• Israel, for the first time since the October 1973 war, fires warning shots into Syria

    The civil war in Syria has taken an ominous turn on Sunday as Israel, for the first time since the October 1973 Yom Kippur war, fired into Syria to warn the beleaguered Assad government that Israel would not tolerate shelling from Syrian territory into Israel; on four separate occasions last week, mortars from Syria fell in the Golan Heights, an area Israel captured from Syria in the 1967 war; it appears that the mortar fire was not intentional, but rather stray rounds, the result of errand shelling; on Saturday nine days ago, a few Syrian tanks entered a no-man’s land near the Israel border, in violation of the 1974 cease-fire and force-separation agreement between Israel and Syria

  • U.S.-Iran tensions rise as Iran tries to disrupt U.S. reconnaissance flights in Gulf

    Tensions between the United States and Iran increase as news emerged last week of an attempt by four Iranian fighter planes, on 1 November, to shoot down a U.S. Predator drone engaged in a surveillance mission over international water in the Persian Gulf

  • CIA-commissioned climate change report outlines perils for U.S. national security

    U.S. national security leaders believe that the accelerating pace of climate change will place severe strains on U.S. military and intelligence agencies in coming years; the reason, according the National Research Council, the U.S. top scientific research body: climate changes will trigger increasingly disruptive developments around the world; a 206-page National Research Council study, commissioned by the CIA and other U.S. intelligence services, concludes that states will fail, large populations subjected to famine, flood, or disease will migrate across international borders, and national and international agencies will not have the capacity or resources to cope with the resulting conflicts and crises

  • Supreme Court to hear police DNA-collection case

    The United States Supreme Court last week granted certiorari in Maryland v. King; in the case, Maryland law enforcement stands to lose the right to require a DNA collection as part of booking procedures for certain felony crimes; a similar law was passed by Congress in 2004 for federal arrests, and twenty-four other state legislatures have also passed such laws

  • Cleanup of most contaminated U.S. groundwater sites unlikely for many decades

    At least 126,000 sites across the United States have contaminated groundwater that requires remediation, and about 10 percent of these sites are considered “complex,” meaning restoration is unlikely to be achieved in the next 50 to 100 years due to technological limitations; the estimated cost of complete cleanup at these sites ranges from $110 billion to $127 billion, but the figures for both the number of sites and costs are likely underestimates

  • Nanostructured material stronger than a speeding bullet

    Providing protection against impacts from bullets and other high-speed projectiles is more than just a matter of brute strength; while traditional shields have been made of bulky materials such as steel, newer body armor made of lightweight material such as Kevlar has shown that thickness and weight are not necessary for absorbing the energy of impacts; new tests of nanostructured material could lead to better armor against everything from gunfire to micrometeorites

  • DARPA seeks multi-band, portable sensor to provide soldiers with clear images

    Clip-on or helmet-mounted camera system would fuse useful aspects of visible, near infrared, and infrared images into a single shot under all weather and visibility conditions; the Pixel Network for Dynamic Visualization program, or PIXNET, technology would ingest the most useful data points from each component sensor and fuse them into a common, information-rich image that can be viewed on the soldier’s heads-up display, and potentially be shared across units

  • New strategy for fingerprint visualization

    Identifying fingerprints on paper is a commonly used method in police forensic work, but it is not easy to make those fingerprints visible. Now, scientists have developed a new approach for making such fingerprints more readily readable

  • Flying robot avoids obstacles

    Researchers have created an autonomous flying robot which is as smart as a bird when it comes to maneuvering around obstacles; able to guide itself through forests, tunnels, or damaged buildings, the machine could have tremendous value in search-and-rescue operations

  • DHS grants help Kansas Law enforcement agencies buy new equipment

    DHS grants help local law enforcement agencies fight crime more effectively, but according to some, those same agencies are bypassing military grade surplus equipment for brand new shiny toys

  • "Stutter jump" could improve performance of search and rescue robots

    A new study shows that jumping can be much more complicated than it might seem; in research that could extend the range of future rescue and exploration robots, scientists have found that hopping robots could dramatically reduce the amount of energy they use by adopting a unique two-part “stutter jump”

  • Smart camera to describe what it sees -- and reason about what it cannot see

    Army scouts are commonly tasked with covertly entering uncontrolled areas, setting up a temporary observation post, and then performing persistent surveillance for twenty-four hours or longer; what if instead of sending scouts on high-risk missions the military could deploy taskable smart cameras? A truly “smart” camera would be able to describe with words everything it sees and reason about what it cannot see

  • Approaches to international consequence management for CBRNE incidents

    The National Research Council (NRC) of the National Academy of Sciences, through a grant sponsored by NIST’s Office of Law Enforcement Standards (OLES), is organizing an effort to understand the metrics and measures that are needed to develop standards of response that will support the basic capabilities of a country or region to respond to a chemical, biological, radiological, nuclear, or explosive (CBRNE) incident

  • Technology used in BioWatch could not detect pathogens, issued false alarms

    The BioWatch program was created to detect the release of pathogens in the air as part of a terrorist attack, but scientists say that the program is unable to detect lethal germs because the system uses defective components; these components often set off false alarms; for example, BioWatch sensors issued fifty alarms between 2003 and 2008, but scientists and security authorities never had enough confidence in the BioWatch system to evacuate an area or take other emergency steps

  • CHAMP, Boeing’s non-kinetic alternative to traditional explosive, in first operational test

    CHAMP, Boeing’s counter-electronics weapon system, uses high-powered microwaves to degrade or destroy electronic targets without collateral damage; it was recently successfully passed its first operational test at the Utah desert
