Advancing towards sustainability: Turning carbon dioxide and water into acetylene
Reaching sustainability is one of humanity's most pressing challenges today—and also one of the hardest. To minimize our impact on the environment and start reverting the damage humanity has already caused, striving to achieve carbon neutrality in.....»»
New process quickly transforms livestock manure into biochar
A technology has been developed to quickly convert livestock manure, a significant issue in animal farming, into valuable "black gold" rich in carbon within a day......»»
Philippine settlement submerged by dam reappears due to drought
A centuries-old settlement submerged by the construction of a dam in the northern Philippines in the 1970s has reappeared as water levels drop due to a drought affecting swathes of the country......»»
Drinking water in low-income communities is more likely to be contaminated by "forever chemicals," research finds
PFAS, or forever chemicals, are widespread and more likely to be found in public water systems serving low-income communities and communities of color in New Jersey, according to new research from Northeastern University......»»
Managing meandering waterways in a changing world
Just as water moves through a river, rivers themselves move across the landscape. They carve valleys and canyons, create floodplains and deltas, and transport sediment from the uplands to the ocean......»»
Scientists combine a spatially distributed sediment delivery model and biogeochemical model to estimate fluxes by water
Water erosion is the most active process controlling soil formation and evolution, which can affect the redistribution of carbon between terrestrial, aquatic, and atmospheric ecosystems. Erosion-induced organic carbon dynamic process should not be mi.....»»
Tesla"s freshened Model 3 Performance is a crazy fast, 510-hp bargain
Tesla adds adaptive suspension, improved sport seats and carbon-fiber interior accents. The performance trim is also the only Model 3 eligible for the $7,500 EV credit, making it a bargain......»»
EPA issues four rules limiting pollution from fossil fuel power plants
Coal to be hit hard, natural gas plants will have to capture carbon emissions. Enlarge (credit: Jose A. Bernat Bacete) Today, the US Environmental Protection Agency announced a suite of rules that target pollution from f.....»»
Synthesis of two new carbides provides perspective on how complex carbon structures could exist on other planets
Researchers at the University of Bayreuth have gained new insights in the field of high-pressure carbon chemistry: They synthesized two new carbides—compounds of carbon and another chemical element—with unique structures. The results may provide.....»»
Cocaine is an emerging contaminant of concern in the Bay of Santos (Brazil), says researcher
In addition to already known pollutants, the Bay of Santos—a city in the state of São Paulo (Brazil) that is home to the largest seaport in Latin America—has been affected by an emerging contaminant that is now present not only in the water but.....»»
A better way to predict Arctic riverbank erosion
Arctic riverbanks are typically resilient, thanks to the power of permafrost. This permanently frozen soil locks in sediment, leading to low erosion rates. But as Arctic river water warms due to climate change, some researchers worry that riverbanks.....»»
US announces sweeping cuts to power sector carbon emissions
President Joe Biden's government on Thursday finalized sweeping plans to curb planet-warming emissions from the nation's fossil fuel plants as part of the United States' efforts to confront the climate crisis......»»
The guardian angels of the source of the Seine
The river Seine, the centerpiece of the Paris Olympics opening ceremony in July, starts with a few drops of water in a mossy grotto deep in the woods of central France......»»
Shoreline model predicts long-term future of storm protection and sea-level rise
Researchers in North Carolina have created a simulation model to analyze how coastal management activities meant to protect barrier islands from sea-level rise can disrupt the natural processes that are keeping barrier islands above water......»»
Artificial intelligence helps scientists engineer plants to fight climate change
The Intergovernmental Panel on Climate Change (IPCC) has declared that removing carbon from the atmosphere is now essential to fighting climate change and limiting global temperature rise. To support these efforts, Salk Institute scientists are harne.....»»
Africa"s megacities threatened by heat, floods, disease—action needed to start greening, adapt to climate change
Cities cover just 3% of the planet. But they emit 78% of all global greenhouse gas emissions, absorb 80% of final global energy (what consumers use) and consume 60% of clean drinking water......»»
A chemical mystery solved—the reaction that explains large carbon sinks
A mystery that has puzzled the scientific community for more than 50 years has finally been solved. A team from Linköping University, Sweden, and Helmholtz Munich have discovered that a certain type of chemical reaction can explain why organic matte.....»»
Nanofibers rid water of hazardous dyes: Researchers develop efficient filters based on cellulose waste
Using waste to purify water may sound counterintuitive. But at TU Wien, this is exactly what has now been achieved. Researchers have developed a special nanostructure to filter a widespread class of harmful dyes from water......»»
Future hurricanes could compromise New England forests" ability to store and sequester carbon
Nature-based climate solutions can help mitigate climate change, especially in forested regions capable of storing and sequestering vast amounts of carbon. New research published in Global Change Biology indicates that a single hurricane in New Engla.....»»
Why canned wine can smell like rotten eggs while beer and Coke are fine
Sulfur dioxide in the wine reacts with the aluminum to make hydrogen sulfide. Enlarge (credit: BackyardProduction/Getty Images) True wine aficionados might turn up their noses, but canned wines are growing in popularity.....»»
Study finds climate change is helping tropical fish invade Australian ocean water
A University of Adelaide study of shallow-water fish communities on rocky reefs in south-eastern Australia has found climate change is helping tropical fish species invade temperate Australian waters. The work is published in the Journal of Animal Ec.....»»
