An Argentinian prosecutor will assess the findings of a group of forensic analysts who discovered more evidence indicating that Argentinian prosecutor Alberto Nisman was murdered. Nisman, who investigated the ties between Iran and the July 1994 bombing of a Jewish community center in Buenos Aires, as well as a cover up by the previous Argentine government of Iran’s role in the attack, was found dead with a bullet wound to the head in January 2015. His death came hours before he was scheduled to appear before a closed session of the Argentinian Congress.

A new report paints a bleak picture of economic life under the Islamic State. The report’s authors estimate that the Islamic State contributed to a 23 percent reduction in the GDP of cities under its control, based on novel applications of satellite-derived data.

Racists and terrorists, and many other extremists, have used the internet for decades and adapted as technology evolved, shifting from text-only discussion forums to elaborate and interactive websites, custom-built secure messaging systems and even entire social media platforms. Recent efforts to deny these groups online platforms will not kick hate groups, nor hate speech, off the web. In fact, some scholars theorize that attempts to shut down hate speech online may cause a backlash, worsening the problem and making hate groups more attractive to marginalized and stigmatized people, groups, and movements. The tech industry, law enforcement, and policymakers must develop a more measured and coordinated approach to the removal of extremist and terrorist content online. The only way to really eliminate this kind of online content is to decrease the number of people who support it.

The National Academies of Sciences has examined policies and practices governing dual-use research in the life sciences – research that could potentially be misused to cause harm – and its findings identify multiple shortcomings. While the United States has a solid record in conducting biological research safely, the policies and regulations governing the dissemination of life sciences information that may pose biosecurity concerns are fragmented. Evidence also suggests that most life scientists have little awareness of biosecurity issues, the report says, stressing the importance of ongoing training for scientists.

Hezbollah leader Hassan Nasrallah said that the Syrian government has won the war in Syria. Speaking at a religious event, Nasrallah said that opponents of Syrian President Bashar al-Assad had failed and that now “the path of the other project has failed and wants to negotiate for some minor gains. We have won in the war [in Syria]”. He went on to say that “what remains are pockets of resistance.”

Sixteen years ago, on September 11, 2001, al-Qaida conducted the most destructive terrorist attack in history. An unprecedented onslaught from the United States followed. One-third of al-Qaida’s leadership was killed or captured in the following year. The group lost its safe haven in Afghanistan, including its extensive training infrastructure there. Its surviving members were on the run or in hiding. Though it took nearly ten years, the United States succeeded in killing al-Qaida’s founding leader, Osama bin Laden. Since 2014, al-Qaida has been overshadowed by its former ally al-Qaida in Iraq, now calling itself the Islamic State. In other words, al-Qaida should not have survived the sixteen years since 9/11. So why has it?

The Saudi embassy in Washington, D.C. paid two Saudis to conduct a “dry run” of the 9/11 attacks, documents submitted by lawyers for plaintiffs in a terrorism case against the Saudi government show. The complaint stated that the Saudi government paid two nationals, posing as students in the United States, to take a flight from Phoenix to Washington in November 1999 in order to test out flight deck security. The two Saudi nationals, whose tickets were paid for by the Saudi embassy, took a flight from Phoenix to Washington, but their persistent questions of the crew about cockpit security, and their several attempts to enter the cockpit, led the pilots to make an emergency landing in Ohio, and the two Saudis were escorted off the plane by FBI agents. The two men were released after an initial interrogation by the FBI.

When law enforcement officers and first responders arrive at an emergency involving radiation, they need a way to swiftly assess the situation to keep the public and environment safe. Having analysis tools that can quickly and reliably make sense of radiation data is of the essence. Sandia National Laboratories developed a tool called InterSpec, available for both mobile and traditional computing devices, can rapidly and accurately analyze gamma radiation data collected at the scene.

Regardless of the specifics of the Sunday test, one thing is clear: North Korea will achieve — within months, not years, and if it has not achieved this already – the capability to deliver a nuclear weapon to the continental United States and detonate it over a major American city. Does the United States have the means to protect itself against a North Korean nuclear attack?
