• No, Lyme Disease Is Not an Escaped Military Bioweapon, Despite What Conspiracy Theorists Say

    Could Lyme disease in the U.S. be the result of an accidental release from a secret bioweapons experiment? Could the military have specifically engineered the Lyme disease bacterium to be more insidious and destructive – and then let it somehow escape the lab and spread in nature? Is this why 300,000 Americans are diagnosed annually with this potentially debilitating disease? It’s an old conspiracy theory currently enjoying a resurgence with lots of sensational headlines and tweets. Even Congress has ordered that the Pentagon must reveal whether it weaponized ticks. And it’s not true.

  • What Dragonflies Can Teach Us about Missile Defense

    Dragonfly brains might be wired to be extremely efficient at calculating complex trajectories: Dragonflies catch 95 percent of their prey, crowning them one of the top predators int he world. Sandia Lab scientists are is examining whether dragonfly-inspired computing could improve missile defense systems, which have the similar task of intercepting an object in flight, by making on-board computers smaller without sacrificing speed or accuracy.

  • Missile Strike False Alarm Most Stressful for Less Anxious Hawaiians: Study

    After learning that a warning of a missile headed to Hawaii was a false alarm, the most anxious local Twitter users calmed down more quickly than less anxious users, according to a study of tweets before, during and after the event. “Can a false alarm of an impending disaster itself be a form of trauma? Our results suggest that the experience may have a lingering impact on some individuals well after the threat is dispelled,” says an expert.

  • Keeping First Responders Safe

    When two powerful earthquakes rocked southern California earlier this month, officials’ attention focused, understandably, on safety. How many people were injured? Were buildings up to code? How good are we at predicting earthquakes? Not a lot of people were thinking about urine, blood, and spit. But those substances are key to a PNNL effort to learn more about the health and safety of first responders.

  • Machine-learning Competition Improves Earthquake Prediction Capabilities

    Current scientific studies related to earthquake forecasting focus on three key points: when the event will occur, where it will occur, and how large it will be. The Kaggle competition, hosted by Los Alamos National Laboratory, provided a challenging dataset that was based on previously published laboratory analysis, to give the competitors a taxing project to explore. Competitors’ success predicting quake timing in the online Kaggle competition could help save lives, infrastructure.

  • Epigenetic Tool for Detecting Exposure to WMD

    With a $38.8 million award from DARPA, researchers are working on developing a field-deployable, point-of-care device that will determine in 30 minutes or less whether a person has been exposed to weapons of mass destruction or their precursors. The device will be capable of detecting the health effects of a number of substances associated with weapons of mass destruction, including biological agents, radiation, chemicals and explosives. The detection devices will scan potential exposure victims for epigenetic changes, that is, chemical modifications that affect genes, altering their expression while leaving the genetic code intact.

  • FBI Director: China No. 1 Counter-Intelligence Threat to the U.S.

    The FBI has more than 1,000 investigations of U.S. intellectual property theft in all 50 states with nearly all leading back to China, FBI Director Christopher Wray said, calling China the No. 1 counter-intelligence threat to the United States. Wray described the threat as “more deep, more diverse, more vexing, more challenging, more comprehensive and more concerning than any counter-intelligence threat that I can think of.”

  • 40 U.S. Diplomats in Cuba Have Suffered Brain Damage: Medical Report

    Brain imaging of 40 U.S. government personnel who served at the U.S. embassy in Havana in 2016, and who experienced a host of neurological symptoms after possible exposure of an unknown source, revealed significant differences in brain tissue and connectivity when compared to healthy individuals, according to a new report. Images reveal key brain differences, particularly in the cerebellum, between impacted patients and healthy individuals, which may underlie clinical findings previously reported by brain experts.

  • Cities Ban Government Use of Facial Recognition

    Oakland, Calif., last week became the third city in America to ban the use of facial recognition technology in local government, following prohibitions enacted earlier this year in San Francisco and Somerville, Mass. Berkeley, Calif., is also weighing a ban. The technology is often inaccurate, especially when identifying people who aren’t white men.

  • New Chip Device Identifies Miniscule Blood Residues for Forensic Applications

    Criminologists use luminol to identify microscopic blood drops, as well as low hydrogen peroxide concentrations, proteins and DNA. These are all invisible to the naked eye but become visible through a chemical reaction known as “chemiluminescence.” Detecting biological residues using this method is cost effective and advantageous since the detected signal does not depend on an external light source.

     

  • The U.S. Is Unprepared to Mobilize for Great Power Conflict

    The “fully mobilized Joint Force,” the National Defense Strategy tells us, will be capable of “defeating aggression by a major power; deterring opportunistic aggression elsewhere; and disrupting imminent terrorist and WMD threats.” Yet neither that document, nor U.S. planners in general, are sufficiently grappling with certain mobilization challenges that could prove decisive in a future great power conflict. The attacks of an adversary against U.S. critical infrastructure could cause major damage and disruption in ways that could undermine overall morale and create major impediments to mobilization. Given these threats and these apparent vulnerabilities, the resilience and survivability of the U.S. homeland must remain a core priority. So too, the U.S. military, which has become accustomed to operating in much more permissive environments in its recent history, must also be prepared to mobilize and operate under such demanding conditions.

  • China Cyber Attacks on AFSPC Contractors ‘Stealing Us Blind’

    “Cyber keeps me up at night,” says Brig. Gen. DeAnna Burt, director of Air Force Space Command (AFSPC) operations and communications, because China’s cyber warriors are routinely breaching defense and space contractor networks and stealing data on a regular basis. “For every defense contractor in this room, the thing that keeps me up at night is how we manage data on your systems or your sub’s systems,” she warned. “We have had breaches … the Chinese and others stealing things from cleared defense contractors.”

  • A New Red Scare Is Reshaping Washington

    The Committee on the Present Danger, a long-defunct group that campaigned against the dangers of the Soviet Union in the 1970s and 1980s, has recently been revived with the help of Stephen K. Bannon, the president’s former chief strategist, to warn against the dangers of China. “These are two systems that are incompatible,” says Bannon. “One side is going to win, and one side is going to lose.”

  • Q&A: How Ridgecrest Earthquakes Helped Scientists with ShakeAlert

    U.S. Geological Survey geophysicist Sarah Minson was in the thick of efforts to develop an earthquake warning system in California when a series of major temblors struck the sparsely populated community of Ridgecrest in the Mojave Desert this summer. The largest, a magnitude 7.1 quake on July 5, was the biggest to hit the state in decades. The Mercury News asked her about her work — and how this month’s big quakes is helping scientists refine California’s fledgling earthquake alert system.

  • Assessing Handheld Explosives Trace Detectors

    Individuals who carry explosives or have been involved in bomb making are likely to be contaminated with trace explosives, microscopic particles invisible to the naked eye. Without the right equipment, detecting trace explosives can be challenging for responders and security personnel. Handheld explosives trace detectors (ETDs) can be used to complement bomb-sniffing canines, which are still the gold standard in trace explosives detection. These detectors can be used to find trace explosives on individuals, hopefully preventing a dangerous incident.
