  • Sandia Labs-developed IED detector being transferred to the U.S. Army

    Though IED detonations have declined in Afghanistan since a peak of more than 2,000 in the month of June 2012, Department of Defense reports indicated IEDs accounted for about 60 percent of U.S. casualties that year. Detecting improvised explosive devices in Afghanistan requires constant, intensive monitoring using rugged equipment. When Sandia researchers first demonstrated a modified miniature synthetic aperture radar (MiniSAR) system to do just that, some experts did not believe it. Those early doubts, however, are gone. Sandia’s Copperhead — a highly modified MiniSAR system mounted on unmanned aerial vehicles (UAVs) — has been uncovering IEDs in Afghanistan and Iraq since 2009. Now, Sandia is transferring the technology to the U.S. Army to support combat military personnel.

  • A farewell to (nuclear) arms: A novel technique could facilitate nuclear disarmament

    A proven system for verifying that apparent nuclear weapons slated to be dismantled contained true warheads could provide a key step toward the further reduction of nuclear arms. The system would achieve this verification while safeguarding classified information that could lead to nuclear proliferation. Their novel approach, called a “zero-knowledge protocol,” would verify the presence of warheads without collecting any classified information at all.

  • Hazardous devices teams to compete at Robot Rodeo

    Hazardous devices teams from around the Southwest will wrangle their bomb squad robots at the eighth annual Robot Rodeo beginning Tuesday, 24 June at Los Alamos National Laboratory.

  • Judge rules use of NSA surveillance-based information in terrorist case is legal

    Lawyers for Mohamed Mohamud, a U.S. citizen who lived in Oregon, have been denied a motion to dismiss his terrorism conviction, with the court affirming the legality of the U.S. government’s bulk phone and e-mail data collection of foreign nationals living overseas. Mohamud’s defense team claimed the surveillance violated his constitutional rights, and that federal prosecutors did not make available to the defense evidence obtained via the surveillance. U.S. District Judge Garr King upheld Mohamud’s conviction, saying that suppressing the evidence collected through NSA surveillance “and a new trial would put defendant in the same position he would have been in if the government notified him of the (surveillance) at the start of the case.”

  • Experts urge deployment of earthquake warning system in California

    Scientists say that California has “99.7 percent chance of experiencing a severe earthquake — magnitude 6.7 or higher on the Richter scale — within the next 30 years.” These scientists are urging Congress to consider funding the full-scale deployment of an early-warning earthquake system on the western coast of the United States following successful testing of a prototype and positive results from similar international systems.

  • OPCW says Syria has completed handover of chemical weapons, but some are skeptical

    Syria handed over the remaining 100 tons of toxic material to the Organization for the Prohibition of Chemical Weapons (OPCW) last Monday. The final consignment, publicly delayed, consisted of about 8 percent of the total 1,300 tons that the country is believed to have possessed. Despite the celebratory mood, many in the West look at the Syrian and OPCW announcements skeptically due to conflicting information.

  • Historic proportions of Iraq’s military collapse raise questions about Iraq’s viability

    “The scale of Iraq’s military collapse is of historic proportions,” one military analyst said. A recent assessment of the Iraqi military found that 60 out of 243 Iraqi Army combat battalions “cannot be accounted for, and all of their equipment is lost.” American military officials said an evaluation of the state of Iraq’s military revealed that five of the Iraqi Army’s fourteen divisions were “combat ineffective,” including the two that were overrun in Mosul. The United States has spent $1.7 trillion in Iraq since 2003, of which $25 billion were used to equip and train the post-Saddam Iraqi military. The United States received no return on its huge investment in Iraq, but it was hoped that at least the Iraqi military, U.S.-trained and U.S.-equipped, would provide a solid, professional foundation for a new Iraq. Developments in Iraq last week proved that this hope was illusory.

  • Engineered enzymes to neutralize deadly effects of chemical weapons

    Researchers are a step closer to creating a prophylactic drug that would neutralize the deadly effects of the chemical weapons used in Syria and elsewhere. The researchers are trying to engineer enzymes — called bioscavengers — so they work more efficiently against chemical weapons.

  • Pentagon’s excess equipment makes local police resemble military units

    In the early 1990s, Congress authorized the Pentagon to transfer excess military equipment to law enforcement agencies across the country for use in counter-drug activities. Since the program’s inception, the Pentagon has transferred $4.3 billion worth of military equipment to local and state agencies. In 2013 alone, $449,309,003 worth of military property was transferred to law enforcement. Critics say that more and more police departments now resemble military units, and that military gear is used in cases where it should not – as was the case in a small Florida town in 2010, when officers in SWAT gear drew out their guns on raids on barbershops that mostly led to charges of “barbering without a license.”

  • Synthetic aperture sonar to help in hunting sea mines

    Mines are plentiful and easy to make. Some mines explode on contact. Others are more sophisticated, exploding or deploying torpedoes when their sensors detect certain acoustic, magnetic or pressure triggers. Some can destroy a ship in 200 feet of water. Since the Second World War, sea mines have damaged or sunk four times more U.S. Navy ships than all other means of attack combined, according to a Navy report on mine warfare. New sonar research could improve the Navy’s ability to find sea mines deep under water. The underlying technology, known as synthetic aperture sonar (SAS), uses advanced computing and signal processing power to create fine-resolution images of the seafloor based on reflected sound waves.

  • Technology allows human to climb like geckos

    Historically, gaining the high ground has always been an operational advantage for soldiers, but the climbing instruments on which they are frequently forced to rely — tools such as ropes and ladders — have not advanced significantly for millennia. DARPA’s Z-Man program has demonstrated the first known human climbing of a glass wall using climbing devices inspired by geckos. The historic ascent involved a 218-pound climber ascending and descending twenty-five feet of glass, while also carrying an additional 50-pound load in one trial, with no climbing equipment other than a pair of hand-held, gecko-inspired paddles.

  • Badly engineered missile defense systems deployed “because there was a rush”

    In 1983 President Ronald Reagan launched the Strategic Defense Initiative (SDI) to build space- and ground-based missile defense systems. The space-based component was abandoned as impractical, and the focus shifted to Ground-based Midcourse Defense systems (GMD). Despite disappointing results and program test failures, Congress and the George W. Bush administration pressed forward with spending billions on acquiring systems of questionable reliability. “We recognize the problems we have had with all the currently fielded interceptors,” Undersecretary of Defense Frank Kendall old an industry gathering in February 2014. “The root cause was a desire to field these things very quickly and very cheaply; we are seeing a lot of bad engineering, frankly, and it was because there was a rush.”

  • Inexpensive seismic alert device may help Mexico City residents

    Mexico City has been experiencing an unusually large number of tremors within the past few months, and though the country has one of the most advanced seismic alert systems in the world, many residents are unable to receive notifications before tremors occur. Mexican regulations limit the sale of government-issued earthquake alert receivers to one private company, but since the receivers cost an average of $310, most families are unable to afford them. Andres Meira, a 39-year-old architect, has designed an earthquake alert receiver, which costs only $54 at retail, which taps into the government’s earthquake alert frequency to notify its users of a pending earthquake.

  • The real reason for a decline in violent crime

    A scientific analysis of twenty million words recorded during 150 years of criminal trials at London’s Old Bailey reveals how changes in culture rather than law helped to reduce violent crime, according to a new study. “What we have been able demonstrate through analyzing the language used in court is that the decline in less serious forms of violence, such as assault, was not led by legislation or moments of dramatic change in the law, but by social attitudes,” says one of the authors.

  • Number of world’s nuclear weapons reduced, but modernization continues

    The overall number of nuclear weapons in the world continues to decline, but none of the nuclear weapon-possessing states are prepared to give up their nuclear arsenals for the foreseeable future. At the start of 2014 nine states — the United States, Russia, the United Kingdom, France, China, India, Pakistan, Israel, and North Korea — possessed approximately 4000 operational nuclear weapons. If all nuclear warheads are counted, these states together possessed a total of approximately 16,300 nuclear weapons compared to 17,270 in early 2013.
