Today’s digest covers a range of topics including a duplex qPCR assay to detect lung infections, an investigation into sand fly symbionts, and a characterization of a fermented soybean food (Pe poke). If you want to end the week on a good note, I’d suggest reading the two articles I’ve highlighted below. One demonstrates that flooding and ecological restoration of former cranberry farmland also restores wetland microbial communities and soil function. The second provides a new barcoding strategy for the phenotypic screening of mosquitos that can be applied towards malaria research.

Happy reading!

Happy December from Pittsburgh!

Today’s digest includes original research on the impacts of fungal entomopathogens on Wolbacia infections and the influence of nutrient status on the response of a diatom to oil and dispersant. I have also included a study protocol for oral microbiome transplant for the treatment of dental caries and periodontal disease as well as preprints on a variety of topics. Finally, I want to highlight two articles I included that are little different from my usual content: the first is on predictors of willingness to receive the COVID-19 vaccination and the second is focused on transparency in peer review.

Greetings from Pittsburgh!

Today’s digest is heavy on plant and soil-associated research. It includes a review on the use of metagenomics in soil ecology research, original research focused on the microbiome of plants growing in a Sandhills ecosystem, as well as articles focused on the soil-associated microorganisms Marinobacter caseinilyticus sp. and Dickeya sp. This digest also features several articles focused on extremophiles found in permafrost, the South Pole, and a Mars-like environment! Finally, I also wanted to highlight an Q&A with Dr. Kizzmekia Corbett, an immunologist at the National Institute of Health and one of the designers of the Moderna COVID-19 vaccine.
