In this study, we show that climate change mitigation does not necessarily have to come at the cost of employment. The deployment of BECCS by 2030 and the replacement of 50% of aging coal plants with natural gas allow achieving emission reductions consistent with 2 C stabilization pathways in the coal sector by 2050. This strategy addresses the concerns surrounding coal workers' employment by phasing out coal gradually, retaining 40,000 jobs, and creating 22,000 additional jobs by mid-century.
Enhancements in swabbing technology to increase sample collection efficacy would benefit the food industry. Specifically, these enhancements would assist the food industry in implementing the FDA Food Safety Modernization Act (FSMA) requirements by improving environmental monitoring effectiveness. A sonicating swab device, an example of an enhanced swabbing technology, was demonstrated previously to remove biofilm from stainless steel more efficiently than a standard cotton swab. Within this study, the performance of the sonicating swab was compared to that of the standard cotton swab for the recovery of from inoculated surfaces (plastic cutting board, wood cutting board, vinyl floor tile, and quarry clay floor tile). Additionally, we demonstrate the sonicating swab performance for collection of a microbiological sample from used commercial plastic cutting boards (noninoculated) in comparison to cotton swabs, foam swabs, and sponges. The sonicating swab captured significantly ( ≤ 0.05) more than the cotton swab for both the quarry tile and wood cutting board, while no significant differences were observed for the plastic cutting board or the vinyl floor tile. The sonicating swab consistently recovered significantly ( ≤ 0.05) more bacteria from the used cutting boards than did the standard cotton swab or the 3M Enviro swab, and it recovered significantly ( ≤ 0.05) more bacteria than the sponge swab for a majority of the time (4 of 6 trials). The results of this study indicate that swab technology can still be improved and that the sonicating swab is a viable technological enhancement which aids microbiological sample collection. Swabbing of surface areas for microbial contamination has been the standard for the detection and enumeration of microorganisms for many years. Inadequate surface sampling can result in foodborne illness outbreaks due to biotransfer of harmful microorganisms from food contact surfaces to foods. Swab material type, surface characteristics, and swabbing method used are a few of the factors associated with swabbing that can result in the variability of bacterial cell recovery for detection and enumeration. A previous study highlighted a sonicating swab prototype and its ability to recover cells from a stainless steel surface more efficiently and reliably than a standard swab method (T. A. Branck, M. J. Hurley, G. N. Prata, C. A. Crivello, and P. J. Marek, Appl Environ Microbiol 83:e00109-17, 2017, https://doi.org/10.1128/AEM.00109-17). This study expands upon the capabilities of the sonicating swab technology to recover cells from multiple surface types with increased performance over traditional swabbing methods as a tool to further assist in the prevention of foodborne illness outbreaks.
Maintaining biodiversity is crucial for ensuring human well-being. We participated in a workshop held in Palenque, Mexico, in August 2018, that brought together thirty mostly early-career scientists working in different disciplines (natural, social and economic sciences) with the aim of identifying research priorities for studying the contributions of biodiversity to people and how these contributions might be impacted by environmental change. Five main groups of questions emerged: (1) Enhancing the quantity, quality, and availability of biodiversity data; (2) Integrating different knowledge systems; (3) Improved methods for integrating diverse data; (4) Fundamental questions in ecology and evolution; and (5) Multi-level governance across boundaries. We discuss the need for increased capacity building and investment in research programs to address these challenges.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
