  • Central Washington State proposed for a UAV research and testing site

    The FAA Modernization and Reform Act of 2012 enacted by Congress calls for establishing six unmanned aircraft system research and testing sites in the United States. A consortium of Washington State-based organizations will soon submit the final section of a proposal to site an unmanned aircraft system research and testing facility in central Washington.

  • Seeking new ideas for mobile ad hoc networks (MANETs)

    Troops operating in forward locations without telecommunication infrastructure often rely on a mobile ad hoc network (MANET) to communicate and share data. A constraint with current MANETs is they can only scale to around fifty nodes before network services become ineffective. DARPA is exploring new technologies unencumbered by Internet Protocols (IP) which could be the key to enabling large MANETs. The Internet facilitated far-reaching technical advances, but in this technology area the Internet may be the roadblock.

  • Kenya police: (fake) bomb detectors work, making Kenyans safer

    A British businessman was convicted of selling Iraq and Afghanistan fake bomb detectors – the two countries used millions of dollars in U.S. aid money to purchase the sham devices (the devices were, in fact, $20 golf ball finders which the businessman sold for $40,000 each).

  • U.K. businessman convicted of selling fake explosives detectors

    James McCormick, a British businessman, was convicted of having made millions in profits from selling fake bomb detectors to Iraq, Georgia, and several other countries. McCormick bought $20 golf ball finders in the United States, then sold the devices, which had no working electronics, for $40,000 each. The Iraqi government used more than $40 million in U.S. aid money to buy 6,000 of the devices, despite being warned by the U.S. military that the devices were a sham. The Iraqi military used the fake detectors at check-points, leading to scores of soldiers and civilians being killed by suicide trucks which went through the check points undetected. The police in Kenya says it will continue to use the devices.

  • California considering lead ammo ban

    Health and environmental advocates are trying to make California the first state to enforce a statewide ban on the use of lead bullets for hunting. The U.S. Geological Survey (USGS) estimates that there are 400,000 pieces of lead shot per acre in wild game territory which can be eaten or washed into rivers and waterways. The USGS also says that 60,000 metric tons of lead fired off last year is the second largest use of lead in the United States behind batteries. The CDC reports that lead is so abundant in meat harvested through hunting, that pregnant woman and children should never eat it. The NRA opposes the ban, saying it could possibly the end of hunting in California.

  • New fertilizer can be used to grow food – but not build bombs

    Ammonium nitrate fertilizer is used in agriculture, but when mixed with a fuel such as diesel, it is highly explosive. It was used in about 65 percent of the 16,300 homemade IEDs in Afghanistan in 2012.About 1,900 troops were killed or wounded in IED attacks in 2012, 60 percent of American combat casualties. There have been more than 17,000 global IED incidents in 123 countries in the past two years. Timothy McVeigh used ammonium nitrate in Oklahoma City in 1995. Scientists have developed a fertilizer that helps plants grow but cannot detonate a bomb.
