• Chernobyl radiation did not damage abundance, diversity of aquatic life

    A new study of the lakes in and around Chernobyl’s fallout zone reveals that radiation from the nuclear accident appears to have had no long term effect on the abundance or diversity of aquatic animal life; no evidence was found that the abundance or diversity of the animal communities was influenced by direct contamination from the Chernobyl accident; indeed, the most contaminated lake, Glubokoye, 6.5 km north of the nuclear power plant, supported the most animal diversity of those lakes studied

  • Space technology of practical uses on Earth

    Terahertz technology developed for space missions to study the most distant objects in the universe is now finding a host of practical applications back on Earth; most clothing and packaging materials are transparent to Terahertz radiation, whereas skin, water, metal and a host of other interesting materials are not; this gives rise to some important day-to-day applications: detecting weapons concealed under clothing or inside parcels; distinguishing skin and breast cancer tissue; quality control of manufactures items and processes in factories

  • Trees as contamination detectors

    Determining the presence and concentration of contaminants has been an invasive, laborious process; now a Missouri University of Science and Technology team has developed a faster, more economical method of determining such contamination at miniscule levels; the Army has funded additional research for explosive residue detection

  • New material cleans water of radioactive contamination

    NC State researchers develops material to remove radioactive contaminants from drinking water; the material is a combination of forest byproducts and crustacean shells; the new material not only absorbs water, but can actually extract contaminates, such as radioactive iodide, from the water itself; this material, which forms a solid foam, has applications beyond radioactive materials

  • NRC inspects Nebraska reactor radiation exposure

    On 3 April, workers at the Cooper Nuclear Station, located near Brownville, Nebraska removed a long tube contaminated with highly radioactive material through the bottom of the reactor vessel, rather than through the top as is usually done, triggering radiation alarms; the NRC is investigating

  • DHS: U.S. unprepared for nuclear disaster

    Confidential DHS report says the United States is ill-prepared for a nuclear disaster — either an accident or a terrorist attack; just one example: if a major nuclear bomb were to hit Washington, D.C., there would be a need for about 61,000 beds in intensive care units; there are, however, only 118,000 intensive care beds in the entire United States and, on any given day, only 9,400 are free.

  • Army seeks long distance explosive detection scanners for people

    The U.S. Army is seeking to rapidly deploy long distance chemical detection devices that are capable of detecting explosives hidden on people; ideally, the devices will be able to sense the presence of explosives and chemicals on people standing, walking, or running from as far away as 100 yards; the Army wants to be able to field these capabilities within a year, so it is only considering mature technologies that are ready to be implemented; the request for proposals will close on 6 May

  • Russia to employ hi-tech bomb-sniffing dog

    In response to a series of terrorist attacks, Russia’s president Dmitry Medvedev has called on Russian military and security services to train more dogs as bomb sniffers; the dogs are trained not only in identifying explosives, but are also trained in carrying walkie-talkies so they can be given instructions from a distance, and to carry portable video cameras for in-building surveillance

  • Spate of dry-ice bombs explosions in Long Beach, Calif.

    A Long Beach officer is injured after an investigation of a dry-ice bomb left in an alley; a dry ice bomb is a homemade device that uses water, a bottle and dry ice, or frozen carbon dioxide; it can take anywhere from thirty seconds to an hour for a dry-ice bomb to rupture, depending on temperatures outside of the bottle

  • Concerns about Illinois nuclear safety trigger inspections

    The U.S. Nuclear Regulatory Commission (NRC) is currently performing Special Inspections at the Byron and Braidwood Nuclear plants in Illinois after issues were identified in February and March of 2011; at issue is the ability of pumps to cool the reactor in case of a reactor trip or any reason the system for heat removal became unavailable at both Byron and Braidwood stations which are similar in design

  • Easing contamination fears in Japan's food industry

    With much of Japan’s manufacturing sector, land, and critical infrastructure badly damaged from the March 11 earthquake and tsunami, dairy and rice manufacturers have struggled to produce enough to feed the nation; Japan produces all of its own milk, rice, and yogurt products, but domestic plants are operating far below full capacity; shortages may persist into the summer; as production ramps up, fears of contamination from radiation leaked from the Fukushima Daiichi nuclear power plant may dampen consumption; one analyst suggests that Japan institute a food tracking program that will allow consumers to track the production of food every step of the way to help ease fears

  • Battery-less chemical detector developed

    Conventional chemical detectors require an external power source, but Lawrence Livermore researchers have developed a nanosensor that relies on semiconductor nanowires rather than traditional batteries; the device overcomes the power requirement of traditional sensors and is simple, highly sensitive, and can detect various molecules quickly; its development could be the first step in making an easily deployable chemical sensor for the battlefield

  • New device uses sniffer bees to detect explosives

    The unassuming honeybees have a hidden talent — an even keener sense of smell than anyone first expected — which could make them one of the U.K.’s most ruthless and worst-feared weapons against terrorism; researchers developed a portable handheld sensor that holds thirty-six trained bees gently restrained in six cassettes inside the device; each is taught to recognize a particular odor and associate that smell with a food reward; the researchers have already trained their honeybees to detect a wide variety of explosive compounds and mixtures, including Semtex, C4, PE4, TNT, DMNB, gunpowder, and hydrogen peroxide

  • Ultra-sensitive sensor technology detects explosives, cancer

    Princeton researchers have invented an extremely sensitive sensor that opens up new ways to detect a wide range of substances, from tell-tale signs of cancer to hidden explosives; the sensor, which is the most sensitive of its kind to date, relies on a completely new architecture and fabrication technique developed by the Princeton researchers; the device boosts faint signals generated by the scattering of laser light from a material placed on it, allowing the identification of various substances based on the color of light they reflect; the sample could be as small as a single molecule
