• The arithmetic of gun control and gun violence

    The most comprehensive statistical study of gun violence in the United States – examining data going back to the First World War – finds that, in more common domestic and one-on-one crimes, reduced legal gun availability, if properly enforced, is likelier to lower deaths. In rare mass shootings, armed citizens might save lives if sufficiently trained to avoid accidentally shooting fleeing bystanders. The authors note, though, that key parts of their equations should be studied more closely: the fraction of offenders who illegally possess a gun, the statistical degree of protection provided by legal gun ownership, and the number of people who are legally carrying a gun when attacked. Comprehensive data in those areas, they say, could further aid the development and implementation of effective policies.

  • Research priorities for understanding public health aspects of gun-related violence

    A new report from the Institute of Medicine (IOM) and National Research Council (NRC) proposes priorities for a research agenda to improve understanding of the public health aspects of gun-related violence. The committee which wrote the report said significant progress can be achieved in three to five years through a research program that addresses five high-priority areas: the characteristics of gun violence, risk and protective factors, prevention and other interventions, gun safety technology, and the influence of video games and other media.

  • Humanoid robot ready for DARPA’s Robotics Challenge trials

    A Korean research institution joins with nine U.S. universities to enter the team’s DRC-HUBO, a humanoid robot, in DARPA Robotics Challenge (DRC). The competing robots will have to fulfill eight tasks at the competition, among them driving a utility vehicle, walking across rough terrain, climbing a ladder, and using hand tools.

  • Ukrainian man in U.K. court charged with anti-Muslim terrorism

    Pavlo Lapshyn, a 25-year-old postgraduate student from Dnipropetrovsk, Ukraine, appeared in a Westminster, U.K. court Tuesday and charged with the terror-related April murder of an 82-year-old Mohammed Saleem as Saleem was walking home from a mosque. Lapshyn has also been charged with three additional offenses related to three explosions near mosques in Walsall, Wolverhampton, and Tipton.

  • Bloomberg vetoes bills aiming to curb NYPD’s stop-and-frisk

    New York City mayor Michael Bloomberg vetoed two bills aiming to limit the NYPD’s stop and frisk policy. The policy has been criticized by civil rights advocates, and has also been highlighted by those opposing Police Commissioner Ray Kelly’s candidacy to replace Janet Napolitano as DHS secretary.

  • Non-toxic fire retardants developed

    Fire retardants are often extremely harmful to health. Despite this, they are found in many types of synthetic materials which would otherwise ignite quickly. Researchers have now succeeded in producing non-harmful flame retardants.

  • Using invasive trees to develop jet fuel for U.S. Navy fighter jets

    In western U.S. rangelands, native juniper and pinyon pine trees are spreading beyond their historical ecological niches and disrupting the environmental balance of their expanded range. Preliminary estimates suggest harvesting some of these hardy invaders every year could supply enough biomass to produce millions of gallons of renewable jet fuel for the U.S. Navy fighter jets.

  • Are nuclear weapons safe from cyber-attacks?

    Research will look into whether today’s nuclear weapons are safe from computer hacking. Specifically, the research seeks to address the question of whether the ability to use and the confidence in nuclear weapons is being eroded by new cyber capabilities being developed by an increasingly large range of actors.

  • New underwater robots mimic designs found in nature

    In recent years, robotic underwater vehicles have become more common in a variety of industrial and civil sectors. Now, a new class of underwater robot has emerged that mimics designs found in nature. These “biomimetic” vehicles promise to lead to new underwater technologies that could help the oil and gas industry, underwater humanitarian demining, environmental monitoring, search and rescue operations, anti-terrorist activities, harbor surveillance, coastal security and fisheries management, and more.

  • Young engineers compete in underwater robotics race

    Student-built autonomous underwater vehicles will speed through the depths of a Navy pool in a battle for supremacy at the 16th International RoboSub Competition. The competition is being held this week (22-28 July). In addition to building autonomous underwater vehicles, teams are also responsible for creating Web sites and writing journal papers that outline their work.

  • Hollow-core optical fiber to enable high-power military sensors

    The intensity of light that propagates through glass optical fiber is fundamentally limited by the glass itself. A novel fiber design using a hollow, air-filled core removes this limitation and significantly improves performance by forcing light to travel through channels of air, instead of the glass around it. DARPA’s spider-web-like, hollow-core fiber design is the first to demonstrate single-spatial-mode, low-loss and polarization control — key properties needed for advanced military applications such as high-precision fiber optic gyroscopes for inertial navigation.

  • Angry lawmakers warn NSA to curb surveillance operations

    John Inglis, the deputy director of the National Security Agency (NSA), told angry lawmakers yesterday that his agency’s ability to analyze phone records and online behavior is greater than what the agency had previously revealed. Inglis told members of the House Judiciary Committee that NSA analysts can perform “a second or third hop query” through its collections of telephone data and Internet records in order to find connections to terrorist organizations. Representative James Sensenbrenner (R-Wisconsin), the author of the 2001 Patriot Act, warned the intelligence officials testifying before the committee that unless they rein in the scope of their surveillance on Americans’ phone records, “There are not the votes in the House of Representatives” to renew the provision after its 2015 expiration. “You’re going to lose it entirely,” he said.

  • Automatic license plate readers used to collect, store data on millions of Americans

    Automatic license plate readers are the most widespread location tracking technology available to law enforcement. Mounted on patrol cars or stationary objects like bridges, they snap photos of every passing car, recording their plate numbers, times, and locations. At first the captured plate data was used just to check against lists of cars law enforcement hoped to locate for various reasons (to act on arrest warrants, find stolen cars, etc.). Increasingly, however, all of this data is being fed into massive databases that contain the location information of many millions of innocent Americans stretching back for months or even years.

  • Highly sensitive fingerprint technique developed

    Researchers have developed a new and extremely sensitive method for visualizing fingerprints left on metal surfaces such as guns, knives, and bullet casings. The technique utilizes color-changing fluorescent films and the researchers say that it can be used to complement existing forensic processes.

  • Thermal imaging could bolster biometric security

    Fingerprints and iris recognition will soon give way to thermal imaging.The pattern of blood vessels located just beneath the skin of a person’s face can be isolated using an infrared thermal imaging camera. The blood vessel patterns are as unique as a fingerprint and iris, but are almost impossible to forge.
