• Active shooters caused nearly 750 casualties in 2017

    More Americans were killed or wounded by active shooters in 2017 than in any year since the Federal Bureau of Investigation began keeping track. All told, nearly 750 people were shot in 30 incidents, according to a newly released FBI report. The shooters were of different ages, from different places, and motivated by different grievances. But all were men, and all acted alone.

  • Mountain collapsed in North Korea after most recent nuclear test

    As North Korea’s president pledges to “denuclearize” the Korean peninsula, scientists published the most detailed view yet of the site of the country’s latest and largest underground nuclear test on 3 September 2017. The new picture of how the explosion altered the mountain above the detonation highlights the importance of using satellite radar imaging, called SAR (synthetic aperture radar), in addition to seismic recordings to more precisely monitor the location and yield of nuclear tests in North Korea and around the world.

  • Earthquake science could have predicted North Korea’s nuclear climbdown

    Just days after North Korea announced it was suspending its testing program, scientists revealed that the country’s underground nuclear test site had partially collapsed. The collapse may have played a role in North Korea’s change in policy. If correct, and with the hindsight of this research, we might have speculated that the North Koreans would want to make such an offer of peace. This shows how scientific analysis normally reserved for studying natural earthquakes can be a powerful tool in deciphering political decisions and predicting future policy across the globe.

  • The past as prologue? Iran’s nuclear weapons project

    In a major coup, Israel’s intelligence operatives smuggled tens of thousands of documents from Iran’s nuclear weapons archive – the existence of which Iran had denied – which show the methodical steps Iran took between 199 and 2003 to build nuclear weapons. Two nuclear weapons experts say that the very existence of the archive is proof that Iran not only lied about its past nuclear weapons plans, but also about its future plans.

  • 3D printing of weapons: A threat to global, national, and personal security

    Additive manufacturing – also known as 3D printing — could benefit military adversaries, violent extremists and even street criminals, who could produce their own weapons for use and sale. As this technology further develops, and without proper controls, violent actors might be able to replicate more sophisticated weapons systems, print lethal drones, and even produce jamming devices or cheap decoys that disrupt intelligence collection.

  • Countering drones in urban environments

    New technology can provide advances in the way we do things, expanding areas previously left unexplored and simplifying previously burdensome tasks. This is true with advancements in Unmanned Aerial Systems (UAS), or drones. Given their rapid technology advancement and proliferation, the public safety and homeland security communities must address the fact that drones can be used nefariously or maliciously to hurt people, disrupt activities and damage infrastructure.

  • Twitter users likely to spread falsehoods during disasters

    We know that Twitter is littered with misinformation. But how good are the social media platform’s most active users at detecting these falsehoods, especially during public emergencies? Not good, according to researchers who examined more than 20,000 tweets during Hurricane Sandy and the Boston Marathon bombing.

  • Israel-Iran clashes: Latest updates

    Iranian forces in Syria did not ask the Syrian government for permission, or even notify Syrian leaders, before launching twenty missiles at Israel. Fox News said it had learn from European sources that, “The Iranian major general in charge of the Al-Quds Force in Syria, Qassem Soleimani, launched last night’s attack against Israel without the knowledge or the consent of the Assad regime.” Moreover, Iran launched the twenty missiles at Israel after being warned by Russia not to do so.

  • Israel destroyed “nearly all” of Iran’s military infrastructure in Syria

    On Wednesday night, in the largest Israeli air campaign against Syria since the 1973 war, and the largest-ever direct clash between the Iranian and Israeli militaries, Israel launched 70 missiles – 60 air-to-ground missiles fired from 28 F-15 and F-16 flying over Syria and Lebanon, and 10 surface-to-surface missiles launched from inside Israel — at key Iranian military targets all across Syria. Israel’s Defense Minister Avigdor Liberman said that the Israel had destroyed “nearly all” of Iran’s military infrastructure sites in Syria.

  • Assessing the Iran deal pullout

    Calling it a “great embarrassment” that fails to “halt Iran’s nuclear ambitions,” President Trump said Tuesday that he will pull out of the Joint Comprehensive Plan of Action (JCPOA), the Iran nuclear agreement that the previous administration negotiated to halt that nation’s progress toward atomic weapons. The national security, nuclear, and regional experts at Harvard Kennedy School’s Belfer Center for Science and International Affairs, who have been assessing the Iran nuclear situation for years, examined the president’s remarks and weighed in on the significance of Washington’s policy change and on what is likely to follow it.

  • Israeli rocket experience shows bomb shelters matter as much as interceptors

    The conflict between Israel and Iran emerged from the shadows early Thursday morning. Israel is worried about Iran’s deployment of missiles in Syria – and about Hezbollah’s 100,000 to 150,000 rockets. Other countries face rocket and missile threats too. It’s not surprising then that missile interceptors are in fashion. Israel credited its Iron Dome system with intercepting four rockets on Thursday. Civil defenses like warning sirens and bomb shelters receive less press coverage. Spectacular interceptor launches are more photogenic than concrete block houses. But Israel’s own experience shows civil defenses deserve at least as much attention as interceptors.

  • Shareholders force U.S. biggest gunmaker to report on the risks of gun violence

    Shareholders on Wednesday voted to require firearms manufacturer Sturm Ruger to complete a report on the reputational and financial risks posed to the company by gun violence. Sturm Ruger, which makes more guns annually than any other American company, must produce an assessment by February 2019. To create the report, the company will monitor incidents of violence involving its products and examine efforts to research and manufacture safer firearms.

  • As U.S. withdraws from Iran nuclear deal, experts consider fallout

    U.S. President Donald Trump’s decision to withdraw from the 2015 Iranian nuclear agreement reverberated throughout the Middle East, Europe, and elsewhere – all the more so because did not say what comes next in U.S. policy toward Iran, leaving a list of questions that experts are rushing to predict: Will Washington seek new negotiations with Tehran? Will Iran resume enriching uranium? Will Israel step up attacks on Iran’s proxies, such as Hezbollah in Lebanon, or militias in Syria? Will the U.S. European allies try to coax the Trump administration back to the negotiating table with Tehran? Will U.S. forces in Syria become more of a target for Iranian fighters?

  • Presidents often reverse U.S. foreign policy — how Trump handles setbacks is what matters most now

    President Trump’s decision to withdraw from the Iran nuclear deal is hardly Trump’s first foreign policy turnaround. But is Trump really such an outlier? As a scholar of American foreign policy, I know that many American presidents have reoriented international relations. Some of those policies succeeded. Many faced opposition. Ultimately, though, my research shows that what matters more to U.S. national security is how those presidents responded when their foreign policy shifts failed.

  • Improving fingerprinting technology

    Fingerprint capture technology has advanced to the point where high-quality rolled prints soon might be obtained without the manual assistance of a trained device operator. These advancements could help law enforcement collect information-rich prints more rapidly and economically.
