An Overview of the Mississippi Farm and Food Economy

This report provides an overview of the farm and food economy of Mississippi, outlining the realities faced by farmers, food workers, and consumers in Mississippi. An estimated 90% (or more) of the food consumed in the state is sourced outside of Mississippi. More than half of the population is overweight. 12.4% of the population has diabetes — the largest rate in the U.S. In response to these trends, many small but potent collaborations are beginning to form, largely below the radar. Striking new farming models are being created at the grassroots. Amidst a climate that is relatively dismissive, these innovators have built strong businesses by constructing solid networks around themselves. Participants in these emerging collaborations often are deeply skeptical of the potential for the public sector to play a positive role. Yet despite this skepticism, their work must be embraced and supported by the state of Mississippi, with the creation of supportive infrastructure, and proper incentives

Centering Racial Justice to strengthen the Public Health Ecosystem

The public health field experienced a collective "moment" in 2020, declaring racism a public health crisis in cities, counties, and states across the country. However, since then, too many have slipped back to "business as usual." The new report Centering Racial Justice to Strengthen the Public Health Ecosystem: Lessons from COVID-19 from Prevention Institute and Big Cities Health Coalition calls on us all to reignite our collective commitment to bold transformational change rooted in equity and racial justice

Different Electrochemical Sensor Designs Based on Diazonium Salts and Gold Nanoparticles for Pico Molar Detection of Metals

International audienceWe report a comparison of sensors' performance of different hybrid nanomaterial architectures modifying an indium tin oxide (ITO) electrode surface. Diazonium salts and gold nanoparticles (AuNPs) were used as building units to design hybrid thin films of successive layers on the ITO electrode surface. Different architectures of hybrid thin films were prepared and characterized with different techniques, such as TEM, FEG-SEM, XPS, and EIS. The prepared electrodes were used to fabricate sensors for heavy metal detection and their performances were investigated using the square wave voltammetry (SWV) method. The comparison of the obtained results shows that the deposition of AuNPs on the ITO surface, and their subsequent functionalization by diazonium salt, is the best performing architecture achieving a high sensitivity in terms of the lower detection limit of pico molar
