Published Mature forests vital in frontline fight against climate change
(via sciencedaily.com) Original source Mature forests have a key role to play in the fight against climate change -- extracting carbon dioxide (CO2) from the atmosphere and locking it into new wood.
Published Long-distance relationship revealed in the seemingly random behavior of bowhead whales
(via sciencedaily.com) Original source Applying chaos theory to the movement of iconic arctic whales uncovered a 24-hour diving cycle and a long-range (~100 km) synchronization.
Published Millions of years for plants to recover from global warming
(via sciencedaily.com) Original source Catastrophic volcanic eruptions that warmed the planet millions of years ago shed new light on how plants evolve and regulate climate. Researchers reveal the long-term effects of disturbed natural ecosystems on climate in geological history and its implications for today.
Published Researchers find unexpectedly large methane source in overlooked landscape
(via sciencedaily.com) Original source Researchers reported that upland landscapes were releasing some of the highest methane emissions yet documented among northern terrestrial ecosystems. The research was sparked when a potent greenhouse gas began ballooning under lawns in Fairbanks.
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 Mix of factors prompts owl monkeys to leave their parents
(via sciencedaily.com) Original source There comes a point in the lives of young owl monkeys when they leave their parents and strike out on their own to find a mate. In a new study of a wild population of Azara's owl monkeys in northern Argentina, researchers reveal that a combination of social and ecological factors influences when these tree-dwelling monkeys peel away from their parents and siblings. According to their findings -- which were based on 25 years of genetic and demographic data for several generations of owl monkeys, covering more than 330 individuals -- none of the individuals, regardless of their sex, reproduced in the same group where they were born. In all cases, the researchers found, the animals either departed from their natal group or died before reproducing.
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 Monitoring of nature reserves via social media and deep learning
(via sciencedaily.com) Original source Researchers have created a deep learning method to analyze social media images taken within protected green spaces to gain insights on human activity distribution as a way to monitor the ecological impacts of these activities.
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 report on Great Barrier Reef shows coral cover increases before onset of serious bleaching, cyclones
(via sciencedaily.com) Original source Coral cover has increased in all three regions on the Great Barrier Reef and is at regional highs in two of the three regions, according to a new report. But the results come with a note of caution.
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 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.
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 Antarctic-wide survey of plant life to aid conservation efforts
(via sciencedaily.com) Original source The first continent-wide mapping study of plant life across Antarctica reveals growth in previously uncharted areas and is set to inform conservation measures across the region. The satellite survey of mosses, lichens and algae across the continent will form a baseline for monitoring how Antarctica's vegetation responds to climate change.
