A study of over 97 citizen scientists found that coastal areas have significantly more litter than inland locations, with urban areas consistently exhibiting more litter than rural areas. The research highlights the need for tailored waste management strategies to address regional differences in litter patterns.
Researchers developed a machine-learning tool that provides accurate predictions for flood-prone areas, using historical data and weather-based predictors. The model can predict short-term river discharge with high accuracy, giving real-time data on water movement through the river.
Researchers from USTC discovered that current sheets in magnetosheath originate from fast magnetosonic waves excited by ion resonance instability, leading to magnetic reconnection and energy dissipation. The study provides insights into the formation mechanism of coherent current sheet structures in turbulent plasma.
Researchers found that streams with ample groundwater connections have greater microbial diversity and are more effective at preventing toxic metal entry. They also better detoxify existing metals.
Researchers at State University of Campinas discovered genes favoring colossal growth in whales also inhibit cancer development. The study found that certain regulatory regions influence both size and cancer suppression, offering new insights into the evolution of cetacean gigantism.
Researchers at Hokkaido University discovered a novel sex-determination mechanism in the Amami spiny rat, a species lacking the Y chromosome and Sry gene. The mechanism involves the upregulation of Sox9 gene on chromosome 3, induced by a new regulatory element similar to Enh14.
The Mekong delta, Southeast Asia's most productive agricultural region and home to 17 million people, is at risk of disappearing by the end of the century due to subsidence. Sediment loss from upstream dams and poor water management exacerbates the issue, threatening food security and livelihoods.
New research suggests the UK's pandemic planning was limited by an outdated modelling structure, highlighting the need for a more holistic approach to decision-making. Professor Ashraf Labib proposes a hybrid model combining resilience triangle and bowtie modelling with five guiding principles to enhance public policy decisions.
Researchers found eDNA sampling to be more accurate than electrofishing in detecting coastal cutthroat trout populations, revealing fish up to 250 meters upstream. EDNA detection is a useful complement to electrofishing but not a replacement, offering less disruption and fewer permits required.
A study by the University of Helsinki and colleagues found that salmon from the Tornio and Kalix Rivers in Finland and Sweden have distinct migration patterns and ages, but no clear genetic differences. The research highlights the need for cross-border cooperation to conserve the largest wild Baltic salmon stocks.
Researchers developed a new method to analyze sediment in mountain rivers to determine landslide frequency and residence time, revealing that most sediment remains in the river system for only ten years. This study has significant implications for understanding and mitigating landslide risk in mountainous regions.
A study published in River Research and Applications detected over 1,000 endangered razorback sucker and dozens of Colorado pikeminnow downstream of the Piute Farms Waterfall. The fish moved from up to 600 miles away in the Colorado River, suggesting that spawning migrations may be cut off by the waterfall.
A study of waterfalls found that river bed rock composition plays a crucial role in shaping the surrounding landscape over time. The research revealed that changes to the river bed material significantly impact how quickly waterfalls migrate upstream.
Researchers at Michigan State University have developed a new database and algorithm to analyze upstream data, enabling the management of stream health across large landscapes. The system allows for rapid analysis of 2.6 million stream reaches in the contiguous United States, reducing analysis time from weeks to just five hours.
