Published Energy trades could help resolve Nile conflict
(via sciencedaily.com) Original source Scientists have shed light on a new, transformative approach that could help resolve a dispute over the Nile river's water resources.
Published How geography acts as a structural determinant of health
(via sciencedaily.com) Original source In unincorporated communities in the United States-Mexico borderlands, historically and socially marginalized populations become invisible to the healthcare system, showing that geography acts as a structural determinant of health for low-income populations.
Published Scientists capture X-rays from upward positive lightning
(via sciencedaily.com) Original source Researchers have for the first time recorded X-rays being produced at the beginning of upward positive lightning flashes; an observation that gives important insight into the origins of this rare -- and particularly dangerous -- form of lightning.
Published Anthropologist documents how women and shepherds historically reduced wildfire risk in Central Italy
(via sciencedaily.com) Original source Fire management lessons from the past could help to improve resilience as the Mediterranean faces increased fire risk from climate change. How traditional land management practices once greatly reduced fuel for wildfires, and how these practices were forgotten, in part due to historical politics of classism and sexism.
Published Genetic hope in fight against devastating wheat disease
(via sciencedaily.com) Original source Fungal disease Fusarium head blight (FHB) is on the rise due to increasingly humid conditions induced by climate change during the wheat growing season, but a fundamental discovery could help reduce its economic harm.
Published AI deciphers new gene regulatory code in plants and makes accurate predictions for newly sequenced genomes
(via sciencedaily.com) Original source Elucidating the relationship between the sequences of non-coding regulatory elements and their target genes is key to understanding gene regulation and its variation between plant species and ecotypes. Now, an international research team developed deep learning models that link gene sequence data with mRNA copy number for several plant species and predicted the regulatory effect of gene sequence variation.
Published Recovering phosphorus from sewage sludge ash
(via sciencedaily.com) Original source Chemical and heat treatment of sewage sludge can recover phosphorus in a process that could help address the problem of diminishing supplies of phosphorus ores.
Published New offshore wind turbines can take away energy from existing ones
(via sciencedaily.com) Original source Interactions between wind turbines could reduce power output by 30% in proposed offshore wind farm areas along the East Coast, new research has found. In all, the farms could still meet 60% of the electricity demand of New England.
Published Barley plants fine-tune their root microbial communities through sugary secretions
(via sciencedaily.com) Original source Different types of barley recruit distinct communities of soil microbes to grow around their roots by releasing a custom mix of sugars and other compounds, according to a new study.
Published Food in sight? The liver is ready!
(via sciencedaily.com) Original source What happens in the body when we are hungry and see and smell food? A team of researchers has now been able to show in mice that adaptations in the liver mitochondria take place after only a few minutes. Stimulated by the activation of a group of nerve cells in the brain, the mitochondria of the liver cells change and prepare the liver for the adaptation of the sugar metabolism. The findings could open up new avenues for the treatment of type 2 diabetes.
Published Voluntary corporate emissions targets not enough to create real climate action
(via sciencedaily.com) Original source Companies' emissions reduction targets should not be the sole measure of corporate climate ambition, according to a new perspective paper.
Published Curiosity promotes biodiversity
(via sciencedaily.com) Original source Cichlid fishes exhibit differing degrees of curiosity. The cause for this lies in their genes, as reported by researchers. This trait influences the cichlids' ability to adapt to new habitats.
Published Estimating emissions potential of decommissioned gas wells from shale samples
(via sciencedaily.com) Original source Extracting natural gas from shale formations can provide an abundant, lower-carbon footprint fossil fuel, but also creates concerns over increased methane emissions. Researchers have now developed a new tool that can estimate the emission potential of shale wells after they are no longer active.
Published The longer spilled oil lingers in freshwater, the more persistent compounds it produces
(via sciencedaily.com) Original source Oil is an important natural resource for many industries, but it can lead to serious environmental damage when accidentally spilled. While large oil spills are highly publicized, every year there are many smaller-scale spills into lakes, rivers and oceans. The longer that oil remains in freshwater, the more chemical changes it undergoes, creating products that can persist in the environment.
Published Warming Arctic reduces dust levels in parts of the planet
(via sciencedaily.com) Original source Dust can have a huge impact on local air quality, food security, energy supply and public health. Previous studies have found that dust levels are decreasing across India, particularly northern India, the Persian Gulf Coast and much of the Middle East, but the reason has remained unclear. Researchers found that the decrease in dust can be attributed to the Arctic warming much faster than the rest of the planet, a phenomenon known as Arctic amplification. This process destabilizes the jet stream and changes storm tracks and wind patterns over the major sources of dust in West and South Asia.
Published Scientists replace fishmeal in aquaculture with microbial protein derived from soybean processing wastewater
(via sciencedaily.com) Original source Scientists have successfully replaced half of the fishmeal protein in the diets of farmed Asian seabass with a 'single cell protein' cultivated from microbes in soybean processing wastewater, paving the way for more sustainable fish farming practices.
Published Key to efficient and stable organic solar cells
(via sciencedaily.com) Original source A team of researchers has made a significant breakthrough in the field of organic photovoltaics.
Published Deer are expanding north, and that's not good for caribou
(via sciencedaily.com) Original source In the boreal forest of Western Canada, researchers have considered that both changing climate and increased habitat alteration have enabled deer to push farther north.
Published How do birds flock? Researchers do the math to reveal previously unknown aerodynamic phenomenon
(via sciencedaily.com) Original source How do birds fly in a coordinated and seemingly effortless fashion? Part of the answer lies in precise, and previously unknown, aerodynamic interactions, reports a team of mathematicians. Its breakthrough broadens our understanding of wildlife, including fish, who move in schools, and could have applications in transportation and energy.
Published Human activities have an intense impact on Earth's deep subsurface fluid flow
(via sciencedaily.com) Original source Hydrologists predict human-induced underground fluid fluxes to rise with climate change mitigation strategies like carbon sequestration.
