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

    By Sam Telford

    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.

  • American Nurses Not Prepared for a Catastrophe: Study

    On average, American colleges and universities with nursing programs offer about one hour of instruction in handling catastrophic situations such as nuclear events, pandemics, or water contamination crises, according to two recent studies. “We are putting people out there to attend these emergencies, and we owe it to them to prepare them right,” says one expert.

  • The Challenge: Feeding 11 billion People Without Spread Infectious Disease

    Within the next 80 years, the world’s population is expected to top 11 billion, creating a rise in global food demand — and presenting an unavoidable challenge to food production and distribution. But a new study describes how the increase in population and the need to feed everyone will also, ultimately, give rise to human infectious disease, a situation the authors of the paper consider “two of the most formidable ecological and public health challenges of the 21st century.

     

  • Dangerous Heat Wave Is Building in the Central and Eastern U.S.

    The National Weather Service said Thursday that an upper-level ridge is building over the southeastern U.S., setting the stage for what will be a miserably hot and humid weekend for millions of Americans. Heat advisories and warnings affect 154 million Americans. In many major population centers, the heat index  is forecast to peak around 110 degrees between Friday and Sunday.

  • These Hackers Made an App That Kills to Prove a Point

    Two years ago, researchers Billy Rios and Jonathan Butts discovered disturbing vulnerabilities in Medtronic’s popular MiniMed and MiniMed Paradigm insulin pump lines. An attacker could remotely target these pumps to withhold insulin from patients, or to trigger a potentially lethal overdose. And yet months of negotiations with Medtronic and regulators to implement a fix proved fruitless. So the researchers resorted to drastic measures. They built an Android app that could use the flaws to kill people.

  • WHO Declares Ebola Outbreak in Congo an Emergency of “International Concern”

    The UN’s World Health Organization (WHO) on Wednesday declared the Ebola outbreak in the Democratic Republic of Congo a “public health emergency of international concern.” “It is a measure that recognizes the possible increased national and regional risks and the need for intensified and coordinated action to manage them,” said the WHO in a statement.

  • German law would require measles vaccination to attend schools, kindergartens, daycare

    German children will have to prove they have had a measles vaccination before they would be allowed to attend kindergarten or go to school. A new draft law imposes steep fines on parents who refuse to immunize their children.

  • Bill Expands Compensation for Victims of Radiation Exposure

    Tens of thousands of individuals, including miners, transporters, and other employees who worked directly in uranium mines, along with communities located near test sites for nuclear weapons, were exposed during the mid-1900s to dangerous radiation that has left communities struggling from cancer, birth defects, and other illnesses.

  • Fighting anthrax by removing the bacterium’s armor

    Anthrax is a deadly and highly resilient disease, caused by the spore-forming bacterium Bacillus anthracis. Historically, it was a major cause of death in humans and cattle. has shown that removing the armor of the bacterium that causes anthrax slows its growth and negatively affects its ability to cause disease.

  • Radiation in Parts of the Marshall Islands Is Far Higher than Chernobyl, Study Says

    Think of the most radioactive landscapes on the planet and the names Chernobyl and Fukushima may come to mind. Yet research published Monday suggests that parts of the Marshall Islands in the central Pacific, where the United States conducted 67 nuclear tests during the Cold War, should be added to the list.

  • Southwest to Endure 50 Days or More a Year When Temperature “Feels Like” Exceeding 105 Degrees

    Increases in potentially lethal heat driven by climate change will affect every state in the contiguous U.S. in the decades ahead. Few places would be unaffected by extreme heat conditions by midcentury and only a few mountainous regions would remain extreme heat refuges by the century’s end. The dangerously soaring heat across the U.S. is posing unprecedented health risks.

  • What the Measles Epidemic Really Says about America

    The critic Susan Sontag observed that disease can serve as a metaphor—a reflection of the society through which it travels. Now, a virus is offering insights into the country’s psychic and civic condition. Two decades ago, measles was declared eliminated in the U.S. Yet in the first five months of this year, the Centers for Disease Control and Prevention recorded 1,000 cases—more than occurred from 2000 to 2010. Three cultural conditions have contributed to the resurgence of measles in the United States. One is historical forgetting: contemporary America suffers from a dangerous lack of historical memory. The second is diminished trust in government. As distrust of government has grown, so too has distrust of vaccines. The third is a population that suffers from overconfidence in its own amateur knowledge. This third condition is especially dangerous: It’s one thing to Google a food to see whether it’s healthy. It’s quite another to dismiss decades of studies on the benefits of vaccines because you’ve watched a couple of YouTube videos.
