To the Editor — It has been argued that that we are currently facing the sixth mass extinction event1, and the ubiquitous use of chemicals is one major driver for this loss of biodiversity2. Ecotoxicology, the estimation of environmental risks imposed by chemicals, is therefore an essential backbone for adequate mitigation efforts by stakeholders. However, […] More
Construction of tricolor fluorescent reporter strains Tricolor fluorescent reporters were constructed in the marine model organism R. pomeroyi DSS-3 (wild-type strain, a gift from Prof. M. A. Moran, University of Georgia) to visually report expression of DMSP degradation genes (dddW and dmdA). DddW was chosen due to its strong upregulation response to DMSP reported in […] More

Genomic similarity within bacterial populations is spatially organized across a meadow Starting with an undereplicated but quality filtered dataset of 3215 draft quality genomes assembled from samples collected from across the meadow [29], we calculated all pairwise genome-wide average nucleotide identities (ANI) and alignment coverages (roughly analogous to shared gene content; Fig. 1b). We observed a […] More

In March 2011, large amounts of radionuclides were released into the environment as a result of an accident at Tokyo Electric Power Company’s Fukushima Daiichi Nuclear Power Plant (FDNPP). Approximately 13–15 PBq of caesium-137 (hereinafter, 137Cs, physical half-life of 30 years) was released from the FDNPP accident1,2, and as a result, 137Cs became a major […] More
