A machine learning approach to freshwater analysis

A team of researchers from Syracuse University and Texas A&M University applied a machine learning model to explore the sources of salinization and alkalinization in U.S. watersheds. The study found that human activities, such as road salt application, were major contributors to salinity, while natural processes dominated alkalinity.

Local loss of species may often be underestimated

A new biodiversity study shows that even seemingly healthy ecosystems with increasing species numbers may already be on the path to decline and loss of species. The study's findings suggest that species richness is not a reliable metric for monitoring ecosystems, as it can mask negative trends in species extinction.

Air quality stations have collected vast stores of DNA by accident, a potentially “game-changing” discovery for tracking global biodiversity

Researchers found an astonishing record of biodiversity trapped on air quality filter samples in the UK, including over 180 plant and animal species. The study suggests that existing air quality monitoring networks could be used to track terrestrial biodiversity on a continental scale.

Fallow land promotes bird diversity

A study found that establishing fallow land can increase the populations of farmland birds and improve biodiversity. The benefits depend on landscape complexity, particularly in regions with a moderate density of boundary lines between fields and woody structures.

CityU establishes the first UNESCO Regional Training and Research Centre on coastal contaminant monitoring in Hong Kong for the Western Pacific region

The City University of Hong Kong (CityU) has been approved to establish the first UNESCO Regional Training and Research Centre on coastal contaminant monitoring in Hong Kong, focusing on the Western Pacific region. The centre aims to strengthen marine pollution monitoring, promote innovative technologies, and facilitate international r...

Bioindicator for the occurrence of PFAS

A comprehensive study found that wild boar liver can be used as a bioindicator for PFAS contamination in the environment, detecting hot-spots in regions with elevated PFAS levels. The researchers discovered that PFAS concentrations are highest in areas where industrial activities and agricultural practices have led to contamination.

Wastewater sector emits nearly twice as much methane as previously thought

New research reveals that municipal wastewater treatment plants release significantly more methane into the atmosphere than previously estimated. The findings suggest that existing guidelines underestimate emissions equivalent to 5.3 million metric tons of carbon dioxide. Anaerobic digesters, used in some facilities, are particularly s...

Researchers propose a more effective method to predict floods

A team of researchers from Xi'an Jiaotong-Liverpool University and other institutions has identified a flexible and user-friendly model for predicting flood frequency in a changing environment. The fractional polynomial-based regression method is more effective than existing models, which often fail to account for factors like climate ...

‘Smart’ coating can be precisely applied to make fabric into protective gear

Dartmouth College researchers have developed a durable copper-based coating that can precisely be integrated into fabric to create responsive materials for protective equipment, environmental sensors, and smart filters. The coating responds to toxic gases in the air by converting them into less toxic substances trapped in the fabric.

Less intensively managed grasslands have higher plant diversity and better soil health, research shows for first time

Researchers found that less intensively managed grasslands had greater diversity of plant species and correlated with better soil health, including increased nitrogen and carbon levels. In contrast, intensively farmed plots showed fewer plant species, but some saw improvements in soil health over time.

Seeing concentrations of toxins with the naked eye

Researchers developed a fast and cost-effective method to detect amphiphiles, a ubiquitous family of chemical compounds used in disease diagnosis and toxin detection. The new test uses rolling droplets on microstructured surfaces to detect levels of pathogenic endotoxins in water at ultralow concentrations.

Soil temperature can predict pest spread in crops

A new study from North Carolina State University shows that soil temperature can be used to predict the spread of the corn earworm, an important pest affecting various crop species. The research reveals three geographic zones where the pest can overwinter, and models suggest that these zones will shift northward due to climate change.

Keeping Kermit: New clues to protecting frogs from deadly Bd fungus

A new study from the University of South Australia shows that captive frogs can be protected from the deadly fungus Batrachochytrium dendrobatidis (Bd) through natural skin shedding processes. However, captivity also reduces skin bacteria diversity and richness, potentially affecting the frogs' resilience to pathogens.
