Researchers conducted epidemiologic and genomic studies to investigate in-flight SARS-CoV-2 infection associated with repatriation flights from India to Australia in April 2021.
Prokaryotes constitute the majority of sedimentary biomass, where they cycle organic carbon and regulate organic matter transformation. The microbes inhabiting sediment are diverse, and the factors controlling microbial community composition are not fully understood. Here, we characterized the prokaryotic community using 16S rRNA gene sequencing in 24 stratigraphic layers within a 89 cm (dated to ~1900 years old) sediment core from an anchialine sinkhole in the Bahamas with a stratified water column and anoxic bottom water. The microbial community was dominated by members of the Alphaproteobacteria, Dehalococcoidia, Gammaproteobacteria, Bathyarchaeota, and Campylobacter classes. Most interestingly, subsurface microbial community structure could be correlated to previous evidence for timewise changes in the main source of organic matter that was supplied to the sediment accumulating during the last 2000 years, which itself was caused by regional terrestrial vegetation changes.

A new medical paper has reported what it believed to be the first case of Covid-19 reinfection in the Republic of Ireland.
A report in the Irish Medical Journal details the case of a 40-year-old health care worker, who was confirmed to be infected with the virus for the second time, seven months after her first infection.
