• How Does USAMRIID Shut Down Impact Nation’s Bioterrorism Laboratory Response Network?

    The Laboratory Response Network (LRN) is a collaborative federal effort run by the U.S. Centers for Disease Control and Prevention in cooperation with other federal agency and public health partners. The U.S. Army Research Institute of Infectious Diseases (USAMRIID) Special Pathogens Laboratory at Fort Detrick is one of only three National Laboratories at the top of the protective umbrella of the LRN structure, along with those operated by the CDC and the Naval Medical Research Center (NMRC), responsible for specialized characterization of organisms, bioforensics, select agent activity, and handling highly infectious biological agents. It begs the question then, what happens when an important component of the nation’s biopreparedness infrastructure fails to meet CDC biosafety requirements and has its Federal Select Agent certification pulled?

  • Governments Failing to Understand Global Catastrophic Risks: Report

    Governments are failing to understand the human-driven catastrophic risks that threaten global security, prosperity and potential, and could in the worst case lead to mass harm and societal collapse, say researchers. The plausible global catastrophic risks include: tipping points in environmental systems due to climate change or mass biodiversity loss; malicious or accidentally harmful use of artificial intelligence; malicious use of, or unintended consequences, from advanced biotechnologies; a natural or engineered global pandemic; and intentional, miscalculated, accidental, or terrorist-related use of nuclear weapons.

  • Evaluate AI capabilities in Helping Paramedics

    Paramedics must make numerous life-saving decisions, often in the back of an ambulance with limited time. While they at times call doctors for additional medical directives, precious seconds tick away for the patient during these back-and-forth conversations. DHS S&T partnered with its Canadian counterpart to examine whether artificial intelligence could be used to improve that information overload.

  • Powerful Potential Weapon May Overcome Antibiotic Resistance

    UNC School of Medicine researchers led by Brian Conlon, PhD, discover how molecules called rhamnolipids could make common aminoglycoside antibiotics effective against the toughest Staph infections.

  • Russia's Nclear Propulsion Experiment a Cause for Worry

    An explosion last Tuesday at a Russian military test site caused a spike in radiation levels, forcing the evacuation of a small town. Experts say the incident occurred during the test of a new nuclear-powered cruise missile. Both superpowers experimented with nuclear propulsion of rockets during the cold war, but without success. Experts worry if a nuclear-powered cruise missile carries a conventional warhead to its target, an accident occurring with this missiles may turn what was meant to be a non-nuclear attack into a nuclear one, even if the explosion and radiation dispersion would be smaller relative to a “real” nuclear attack.

  • Italians Decided to Fight a Conspiracy Theory. Here's What Happened Next.

    Alongside the flat-earthers, 9/11 truthers and Obama birthers, the anti-vaccine conspiracy theorists have always had a special distinction: They can do immediate and specific damage in a way that the others can’t. Birtherism surely increased Americans’ distrust of politics, though in ways that are hard to pin down. By contrast, when anti-vaxxers persuade parents not to vaccinate children, the result can be sickness and even death.

  • Humanity’s Ability to Feed Itself Under Growing Threat

    A new UN report warns that the world’s land and water resources are being exploited at “unprecedented rates,” and that the combination of this increasingly more rapid exploitation with climate change is putting dire – and threatening — pressure on the ability of mankind to feed itself.

  • Yes, Flesh-Eating Bacteria Are in the Warm Coastal Waters – but it doesn’t mean you’ll get sick

    News reports about flesh-eating bacteria — V. vulnificus —tend to focus on people dying or losing limbs from the bacteria. It’s not front-page news when someone has a mild skin infection or eats a bad oyster and spends a couple days in the bathroom. We don’t often identify the most mild illnesses because people typically don’t seek medical care for them. Even so, V. vulnificus infections are rare. The Centers for Disease Control and Prevention estimates that about 205 infections occur each year, of which 124 were reported in 2014, including 21 deaths.

  • Nuclear Power Offers an Abundant Supply of Low-Carbon Energy. But What to Do With the Deadly Radioactive Waste?

    The dilemma of how to manage nuclear waste — radioactive materials routinely produced in large quantities at every stage of nuclear power production, from uranium mining and enrichment to reactor operation and the reprocessing of spent fuel — has taxed the industry, academics and governments for decades. Along with accidents, it has been a major reason for continuing public opposition to the industry’s further expansion despite substantial interest in nuclear power’s status as a low-carbon power source that can help mitigate climate change. The race is on to develop new strategies for permanently storing some of the most dangerous materials on the planet.

  • Bashar al-Assad’s Updated, Sinister Version of Biological Warfare

    Biological warfare is generally understood as the deliberate wartime introduction of a lethal pathogen with the intent to kill or maim. Syria under President Bashar al-Assad is pursuing a sinister variation—one with long and dangerous historical precedents. Assad’s government has allowed pathogens normally controlled by public health measures—such as clean water, sanitation, waste disposal, vaccination, and infection control—to emerge as biological weapons through the deliberate destruction and withholding of those measures. The conflict has in effect reversed public health advances to achieve levels of disease not seen since the Napoleonic era.

  • 460,000 Premature Deaths: The Horror That Was Nuclear Weapons Testing

    In March 1954, over the Bikini Atoll, the United States detonated a 15-megaton hydrogen bomb —one thousand times more powerful than the bomb that destroyed Hiroshima. It was the largest explosion ever set off by Americans, and also the dirtiest. Researchers have now found that, more than sixty years after the nuclear tests the United States conducted in the area, the levels of radiation in several Marshall Island atolls, exceed that found at Chernobyl or Fukushima. The United States also detonated hundreds of atomic bombs in Nevada, and a 2017 study suggested that fallout from the Nevada nuclear testing could have led to between 340,000 and 460,000 premature deaths, mostly Americans and mainly through cancer.

  • 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.

  • 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.

  • 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.

  • 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.
