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.
