Summary: Human societies rely on marine ecosystems, which are still experiencing degradation. This article discusses the adaptation of sensors and wearable technology developed for humans to improve marine monitoring. It highlights the barriers to transitioning this technology from land to sea, updates on sensor developments for ocean observation, and advocates for wider use of wearables on marine organisms. The authors propose that widespread use of wearables could contribute to an 'internet of marine life' and inform strategies for marine conservation and restoration.

Summary: This article presents the development and implementation of an Internet of Maritime Things (IoMT) platform for remote and online marine water quality monitoring. The IoMT device and gateway are optimized for marine use and allow for long-range and high-rate communication. Additionally, an automatic beam adjustment system enables directional antennas to maintain communication even with sea undulation. Real sea experiments demonstrate that the proposed IoMT platform achieves significant performance improvements in terms of communication coverage compared to existing wireless networks.

Summary: This study successfully isolated bacteria capable of efficiently degrading oil, established a diesel degrading bacterial consortium with good capability of degrading short chain alkanes, and found that oil pollution has a selective effect on marine microorganisms. Although oil degradation was promoted after the addition of SA, the recovery of microbial community structure took a longer time.

Summary: Microplastics serve as a source of organic contaminants in aquatic environments, impacting their fate and toxicity. To assess the environmental risks associated with microplastics, a method for evaluating the dynamic uptake of organic contaminants onto suspended microplastics in water is necessary. In this study, a UV-vis spectroscopy-based approach was developed to monitor the uptake of organic contaminants onto suspended microplastics in real-time.

Summary: Platinum Group Elements (PGEs) are pollutants of concern due to their increasing use and release. This study investigated PGE contamination in marine organisms, focusing on rhodium (Rh). Samples were collected from two urbanized estuarine systems and adjacent coastal areas in Portugal. PGE concentrations were quantified using stripping voltammetry and mass spectrometry. The results showed that PGE contamination was correlated with urban effluents and influenced by traffic emissions and various sources. Macroalgae and mussels were found to be good bioindicators of PGE contamination in estuarine/coastal systems, reflecting urban pressure and amplifying environmental signals.

Summary: This study investigated the degradation potential of synthetic musks, UV filters, and a pharmaceutical compound in marine sediment samples under laboratory conditions. The results showed different half-life times for the contaminants under biotic conditions, with limitations observed in degradation under anoxic conditions compared to oxic conditions. Novel aerobic bacteria capable of degrading these contaminants were successfully isolated, potentially aiding in remediation processes in marine environments.

Summary: Traditionally, monitoring of aquatic ecosystems has relied on direct and indirect methods. However, advancements in smart devices and the Internet of Things offer new opportunities for accurate and precise measurements. Smart buoy networks, autonomous underwater vehicles, and multi-sensor microsystems have the potential to autonomously monitor marine environments and send alarm messages, but their impact on marine management is yet to be fully realized.

Summary: The management of dredged materials disposal is regulated by environmental normative requirements and supported by the integration of chemical data with ecotoxicological characterization. The reliability of a bioassay to assess toxicity of dredged sediments relies on the selection of quality criteria and the use of sea urchin embryo-toxicity bioassay is essential for evaluating sediment quality in harbour areas. The development and validation of Integrative Toxicity Indexes, particularly ITI 4.0, improves the causative relationship between sediment quality and sea urchin embryonic development.

Summary: Using environmental DNA (eDNA) to monitor biodiversity in aquatic environments is an efficient alternative to visual and acoustic identification. A new eDNA sampler, capable of self-cleaning and multi-sample capture, was tested alongside traditional collection methods and showed similar results. This sampler provides a robust alternative to manual sampling methods and enables persistent monitoring of remote sites.

Summary: The study found that halite-entombed archaeal communities are highly resilient to entombment durations of up to 21 weeks, suggesting it may be an effective survival strategy. Additionally, the dominance of certain 'halite specialists' observed in ancient halite likely requires years to develop, hinting at long-term successional dynamics in this environment.

Summary: Soil bacteria are expected to be more strongly influenced by pH than other edaphic and climatic factors, with potential implications for nutrient cycling and vegetation. Future forecasts of soil bacteria are essential, as predictions suggest a stronger role of pH in governing bacterial distribution despite small anticipated changes in bacterial communities. It is important to consider both edaphic and climate changes in future assessments of soil bacteria.

Summary: The study investigated the effects of environmental connectivity on natural soil microbial communities and found that while overall community growth was similar in high and low connectivity environments, low connectivity led to reduced microbial diversity due to increased negative interspecific interactions. This suggests the importance of environmental connectivity for microbial community dynamics and has implications for future interventions and restoration efforts.

Summary: This study found that dispersants and biosurfactants can significantly reduce the interfacial surface tension between water and oil within 24 hours, promoting an increase in the abundance of hydrocarbon-degrading bacteria and the rate of hydrocarbon biodegradation. Some dispersants or biosurfactants can selectively enhance specific bacterial genera, particularly rhamnolipid which shows compatibility with the Pseudomonas genus.

Summary: Periplasmic binding proteins are promising for designing sensor proteins with new recognition specificities, but computational design of new ligand-binding properties ignores the more general properties of these proteins. This study focused on the subcellular localization of ribose-binding protein (RbsB) in Escherichia coli and found that designed variants had defects in proper localization, which could impair sensor signaling.

Summary: This study aimed to understand the genetic factors contributing to the successful establishment of strain inoculation in nonsterile polluted soils. By generating mutant libraries and analyzing gene insertion abundances, it was found that many genes are important for the growth of Pseudomonas veronii in both liquid medium and soil. However, these genes are not specific to soil growth, indicating that P. veronii is a generalist that can proliferate well in soil environments.

Summary: Understanding the destiny of crude oil that enters the ocean is crucial in minimizing its negative impacts on the environment, economy, and society. Research has found that microbial degradation is a key process in removing hydrocarbons from oil, and turbulent seas and response measures can promote the growth of oil-degrading microorganisms. The discovery of bacteria attaching to oil droplets and reshaping them enhances our understanding of oil transport and biodegradation in ecologically sensitive areas.

Summary: This study aimed to understand the presence, distribution, and variation of ICEs related to ICEclc among P. aeruginosa clinical isolates. The results showed that most isolates carried one or more ICEclc-like elements with different degrees of conservation. Furthermore, the study also found evidence of clonal evolution and horizontal transfer of ICEs in the hospital environment.
