  • California's Wildfire Season Has Lengthened, and Its Peak Is Now Earlier in the Year

    California’s wildfire problem, fueled by a concurrence of climate change and a heightened risk of human-caused ignitions in once uninhabited areas, has been getting worse with each passing year of the 21st century.Researchers have found that the annual burn season has lengthened in the past two decades and that the yearly peak has shifted from August to July.

  • Syrian Missile Explodes Near Israel’s Dimona Nuclear Reactor

    A Syrian missile landed and exploded about forty miles from Israel’s nuclear reactor in Dimona. The IDF described the incident as unintentional: A Russia-made SA-5 was launched by a Syrian air defense unit, aiming at an IDF aircraft attacking Syrian military targets near Damascus. It appears that the Syrian missile had missed its target, and continued its flight trajectory which carried it all the way to the Negev desert, about 300 kilometers south of Damascus. There is unease in Israel over the fact that the missile managed to evade Israel’s robust anti-missile defenses.

  • Mathematics Professor and University Researcher Indicted for Grant Fraud

    A federal grand jury in Carbondale, Ill. On Wednesday returned an indictment charging a mathematics professor and researcher at Southern Illinois University – Carbondale (SIUC) with two counts of wire fraud and one count of making a false statement. The prosecution is part of the Justice Department’s ongoing China Initiative.

  • “I Felt Hate More Than Anything”: How an Active Duty Airman Tried to Start a Civil War

    Steven Carrillo, a 32-year-old Air Force sergeant, wanted to incite a second Civil War in the United States by killing police officers he viewed as enforcers of a corrupt and tyrannical political order — officers he described as “domestic enemies” of the Constitution he professed to revere. Carrillo’s path to the Boogaloo Bois shows the extremist anti-government group is far more organized and dangerous than previously known.

  • Iran Says 60 Percent Enrichment “Under Way” at Natanz Site

    Iranian officials say the country has begun enriching uranium up to 60 percent purity, higher than it has ever done before, despite ongoing talks between Tehran and world powers to revive the 2015 nuclear deal. Under the 2015 nuclear deal, Iran had committed to keep enrichment to 3.67 percent. Recently it has been enriching up to 20 percent, saying the deal was no longer enforceable. Enriching uranium to 60 percent would be the highest level achieved by Iran’s nuclear program, it is still short of the 90 percent purity needed for military use.

  • UN Watchdog Confirms Assad Used Chemical Weapons against Civilians

IIT concludes that units of the Syrian Arab Air Force used chemical weapons in Saraqib on 4 February 2018.Since 2011, the year the civil war in Syria began, the Assad regime has launched atleast 336 chemical attacks, using Sarin and chlorine, against Sunni civilians.

  • In a Year of Racial and Political Turmoil, This Black Gun Group Is Booming

    The National African American Gun Association was founded as a refuge from the discrimination and fear that often come with being Black and armed in America. Thousands of new members have joined its ranks in 2020.

  • Strengthening Nuclear Storage Research

    Today, nuclear power utilities store over 80,000 metric tons of spent nuclear fuel across the nation. Since the fuel will remain in dry storage longer than was expected, scientists are working to better understand exactly how the fuel behaves under extended storage conditions, how the canisters age, and the forces the two would undergo when shipped and stored for long periods.

  • Combining News Media and AI to Rapidly Identify Flooded Buildings

    Artificial intelligence (AI) has sped up the process of detecting flooded buildings immediately after a large-scale flood, allowing emergency personnel to direct their efforts efficiently. Now, researchers have created a machine learning (ML) model that uses news media photos to identify flooded buildings accurately within 24 hours of the disaster.

  • Improving Vehicle Inspections at Security Checkpoints

    Federal agencies screen an average of 235,000 vehicles every day for illegal contraband, explosives and other potential threats in the United States. Currently, federal law enforcement personnel (LEP) perform a visual search of the undercarriage using mirrors, or, if available, an under-vehicle inspection scanner. The scanning units are expensive, have moderate resolution and require vehicles to go only five miles per hour. DHS S&T is changing that.

  • Epidemic of Firearm Injury Spurs New Wave of Research

    Fifty-five years ago, America’s death toll from automobile crashes was sky-high. Nearly 50,000 people died every year from motor vehicle crashes, at a time when the nation’s population was much smaller than today. But with help from data generated by legions of researchers, the country’s policymakers and industry made changes that brought the number killed and injured down dramatically. Experts welcome new federal funding for more injury prevention research to reduce the toll of a leading cause of death while respecting Second Amendment rights.

  • Natanz Attack Sets Back Iran’s Nuclear Operations

    The Israeli Sunday sabotage operation against Iran’s nuclear facility at Natanz destroyed a well-protected electrical substation housed 40 to 50 meters underground.Iranian officials said that thedestruction of the power supply led to the damage or destruction of “thousands of centrifuges” by causing them to slow down too rapidly.

  • Sabotage May Weaken Tehran’s Position in Indirect Talks with U.S.

    With the U.S. and Iran planning their second round of indirect nuclear talks in Vienna this week, some analysts say Sunday’s sabotage of Iran’s Natanz nuclear site has weakened the Iranian position, while others contend it all depends on Iran’s response.

  • The Natanz Blackout: Can the Iran Deal Talks Still Succeed?

    Washington and Tehran seem determined to revive the deal that freezes Iran’s nuclear program, despite domestic criticism on both sides and the apparent sabotage of an Iranian facility.
