The ocean’s ultimate trashcan: Hadal trenches as major depositories for plastic pollution

Water Research, 2020
Plastic debris and marine microplastics are being discharged into the ocean at an alarming scale and have been observed throughout the marine environment. Here we report microplastic in sediments of the Challenger Deep, the deepest known region on the planet, abyssal plains and hadal trenches located in the Pacific Ocean (4900 m-10,890 m). Microplastic

Identification of Free-living and Particle-Associated Microbial Communities Present in Hadal regions of the Mariana Trench

Frontiers in Microbiology, 2016
Relatively few studies have described the microbial populations present in ultra-deep hadal environments, largely as a result of difficulties associated with sampling. Here we report Illumina-tag V6 16S rRNA sequence-based analyses of the free-living and

Insight Into the Pico- and Nano-Phytoplankton Communities in the Deepest Biosphere, the Mariana Trench

Frontiers in Microbiology, 2018
As photoautotrophs, phytoplankton are generally present in the euphotic zone of the ocean, however, recently healthy phytoplankton cells were found to be also ubiquitous in the dark deep sea, i.e., at water depths between 2000 and 4000 m.

Global Analysis of Shallow Underwater Fish Observation Research: 70 Years of Progress, Persistent Geographic Biases and a Path Forward

Fish and Fisheries, EarlyView.
ABSTRACT Marine ecosystems are increasingly threatened by overfishing, pollution, coastal development and climate change, underscoring the need for long‐term, representative information on key fish populations and habitats to inform management and policy.

Single Cells within the Puerto Rico Trench Suggest Hadal Adaptation of Microbial Lineages [PDF]

Applied and Environmental Microbiology, 2015
ABSTRACT Hadal ecosystems are found at a depth of 6,000 m below sea level and below, occupying less than 1% of the total area of the ocean. The microbial communities and metabolic potential in these ecosystems are largely uncharacterized.

Organic matter degradation causes enrichment of organic pollutants in hadal sediments

Nature Communications, 2023
Burial of persistent organic pollutants (POPs) such as polychlorinated biphenyls (PCBs) in deep-sea sediments contributes to 60% of their historical emissions. Yet, empirical data on their occurrence in the deep-ocean is scarce.

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Calciprotein particle‐induced calcium overload triggers mitochondrial dysfunction in endothelial cells

The Journal of Physiology, EarlyView.
Abstract figure legend Calciprotein particles (CPPs) are small calcium‐ and phosphate‐containing nanoaggregates associated with the development of vascular disease (CVD) in chronic kidney disease (CKD). Previously, we have shown that CPPs induce endothelial cell (EC) dysfunction, possibly contributing to CVD in CKD, but the underlying molecular ...

Improving PARP inhibitor efficacy in bladder cancer without genetic BRCAness by combination with PLX51107

Molecular Oncology, Volume 20, Issue 3, Page 779-803, March 2026.
Clinical trials on PARP inhibitors in urothelial carcinoma (UC) showed limited efficacy and a lack of predictive biomarkers. We propose SLFN5, SLFN11, and OAS1 as UC‐specific response predictors. We suggest Talazoparib as the better PARP inhibitor for UC than Olaparib.

Ancestral Biogeography Reveals Diverse Origins of Costa Rica Margin Seep Invertebrates

Journal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim This work addressed the hypotheses that invertebrate species from hydrocarbon seeps at the Pacific Costa Rica Margin (CRM) would descend from adjacent biogeographic provinces, and that common ancestral histories would be identified across invertebrate groups.
