• Lab-Leak of Genetically Modified Virus: Lawmakers’ Report

    Rep. Michael McCaul (R-Texas) released on Monday a third installment in his investigation into the origins of the virus. The report says that the preponderance of evidence suggests that the pandemic outbreak stemmed from a genetically modified virus which leaked from Wuhan Institute of Virology.

  • Natural Origin or Genetic Manipulation? We “Can't Say for Sure Yet”: David Baltimore

    David Baltimore, president emeritus of Caltech and Distinguished Professor of Biology, is a virologist who received the Nobel Prize for his research into viral genetics. He says that “But the fact that evolution might have been able to generate SARS-CoV-2 doesn’t mean that that’s how it came about. I think we very much need to find out what was happening in the Wuhan Institute of Virology. I think that we can’t say for sure yet whether the SARS-CoV-2 virus came from natural origins or if it was genetically manipulated somehow.”

  • Water Systems Vulnerable to Cyberthreats

    In February, a hacker tried to manipulate the water utility’s computers in Oldsmar, Fla. so that the level of lye in the water would be raised. Joel Griffin writes that “had the perpetrator not been caught…. this cyber-attack could have resulted in actual physical harm to residents and potentially even deaths. The simplicity of this cyber-attack … also illustrates the gravity of the situation facing water utilities,” as they try to implement contemporary IT security solutions to decades-old equipment ad operational technology.

  • Lawmakers Looking to Curb Chinese Ownership of U.S. Farmland

    The Chinese threat to American food security, so far, would seem minimal: As of December 2019, Chinese agricultural real estate holdings in America totaled about 78,000 hectares, which is about 0.02 percent of America’s roughly 3.6 million square kilometers of total farmland. Still, U.S. lawmakers are seeking to restrict Chinese purchases of American farmland amid fears that such purchases could ultimately pose a threat to the U.S. food supply chain.

  • Building Resilience against Agroterrorism, Agro-crime Threats

    Agroterrorism and agro-crime constitute a considerable threat to the economy and public health. To effectively deal with agroterror or agro-crime using pathogens of animal origin, it is crucial that veterinary and law enforcement agencies are equipped to work together to jointly plan, prepare, and respond to animal disease outbreaks.

  • CDC: Delta as Contagious as Chickenpox

    In an internal document leaked to the Washington Post Friday, the CDC say the Delta variant (B1617.2) is as contagious as chickenpox. The agency also said that, although vaccinated people rarely get serious breakthrough infections, when they do get infected they can transmit the virus as easily as unvaccinated people.

  • China Used Vaccines, Trade to Get Ukraine to Drop Support for Xinjiang Scrutiny

    On 22 June, Ukraine signed a UN-sponsored document, along with more than 40 other countries, calling for China to allow independent observers immediate access to Xinjiang, where Beijing is operating a camp system that UN officials estimate has interned more than 1 million Uyghurs, Kazakhs, and other Muslim minorities. Two days later, Ukraine withdrew its signature after China threatened to limit trade with Ukraine and withhold Ukrainian access to COVID-19 vaccines.

  • New Book Helps Readers Spot Online Health Scams

    UBC’s Dr. Bernie Garrett, the author of a new book on health scams, misinformation, and disinformation, says that “Scam marketers are well-versed in modern advertising techniques and the psychology of persuasion. They know all the triggers that can help sell a product.” He adds that, during the COVID period, such scams “definitely have proliferated, and this has been aided by social media… Unfortunately, people can post misinformation on social media with no real consequences.”

  • Scientists Model “True Prevalence” of COVID-19 Throughout Pandemic

    Scientists have developed a statistical framework that incorporates key COVID-19 data — such as case counts and deaths due to COVID-19 — to model the true prevalence of this disease in the United States and individual states. Their approach projects that in the U.S. as many as 60 percent of COVID-19 cases went undetected as of 7 March 2021, the last date for which the dataset they employed is available.

  • U.K. COVID “Pingdemic” Sparks Labor Shortage

    More than 600,000 people have been pinged by the U.K.’s coronavirus warning app and told to self-isolate. Business leaders warn that the lack of available workers is putting the economic recovery at risk.

  • Protecting Lives on the Wildland Fire Line

    Unlike first responders who fight structural fires, wildland firefighters are unable to use the current standard respirator systems, which are heavy, limited to 45 minutes of air and are too bulky. Since the current standard equipment for respiratory protection is a bandanna, DHS S&T and partners designed the Wildfire Respirator around a lightweight mask covering just the mouth and nose, relying on filtration rather than on heavy tanks of compressed air.

  • Smartphone Screens Effective Sensors for Soil or Water Contamination

    The touchscreen technology used in billions of smartphones and tablets could also be used as a powerful sensor, without the need for any modifications.

  • Chinese Company’s Global Genetic Data Collection Poses Economic, Security Threats: Experts

    A Chinese gene company is collecting genetic data through prenatal tests from women in more than 50 countries— including Germany, Spain and Denmark, as well as in Britain, Canada, Australia, Thailand, India and Pakistan. Collecting the biggest and most diverse set of human genomes could propel China to dominate global pharmaceuticals, and also potentially lead to genetically enhanced soldiers, or engineered pathogens to target the U.S. population or food supply, biosecurity experts told Reuters.

  • Surgeon General Urges ‘Whole-of-Society’ Effort to Fight Health Misinformation

    “Misinformation is worse than an epidemic: It spreads at the speed of light throughout the globe, and can prove deadly when it reinforces misplaced personal bias against all trustworthy evidence,” said National Academy of Sciences President Marcia McNutt. “Research is helping us combat this ‘misinfodemic’ through understanding its origins and the aspects of human nature that make it so transmittable.”

  • 5 Million Deaths a Year Linked to Abnormal Temperatures

    More than five million extra deaths a year can be attributed to abnormal hot and cold temperatures, according to a new study.
