Published Researchers correlate Arctic warming to extreme winter weather in midlatitude and its future
(via sciencedaily.com) Original source A warmer Arctic has been linked to extreme winter weather in the midlatitude regions. But, it is not clear how global warming affects this link. In a new study, researchers show, using weather data and climate models, that while the 'Warm Arctic-Cold Continent' pattern will continue as the climate continues to warm, Arctic warming will become a less reliable predictor of extreme winter weather in the future.
Published Opening a new frontier: PdMo intermetallic catalyst for promoting CO2 utilization
(via sciencedaily.com) Original source A recently discovered catalyst, can convert carbon dioxide (CO2) into useful methanol at room temperature and low-pressure conditions. This novel compound, which is thermally and chemically stable in air, represents a new milestone in CO2 conversion via hydrogenation and could be key to slow down climate change.
Published Civil engineers use public satellite images to study why the Jagersfontein dam failed
(via sciencedaily.com) Original source Study by civil engineers finds that the history of the Jagersfontein dam deviates from best engineering practice.
Published New tool shows progress in fighting spread of invasive grass carp in Great Lakes
(via sciencedaily.com) Original source Researchers created a new way to estimate the abundance of invasive 'sleeper' species in freshwater ecosystems and help guide management strategies.
Published Preventing urban flooding in the face of climate change
(via sciencedaily.com) Original source Planners have come up with many innovative ways to prevent flooding caused by heavy downpours -- from planting rain gardens to installing green roofs. But in many cases, nothing works quite as well as a simple hole in the ground -- a detention basin.
Published New insights into engineering climate-smart crops for the future
(via sciencedaily.com) Original source New research in the field of plant sciences has made significant advances towards understanding the underlying reasons behind why certain crops are better at generating more yield than others.
Published Scientists use computational modeling to design 'ultrastable' materials
(via sciencedaily.com) Original source Researchers developed a computational approach to predict which metal-organic framework (MOF) structures will be the most stable, and therefore the best candidates for applications such as capturing greenhouse gases.
Published Sailing cargo ships can benefit from new aerodynamic tech
(via sciencedaily.com) Original source A research team has demonstrated a unique method that reduces the aerodynamic resistance of ships by 7.5 per cent. This opens the way for large cargo ships borne across the oceans by wind alone, as wind-powered ships are more affected by aerodynamic drag than fossil-fueled ones.
Published Researchers disentangle patterns of indoor mixing for respiratory disease transmission risk
(via sciencedaily.com) Original source Researchers have characterized the seasonal effects on human social behavior to provide new insights on the risk of respiratory disease transmission.
Published Legacy industrial contamination in the Arctic permafrost
(via sciencedaily.com) Original source A previously underestimated risk lurks in the frozen soil of the Arctic. When the ground thaws and becomes unstable in response to climate change, it can lead to the collapse of industrial infrastructure, and in turn to the increased release of pollutants. Moreover, contaminations already present will be able to more easily spread throughout ecosystems. According to new findings, there are at least 13,000 to 20,000 contaminated sites in the Arctic that could pose a serious risk in the future.
Published Insect decline also occurs in forests
(via sciencedaily.com) Original source The number of insects has been declining for years. This has already been well documented for agricultural areas. In forests, however, temporal trends are mostly studied for insect species that are considered pests. Now, a research team has studied the trends of very many insect species in German forests. Contrary to what the researchers had suspected, the results showed that the majority of the studied species are declining.
Published Limiting warming to 2°C may avoid 80% of heat-related deaths in Middle East and North Africa
(via sciencedaily.com) Original source Over 80% of predicted heat-related deaths in the Middle East and North Africa (MENA) by the end of the century could be prevented if global warming is limited to 2°C, according to a modelling study.
Published Warming Arctic draws marine predators northwards
(via sciencedaily.com) Original source Marine predators have expanded their ranges into the Arctic waters over the last twenty years, driven by climate change and associated increases in productivity.
Published Ocean warming intensifies viral outbreaks within corals
(via sciencedaily.com) Original source A groundbreaking three-year study in the South Pacific has found evidence that ocean warming can trigger outbreaks of 'dinoflagellate-infecting RNA viruses' that attack symbiotic algae inside corals. Coral reef viruses have gained greater attention since being implicated in 2021 as a possible cause of stony coral tissue loss disease that has decimated Florida and Caribbean reefs for almost a decade.
Published Researchers assemble pathogen 'tree of life'
(via sciencedaily.com) Original source Researchers provide open-access tool to capture new data on a global plant destroyer, Phytophthora.
Published Innovative method predicts the effects of climate change on cold-blooded animals
(via sciencedaily.com) In the face of a warming climate that is having a profound effect on global biodiversity and will change the distribution and abundance of many animals, a research team has developed a statistical model that improves estimates of habitat suitability and extinction probability for cold-blooded animals as temperatures climb.
Published Rising temperatures alter 'missing link' of microbial processes, putting northern peatlands at risk
(via sciencedaily.com) Researchers show that rising temperatures in northern regions may damage peatlands: critical ecosystems for storing carbon from the atmosphere -- and could decouple vital processes in microbial support systems.
Published Can cities make room for woodpeckers?
(via sciencedaily.com) Original source Researchers are deploying the latest mapping techniques to identify the most important suburban habitat for North America's largest woodpecker. Wildlife habitat in congested places is becoming increasingly fragmented as forests give way to new construction. Eventually, this could spell trouble to an animal with specific habitat needs like the pileated woodpecker.
Published Wastewater more potent breeding ground for antibiotic resistance than previously known
(via sciencedaily.com) Wastewater is a more potent environment for antibiotic resistance to evolve than previously known. A study shows that wastewaters have unique characteristics, allowing resistance genes to start their journey from harmless bacteria to those that cause disease.
Published Hope for salamanders? Study recalibrates climate change effects
(via sciencedaily.com) For tiny salamanders squirming skin-to-soil, big-picture weather patterns may seem as far away as outer space. But for decades, scientists have mostly relied on free-air temperature data at large spatial scales to predict future salamander distributions under climate change. The outlook was dire for the mini ecosystem engineers, suggesting near elimination of habitat in crucial areas.
