How Arctic sea ducks develop herd immunity from avian cholera
Herd immunity, when a threshold proportion of a population becomes immune to a disease-causing organism, reducing or stopping further transmission, is very much in the news. Avian cholera much less so. But there is an intersection between these two s.....»»
Human cases of H5N1 confirmed in California amid rapid dairy spread
The CDC confirmed two new bird flu cases, bringing the human tally to 17. Two California dairy farm workers who had contact with H5N1-infected cows have contracted an H5 avian inf.....»»
How future heat waves at sea could devastate UK marine ecosystems and fisheries
The oceans are warming at an alarming rate. 2023 shattered records across the world's oceans, and was the first time that ocean temperatures exceeded 1°C over pre-industrial levels. This led to the emergence of a series of marine heat wave events ac.....»»
Scientists develop novel method for strengthening PVC products
Researchers have developed a way to make one type of plastic material more durable and less likely to shed dangerous microplastics. Their study has identified a secure way to attach chemical additives to polyvinyl chloride (PVC). The work is publishe.....»»
The true global impact of species-loss caused by humans is far greater than expected, study reveals
The extinction of hundreds of bird species caused by humans over the last 130,000 years has led to substantial reductions in avian functional diversity—a measure of the range of different roles and functions that birds undertake within the environm.....»»
Mathematicians and climate researchers build new models for understanding polar sea ice
Polar sea ice is ever-changing. It shrinks, expands, moves, breaks apart, reforms in response to changing seasons, and rapid climate change. It is far from a homogenous layer of frozen water on the ocean's surface, but rather a dynamic mix of water a.....»»
Decades-long research reveals new understanding of how climate change may impact caches of Arctic soil carbon
Utilizing one of the longest-running ecosystem experiments in the Arctic, a Colorado State University-led team of researchers has developed a better understanding of the interplay among plants, microbes and soil nutrients—findings that offer new in.....»»
Researchers develop Biodiversity Digital Twins to model our planet"s life
Biodiversity is essential for the processes that support all life on Earth. It provides critical resources such as food and energy, and supports ecosystem health. However, climate change, deforestation, and pollution are destroying habitats, altering.....»»
Arctic plant study suggests the rate of climate change threatens to exceed the adaptive capacity of species
A research group at the Finnish Museum of Natural History is investigating the adaptive potential of plant species amid a warming climate. Their recent study investigates the Siberian primrose, a plant species that occurs on the coasts of the Bothnia.....»»
Scientists develop a new model of electric double layer
A new model accounts for a wide range of ion-electrode interactions and predicts a device's ability to store electric charge. The model's theoretical predictions align with the experimental results. Data on the behavior of the electric double layer (.....»»
Researchers develop first banana plant resistant to TR4 and black sigatoka
Researchers have developed a banana plant that is resistant to both fusarium tropical race 4 (TR4) and black sigatoka, two of the most destructive diseases for bananas......»»
New findings can help improve our understanding of winter weather in the St. Lawrence River Valley
A recent study at McGill University provides new insights into how winter storms develop in the St. Lawrence River Valley, findings that could potentially improve the accuracy of winter weather forecasts in the region......»»
Scientists highlight overlooked threats to Arctic coasts amid climate change
As climate change rapidly transforms Arctic marine systems, the dramatic image of a polar bear struggling on a melting ice floe has become symbolic of the region's environmental crisis. But scientists argue that coastal Arctic ecosystems are undergoi.....»»

Researcher develops program for 3D cloud tomography
Researcher David Stanley's interest in climate change has led him to develop a program to improve how we gather data to study the inside of a cloud. The program simulated multiple satellites, collecting images of a cloud from many angles at the same.....»»
Study tracks traveling population wave in Canada lynx
A new study by researchers at the University of Alaska Fairbanks's Institute of Arctic Biology provides compelling evidence that Canada lynx populations in Interior Alaska experience a "traveling population wave" affecting their reproduction, movemen.....»»
Retracing walrus ivory trade of Viking Age reveals early interactions between Europeans and Indigenous North Americans
By examining ancient walrus DNA, an international research team led by Lund University in Sweden have retraced the walrus ivory trade routes of the Viking Age. They found that Norse Vikings and Arctic Indigenous peoples were probably meeting and trad.....»»

Scientists develop method to control timing of synthetic DNA droplet division
Many cellular functions in the human body are controlled by biological droplets called liquid-liquid phase separation (LLPS) droplets. These droplets, made of soft biological materials, exist inside living cells but are not enclosed by membranes like.....»»
Ice cores show pollution"s impact on Arctic atmosphere
A Dartmouth-led study on ice cores from Alaska and Greenland found that air pollution from the burning of fossil fuels reaches the remote Arctic in amounts large enough to alter its fundamental atmospheric chemistry. The findings illustrate the long.....»»
Arctic sea ice near historic low; Antarctic ice continues decline
Arctic sea ice retreated to near-historic lows in the Northern Hemisphere this summer, likely melting to its minimum extent for the year on Sept.11, 2024, according to researchers at NASA and the National Snow and Ice Data Center (NSIDC). The decline.....»»
