Kulkarni, Harvey) The need to understand the drivers of global vaccine hesitancy is perhaps more crucial than ever as the world gears up to introduce COVID-19 vaccines. Recent outbreaks of vaccine-preventable diseases (VPDs) around the globe have been partly attributed to a rise in vaccine hesitancy, thereby highlighting the significance of caregivers decision to delay or refuse vaccines for their children. Since 2014, the World Health Organization (WHO) member states have been annually reporting vaccine hesitancy reasons on the WHO/United Nations Children s Fund (UNICEF) Joint Reporting Form (JRF). The Vaccine Hesitancy Matrix (VHM), developed by the WHO Strategic Advisory Group of Experts on Immunization (SAGE) Vaccine Hesitancy Working Group, can serve as a tool to categorise vaccine hesitancy reasons reported in the JRF. This paper explores the reasons for vaccine hesitancy reported globa

Silver Embedded Plastic Packaging can Form Harmful Nanoparticles in Foods
Written by AZoNanoFeb 4 2021
Antimicrobial packaging is created to prolong the shelf life and ensure the safety of foods and beverages. But there is a concern regarding the leaching of possibly detrimental materials, like silver nanoparticles, from these kinds of containers into consumables.

Scientists have now described in
ACS Applied Materials & Interfaces that silver combined in an antimicrobial plastic can leach from the material and develop nanoparticles in foods and beverages, specifically in sweet and sugary foods.

Antimicrobial packaging is being developed to extend the shelf life and safety of foods and beverages. However, there is concern about the transfer of potentially harmful materials, such as silver nanoparticles, from these types of containers to consumables. Now, researchers reporting in
ACS Applied Materials & Interfaces illustrate that silver embedded in an antimicrobial plastic can leave the material and form nanoparticles in foods and beverages, particularly in sweet and sugary ones.
Some polymers containing nanoparticles or nanocomposites can slow the growth of microorganisms responsible for food and beverage spoilage and foodborne illness. Although these polymers are not currently approved for use in packaging in the U.S., researchers are investigating various types of nanoparti

Today, we released an analysis that investigated the loss or gain of scientific experts across multiple science-based federal agencies during the past four years. One thing was clear from the analysis the Environmental Protection Agency (EPA) took a hard hit, losing 672 scientific experts between 2016 and 2020 (see Figure 1). In fact, the EPA’s total workforce was down by 21% in 2018 compared to an all-time peak in staffing at the agency during 2000.
Figure 2. The EPA lost hundreds of scientists during the past four years on average, 219 scientists per year.
You might be wondering, “why should I care about a loss of scientists at the EPA?”
