Reducing aircraft soot emissions may not reduce contrail clouds, according to in-flight observations of emissions from a passenger jet with modern “lean-burn” engines, reported in Nature. Contrails from aircraft contribute to the climate-warming impacts of […]
A growing network of meltwater lakes at the edge of the Greenland ice sheet is accelerating the flow of major glaciers, potentially increasing the pace of global sea-level rise. Warmer air and sea temperatures have […]
In the search to replace antibiotic growth promoters with effective alternatives in modern swine production, plant-based essential oils are showing potential to provide lasting benefits. In a rare long-term public study that compared the effects […]
Rivers are rarely the calm, orderly streams we imagine on maps. Over time, their winding paths—called meanders—shift, bend, and occasionally snap off in sudden “cutoff” events that shorten loops and reshape the landscape. While scientists […]
While aquaculture has grown rapidly to meet global seafood demand, it is increasingly relying on species that are less beneficial for food security, climate mitigation, and biodiversity, said a new study from researchers at the […]
Emissions of two major pollutants have steadily decreased on Salt Lake City roads over the past two decades, while levels of carbon dioxide emissions, a related gas blamed for climate change, remained steady, according to […]
Researchers from the University of Maine, in partnership with the Maine Department of Marine Resources (DMR), are analyzing more than 20 years of fishery survey data from the Gulf of Maine to examine how environmental […]
Diverse soil microbial communities may help suppress pathogens naturally, acting as a biological barrier against their establishment and spread, according to a new study. Professor Brajesh Singh, from The University of Western Australia’s School of […]
Researchers have uncovered new evidence that short-lived spikes in ocean phosphorus may have played a major role in two of the most severe marine extinctions in Earth’s history. Dr. Matthew Dodd from The University of […]
The Syrian civil war, which began in 2011, caused widespread population displacement and infrastructure damage. However, it has also led to an unintended environmental effect with notable changes in the country’s landscape, according to a […]
