• DHS debars scanner maker from government contracts

    The Transportation Security Administration (TSA) has sent OSI Systems, the manufacturer of airport body scanners, a debarment notice which would prevent the company from receiving government contacts in the future. The notice was sent to the company after TSA determined that the company had failed to address security concerns about its scanners.

  • Oregon drills first responders for bioterrorism attack

    A three day drill called the Portland Area Capabilities Exercise (PACE), simulating a terrorist attack involving a biological weapon, will take place across fifty different facilities and sixty-five jurisdictions in the state of Oregon.

  • Ricin can kill, but there are more potent bioterror weapons

    Ricin was in the headlines a few weeks ago, when envelopes containing the poison were mailed to President Obama, Senator Roger Wicker (R-Mississippi), and a Mississippi judge. The threat from ricin is low, however, because ricin cannot poison someone through contact with the skin. To be poisoned, an individual would have to ingest or inhale traces of the poison.

  • Quickly identifying chemical, biological warfare agents

    For more than fifty years, researchers have been studying exactly how aspirin affects the human body. Despite thousands of publications on the topic, our understanding is still incomplete. Meanwhile, novel chemical and biological weapons have historically been mass produced within a year of discovery. Using current methods and technologies, researchers would require decades of study to gain a robust understanding of how new threat agents exert effects on human biological systems. DARPA wants to close this capability gap, which leaves U.S. forces vulnerable.

  • Pennsylvania emergency professionals receive WMD training

    The Center for Domestic Preparedness (CDP) in Alabama hosted more than a hundred emergency professionals from the Pennsylvania South Central Mountains Regional Task Force’s Health and Medical Committee for in-depth response-to-WMD training.

  • Terahertz technology helps to see more with less

    Terahertz technology is an emerging field which promises to improve a host of useful applications, ranging from passenger scanning at airports to huge digital data transfers. Terahertz radiation sits between the frequency bands of microwaves and infrared radiation, and it can easily penetrate many materials, including biological tissue. The energy carried by terahertz radiation is low enough to pose no risk to the subject or object under investigation.

  • Reducing the volume of nuclear waste

    The nuclear industry seeks to minimize the volume of nuclear waste by extracting the radioactive elements from spent fuel.This relies on exploiting differences in the chemical bonding of uranium. Scientists have found that in some circumstances the bonding may be surprisingly similar, an important discovery which is going to be important in the amelioration of nuclear waste clean-up and devising new atom-efficient catalytic cycles.

  • U.S. sharply disputes UN official's claim that Syrian rebels used chemical weapons

    The United States sharply challenged claims by a UN official – who is not a member of the UN investigative commission looking into to the possible use of chemical weapons in Syria – that the rebels, rather than the Assad regime, used sarin nerve gas near the city of Aleppo on 19 March. The UN investigative commission looking into the incident distanced itself from the official’s comments.

  • U.S. policy may lead to growing global shortage of helium

    Helium is an essential resource in technologies such as medical imaging, rocket engines, and surveillance devices. In response to the element’s scarcity, the United States has been stockpiling helium since the 1960s in a National Helium Reserve called the Bush Dome, a deep underground reservoir outside of Amarillo, Texas. In 1996 the Helium Privatization Act mandated that the Department of the Interior sell off all the stockpiled helium by 2015. Scientists say that this action discourages the active exploration of helium since companies can buy it from the United States at a cheap price and sell it at a premium. The result will be a growing shortage of helium.

  • 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). The police in Kenya purchased twenty-six of the sham detectors, but Nairobi police chief says the devices work, and that Kenya is safer for them.

  • 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.

  • 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.

  • Ammonium nitrate fertilizers are inherently risky, but the benefits are many

    The deadly explosion has brought the $10 billion U.S. fertilizer industry to the attention of the mainstream media, but the risks inherent in fertilizer production and storage are not a secret to people close to the industry. Ammonium nitrate may be dangerous, but its benefits cannot be ignored.

  • New detection test to improve food safety, bioterrorism defense

    Sales of chicken products in China plummeted recently during an outbreak of a deadly new strain of bird flu. From bird flu to mad cow disease, numerous food scares have made global headlines in recent years.Scientists develop new detection technique which wouldmake food contamination testing more rapid and accurate. The detection test could also accelerate warnings after bioterrorism attacks.

  • Mississippi man arrested for sending ricin letters to Obama, Sen. Wicker

    The FBI confirmed yesterday (Wednesday) that a letter addressed to President Obama was found to contain the toxin ricin. As is the case with all the mail sent to the White House, the letter was screened in a remote mail sorting facility in Anacostia, a neighborhood in southeast Washington, D.C., and intercepted. The FBI arrested a man from Tupelo, Mississippi, on suspicion that he was behind the ricin letters to the White House and to Senator Roger Wicker (R-Mississippi), who lives in Tupelo.
