of the parts of which it consists breaks, the robot can reconfigure itself or substitute in a different part

  • Autonomous vehicles to map battle environments

    War is always accompanied by the fog of war; to pierce that fog, researchers at Cranfield University are working on developing swarms of autonomous military vehicles capable of sharing and overlapping video images to create high-resolution 3D panoramic scenes of dangerous battlefield areas

  • Next-generation HazMat boots made of leather

    The rubber boots that emergency personnel wear when responding to situations where hazardous materials (HazMat) are present may be functional, but they are not very comfortable; with the availability of new textile materials and surface treatments, researchers are confident they can develop a comfortable — and functional — leather boot for use in both fire-fighting and HazMat operations

  • The consequences of new surveillance technology

    Many wish for better security in public places, and support installation of new video surveillance technologies to achieve this goal; these surveillance technologies, however, have important psychological and legal implications, and four German universities cooperate in studying these implications

  • Plastic lasers shed light on hidden explosives

    Detecting hidden explosives is a difficult task but now researchers in the United Kingdom have developed a new way of detecting them, with a laser sensor capable of detecting molecules of explosives at concentrations of 10 parts per billion (ppb) or less

  • Green decontaminants to breaking down chemical weapons

    New products developed non-toxically to decontaminate nerve gas, mustard gas, radioactive isotopes, and anthrax. The formulas are based on ingredients found in foods, cosmetics, and other consumer products

  • New method manipulates particles for sensors, crime scene testing

    Researchers develop a new tool for medical diagnostics, testing food and water for contamination, and crime-scene forensics; the technique uses a combination of light and electric fields to position droplets and tiny particles, such as bacteria, viruses, and DNA, which are contained inside the drops

  • U.S. military to adopt NFL's instant replay technology

    U.S. Air Force drones collected roughly 1,800 hours of video a month in Iraq and Afghanistan in 2009, nearly three times as much video than in 2007; sifting through this growing mountain of information is difficult, so the military wants to use the same instant replay technology used in professional football games; after all, U.S. broadcasters handle 70,000 hours daily of video

  • Yarn passes in-vehicle flame test

    Fire in an enclosed space, such as an aircraft, is extremely dangerous as occupants can die from smoke inhalation before there is any danger from the flames. Flame-retardant materials delay the spread of fire, but these typically contain halogenated substances that emit thick black smoke and toxic gases; new material developed which meets halogen-free flame-retardant regulations

  • Study explores the use of terahertz sensors

    New work into the ability of nanometallic or plasmonic structures to concentrate light into deep-subwavelength volumes holds a promise of new applications for terahertz sensors for improving optical sources, detectors and modulators for optical interconnections, and for creating biomolecules

  • Marine camera, integrated software offer improved underwater surveillance, security

    Underwater surveillance is one of the more difficult tasks for security personnel; darkness, humidity, murkiness, low temperature all make it difficult for camera equipment to capture clear images of elements in water; a new marine camera with integrated software offers a solution

  • Combining tiny cave camera, iris recognition technology for military, homeland security

    Researchers are developing new miniature camera technology for military and security uses so soldiers can track combatants in dark caves or urban alleys, and security officials can unobtrusively identify a subject from an iris scan

  • Robots with human-like vision to perform dangerous missions

    Robots with human-like vision may be deployed to perform maintenance inside nuclear fusion reactors or carry out duties in other areas too dangerous for any person to operate in; a new laser sensor is being developed which will mimic this process by obtaining a coarse image of the scene, performing rapid image analysis to detect objects of interest and subsequently obtaining images with higher temporal and spatial resolution of the detected objects
