South Florida estuaries warming faster than Gulf of Mexico, global ocean, USF research shows      (via sciencedaily.com)     Original source 

Estuaries in South Florida have experienced rapid warming over the past two decades, including a record-breaking marine heat wave in 2023, research shows. The findings paint a troubling picture for the marine life that calls Florida home. Possible causes include evaporation, water capacity and residence time (the amount of time water spends in an estuary). No single factor has been identified as dominant.

New device for on-the-spot water testing      (via sciencedaily.com)     Original source 

Researchers at University of Galway have developed a new, portable technology for on-the-spot testing of water quality to detect one of the most dangerous types of bacteria. Ireland regularly reports the highest crude incidence rates of the pathogen Shiga toxigenic Escherichia coli -- STEC for short -- in Europe over the recent years.

Most existing heat wave indices fail to capture heat wave severity      (via sciencedaily.com)     Original source 

Even though climate change is bringing more frequent and severe heat waves, there is no standard, global way to measure heat-wave severity, and existing indices have different thresholds for defining dangerous heat-stress conditions. Researchers report that five out of six existing heat-wave indices were unable to capture the severity and spatial distribution of recent lethal heat waves in India, Spain, and the USA. The sixth index -- the lethal heat-stress index -- was better able to identify dangerous heat-stress conditions, particularly in low-humidity regions.

Scientists uncover hidden forces causing continents to rise      (via sciencedaily.com)     Original source 

Scientists have answered one of the most puzzling questions in plate tectonics: how and why 'stable' parts of continents gradually rise to form some of the planet's greatest topographic features.

New York City's fireworks display prompts temporary surge of air pollution      (via sciencedaily.com)     Original source 

In 2023, roughly 60,000 firework shells exploded above Manhattan's East River as part of Macy's Fourth of July show. The resulting air pollutant levels were many times higher in the hours after the display than those seen when smoke from a Canadian wildfire had blanketed the area a month before, according to the results of a new study.

Advanced chelators offer efficient and eco-friendly rare earth element recovery      (via sciencedaily.com)     Original source 

The world is going to need a lot of weird metals in the coming years, according to chemistry professor. But he isn't talking about lithium, cobalt or even beryllium. He's interested in dysprosium, which is so hidden in the periodic table that you'd be forgiven for thinking he made it up.

Stacking molecules like plates improves organic solar device performance      (via sciencedaily.com)     Original source 

Researchers found that how well light-converting molecules stack together in a solid is important for how well they convert light into electric current. A rigid molecule that stacked well showed excellent electricity generation in an organic solar cell and photocatalyst, easily outperforming a similar flexible molecule that did not stack well. This new way of improving the design of molecules could be used to pioneer the next generation of light-converting devices.

A new way of thinking about the economy could help protect the Amazon, and help its people thrive      (via sciencedaily.com)     Original source 

To protect the Amazon and support the wellbeing of its people, its economy needs to shift from environmentally harmful production to a model built around the diversity of indigenous and rural communities, and standing forests.

Groundwater reserves in southwestern Europe more stable overall than previously thought      (via sciencedaily.com)     Original source 

Groundwater is a vital resource, sustaining plants and ecosystems, ensuring agricultural production and serving as a core component of drinking water supplies. However, climate change and anthropogenic pressures can threaten groundwater availability, especially in southwestern Europe. This threat was evaluated by a research team using multidecadal data from more than 12,000 groundwater wells in Portugal, Spain, France, and Italy. The surprising finding: Groundwater levels are not declining everywhere as widely believed, but primarily in semi-arid regions with intensive agriculture and frequent droughts. Declines are also observed in temperate regions associated with large urban areas. The authors conclude that, with suitable management practices, groundwater can be utilized sustainably.

Ultrafine particles linked to over 1,000 deaths per year in Canada's two largest cities      (via sciencedaily.com)     Original source 

A new study conducted in Canada's two largest cities has linked about 1,100 premature deaths per year to an unregulated air pollutant. Ultrafine particles (UFPs) primarily come from vehicle emissions and industrial activities. Canada's federal and provincial governments have not set concentration limits for UFPs, as they have for larger fine particles known as PM2.5.

Link between global warming and rising sea levels      (via sciencedaily.com)     Original source 

A new study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the current trajectory, Antarctic ice loss could lead to more future sea level rise than previously thought.

New research sheds light on relationships between plants and insects in forest ecosystems      (via sciencedaily.com)     Original source 

Researchers have published new findings on how leaf-eating insects affect forest ecosystems worldwide. Researchers are aware of how large herbivores cycle nutrients in forests. They know much less, however, about how leaf-eating insects impact forest carbon and nutrient cycling.

Combined effects of plastic pollution and seawater flooding amplify threats to coastal plant species      (via sciencedaily.com)     Original source 

A new study highlights how a combination of environmental stressors -- namely plastic pollution and seawater flooding -- can increase the threats faced by plants in some of the planet's critical ecosystems. It showed that both stressors had some effects on the species tested, but being exposed to both microplastics and flooding together -- a threat likely to increase as a result of climate change and plastic use -- had a more pronounced impact on their resource allocation.

Genetic signatures of domestication identified in pigs, chickens      (via sciencedaily.com)     Original source 

Wild boars and red junglefowl gave rise to common pigs and chickens. These animals' genes evolved to express themselves differently, leading to signatures of domestication -- such as weaker bones and better viral resistance -- in pigs and chickens, according to a research team.
