• Quantum radar can detect stealth aircraft

    A prototype quantum radar that has the potential to detect objects which are invisible to conventional systems has been developed by an international research team. The new breed of radar is a hybrid system that uses quantum correlation between microwave and optical beams to detect objects of low reflectivity such as cancer cells or aircraft with a stealth capability. Because the quantum radar operates at much lower energies than conventional systems, it has the long-term potential for a range of applications in biomedicine including non-invasive NMR scans.

  • New document details U.S.-Iran cyber tit-for-tat

    Just as U.S. Secretary of State John Kerry and his Iranian counterpart discuss plans to ensure Iran does not weaponized its nuclear program, a newly disclosed National Security Agency (NSA) document details the intensifications of cyber skirmishes between the two countries. While the document does not describe the specific targets in Iran, it acknowledges, for the first time, that the NSA’s attacks on Iran’s nuclear program, a George W. Bush administration project, initiated the cycle of retaliation and escalation of the U.S.-Iran cyber conflict.

  • DHS intelligence assessment highlights threat posed by sovereign citizen groups

    U.S. security officials have long considered sovereign citizen groups as a growing threat to domestic security. In a 2014 surveyof state and local law enforcement agencies, leaders of these agencies listed members of sovereign citizen groups as the top domestic terror threat, ahead of foreign Islamist or domestic militia groups. The U.S. government has primarily focused its counterterrorism efforts on the threats posed by foreign extremist groups, including Islamic State and al-Qaeda, but the problem posed by domestic would-be terrorists has not been overlooked. A new DHS intelligence assessment, released earlier this month, focuses on the domestic terror threat from sovereign citizen extremists.

  • More resilient mass transit to improve Chicago emergency evacuation system

    A group of Argonne Lab researchers will be studying methods and creating tools for building more resilient mass transit systems to evacuate major cities under a $2.9 million grant announced today by the U.S. Department of Transportation’s Federal Transit Administration. The project will bring together researchers from the Department of Energy’s Argonne National Laboratory with Chicago’s Pace Suburban Bus and Metra Commuter Rail Service to investigate ways to improve the detection, analysis, and response to emergencies, and how best to evacuate the city in a major emergency.

  • Social media help alert students during campus emergencies: Study

    Using social networking sites like Facebook and Twitter to spread information during campus emergencies can help keep students safer, according to new research. The study found the widespread popularity of social media and associated mobile apps enables campus authorities to instantly reach a large percentage of students to provide timely and accurate information during crisis situations.

  • Redesigning wild-land fire fighter uniforms

    The most common cause of injuries to wild-land firefighters is not burns. When leaders at the California Department of Forestry and Fire Protection (CAL FIRE) noticed their wild-land firefighters were experiencing more heat stress injuries — like heat exhaustion and heat stroke — than burn injuries, they wanted to know why and how to prevent them. They soon realized their uniforms were part of the problem. Working with a team at the University of California, Davis, they developed technical and design specifications for a new uniform aimed at increasing the comfort and breathability while maintaining the current level of protection against flames. In 2011, CAL FIRE approached the Department of Homeland Security Science and Technology Directorate’s (S&T) First Responders Group (FRG) requesting assistance in developing prototype garments.

  • Kouachi intelligence failure: The struggle to balance security, privacy, budgetary concerns

    About seven months before the attacks on the Paris office of Charlie Hebdo, French domestic intelligence agency monitored Saïd Kouachi for at least two years, and his younger brother Chérif Kouachi for at least a year. The surveillance of both brothers had led nowhere, and was later considered a non-priority for intelligence officials. The Kouachi brothers did not appear to be an imminent threat, and it would have taken twenty-five agents to monitor the two brothers around the clock. Experts say that the failures and missteps by French law enforcement in the Kouachi case should be a lesson to other Western governments which may have relaxed surveillance practices targeted at would-be terrorists in order to comply with budget cuts or out of genuine concern for civil liberties.

  • Hair dye “CSI” could help police solve crimes

    Criminals with a penchant for dyeing their hair could soon pay for their vanity, as scientists have found a way to analyze hair samples at crime scenes to rapidly determine whether it was colored and what brand of dye was used. Researchers showed that surface-enhanced Raman spectroscopy (SERS) could be used rapidly to confirm whether hair samples, even microscopic ones, were dyed and what brand of colorant was used.

  • White House summit on extremism focuses on lone wolves

    Today the White House will host community leaders and local law enforcement officials for the second day of a summit on “countering violent extremism,” the purpose of which is to highlight domestic and international efforts to prevent extremists from radicalizing and recruiting individuals or groups in the United States and abroad to commit acts of violence. The administration’s counter extremism efforts reflect an understanding that lone wolf terror acts will continue to be a threat for law enforcement as much as acts by organized groups such as al-Qaeda.

  • Surveillance blimps raise privacy concerns

    Some 10,000 feet in the air above the Aberdeen Proving Ground in Maryland, the Pentagon has been testing its Joint Land Attack Cruise Missile Elevated Netted Sensor System (JLENS), meant to identify low-flying cruise missiles within a few hundred miles. Supporters of the program say that as cruise missiles become more widely available to U.S. enemies, the aerostats will become a preferred defense option, providing long-range radar much more consistently and cheaply than systems mounted on planes.Privacy advocates question whether privacy rights are being violated in the process.

  • Improved fire detection with new ultra-sensitive, ultraviolet light sensor

    Currently, photoelectric smoke sensors detect larger smoke particles found in dense smoke, but are not as sensitive to small particles of smoke from rapidly burning fires. Researchers have discovered that a material traditionally used in ceramics, glass and paint can be manipulated to produce an ultra-sensitive UV light sensor, paving the way for improved fire and gas detection.

  • U.S. curbing intelligence sharing with Israel as discord over Iran talks deepens

    As a result of the growing tensions between the United States and Israel, and what the United States views as an improper use by Prime Minister Benjamin Netanyahu of sensitive information regarding the nuclear negotiations between the P5+1 and Iran, the White House last week begun to limit the scope, quality, and depth of the information it shares with Israel regarding the talks with Iran about the Iranian nuclear program. A senior Israeli official said that U.S. representatives continue to meet with and update their Israeli counterparts, but are passing on information about the talks “at a lower resolution.”

  • Lone-wolf domestic terrorism on the rise

    As the White House prepares to host a major summit this week examining the threat of violent extremism, a new study of domestic terrorism released last week finds that the vast majority of this violence is coming from “lone wolves” or “leaderless resistance” groups composed of no more than two people. The report examines more than sixty domestic terror incidents. Almost three-quarters of the incidents were carried out, or planned, by a lone wolf, a single person acting without accomplices. Ninety percent of the incidents were the work of no more than two persons.

  • Earthquake early-warning system to be deployed in Washington, Oregon

    California has been testing ShakeAlert, an earthquake early-warning system. Emergency officials and first responders in Washington and Oregon have been working with their counterparts in California to design a similar system specifically for the Pacific Northwest. The project, estimated to cost roughly $16 million a year, has received $6 million from a private foundation, $5 million from Congress for the coming year, and the White House’s new budget calls for another $5 million.

  • Railway stations should adopt some of the security strategies deployed by airports: Experts

    A 2013 study by the U.K. Home Officerecorded crime rates across every postcode in England, Wales, and Northern Ireland, and found that four of the top ten U.K. crime hot spots are major railway stations. Railway stations experience large volume of crime due to their highly congested environments, which gives pickpockets and thieves opportunities to find a target. Large stations are also introducing more retail outlets, which increases the likelihood of more shoplifting offenses. Experts note that airports have many of those same characteristics, but they fare far better in crime rates. These experts argue that rail stations should adopt some of the strategies deployed by airports around the world.
