  • DamsFeds, Calif. disagree on seismic safety of U.S. tallest dam

    At 742 feet, Oroville Dam in Oroville, California is the tallest dam in the United States. It is 45-year old, and federal inspectors say it needs a comprehensive earthquake safety assessment. The California Department of Water Resources (DWR) insists that the dam, which holds 3.5 million acre-feet of water, is safe, and that such an assessment would be an “unjustified expense.” David Gutierrez, chief of California Division of Safety of Dams (DSD), says his agency will decide in January 2014 whether earthquake assessments will be made, but notes: “Oroville is not one that keeps me up at night from a seismic stability standpoint.”

  • Airport screeningAirport screeners miss unusual – and possibly dangerous -- items

    A smartphone app that turns gamers into airport baggage screeners is showing that finding weapons and other illegal items is not all that easy, even when you are looking for them. Researchers analyzed data from searches of twenty million virtual suitcases in the game Airport Scanner created by Kedlin Co. and found that users failed in most cases to identify objects that occurred only rarely. The reason: Commonly found objects may be crowding out identification of the unusual items.

  • Modeling terrorismGame theory helps corporate risk manage analyze terrorism risks

    The challenges of modeling and analyzing terrorism risk are based on the reality that the adversary is one who can alter where and when to strike and has the capability to counter-attack. Before 9/11, the science of risk modeling and analysis for corporations was primarily based on data accumulated from Mother Nature, a less responsive actor. Risk models have become more precise, but this increased precision notwithstanding, terrorists are likely to act in unexpected ways. To anticipate those unexpected ways, risk managers are relying on game theory, with the assumption that exploring hypothetical situations will prepare risk managers for the unexpected.

  • SurveillanceU.S., U.K. intelligence worried about Snowden’s “insurance policy” cache

    Edward Snowden has so far released about 500 of the classified documents he secretly downloaded while working for an NSA contractor. Source familiar with the case say he had downloaded between 50,000 and 200,000 classified NSA and British government documents. Those close to him suggest that in addition to continuing a steady release of secret documents over the next two to three years, the potentially most damaging information he obtained, information which includes the names of thousands of intelligence agents and informers employed by the United States and its allies, is kept in a secret cache as an insurance policy against arrest or physical harm.

  • Surveillance Surveillance programs prompt start-up entry into privacy protection market

    Revelations of the surveillance programs of the National Security Agency(NSA) and the U.K. Government Communications Headquarters(GCHQ) have sparked technical innovations, legal challenges, and pursuits of political reforms in the United States and Britain. While some established providers of secure e-mails have bowed out, new companies are moving in to offer consumers protection from prying.

  • African securityUN approves intervention in Central African Republic as violence rages

    The UN Security Council yesterday voted for a resolution, put forward by France, which authorized an African Union-led peacekeeping force to intervene in the Central African Republic to prevent the growing chaos from causing the state to disintegrate. The AU force, with the support of French forces, will protect civilians, restore humanitarian access, and stabilize the country. UN officials have warned that the violence between the Christian majority and Muslim minority now in power could lead to genocide.

  • RoboticsStandardized performance tests for emergency response robots

    Seventeen teams will be directing their emergency-response robots to perform eight basic tasks which were drawn from the Fukushima Daiichi response and then converted into standardized tests by researchers at the National Institute of Standards and Technology (NIST). A year later, the capabilities of robots that qualify in this year’s trials will be tested in a more realistic disaster scenario. In the winner-take-all finals, robots will perform all eight challenges consecutively. NIST engineers have been at the forefront of using standardized performance testing for emergency response robots used in bomb-response and for urban search-and-rescue operations. Since 2005, fifteen NIST tests have been adopted as standards by ASTM International, and about forty more are under various stages of development or review.

  • EarthquakesEarthquake early warning? There’s an app for that

    Researchers from the University of California have unveiled a smartphone app designed to provide users an early warning of approaching earthquakes. Based on the proximity of the user to the earthquake’s epicenter, the app will provide alerts of between a few seconds and one minute before a tremor hits.

  • EarthquakesBetter earthquake early-warning system

    Geophysicists have developed a new way of calculating the magnitude of an imminent earthquake by making better use of measurements of the compression waves produced early in the event. They say that the technique could be used to create a better early-warning system for earthquakes that could be used worldwide.

  • Radioactive poisoningStolen nuclear material found intact in Mexico

    Mexican police yesterday said they have found a truck, a white 2007 Volkswagen cargo vehicle, which was stolen Monday by thieves who apparently were not aware that it was carrying toxic radioactive medical material from a hospital to a disposal site. The cobalt-60 the truck was carrying could be used to build a “dirty bomb.” The IAEA said that more than 100 incidents of thefts and other unauthorized activities involving nuclear and radioactive material are reported to the agency annually.

  • Radioactive poisoningYasser Arafat was not poisoned: French investigators

    French scientific and medical experts rule out possibility that Palestinian leader was poisoned by radioactive polonium-210. A Russian medical team examining tissue samples taken from Arafat’s body reached the same conclusion three months ago. The conclusions of a Swiss medical team were more ambiguous. Leaders of the Palestinian Authority began accusing Israel of poisoning Arafat even before he died, as his health was rapidly declining. Israel has consistently denied the accusation, describing it as “unreasonable and unsupported by facts.”

  • TerrorismHezbollah No. 3 commander gunned down in Beirut

    Hassan al-Laqees, regarded as the third or fourth most important leader of Hezbollah, was gunned down outside his home in Beirut last night. The Shi’a group blamed Israel for the assassination and warned that Israel would pay a price for the killing. Al-Laqees, who had served in various capacities in Hezbollah since the 1980s, was regarded by Western intelligence services as a brilliant technology and logistics officer. He was in charge of the organization’s arms development and acquisition, technology, and communication, and was heavily involved in operations. Analysts compare the operational blow to Hezbollah from al-Laqees’s assassination to the setback the organization suffered when Israeli agent killed Imad Mughniyeh, the then-operation chief of Hezbollah, in a daring covert operation in Damascus on 12 February 2008.

  • Nuclear facilities securityY-12 security breach update: Old nun awaits sentencing while costs of new Y-12 facility not to be released until 2015

    By Robert Lee Maril

    On 28 July 2012, three senior citizens, led by an 83-year old nun, easily breached the supposedly impregnable security systems protecting the Y-12 National Security Complex at Oak Ridge, Tennessee. The three peace activists wondered the grounds of the maximum security facility for a while before being noticed by security personnel. While the three aging protesters are awaiting sentencing, the two companies — Bechtel Corporation and Babcock and Wilcox – which were responsible for designing and implementing security at Y-12, have been named as the primary construction contractors for planning and design of the new uranium processing facility (UPF) to be built at Y-12.

  • No-fly listFirst no-fly list case goes to trial

    Rahinah Ibrahim, dean of the architecture and engineering school at the University of Malaysia, took to trial on Monday her claim against the U.S. government for wrongfully listing her on the government’s no-fly list. Ibrahim has sought to clear her name since January 2005, when she was arrested at San Francisco International Airport. Similar lawsuits are pending across the country, but Ibrahim’s case is the first to go to trial. Ibrahim claims she was mistakenly placed on the no-fly list due to her national origin and Muslim faith.

  • AviationExisting airports through futuristic glass pods

    Two small Northeast airports, Syracuse and Atlantic City, have installed futuristic unmanned portals to replace security officers at the airports’ exit points. The move, which will add a few seconds to the end of passengers’ trips as they exit the airports, is estimated to save airports millions of dollars in wages over time.

  • Infrastructure protectionEarly warning system to detect abrupt climate change impacts

    Climate change has increased concern over possible large and rapid changes in the physical climate system, which includes the Earth’s atmosphere, land surfaces, and oceans. Some of these changes could occur within a few decades or even years, leaving little time for society and ecosystems to adapt. A new report from the National Research Council states that even steady, gradual change in the physical climate system can have abrupt impacts elsewhere — in human infrastructure and ecosystems for example — if critical thresholds are crossed. The report calls for the development of an early warning system that could help society better anticipate sudden changes and emerging impacts.

  • Planetary security Key to protecting Earth from asteroids: time

    Scientists say that humanity can address the threats from asteroids of any size if given enough time and notice of the asteroid’s existence and trajectory. Even an asteroid the size of the 10-kilometer-wide space rock which scientists hold responsible for the extinction of dinosaurs sixty-five million years ago, can be destroyed,  although it would take hitting the asteroid with multiple spacecrafts over a period of several decades.

  • TerrorismQuestions over Texas police linking chewable African plant to terrorism

    Khat is a chewable African plant containing two active chemical substances — cathinone and cathine – which have a narcotic effect. Chewing the plant is common among men in the Horn of Africa and Yemen. The chemicals are banned in the United States, although the plant itself is not. Texas law-enforcement arrested several Muslim immigrants after a lengthy investigation found they were growing and selling khat. The police portrayed those arrested as supporters of terrorism, and suggested that the profits from the sale of khat to Muslims in the Houston area was sent abroad to support terrorist groups such as al-Shabaab. Civil rights advocates say that in this case, over-eager police and prosecution have confused traditional practice with support for terrorism.

  • Electromagnetic pulseDefending against electromagnetic-pulse attacks

    We are all familiar with the power of electromagnetic attacks from the movies: in “Ocean’s Eleven,” George Clooney’s gang disables Las Vegas’ power grid, and Keanu Reeves’ henchmen hold off the enemy robot fighters from their spaceship in the “Matrix Trilogy.” The heroes in the films succeed by sending out a very strong electromagnetic pulse, which changes the voltage in the vicinity so that regulators, switches, and circuit boards in electronic equipment go crazy. Researchers are now trying to figure out how such attacks can be detected. They have developed a measurement instrument for this purpose that is capable of determining the strength, frequency, and direction of electromagnetic attacks.

  • African securityFrance reasserting its role as Africa's indispensable power

    In March this year, rebel militias, many composed of Muslim fighters from Chad and Sudan, overthrew the government, a move which has resulted in spreading lawlessness among rival warlords, with the risk of the disintegration of the country and sectarian war spilling beyond the country’s borders distinct possibilities. As was the case in Mali earlier this year, France has decided to put its foot down, sending hundreds of troops to the capital Bangui to restore order and restrain the lawless rebels. “The challenge of this intervention [in the Central African Republic],” on analyst wrote, “lies in the ‘return’ of France to the dark continent after decades of interference followed by a period of relative indifference or misstatements. If France succeeds in its Central African mission, it will have recovered a good part of its influence, positioning itself as an indispensable partner in those places where it risked becoming a vague memory.”
