Published Coal-based product could replace sand in concrete
(via sciencedaily.com) Original source A new study found that graphene derived from metallurgical coke, a coal-based product, through flash Joule heating could serve not only as a reinforcing additive in cement but also as a replacement for sand in concrete.
Published Permeable pavements could reduce coho-killing tire pollutants
(via sciencedaily.com) Original source The pore-like structure of permeable pavements may help protect coho salmon by preventing tire wear particles and related contaminants from entering stormwater runoff, according to a recent study. Researchers demonstrated that four types of permeable pavements can act as giant filters, retaining more than 96% of applied tire particle mass. They also captured several tire-associated chemicals, resulting in a 68% average reduction of 6PPD-quinone, a contaminant shown to kill coho salmon in urban streams.
Published Women exposed to toxic metals may experience earlier aging of their ovaries
(via sciencedaily.com) Original source Middle-aged women who are exposed to toxic metals may have fewer eggs in their ovaries as they approach menopause, according to new research.
Published 2020 US rule dramatically deregulated wetlands, streams and drinking water
(via sciencedaily.com) Original source New research used machine learning to more accurately predict which waterways are protected by the Clean Water Act. The analysis found that a 2020 Trump administration rule removed Clean Water Act protection for one-fourth of US wetlands and one-fifth of US streams, and also deregulated 30% of watersheds that supply drinking water to household taps.
Published Tiny ant species disrupts lion's hunting behavior
(via sciencedaily.com) Original source Data gathered through years of observation reveal an innocuous-seeming ant is disrupting an ecosystem in East Africa, illustrating the complex web of interactions among ants, trees, lions, zebras and buffaloes.
Published The underground network: Decoding the dynamics of plant-fungal symbiosis
(via sciencedaily.com) Original source The intricate dance of nature often unfolds in mysterious ways, hidden from the naked eye. At the heart of this enigmatic tango lies a vital partnership: the symbiosis between plants and a type of fungi known as arbuscular mycorrhizal (AM) fungi. New groundbreaking research delves into this partnership, revealing key insights that deepen our understanding of plant-AM fungi interactions and could lead to advances in sustainable agriculture.
Published Diverse forests are best at standing up to storms
(via sciencedaily.com) Original source European forests with a greater diversity of tree species are more resilient to storms, according to new research.
Published Sparrows uniquely adapted to Bay Area marshes are losing their uniqueness
(via sciencedaily.com) Original source How does loss of habitat affect the animals still living there? A genetic study of saltwater-adapted Savannah sparrows around the San Francisco Bay Area shows that the 90% loss of tidal marsh habitat has led to more interbreeding with freshwater-adapted Savannah sparrows, diminishing their genetic adaptation to saltwater, such as enlarged kidneys and larger beak. This could lessen their ability to live in a saltwater habitat.
Published Researchers advocate for sustainable logging to safeguard against global flood risks
(via sciencedaily.com) Original source It's time to recognize the power of healthy forests in managing global growing flood risk, and to shift towards more sustainable forestry practices and policy.
Published A new design improves water decontamination via plasma jet
(via sciencedaily.com) Original source Two research groups design a plasma (an ionized gas) reactor maintained by microwaves that makes it possible to decontaminate waters with high concentrations of dye.
Published The complexity of forests cannot be explained by simple mathematical rules, study finds
(via sciencedaily.com) Original source The way trees grow together do not resemble how branches grow on a single tree, scientists have discovered.
Published Paper provides a clearer picture of severe hydro hazards
(via sciencedaily.com) Original source A new study now provides a global examination of drought-pluvial volatility -- or the tendency to shift from one weather extreme to another.
Published 'Talking' tomatoes: How their communication is influenced by enemies and friends
(via sciencedaily.com) Original source Plants produce a range of chemicals known as volatile organic compounds that influence their interactions with the world around them. In a new study, researchers investigated how the type and amount of these VOCs change based on different features of tomato plants.
Published Global groundwater depletion is accelerating, but is not inevitable
(via sciencedaily.com) Original source Groundwater is rapidly declining across the globe, often at accelerating rates. Researchers now present the largest assessment of groundwater levels around the world, spanning nearly 1,700 aquifers. In addition to raising the alarm over declining water resources, the work offers instructive examples of where things are going well, and how groundwater depletion can be solved. The study is a boon for scientists, policy makers and resource managers working to understand global groundwater dynamics.
Published World's largest database of weeds lets scientists peer into the past, and future, of global agriculture
(via sciencedaily.com) Original source A new database of weeds that can help scientists understand how traditional agricultural systems were managed throughout history, could also provide insights into how global trends like the climate crisis could affect the resilience of our modern day food systems.
Published Injectable water filtration system could improve access to clean drinking water around the world
(via sciencedaily.com) Original source A new portable filtration system collects dirty water with a syringe and injects it into a hydrogel filter that weeds out nearly all tiny particles.
Published Study offers rare long-term analysis of techniques for creating standing dead trees for wildlife habitat
(via sciencedaily.com) Original source Ecologists have long known that standing dead trees, commonly referred to as snags, are an important habitat element for forest dwellers and act as a driver of biodiversity. They're so important that in some managed forests, snag creation is part of the conservation tool kit -- i.e., crews sometimes convert a percentage of live trees into dead ones through techniques ranging from sawing off their tops to wounding their trunks to injecting them with disease-causing fungi.
Published Water, water everywhere and now we may have drops to drink
(via sciencedaily.com) Original source Researchers have achieved a major breakthrough in Redox Flow Desalination (RFD), an emerging electrochemical technique that can turn seawater into potable drinking water and also store affordable renewable energy.
Published Discovering the physics behind 300-year-old firefighting methods
(via sciencedaily.com) Original source Inspired by a 1725 fire engine that pumped water at larger distances and higher speeds than previously possible, authors analyzed the pressure chamber's Windkessel effect to capture the physics behind this widely used, enduring technology. They compared the initial state of the chamber, the rate at which bucket brigades could pour water in (volumetric inflow), the length of time pressure builds, and the effects on output flow rate. Next, the authors plan to examine the physiological Windkessel involved in the heart-aorta system.
Published Innovative tech shows promise to boost rubber production in US
(via sciencedaily.com) Original source With disease and high demand posing threats to the world's primary natural rubber supply in Southeast Asia, scientists are working to ramp up the U.S. rubber market by advancing methods to extract latex from two sustainable North American plant sources: a dandelion species and a desert shrub.
