Published Hot traces in rock
(via sciencedaily.com) Original source Fluids circulating underground change rocks over the course of time. These processes must be taken into account if they are to be used as a climate archive. Researchers have used 380-million-year-old limestones from Hagen-Hohenlimburg to show in detail which climate information is still preserved in the rock.
Published A promising new method uses light to clean up forever chemicals
(via sciencedaily.com) Original source A room-temperature method to decompose perfluoroalkyl substances (PFASs) using visible LED light offers a promising solution for sustainable fluorine recycling and PFAS treatment.
Published Converting captured carbon to fuel: Study assesses what's practical and what's not
(via sciencedaily.com) Original source A new analysis sheds light on major shortfalls of a recently proposed approach to capture CO2 from air and directly convert it to fuel using electricity. The authors also provide a new, more sustainable, alternative.
Published Ecologists discover rare fiddler crab species on Hong Kong coast highlighting the impact of climate change and coastal development
(via sciencedaily.com) Original source Researchers have made an exciting discovery on the Hong Kong coast. They have identified two fiddler crab species: Tubuca dussumieri, previously recorded in old literature but never confirmed in recent times, and Tubuca. coarctata, which has never been seen in Hong Kong. These findings not only confirm the presence of these insular species in Hong Kong but also explore the potential impact of climate change on their distribution.
Published Maximizing hydrogen peroxide formation during water electrolysis
(via sciencedaily.com) Original source When water is split electrolytically, the result is typically hydrogen -- and 'useless' oxygen. Instead of oxygen, you can also produce hydrogen peroxide, which is required for many branches of industry. This, however, requires certain reaction conditions.
Published Deep-ocean floor produces its own oxygen
(via sciencedaily.com) Original source An international team of researchers has discovered that metallic minerals on the deep-ocean floor produce oxygen -- 13,000 feet below the surface. Discovery challenges long-held assumptions that only photosynthetic organisms generate Earth's oxygen. Minerals at the abyssal seafloor appear to act like geobatteries to produce oxygen in a process that does not require sunlight.
Published Fish adjust reproduction in response to predators
(via sciencedaily.com) Original source Some species of fish can evolve their egg-laying habits in response to predators in the area in order to survive, according to new research.
Published New humidity-driven membrane to remove carbon dioxide from the air
(via sciencedaily.com) Original source A new ambient-energy-driven membrane that pumps carbon dioxide out of the air has been developed by researchers.
Published How pollution may remain in water after oil spill cleanups
(via sciencedaily.com) Original source The way oil drops break up at the water's surface means some oil may not get cleaned up after a spill.
Published Solar farms with stormwater controls mitigate runoff, erosion, study finds
(via sciencedaily.com) Original source As the number of major utility-scale ground solar panel installations grows, concerns about their impacts on natural hydrologic processes also have grown. However, a new study by Penn State researchers suggests that excess runoff or increased erosion can be easily mitigated -- if these 'solar farms' are properly built.
Published Rural belts around cities can reduce urban summer temperatures by up to 0.5°C
(via sciencedaily.com) Original source The key to cooling 'urban heat islands' may lie in the countryside, according to a new study.
Published Microbes found to destroy certain 'forever chemicals'
(via sciencedaily.com) Original source An environmental engineering team has discovered that specific bacterial species can cleave the strong fluorine-to-carbon bond certain kinds of 'forever chemical' water pollutants, offering promise for low-cost treatments of contaminated drinking water.
Published Sea ice's cooling power is waning faster than its area of extent
(via sciencedaily.com) Original source As sea ice disappears and grows less reflective, the Arctic has lost around a quarter of its cooling power since 1980, and the world has lost up to 15%, according to new research.
Published Reef pest feasts on 'sea sawdust'
(via sciencedaily.com) Original source Researchers have uncovered an under the sea phenomenon where coral-destroying crown-of-thorns starfish larvae have been feasting on blue-green algae bacteria known as 'sea sawdust'.
Published Diatom surprise could rewrite the global carbon cycle
(via sciencedaily.com) Original source When it comes to diatoms that live in the ocean, new research suggests that photosynthesis is not the only strategy for accumulating carbon. Instead, these single-celled plankton are also building biomass by feeding directly on organic carbon in wide swaths of the ocean. These new findings could lead to reduced estimates regarding how much carbon dioxide diatoms pull out of the air via photosynthesis, which in turn, could alter our understanding of the global carbon cycle, which is especially relevant given the changing climate.
Published Aussie innovation spearheads cheaper seafloor test for offshore wind farms
(via sciencedaily.com) Original source Australian engineers have unveiled a clever new device -- based on a modified speargun -- as a cheap and efficient way to test seabed soil when designing offshore wind farms.
Published Smart soil can water and feed itself
(via sciencedaily.com) Original source A newly engineered type of soil can capture water out of thin air to keep plants hydrated and manage controlled release of fertilizer for a constant supply of nutrients.
Published Nature-based solutions to disaster risk from climate change are cost effective
(via sciencedaily.com) Original source A new global assessment of scientific literature finds that nature-based solutions (NbS) are an economically effective method to mitigate risks from a range of disasters -- from floods and hurricanes to heatwaves and landslides -- which are only expected to intensify as Earth continues to warm.
Published Scientists use machine learning to predict diversity of tree species in forests
(via sciencedaily.com) Original source Researchers used machine learning to generate highly detailed maps of over 100 million individual trees from 24 sites across the U.S. These maps provide information about individual tree species and conditions, which can greatly aid conservation efforts and other ecological projects.
Published Microplastic pollution increases sea foam height and stability
(via sciencedaily.com) Original source Researchers examine the specific impacts of microplastics on the geophysics of sea foam formation in the critical zone where water meets air in the top layer of the ocean. They devised two simulations for their work -- a column filled with sea water injected with air and a laboratory-scale breaking wave channel to test the impacts of wave height on sea foam in the surface microlayer -- and tested their effects on sea foam formation, stability, and duration.
