• Bomb-detecting lasers to improve security checkpoints

    Research has put the possibility of bomb-detecting lasers at security checkpoints within reach by developing a laser that can detect micro traces of explosive chemicals on clothing and luggage. The laser not only detects the explosive material, but it also provides an image of the chemical’s exact location, even if it’s merely a minute trace on a zipper.

  • New detectors for chemical, biological threats

    In the late 1990s, Sandia scientists developed a simple-to-use handheld chemical detector for the military, the MicroChemLab. Ever since, Sandia has improved such microfluidics- and microelectromechanical (MEMS) systems-based instruments that identify chemicals based on gas chromatography, or GC, and resonator-style instruments such as surface acoustic wave (SAW) detectors. The lab’s researchers are building on this sensor work to invent tiny detectors that can sniff out everything from explosives and biotoxins to smuggled humans.

  • Worries grow about Syria’s biological weapons capabilities, intentions

    The debates among experts in Western and Middle Eastern intelligence services and militaries about the use of chemical weapons by the Assad regime revolve around how many times Assad has used chemical weapons, not whether such weapons were used. Neighbors of Syria have become increasingly alarmed – and, in private, have expressed their anxiety in discussions with the United States – about another illicit Syrian WMD program: biological weapons. The readiness of the Assad regime to use one proscribed weapon – chemicals — has led to growing unease among Syria’s neighbors that the regime may not find it too difficult to violate other weapon-related taboos. Biological weapons could give the Assad regime an effective means of retaliation because, if the weapon is well-designed, the lethal contents would spread easily without leaving tell-tale signs about the origin of the attack – or even evidence that there has been an attack.

  • Administration's Syria plan: limited operation with “downstream” effect

    Three leading administration officials yesterday presented, in general detail, the plan of attack on Syria. The plan emphasizes the destruction of delivery vehicles – missiles, rockets, planes and their airfields, and artillery pieces – used in the delivery of chemical weapons. The three officials – Kerry, Hagel, and Dempsey — agreed that such an attack, even if its purpose would be to degrade the regime’s ability to deliver chemical weapons, would have “downstream” effect: these delivery vehicles also deliver conventional munitions, so their destruction would more generally degrade the regime’s ability to fight, thus making the battlefield between the regime and the rebels more level. The Senate Foreign Relations Committee is today drafting a new resolution which would permit up to ninety days of military action against the Syrian government and bar the deployment of U.S. combat troops in Syria but permit the deployment of a small rescue mission in the event of an emergency. The White House also would be required within thirty days of enactment of the resolution to send lawmakers a plan for a diplomatic solution to end the violence in Syria.

  • British MPs vote against U.K. military participation in attack on Syria

    In a heavy defeat to Prime Minister David Cameron, , the British Parliament voted against British military contribution to or involvement in an attack on Syria in response to the Assad regime’s use of chemical weapons last week. The vote is an embarrassing defeat for Cameron, and a major set-back for President Obama’s plan to put together a coalition of the willing to strike military targets in Syria. The parliamentary vote has no military significance, as the British contribution to the actual military operations would have been minimal at best. The U.K. vote, rather, is a political blow to the United States as it highlights on-going skepticism among Western publics – including U.S. public opinion — about yet another Western military involvement in the Middle East.

  • UN withdraws inspectors from Syria ahead of schedule

    UN secretary-general Ban Ki-moon has instructed the UN weapons inspectors investigating last Wednesday’s chemical weapons attack to leave Syria by Saturday. The withdrawal of UN inspectors in the face of an imminent military campaign is reminiscent of other instances of early departures of UN weapons inspectors from Iraq in December 1998. The Clinton administration tipped the inspectors off that missile strikes against Saddam Hussein’s regime were imminent.

  • Divisions in U.K. over Syria action

    A U.S.-led attack on Syrian targets in response to the Syrian military’s use of chemical weapons in an attack on Sunni civilians last Wednesday may be delayed until next week in the face of strong opposition in the U.K. parliament to British involvement. Prime Minister David Cameron said MPs would be given a second vote to approve military action ahead of a Commons debate today (Thursday) on Syria, in order to defuse a parliamentary revolt. About seventy Tory MPs said they would join the Labor opposition in voting against the U.K. participating in the attack on Syria. Some of the opponents of U.K. participation say a UN approval of such an attack would be needed, while others say they want to see clear-cut proof of the Assad regime’s culpability.

  • Fukushima radioactive plume to reach U.S. next year

    The radioactive ocean plume from the 2011 Fukushima nuclear plant disaster will reach the shores of the United States within three years from the date of the incident, but is likely to be harmless, according to a new study. While atmospheric radiation was detected on the U.S. west coast within days of the incident, the radioactive particles in the ocean plume take considerably longer to travel the same distance.

  • 3D Earth model accurately pinpoints source of earthquakes, explosions

    During the cold war, U.S. and international monitoring agencies could spot nuclear tests and focused on measuring their sizes. Today, they are looking around the globe to pinpoint much smaller explosives tests. Researchers are working on developing a 3-D model of the Earth’s mantle and crust called SALSA3D. The purpose of this model is to assist the U.S. Air Force and the international Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) in Vienna, Austria, more accurately locate all types of explosions.

  • New technology improves IED detection

    Improvised explosive devices, or IEDs, are homemade bombs that can both injure and kill civilians and service members. One solution to the problem of IEDs is to find them before they explode by detecting the chemicals used in the explosives. Scientists at the U.S. Naval Research Laboratory (NRL) have developed a technology, using silicon to fabricate a sensor that may revolutionize the way trace chemical detection is conducted

  • U.S., allies prepare military strikes against Syria

    Secretary of State John Kerry yesterday said that the use by the Assad regime of chemical weapons in attacks on civilians last Wednesday was undeniable. He said the Obama administration would hold the Syrian government accountable for this “cowardly crime” and “moral obscenity.” U.S. political and military leaders have been holding around-the-clock discussions with allies about a coordinated military attack on Syrian regime facilities. The United States, the United Kingdom, France, and Turkey said there was no need to seek a UN Security Council approval of military action against Syria, and that none will be sought. Administration lawyers have been crafting legal justifications for an intervention without UN approval that could be based on findings that Assad used chemical weapons and created a major humanitarian crisis. The U.S. Navy has moved more ships to the eastern Mediterranean, and activity has been stepped up in Britain’s air base in Cyprus.

  • Long-term radiation effects: Chernobyl’s lessons for Fukushima

    The Fukushima Daiichi nuclear disaster spread significant radioactive contamination over more than 3,500 square miles of the Japanese mainland in the spring of 2011. Now several recently published studies of Chernobyl are bringing a new focus on just how extensive the long-term effects on Japanese wildlife might be.

  • Nanoparticles in food pose health risks

    Nanomaterials are increasingly used in water treatment, food packaging, pesticides, cosmetics, and other areas. There is a growing concern that these particles could pose a potential health risk to humans and the environment. In a new study, researchers have developed a reliable method for detecting silver nanoparticles in foods.

  • Boob bombs: breast implants suicide bomb a threat to aviation

    Security checks at Heathrow Airport have been beefed up this past week following “credible” intelligence that al Qaeda operatives may use a new method to attack airlines flying out of London: explosives concealed in breast implants. This would not the first time Al Qaeda in the Arabian Peninsula’s (AQAP) chief bomb maker, Ibrahim al-Asiri, has sought to use the human body as a hiding place for explosives. In September 2009, al-Asiri sent his younger brother on a suicide mission in Saudi Arabia. He built a bomb which could fit in his brother’s anal cavity, and sent him to kill the Saudi deputy interior minister, who at the time was in charge of hunting down al Qaeda operatives in Saudi Arabia. The worry about medically implanted explosives has already led airports to use behavioral analysis to augment detection methods already in use to screen people. Body scanners are good at identifying things outside the body but not inside.

  • New understanding of key step in anthrax infection

    Scientists advance A new hypothesis concerning a crucial step in the anthrax infection process. The research teams have explored the behavior of the toxins that rapidly overwhelm the body as the often-fatal disease progresses. Their findings suggest a new possible mechanism by which anthrax bacteria deliver the protein molecules that poison victims. Anthrax is easily weaponized; the findings could help lead to a more effective cure.
