Biosphere expansion drives Earth's secular oxygenation while tectonics modulate oxygen variability revealed by machine learning.

The rise of atmospheric oxygen fundamentally transformed Earth's surface environment and enabled the evolution of complex life. However, the processes driving long-term oxygen fluctuations remain poor...

Fishing trawlers drive the fine-scale daytime distribution of bottlenose dolphins at the Tiber River estuary (Western Mediterranean Sea).

Fisheries can strongly alter marine ecosystem dynamics, influencing the ecology and behaviour of top predators such as cetaceans. At the Tiber River estuary (Tyrrhenian Sea, Western Mediterranean), bo...

Host matters: coral reef fish species show distinct skin microbiome responses to upwelling-driven environmental changes.

Microbes from ambient-pressure analogues offer insights into possible life in Europa's high-pressure subsurface ocean.

Under its thick ice layer, Europa contains a shielded liquid water ocean where habitable conditions may exist. To effectively assess the habitability of this environment and the implications on putati...

A new species of deep-sea fouling Hyalopomatus (Annelida: Serpulidae) from the Mexican Pacific.

A new species of tubeworm belonging to the genus Hyalopomatus (Serpulidae) is described from the southern Mexican Pacific. It was found in 2024 attached to a seismograph at nearly 1000 m depth. The ne...

Environmental DNA metabarcoding complements bottom trawling and detects fish species beyond recorded ranges in the Chukchi Borderland, Central Arctic Ocean.

Global climate change is profoundly altering Arctic marine biodiversity, yet baseline data on fish assemblages in the central Arctic Ocean remain critically scarce. The Chukchi Borderland-a Pacific-At...

Evaluation of geophysical and anthropogenic sources of hydroacoustic noise in the Alaskan arctic.

Quantifying the ocean soundscape is crucial for ocean-based seismoacoustic monitoring; it sets a baseline for the kinds and sizes of signals that can be detected above the background noise. As sea ice...

Advanced Triboelectric Nanogenerators for Smart Devices and Emerging Technologies: A Review.

Smart devices and emerging technologies are highly popular devices and technologies that considerably improve our daily living by reducing or replacing human workforces, treating disease, monitoring h...

Archaea-driven bioremediation of polyolefins and polyesters in extreme environments.

Global plastic production surpassed 436 million metric tonnes in 2023, with polyolefins, polyethylene and polypropylene, and polyesters, polyethylene terephthalate and polybutylene adipate terephthala...

Enhancing catalytic efficiency of a deep-sea alkaline lipase through integrated engineering of lid-associated dynamics.

A deep-sea alkaline lipase, MyLip2, fromMoritella yayanosiiwas identified from a metagenomic library of 1,048,576 genes. The wild-type enzyme preferred medium- to long-chain p-nitrophenyl esters, with...

Syntrophic interactions driving anaerobic methane oxidation in deep-sea cold seeps revealed by DNA-SIP.

Anaerobic oxidation of methane is a key process reducing methane emissions in oxygen-depleted marine environments such as deep-sea cold seeps. However, the stability and adaptability of microbial inte...

Associating contaminant risks with land use changes over time.

Throughout the Pacific Islands land use changes have resulted in intensified contaminant impacts that threaten the integrity of coastal ecosystems and communities. Pu'uloa (Pearl Harbor) in Hawai'i of...

Microplastic extraction method optimisation in solid marine matrices, to preserve integrity and polymer recovery.

The development of effective methodologies for extracting microplastics from marine matrices is key for designing appropriate measures to reduce and mitigate their effects. The diversity of protocols ...

Wildfire ash impacts the early development of the sea urchin Paracentrotus lividus.

The Mediterranean Basin is facing an increasing frequency and intensity of wildfires driven by climate change, raising concern about their off-site impacts on marine ecosystems. This study provides fo...

Exploring factors shaping the craniomandibular shape of extant walrus.

As both iconic Arctic megafauna and long-exploited marine resources, walruses (Odobenus rosmarus) have left an abundant osteological record across the Holarctic. However, distinguishing sex, ontogenet...

Beyond Global Replanning: Hierarchical Recovery for Cross-Device Agent Systems

Real-world computer-use tasks often span multiple applications and devices, requiring agents to coordinate heterogeneous environments under dynamic runtime failures. Existing multi-device agent system...

Improving ecological inference and uncertainty quantification from camera trap data through the fusion of AI confidences and manual annotations

Camera traps have become a core tool in ecological research, enabling large-scale, noninvasive monitoring of wildlife populations and behavior. By automatically recording animals as they pass within v...

Paleoenvironmental Stasis for the Bioturbating Community During the Paleocene-Eocene Thermal Maximum at the Southern Iberian Margin.

During the Paleocene-Eocene Thermal Maximum (PETM), there was an increase in global temperatures and emissions of isotopically depleted carbon, resulting in a negative carbon isotope excursion (CIE). ...

Biohybrid Robotic Jellyfish for Swimming-Enhanced Vertical Ocean Profiling.

Ocean monitoring is essential for understanding climate change and marine ecosystem dynamics, yet achieving comprehensive global coverage remains a challenge in oceanography. Current technologies face...

Deciphering the evolutionary history of ectoine catabolism, a compatible solute utilized by Vibrio diabolicus as an osmoprotectant and a nutrient source.

Bacterial adaptation to fluctuations in salinity includes the intracellular accumulation of organic compounds called compatible solutes (CS) such as the amino acid derivatives ectoine and 5-hydroxyect...
