Surveillance of Acute Respiratory Infections Using Community-Submitted Symptoms and Specimens for Molecular Diagnostic Testing

The GoViral platform evaluated whether a cohort of lay volunteers could, and would find it useful to, contribute self-reported symptoms online and to compare specimen types for self-collected diagnostic information of sufficient quality for respiratory infection surveillance.

Tellurite Adsorption onto Bacterial Surfaces.

Analysis of surface-associated molecules shows that the EPS of B. subtilis contain proteins, which indicates that sulfhydryl binding in EPS plays a key role in tellurite adsorption on bacterial surfaces.

Tellurate enters Escherichia coli K-12 cells via the SulT-type sulfate transporter CysPUWA

Results indicate that tellurate enters E. coli cells to cause toxic effects via the CysPUWA sulfate transporter, and that implementation of the mutation restored tellurate sensitivity and uptake.

The role of cysteine in tellurate reduction and toxicity

Exposure of E. coli K-12 to tellurate results in reduction to elemental tellurium (Te[0]) and the formation of intracellular reactive oxygen species (ROS) and the source of ROS in the cytoplasm of tellurate-exposed cells is indicated.

Dispersing male Parnassius smintheus butterflies are more strongly affected by forest matrix than are females

Comparing the dispersal patterns of male and female Parnassius smintheus among 18 subpopulations over 8 years using the Virtual Migration Model finds males and females are predicted to respond in similar ways to reduced meadow area and increased forest isolation.

Direct estimates of metapopulation capacity from dispersal show high interannual variability, but little effect of recent forest encroachment on network persistence

Context Habitat loss and isolation are leading threats for biodiversity. Alpine habitat throughout the world is being lost and fragmented by forest encroachment. Previous analysis of forest…

Role of extracellular reactive sulfur metabolites on microbial Se(0) dissolution

The findings suggest that the production of reactive sulfur metabolites by soil microorganisms and the formation of soluble selenosulfur complexes can promote selenium mobilization during chemical weathering.

Anoxic photochemical weathering of pyrite on Archean continents

Sulfur is an essential element of life that is assimilated by Earth’s biosphere through the chemical breakdown of pyrite. On the early Earth, pyrite weathering by atmospheric oxygen was severely…
