Organic carbon sources, transport, and mineralization in Kermadec Trench sediments

Frontiers in Marine Science
Hadal trenches are critical hotspots for organic carbon (OC) deposition and diagenesis, yet the mechanisms controlling carbon sequestration, particularly the role of episodic tectonic and volcanic events, remain poorly constrained.

Ice‐Nucleating Particle and Cloud Ice Crystal Concentrations Associated With Developing Summertime Deep Convective Clouds in South‐Western USA

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract Ice‐nucleating particles (INPs), essential for initiating primary ice production in many mixed‐phase clouds, have only rarely been measured in air directly relevant for deep convective clouds. In July–August 2022 we used an aircraft to sample aerosol near developing deep convective clouds over Magdalena Mountain, New Mexico, USA.

Morphological and molecular evolution of hadal amphipod’s eggs provides insights into embryogenesis under high hydrostatic pressure

Frontiers in Cell and Developmental Biology, 2022
Hadal zones are unique habitats characterized by high hydrostatic pressure (HHP) and scarce food supplies. The ability of eggs of species dwelling in hadal zones to develop into normal embryo under high hydrostatic pressure is an important evolutionary ...

Enhancing event stratigraphic correlations in the ultra‐deep Japan Trench using XRF‐CS cluster‐based chemostratigraphy

The Depositional Record, Volume 12, Issue 1, February 2026.
Cluster‐based chemostratigraphy using XRF‐CS enables high‐resolution correlation of event deposits across contrasting depositional settings in the Japan Trench. This approach reveals previously unrecognised events and compositional heterogeneity, offering new insights into sediment provenance and earthquake‐triggered deposition, with implications for ...

Whole genome sequencing of a snailfish from the Yap Trench (~7,000 m) clarifies the molecular mechanisms underlying adaptation to the deep sea.

PLoS Genetics, 2021
Hadal environments (depths below 6,000 m) are characterized by extremely high hydrostatic pressures, low temperatures, a scarce food supply, and little light.

Study on the Bacterial Communities of the Biofilms on Titanium, Aluminum, and Copper Alloys at 5,772 m Undersea in Yap Trench

Frontiers in Microbiology, 2022
Biofilms formed on metal surfaces strongly affect metallic instruments serving in marine environments. However, due to sampling difficulty, less has been known about the bacterial communities of the biofilm on metallic surfaces in hadal environments, so ...

A Lithospheric Drip Triggered Green and Colorado River Integration

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The integration of the Green and Colorado Rivers shifted the continental drainage divide of North America, marking a key event in the hydrological and biogeographical evolution of the continent. Sedimentological and stratigraphic evidence shows that for integration to occur, the Green River likely cut through the Uinta Mountains between 8 and ...

Microbiomes in the Challenger Deep slope and bottom-axis sediments

Nature Communications, 2022
The V-shaped Challenger Deep in the Mariana Trench is the deepest part of the world’s oceans. Using 586 prokaryotic metagenome-assembled genomes and metatranscriptomic data, this study explores metabolic capabilities and activities of microorganisms ...

Prior Knowledge Shaped Dutch Parents' Attitudes Towards the Use of Artificial Intelligence in Paediatrics

Acta Paediatrica, Volume 115, Issue 2, Page 473-481, February 2026.
ABSTRACT Aim European parental views on artificial intelligence (AI) in paediatrics remain underexplored. This study addressed this gap by examining Dutch parents' attitudes and assessing how prior knowledge and brief educational interventions influenced their acceptance.

Unravelling echinoid mass mortalities: a global overview of mechanisms, spatio‐temporal trends, and taxonomic insights

Biological Reviews, Volume 101, Issue 1, Page 221-236, February 2026.
ABSTRACT Mass mortality events (MMEs) have been occurring since the dawn of time. However, in contrast to terrestrial events, most marine MMEs remain undetected, largely due to the inaccessibility of many marine environments. One of the most notorious and best‐studied marine MMEs in modern times is that of the population collapse of the echinoid ...
