Induced polarization monitoring of in-situ chemical oxidation for quantification of contaminant consumption.

Dynamic monitoring of in-situ chemical oxidation (ISCO) of LNAPLs in groundwater is the foundation for evaluating remediation effectiveness. In this study, spectral (SIP) and time-domain induced polarization (TDIP) measurements are conducted in laboratory columns and sandboxes to monitor the ISCO of LNAPL for characterizing oxidant transport and quantifying contaminant consumption under different injection strategies. To support the interpretation, this was combined with total petroleum hydrocarbon (TPH), hydrochemistry and computed tomography (CT) measurements.

Colonoscopy Assisted Laparoscopic Wedge Resection for Colonic Lesions: Impact on Quality of LifE: Results from the LIMERIC Study.

Background: The LIMERIC study has proven that colonoscopy-assisted laparoscopic wedge resection effectively and safely removes benign colonic lesions unsuitable for endoscopic removal, thereby avoiding the need for major surgery.

Objective: To evaluate the impact of colonoscopy-assisted laparoscopic wedge on health-related quality of life of patients who participated in the LIMERIC study.

Design: Prospective multicenter study.

Scientists' call to action: Microbes, planetary health, and the Sustainable Development Goals.

Microorganisms, including bacteria, archaea, viruses, fungi, and protists, are essential to life on Earth and the functioning of the biosphere. Here, we discuss the key roles of microorganisms in achieving the United Nations Sustainable Development Goals (SDGs), highlighting recent and emerging advances in microbial research and technology that can facilitate our transition toward a sustainable future. Given the central role of microorganisms in the biochemical processing of elements, synthesizing new materials, supporting human health, and facilitating life in managed and natural landscapes, microbial research and technologies are directly or indirectly relevant for achieving each of the SDGs.

Temperature modulates dominance of a superinfecting Arctic virus in its unicellular algal host.

Complex virus-virus interactions can arise when multiple viruses coinfect the same host, impacting infection outcomes with broader ecological and evolutionary significance for viruses and host. Yet, our knowledge regarding virus competition is still limited, especially for single-celled eukaryotic host-virus systems. Here, we report on mutual interference of two dsDNA viruses, MpoV-45T and MpoV-46T, competing for their Arctic algal host Micromonas polaris.
