• Drones could save lives in disaster zones

    Research from the University of South Australia has shown for the first time that drones can be used to detect human vital signs in war zones and natural disasters. The researchers have successfully trialed unmanned aerial vehicles to measure heart and respiratory rates using remote-sensing imaging systems, while hovering three meters from humans.

  • Vietnam War: Who was right about what went wrong – and why it matters in Afghanistan

    The ghosts of the Vietnam War no doubt hovered over a recently assembled conclave of President Donald Trump’s advisers as they deliberated over the deteriorating situation in Afghanistan. In the Vietnam era, as today, the United States found itself engulfed in a seemingly never-ending war with mounting costs, unclear goals, and few signs of success. In both Vietnam and Afghanistan, successive presidents faced much the same options: Withdraw, decisively escalate, or do just enough to avoid losing. Like his predecessors in both wars, Trump chose the middle path – incremental escalation with no clear exit plan (what Daniel Ellsberg, in reference to the Vietnam War, called the “stalemate machine”). How can we to explain the seeming preference of U.S. presidents for muddling through – whether in Afghanistan or, fifty years ago, in Vietnam? It may be that the logic of the stalemate machine is built into the very concept of limited war. Or that it is a predictable consequence of how presidents manage the constraints posed by American politics. In any case, the histories of U.S. military involvements in Vietnam and Afghanistan should serve as warnings to future presidents who might be tempted to again jump onto the treadmill of perpetual war.

  • Big Power should cooperate to slow proliferation of hypersonic missiles

    Experts propose that despite their differences, Russia, China, and the United States should act jointly to head off a little-recognized security threat — the proliferation of hypersonic missiles beyond the three nations. the spread of this new class of weapons would increase the chance of strategic (missile-based) wars and would jeopardize nations small and large—including the three nations that now have the technology

  • Will North Korea sell its nuclear technology?

    Earlier this month CIA Director Mike Pompeo suggested “the North Koreans have a long history of being proliferators and sharing their knowledge, their technology, their capacities around the world.” My research has shown that North Korea is more than willing to breach sanctions to earn cash. Over the years North Korea has earned millions of dollars from the export of arms and missiles, and its involvement in other illicit activities such as smuggling drugs, endangered wildlife products and counterfeit goods. Still, there are only a handful of cases that suggest these illicit networks have been turned to export nuclear technology or materials to other states.

  • Breaking nuclear deal could bring hacking onslaught from Iran

    If the Trump administration discarded the nuclear deal with Iran, Tehran could retaliate quickly – and inflict considerable damage – by unleashing its increasingly aggressive Iranian hacker army. Cyber-experts who track Tehran’s hackers warn that the attacks might target U.S. power plants, hospitals, airports, and other components of the country’s critical infrastructure. Iran’s current hacking against Western targets is limited almost entirely to commercial espionage and dissident surveillance, but Teheran could quickly redirect its efforts in the event of a rupture of the nuclear pact.

  • The Madman Theory of North Korea

    By the fall of 1969, President Richard Nixon had become increasingly frustrated with the refusal of North Vietnam to engage in meaningful negotiations with the United States. He believed that the Soviet Union was the only country able to persuade the North Vietnamese leadership to be forthcoming – but how do you get the Kremlin to apply pressure on North Vietnam? Nixon’s idea: To convince Leonid Brezhnev that Nixon was a madman, capable of irrational action. Has President Donald Trump revived the Madman Theory in order to deal with North Korea’s nukes?

  • Israel shot down Iranian-supplied Hezbollah drone in border area

    Israel has shot down what an Iranian-supplied Hezbollah drone as it was about to cross the Syrian border into Israel. Analysts note that Hezbollah launched the drone only hours before Prime Minister Benjamin Netanyahu is to address the UN General Assembly. In his speech he is expected to highlight the destabilizing consequences of Iran’s growing influence in the Middle East. “We have seen a significant recent rise in [Hezbollah’s] drone capability,” an Israeli military source said.

  • DHS funds national consortium to develop better methods for fighting criminal activity

    The University of Arkansas at Little Rock has been named a priority partner in a new DHS-funded national consortium. SHS S&T S&T) will award the consortium a $3.85 million grant for its first operating year in a 10-year grant period to create the Center of Excellence for Criminal Investigations and Network Analysis (CINA). The center’s research will focus on criminal network analysis, dynamic patterns of criminal activity, forensics, and criminal investigative processes.

  • No internet? No problem: Improving communications during natural disasters

    Storms like Hurricane Irma and other natural disasters bring with them lots of uncertainty: where will they go, how much damage will they cause. What is certain is that no matter where they strike, natural disasters knock out power. And no power means no internet for thousands of people in affected areas. Researchers are proposing a new way of gathering and sharing information during natural disasters that does not rely on the internet.

  • No, we cannot shoot down North Korea’s missiles

    The number one reason we don’t shoot down North Korea’s missiles is that we cannot. The latest North Korean missile to fly over Japan did so at 475 miles over Japan at the apogee of its flight path. Neither Japan nor the United States could have intercepted the missile. None of the U.S. theater ballistic missile defense weapons in existence can reach that high. It is hundreds of kilometers too high for the Aegis interceptors deployed on Navy ships off Japan. Even higher for the THAAD systems in South Korea and Guam. Way too high for the Patriot systems in Japan, which engage largely within the atmosphere.

  • Storm surge prediction tool helps emergency managers

    When severe, life threatening weather systems bear down on residents and communities, emergency managers needed every tool available to make informed decisions regarding evacuations, emergency services, and resource staging. Back in June, as Tropical Storm Cindy was nearing the Texas and Louisiana coastlines, Texas state agencies – including the Texas Department of Transportation (TXDOT), which operates the ferries along the Texas Gulf Coast — were using a combination of online tools and observations to closely monitor water heights since ferries, a key aspect of the state evacuation plan, can’t operate if the water rises more than four and a half feet. Unfortunately, based on their observations, it looked like they were going to have to close the ferry down.

  • S&T, the Pentagon changing K-9 bomb detection

    DHS S&T Detection Canine Program partnered with the Pentagon Force Protection Agency (PFPA) to assist in developing a training initiative to add person-borne improvised explosive device (PBIED) detection capabilities to their canine teams. Traditionally, dogs sniff out “left-behind” bombs, but Sunny and the other members of his K-9 unit are also trained to pick up explosive scents on a person or any moving target.

  • Big data amplify existing police surveillance practices: Study

    The big data landscape is changing quickly, and researchers wonder whether our political and social systems and regulations can keep up. With access to more personal data than ever before, police have the power to solve crimes more quickly, but in practice, the influx of information tends to amplify existing practices.

  • Escaping an unwelcome visit from mother nature

    Hurricane Irma forced mandatory evacuations throughout the Florida Keys. But with only two main north-south roads in and out of Florida - interstates 95 and 75 - Irma quickly became an exercise in preparedness for a storm described at times as “the size of the state of Ohio.” “Evacuation may not be the best goal in all cases. An alternative strategy to evacuating people to a far away destinations is to build more hurricane shelters near population centers,” says one expert.

  • World unprepared to deal with the effects of a thermonuclear attack

    The world is not prepared to deal with the devastating effects of a thermonuclear attack, says an University of Georgia’s Cham Dallas. He said that the development of a hydrogen bomb by North Korea is a transformative event, especially from the point of view of the medical and public health response to a thermonuclear detonation.
