• 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.

  • Sen. Rubio Urges Senate to Pass Genomics Data Security Act

    Senator Marco Rubio urged the Senate to pass his Genomics Data Security Act following a new Office of Inspector General’s (OIG) report, which found that the Centers for Medicare and Medicaid Services (CMS) did not consider national security risks for any CMS programs. Rubio noted that Chinese and Russian labs may be receiving federal dollars to processing Americans’ genomic data.

  • Creating More Resilient Supply Chains Through Nature-Inspired Design

    Supply chains work a lot like food webs in natural ecosystems, in which biodiversity allows for adaptation during disruptions. The analogy turned out to be relevant particularly in looking at “black swan” events, which are unpredictable and hard to protect against—and for which adaptation, not prevention, is the main defense.

  • Why We Need to Talk Openly about Vaccine Side Effects

    How can health authorities and politicians help ensure public acceptance of vaccines which, their rare side effects aside, have proven effective in preventing serious Covid-19 disease? The best way to do this is to talk openly about all aspects of the vaccines, including potential negative aspects such as side effects.
