Published Ships now spew less sulfur, but warming has sped up (via sciencedaily.com) Original source
New findings document fewer ship tracks, reduced cloud cover, and boosted warming after ship emissions regulations took effect in 2020.
Published New study unveils 16,000 years of climate history in the tropical Andes (via sciencedaily.com) Original source
Researchers highlight the roles of carbon dioxide and ocean currents as key drivers of temperature fluctuations in the tropical Andes over a 16,000 year period.
Published Bacteria in lakes fight climate change (via sciencedaily.com) Original source
Methane-oxidizing bacteria could play a greater role than previously thought in preventing the release of climate-damaging methane from lakes, researchers from Bremen report. They also show who is behind the process and how it works.
Published Greenland mega-tsunami led to week-long oscillating fjord wave (via sciencedaily.com) Original source
In September 2023, a megatsunami in remote eastern Greenland sent seismic waves around the world, piquing the interest of the global research community. The event created a week-long oscillating wave in Dickson Fjord, according to a new report in The Seismic Record.
Published Finding pearls in the mud: Eco-friendly tungsten recovery from semiconductor waste (via sciencedaily.com) Original source
Semiconductor industry waste is typically seen as a costly disposal problem and an environmental hazard. But what if this waste could be transformed into a valuable resource? In an exciting development, researchers have unveiled an eco-friendly method to extract rare metals from semiconductor waste. This innovative approach not only recovers precious tungsten but also assesses its economic viability, offering a sustainable solution for waste management in the tech industry.
Published Effective new catalyst brings hope for cleaner energy, wastewater treatment, and green chemistry (via sciencedaily.com) Original source
A catalyst that significantly enhances ammonia conversion could improve wastewater treatment, green chemical and hydrogen production.
Published Unlocking the secrets of salt stress tolerance in wild tomatoes (via sciencedaily.com) Original source
As our climate changes and soil salinity increases in many agricultural areas, finding crops that can thrive in these challenging conditions is crucial. Cultivated tomatoes, while delicious, often struggle in salty soils. Their wild cousins, however, have evolved to survive in diverse and often harsh environments. A recent study delved into the genetic treasure trove of wild tomatoes to uncover secrets of salt tolerance that could be used to develop resilient crop varieties.
Published Alaskan land eroding faster due to climate change (via sciencedaily.com) Original source
A new study shows that frozen land in Alaska is eroding faster than it can be replaced due to climate change.
Published Forever chemical pollution can now be tracked (via sciencedaily.com) Original source
Researchers developed a way to fingerprint organofluorine compounds -- sometimes called 'forever chemicals' --which could help authorities trace them to their source when they end up in aquifers, waterways or soil.
Published Water delivered to the mantle by aluminum enriched hydrated slabs? (via sciencedaily.com) Original source
Researchers found a notable effect of aluminum on the sound velocities of superhydrous phase B, a dense hydrous magnesium silicate and potential host of water in the deep Earth. Their results suggest that aluminous phase B could explain seismic velocity anomalies in the Earth's mantle transition region and uppermost lower mantle.
Published 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.
Published 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.
Published 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.
Published 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.
Published Seismic detectors measure soil moisture using traffic noise (via sciencedaily.com) Original source
Using state of the art techniques, researchers use vibrations from traffic to measure underground soil moisture.
Published Research catalogs greenhouse gas emissions tied to energy use for interbasin water transfers (via sciencedaily.com) Original source
Much of the water in the West is transported across vast geographical areas by large infrastructure projects known as interbasin water transfers. Two of these projects in particular make up 85% of all energy-related greenhouse gas emissions associated with U.S. interbasin transfers -- one in Arizona and the other in California -- according to the new research.
Published Sustainable and reversible 3D printing method uses minimal ingredients and steps (via sciencedaily.com) Original source
A new 3D printing method developed by engineers is so simple that it uses a polymer ink and salt water solution to create solid structures. The work has the potential to make materials manufacturing more sustainable and environmentally friendly.
Published Multiple urinary metals play key role in cardiovascular disease and mortality, study finds (via sciencedaily.com) Original source
Higher levels of urinary metals such as cadmium, tungsten, uranium, cobalt, copper and zinc are linked to increased cardiovascular disease and mortality in a racially and ethnically diverse U.S. population, according to a new study.
Published Warming stops tiny organisms working together (via sciencedaily.com) Original source
