• Israel tests advanced Arrow 3 missile defense

    Israel and the United States have jointly tested the Arrow 3, a ballistic missile defense system designed to intercept enemy missiles outside the atmosphere. The Arrow 3 is the fourth component of Israel’s layered missile and rocket defense system, which also includes Iron Dome, David’s Sling, and Arrow 2. The Arrow 3 was designed to intercept missiles outside the atmosphere.

  • Tennessee considers ways to raise money for homeland security

    A 2011 bill gave the Tennessee government the ability to revoke the license of anyone in the state who did not pay criminal fines and court costs. Lawmakers originally hoped the law would bring millions of dollars in reinstatement fees, money which would be directed to the Tennessee Department of Safety and Homeland Security. Only nine counties are complying with the law by notifying the state of violators, and so far the state had collected just $22,425.

  • Cockroaches gait informs search-and-rescue robot design

    More than 70 percent of Earth’s land surface is not navigable by wheeled or tracked vehicles, so legged robots could potentially bridge the gap for ground-based operations like search and rescue and defense. New insights on how cockroaches stabilize could help engineers design steadier robots for operating on difficult terrain.

  • Computers, data help police prevent violence

    As cities across America work to reduce violence in tight budget times, new research shows how they might be able to target their efforts and police attention — with the help of high-powered computers and loads of data. These computers offer detailed analysis of drugs, alcohol, and crimes across a city, helping target crime prevention.

  • Battle-tested technologies no employed by the police

    Technologies employed in the wars in Iraq and Afghanistan are now hitting local streets across the United States, changing how local law enforcement investigates crimes by focusing on where crimes are most likely to happen instead of where a crime has taken place.

  • Background checks should be required for all firearm transfers: study

    In 2012, there were an estimated 467,321 firearm-related violent crimes in the United States, a 26 percent increase since 2008. There were 11,101 firearm homicides that year, and an estimated 55,544 injuries resulting from gun-related assaults requiring treatment in hospital emergency departments. Individuals who buy firearms from a license dealer must undergo a background check, but 40 percent of U.S. gun transactions are exempt from background checks because they occur between unlicensed private parties, such as people buying and selling at gun shows. That figure doubles, to more than 80 percent, for firearm sales that involve criminal intent.

  • Climate change as a national security issue

    In a new report, Harvard researcher is pointing toward a new reason to worry about the effects of climate change — national security. During the next decade, the report concludes, climate change could have wide-reaching effects on everything from food, water, and energy supplies to critical infrastructure and economic security. “The imminent increase in extreme events will affect water availability, energy use, food distribution, and critical infrastructure — all elements of both domestic and international security,” the report’s author says.

  • New explosives vapor detection technology

    Novel explosives detection method focuses on direct, real-time vapor detection rather than collection of explosives particles. It could change paradigm for explosives screening.

  • Defusing the threat of ionizing radiation

    The damage to Japan’s Fukushima nuclear reactor after the 2011 Tohoku earthquake raised concerns regarding U.S. preparedness to treat large-scale human exposure to ionizing radiation. Additionally, the immediate destructive potential of nuclear and radiological weapons, as well as their long-term health and economic impacts, continue to be of concern to DoD. Researchers look for  novel approaches to mitigate immediate and long-term health damage from acute exposure to ionizing radiation and model its biophysical effects.

  • Colorado moving closer to imposing tighter gun restrictions

    Colorado, home of two of the worst mass shooting in United States history, is moving a step closer to passing a new set of gun restrictions. Last Friday, Colorado’s House of Representatives gave approval to legislations which will require background checks for private gun sales as well as limits on clip capacity. Other measures are being considered

  • DHS to buy 1.6 billion rounds of ammunition

    DHS is looking to buy more than 1.6 billion rounds of ammunition in the next four or five years — this comes to about five bullets for every person in the United States. The news was met in some conspiratorial quarters as an indication that the government is in an “arms race against the American people,” but the truth is more mundane: the rounds will be used for basic and advanced law enforcement training for federal law enforcement agencies supervised by DHS. The training will be conducted Federal Law Enforcement Training Center in Glynco, Georgia and other facilities, which also offer firearms training to tens of thousands of federal law enforcement officers.

  • Ohio country authorized to use drones to look for missing persons

    The Medina County, Ohio, Sheriff’s Office has recently been authorized to fly drones on police missions. Tom Miller, the county’s new sheriff, said the drones will be used specifically for looking for missing people or suspect who may be hiding in the woods.

  • DHS HQ cafeteria employee claims she was repeatedly raped on the job

    A cafeteria employee claims she was sexually assaulted and raped several times at the cafeteria of the DHS headquarters building in Northwest Washington, D.C. The D.C. police is now investigating.

  • Alabama consolidates state law enforcement, IT agencies

    A Republican-led effort to consolidate government operations in Alabama was met with a bi-partisan approval as both Democrats and Republicans voted to merge law enforcement and information technology operations. A study done by Auburn University at Montgomery estimates state agencies spend $317 million a year on IT operations, and that with the new measures, the state could save between $32 million and $64 million.

  • Jumping soft robots avoid obstacles during search and rescue operations

    See video

    These soft robots can already stand, walk, wriggle under obstacles, and change colors. Now researchers are adding a new skill to the soft robot tool kit: jumping. Researchers make the robots jump by using combustible gases. This ability to jump could one day prove critical in allowing the robots to avoid obstacles during search and rescue operations.
