• Forensic Science Method for Firearm Identification Is Flawed

    Like fingerprints, a firearm’s discarded shell casings have unique markings. This allows forensic experts to compare casings from a crime scene with those from a suspect’s gun. Finding and reporting a mismatch can help free the innocent, just as a match can incriminate the guilty. But a new study reveals mismatches are more likely than matches to be reported as “inconclusive” in cartridge-case comparisons.

  • Report details Nazi Medical Crimes

    The Holocaust and other mass murders under the Nazi regime would hardly have been conceivable without the involvement of medical professionals. This has once again been highlighted by a commission of twenty international researchers who published a comprehensive report on Nazi medical crimes.

  • Iran Now Has Enough Enriched Uranium for “Several” Nuclear Bombs: IAEA

    In 2015, the world powers reached an agreement with Iran which severely restricted its nuclear weapons-related activities. In 2018, then-President Donald Trump unilaterally pulled the United States out of the accord without replacing it with any alternative mechanism to constrain Iran’s nuclear weapons-related activities. Trump’s decision allowed Iran to relaunch its nuclear weapons program, and the IAEA’s director-general has just warned that Tehran has enough enriched uranium for “several” nuclear bombs if it made the decision to build them.

  • Detecting Nuclear Materials Using Light

    Sandia materials scientist developed the state of the art technology known as Organic Glass Scintillators for radiation detection. Organic Glass Scintillators emit light in the presence of radiation.

  • More Asian Americans Are Buying Guns. Why?

    Asian Americans traditionally have the lowest rates of ownership than any other measured demographic in the US, but saw a 43% rise in ownership between 2019 and 2020, starting with the pandemic. A rise in racist attacks and crimes is diminishing Asian Americans’ trust in the US justice system.

  • Striving for a More Secure World

    PNNL experts work with international partners to tackle cross-border biological and chemical threats. PNNL’s border security focus can be traced to the breakup of the Soviet Union in the early 1990s. U.S. policy makers became concerned about the security of nuclear material in the newly independent states of the former U.S.S.R.

  • Is the Fear of Cyberwar Worse Than Cyberwar Itself?

    Unrealistic cyberwar expectations could hold the insurance industry back, and that’s the real economic security problem. The “hyperbolic characterization of cyberwar is likely a bigger problem than the threat of cyberwar itself. The problem is one of economic security,” Tom Johansmeyer writes.

  • Mass Shootings Often Put a Spotlight on Mental Illness, but Figuring Out Which Conditions Should Keep Someone from Having a Gun Is Not Easy

    Mental illness again became a central theme after the mass shooting in Maine on Oct. 25, 2023, in which records suggest that the shooter had a history of serious mental health issues. The relationship between mental illness and guns, and risk mitigation, is complicated, and the majority of people with mental illness do not seek treatment.

  • Minnesotans Will Soon Be Able to Disarm Dangerous People. Will it Save Lives?

    Lawmakers and advocates say the efficacy of the state’s new red flag law, set to take effect in 2024, will depend on implementation and enforcement. Minnesota and Michigan are the latest of 21 states to enact Extreme Risk Protection Order laws.

  • Fire-Tested Systems Help Crews Survive Truck Burn-Overs

    Terrifying moments when flames can overrun and burn over a fire truck are called flashover or burn-over. While firefighters have strategies and operational procedures to minimize risk, these dangerous events still occur and can be fatal. Water spray systems are protecting fire trucks and firefighters from burn-overs.

  • New survey: 70% of Americans Agree Jew-Hatred Is a Serious and Growing Problem in the U.S.

    In the month following Hamas’s terror attack on Israel, antisemitic incidents in the U.S. increased by 316 percent compared to the same time period last year. At the same time, Americans are growing increasingly concerned about antisemitism, with more than 70 percent agreeing in a new survey that Jew-hatred is a serious problem.

  • Worrying Trends Highlight Need for Vigilance Against Homegrown Terrorism

    Despite intense efforts to counter violent extremism over the past two decades, the threat of domestic terrorism still endangers Australians. The focus has shifted from primarily transnational jihadists to violent homegrown ideologues with a range of motivations. As violent extremism evolves, Australia must adapt its strategy to confront this persistent challenge and protect social cohesion and national security.

  • The Chinese Military’s Skyrocketing Influence in Space

    China has already begun leading the world in military satellite launches, sending 45 defense-related satellites into orbit in 2022. That was 15 more than the US sent into orbit. While the People’s Liberation Army’s space plans are not reliably disclosed to the public, its actions make it clear that China has found its way to space, and it plans to stay.

  • What Jan. 6 Revealed About QAnon and Militias

    Beginning 3-4 years ago, the Oath Keepers, Proud Boys, and Three Percenters — the three extremist anti-government militia groups playing a prominent role in the 6 January attack on the Capitol — have adjusted their ideological perspective to find a rallying point around QAnon conspiracy theories. “Throughout 2020, as members of extremist groups coalesced in what researchers have termed a ‘militia-sphere,’ their messaging latched on to QAnon conspiracy theories.”

  • Civilian Deaths and Proportionality in the Israel–Hamas War

    Hamas invites civilian casualties by its positioning of military assets, and now that it knows that Israel’s risk tolerance is well beyond anything it has seen before, it likely sees outcries over more civilian casualties leading to a ceasefire as its only chance of survival. And Washington hopes that Israel can inflict grievous damage on Hamas before the White House will have to acquiesce to public opinion and back some kind of ceasefire. Israel, Hamas and Washington are all accepting of civilian casualties in Gaza—they only differ in how many and why.
