Advances in Linear Ultrasonic Motors.

Linear ultrasonic motors (LUSMs) occupy an important position in the field of high-precision actuation due to their advantages of simple structure, high control accuracy and direct linear motion gener...

Multinucleation as a recurring evolutionary strategy for scaling and plasticity.

Multinucleate cells - single cells containing multiple nuclei in a shared cytoplasm - are found across the eukaryotic tree of life. Having evolved independently in fungi, plants, protists, and animals...

Potential factors contributing to extreme longevity in the Greenland shark.

The Greenland shark (Somniosus microcephalus) is a deep-sea vertebrate inhabiting the cold waters of the North Atlantic and Arctic Ocean and is renowned for its exceptional longevity, with individuals...

First eDNA-based monitoring of marine vertebrates in the urban marine ecosystem of Abu Dhabi: Mangrove and seagrass beds as biodiversity reservoirs?

The Arabian Gulf is a semi-enclosed sea with shallow waters. Its marine fauna must cope with extreme and recurring environmental conditions (high summer temperatures, hypersalinity, hypoxia). In addit...

Motion-Induced Errors in Buoy-Based Wind Measurements: Mechanisms, Compensation Methods, and Future Perspectives for Offshore Applications.

Accurate measurement of sea-surface winds is critical for climate science, physical oceanography, and the rapidly expanding offshore wind energy sector. Buoy-based platforms-moored meteorological buoy...

Advancing sustainable seaweed production: linking technology, policy, and ecology for a resilient blue economy.

Seaweed cultivation is gaining global significance due to its nutritional, pharmaceutical, and environmental benefits. However, large-scale commercialization faces challenges such as processing ineffi...

Accurate time-series forecasting of floating platform motion via a reinforced fusion CNN-BiLSTM-attention model.

Accurate motion prediction of floating platforms is critical for ensuring operational safety in offshore engineering applications or marine equipment testing. However, the strong nonlinearity and non-...

Genomic and transcriptomic characterization of genes expressed at 20 MPa by the marine actinobacterium Kocuria flava.

A marine hydrocarbonoclastic actinobacterium Kocuria flava IOS11 was isolated from 3500 m deep-sea water of the Indian Ocean. The isolate efficiently degraded phenanthrene (250 mg/L) achieving 82 and ...

Can filamentous algae intensify heat in intertidal rockweed beds?

Intertidal rockweed beds are often described as climate refuges for species, buffering harsh environmental conditions. Due to problems such as ocean warming, ocean acidification, eutrophication and tr...

Warming transforms the western Arctic Ocean into a hub of drifting matter.

The Arctic Ocean is increasingly stressed by anthropogenic pollution and rapid environmental change. River discharge plays a crucial role in this transition by delivering freshwater, nutrients, carbon...

Enhancing microplastic monitoring with ships of opportunity to determine baselines: Methodological design matters.

Ships of opportunity provide a platform to assess marine pollution without dedicated field campaigns, offering a cost-effective means to expand monitoring coverage. In this study, a microplastic sampl...

Bathymetry and environmental features govern the microbial communities in mesopelagic sediments of the Lakshadweep Islands of India.

Predicting acoustic field with a separate variable ocean physics-informed neural network.

High-frequency underwater acoustic field modeling is challenging for physics-informed neural networks (PINNs) due to the strongly oscillatory nature of acoustic pressure fields. Building upon the Ocea...
